Description
Technical Field
The invention relates to the technical field of vehicle body parts, in particular to a hydraulic assembly supported on a hydraulic shock absorber, the upper support of the shock absorber and an installation structure of the upper support.
Background
At present, the structure supported on the shock absorber comprises an inner framework, a rubber main spring wrapped on the edge of the inner framework and an outer framework fixed on the outer surface of the rubber main spring, wherein the inner framework, the rubber main spring and the outer framework are integrally vulcanized. The conventional upper support of the damper is simple in structure and low in cost, and can provide certain rigidity strength and damping requirements required by the damper.
However, existing upper supports for shock absorbers suffer from the following disadvantages:
1. The damping performance is limited, namely the damping coefficient of the rubber main spring is lower, and is usually only 0.1-0.2, and the damping effect provided by the rubber main spring is very limited. This means that in the vibration damping process, the damping capacity for vibration is relatively weak, and vibration energy cannot be quickly and effectively eliminated, which may cause the vehicle to feel more residual vibration and jolt in the driving process, and influence the driving comfort and stability.
2. The rubber material is easy to age due to the influence of environmental factors, such as oxygen and ozone erosion caused by long-term exposure to air, accelerated aging process under high-temperature environment and embrittlement under cold climate condition. In addition, heat generated in the running process of the vehicle, salt on the road, chemical substances and the like can damage the rubber main spring, so that the performance of the rubber main spring is gradually reduced, and the service life of the rubber main spring is shortened.
3. The strength and the wear resistance are insufficient, namely the strength of the rubber main spring is relatively low, and the rubber main spring is easy to wear, deform and even break when bearing larger pressure and friction force for a long time. Particularly, under severe road conditions, such as roads with more pits or frequent driving behaviors such as rapid acceleration and rapid braking, the rubber main spring can be subjected to larger pressure, so that the abrasion speed of the rubber main spring is increased, and the normal work of the support on the shock absorber is influenced.
4. Is sensitive to temperature, and the performance of the rubber main spring can be greatly changed along with the change of temperature. In a low-temperature environment, the rubber main spring can be hardened and has poor elasticity, so that the cushioning effect of the support on the shock absorber is weakened, and the vibration and impact feeling during running of the vehicle can be enhanced.
5. The control performance is affected by the fact that the elasticity of the rubber main spring is large, and the response speed of a suspension system is possibly reduced in the running process of a vehicle, so that the control performance of the vehicle is affected. For example, at high speeds, the steering and braking response of the vehicle may be less sensitive, reducing the safety of driving and the accuracy of steering.
Disclosure of Invention
The invention aims to solve the defects of the background technology and provide the hydraulic assembly of the upper support of the hydraulic shock absorber, the upper support of the shock absorber and the mounting structure thereof, wherein the hydraulic assembly has good damping performance, difficult ageing, good strength and wear resistance, insensitivity to temperature, excellent control performance and capability of effectively damping the vibration transmitted to a vehicle body by a tire and improving the riding comfort.
The hydraulic assembly comprises an inner framework, an upper liquid chamber and a lower liquid chamber which are coaxially arranged on the upper side and the lower side of the middle of the inner framework, wherein a liquid inlet channel which is communicated with the upper liquid chamber and is blocked by a liquid inlet and a connecting channel which is communicated with the upper liquid chamber and the lower liquid chamber are arranged in the inner framework, and the liquid inlet channel, the upper liquid chamber, the connecting channel and the lower liquid chamber form a closed space which can be elastically deformed, and damping liquid is filled in the closed space.
In the structure of the hydraulic assembly, the inner framework serves as a core supporting structure of the whole hydraulic assembly, and provides a mounting and fixing basis for other components. It is generally made of a high strength metallic material, having sufficient strength and rigidity to withstand various stresses generated during running of the vehicle. The design of the inner frame needs to consider the precision of matching with other parts and the convenience of installation, and ensures the stability and reliability of the whole hydraulic assembly. The upper liquid chamber and the lower liquid chamber are respectively positioned at the upper side and the lower side of the middle part of the inner framework and are coaxially arranged. They are the main space for storing damping fluid in the hydraulic assembly and are communicated with each other through the connecting flow channels. The shape and size of the liquid chamber can affect the flow characteristics and damping effect of the damping liquid. In general, a larger fluid chamber may store more damping fluid, providing greater damping capacity, but also increasing the volume and weight of the overall hydraulic assembly. The walls of the liquid chamber are typically made of a corrosion resistant, high strength material to ensure that the damping liquid does not leak or become contaminated during long term use. The liquid inlet channel is arranged in the inner framework and is communicated with the liquid feeding chamber, and the liquid inlet is blocked. The function of the liquid inlet flow channel is to inject damping liquid into the liquid feeding chamber in the assembly process of the hydraulic assembly. Once the injection is completed, the inlet is blocked to prevent leakage of the damping fluid. The connecting runner is also arranged in the inner framework and communicates the upper liquid chamber with the lower liquid chamber, so that damping liquid can flow between the two liquid chambers. The design of the connecting flow channel needs to consider the flow and pressure requirements of the damping fluid so as to ensure that the hydraulic assembly can work normally. The size, shape and layout of the inlet and connecting channels can affect the flow rate and resistance of the damping fluid, and thus the performance of the support on the shock absorber. The liquid inlet flow passage, the liquid feeding chamber, the connecting flow passage and the liquid discharging chamber form a closed space capable of generating elastic deformation. The tightness of this closed space is critical, and it ensures that the damping fluid does not leak during operation, thus ensuring the stability and reliability of the support on the shock absorber. The elastic deformation characteristic of the closed space is determined by the material characteristics of the inner framework, the liquid chamber wall surface and the connecting flow channel. When the upper support of the shock absorber receives vibration and impact from a road surface in the running process of the vehicle, the closed space can be correspondingly deformed, so that damping liquid flows between the liquid chambers to generate damping force, and the shock absorber has a shock absorbing effect. Damping fluid is the core working medium of the hydraulic assembly, which fills the enclosed space, consuming vibration and impact energy through flow and deformation. The properties of the damping fluid directly influence the damping effect and the performance stability of the support on the damper. Damping fluids generally have a relatively high viscosity and good flowability, and are capable of rapid flow between the fluid chambers, resulting in a sufficient damping force. Meanwhile, the damping fluid also needs to have good chemical stability and high-temperature and low-temperature resistance so as to ensure normal operation in various severe working environments. Different types of damping fluid have different performance characteristics and can be selected according to specific requirements and use environments of the vehicle. For example, some high performance damping fluids may provide greater damping capacity and better handling characteristics, but are also relatively expensive.
Further, the inner framework comprises an inner framework main shaft and an inner framework circular ring coaxially and fixedly connected to the circumferential surface of the middle part of the inner framework main shaft, the inner framework main shaft coaxially penetrates through the upper liquid chamber and the lower liquid chamber, the upper liquid chamber is located above the inner framework circular ring, and the lower liquid chamber is located below the inner framework circular ring.
The main shaft of the inner skeleton is the core part of the whole inner skeleton, and plays a main role in supporting and connecting. Are typically made of high strength metallic materials with sufficient strength and rigidity to withstand the various forces and stresses from the vehicle during travel. The shape of the main axis of the inner frame is generally cylindrical, and the diameter and length of the main axis are determined according to the specific design requirements of the support on the shock absorber. Its surface is usually precision machined to ensure mating accuracy and mounting stability with other components. The main shaft of the inner skeleton coaxially penetrates through the upper liquid chamber and the lower liquid chamber, and a foundation is provided for positioning and fixing the liquid chambers. Meanwhile, a space is provided for the arrangement of the connecting flow channels, so that damping liquid can smoothly flow between the liquid chambers. The inner skeleton ring is coaxially and fixedly connected to the middle circumferential surface of the inner skeleton main shaft, and forms a main body structure of the inner skeleton together with the inner skeleton main shaft. The inner skeleton ring has the functions of separating the upper liquid chamber from the lower liquid chamber and providing support for the sealing and fixing of the liquid chamber. The diameter of the inner skeleton ring is generally matched with the diameter of the main shaft of the inner skeleton, so that firm and reliable connection between the inner skeleton ring and the main shaft is ensured. The thickness and width of the hydraulic assembly are determined according to the design requirement of the liquid chamber, so that not only are enough strength and rigidity ensured, but also the volume and weight of the whole hydraulic assembly are reduced as much as possible. The inner skeleton ring is made of high-strength metal material and is generally the same as the main shaft of the inner skeleton. During the manufacturing process, the inner skeleton ring is usually fixed with the inner skeleton main shaft by welding, threaded connection or other reliable connection methods, so as to ensure that the inner skeleton ring cannot loosen or fall off during the running process of the vehicle. The upper liquid chamber is positioned above the inner framework circular ring and is an important part for storing damping liquid in the hydraulic assembly.
Further, the peripheral edge of the inner skeleton ring is wrapped and connected in the main spring which can be elastically deformed, an upper leather bag and a lower leather bag which can be elastically deformed are respectively fixed on the upper side and the lower side of the main spring, the upper leather bag, the upper surface of the main spring and the upper surface of the middle part of the inner skeleton enclose the upper liquid chamber, and the lower leather bag, the lower surface of the main spring and the lower surface of the middle part of the inner skeleton enclose the lower liquid chamber.
The circumferential edge of the inner framework ring is wrapped and connected in the main spring which can be elastically deformed, and the main spring can be tightly attached to the inner framework ring in a connecting mode, so that relative displacement between the main spring and the inner framework ring in the working process is avoided. The wrapping connection may be achieved in a number of ways, for example by vulcanization, adhesive or mechanical fastening. These connection means are required to ensure sufficient connection strength and sealing between the main spring and the inner frame ring to prevent leakage of the damping fluid. The main spring is generally made of a material having good elasticity and wear resistance, such as rubber, polyurethane, etc. The elastic deformation characteristic of the shock absorber can play a role in buffering and absorbing energy when the shock absorber supports and receives vibration and impact. The upper leather bag and the lower leather bag can elastically deform and are respectively positioned at the upper side and the lower side of the main spring. In the working process, the leather bag can correspondingly deform along with the deformation of the main spring, so that the tightness of the upper liquid chamber and the lower liquid chamber is kept. The material of the bellows is generally chosen from rubber or other synthetic materials having good elasticity, corrosion resistance and wear resistance. The materials can maintain stable performance in the long-term use process, and ensure the reliability of the hydraulic assembly. The upper surface of the upper leather bag and the main spring and the upper surface of the middle part of the inner framework enclose an upper liquid chamber, and the lower surface of the lower leather bag and the main spring and the lower surface of the middle part of the inner framework enclose a lower liquid chamber. The structural design ensures that the liquid chamber has good sealing performance and can effectively store damping liquid. The connection between the bellows and the main spring and inner frame needs to ensure a tight fit to prevent leakage of the damping fluid. Meanwhile, the elastic deformation characteristic of the leather bag plays roles of buffering and adjusting pressure when the internal pressure of the liquid chamber changes. When the upper support of the shock absorber is subjected to vibration and impact, the main spring, the upper leather bag and the lower leather bag are elastically deformed, so that the volume and the internal pressure of the liquid chamber are changed. The elastic deformation adjustment can enable damping liquid to flow between liquid chambers, and generate proper damping force so as to adapt to different vibration and impact conditions. The elastic deformation adjustment characteristics of the fluid chamber need to be matched to the overall performance requirements of the support on the shock absorber to ensure good shock absorption under various operating conditions.
Furthermore, the liquid inlet flow channel is arranged in the main shaft of the inner framework, and the connecting flow channel is arranged in the circular ring of the inner framework.
The liquid inlet channel is arranged in the inner skeleton main shaft, and the design fully utilizes the inner space of the inner skeleton main shaft, so that the structure of the whole hydraulic assembly is more compact. The choice of the position of the inlet flow channel needs to take into account the convenience of connection with the upper liquid chamber and the feasibility of operation during assembly. In general, the liquid inlet channel is communicated with the liquid feeding chamber in a manner as direct as possible, so as to ensure that the damping liquid can be smoothly injected. The size and shape of the liquid inlet flow channel need to be reasonably designed according to the flow rate and injection speed of the damping liquid. Generally, a larger inlet flow passage may increase the injection rate, but may also increase the volume and weight of the hydraulic assembly. The connecting runner is arranged in the inner framework ring, and the connecting runner can be tightly connected with the upper liquid chamber and the lower liquid chamber through the design, so that the smooth flow of damping liquid between the two liquid chambers is realized. The inner skeleton ring is used as a structure for separating the upper liquid chamber from the lower liquid chamber, and the connecting flow passage is arranged in the inner skeleton ring, so that the length and the resistance of the flow passage can be effectively reduced, and the flow efficiency of damping liquid is improved. The connecting flow channel is used for communicating the upper liquid chamber with the lower liquid chamber, so that damping liquid can flow between the two liquid chambers to generate damping force, and the damping force is exerted to play a role in vibration reduction. The size, shape and layout of the connecting channels can affect the flow and pressure distribution of the damping fluid and thus the performance of the support on the shock absorber. The reasonable design of the connecting flow channel can ensure that the damping liquid flows stably and uniformly between the liquid chambers, and the vibration reduction effect is improved.
Further, the connecting flow passage comprises an arc-shaped flow passage which is concentrically arranged with the inner framework ring.
The connecting flow passage and the inner framework ring are concentrically arranged, and the design has various advantages. Firstly, the concentric arrangement makes the runner more regular in space, is favorable to improving the compact structure and the stability of hydraulic assembly. Secondly, the concentric arrangement can ensure that the connection between the flow channel and the upper liquid chamber and the lower liquid chamber is more uniform, so that the flow of damping liquid between the liquid chambers is more stable. The concentric arrangement also facilitates machining and assembly during manufacturing, reducing manufacturing difficulties and costs. Meanwhile, the layout is also beneficial to improving the sealing performance of the hydraulic assembly and reducing the risk of leakage of damping fluid. By adopting the circular arc-shaped flow channel design, the length of the flow channel can be increased on one hand, so that the flow resistance of damping liquid in the flow channel is increased to a certain extent, and the vibration reduction effect is improved. On the other hand, the circular arc-shaped flow channel can enable the flow of the damping fluid to be smoother, and pressure loss and energy loss in the flow channel are reduced. The radius of curvature of the circular arc runner needs to be reasonably selected according to specific design requirements. A larger radius of curvature may reduce local resistance in the flow passage, but may increase the volume and weight of the hydraulic assembly, and a smaller radius of curvature may increase the compactness of the flow passage, but may result in poor flow of the damping fluid and increased pressure loss. The circular arc-shaped flow channels and the concentric arrangement can make the flow of damping liquid between the liquid chambers more complex, and increase the generation mechanism of damping force. This complex flow can better dissipate vibration and impact energy and improve the damping performance of the support on the shock absorber. Meanwhile, the size and the shape of the connecting flow channel are adjusted, so that the damping force and the characteristics can be adjusted, and the requirements of different vehicles and running conditions can be met. The response speed of the hydraulic assembly can be improved through the reasonably designed connecting flow passage. The circular arc-shaped flow channel can enable damping liquid to flow in the flow channel more quickly, so that the upper support of the damper can react to vibration and impact more quickly. The concentric arrangement ensures that the connection between the flow channel and the liquid chamber is tighter, and reduces the delay of damping liquid in the flowing process. The faster response speed can improve the running stability and the comfort of the vehicle, and particularly can better protect the vehicle and passengers under high-speed running and complex road conditions. The concentric arrangement and the circular arc-shaped runner can enable the stress of the runner to be more uniform, and the risk of fatigue damage and cracking of the runner in the long-term use process is reduced. In addition, the reasonable flow passage design can also reduce pressure peak value and local stress concentration in the flow passage, and improve the overall reliability and durability of the hydraulic assembly.
Further, the upper leather bag and the lower leather bag comprise through holes, annular leather bag outer skins and leather bag inner liners, wherein the through holes and the annular leather bag outer skins correspond to the inner skeleton main shafts, the leather bag inner liners are arranged inside the leather bag outer skins along the circumferential direction of the leather bag outer skins, the circumferential edges of the leather bag outer skins are clamped and arranged in the main springs, and the middle parts of the leather bag outer skins are fixed on the inner skeleton main shafts.
The upper leather bag and the lower leather bag are respectively provided with an annular leather bag outer skin, and the middle of the annular leather bag outer skin is provided with a through hole corresponding to the main shaft of the inner framework. The function of this via is to allow the endoskeleton spindle to pass through the bellows, ensuring that the bellows is properly installed in the hydraulic assembly. The skin of the bellows is usually made of a material having good elasticity and wear resistance, such as rubber or the like. The ring shape of the device can be matched with the main spring and the inner framework to form a sealed liquid chamber space. The thickness and material of the bladder skin need to be selected according to specific usage requirements to ensure that it can withstand the pressure within the fluid chamber and external forces, while having sufficient elasticity to accommodate the operational deformation of the hydraulic assembly. The leather bag lining is arranged inside the leather bag sheath along the circumferential direction of the leather bag sheath, so that the strength and stability of the leather bag are enhanced. The bladder lining may take different materials and structural forms, such as fiber reinforced materials, metal mesh, and the like. The function of the leather bag lining is to prevent the leather bag skin from excessively deforming or cracking in the working process of the leather bag, and the service life and the reliability of the leather bag are improved. Meanwhile, the shape of the leather bag can be maintained, and the sealing performance of the liquid chamber is ensured. The peripheral edge joint of the leather bag outer skin is arranged in the main spring. The clamping connection mode can ensure firm and reliable connection between the leather bag and the main spring, and prevent separation or leakage in the working process. The snap-fit connection often requires the design of suitable snap-fit structures, such as grooves, flanges, etc., to ensure that the bellows can be tightly snapped into the main spring. The middle part of the leather bag outer skin is fixed on the main shaft of the inner framework. The fixed connection mode can ensure that the leather bag cannot displace relative to the main shaft of the inner framework in the working process, and ensures the tightness and stability of the liquid chamber. The fixed connection may be by various means such as bolting, welding, bonding, etc. The specific connection mode needs to be selected according to the materials and structural characteristics of the leather bag and the inner skeleton main shaft so as to ensure the strength and the reliability of connection.
Further, the circumferential edge of the main spring is fixedly connected with an annular outer framework, and the outer framework can enable the main spring to be clamped and fixed with the upper leather bag and the lower leather bag in a radial clamping mode.
The outer framework is of an annular structure and is matched with the shape of the main spring. Are typically made of high strength metallic materials with sufficient rigidity and strength to withstand clamping forces from the outside and compressive forces from the inside. The size and shape of the main spring are designed according to the specifications of the main spring, the upper leather bag and the lower leather bag, so that the peripheral edge of the main spring can be tightly wrapped and well matched with the main spring. The outer skeleton makes the main spring and the upper leather bag and the lower leather bag clamped and fixed in a radial clamping mode. The fixing mode can ensure that the main spring cannot displace or loosen in the working process, and the structural stability of the hydraulic assembly is maintained. The existence of the outer skeleton enhances the structural strength of the whole upper support of the shock absorber and improves the shock resistance and deformation resistance of the shock absorber. The radial clamping mode is relatively simple and easy to operate. In the installation process, the main spring and the leather bag can be clamped and fixed by applying radial pressure to the external framework through a specific clamping tool or device. The installation mode does not need complex mechanical connection or welding process, and saves installation time and cost. The radial clamping force can be adjusted according to actual needs. The clamping force can be controlled by adjusting the pressure of the clamping tool or using clamping devices with different specifications, so that the main spring and the leather bag with different size and performance requirements are adapted. The adjustability enables the design of the support on the shock absorber to be more flexible and can meet the requirements of different vehicles and driving conditions. The radial clamping mode can provide even clamping force, so that the clamping between the main spring and the leather bag is firmer and more reliable. In the working process, the clamping mode can effectively prevent the loosening or separation of the main spring and the leather bag, and ensures the tightness and stability of the hydraulic assembly. Meanwhile, the vibration absorber can bear certain vibration and impact, and the reliability and durability of the upper support of the vibration absorber are improved. The main spring is fixedly clamped with the upper leather bag and the lower leather bag, so that the tightness of the liquid chamber is ensured, damping liquid can normally flow in the liquid chamber, and an effective damping force is generated. The radial clamping mode of the outer framework is beneficial to maintaining the sealing performance, so that the vibration reduction effect of the vibration absorber is improved, and vibration and jolt in the running process of the vehicle are reduced. The stable hydraulic assembly structure contributes to improvement of the steering stability of the vehicle. The outer framework can reduce the deformation and displacement of the main spring and the leather bag, and ensure that the shock absorber can provide consistent performance under different running conditions. This is important for improving steering accuracy, braking performance, and running stability of the vehicle. The reliable clamping and fixing mode and the firm outer skeleton structure can prolong the service life of the upper support of the shock absorber. They can withstand long-term operating pressures and external environmental effects, reduce the frequency of maintenance and replacement due to loosening or damage of components, and reduce the cost of use.
Further, a plurality of bosses with different heights are arranged on the surfaces of the upper side and the lower side of the main spring at intervals along the circumferential direction of the main spring.
The upper and lower both sides surface of above-mentioned main spring all is provided with the boss, and along its circumference direction interval distribution. This arrangement enables the boss to provide support and cushioning at different locations on the main spring. The arrangement of the bosses at intervals can be reasonably designed according to the size and the working requirement of the main spring so as to ensure that the bosses can effectively play roles in different positions. The difference in height of the bosses is an important feature. The design can enable the bosses with different heights to bear load in sequence when the main spring is stressed, so that progressive deformation and buffering are realized. The bosses with different heights can be accurately adjusted according to the working pressure and deformation requirements of the main spring so as to provide more optimized vibration reduction performance. The boss can increase the local rigidity and strength of the main spring, and improve the supporting capacity of the main spring to external loads. When the shock absorber is supported to work, the boss can bear the pressure from the upper leather bag, the lower leather bag and other parts, so that the main spring is prevented from being excessively deformed. The bosses with different heights can be reasonably distributed according to the stress condition of the main spring, so that the main spring can provide enough supporting force at different positions, and the stability of the whole hydraulic assembly is improved. The existence of the boss can change the elastic characteristic of the main spring, so that the main spring can absorb and disperse energy more effectively when being subjected to vibration and impact. The bosses with different heights can provide different degrees of elastic deformation, so that finer vibration reduction adjustment is realized. The design of the boss can enable the main spring to have different rigidity and damping characteristics in different working stages, adapt to different running conditions and road conditions, and improve the vibration reduction effect and riding comfort of the vehicle. The boss on the main spring interacts with the upper and lower bellows to influence the pressure distribution of the fluid chamber. When the main spring is deformed, the boss can change the volume and shape of the liquid chamber, thereby adjusting the damping hydraulic pressure in the liquid chamber. Through the height and the distribution of the reasonable design boss, the accurate control of the hydraulic chamber pressure can be realized, and the vibration damping performance and the response speed of the hydraulic assembly are improved. The reinforcing supporting force effect of boss can reduce the fatigue damage and the deformation risk of main spring, improves the reliability and the life of supporting on the shock absorber. The stable main spring structure can ensure that the hydraulic assembly keeps good performance in the long-term working process, and reduces maintenance and replacement cost caused by main spring failure. The good vibration reduction effect can improve the control stability and the running smoothness of the vehicle. The boss on the main spring can effectively reduce vibration and jolt of the vehicle in the running process, so that a driver can better control the vehicle, and driving safety and comfort are improved. The accurately regulated liquid chamber pressure can enable the upper support of the shock absorber to respond to different road conditions and driving conditions more quickly and accurately, and the control performance of the vehicle is further optimized.
Still further, a shock absorber upper support, including last support frame, set up a plurality of bolt locating holes on the support frame, all coaxial be fixed with a bolt in every bolt locating hole, the upper portion of going up support frame is coaxial to be provided with the open hydraulic assembly mounting groove in top, the coaxial hydraulic assembly that supports on the shock absorber that is provided with in the hydraulic assembly mounting groove, the coaxial support end cover that is fixed with in top of hydraulic assembly mounting groove, the support end cover will hydraulic assembly pressure equipment is fixed in the hydraulic assembly mounting groove.
The upper support bracket is one of main structural components supported on the shock absorber and plays a role in supporting and connecting other components. It is typically made of a high strength metallic material with sufficient strength and rigidity to withstand the various loads during vehicle travel. The upper support bracket is provided with a plurality of bolt positioning holes, and a bolt is coaxially fixed in each bolt positioning hole. These bolts are used to connect the upper support bracket to other parts of the vehicle to ensure a secure and reliable installation of the upper support of the shock absorber on the vehicle. The upper part of the upper support bracket is coaxially provided with a hydraulic assembly mounting groove with an open top. The mounting slot is shaped and sized to mate with the hydraulic assembly for mounting and securing the hydraulic assembly. The hydraulic assembly is a core component supported on the shock absorber and consists of an inner framework, an upper liquid chamber, a lower liquid chamber, a liquid inlet runner, a connecting runner, damping liquid, a main spring, an upper leather bag, a lower leather bag and the like. The hydraulic assembly is used for absorbing and consuming vibration and impact energy in the running process of the vehicle through the flowing and deformation of damping fluid, so that the purpose of vibration reduction is achieved. The hydraulic assembly is arranged in the hydraulic assembly mounting groove and is coaxially arranged with the upper support bracket. Therefore, the hydraulic assembly can be ensured to stably play a role in the working process, and the hydraulic assembly is convenient to install and maintain. The bracket end cover is positioned at the top of the hydraulic assembly mounting groove and is coaxially fixed with the upper support bracket. The hydraulic assembly is pressed and fixed in the hydraulic assembly mounting groove, so that the hydraulic assembly is prevented from loosening or displacing in the working process. The bracket end caps are typically made of a metallic material that has sufficient strength and rigidity to withstand the pressures and external loads of the hydraulic assembly. The fixing mode between the upper support bracket and the upper support bracket can adopt the modes of bolt connection, welding and the like, so that firm and reliable connection is ensured. The upper support bracket serves as the main structural component of the upper damper support and serves the important task of connecting the upper damper support to other vehicle components. Its strength and rigidity directly affect the stability and reliability of the mounting of the support on the shock absorber. The arrangement of the bolt positioning holes and the bolts enables the upper support bracket to be firmly connected with other parts of the vehicle. The connecting mode can ensure that the upper support of the shock absorber cannot loosen or fall off in the running process of the vehicle, and ensure the running safety of the vehicle.
Still further, a mounting structure of supporting on shock absorber includes the shock absorber, the lower extreme and the wheel of shock absorber are fixed, the upper end of shock absorber is fixed with above-mentioned supporting on the shock absorber, a plurality of the top of bolt passes the automobile body and can dismantle through the nut and be fixed in on the automobile body.
The damper plays a key role in the whole mounting structure. The lower end of the vibration-reducing device is fixed with the wheels, so that the vibration generated by the wheels in the running process can be effectively reduced and transmitted to the vehicle body. The damper is generally composed of a spring for absorbing vibration energy and a damper for controlling a rebound speed of the spring so that the vehicle travels more smoothly. The upper end of the shock absorber is fixedly provided with an upper shock absorber support, and the shock absorber is connected with the vehicle body in a connecting mode, so that the supporting and vibration reduction effects on the vehicle body are realized. As previously mentioned, the upper damper support includes the upper support bracket, the hydraulic assembly, and the bracket end cap. The mounting platform is provided for the shock absorber and is connected with a vehicle body through bolts. The design and performance of the support on the damper directly affects the damping effect and reliability of the overall mounting structure. The upper support bracket is provided with a plurality of bolt positioning holes and bolts, wherein the bolt positioning holes and the bolts on the upper support bracket are used for fixing the upper support of the shock absorber on the vehicle body. The tops of the bolts penetrate through the vehicle body and are detachably fixed through nuts, so that the installation and the maintenance are convenient. The vehicle body is a main body structure of the entire vehicle, and receives various loads of the vehicle. The upper support of the shock absorber is fixed on the vehicle body through bolts and nuts, and the acting force of the shock absorber is transmitted to the vehicle body, so that vibration and jolt in the running process of the vehicle are reduced. The mounting structure connects the damper with the vehicle body to form a complete damping system. The upper support of the shock absorber is used as an intermediate link of connection, and plays roles of transmitting force and damping. The vibration damper can uniformly transfer the vibration damping force generated by the vibration damper to the vehicle body, reduce vibration and jolt of the vehicle body, and improve the travelling comfort and stability of the vehicle. Meanwhile, the detachable fixing mode enables installation and maintenance to be more convenient. When the shock absorber or the upper support of the shock absorber needs to be replaced, the bolts and nuts can be easily disassembled for maintenance and replacement. Good support mounting structure on the shock absorber can improve the performance of the vehicle. The vibration and jolt of the vehicle in the running process can be reduced, and the operability and stability of the vehicle are improved. Meanwhile, the abrasion of parts of the vehicle can be reduced, and the service life of the vehicle is prolonged. In addition, the installation structure can reduce noise in the running process of the vehicle and improve riding comfort of the vehicle. When the vehicle is driven on an uneven road surface, vibrations and shocks are generated from the wheels. These vibrations and shocks are transmitted through the damper to the support. The hydraulic assembly in the upper support of the shock absorber absorbs and dissipates vibration and shock energy through the flow and deformation of the damping fluid. Meanwhile, elastic components such as a main spring, an upper leather bag, a lower leather bag and the like can also provide certain elastic support, so that the vibration reduction effect is further improved. The upper damper support transmits the forces generated by the damper to the vehicle body, and distributes and receives these forces through the structure and strength of the vehicle body. Meanwhile, the vehicle body can also feed back a part of force to the upper support of the shock absorber, so that a dynamic balance system is formed. The upper support of the shock absorber is fixed on the vehicle body through the bolts and the nuts, so that the stability and the reliability of the whole installation structure are ensured. During running of the vehicle, the bolts and nuts are required to withstand various forces from the shock absorber and the vehicle body, and thus are required to have sufficient strength and tightening force.
The invention has the beneficial effects that the inner framework is used as a core supporting structure of the whole hydraulic assembly, and provides a basis for installing and fixing other parts. The upper liquid chamber and the lower liquid chamber are respectively positioned at the upper side and the lower side of the middle part of the inner framework and are coaxially arranged. They are the main space for storing damping fluid in the hydraulic assembly and are communicated with each other through the connecting flow channels. The liquid inlet channel is arranged in the inner framework and is communicated with the liquid feeding chamber, and the liquid inlet is blocked. The function of the liquid inlet flow channel is to inject damping liquid into the liquid feeding chamber in the assembly process of the hydraulic assembly. Once the injection is completed, the inlet is blocked to prevent leakage of the damping fluid. The connecting runner is also arranged in the inner framework and communicates the upper liquid chamber with the lower liquid chamber, so that damping liquid can flow between the two liquid chambers. The liquid inlet flow passage, the liquid feeding chamber, the connecting flow passage and the liquid discharging chamber form a closed space capable of generating elastic deformation. The damping fluid is ensured not to leak in the working process, so that the stability and the reliability of the upper support of the shock absorber are ensured. When the upper support of the shock absorber receives vibration and impact from a road surface in the running process of the vehicle, the closed space can be correspondingly deformed, so that damping liquid flows between the liquid chambers to generate damping force, and the shock absorber has a shock absorbing effect.
In summary, the hydraulic assembly supported on the shock absorber designed by the invention can effectively improve the performance and reliability of the support on the shock absorber through the unique structural design and the action of damping fluid, has good damping performance, performs vibration reduction through a hydraulic mode, replaces the vibration reduction function of a rubber main spring, has the advantages of difficult aging, high strength and good wear resistance, is insensitive to temperature based on the hydraulic vibration reduction of the damping fluid, and provides more comfortable and stable driving experience for a vehicle based on the support on the shock absorber designed by the hydraulic assembly and the mounting structure thereof.
