Description

Automobile brake energy storage-energy release driving device and method

technical field

The invention relates to the technical field of automobile energy saving, in particular to an automobile brake energy storage-energy release drive device and method.

Background technique

The automobile industry started in 1885 when the Germans Daimler and Benz assembled the internal combustion engine on a tricycle and developed to today. An ordinary car is composed of tens of thousands of parts, and its power, transmission, suspension, steering, braking, electrical appliances, and body systems are all modern technologies. For example, the mechanical transmission in the transmission system, through the combination and matching of various gears, realizes the mutual transformation of the vertical axis and the horizontal axis, the transformation of high speed and low speed and the magnitude of torque, the transformation of the direction of motion, and the mutual transformation of one group and multiple groups of rotation... It can Transformation and kinetic energy transfer from a simple motion mode to a complex motion mode according to design requirements. The central controller in the electrical system takes the computer as the core, and the "Controller Area Network-BUS" (Controller Area Network-BUS), which was first applied to aircraft, participates in the data transmission of sensors all over the body, which can easily realize precise control of driving and safety functions.

But the automobile industry is facing increasingly serious problems of energy saving and emission reduction. When a car is braked or decelerated by traditional technology (such as brake drum or brake disc, frictional heat is generated), part of the kinetic energy is converted into heat energy and dissipated. How to store and reuse this part of kinetic energy, and to explore new energy and clean energy as vehicle power has become a hot topic.

Hybrid vehicles came into being, especially electric hybrid vehicles have begun to be put into commercial production. Then a key technology, the power compound device, came out. The power combination device makes the vehicle engine "composite" with another new power (for electric hybrid vehicles, it refers to the vehicle engine and electric motor or generator/motor "combination"), so that the vehicle can be powered by the engine and the new power The power is jointly driven or driven separately.

Electric hybrid vehicles have made some progress in terms of energy saving and emission reduction, but there are many problems: (1) In addition to the vehicle engine, its power system needs to add generators, storage batteries, motors or generators/motors, which occupy a relatively large portion of the vehicle. Large space and weight; (2) The electric energy of the storage battery comes from the external energy source and the on-board engine, which still consumes energy and fuel to a considerable extent; (3) The efficiency in recovering and utilizing the kinetic energy lost when the car brakes and decelerates is limited, Because a) If a special on-board generator is used to "collect" the electric energy generated by the wheel rotation (cutting the magnetic field line) during braking and deceleration and store it in the storage battery, and then use another special on-board motor to start the car, When accelerating, the electric energy obtained from the battery drives the wheels to rotate, and the on-board equipment is more and heavier; b) If a so-called generator/motor is used to complete the above-mentioned work of both generating and driving, although the generator and the motor are theoretically reversible, their The structure is also basically the same, but because of their different tasks and specific requirements, in actual structure, if a well-designed generator is used as a motor, the efficiency is low, and conversely, if a well-designed motor is used as a generator, the efficiency is also low; c) power generation The machine converts mechanical energy into electrical energy, which is input and stored in the battery, then output from the battery, input to the motor, and then converts electrical energy into mechanical energy. The energy loss in the conversion process is large.

In addition, there are also some schemes that try to apply hydraulic pneumatic transmission technology to store and utilize the kinetic energy lost when the above-mentioned automobile brakes and decelerates. Relevant designs often include a series of hydraulic and pneumatic components and circuits that cooperate with each other in this field, which is difficult to actually layout and apply in the limited space of the car.

(3) Beneficial effects

The accumulator circuits in the hydraulic transmission system include spring type, weight type and gas type. Among the gas type, piston type and air bag type are more widely used, and they are all driven by liquid, that is, hydraulic pressure (usually oil pressure).

The spring cylinder of the device of the present invention combines spring type and gas type hydraulic accumulator technologies, so that the pressure potential energy of the compressed gas is superimposed on the spring force potential energy, increasing the stored and released energy without significantly increasing the volume of the cylinder; wherein the helical spring is used as the rubber bladder The skeleton supports and maintains the shape of the rubber bladder, reduces the friction between the bladder and the inner wall of the cylinder, and prolongs its service life.

Moreover, the device of the present invention does not need to be driven by liquid hydraulic pressure, and is directly driven by two gears-double-sided tooth column-piston, which eliminates many hydraulic transmission components and pipelines, reduces the volume, weight and production cost of the equipment; in addition, the hydraulic transmission system is driven by hydraulic pressure. The accumulator usually needs "oil port" to be placed vertically downwards, but the device of the present invention has no "oil port" and is easy to install.

The storage and release volume of the device in the present invention is related to the length of the cylinder, the area of the piston, the initial pressure and degree of compression of the gas medium, and the elastic coefficient of the compression spring. If only the contribution of the compressed gas to the storage and release volume of the device (set as W) is used for approximate calculation, the initial length of the gas medium in the cylindrical cylinder is l, the initial pressure of the gas medium in the cylinder is p, and the gas The length of the compressed medium in the cylindrical cylinder is x, and the area of the piston is s, then $W={\∫}_x^l\mathrm{sp}\frac{l}{x}\mathrm{dx}.$

The mutual collocation and optimization of these parameters enable the storage and release of the device to adapt to the storage and release of energy within a certain range of braking-starting, deceleration-acceleration during the operation of the car. According to the design requirements, two or more devices can be used; and if necessary, it can be adapted to the traditional braking technology or combined with the power of the automobile engine; with the advancement of material science and technology, the pressure that the cylinder can withstand is constantly changing. Improve, refer to the pressure that the gas accumulator of hydraulic transmission can withstand. For example, the TOBUL airbag accumulator has reached 7500PSI (51.8Mpa), and the piston accumulator has reached 10000PSI (69Mpa). Raise the outlook for optimism.

The basic principle of the device of the present invention is based on pneumatic transmission, and has the common characteristics of pneumatic transmission. It is safe and reliable to work under certain conditions, with simple structure, light weight, easy installation and maintenance, and low cost.

The operation of the device of the invention can use a brake pedal and an accelerator pedal, and basically retains the traditional driving method of the automobile.

The device of the present invention participates in the braking and deceleration of emission-free automobiles, during which energy recovery is stored as gas pressure potential energy and spring elastic potential energy; when necessary, the stored potential energy is released and converted into kinetic energy to drive the vehicle to start, Accelerate, and effectively realize vehicle energy saving and emission reduction.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment one:

As shown in Fig. 1, Fig. 5 and Fig. 6, this embodiment records an automobile brake energy storage-energy release driving device 34, including:

The spring cylinder 1 includes a cylinder wall 12 forming a cylinder cavity, a piston 14 that is slidably engaged with the inside of the cylinder wall 12, and a spring that is connected between the piston 14 and the end of the spring cylinder 1 and whose direction of elasticity is parallel to the sliding direction of the piston 14. A coil spring 8, a gas medium 2 is arranged in the cylinder cavity;

The translation part 38 includes one end connected to the piston 14, a double-sided tooth column 3 with rack slots 9 respectively distributed on opposite sides along the sliding direction, and accommodating the double-sided tooth column 3 to slide therein The translation part shell 27;

The rotating part 39 is two gears 10 and 11 that mesh and match with the rack groove 9 corresponding to the double-sided tooth column 3 from opposite sides, and the two gears 10 and 11 are connected to the transmission shaft of the automobile through the input transmission system 6 respectively. 33—the wheel 37 is connected to the rotation braking system, and is connected to the hybrid power device 35 through the output drive system 7 .

In this embodiment, an air charging valve 13 communicating with the cylinder cavity is provided outside the cylinder wall 12 of the spring cylinder 1 . The gas medium 2 can be charged into the spring cylinder 1 through the charging valve 13 .

As shown in FIG. 1 , in this embodiment, the cylinder wall 12 of the spring cylinder 1 is cylindrical, made of a material that can withstand high pressure, and has a smooth inner surface. The inflation valve 13 is arranged on the end of the cylinder wall 12 away from the translation part 38 , and the two ends of the coil spring 8 are respectively fixed on the end of the cylinder wall 12 with the inflation valve 13 and the piston 14 . The coil spring 8 is a compression spring (compression spring) that can withstand axial pressure. There is a certain gap between the coils of the coil spring 8 and the pitch is equal. The load means that when the piston 14 is pushed toward the inside of the cylinder, the gap between the 8 coils of the coil spring can become smaller, and it is compressed and deformed to store deformation energy, that is, elastic potential energy; when the coil spring 8 is compressed While deforming, the volume of the gas medium 2 in the spring cylinder 1 can be compressed and simultaneously reduced, and the pressure of the gas medium 2 increases inversely proportional to the volume reduction of the gas medium 2, thereby storing pressure potential energy .

Figure 2 shows another situation of the embodiment of the present invention, the spring cylinder 15 also includes a rubber bladder 17 built in the cylinder cavity, the gas medium 2 is arranged in the rubber bladder 17, and the coil spring 16 is supported on the outer periphery of the rubber bladder 17. The rubber bladder 17 is made of rubber with excellent elasticity and can withstand volume changes within a certain range. One end of the rubber bladder 17 is a fixed end and communicates with the inflation valve 13. The gas medium 2 such as nitrogen is filled into the bladder 17 under pressure, and the other end of the rubber bladder 17 is a movable end 18 abutting against the piston 19 . When the coil spring 16 is compressed and deformed by an axial external load to store deformation energy, that is, elastic potential energy, the rubber bladder 17 changes synchronously with it, and the volume of the rubber bladder 17 shrinks to store gas pressure potential energy. The standard of the spring cylinder 15 piston 19 seals of the rubber bladder 17 and the requirements on the surface finish of the cylinder can be relatively low, and the cost can be reduced.

In the embodiment shown in Figures 1 and 2, the double-sided tooth column 3 is a long column with rack grooves 9 engraved longitudinally on the upper and lower sides, and the cross section is approximately square. Longitudinal across the full length of its upper and lower midlines; the double-sided tooth column 3 is made of solid material (such as light metal), which can push the pistons 14, 19 to move in the spring cylinders 1, 15, or vice versa. The pistons 14 , 19 push them outwards of the spring cylinders 1 , 15 .

A first guide bracket 25 and a second guide bracket 24 are respectively provided on the inner side of the cylinder wall 12 and the translation part housing 27 to slide and cooperate with the smooth position on the side of the double-sided gear column 3 .

The translation part casing 27 is continuous with the shield 28 provided outside the two gears 10 and 11 .

As shown in Figures 1 and 2, the translation part housing 27 is continuous with the spring cylinders 1 and 15 and is also cylindrical; The part and its two side surfaces are smooth planes coated with lubricant, and the friction force with the first guide bracket 25 and the second guide bracket 24 is very small when it moves in translation under the force parallel to its longitudinal direction.

The other end of the double-sided tooth column 3 is provided with a stop end 20 whose radial width is larger than that of the double-sided tooth column 3, and the end of the stop end 20 is provided with a buffer and shock absorbing device 21, and the translation part The inner wall of the casing 27 is provided with a controllable blocking mechanism 22 that cooperates with the stop end 20 . There are several controllable blocking organs 22 segmentally distributed along the sliding direction, and the controllable blocking organs 22 can block or release the translational movement of the stop end 20 to the outside of the spring cylinders 1 and 15 . As shown in Figures 1 and 2, the controllable blocking mechanism 22 is a wedge-shaped inclined plane facing away from the spring cylinders 1, 15. When the double-sided tooth column 3 moves toward the spring cylinders 1, 15, it can pass through the controllable blocking mechanism 22 When the double-sided tooth column 3 moves away from the spring cylinder 1, 15, the end face of the controllable blocking mechanism 22 facing the spring cylinder 1, 15 side can be blocked at the end of the stop end 20 of the double-sided tooth column 3 , the stopping end 20 cannot be released until the controllable blocking mechanism 22 is controlled to retract.

In this embodiment, the housing 27 of the translation part is provided with several reinforcing ribs 26 , and the controllable blocking mechanism 22 is arranged on the reinforcing ribs 26 . In this embodiment, the reinforcing ribs 26 are light metal beams, which are used to reinforce the longitudinal structure of the cavity wall of the housing 27 of the translation part.

In this embodiment, the end 23 of the translation part housing 27 is made of solid material and is fixedly connected with the end of the light metal beam of the reinforcing rib 26, which is enough to make the stop of the double-sided tooth column 3 Translational movement of the tip 20 towards the outside of the cylinder is prevented here. The rest of the translation part housing 27 is a light and thin plate with some air filtering gaps, which protects and prevents dust from the double-sided tooth column 3 longitudinally translating in the translation part housing 27 .

As shown in Figures 3 and 4, gears 10, 11 are arranged above and below the double-sided tooth column 3 at the outer edges of the translation part housing 27 adjacent to the spring cylinders 1, 15, facing each other from top to bottom. The two sides of the double-sided gear column 3 are meshed with the rack groove 9 above and below, so that the upper and lower gears 10, 11 are relatively reversed at the same time (one is clockwise and the other is counterclockwise). Pushing the double-sided tooth column 3 to passively translate, otherwise the active translation of the double-sided tooth column 3 can also push the upper and lower gears 10, 11 to passively rotate accordingly. Because one of the effects of the double-sided tooth column 3 is equivalent to a "piston rod" to push the pistons 14, 19 to move in translation in the cylinder, and the force direction of the "piston rod" can only be parallel to the longitudinal direction of the "piston rod". It should not be subjected to unbalanced force from the vertical direction on one side of the "piston rod". Therefore, the meshing mechanism 5 of the two gears of the present invention-double-sided gear column is different from the usual rack-and-pinion mechanism. Usually, the rack-and-pinion mechanism rotates on one side. The gear meshes with a toothed rack from one side to drive the rack to move. In the present invention, the upper and lower gears 10, 11 engage the double-sided tooth column 3 from opposite sides, so that the double-sided tooth column 3 As a "piston rod", the force received from the vertical direction of the "piston rod" cancels each other out, and the direction of the resultant force of the co-rotation of the upper and lower gears 10, 11 as described above is the same as that of the two gears used as the "piston rod". The face tooth columns 3 are longitudinally parallel.

Therefore the characteristics of the meshing mechanism 5 of the double gear-double-sided tooth column of the present invention are that the upper and lower two gears 10, 11 are relatively engaged with the rack groove 9 of the double-sided tooth column 3 up and down, which is also described The active rotation of the upper and lower gears 10, 11 pushes the double-sided tooth column 3 to passively translate, and the active translation of the double-sided tooth column 3 pushes the structural basis for the passive rotation of the upper and lower gears 10, 11. The coordinated rotation of the upper and lower gears 10, 11 that can push the double-sided tooth column 3 toward the passive translation 30 in the spring cylinder 1, 15 is called "energy storage rotation" 29, and the double-sided gear The column 3 moves toward the outside of the spring cylinder 1, 15 to translate 31 to push the upper and lower gears 10, 11 to rotate passively and correspondingly, which is called "energy release rotation" 32; when the upper and lower gears 10, 11 "energy storage rotation" 29 to push the double-sided tooth column 3 to translate 30 toward the spring cylinder 1, 15, and then push the piston 14, 19 to move into the cylinder to compress the coil springs 8, 16 and the The gas medium 2 increases the potential energy (spring force potential energy and gas pressure potential energy) in the spring cylinders 1 and 15. The inside is blocked by the controllable blocking mechanism 22 and cannot translate to the outside of the cylinder, and the potential energy (spring force potential energy and gas pressure potential energy) is stored in the spring cylinder 1, 15, that is, the upper and lower gears 10, 11 "energy storage rotation" 29 kinetic energy is converted into the potential energy (spring elastic potential energy and gas pressure potential energy) and stored; The spring cylinders 1 and 15 are released by the external translation 31, and the spring force and the pressure of the compressed gas medium 2 in the spring cylinders 1 and 15 push the pistons 14 and 19 and the double-sided tooth column 3 to the spring cylinder 1 , 15 external translation 31, and then promote the upper and lower two gears 10,11 to do the corresponding rotation called "release energy rotation" 32, that is, the potential energy stored in the spring cylinder 1,15 is converted into the Up and down two gears 10,11 " release energy and rotate " 32 kinetic energy.

As shown in Fig. 3, Fig. 4, Fig. 5, and Fig. 6, the input transmission system 6 is a mechanical mechanism that causes the "energy storage rotation" 29 of the upper and lower gears 10, 11 from the rotation of the automobile wheel 27 and the transmission shaft 33. Transmission system, this transmission system is also called brake energy storage transmission system, because the rotation of the vehicle wheel 27 and the transmission shaft 31 through this transmission system causes the "energy storage rotation" of the upper and lower gears 10, 11 29, and then push the double-sided tooth column 3 and the piston 14, 19 to move into the spring cylinder 1, 15 to compress the coil spring 8, 16 and the spring cylinder 1, 15 as described above. The gas medium 2 increases and stores the potential energy (spring force potential energy and gas pressure potential energy) in the spring cylinders 1 and 15, while the kinetic energy of the vehicle wheels 27 and the transmission shaft 33 is reduced, and the vehicle brakes and decelerates , the device 34 of the present invention thus participates in the process of automobile braking, deceleration and energy storage; the above-mentioned functions of the input transmission system 6 are properly integrated with the automobile brake pedal through a computer automatic control system, so that it can be controlled by the automobile brake pedal Stepping on the control, so that when the car needs to brake or decelerate, the stroke of the brake pedal of the car is converted into an electrical signal and input to the central controller, and the computer sends it to the "bus" ("controller LAN bus technology"). analysis and calculation of various driving data, and issue corresponding instructions to the input transmission system 6 .

The output transmission system 7 is a transmission system from the upper and lower gears 10, 11 "energy release rotation" 32 to the vehicle hybrid power device 35. This transmission system is also called the energy release drive transmission system, because the energy stored in the The potential energy (spring force potential energy and gas pressure potential energy) in the spring cylinder 1, 15 is released and converted into the kinetic energy of the upper and lower gears 10, 11 "release energy rotation" 32 as a kind of power through this transmission System 7 is imported into described automobile hybrid device 35, and then realizes that automobile starting, acceleration are jointly driven by automobile engine 36 and described automobile brake energy storage-energy release driving device 34 or are driven separately by one of them, the device of the present invention 34 so as to participate in the process of starting, accelerating and energy release of the car; the above-mentioned functions of the output drive system 7 are properly integrated with the accelerator pedal of the car through the computer automatic control system, so that it can be controlled by stepping on the accelerator pedal of the car, so that when the car needs to start, When accelerating, the stroke of the accelerator pedal of the car is converted into an electrical signal and input to the central controller, and the computer analyzes and calculates various driving data sent to the "bus" ("controller LAN bus technology"), and the output drive System 7 issues corresponding instructions.

As shown in Fig. 1, Fig. 2, Fig. 5, and Fig. 6, the upper limit of how much energy the device of the present invention can store and release is called the amount of storage and release of the vehicle brake energy storage-energy release drive device 34. The energy storage-energy release driving device 34 stores and releases the size of the spring cylinder 1, 15, such as the length and inner diameter of the cylinder (that is, the area of the piston 14, 19), the initial pressure of the gas medium 2 and the degree of compression, the screw The elastic coefficients of the springs 8 and 16 are related to each other, and the mutual matching and optimization of these parameters are compatible with the design requirements of the car; because a large number of braking-starting, deceleration-acceleration in the running of the car is within a not very large range of energy changes Repeat, such as braking from a speed of 50 km/h, decelerating to zero speed, starting from zero speed, accelerating to a speed of 50 km/h, and decelerating from a speed of 70 km/h to 50 km/h Then accelerate from the speed of 50 km/h to the speed of 70 km/h, etc., a car brake energy storage-release driving device 34 with a small amount of storage and release can complete such repeated braking Energy storage-energy release drive, effective energy saving and emission reduction, and does not significantly increase the weight and cost of the vehicle; usually there is no need to demand that the vehicle braking energy storage-energy release drive device 34 has a large amount of storage and release, which is capable of storing all vehicles Kinetic energy "lost" during braking, deceleration and release of all "gained" kinetic energy during start-up and acceleration of the vehicle, because in some cases the energy required to be stored or released exceeds that of the vehicle's brake energy storage-release drive In the case of 34 storage and release, the traditional braking technology of the automobile can be added to the braking and deceleration process of the automobile, or the power of the automobile engine 36 can be added to the starting and accelerating process of the automobile; The storage and release amount of the driving device 34 can be adjusted to increase the storage and release amount of the single vehicle brake energy storage-energy release drive device 34, or use two or more of the vehicle brake energy storage-energy release to drive device34.

The vehicle brake energy storage-energy release driving device 34 is under the control of the vehicle computer central controller and the "controller LAN bus technology", its own components work in coordination and cooperation, and work in coordination with various systems of the vehicle.

Embodiment two:

This embodiment records a vehicle brake energy storage-energy release driving method of the above-mentioned device, including the following steps:

When the car brakes and decelerates, the car transmission shaft-wheel rotation causes the two gears of the car brake energy storage-energy release driving device to rotate in the first rotation direction 29 through the input transmission system, and the two gears and the double-sided gear column of the translation part The meshing makes the double-sided tooth column of the translation part drive the piston 14, 19 to translate 30 in the first direction, compress the gas medium 2 of the spring cylinder 1, 15 and the coil spring 8, 16, so that the device stores energy, and at the same time, the automobile system Slow down;

When the car starts to accelerate, the compressed gas medium 2 in the spring cylinders 1, 15 and the coil springs 8, 16 release energy and expand, so that the pistons 14, 19 drive the double-sided tooth column of the translation part to the opposite direction to the first direction The second direction of translation 31, the meshing of the two gears and the double-sided gear column of the translation part makes the two gears rotate in the second rotation direction 32 opposite to the first rotation direction, and then transmits the rotational kinetic energy to the hybrid through the output transmission system. The power unit 35 provides power for starting and accelerating the automobile.

Wherein, the vehicle brake pedal or vehicle accelerator pedal is used to complete the control of the vehicle brake energy storage-energy release driving device 34 for braking energy storage or energy release driving.

In this embodiment, the method more specifically includes:
