Description

Energy converter, propeller, output device, power transmission mechanism, vehicle and ship

Technical Field

The invention relates to the field of transmission devices, in particular to an energy converter, a propeller, an output device, a stepless speed change power transmission mechanism, a vehicle and a ship, and particularly relates to an energy converter, a shaftless paddle propeller, a stepless speed change power transmission mechanism, a vehicle and a ship.

Background

The current vehicles and ships mainly use traditional petrochemical fuel as power, and the power of an engine is transmitted to a wheel shaft of a driving wheel or a propeller through a transmission system to drive the vehicles or ships to move.

The power of the engine is equal to the product of the torque and then divided by a constant, normally, when the output power of the engine is constant, if the speed of the vehicle or the ship is lower, the rotating speed of the wheels or the propeller is smaller, and the torque is larger; vice versa, the higher the speed of the vehicle or vessel, the higher the rotational speed of the wheels or propellers and the lower the torque. However, in the actual situation, the wheels or propellers are connected with the crankshaft of the engine through a transmission device, the rotating speed of the wheels or propellers is smaller, the rotating speed of the engine is also smaller, the output power of the engine is reduced, finally, the torque cannot be increased, and the engine can be flamed out. Therefore, it is necessary to design the transmission device to have a speed change function, and to change the transmission ratio by the speed change device so that the vehicle or the ship can obtain a good torque under various speeds.

The existing commonly used speed-changing transmission device generally comprises a clutch, a gearbox, a universal joint, a transmission shaft (rear-mounted), a main speed reducer, a differential and other structures, and the devices are mechanically and rigidly connected and have higher transmission efficiency, but the structure is relatively complex, the weight is larger, and the price is also relatively expensive.

The hydraulic transmission system used in industry generally comprises a hydraulic pump, a hydraulic motor, a reversing valve, a pipeline and the like, the motor is driven by utilizing hydraulic pressure to convert and transmit energy, and the hydraulic transmission system has the advantages of small volume, light weight, easy reversing, stepless speed change and the like, but has low transmission efficiency and is generally only used in industrial machinery. The vane pump is a hydraulic pump of a hydraulic transmission system, the vane pumps suck liquid in a mechanical mode, compress the liquid to form pressure, and then push the liquid to flow by a method of discharging the liquid, the flowing speed of the liquid in the vane pump is discontinuous, energy is converted into heat, loss is large, and transmission efficiency is low.

The electric vehicle which has been started in recent years is driven by electric power, a complex variable speed transmission device is omitted, the wheels can be directly driven by a motor through a speed reducer to move, and the electric vehicle has the advantages of small size, light weight, easiness in reversing, stepless speed change and the like, but is influenced by a battery technology and a charging technology, so that the current battery has the defects of large weight, instability, insufficient cruising ability, inconvenience in charging and the like, and is in a preliminary development stage at present.

The displacement of a ship is usually relatively large, and in order to drive the ship to normally sail, the volume and the power of an engine of the ship are also very large, and in addition to the engine, a huge reduction transmission device and a long and huge propeller main shaft penetrating through a ship body are required to be arranged inside a ship cabin with the size of earth. This set of bulky and complex mechanical systems places a heavy mass burden on the vessel and creates significant noise and vibration problems. Therefore, more and more pleasure-boat have adopted electric propulsion system, though its conversion efficiency reduces, nevertheless arrange simply, save valuable cabin inner space, avoid noise and vibration problem simultaneously, bring good comfortable experience for the visitor.

The shaftless propeller structure is a novel ship propulsion technology, generally adopts an electromagnetic driving mode, has the advantages of light structural weight, high propulsion efficiency, low noise and the like, but cannot solve the technical problems of smaller overall dimension and insufficient output power at present due to great technical difficulty.

In view of the foregoing, there is a need for improvements in conventional transmissions.

Referring to the description of fig. 1 and fig. 3A, the transducer 1 further includes a leading blade 161, the leading blade 161 is mounted on the inner wall of the fluid channel 111, and the leading blade 161 extends from the inner wall of the fluid channel 111 into the fluid channel 111. The leading vane 161 is located on the side of the fluid passage 111 into which the fluid flows. That is, the fluid in the fluid passage 111 flows through the leading vane 161 first and then through the vane 13.

One end of the first conduit 43 communicates with an outlet of the fluid passage of the first continuously variable transmission 41, and the other end communicates with an inlet of the fluid passage of the second transducer 42; one end of the second conduit 44 is communicated with the outlet of the fluid passage of the second transducer 42, and the other end is communicated with the inlet of the fluid passage of the first transducer 41.

It is noted that, in the preferred embodiment, the circulation of the fluid in the fluid channels of the first transducer 41 and the second transducer 42 can be realized through the first conduit 43 and the second conduit 44. Preferably, the gear of the first transducer 41 is adapted to be drivably connected to the power input shaft; the gear of the second transducer 42 is adapted to be drivably connected to the power take-off shaft.

For example, when the temperature in the first duct 43 or the second duct 44 is too high, the temperature of the first duct 43 or the second duct 44 is lowered by the temperature adjusting member 45; when the temperature in the first pipeline 43 or the second pipeline 44 exceeds a preset temperature, the temperature of the first pipeline 43 or the second pipeline 44 is reduced through the temperature adjusting piece 45.

It should be noted that the temperature adjusting member 45 can connect an external cooling system with the transducer, and the temperature of the fluid inside the transducer can be controlled by heating or cooling, so that the fluid is in the most effective working temperature range, and the transmission efficiency is improved.

It is understood that the fluid can be injected into the entire continuously variable transmission power transmission mechanism 4 or the fluid can be withdrawn from the entire continuously variable transmission power transmission mechanism 4 through the flow regulating member 46 during the production or maintenance of the continuously variable transmission power transmission mechanism 4.

Referring to fig. 7 of the specification, the continuously variable power transmission mechanism 4 further includes a third transducer 47, a flow divider 481, a flow combiner 482, a third conduit 491 and a fourth conduit 492. The third transducer 47 is the transducer 1 described in embodiment 1 above, and the shunt 481 is mounted to the first conduit 43 and communicates with the first conduit 43; the flow combiner 482 is installed on the second pipe 44 and is communicated with the second pipe 44; one end of the third pipeline 491 is communicated with the flow divider 481, and the other end is communicated with the inlet of the fluid channel of the third transducer 47; one end of the fourth conduit 492 communicates with the outlet of the fluid channel of the third transducer, and the other end communicates with the flow combiner 482.

After the fluid flowing out through the outlet of the fluid channel of the first transducer 41 is split by the splitter 481, a part of the fluid enters the fluid channel of the second transducer 42 through the first pipeline 43, and another part of the fluid enters the fluid channel of the third transducer 47 through the third pipeline 491. The fluid flowing out of the fluid channel of the second transducer 42 and the fluid flowing out of the fluid channel of the third transducer 47 join together through the flow joining device 482 and then enter the fluid channel of the first transducer 41, thereby completing the circulation of the fluid.

It should be noted that in the preferred embodiment, the fluid flowing out from the first transducer 41 passes through the shunt 481 and is divided into two paths, one path enters the second transducer 42 and the other path enters the third transducer 47. It will be appreciated that in other preferred embodiments of the present invention, the fluid passing through the first transducer 41 can be divided into more branches to operate more transducers.

With reference to fig. 8 of the specification, further, the continuously variable transmission power transmitting mechanism 4 further includes a direction changing valve 483, the direction changing valve 483 communicates with the first pipe 43, the direction changing valve 483 also communicates with the second pipe 44, and the flow direction of the fluid in the first pipe 43 and the second pipe 44 can be adjusted by the direction changing valve 483.

It should be noted that, when the power input device connected to the first transducer 41 can realize forward and reverse rotation of itself, the setting of the reversing valve 483 can be eliminated, so as to further simplify the piping and equipment, reduce the resistance and distance of fluid flow, reduce energy loss, and improve the transmission efficiency of the transducer.

It should be pointed out that the continuously variable transmission mechanism 4 provided by the invention performs power transmission by flowing fluid in a closed loop, the power input end and the output end are in soft connection, so that the problem that the rotating speed of the power output end can influence the rotating speed of the input end and further influence the output power of an engine due to the hard connection of a conventional transmission device is solved, and the fact that the rotating speed and the torque of the power output end are really in inverse proportion through the continuously variable transmission mechanism 4 under the condition that the output power of the engine is constant is realized, namely, the lower the rotating speed of the power output end is, the larger the torque is, the larger the driving force is, and the change of the power of the engine is not influenced; as the speed of the engine increases, the rate of fluid flow in the first transducer 41 increases, the greater the pressure on the blades of the second and

third transducers

42, 47, the greater the output torque, and the greater the acceleration of the vehicle. When the vehicle speeds up, the rotating speeds of the blades of the second transducer 42 and the third transducer 47 are correspondingly increased, the output torque is reduced until the acceleration disappears, the rotating speeds and the torques of the blades of the second transducer 42 and the third transducer 47 reach a balanced state, namely, the rotating speed and the torque of each output power of the engine correspond to a balanced relation of a pair of rotating speed and torque, and when the accelerator is stepped on to increase the rotating speed of the engine and increase the output power, the stepless speed change power transmission mechanism 4 can automatically adjust to increase the vehicle to the corresponding running speed, so that the real stepless speed change is realized. Since the fluid flows in a closed loop among the first transducer 41, the second transducer 42, and the third transducer 47 of the continuously variable transmission mechanism 4, the fluid flows smoothly with small flow rate variation, and thus the energy loss of the flow is small and the transmission efficiency is high. According to the characteristics of fluid flowing in the pipeline, the smaller the viscosity of the fluid, the shorter the stroke, the larger the inner diameter of the pipeline and the smoother the pipe wall, the smaller the energy loss of the flowing is, so in order to further improve the transmission efficiency of the stepless speed change transmission device, under the condition of ensuring normal functions and performances, the pipeline inner diameters of the first pipeline 43, the second pipeline 44, the third pipeline 491 and the fourth pipeline 492 are increased as much as possible, the pipeline loop is shortened, the smooth and smooth pipeline inner wall is adopted, and the fluid with smaller viscosity is used, so that the energy loss of the fluid is reduced, and the higher transmission efficiency is obtained.

When the vehicle runs at high speed and needs braking, the engine can be decelerated by releasing the throttle, the rotating speed of the blade 13 forming the first transducer 41 is lower than the rotating speed of the second transducer 42 and the third transducer 47, so that the blade 13 of the first transducer 41 forms resistance to fluid flow and makes the flow disturbed, energy is consumed, the effect of assisting deceleration of the vehicle is achieved, the abrasion of a main braking system of the vehicle is reduced, and meanwhile, the damage of the engine braking to the engine is reduced to the minimum. The whole stepless speed change power transmission mechanism 4 has a very simple structure, complex systems such as gear sets, clutches and the like in the traditional speed change transmission device are eliminated, the structural weight of the whole speed change transmission device is reduced, and meanwhile, the production cost and the use and maintenance cost are reduced.
