Description

Technical Field

[0001] The invention belongs to the technical field of power transmission, in particular to a hydraulic impact type power transmission device. Background Art

[0002] The transmission device is an intermediate device that transmits the movement and power of the power machine to the working mechanism. During the transmission process, the torque generated by the engine is transmitted to the drive wheels through the clutch, gearbox, universal joint, drive shaft, final reducer, differential, and half-shaft in sequence. The drive wheels receive the torque and apply a backward force to the ground, thereby causing the ground to produce a forward reaction force on the drive wheels. This reaction force is the driving force of the car. The composition and layout of the transmission system vary with the type of engine, installation position, and purpose of the car.

[0003] However, the power of automobile driving now relies on the torque of automobile engine (motor) to drive the automobile to drive. The torque of automobile engine is combined with clutch and gearbox to control the driving of automobile, such as forward and reverse and shifting during driving. When the clutch and gearbox convert the torque generated by automobile engine into driving power of automobile, now automatic transmission automobile adds many additional functions in automobile clutch and gearbox for the smooth starting and shifting of automobile when driving. These functions will cause many faults in the long-term running-in, such as common faults such as abnormal noise and shaking of gearbox. These functions will also increase the burden of automobile engine and increase the energy consumption of automobile. Now automobile gearbox can only use engine speed to slow down appropriately, but cannot control automobile to slow down and stop when going down long slope or driving.

[0004] At the same time, the car relies on the car's brakes to slow down and stop when going down a long slope or driving; when the car frequently uses the brakes on a long slope, the brake drum (disc) will heat up, causing brake failure, thereby causing various traffic accidents; there is no car that uses the power of the engine to control the car's deceleration and braking (parking) function. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a hydraulic impact power transmission device.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A hydraulic impact power transmission device comprises a housing, a high-pressure liquid tank is arranged at the top of the housing, an impeller is arranged at the bottom of the high-pressure liquid tank, a plurality of injection devices are arranged around the impeller, and the plurality of injection devices are all arranged at the bottom of the high-pressure liquid tank;

[0008] A hydraulic pump and a gear box are respectively arranged on the inner sides of both ends of the bottom of the outer shell, an output shaft is arranged in the gear box, the output shaft passes through the side wall of the gear box and the outer shell, a passive gear is arranged at the inner end of the output shaft, a power shaft is arranged at the bottom of the impeller, a driving gear is arranged at the bottom end of the power shaft, and the driving gear is meshed and connected with the passive gear.

[0009] Preferably, the liquid outlet of the hydraulic pump is connected to the high-pressure liquid tank through a pipeline, and a liquid inlet is provided at the bottom end of the hydraulic pump.

[0010] Preferably, the driving gear and the driven gear are both helical cylindrical gears.

[0012] Preferably, the clockwise nozzle and the counterclockwise nozzle both adopt a downwardly inclined structure with the nozzle opening.

[0013] Preferably, a liquid is provided at the bottom of the shell, and the liquid is antifreeze.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] In the present invention, the hydraulic pump brought by the torque of the automobile engine pumps up the liquid in the hydraulic box and converts it into high-pressure liquid to impact the impeller on the automobile gearbox to work. The higher the speed of the automobile engine, the greater the working flow of the hydraulic pump, and the pressure of the outflowing liquid under the control of the nozzle flow will also increase accordingly. At this time, the flow rate ejected by the nozzle is large and the injection speed is high; at the same time, the impact force will also become greater, and the force received by the impeller will become greater. The present invention has a number of advanced technologies that can increase the power of the engine and reduce the fuel consumption of the automobile; it can also improve the driving safety of the automobile; and it can also use the power of the automobile engine to brake and stop by controlling the rotation direction of the impeller.

[0019] The following is combined with Figure 1-2 , further illustrating a specific implementation of a hydraulic impact type power transmission device of the present invention. A hydraulic impact type power transmission device of the present invention is not limited to the description of the following embodiments.

[0020] Embodiment 1:

[0021] This embodiment provides a specific structure of a hydraulic impact power transmission device, such as Figure 1-2 As shown, it comprises a housing 1, a high-pressure liquid tank 3 is arranged at the top of the housing 1, an impeller 4 is arranged at the bottom of the high-pressure liquid tank 3, a plurality of injection devices 5 are arranged around the impeller 4, and the plurality of injection devices 5 are all arranged at the bottom of the high-pressure liquid tank 3;

[0022] A hydraulic pump 6 and a gear box 7 are respectively arranged on the inner sides of both ends of the bottom of the housing 1. An output shaft 8 is arranged in the gear box 7. The output shaft 8 passes through the side wall of the gear box 7 and the housing 1. A passive gear 10 is arranged at the inner end of the output shaft 8. A power shaft 11 is arranged at the bottom of the impeller 4. A driving gear 12 is arranged at the bottom of the power shaft 11. The driving gear 12 is meshed and connected with the passive gear 10, and the output shaft 8 is connected to the vehicle transmission shaft.

[0023] The liquid outlet of the hydraulic pump 6 is connected to the high-pressure liquid tank 3 through a pipeline, and a liquid inlet 13 is provided at the bottom end of the hydraulic pump 6.

[0024] The driving gear 12 and the driven gear 10 are both helical cylindrical gears.

[0025] The injection device 5 includes a clockwise nozzle 14 for controlling the impeller 4 to rotate clockwise, and a counterclockwise nozzle 15 for controlling the impeller 4 to rotate counterclockwise, both of which are controlled by control valves arranged at the ends thereof.

[0026] The clockwise nozzle 14 and the counterclockwise nozzle 15 both adopt an inclined structure with the nozzle opening facing downward.

[0027] Liquid is arranged at the bottom of the housing 1, and the liquid is antifreeze.

[0028] Working principle: Figure 1-2 As shown, the automobile engine drives the hydraulic pump shaft, the housing 1 and the hydraulic pump 6 are installed together, and the housing 1 is connected to the automobile engine and installed at the rear of the automobile engine. When the automobile engine is working, the hydraulic pump 6 is driven to work through the hydraulic pump shaft. The liquid inlet 13 is the liquid input port of the hydraulic pump 6. When the liquid sucked by the hydraulic pump 6 through the liquid inlet 13 is converted into high-pressure liquid according to the working principle of the hydraulic pump 6, it is input into the high-pressure liquid tank 3 through the liquid outlet of the hydraulic pump 6. The high-pressure liquid inside the high-pressure liquid tank 3 is impacted by the injection device 5 to rotate the impeller 4. The speed of the impeller 4 is controlled by the hydraulic impact force of the liquid output by the hydraulic pump 6;

[0029] In order to ensure the smooth rotation of the impeller 4 and the stable driving speed of the vehicle, the impeller counterweight is increased according to the rotation law of physics. The weight of the impeller 4 can be matched according to the total weight of the vehicle body, and multiple sets of injection devices 5 can be installed correspondingly from the high-pressure liquid tank 3;

[0030] The injection device 5 includes a clockwise nozzle 14 and a counterclockwise nozzle 15. When only one of the nozzles is opened, the impeller 4 is impacted and rotated by the injected high-pressure liquid. When the clockwise nozzle 14 and the counterclockwise nozzle 15 are opened at the same time, the impeller 4 stops rotating. The rotation direction of the power shaft 11 controls the forward and backward movement of the vehicle. When the vehicle needs to slow down and stop during driving, the liquid's counter-impact force is used to force the vehicle to slow down and stop. When emergency braking is required during driving, the counter-impact force is used to perform emergency braking at the same time as braking, which can reduce the braking distance. The size of the impeller 4 can be designed according to the installation position of the gearbox.

[0031] When the power shaft 11 rotates and works, the driving gear 12 installed under the power shaft 11 will run synchronously through the power shaft 11. The driving gear 12 and the passive gear 10 are a group of interlocking gears. At this time, the passive gear 10 will convert the rotation energy of the impeller 4 into the power required for the car to travel through the output shaft 8. The flow rate and pressure of the working liquid water of the hydraulic pump 6 are designed depending on the total weight of the car itself. The flow rate of the injection device 5 is matched by the flow rate required by the hydraulic pump 6 and the high-pressure liquid tank 3 according to the impeller 4. In order to give full play to the power of the car engine, several more groups of interlocking gears can be installed between the passive gear 10 and the output shaft 8. In this way, the gearbox will have high and low gears. Large engineering vehicles can also be designed with high, medium and low gears, using low gear to start and high gear to travel. The gearbox 7, the injection device 5, the impeller 4 and the power shaft 11 are all installed inside the shell 1. When the injection device 5 impacts the impeller 4, the liquid automatically falls into the inside of the shell 1 to complete the internal circulation process.

[0032] The hydraulic impact power transmission device of the present invention can be applied to a series of transportation tools such as automobiles and ships.

[0033] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
