Embodiment Construction

[0058] Such as figure 1 As shown, a mining vehicle hydraulic mechanical transmission system of the present invention includes an engine 101, a purely mechanical gearbox 103, a final reducer 104, and a wheel speed reducer 105, and is characterized in that it also includes a hydraulic transmission system 102 , the engine 101 generates power and enters the hydraulic transmission system 102 to realize the functions of power buffering, switching and speed-up; the power is transmitted to the pure mechanical gearbox 103 to realize the functions of shifting and deceleration and increasing torque; the power is transmitted again The final drive 104 and the wheel reducer 105 are finally transmitted to the tires to drive the vehicle forward.

[0059] The hydraulic transmission system of the present invention includes: a power input part, a torque converter with a lock-up clutch, a speed increasing device, a shift clutch, two pump power output ports and a power output part. The specific s...

Abstract

The invention relates to a vehicle transmission system, in particular to a transmission system with buffer heavy load impact function of an autodumper for mine. A transmission system with the buffer heavy load impact function of the autodumper for mine comprises an input output device, a torque converter with a lockup clutch, a speed increasing device, a shifting clutch and two pump power output orifices. The transmission system is mainly used in the mine vehicle field and adopts electrohydraulic control. Locking up and power switching adopts a wet clutch. The invention has good reliability and can be applicable to the severe environment of mine. The invention has the advantages of buffering the impact of a mechanical gear box on an engine and the whole transmission system in the gear shifting and starting process and realizing low speed high torsion which is required when the vehicle starts. The function of a hydraulic gear box is basically realized but the cost is lower.

Description

technical field [0001] The invention relates to a vehicle transmission system, in particular to a transmission system of a mining dump truck with the function of cushioning the impact of heavy loads. Background technique [0002] The working characteristics of mining dump trucks: heavy load, poor road conditions, frequent gear shifting, long-distance heavy load climbing, and large impact on the transmission system. Only the transmission system with a hydraulic torque converter can meet the requirements; [0003] At present, there is no domestic manufacturer producing hydraulic-mechanical gearboxes suitable for mining vehicles. Imported models are expensive and difficult to meet the relatively large demand of domestic mines. The development of a hydromechanical gearbox suitable for the working conditions of mining vehicles has a long cycle, large investment, and high risks. At present, no enterprise or scientific research institution can undertake it. [0004] At present, th...
