The invention relates to a hydrodynamic drive system for a mine car, which comprises an engine, a gear-shifting clutch and a mechanical speed changing box as well as an elastic plate, a hydrodynamic torque converter, a shell and a turbine shaft, wherein the output end of the engine is fixedly connected with the flexible plate, the output end of the turbine shaft is connected with the mechanical speed changing box, and the hydrodynamic torque converter is arranged in a working cavity formed by the elastic plate, the shell and the turbine shaft; and a torsional damper and a lockup clutch are arranged in a cover vortex working cavity formed by a cover wheel, a turbine body and a turbine hub, one end of the torsional damper is fixed on the turbine hub, the other end of the torsional damper is connected with the lockup clutch by a spine, and the other end of the lockup clutch is connected with the cover wheel by a spine. The hydrodynamic drive system solves the technical problem of higher car price caused by a conventional expensive automatic speed changing box with the hydrodynamic torque converter. The hydrodynamic drive system is additionally provided with the hydrodynamic torque converter so that the connection of the engine and the mechanical speed changing box is changed to be flexible connection, the clutch is protected, and then a torque is increased.
Description
Technical field [0001] The invention relates to a hydraulic transmission system, in particular to a hydraulic transmission system for a mine car with a hydraulic torque converter, and belongs to the mechanical field. Background technique [0002] At present, the transmission system on the minecart is divided into two structures. One is the minecart with the transmission system of the road vehicle chassis and mechanical gearbox, that is, the engine is directly connected to the mechanical gearbox, and the other is under the condition of unchanged chassis. , Adopt full hydraulic automatic transmission, that is, the engine is connected with full hydraulic automatic transmission. The first is that due to the rigid connection between the engine and the mechanical gearbox, the minecart is generally heavily loaded uphill, and the road conditions are complex, requiring frequent gear changes, which causes the gear shift clutch and gearbox to be damaged due to the impact of frequent shifts....
