A power transmission device between a car engine and a driving wheel. Ensure that the car has the required traction, speed, and coordinated changes between them under various driving conditions. It is a vehicle with good power and fuel economy. Adapt to differential requirements, and enable power transmission to be smoothly engaged or completely and quickly separated according to demand.
The transmission system includes clutches, transmissions, universal transmissions, main reducers, that is, differentials, axles, and other components.
The drive train can be divided into the mechanical drive, hydraulic drive, hydraulic drive, electric drive, etc. according to the different energy transmission methods.
Mechanical drive train
Front, longitudinal, front-wheel drive arrangement
The engine is front, longitudinal, and front-wheel drive so that the transmission and the final reducer are connected, eliminating the universal transmission between them.
Typical hydromechanical transmission
1-Hydraulic torque converter 2-Automatic transmission 3-Universal drive 4-Drive axle 5-Main reducer 6-Drive shaft
Hydrodynamic transmission (here referred to as hydrodynamic transmission) uses the change of kinetic energy during the circulating flow of the liquid medium between the driving element and the driven element to transmit power. The hydraulic transmission is connected with a stepped mechanical transmission in series. Such transmission is called a hydraulic mechanical transmission.
Hydrostatic drive train
1-Clutch 2-Oil pump 3-Control valve 4-Hydraulic motor 5-Drive axle 6-Oil pipe
Hydraulic transmission is also called hydrostatic transmission, which transfers energy through the change of static pressure energy of liquid transmission medium. It is mainly composed of an engine-driven oil pump, hydraulic motor, and control device.
