Technical Field

Technical Field
The hydraulic torque converter is one kind of hydraulic transmission part, and consists of pump wheel, turbine wheel and guide wheel, and can convert the mechanical energy from the driving shaft into the kinetic energy of liquid for the turbine wheel to work. The hydraulic transmission is arranged between an engine and a transmission, takes hydraulic oil as a working medium, and plays roles in transmitting torque, changing speed and clutching; the pump wheel is driven by the engine to rotate, and liquid is pushed to rotate around the axis of the pump wheel along with the pump wheel, so that the pump wheel obtains certain speed and pressure; the main disadvantages of the traditional hydraulic torque conversion are high cost, large mass and hydraulic kinetic energy loss. In the traditional torque conversion operation process, three kinds of energy losses mainly exist: pressure losses, friction losses and shock losses reduce the transmission efficiency of the engine and thus fuel economy and traction efficiency.
The differential device is a mechanism capable of achieving rotation of left and right (or front and rear) drive wheels at different rotational speeds. The conventional differential device is composed of left and right side gears, two planetary gears and a gear carrier. The defects of the common differential device can cause idle running and loss of a large amount of power because wheels are suspended; when the situation happens, the differential device continuously and continuously transmits power to idle wheels without grip force, so that the vehicle cannot run forwards, a large amount of power is lost, fuel is wasted, and the performance of the vehicle is damaged. Although most of the prior differential devices are provided with the differential lock to solve the defect, the manual and automatic differential locks can not operate automatically.
Although various defects of a common differential device are successfully overcome in the Torsen differential device in the current market, the Torsen differential device is complex in structure, high in manufacturing cost, large in weight and size and large in influence on the gravity center of a vehicle; and a single wheel cannot be locked by 100 percent, and when the friction force difference in the inclined plane is large, the single wheel is easy to slip, and the traction force is lost.
