The main function of the gearbox box is to support the drive shafts, ensure the center distance and parallelism between the shafts, and ensure the correct installation of the gearbox components and the engine. The role of the automobile gearbox: 1. According to the road conditions And the needs of changes in driving conditions, change the driving speed of the car to provide appropriate driving force for the car; 2. Cut off or transmit engine power as needed, the engine can effectively output power or idle speed.
Introduction to the structure of the gearbox: 1. Hydraulic torque converter: A non-rigid torque converter that uses liquid as the working medium. It is one of the forms of hydraulic transmission. The hydraulic torque converter has a closed working chamber in which the liquid circulates. The pump wheel, turbine and guide wheel are respectively connected with the input shaft, output shaft and housing. When the power machine (internal combustion engine, electric motor, etc.) drives the input shaft to rotate, the liquid flows out of the centrifugal pump wheel, passes through the turbine, the guide wheel and then returns to the pump wheel, and circulates again and again. The pump wheel transmits the mechanical energy of the input shaft to the liquid. The high-speed liquid drives the turbine to rotate, transferring energy to the output shaft. 2. Planetary gear transmission mechanism: The planetary gear mechanism is composed of sun gear, planetary gear, planetary carrier and ring gear. 3. Hydraulic control system: The hydraulic control system is based on the motor to provide power, and uses a hydraulic pump to convert mechanical energy into pressure to promote hydraulic oil. By controlling various valves to change the flow direction of the hydraulic oil, so as to promote the hydraulic cylinder to make different strokes, different directions of action, complete a variety of equipment different action needs. 4. Oil filter: Oil filter is a filtration device that uses gravity, centrifugation, pressure, vacuum distillation, mass transfer and other technical methods to remove mechanical impurities, oxidation by-products and moisture in impure oil. The oil filter is mainly used to improve the cleanliness of the oil used in machinery and electrical appliances, make it play the best performance and extend the service life of the equipment.
