Abstract

The invention provides a multi-gear transmission, a four-gear speed change system and a vehicle. The four-gear speed change system comprises an input shaft, a first transmission module, a second transmission module and the multi-gear transmission; a motor drives an input shaft to rotate through the first transmission module; the input shaft drives a first driving shaft and a second driving shaft of the multi-gear transmission to rotate through the second transmission module; and the input shaft is parallel to the first driving shaft and the second driving shaft. Under the condition of hybrid power, the vehicle is started, and the motor provides power; and when the vehicle reaches a certain speed, a third clutch slides to combine the input shaft with an engine, and in particular, a wet clutch is selected to prolong the service life. When the vehicle is parked, the third clutch slides to disconnect the input shaft from the engine, and the engine stops working to achieve an oil saving effect. In a braking state, as the motor is used for braking, the mechanical energy of the vehicle can be converted to electric energy to store in the motor so as to realize the energy recovery.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a multi-speed transmission, a four-speed transmission system and a vehicle. Background technique [0002] Automatic transmission (English: Automatic Transmission, referred to as: AT), also known as automatic transmission, generally speaking, is a kind of automobile transmission that can automatically change the gear transmission ratio during driving, so that the driver does not have to manually change gears, and also For large equipment railway locomotives. [0003] The reason why the automatic transmission can realize automatic shifting is because the position of the driver stepping on the accelerator or the vacuum degree of the engine intake manifold and the driving speed of the car can command the automatic shifting system to work. The control valves in the automatic shifting system Different working states will control the separation and closing of the clutch and the braking and...
