The invention belongs to the technical field of vehicle transmission and particularly relates to a hybrid power multi-gear transmission. The power gear shifting parallel type hybrid power multi-gear transmission comprises an engine (101), a clutch (103), a motor (102) and a transmission body (104). According to the technical scheme, the power of the engine (101) is input to an engine input shaft (301) through the clutch (103); and the power of the motor (102) is input to a motor input shaft (305). The transmission body (104) is composed of a multi-freedom dead axle gear mechanism, can be coupled with the power of the engine (101) and the power of the motor (102) and can achieve gears of seven matched engines and gears of three matched motors. According to the power gear shifting parallel type hybrid power multi-gear transmission, power gear shifting and hybrid power working conditions can be achieved, the power performance of a vehicle is improved, the gear shifting quality is improved, the abrasion of the clutch is reduced, and fuel economy is improved.
Description
technical field [0001] The invention belongs to the technical field of vehicle transmission, and in particular relates to a hybrid multi-speed gearbox. Background technique [0002] Hybrid technology has the advantages of reducing emissions and fuel consumption, and at the same time improves vehicle dynamic performance, which has become the development direction of future automotive power transmission technology. The advantages of parallel hybrid power are: the power of the engine can be directly used to drive the vehicle without energy conversion, the energy loss is small, and the structure is simple; the motor can be used as a motor or a generator, and a smaller power can be used The motor has simple structure and low cost. In the parallel hybrid technology, the motor mainly realizes the power assist under the rapid acceleration condition or the low-speed engine condition, improves the power performance, and improves the fuel economy of the engine; in the deceleration con...
