Abstract

The invention belongs to the technical field of automobiles and particularly relates to gearboxes. A multi-gear power gear shifting parallel hybrid power gearbox comprises an engine, a motor and a gearbox body. Power of the engine passes a clutch and then is input to an input shaft of the engine; power of the motor is input to an input shaft of the motor; the gearbox body is composed of a multi-freedom-degree fixed shaft gear mechanism, and the power of the engine and the power of the motor can be coupled. The multi-freedom-degree fixed shaft gear mechanism is composed of six pairs of gear mechanisms and four synchronizers and is simple in structural arrangement; and through reuse of the gear pairs, eight gears matched with the engine and four gears matched with the motor can be provided, the power performance and gear shifting comfort are improved, and the parallel hybrid power technology is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a gearbox. Background technique [0002] Hybrid technology has the advantages of reducing emissions and fuel consumption, while improving vehicle dynamic performance, and has become the development direction of automobiles. The advantages of parallel hybrid power: the power of the engine can be directly used to drive the vehicle, there is no 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 motor with a smaller power can be used , 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 condition, the braking energy recovery is realized; , can realize pure electric drive. Comp...
