Abstract

The embodiments of the invention disclose a hybrid power mechanism and an automobile. The hybrid power mechanism includes an engine, motors, a first planetary gear set, a second planetary gear set, a plurality of joint elements and output assemblies; the motors, the first planetary gear set, the second planetary gear set and an input shaft are disposed on a same axis, and P2 clutches are further coaxially disposed between the engine and the motors; the active ends of the P2 clutches are connected to the input shaft, and the passive ends of the P2 clutches are separately connected with motor rotors and first planetary sun gears; and first planetary ring gears are fixed to transmission shells, and the engine, the motors, the first planetary gear set and the second planetary gear set transmit rotation of the engine and the motors to the output assemblies through multi-speed shift through the multiple joint elements. The hybrid power mechanism has the advantages that a plurality of driving modes can be realized, the structure is compact, the price is low, and the energy saving effect is remarkable.

Description

technical field [0001] The invention belongs to the field of automobile transmission systems, and in particular relates to a hybrid power mechanism and an automobile. Background technique [0002] With its superior performance, automobiles have improved people's happiness index in daily life and work. However, its excessive fuel consumption and environmental pollution pose great challenges to oil resources and the ecological environment. Therefore, the automobile industry has to transform from the traditional energy consumption mode to the energy saving and environmental protection mode. In recent years, new energy vehicles represented by pure electric vehicles, hybrid vehicles, and fuel cell vehicles have made significant progress. However, due to the problems of low energy density, short life, high price and pollution of the battery itself, which is one of the key components of pure electric vehicles and fuel cell vehicles, the development progress and industrialization ...
