Abstract

The invention discloses a gearbox for hybrid power. The gearbox for hybrid power comprises an input shaft, an output shaft, a first transmission mechanism connected with a motor and the output shaft, a second transmission mechanism connected with the input shaft and the output shaft, and a third transmission mechanism connected with a generator and the output shaft, wherein the input shaft is connected with a first clutch, the generator is connected with a second clutch, and the first clutch and the second clutch are connected with an engine. The gearbox for hybrid power is simple in structure and clear in gear shifting logic. Under the condition of sufficient electric quantity, dual-motor driving can be realized; common driving of the engine and the motor can be realized; under the condition of insufficient electric quantity, range extending mode driving can be achieved, namely, the engine drives the generator to generate electricity, and the generated electric quantity is input into the motor to drive the vehicle; in the pure engine driving mode, whether the generator is driven to generate electricity or not can be judged according to the electric quantity; and meanwhile, the parking power generation function is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission, in particular, the invention relates to a transmission for hybrid power. Background technique [0002] At present, with the development of society, more and more automobiles have become the main means of transportation for people, but the exhaust emissions of automobiles have also become the cause of environmental pollution. In order to improve the deteriorating automobile emission problem, the state has implemented relevant measures to force automobile manufacturers to develop in the direction of small displacement, light weight and new energy. Hybrid power is currently a transitional new energy solution that is more suitable for China's national conditions. Hybrid vehicles generally require a power coupling mechanism to coordinate the power output of the engine and the motor, and can also select the power output mode to make the engine work in the economic zone, and take into a...
