Abstract

The invention discloses a start power generation system with a two-stage forward and backward differential transmission device, belonging to the field of automotive electrical appliances, comprising astarting generator and a double-stage forward and backward differential transmission device composed of a first planetary gear mechanism, a second planetary gear mechanism, a bracket and a pluralityof friction plates. Two-stage forward and backward differential transmission device realize different gear transmission of planetary gear mechanism through engagement and separation between differentfriction plates. In the vehicle starting stage, the engine starting speed is low, adding a two-stage forward and backward differential transmission can make the starting generator start the engine smoothly and efficiently. In the power generation stage, the speed of engine ring gear is higher, and there is an increasing speed transmission ratio between ring gear and output shaft, which will make the speed of output shaft abnormally high. The start power generator can still work normally when the speed of engine ring gear is higher after adding two-stage forward and backward differential transmission device to adjust speed.

Description

technical field [0001] The invention relates to an automobile starter-generator, in particular to a starter-generator system with a dual-stage forward and reverse differential transmission device, belonging to the technical field of automobile electrical appliances. Background technique [0002] In the past, a starter and a generator were installed on the car, and the two work independently of each other. After the start process is completed, the starter is in an idle state, which will inevitably lead to the starter not working most of the time but occupying the limited space of the car. The weight of the car is increased, so the starter-generator integration technology is needed to overcome this shortcoming. [0003] In the starting stage of the vehicle, the starting speed of the engine is low, but a large starting torque is required; in the running stage of the vehicle, the speed of the engine ring gear is higher, and the speed of the output shaft connected with the ring g...
