Abstract

The invention relates to a motor-AMT (automated mechanical transmission) coupling mechanism. An AMT speed reducer portion is characterized in that a first driving gear and a second driving gear are connected onto an input shaft through splines to jointly form an input shaft assembly, a parking gear, a synchronizer mechanism, a first driven gear, a second driven gear, an output shaft and a main reduction driving gear form an output shaft assembly, and a main reduction driven gear and a differential shell form a main reduction assembly. A motor portion comprises a motor shaft and a motor body on the outer side of the motor shaft. Occupied space of a front cabin is greatly reduced after a motor is coupled with an AMT. A gear selecting and shifting controller automatically selects two corresponding transmission ratios of a first gear or a second gear according to actual road conditions, so that the motor continues running with better use efficiency, endurance mileage is increased, the space of the front cabin occupied by a power assembly is saved, and the motor-AMT coupling mechanism is provided with a parking gear so that an electric vehicle runs on a ramp more safely and reliably.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a motor-AMT coupling mechanism. Background technique [0002] Electric vehicles basically use motors and transmissions to replace traditional engines and transmissions. The overall design requirements of electric vehicles are small size, simple structure and light weight, so the transmissions of existing electric vehicles are generally one-stage reducer and two-speed reducer in the majority. In use, the speed of driving is generally realized by controlling the speed of the motor. This reduces the efficiency of the motor and reduces the range of the electric vehicle. However, if a traditional engine motor transmission is used, the space in the front compartment will be increased, the weight of the electric vehicle will be increased, and the cost will be increased. Contents of the invention [0003] The purpose of the present invention is to propose a motor-AMT coup...
