Abstract

The invention discloses an integrated power device of an electric car. The integrated power device comprises a driving motor, a planetary transmission assembly and a shifting assembly. The driving motor comprises a stator, a rotor, an outer rotor shaft and an inner rotor shaft. The planetary transmission assembly is arranged at one end of the driving motor, and comprises an outer sun gear, an inner sun gear, a long planet gear, a short planet gear, a planet carrier and an output flange. The shifting assembly is arranged at the other end of the driving motor, and comprises a fly wheel, a clutchdriven sheet, a press plate, a separation bearing, a braking piston, a braking friction plate and an end cover towards the other end along the driving motor. A planetary transmission and the shiftingassembly are arranged at two sides of the driving motor respectively, and accordingly, transmission oil is prevented from flowing to a brake shoe and a clutch plate of the shifting assembly during seepage; the separation bearing and the braking piston are driven to be attached to the braking friction plate or the clutch driven sheet, so that start and stop as well as the rotation mode of the planetary transmission assembly are controlled, and output speed of the motor is adjusted.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electric vehicle integrated power device. Background technique [0002] At present, the driving devices of my country's new energy pure electric vehicles mainly have structural forms such as direct drive of the motor, motor connected to the reducer, and AMT transmission connected to the rear end of the motor, as the vehicle power drive device. [0003] Due to design concept factors, early pure electric vehicles used motor direct drive, and some system suppliers used motor accelerator and decelerator structure as the vehicle drive power device. The vehicle could not adapt to long ramps, fast acceleration and other operating requirements, and the overall driving performance of the vehicle was poor. . In recent years, with the continuous improvement of the requirements of the country, users, and OEMs in terms of vehicle lightweight, power saving, and economy, various...
