Abstract

The invention discloses a coupling (300). The coupling (300) comprises an input part (1) and an output part (2), wherein the coupling (300) further comprises an insulating part (3) which is coaxially and fixedly arranged between the input part (1) and the output part (2). The invention further discloses a connecting structure for a motor and speed reducer or the motor and a transmission of an electric vehicle. The coupling has an insulating function, can prevent the electric conduction between an input shaft and an output shaft, and has higher safety.

Description

technical field

[0001] The invention relates to the field of automobiles, in particular to a shaft coupling and a connection structure between a motor and a reducer or a motor and a transmission for an electric vehicle. Background technique

[0002] With the advancement of science and technology, the use of environmentally friendly and energy-saving electric vehicles is becoming more and more widespread. Electric vehicles have contributed to the protection of the environment and the effective use of non-renewable energy. Usually, an electric vehicle is driven by a motor, and the output shaft of the motor rotates at high speed, and the output shaft is connected with the input shaft of the reducer or transmission through a coupling, and the power of the motor is transmitted to the reducer or transmission, and then transmitted to the On the driving wheel, and then drive the electric vehicle to move.

[0003] Couplings are usually used to connect two shafts (driving shaft and d...
