Problems solved by technology

If there is leakage or high-voltage electrostatic discharge in the motor, the output shaft of the motor will be charged, and the current will be transmitted to the input shaft of the reducer or transmission through the coupling, which will make the whole vehicle electrified, which will easily cause electric shock accidents and cause harm to the human body. raise security concerns
[0005] Therefore, in order to prevent the leakage of the motor or the high-voltage electrostatic discharge from being transmitted to the vehicle and cause safety hazards, a coupling with an insulating function is needed to prevent the electrical conduction between the output shaft of the motor and the input shaft of the reducer or transmission.

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...
