Abstract

The invention provides a new energy automobile motor end cover connecting structure applied to the technical field of new energy automobile motors. The new energy automobile motor end cover connecting structure is characterized in thatthe motor shell (1) of the new energy automobile motor end cover connecting structure is connected with a motor end cover (2) through a connecting bolt, a sealing gasket (3) is arranged at the joint of the motor shell (1) and the motor end cover (2), a cooling water channel (6) is formed between the shell outer layer (4) and the shell inner layer (5) of the motor shell (1), and the lower end of the flange inner wall (8) of a flange (7) is provided with an inclined plane part I (9) which is arranged along the flange inner wall (8). The new energy automobile motor end cover connecting structure is simple in structure, and can effectively guarantee that the motor end cover and the motor shell are effectively attached after being assembled, ensure the sealing performance of the cooling water channel, suppress radial vibration in high-speed operation of the motor, avoid water leakage, improve the NVH performance of the motor, and achieve light weight.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicle motors, and more specifically relates to a connection structure of a new energy vehicle motor end cover. Background technique [0002] With the improvement of consumers' requirements for automobile comfort, the NVH performance of the whole vehicle has been paid more and more attention by people. In the field of new energy vehicles, the NVH of the motor directly affects the performance of the vehicle. There are many ways to use sound-proof materials to wrap motors to reduce vibration noise in the market, and improving the NVH performance of products through structural design is the most effective means. In terms of structural design, major manufacturers generally adopt closed waterways, which can effectively avoid motor vibration, but the manufacturing methods are mostly low-pressure casting and friction welding, which have high production costs and low cooling effects. Due to the good...
