Motor cooling water pipe joint and driving motor

Abstract

The invention discloses a motor cooling water pipe joint and a driving motor. The motor cooling water pipe joint comprises a machine shell water pipe joint, a hoop, a water pipe, a sealing ring, a joint outer ring and a check buckle; and the sealing ring is arranged on the inner side of the machine shell water pipe joint, the joint outer ring is connected with one end of the inner side of the machine shell water pipe joint, the inner side of the joint outer ring is sleeved with the check buckle, and the inner side of the check buckle is provided with the water pipe. According to the motor cooling water pipe joint and the driving motor, the sealing property and the fastening property of the motor cooling water pipe can be ensured through the sealing ring in the water pipe joint and the check buckle arranged on the water pipe in a sleeving manner; and compared with a traditional hoop for fixing, the joint is less prone to loosening, the problem that in the long-term use process of the water cooling motor, the sealing property of the water pipe is damaged due to the fact that the cooling water pipe joint partially falls off can be solved, and the service life of the joint is effectively prolonged, so that the motor is better protected.

Description

technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a motor cooling water pipe joint and a driving motor. Background technique [0002] Due to the high power density and small size, the driving motor of new energy vehicles often generates a lot of heat. At present, the motors of new energy vehicles generally use cooling water to cool down, and the cooling water is passed into the casing from the water channel interface at the end of the casing through an external water pump. The internal circulating water channel cools the motor body. [0003] The driving motors used in new energy vehicles are basically installed at the bottom of the vehicle body, and generally there is no protective cover structure. The vehicle and the motor will generate high-frequency vibrations and vibrations of the vehicle body during operation. In the prior art, the connection method of the motor cooling water pipe To: Use a rubber hose to fit ...

AI Technical Summary

Problems solved by technology

This kind of fastening method is easy to corrode and loosen after the long-term operation of the vehicle, resulting in the easy loosening of the water pipe joint. In the case of operation and use, it is necessary to ensure that the position of the water pipe joint has good sealing and tightness
