The front end of the motor housing is provided with a front cover, and the front cover is provided with a shaft hole, and a first bearing is provided in the shaft hole, and the rotating shaft extends forward through the first bearing, and a first bearing is provided in the front cover. Two annular cooling chambers, the second annular cooling chamber communicates with the first annular cooling chamber, a ring-shaped back shell is provided at the rear end of the motor housing, and a third ring is arranged in the ring-shaped rear shell A plurality of connecting rods are connected between the annular rear shell and the front cover, and the second annular cooling chamber and the third annular cooling chamber communicate with each other through the connecting rods.

Description

technical field [0001] The invention relates to an electric drive system of a new energy vehicle with auxiliary heat dissipation. Background technique [0002] With the development of science and technology, the popularity of new energy applications has also been greatly improved. New energy vehicles are undoubtedly the most concerned products in new energy projects, and the most important components of the existing new energy vehicle electric drive system , the motor is the core component. [0003] However, during the long-term use of the existing traditional motor, the rotation of the motor rotor will generate a large amount of heat, and the existing motor shell often does not have the function of self-dissipating heat, and the large accumulation of heat will cause a large amount of damage to the performance of the motor. The motor is prone to failure, which will have a great impact on the internal structure and performance of the motor itself and the service life of the ...
