Problems solved by technology

[0002] Usually, the driving motor of the vehicle is installed on the chassis of the vehicle, the space is limited, and the operation of the driving motor will generate a lot of heat, which will affect the performance of the motor and the whole vehicle if it is not dissipated in time. In addition, without a good cooling system, the driving motor cannot be guaranteed. The protection level of the motor shell reduces the reliability of the vehicle and increases the economic cost

Embodiment Construction

[0009] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0010] like figure 1 As shown, the vehicle drive motor cooling device of the present invention includes a drive motor, the drive motor includes a stator and a rotor, and the drive motor is a water-cooled motor; a water conduit is arranged between the stator and rotor of the drive motor, and the space formed by the stator and rotor The upper and lower ends of the cavity are respectively covered with end covers, and the upper end cover 1 and the lower end cover 2 are respectively provided with water inlet and return holes. The water in the pipe is circulated and cooled; the pipes are connected by flanges and placed at the pipe ends.

[0011] When the whole vehicle is running, the heat dissipated by the driving motor and the cooling water are directly exchanged. Outside the driving motor, the circulating water enters the cavity through the water circulation ...

Abstract

The invention discloses a vehicle driving motor cooling device which comprises a driving motor, wherein the driving motor comprises a stator and a rotor, and the driving motor is a water-cooled motor; a water guide tube is arranged between the stator and the rotor of the driving motor, the top and the bottom of a cavity formed by the stator and the rotor are respectively covered by an end cover, the upper end cover (1) and the lower end cover (2) are provided with a water inlet hole and a water return hole respectively, and a water circulation guide tube (4) connected with the water inlet hole and the water return hole is matched with a water pump (3) and a cooler (5) to carry out circulating cooling on water in the cavity. According to the vehicle driving motor cooling device, the structure is simple, the size is small, vehicle chassis space is greatly saved, heat dissipation effects of a heat dissipation device are good, overhigh heat dissipation power is not needed, and additional oil consumption of a finished vehicle is reduced; meanwhile, sealing performance of the water-cooled circulation device is good, the protection grade of a motor outer shell of the motor can be made high on this basis, and reliability of the finished vehicle is improved.

Description

technical field [0001] The invention relates to a vehicle drive motor, in particular to a vehicle drive motor cooling device. Background technique [0002] Usually, the driving motor of the vehicle is installed on the chassis of the vehicle, the space is limited, and the operation of the driving motor will generate a lot of heat, which will affect the performance of the motor and the whole vehicle if it is not dissipated in time. In addition, without a good cooling system, the driving motor cannot be guaranteed. The protection level of the motor shell is lower, which reduces the reliability of the vehicle and increases the economic cost. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle drive motor cooling device, which can effectively dissipate heat from the drive motor, and can also ensure that the drive motor has a higher protection level of the motor shell, improve the reliability of the vehicle, and reduce economic costs; ...
