Waterproof air-cooling heat dissipation structure of electric automobile hub motor

Abstract

The waterproof air-cooling heat dissipation structure of the electric automobile hub motor comprises an automobile body, a control center is fixedly connected in the automobile body, four control rods are symmetrically arranged on the left side and the right side of the control center, the four control rods penetrate through the automobile body and are rotationally connected with the automobile body, and four wheels are symmetrically arranged on the outer side of the automobile body. Cavities are formed in the inner sides of the four wheels, hub motors are fixedly connected in the cavities, through holes are formed in the side walls of the cavities, bearings are fixedly connected in the through holes, the control rods penetrate through the bearings and are fixedly connected with the hub motors, and cold steel pipes are fixedly connected to the upper sides in the bearings. The cold steel pipe penetrates through the bearing and the vehicle body, and the cold steel pipe is located in the vehicle body and fixedly connected with a cold hose. According to the invention, the heat dissipation operation of the hub motor can be well completed, the overall sealing effect is good, the operation is simple, and the practicability is high.

Description

technical field [0001] The invention relates to the field of underwater crawler electric drive machinery, in particular to a waterproof air-cooled heat dissipation structure for an electric vehicle wheel hub motor. Background technique [0002] At present, the corresponding electric special vehicles are often used, and the electric vehicles move by driving the crawler to complete the cleaning and dredging operation of the water delivery channel, and the electric vehicle underwater operation directly carries out the corresponding cleaning operation. At present, in order to better complete the cleaning operation, in-wheel motors are often used instead of traditional electric motors. Electric vehicles using in-wheel motors have high work efficiency, flexible operation, and can simplify the chassis. However, in the actual use process, although the underwater environment The temperature is low, but the long-term operation of the in-wheel motor will cause the temperature to rise, ...

AI Technical Summary

Problems solved by technology

At present, in order to better complete the cleaning operation, in-wheel motors are often used instead of traditional motors. Electric vehicles using in-wheel motors have high work efficiency, flexible handling, and can simplify the chassis. However, in actual use, although the underwater environment The temperature is low, but the long-term operation of the hub motor will cause the temperature to rise, which will affect the normal working state of the electric vehicle as a whole. Therefore, a waterproof and air-cooled heat dissipation structure for the hub motor of the electric vehicle is provided
