Problems solved by technology

[0004] In view of the deficiencies in the prior art, the present invention provides an air-cooled heat dissipation mechanism for the hub motor of electric vehicles, which can quickly disperse the heat generated during the operation of the hub motor, and overcome the problems caused by the increased power and torque of the hub motor. Overload work causes its temperature to be too high and cannot operate normally, ensuring the safety of electric vehicles during driving

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0019] Such as figure 1 ,Such as figure 2 As shown, the present invention provides an air-cooled and heat-dissipating mechanism for a hub motor of an electric vehicle, comprising a hub motor housing 1 and a motor winding 2. Outer raised blades3. Considering that the work of the automobile hub motor is mainly carried out through the motor winding, the motor winding will generate a lot of heat. If the blades are set relative to the motor winding, the best heat dissipation effect can be achieved. The blades 3 are arc-shaped. The angle of the air outlet of the blade is less than 90 degrees. The distance between each blade 3 is 20mm-80mm. The thickness and quantity of the blades 3 should be calculated and determined according to the heat dissipation of the hub motor. The thickness of the blades selected by the present invention is in the range of 3 mm to 5 mm. The ...

Abstract

The invention discloses an air cooling heat dissipation mechanism for a wheel hub motor of an electromobile. The air cooling heat dissipation mechanism comprises a wheel hub motor outer shell and a motor winding, and at least two vanes which protrude outwards are distributed on the circumference of the outer surface of one side of the wheel hub motor outer shell in an equidistant mode. Heat generated in the operation process of the wheel hub motor can be quickly scattered by the mechanism, the defects that operation can not be normally conducted due to too high temperatures caused by overload work such as increasing of the power of the wheel hub motor and increasing of torque are overcome, and the safety in the traveling process of the electromobile is guaranteed.

Description

technical field [0001] The invention relates to a heat dissipation mechanism for electric vehicle equipment, in particular to an air-cooled heat dissipation mechanism for a hub motor of an electric vehicle. Background technique [0002] An electric vehicle hub motor is a hub unit that integrates an electric motor, a transmission system, and a braking system. In recent years, with the rise of electric vehicles, in-wheel motors have attracted more and more attention. Compared with the centralized drive, the use of in-wheel motors in electric vehicles has the following advantages: (1) The power control is changed from hard connection to soft connection, and through the electronic wire control technology, the stepless speed change of each electric wheel from zero to maximum speed and The differential speed requirement between the electric wheels omits the transmission system required for centralized driving of electric vehicles, making the drive system and the vehicle simple in...
