Description
Technical Field
The utility model relates to a wheel hub motor technical field, concretely relates to lightweight two-wheeled storage battery car wheel hub motor housing.
Background
With the phenomena of global environmental pollution aggravation, resource shortage and the like, energy conservation and emission reduction become a trend that society cannot block. The motor driving system is a core system of the vehicle, replaces the function of a traditional vehicle engine, and has higher transmission efficiency.
The hub motor is the heart of an electric drive system, and for the existing two-wheeled battery car, due to the sealing property of the hub motor, heat generated by the motor cannot be well dissipated, so that the running efficiency of the motor is seriously influenced; the shell of the hub motor in the current market is made of aluminum, and although the aluminum shell can meet the strength requirement of the shell, the aluminum shell is heavy; if a plastic piece is selected to manufacture the hub motor shell, the heat dissipation performance is poorer than that of an aluminum shell; based on the above problems, it is very necessary to design a hub motor housing with light weight and good heat dissipation performance.
SUMMERY OF THE UTILITY MODEL
A primary object of the utility model is to provide a lightweight two-wheeled storage battery car wheel hub motor housing for solve above-mentioned technical problem.
In order to achieve the above object, the utility model provides a following technical scheme: a light-weight two-wheel storage battery car hub motor shell comprises a motor shell, wherein a rotating shaft is installed in the middle of the motor shell, a plurality of air holes are formed in the inner side surface of the motor shell in a circumferential array arrangement mode, and a breathable film is arranged on each air hole; the motor housing is made of heat resistant plastic.
On the basis of the above scheme and as a preferable scheme of the scheme: the number of the air holes and the number of the air permeable films are both 4.
On the basis of the above scheme and as a preferable scheme of the scheme: the breathable film is connected with the motor shell into a whole in an ultrasonic welding mode.
On the basis of the above scheme and as a preferable scheme of the scheme: the breathable film is a PTFE film.
On the basis of the above scheme and as a preferable scheme of the scheme: the heat-resistant plastic is a PA66-GF50 material.
The utility model has the advantages as follows: the motor shell of the hub motor is optimized on the existing motor shell and is made of PA66-GF50 material, the material can also keep stronger strength and rigidity at higher temperature, and is lighter than the existing aluminum piece, so that the motor shell can be lightened; in addition, 4 air holes are formed in the inner surface of the motor shell, and PTFE air-permeable films are arranged on the air holes, so that air exchange can be carried out between the inside and the outside of the motor shell, and the purpose of heat dissipation is achieved.
