Problems solved by technology

[0003] In new energy vehicles, the wheel motor replaces the traditional engine. The wheel motor is essentially a DC drive motor. It needs to be cooled by a cooling system during long-term driving. The existing solution is mainly water cooling, but the water cooling device It is directly installed on the outside of the wheel motor for wrapping. On the one hand, it takes up a lot of space. On the other hand, if it does not work continuously, it will affect the normal cooling of the wheel motor and cause a great waste of resources. Therefore, we propose an electric vehicle wheel motor Drive axle

Abstract

The invention discloses an electric automobile wheel side motor drive axle which comprises two supporting plates, the two supporting plates are arranged at the two ends of a drive axle body, ventilation openings are formed in the supporting plates, a ventilation pipe is arranged between the two supporting plates, the two ends of the ventilation pipe are connected with two ventilation openings correspondingly, each supporting plate is provided with a covering mechanism and a working mechanism, and the working mechanism is arranged on one side of the supporting plate. A supporting frame is arranged on the outer side of the ventilation pipe, a power mechanism is arranged on one side of the supporting frame, and under the normal condition, a covering assembly is folded, so that the outer side of the wheel side motor has a rich space, heat is reduced, and in the long-time running process of the new energy automobile, the covering assembly covers the outer side of the wheel side motor while an air inlet assembly is opened, air at the bottom of the automobile is guided into the covering assembly to cool and protect the wheel side motor, additional cooling equipment is not needed, and energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electric vehicle wheel motor drive axle. Background technique [0002] With the gradual withering of oil resources and the gradual increase of air pollution, the society is increasingly calling for new energy vehicles, including pure electric, hybrid, plug-in, fuel cell and other forms of vehicles. New energy vehicles greatly reduce the impact on Oil dependence and air pollution. Compared with traditional internal combustion engine vehicles, new energy vehicles have undergone tremendous changes in both the general layout of the vehicle and the drive system assembly due to the different forms of energy supply. The drive system assembly is crucial to the vehicle. Important, it not only undertakes the carrying function and driving function, but also directly determines the safety and comfort performance of the vehicle. [0003] In new energy vehicles, the wheel moto...
