Abstract

An embodiment of the present application provides a driving device for rotating an axle of a vehicle. The driving device comprises a motor, a speed reduction device, a shell and a ventilation part; the speed reduction device is connected with the motor; the shell having a motor accommodating part in which the motor is accommodated and a gear accommodating part in which the reduction gear is accommodated, and oil is accommodated in at least one of the motor accommodating part and the gear accommodating part; and the ventilation part is arranged in the housing, the ventilation part is provided with a convex part protruding toward the inside of the housing and a ventilation hole part located inside the convex part and communicates the inside and the outside of the housing; wherein the driving device further comprises a cover part which is fixed on the convex part and covers the opening of a vent hole part; and one of the cover part and the convex part is provided with a claw part which is clamped with the other one of the cover part and the convex part. According to the embodiment of the invention, oil can be prevented from flowing into the ventilation part by arranging the cover part, the convex part and the cover part are fixed in a clamping manner, bolts are not needed for fixation, and the number of parts is reduced.

Description

technical field [0001] The embodiments of the present application relate to the electromechanical field, and in particular, to a driving device. Background technique [0002] At present, the structure of the air vent is installed in the housing of the driving device. However, due to vehicle vibration and other reasons, oil accumulated at the bottom of the housing may enter the vent hole. Therefore, when the pressure in the housing is released, there is a possibility that oil may be ejected. [0003] In order to prevent oil from flowing into the breather, a conventional technique discloses a structure in which a box is provided below a pipe of the breather, and the box is fixed by bolts of a bracket. However, this configuration increases the number of parts and increases man-hours for assembly. [0004] It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the ...
