Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Such as Figure 1-4 As shown, the present invention provides a technical solution: a cooling and sealing mechanism for the differential case of an electric vehicle, including a main housing 1 and a sub-housing 2, the main housing 1 and the sub-housing 2 are matched and passed through The connecting bolts form the case body of the differential case. The side walls of the main housing 1 and the auxiliary housing 2 are provided with cooling chambers 11 com...

Abstract

The invention relates to the technical field of a box body structure of a differential box of an electric vehicle, and discloses a cooling and sealing mechanism for a differential box of an electric vehicle. The cooling and sealing mechanism comprises a main shell and an auxiliary shell, the main shell and the auxiliary shell are matched and form a differential box body through connecting bolts, cooling cavities which communicate with each other are formed in the side walls of the main shell and the auxiliary shell, connecting plates are connected between the inner side walls of the cooling cavities, and circulating holes are formed in the connecting plates. According to the cooling and sealing mechanism for the differential box of the electric vehicle, cooling liquid can be circularly guided into inner cavities of the cooling cavities, heat exchange is carried out on heat of an inner cavity of the differential box body, the cooling and sealing mechanism is different from a traditional mode of adding cooling fins or cooling oil, the heat exchange efficiency of the cooling liquid is improved, the sealing performance of the connection between the main shell and the auxiliary shell is effectively detected, the cooling liquid circulating in the cooling cavities is prevented from overflowing into the differential box body, normal use of lubricating oil of an internal structure is prevented from being influenced, and the stability of cooperation between the structures is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle differential case box structure, in particular to a cooling and sealing mechanism for electric vehicle differential case. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, the electric vehicle uses the battery as the energy source. Through the controller, the motor and other components, the electric energy is converted into mechanical energy movement to control the current and change the speed of the vehicle. The differential is an important component of the electric vehicle components. play an important role in the driving of the car. [0003] The differential is composed of planetary gears, planetary gear carriers (differential case), half shaft gears and other parts. The power of the motor enters the d...
