Abstract
The utility model discloses an integral housing of a differential mechanism. The housing comprises a differential mechanism housing and a differential mechanism gear assembly. The differential mechanism housing is of an integral structure, and a good coaxiality is determined in the machining process. Thus, the coaxiality of the housing is easily ensured in the installation process, and the housing can be directly assembled, so that assembling efficiency is improved. Due to the integral structure of the housing, the problem concerning coaxiality for long-term usage is prevented, and a kinematic pair is prevented from having eccentric wear. Service lifetime of the differential mechanism and a whole reducer is extended, and usage cost is reduced. Since eccentric wear does not exist, energy usage consumption is greatly reduced and driving mileage of a fully charged electric car is extended.
