Abstract

The invention discloses a car rear axle differential device comprising a right semi-shaft gear, a conical gear, a lubricant collecting tank and an outer shell. The outer shell is internally provided with an input shaft gear, an input shaft is arranged below the input shaft gear, and the input shaft gear is connected with the conical gear. A lower frame is arranged on the side face of the lower end of the conical gear, a lower electromagnetic clutch is arranged at the upper end of the lower frame, and a lower connecting column is arranged at the upper end of the lower electromagnetic clutch. A lower planetary gear is connected to the end, away from the lower electromagnetic clutch, of the lower connecting column, an upper frame is arranged on the side face of the upper end of the conical gear, and an upper electromagnetic clutch is arranged at the lower end of the upper frame. The lower end of the upper electromagnetic clutch is provided with the lower connecting column, and the lower end of the lower connecting column is connected with an upper planetary gear. The car rear axle differential device has the beneficial effects that components can be lubricated, lubrication can be circularly conducted, autorotation of the planetary gears can be well controlled through arrangement of the electromagnetic clutches, and the anti-skid effect is achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile rear axle differential device. Background technique [0002] The rear axle of a car refers to the bridge behind the car. If it is a vehicle driven by the front axle, then the rear axle is just a follower bridge, which only plays the role of carrying. Generally, there is also a transfer case in front of the rear axle. There is usually a differential on the rear axle. A car differential is a mechanism that enables the left and right drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning or driving on an uneven road, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the speed difference between the left and right wheels...
