Abstract

The invention provides a planetary carrier. The planetary carrier comprises a main planetary carrier and a planetary carrier end cover which are formed in a split manner, wherein the planetary carrierend cover comprises an end cover main body and a tooth part located at the periphery of the end cover main body; and the planetary carrier end cover is relatively rotationally connected with the mainplanetary carrier in a manner of interference fit, spline connection and / or welding. The planetary carrier has a parking locking function, and is compact in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a planetary reduction and differential system of a vehicle, in particular to a planetary reduction and differential system integrated with a planetary gear set and a lightweight differential, and more particularly to a planet carrier integrated with parking teeth. Background technique [0002] refer to figure 1 , a known planetary reduction and differential system in the prior art integrates a planetary gear set and a lightweight differential. Wherein, the planetary carrier of the planetary gear set includes a main planetary carrier 1 and a planetary carrier end cover 2 , and the planetary carrier end cover 2 is usually fixed to one end of the main planetary carrier 1 by screws. [0003] The above-mentioned planetary reduction and differential system does not have a parking lock function, and when it is necessary to add a parking lock function to the vehicle, it is necessary to install related components in an additional space...
