Automatic limited slip differential of planetary gear train

Abstract

The invention provides a planetary gear train automatic limited slip differential which is composed of a main differential, a planetary gear train differential controller, a left driving half shaft, a right driving half shaft and a clutch, and the planetary gear train differential controller is composed of a first planetary gear train differential controller unit and a second planetary gear train differential controller unit. The first planetary gear train differential controller unit is composed of a first planetary gear train and a first overrun clutch connected with the first planetary gear train, the second planetary gear train differential controller unit is composed of a second planetary gear train and a second overrun clutch connected with the second planetary gear train, and the planetary gear train differential controller automatically limits the maximum rotating speed difference of left and right wheels. By means of the structure, a vehicle can run on a smooth road surface without slip loss, power of an engine can still be automatically transmitted to wheels with adhesive force on muddy and icy and snowy road surfaces and even under the condition that the vehicle idles on one side and has no adhesive force, slipping of the wheels is prevented, and normal running and passing of the vehicle are guaranteed.

Description

technical field [0001] The present invention is a purely mechanical planetary gear train automatic limited-slip differential, which enables the vehicle not only to have the ability to run at normal differential speeds on good roads, but also to be able to operate on extremely harsh all-weather roads such as all-terrain, muddy, slippery, and ice-snow roads. Under working conditions, the machine can automatically control the limited slip, the drive torque can reach the maximum value all the time and the ability of normal differential speed driving. It is suitable for all vehicles that require differential transmission. Background technique [0002] Ordinary car symmetrical conical planetary gear differential is composed of planetary gear, planetary carrier, differential case, half shaft gear and other parts; the power of the engine is input into the differential through the transmission shaft, directly drives the planetary carrier, and then driven by the planetary gear The lef...

Problems solved by technology

[0003] Although the self-locking differentials that have appeared so far have good automatic anti-skid ability, whether it is mechanical or electronic differential anti-skid technology, they generally adopt a high friction torque control method, which has a frictional heating effect and torque control force. Limited, for all-terrain work, poor adaptability to all-weather use environments, let alone high-torque vehicles, most of them are limited to small vehicles

Secondly, for electronically controlled anti-skid differential systems, there are disadvantages of poor adaptability and reliability in relatively harsh environments such as high cold, high heat, high salt humidity, and electromagnetic interference, as well as high costs.
