Electronically controlled locking screw tooth limited slip differential

Abstract

The invention relates to an electronically controlled locking screw tooth limited slip differential comprising a housing in which a left side gear and a right side gear are symmetrically arranged in the housing. A connecting plate is arranged on the outer side of the right end of the housing. An extension end of a right semi-axis gear with an outer spline shaft is arranged in a cavity formed by the connecting plate and the right end cover; the left end face of the right end cover is provided with a groove. A locking connecting ring is arranged at the bottom of the groove. A locking pin is arranged in a guide hole. A guide sleeve is sequentially sleeved with a friction plate, a cam, an electromagnet, an electromagnet retainer and a clamp spring. The electronically controlled locking screw tooth limited slip differential has functions of normal running and slip limiting of non-extreme relieving, and the function of completely locking semi-axes on two sides in the extreme state, and can inhibit slipping of wheels in the case of icy, muddy, wet, and gravel roads.

Description

technical field [0001] The invention relates to an automobile part, in particular to an electronically controlled locking helical tooth limited-slip differential. Background technique [0002] When the vehicle is running, the rolling strokes of the left and right wheels are often different at the same time, that is, there is a speed difference between the wheels on both sides, especially when the vehicle is turning, the difference in the speed of the wheels on both sides is more obvious. The differential is applied to various vehicles. The purpose is to allow the speed of the wheels on both sides to be inconsistent. [0003] The common open differential that is commonly used now is mainly composed of a housing, a planetary gear shaft, a planetary gear, and a side gear. The side gear is connected to the driving wheel through a half shaft. It can meet the driving requirements of the vehicle, but when the vehicle is driving on bad roads, especially on ice, snow, muddy, slipper...

AI Technical Summary

Problems solved by technology

[0003] The common open differential that is commonly used now is mainly composed of a housing, a planetary gear shaft, a planetary gear, and a side gear. The side gear is connected to the driving wheel through a half shaft. It can meet the driving requirements of the vehicle, but when the vehicle is driving on bad roads, especially on ice, snow, muddy, slippery, gravel, and rough and rough roads, the adhesion of the wheels on both sides will be very different. The small side will slip and spin, causing the vehicle to fail to drive, or even to drift out of control

At present, in some models of some automobile manufacturers, the existing locking differential can solve the problem of vehicle driving under the limit situation where the wheel on one side of the vehicle is suspended in the air and completely loses adhesion, but it cannot solve the problem in the non-limit situation. This kind of differential is equivalent to an ordinary open differential, and there will be slippage, low transmission efficiency, and even the problem of tail flicking out of control.
