Helical tooth limited slip differential with automatic locking function

Abstract

The invention relates to a helical tooth limited slip differential with an automatic locking function, which comprises a shell. A left half axle gear and a right half axle gear are laterally symmetrically arranged in the shell; the left half axle gear and the right half axle gear are respectively meshed with planetary gears; the shell is provided with a locking device. The helical tooth limited slip differential with the automatic locking function, which is disclosed by the invention, makes up the defect that a locking differential is equivalent to a common open differential under the nonlimiting condition and cannot limit sliding of wheels. A helical tooth limited slip functional part of the helical tooth limited slip differential can automatically work, does not need to be artificially interfered and transfers the torque in real time, can well inhibit the wheels from sliding on ice and snow, muddy, sloppy and gravel pavements and ensures that a vehicle safely runs. The differential also has a function of locking the wheels in the limit state that the wheels at one side of the vehicle are suspended in the air and completely lose the adhesive force.

Description

technical field [0001] The invention relates to an automobile part, in particular to a helical tooth limited-slip differential with an automatic locking function. 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, some models of some automobile manufacturers are equipped with imported locking differentials. Although it solves the problem of vehicle driving under the limit situation where the wheels on one side of the vehicle are suspended in the air and completely loses adhesion, it cannot solve the problem in non-limit situations. Under normal circumstances, this kind of differential is equivalent to an ordinary open differential, there will be slippage, the transmission efficiency is not high, and even the problem of tail flicking out of control
