Description
Technical field
The present invention relates to the actuating unit in the various types of vehicles, be specifically related to a kind of differential mechanism.
Background technique
When turn inside diameter travelled, the curve distance that the wheel of inside and outside both sides rolls across at one time was unequal, and the distance that outboard wheels rolls across is greater than inboard wheel.If the both sides vehicle stationary is on same stiff shaft, the angular velocity of two-wheeled equates that then this moment, foreign steamer must be limit rolling slippage, and interior wheel must be to trackslip in rolling limit, limit.
Equally, during straight-line travelling, the wheel actual curve distance that rolls across in both sides is also unequal on uneven road surface for vehicle, and the single wheel that moves on the significant road surface of waveform is limit rolling slippage, and the opposite side wheel then is to trackslip in rolling limit, limit.Even road is very straight, but because the difference of size error, the degree of wear, inflation pressure and bearing load that tire is made, the rolling radius of each wheel also can not be equal fully.Therefore, as long as it is unequal respectively to take turns angular velocity, the slip of wheel road pavement just certainly exists.Its harm is not only can quicken Tyte Wear, increases fuel consumption, and can cause the deterioration of steering behaviour.
For overcoming above-mentioned deficiency, various types of vehicles all is equipped with differential mechanism between the left and right driving wheel.Because the planetary gear type differential mechanism has advantages such as simple in structure, reliable operation, therefore, it has obtained using the most widely on various types of vehicles.But the shortcoming of this differential mechanism maximum is, since it fifty-fifty distribution of torque take turns to left and right driving, so when a side drive wheel of vehicle touches mire or ice and snow road, even another driving wheel is on good road surface, often vehicle still can not advance, trackslip in wheel original place on muddy road surface, the wheel meeting transfixion on good road surface, and promptly this kind differential mechanism can seriously influence the passing ability of vehicle on bad road surface.Just because of this, people try hard to solve the anti-skidding problem of geaster compensating gear always.
