Description
Technical field
The present invention relates to automobile differential, particularly relate to a kind of differential mechanism anti-slip structure.
Background technique
Differential mechanism is that one can make rotary motion reach two axles from an axle, and makes the differential attachment that the latter can rotate with different rotating speeds each other.Chinese Patent Application No. 2011800533570, publication date be August 21 in 2013 day, be called the automobile differential namely disclosing an existing structure in the patent document of " locking differential electrically triggered ", automobile differential comprises planetary wheel carrier and is positioned at two driving gears of planetary wheel carrier.During use, the left and right semiaxis (when for being then antero posterior axis during center differential) of automobile stretches into through semiaxis mounting hole after in planetary wheel carrier and links together with two driving gears correspondingly, is driven and rotate by driving gear.In using process, need to inject lubricant oil to lubricate differential mechanism with life-saving.
Existing difference device has the following disadvantages: when automobile travels on bad road, can have a strong impact on passing capacity.Such as when a driving wheel of automobile is absorbed in muddy road surface, although another driving wheel is in good road surface, automobile often can not advance (being commonly called as skidding).Trackslip in driving wheel original place now on muddy road surface, the but transfixion of the wheel in good road surface.This is because wheel on muddy road surface and the adhesion between road surface less, the moment of reaction less to semiaxis effect can only be taken turns by this in road surface, therefore to distribute to this torque taken turns also less for differential mechanism, although the adhesion between another driving wheel and good road surface is larger, but because of the feature of mean allocation torque, make this driving wheel also can only assign to the torque with slipping drive wheel equivalent, so that driving force is not enough to overcome running resistance, automobile can not advance, and power then consumes on slipping drive wheel.Now open the throttle and automobile not only can not be made to advance, waste fuel oil on the contrary, accelerate component wear, especially make tire wear aggravate.
Summary of the invention
The differential that the invention provides a kind of two semiaxis when difference device can make the differential mechanism anti-slip structure of two semiaxis synchronous axial system when being greater than setting value, solve existing differential mechanism can have a strong impact on passing capacity problem when automobile travels on bad road.
