Description
Technical field
The invention belongs to differential art fields, refer in particular to a kind of automobile differential with anti-skidding latch functions.
Background technique
Under steam, there are two types of states for the relative motion of wheel road pavement for automobile --- roll and sliding, wherein slide and
It is divided into and trackslips and slide two kinds.When automobile turning traveling or in uneven road surface straight trip, because two sides wheel moves within the same time
The curve distance crossed is different, if two side drive wheels only use a stiff shaft driving, the two angular speed is necessarily equal, must there is one
Side vehicle wheel side rolls side sliding, and another-side vehicle wheel side rolls side and trackslips, and sliding of the wheel to ground, is stranded motor turning
Difficulty, power consumption increase, and driving up easily makes certain another parts and tire wear.So should avoid generating it as far as possible, current
Differential mechanism is mostly to pass through a differential gear systems by the driven gear of main reducing gear --- differential mechanism respectively drives automobile
Two sides semiaxis and driving wheel solve the problems, such as this.There are still some shortcomings in structure and performance for existing many type differential mechanisms
Place: some is without latch functions；Differential mechanism with latch functions is in bad road traveling, when left and right or forward and backward driving wheel
When attachment condition between road surface differs larger, when cutting the throat muddy or ice and snow road if any a driving wheel contact, even if
Separately-a wheel is on good road surface, and automobile often cannot still advance this is because most of differential mechanisms are turned round with mean allocation
The characteristics of square, the torque for being assigned to the wheel and can only be drawn with the moment of torsion etc. for passing to very little on the driving wheel to trackslip
The too small reason of power., should be using when a driving wheel spike in order to improve the driving performance of automobile, differential mechanism has locking whole
Torque goes the function of being transmitted to the driving wheel not trackslipped, and makes automobile to generate foot energy tractive force using the adhesive force of this driving wheel
Continue to travel.
