The working principle of differential mechanism of the present invention is:
When the power of internal-combustion engine is inputted by the active spur bevel gear (10) of main reducing gear, when in the driven wheel of differential of main reducing gear and external tooth, heterogeneous cam ring (1) is driven and is rotated with constant angular velocity, thrust is produced to rolling into block (5) due to the radius vector change of the heterogeneous cam ring profile of cam ring (1) heterogeneous in external tooth, force roll into block (5) move in the radial guide groove of left half axle frame (2) and promote left half axle frame (2) rotate, meanwhile to contact with the higher pair of right axle shaft central gear (6) and also will promote right axle shaft central gear (6) by rolling into block (5) and rotate, thus form a two degrees of freedom differential system, left half axle frame (2) then passes to power the left side be connected mutually with it with the motion of right axle shaft central gear (6) respectively, right wheel.Right axle shaft central gear (6) and left half axle frame (2) rotate respectively under the effect of driving force, but respective motion state is uncertain, are determined by the different road surface of left and right wheel, bend situation.When automobile straight-line travelling on straight road, when wheel on wheel on left half axle frame (2) and right axle shaft central gear (6) is without speed discrepancy, left half axle frame (2) is identical with the rotating speed of right axle shaft central gear (6), and namely differential mechanism does not have differential action.Now, in differential mechanism, each parts keep geo-stationary, and torque is inputted by cam ring (1) heterogeneous in external tooth, on average passes to left half axle frame (2) and right axle shaft central gear (6) through rolling into block (5).Travel when automobile turning or on rough road, when there is speed discrepancy in left and right two-wheeled below, roll into block (5) ordering about by heterogeneous in external tooth cam ring (1), left half axle frame (2) and right axle shaft central gear (6) is driven to rotate on the one hand, radially moving in the radial guide groove of left half axle frame (2) while rotating with left half axle frame (2) on the other hand, ensureing that left half axle frame (2) and right axle shaft central gear (6) are able to realize differential when not departing from transmission.And owing to rolling into the effect of block (5) to the moment that the active force of left half axle frame (2) and right axle shaft central gear (6) produces, the driving wheel making rotating speed slow can obtain the torque that the fast driving wheel of specific speed is larger.
For the differential property of differential mechanism of the present invention is described, if left and right wheel speed is respectively n after automobile
2, n

As established automobile to turn left, two front-wheels of automobile are under the effect of steering equipment (Figure 10), and the axis of its axis and automobile two trailing wheel intersects at P point, now can be considered that whole automobile turns round around P point.When wheel and ground non-slip, the rotating speed of two trailing wheels should be directly proportional to turning radius, can be obtained by Figure 10:
In formula, r-bend mean radius; L-rear tread partly.
Simultaneous solution formula (1), formula (2), and establish
then can obtain:
Under the vehicle parameter determined and driving conditions, n
1, s, L be known.Therefore, n

During Turning travel, formula (3), formula (4) are substituted into formula (5) and obtain:
Order
Then formula (7) becomes:

And n
mincrease with r and increase, when r → 0, n
m→ 0; As r →+∞, n
m→ n
1, namely when radius of turn r level off to 0 time, the speed of a motor vehicle also levels off to 0; Radius of turn level off to infinity time (straight-line travelling), the speed of a motor vehicle levels off to n
1.Visible, differential mechanism of the present invention has the function of bend automatic retarding, and slowing effect is directly related with bend emergency degree, and vehicle travels safer.
The present invention can be widely used in all wheeled vehicles needing differential mechanism, as automobile, engineering vehicle etc.
