The working principle of differential mechanism of the present invention is: when in the driven wheel of differential and external tooth of main reducing gear, central gear (1) is driven and rotates with constant angular velocity, because the internal gear of central gear in external tooth (1) produces thrust to portable sleeve roller (5), force portable sleeve roller (5) to be moved in the radial guide groove of left half axle frame (2) and promote left half axle frame (2) and rotate, meanwhile to be contacted with the higher pair of the heterogeneous external cam of right axle shaft (6) by portable sleeve roller (5) and also will promote the heterogeneous external cam of right axle shaft (6) 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 in the heterogeneous external cam of right axle shaft (6) respectively, right wheel.The heterogeneous external cam of right axle shaft (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 wheels, bend situation.When automobile straight-line travelling on straight road, when wheel in wheel on left half axle frame (2) and the heterogeneous external cam of right axle shaft (6) is without speed discrepancy, left half axle frame (2) is identical with the rotating speed of the heterogeneous external cam of right axle shaft (6), and namely differential mechanism does not have differential action.Now, in differential mechanism, each parts keep geo-stationary, and torque is inputted by central gear in external tooth (1), on average passes to left half axle frame (2) and the heterogeneous external cam of right axle shaft (6) through portable sleeve roller (5).Travel when automobile turning or on rough road, when there is speed discrepancy in left and right two-wheeled below, portable sleeve roller (5) ordering about by central gear in external tooth (1), left half axle frame (2) and the heterogeneous external cam of right axle shaft (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 the heterogeneous external cam of right axle shaft (6) are able to realize differential when not departing from transmission.And because portable sleeve roller (5) is to the effect of the moment that the active force of left half axle frame (2) and the heterogeneous external cam of right axle shaft (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
