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, retainer (1) is driven and is rotated with constant angular velocity, in external tooth, the radial guide groove of retainer (1) produces thrust to rolling into block (5), roll into block (5) simultaneously to contact to engage and promote them with right axle shaft internal gear (6) higher pair with the heterogeneous external cam of left half axle (2) and rotate, meanwhile roll into block (5) also in external tooth retainer (1) radial guide groove in move, thus form a two degrees of freedom differential system, the heterogeneous external cam of left half axle (2) then passes to power the left side be connected mutually with it with the motion on right axle shaft internal gear (6) respectively, right rear wheel.Right axle shaft internal gear (6) and the heterogeneous external cam of left half axle (2) are rotated respectively under the effect of driving force, but respective motion state is uncertain, are determined by the different road surface of left and right rear wheel, bend situation.When automobile straight-line travelling on straight road, when wheel on wheel in the heterogeneous external cam of left half axle (2) and right axle shaft internal gear (6) is without speed discrepancy, the heterogeneous external cam of left half axle (2) is identical with the rotating speed of right axle shaft internal 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 retainer in external tooth (1), on average passes to the heterogeneous external cam of left half axle (2) and right axle shaft internal 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 retainer in external tooth (1), the heterogeneous external cam of left half axle (2) and right axle shaft internal gear (6) is driven to rotate on the one hand, on the other hand while rotating with retainer in external tooth (1) in external tooth retainer (1) radial guide groove in radially move, ensure that the heterogeneous external cam of left half axle (2) and right axle shaft internal 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 the heterogeneous external cam of left half axle (2) and right axle shaft internal 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
6, in external tooth, the rotating speed of retainer (1) is n
1, then can be obtained by Fig. 9:
In formula, Z
1one for rolling into the number of block; Z
6one is the number of teeth of right axle shaft internal gear.
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 mono-bend mean radius; L mono-rear tread partly.
Simultaneous solution formula (1), formula (2):
Under the vehicle parameter determined and driving conditions, n
1, Z
1, Z
6, L is known.Therefore, n
2with n
6only become with radius of turn r.Therefore differential mechanism of the present invention possesses differential function, the vehicle equipping this differential mechanism can by any half curve.
The present invention can be widely used in all wheeled vehicles needing differential mechanism, as automobile, engineering vehicle etc.
