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 two roller block (5), two roller block (5) contacts to engage and promote them with right axle shaft central gear (6) higher pair with left half axle two-phase external cam (2) simultaneously and rotates, meanwhile two roller block (5) also in external tooth retainer (1) radial guide groove in move, thus form a two degrees of freedom differential system, motion on left half axle two-phase external cam (2) and right axle shaft central gear (6) and power then pass to the left side be connected with it respectively, right rear wheel.Right axle shaft central gear (6) and left half axle two-phase external cam (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 left half axle two-phase external cam (2) and right axle shaft central gear (6) is without speed discrepancy, left half axle two-phase external cam (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 retainer in external tooth (1), on average pass to left half axle two-phase external cam (2) and right axle shaft central gear (6) through two roller block (5).Travel when automobile turning or on rough road, when there is speed discrepancy in left and right two-wheeled below, two roller blocks (5) ordering about by retainer in external tooth (1), left half axle two-phase external cam (2) and right axle shaft central 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 left half axle two-phase external cam (2) and right axle shaft central gear (6) are able to realize differential when not departing from transmission.And because two roller block (5) is to the effect of the moment that the active force of left half axle two-phase external cam (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
6, in external tooth, the rotating speed of retainer (1) is n
1, then can be obtained by Fig. 9:
In formula, Z
1the number of a pair of roller block; Z
6the number of teeth of one right axle shaft central 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.
