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 rotates with constant angular velocity, in external tooth, the radial guide groove of retainer (1) produces thrust to portable sleeve roller (5), portable sleeve roller (5) contacts to engage and promote them with the heterogeneous cam ring of right axle shaft (6) higher pair with left half axle central gear (2) simultaneously and rotates, meanwhile portable sleeve roller (5) also in external tooth retainer (1) radial guide groove in move, thus form a two degrees of freedom differential system, left half axle central gear (2) then passes to power the left side be connected mutually with it with the motion on the heterogeneous cam ring of right axle shaft (6) respectively, right wheel.The heterogeneous cam ring of right axle shaft (6) and left half axle central gear (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 on wheel on left half axle central gear (2) and the heterogeneous cam ring of right axle shaft (6) is without speed discrepancy, left half axle central gear (2) is identical with the rotating speed of the heterogeneous cam ring 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 retainer in external tooth (1), on average passes to left half axle central gear (2) and the heterogeneous cam ring 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 retainer in external tooth (1), left half axle central gear (2) and the heterogeneous cam ring of right axle shaft (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 central gear (2) and the heterogeneous cam ring 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 central gear (2) and the heterogeneous cam ring 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 2, n 6, in external tooth, the rotating speed of retainer (1) is n 1, then can be obtained by Fig. 7:
n 1 - n 6 n 2 - n 6 = Z 2 Z 1 - - - ( 1 )
In formula, Z 1the number of one portable sleeve roller; Z 2the number of teeth of one left half axle central gear.
As established automobile to turn left, two front-wheels of automobile are under the effect of steering equipment (Fig. 8), 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 Fig. 8:
n 2 n 6 = ( r - L ) ( r + L ) - - - ( 2 )
In formula, r mono-bend mean radius; L mono-rear tread partly.
Simultaneous solution formula (1), formula (2):
n 2 = ( r - L ) Z 1 Z 1 r + ( Z 1 - 2 Z 2 ) L n 1 - - - ( 3 )
n 6 = ( r + L ) Z 1 Z 1 r + ( Z 1 - 2 Z 2 ) L n 1 - - - ( 4 )
Under the vehicle parameter determined and driving conditions, n 1, Z 1, Z 2, 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.
