The operation principle of differential mechanism of the present invention is：
When the driven wheel of differential of main reducing gear is that retainer bevel gear (3) is driven and with constant angular velocity n3(ginseng during rotation
See Fig. 1), the axial channel of retainer bevel gear (3) produces thrust, spherical oscillating tooth (4) while and center to spherical oscillating tooth (4)
Internal gear (1) and the contact of three tooth difference slot type shock wave wheels (2) are engaged and promote them respectively with rotating speed n1、n2Rotate, at the same time ball
Shape oscillating tooth (4) also moves in the axial channel of retainer bevel gear (3), so as to form a two degrees of freedom differential system, in
Intracardiac gear (1) and motion on three tooth difference slot type shock wave wheels (2) and power are then transmitted to the left half axle mutually connected firmly with it respectively
(5), right axle shaft (6), and it is finally transmitted to left side wheel (13), the right wheel (14).Central inner gear (1) and three tooth difference slot types
Shock wave wheel (2) rotates respectively in the presence of driving force, but respective motion state is uncertain, by left and right rear wheel difference
Road surface, bend situation determine.When automobile, straight-line travelling, left side wheel (13) turn with the right wheel (14) nothing on straight road
During speed difference, Central inner gear (1) is identical with the rotating speed of three tooth difference slot type shock wave wheels (2), i.e., differential mechanism does not have differential action.This
When, each part keeps geo-stationary in differential system, and torque is inputted by retainer bevel gear (3), average through spherical oscillating tooth (4)
It is transmitted to Central inner gear (1) and three tooth difference slot type shock wave wheels (2).Travelled when automobile turning or on rough road, behind the left side
When wheel (13) speed discrepancy occurs with the right wheel (14), spherical oscillating tooth (4) is driven by retainer bevel gear (3), on the one hand
Central inner gear (1) and the rotation of three tooth difference slot type shock wave wheels (2) are driven, is on the other hand being rotated with retainer bevel gear (3)
Do in the axial channel of retainer bevel gear (3) and axially and radially move simultaneously, ensure that Central inner gear (1) and three teeth are poor
Slot type shock wave wheel (2) is able to realize differential in the case where not departing from transmission.And due to the intracardiac tooth of spherical oscillating tooth (4) centering
The effect of torque caused by the active force of (1) and three tooth difference slot type shock wave wheels (2) is taken turns, makes to obtain on the slow driving wheel of rotating speed
The bigger torque of the fast driving wheel of specific speed.
The differential property of differential mechanism to illustrate the invention, if left and right wheel speed is respectively n behind automobile5、n6, retainer cone
The rotating speed of gear (3) is n3, then can be obtained by Fig. 5：
In formula, Z3--- the spherical oscillating tooth number of teeth；Z1--- the number of teeth of Central inner gear.
Such as setting automobile will turn left, and two front-wheels of automobile are in the presence of steering mechanism (Fig. 6), after its axis and automobile two
The axis of wheel intersects at P points, and now can be considered whole automobile is turned round around P points.In the case where wheel and ground are non-slip, two
The rotating speed of trailing wheel should be directly proportional to turning radius, can be obtained by Fig. 6：
In formula, r --- bend mean radius；L --- rear tread half.
Simultaneous solution formula (1), formula (2), are obtained：
It is determined that vehicle parameter and driving conditions under, n3、Z1、Z3, L be known.Therefore, n5With n6Only with radius of turn
R and become.Therefore differential mechanism of the present invention possesses differential function, the vehicle for equipping the differential mechanism can be by any half curve.
Disclosed by the invention is widely suitable to differential mechanism in need wheeled vehicle, such as automobile, engineering truck.
