The right-hand member of pedestal (2) is tube-in-tube structure, and Z is circumferentially provided with along the sleeve2Individual radial direction guide groove, the guide groove is left built with movable block (5)
Half pedestal (2) is supported in external tooth in multiphase cam ring (1) by a pair of deep groove ball bearings (13)；By right axle shaft and a centre wheel
Design is integrated, referred to as right axle shaft centre wheel (6), and the right-hand member of right axle shaft centre wheel (6) is right axle shaft, right axle shaft centre wheel (6)
It is fixed together, is taken turns centered on the left end of right axle shaft centre wheel (6) with the right wheel (15) by right axle shaft, the centre wheel is tool
There is the external cam of multiple concave portions, therefore right axle shaft centre wheel (6) is the external cam with multiple concave portions, its protuberance
The number divided is that the number of teeth is designated as Z6, the center wheel portion of right axle shaft centre wheel (6) is embedded in the right-hand member sleeve knot of left half axle frame (2)
In structure, the left end of right axle shaft centre wheel (6) is supported within left half axle frame (2) by deep groove ball bearing (9), and right-hand member passes through zanjon
Ball bearing (7) is supported within right half-shell (4)；Along footpath on the radial direction guide groove inwall of the right-hand member tube-in-tube structure of left half axle frame (2)
To the groove for being provided with to fill needle roller (10), in the groove built with some needle rollers (10), movable block (5) is mounted in left half axle frame
(2) in the radial direction guide groove of right-hand member sleeve, its can left half axle frame (2) radial direction guide groove central diameter to moving through in guide groove
Some needle rollers (10) and the radial direction guide groove composition of left half axle frame (2) roll annexation, and change sliding friction is rolling friction；Move
The upper and lower outer cylinder surface of motion block (5) respectively with the multiphase cam ring profile of multiphase cam ring (1) and right axle shaft center in external tooth
Wheel (6) external cam profile be meshed it is each composition one higher pair.The tooth number Z of right axle shaft centre wheel (6)6With the number of movable block (5)
Mesh Z2Difference be 3.
The operation principle of differential mechanism of the present invention is：
When the power of internal combustion engine is inputted by the active spur bevel gear (11) of main reducing gear, main reducing gear from mantle tooth
When wheel is that multiphase cam ring (1) is driven and rotated with constant angular velocity in external tooth, due to the multiphase of multiphase cam ring (1) in external tooth
Changing to footpath and producing thrust to movable block (5) for cam ring profile, forces movable block (5) in the radial guiding of left half axle frame (2)
Moved in groove and promote left half axle frame (2) to rotate, at the same time connect by the higher pair of movable block (5) and right axle shaft centre wheel (6)
Touching will also promote right axle shaft centre wheel (6) to rotate, so that a two degrees of freedom differential system is constituted, left half axle frame (2) and right half
The motion of axle centre wheel (6) and power are then transmitted to the left and right wheel being fixedly connected with it respectively.Right axle shaft centre wheel (6) and left half
Pedestal (2) is rotated respectively in the presence of driving force, but respective motion state be it is uncertain, it is different by left and right wheel
Road surface, bend situation are determined.Wheel and right axle shaft centre wheel when automobile on straight road on straight-line travelling, left half axle frame (2)
(6) when wheel on is without speed discrepancy, left half axle frame (2) is identical with the rotating speed of right axle shaft centre wheel (6), i.e., differential mechanism does not have differential
Effect.Now, each part keeps geo-stationary in differential mechanism, and torque multiphase cam ring (1) in external tooth is inputted, through movable block
(5) left half axle frame (2) and right axle shaft centre wheel (6) are averagely transmitted to.Travelled when automobile turning or on rough road, behind or so
When speed discrepancy occurs in two-wheeled, movable block (5) is driven by multiphase cam ring (1) in external tooth, on the one hand driving left half axle frame (2) and
Right axle shaft centre wheel (6) rotate, on the other hand while being rotated with left half axle frame (2) left half axle frame (2) radial direction guide groove
In radially move, it is ensured that left half axle frame (2) and right axle shaft centre wheel (6) be able to do not depart from transmission in the case of realize it is poor
Speed.And the effect due to movable block (5) to the torque of the active force generation of left half axle frame (2) and right axle shaft centre wheel (6), make
The bigger torque of the fast driving wheel of specific speed can be obtained on the slow driving wheel of rotating speed.
The differential property of differential mechanism to illustrate the invention, if left and right wheel speed is respectively n behind automobile2、n6, it is many in external tooth
The rotating speed of phase cam ring (1) is n1, then can be obtained by Fig. 7：
In formula, Z2The number of movable block one by one；Z6The number of teeth of right axle shaft centre wheel one by one.
Such as setting automobile will turn left, and two front-wheels of automobile are in the presence of steering mechanism (Fig. 8), after its axis and automobile two
The axis of wheel intersects at P points, and now can be considered whole automobile is around the revolution of 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. 8：
In formula, r bend mean radius one by one；L rear tread half one by one.
Simultaneous solution formula (1), formula (2), and setIt can then obtain：
It is determined that vehicle parameter and driving conditions under, n1, s, L be known.Therefore, n2With n6Only with radius of turn r
Become.Therefore differential mechanism of the present invention possesses differential function, the vehicle for equipping the differential mechanism can be by any half curve.
Investigate the mean speed of the vehicle both sides wheel of equipment differential mechanism of the present invention：
nM=0.5 (n6+n2) (5)
During straight-line travelling, n6=n2=n1, obtain：
nM=n1 (6)
During Turning travel, formula (3), formula (4) are substituted into formula (5) and obtained：
OrderThen formula (7) is changed into：
nM=Wn1 (8)
Usual s>1, W is known by formula (8)<1, therefore have：
nM＜ n1 (9)
And nMIncrease with r and increase, as r → 0, nM→0；As r →+∞, nM→n1, i.e., when radius of turn r levels off to
When 0, speed also levels off to 0；Radius of turn level off to infinity when (straight-line travelling), speed levels off to n1.It can be seen that, the present invention is poor
Fast utensil has the function of bend automatic retarding, and slowing effect is directly related with bend emergency degree, and vehicle traveling is safer.
Disclosed by the invention is widely suitable to differential mechanism in need wheeled vehicle, such as automobile, engineering truck.
