Bearing (7), screw (8), the second deep groove ball bearing (9), sleeve pad (11), the 3rd deep groove ball bearing (12) composition, its feature
It is：The planetary gear system of orthodox car differential mechanism is abandoned, instead " retainer -- rolling into block -- right axle shaft is double in external tooth
Phase cam ring " system, the system mainly include retainer (1) in external tooth, roll into block (5), left half axle centre wheel (2), right axle shaft
Two-phase cam ring (6), differential is realized with this system, forms differential mechanism；The outside of retainer (1) is straight bevel tooth in external tooth
Wheel, inside are tube-in-tube structures, and Z is circumferentially provided with along the tube-in-tube structure1Individual radial direction guide groove, in the guide groove built with rolling into block (5), therefore
The tube-in-tube structure is referred to as retainer, so retainer (1) is both a bevel gear of main reducing gear in external tooth, it is differential mechanism machine again
A component in structure, main reducing gear and differential mechanism are organically integrated by retainer (1) in external tooth, retainer in external tooth
(1) entirety is fixedly connected into by screw (8) and is supported on frame by a pair of taper roll bearings (3) with right half-shell (4)
On；The above-mentioned block (5) that rolls into be made up of backbone block (15), pin (16), needle roller (17), needle roller sleeve (18), sell (16) both ends and
It is tight fit between the hole of backbone block (15) both sides, four needle roller sleeves (18) support by pin (16) and pass through needle roller (17)
Formed with backbone block (15) and roll connecting relation；Left half axle centre wheel (2) is multiphase external cam, and the multiphase external cam is with more
The external gear of individual projection, the number of its concave portion are referred to as the number of teeth of left half axle centre wheel (2), are designated as Z2, outside the multiphase
The contour curve of cam is to roll into block (5) on the one hand to rotate with retainer in external tooth (1), another aspect and the retainer in external tooth
(1) in radial direction guide groove it is mobile during, a series of envelope of positions residing for its inner needle roller sleeve (18), in left half axle
Heart wheel (2) is embedded in the tube-in-tube structure of retainer in external tooth (1), and the left end of left half axle centre wheel (2) is left half axle, left half axle
Centre wheel (2) is fixedly connected with by left half axle and left side rear wheel (13), and the right-hand member of left half axle centre wheel (2) passes through the second deep-groove ball
Bearing (9) is supported within right axle shaft two-phase cam ring (6), and left end is supported in external tooth by the 3rd deep groove ball bearing (12) and protected
Hold within frame (1)；Right axle shaft two-phase cam ring (6) is two-phase cam ring, and the inside of the two-phase cam ring is double off-centre operations or ellipse
Circular two-phase cam ring, its own complete mass balance, the tube-in-tube structure of retainer (1) is embedded in right axle shaft two-phase in external tooth
Within cam (6), the right-hand member of right axle shaft two-phase cam ring (6) is right axle shaft, right axle shaft two-phase cam ring (6) by right axle shaft with
The right rear wheel (14) is fixed together, and right axle shaft two-phase cam ring (6) is supported on right half by a pair of first deep groove ball bearings (7)
In shell (4)；Roll into block (5) the needle roller sleeve (18) of centre two can in external tooth the tube-in-tube structure of retainer (1) radial guiding
Radially rolled on groove inwall, couple so that rolling between block (5) and retainer in external tooth (1) and forming to roll, roll into block (5)
The needle roller sleeve (18) at both ends and right axle shaft two-phase cam ring (6) and left half axle centre wheel (2) are meshed each composition one respectively
Roll higher pair；The tooth number Z of left half axle centre wheel (2)2With the number Z for rolling into block (5)1Difference be 2.
The operation principle of differential mechanism of the present invention is：When the driven wheel of differential of main reducing gear is retainer in external tooth (1)
When being driven and being rotated with constant angular velocity, the radial direction guide groove of retainer (1) produces thrust to rolling into block (5) in external tooth, rolls into block
(5) with left half axle centre wheel (2) and right axle shaft two-phase cam ring (6) and meanwhile contact engage and promote they rotate, at the same time
Block (5) is rolled into move in the radial direction guide groove of retainer (1) also in external tooth, it is left so as to form a two degrees of freedom differential system
Semiaxis centre wheel (2) and motion on right axle shaft two-phase cam ring (6) and power be then transmitted to respectively with its be fixedly connected with it is left and right after
Wheel.Right axle shaft two-phase cam ring (6) and left half axle centre wheel (2) rotate respectively in the presence of driving force, but respective fortune
Dynamic state is uncertain, is determined by the different road surface of left and right rear wheel, bend situation.When automobile on straight road linear rows
Sail, when the wheel on wheel and right axle shaft two-phase cam ring (6) on left half axle centre wheel (2) is without speed discrepancy, left half axle center
Wheel (2) is identical with the rotating speed of right axle shaft two-phase cam ring (6), i.e., differential mechanism does not have differential action.Now, each part in differential mechanism
Geo-stationary is kept, torque is inputted by retainer in external tooth (1), and left half axle centre wheel (2) and the right side are averagely transmitted to through rolling into block (5)
Semiaxis two-phase cam ring (6).Travelled when automobile turning or on rough road, when speed discrepancy occurs in the trailing wheel of left and right two, roll into block
(5) driven by retainer in external tooth (1), on the one hand drive left half axle centre wheel (2) and right axle shaft two-phase cam ring (6) to turn
It is dynamic, do in the radial direction guide groove of retainer (1) in external tooth while on the other hand retainer (1) rotates in external tooth and radially transport
It is dynamic, ensure that left half axle centre wheel (2) and right axle shaft two-phase cam ring (6) are able to realize differential in the case where not departing from transmission.
And due to rolling into work of the block (5) to torque caused by the active force of left half axle centre wheel (2) and right axle shaft two-phase cam ring (6)
With making that 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, external tooth is interior to be protected
The rotating speed for holding frame (1) is n1, then can be obtained by Fig. 9：
In formula, Z2The number of teeth of-left half axle centre wheel；Z1- roll into the number of block.
Such as setting automobile will turn left, and two front-wheels of automobile are in the presence of steering mechanism (Figure 10), its axis and automobile two
The axis of trailing 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,
The rotating speed of two trailing wheels should be directly proportional to turning radius, can be obtained by Figure 10：
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, n1、Z1、Z2, L be known.Therefore, n2With 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.
