If multiple through holes 43 are used to install sliding block 3, two rows are divided into before and after through hole 43, per exhausting hole in radial equipartition；Open portion 42 is set with
In the periphery of 2 rear extension of active roller gear 27 and a gap is left, interior snap ring 7 is installed in the open inner ring of portion 42, outer snap ring 8
The open outer ring of portion 42 is installed in, the connecting portion 21 of active roller gear 2 is supported in the front end in the open portion 42 of separator (4).
As shown in Figure 3 and Figure 4, differential carrier 5 is also hollow " convex " word structure cover body, is supported mounted in the rear end of separator 4,
The canned paragraph 51 of its rear end protrusion is sheathed in rear through shaft 6 and is connected by spline and rear through shaft 6, rear through shaft 6
Axially align and do not contact with front through shaft 1；The front end of differential carrier 5 is column cover body section 52, canned paragraph 51 and cover body section 52
Between be intermediate incline 56, be respectively equipped with a circle lubrication hole 53 on the centre position of cover body section 52 and intermediate incline 56；Cover body section 52
The protuberance 41 in separator 4 is supported in rear end, left between the inner side of cover body section 52 and the open periphery of portion 42 of separator 4 gap to
Sliding block 3 is installed；The enclosure interior of cover body section 52 has the cover projection 55 and cover groove 54 (referring to Fig. 3) that uniform intervals are arranged, for
The upper prop of active roller gear 2 projection 23 and post groove 24 (referring to Fig. 4) form an annulus, make logical installed in separator 4
Sliding block 3 in hole 43 has a sliding space.
Referring to Fig. 5 (A is front view, and B is axonometric drawing), it with planar side and both ends is the cylindric of camber line that sliding block 3, which is,
Block, cylinder it is cylindrical on above and below cylinder mill out plane, plane central (i.e. non-milling to center respectively perpendicular to both ends camber line
To position) formed protrude from plane stop component 31 be used to limiting sliding block stroke (sliding block in the presence of stop component 31,
It can only be slided between interior snap ring 7 and outer snap ring 8)；The sagittal curvature design at cylinder both ends can be matched positioned at the inner side of separator 4
Post projection 23, post groove 24 and cover projection 55 positioned at the outside of separator 4, cover groove 54；Sliding block 3 has multiple, is divided into upper and lower two
Layer, in two exhausting holes 43 that the radially installed of sliding block 3 is laid in the front end opening portion 42 of separator 4, and by being respectively assembled at separation
The interior snap ring 7 and outer snap ring 8 of 4 front end opening portion of device, 42 inside and outside circle limit its radial motion, and interior snap ring 7 is arranged in separator 4
Between side and two layers of sliding block 3, outer snap ring 8 is arranged between the outside of separator 4 and two layers of sliding block 3.It is main in automobile rotation process
Dynamic roller gear 2 or the speed of differential carrier 5 are inconsistent, and when producing speed difference, sliding block 3 will be raised along the piece surface of speed bottom
It is relative with the curve of groove to slide, and because the curvilinear structures at the both ends of sliding block 3, sliding block radially turn under the drive of separator 4
During dynamic, the power of radial direction can be produced to active roller gear 2 and differential carrier 5, so as to realize differential.By the front end of separator 4
The inside and outside circle in open portion 42 loads onto interior snap ring 7, outer snap ring 8, by means of the retainer 31 between interior snap ring 7 and outer snap ring 8,
The stroke of sliding block 3 can be limited.
Assembling obtains the utility model radial slider formula between centers limited-slip differential above.During work, front through shaft 1 rotates,
The separator 4 being fixed in front through shaft 1 is driven to rotate；With reference to Fig. 2, it can be seen that, separator 4 rotates, and forces sliding block 3 radially
It is mobile, but due to the arcuate structure (rat and groove) on the inner ring of differential carrier 5 and the outer ring of active roller gear 2, make
Sliding block 3 with separator 4 when circumferencial direction rotates, can also give 2 one circumferencial directions of differential carrier 5 and active roller gear
Power, so as to drive differential carrier 5 and active roller gear 2 to rotate, and then drive 6 turns of the rear through shaft fixed with differential carrier 5
Dynamic, such front through shaft 1 and rear through shaft 6 rotate together, realize the power transmission of front-rear axle.
When automobile turning, because the angular speed of front and back wheel is different, so as to the front through shaft 1 related to front vehicle wheel and with
The rotating speed of the related rear through shaft 6 of rear wheel is different so that and the power that the inner ring of differential carrier 5 and active roller gear 2 are received is different, from
And produce rotary speed difference.Separator 4 with movable slider 3 while circumferencial direction rotates, sliding block 3 and the inner ring of differential carrier 5 and
Active roller gear 2 produces sliding friction, does radial motion.
When the jackshaft or back axle of automobile have one it is hanging or when being absorbed in muddy road surface, the hanging wheel of jackshaft or back axle will
Do not stress, in the presence of differential mechanism, hanging wheel will fly to turn.But sliding block 3 and differential mechanism under high speed differential state
The inner ring of shell 5 and active roller gear 2 produce sliding friction, and this friction can produce an opposite effect power, act on again
On the inner ring of differential carrier 5 or active roller gear 2, make the inner ring of differential carrier 5 or active roller gear 2 by circumferencial direction
Power, so as to also with rotation so that not hanging wheel continues dynamic traveling and realizes the sliding function of limit.
It will be appreciated by those skilled in the art that these embodiments are merely to illustrate the utility model without limiting this practicality newly
The scope of type, the various equivalent variations made to the utility model and modification belong to the utility model disclosure.
