The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of limited-slip differential, and it is by setting
Partition and friction plate realize two axle shaft gear Fast-Balances of differential mechanism, and effect is good, it is ensured that in road surface slippery situation, normal row
Sail, it is safe.
The scheme that the utility model solves the technical problem is：
A kind of limited-slip differential, including housing, are provided with central shaft, axle shaft gear, planetary gear in the housing, housing
The both ends that upper and lower part has semiaxis jack, central shaft are fixed on the left and right sides wall of housing, on the two ends of central shaft
Planetary gear is inserted with, the upper and lower part of housing is provided with axle shaft gear, and axle shaft gear is meshed with the planetary gear of both sides；
The interior side wall of the semiaxis jack has connecting groove, and the end sleeve of the connection axle portion of axle shaft gear is in housing
Top or bottom connecting groove in, connection axle portion be in housing in lateral wall on have outer toothed portion, friction plate and partition
Be disposed alternately between housing and connection axle portion, friction plate and partition sleeve in axle portion is connected, the interior teeth portion of friction plate and company
The outer toothed portion in spindle portion is meshed, and has multiple slots on the lateral wall of partition, and housing has with the corresponding madial wall of partition
There are multiple lug bosses, lug boss sleeve is in corresponding slot.
Oblique oil through is equipped with the planetary gear and axle shaft gear, one end of planetary oblique oil through is stretched
Go out planetary outside wall surface, the other end of planetary oblique oil through stretches out planetary internal face.
The lower end of the housing has been bolted to connection transmission gear ring.
The central axis of described two axle shaft gears is on the same line.
The central axis of described two axle shaft gears is perpendicular with the central axis of central shaft.
Prominent effect of the present utility model is：
Compared with prior art, it realizes two axle shaft gear quick flats of differential mechanism by the partition and friction plate that set
Weighing apparatus, effect is good, it is ensured that in road surface slippery situation, normally travel is safe.
Brief description of the drawings：
Fig. 1 is partial structural diagram of the present utility model；
Fig. 2 is the partial enlarged drawing between partition and housing.
Specific embodiment：
Embodiment, is shown in as shown in Figure 1 to Figure 2, a kind of limited-slip differential, including housing 10, in being provided with the housing 10
Heart axle 11, axle shaft gear 12, planetary gear 13, the upper and lower part of housing 10 have semiaxis jack 101, the two ends of central shaft 11
Portion is fixed on the left and right sides wall of housing 10, and the two ends upper sleeve of central shaft 11 has a planetary gear 13, the top of housing 10 and
Bottom is provided with axle shaft gear 12, and axle shaft gear 12 is meshed with the planetary gear 13 of both sides；
The interior side wall of the semiaxis jack 101 has connecting groove 102, the end of the connection axle portion 121 of axle shaft gear 12
In the connecting groove 102 of the top of housing 10 or bottom, connection axle portion 121 is on the lateral wall in housing 10 to be had portion's sleeve
There is outer toothed portion, friction plate 1 and partition 2 are disposed alternately between housing 10 and connection axle portion 121, and friction plate 1 and the sleeve of partition 2 exist
In connection axle portion 121, the interior teeth portion of friction plate 1 is meshed with the outer toothed portion for being connected axle portion 121, has on the lateral wall of partition 2
Multiple slots 21, housing 10 is with, with multiple lug bosses 14, the sleeve of lug boss 14 is corresponding on the corresponding madial wall of partition 2
In slot 21.
Further, oblique oil through 3 is equipped with the planetary gear 13 and axle shaft gear 12, planetary gear 13
The outside wall surface of planetary gear 13 is stretched out in one end of oblique oil through 3, and the other end of the oblique oil through 3 of planetary gear 13 stretches out row
The internal face of star gear 13.
Further, the lower end of the housing 10 has been bolted to connection transmission gear ring 4.
Further, the central axis of described two axle shaft gears 12 is on the same line.
Further, the central axis of described two axle shaft gears 12 is perpendicular with the central axis of central shaft 11.
Operation principle：When the rotating speed of two wheels in left and right of car has deviation, the fast axle shaft gear 12 of rotating speed to turn
The slow axle shaft gear 12 of speed has a centripetal force, so that two axle shaft gears 12 are leaned on to side, now, adjacent friction
Piece 1 and partition 2 are mutually pressed against, so that the rotating speed of axle shaft gear 12 is reduced, until after centripetal force loses, two axle shaft gears 12
Rotating speed is identical, realizes balance, and now, friction plate 1 and partition 2 are separated automatically, so as to realize normal operation.
Finally, embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, relevant skill
