Description
Technical field
The present invention relates to a kind of limited-slip differential, more particularly, to a kind of axial cam formula limited-slip differential.
Background technology
In Vehicle Engineering technology, the appearance of differential mechanism solves automobile in uneven road surface and steering to a left side well
The problem of right driving moment rotating speed different requirement, but it follows that the presence of differential mechanism causes automobile to be driven in side
Power can not be transmitted effectively when wheel skids.
Reason is the characteristics of torques such as differential mechanism has are distributed, when there is single wheel skidding, and opposite side wheel is obtained
Driving force also become very little, that is to say, that the wheel of skidding can not produce driving force, and non-slip wheel is not obtained
Enough moments of torsion, so that trafficability is deteriorated, then for this problem is solved, occur in that differential lock again.
Differential lock solves the problem of power that automobile occurs when single wheel skids is transmitted, that is, locking well
Differential mechanism, allows differential mechanism no longer to work, and the driving wheel of the left and right sides can obtain identical moment of torsion.However, differential lock is in solution
The problem of certainly bringing new again while original problem.Operationally wheel is unable to differential to differential lock, as a result often results in transmission
System failure.In order to solve this problem, limited-slip differential is occurred in that again, and limited-slip differential is that one kind that limiting wheel is slided is new
Type differential mechanism, it can be such that the rotating speed difference of both sides driving wheel is allowed within the specific limits, to ensure that vehicle is normally turned
And the normally travel under some other special road conditions.
Cam slide differential mechanism is one kind in numerous limited-slip differentials.It is using larger between cam and sliding block
Moment of friction makes the high friction self-locking formula differential mechanism of differential mechanism internal mechanism locking.Existing cam slide differential mechanism mainly has
Two kinds of radial cams sliding block differential mechanism and axial cam sliding block differential mechanism.
Radial cams sliding block differential mechanism is main by differential carrier, convex wheel body, evagination wheel body, sliding block separator, sliding block etc.
Composition, wherein interior external cam is connected by spline semiaxis with left and right wheelses respectively, vehicle power driving sliding block separator drives and slided
Block drives inside and outside cam rotation simultaneously, so as to drive vehicle wheel rotation.When left and right wheels differential is rotated, sliding block is between interior external cam
Diametrically reciprocated along cam curve, it is ensured that the realization of differential motion, under differential state, due to always having sliding block in engagement position
Put, sliding block remains to maintain the driving force to cam under frictional force effect, remains to keep high torque defeated in slow-speed of revolution side
Go out.But the differential mechanism of this structure, under limiting condition, in the case that single wheel is hanging, hanging wheel is it is possible to beat
It is sliding.
Existing axial cam sliding block differential mechanism, is mainly made up of housing, spider gear, sliding block.The front end of each spider gear
Face it is along the circumferential direction uniform multiple hills constitute edge cams, each hill is by equal, the oppositely oriented two ends spiral of pitch
Face is constituted, and each helicoid is in low inside and high outside heeling condition each along differential wheel radial.The side spider gear back side and housing it
Between be equipped with butterfly spring and pad.The small hill at sliding block between spider gear or so end matches with spider gear hill.
During differential motion, sliding block slides axially in the housing.And because the axial compressive force of butterfly spring is acted on, make sliding block two ends
Helicoid fits with the helicoid of spider gear all the time, so that it is poor to ensure that both sides vehicle is realized in the case where not departing from transmission
Speed.The obvious deficiency that the limited-slip differential of this structure is present is：It limits the realization of sliding function dependent on spider gear rear
Butterfly spring is applied to the axial compressive force at the spider gear back side, and in the case where road conditions are complicated, its Locking property can become very not
It is stable.Secondly, it is guarantee sliding block and the uniformity in cam contact area, the processing technology difficulty of respective cams and sliding block is larger,
Therefore its actual application effect is extremely difficult to be expected.
