Description
Technical field the present invention relates to a kind of differential mechanism, specifically is a kind of automobile differential with automatic latch functions.
Background technique
Differential mechanism is applied on the various types of vehicles, and the assurance vehicle can turn to different angular velocity and travel.Existing differential mechanism mainly is made up of housing, planetary pinion, differential gear, and differential gear is connected with driving wheel by semiaxis, and when travelling on better road surface, its performance all can satisfy normally travelling of automobile.But when automobile running during in bad road conditions, go-anywhere vehicle especially, in the rugged environment that travels usually in the open air, this has just had a strong impact on its traffic capacity.Such as one of them wheel over head and ears in the mire or when unsettled, though another wheel is in good road surface, but can not advance because skidding, because the adhesion on the wheel in the mire and ground is little at this moment, tire will dally, and can not get driving force with the hesive tire in ground because of the effect of differential mechanism, thereby automobile can not advance.If open the throttle this moment, not only can not deal with problems, and the waste fuel oil, and make the Tyte Wear aggravation; In order to address this problem, the claimant is provided with a differential mechanism that ends function with lock, as the patent No. be: 2005201027775, name is called: a kind of utility model patent that ends the differential mechanism of function with lock, one cover lockable mechanism is set in differential mechanism inside, but this latch functions needs outside pneumatic mechanism to cooperate, and structure is comparatively complicated.Summary of the invention
The object of the present invention is to provide a kind of automobile differential with automatic latch functions, adopted the fit system of clutch wheel, clutch axle sleeve and clutch post to realize the function of the differential running of differential mechanism and locking, need not start by external agency, have compact structure, automatically locking prevents the characteristics that wheel spin is skidded.
For achieving the above object by the following technical solutions:
A kind of automobile differential with automatic latch functions, comprise base and housing, it is characterized in that: the central authorities at described base have axis hole, side at axis hole is provided with the clutch seat, be provided with the post hole that several even distribution rounds are arranged at the clutch seat, in the post hole, be provided with the clutch post, be equipped with the clutch axle sleeve in axis hole inside, socket clutch wheel on the clutch seat, clutch axle sleeve, clutch wheel and the coaxial setting of clutch seat; Described clutch axle sleeve is connected with the semiaxis of automobile one side, is provided with clutch pinion in the corresponding post hole of outer side wall of clutch axle sleeve and the position of clutch post, and the clutch pinion outer rim is corrugated; The inwall of clutch wheel also is arranged to corrugated, the depression of undulatory clutch pinion outer rim and clutch wheel inwall or the quantity of lug boss are identical, described clutch pinion lug boss or depressed part are complementary with the clutch column length to the depressed part of corresponding clutch wheel inwall or the distance of lug boss, and the distance at clutch pinion outer rim and other position of clutch wheel inwall is less than the length of clutch post, also be provided with half-axile sleeve on clutch wheel, half-axile sleeve is connected with the semiaxis of automobile opposite side; The two ends of described clutch post are configured to the arc that matches with clutch pinion and clutch wheel inwall corrugated, and described housing is at the outside case that forms protection of clutch axle sleeve, clutch seat and clutch wheel.
The outside at described clutch seat also is socketed in retainer, and the retainer edge is the edge in post hole resistance shelves, has the otch that retainer cooperates at the cylinder of described clutch post, is provided with retainer in the stage casing of otch to cooperate projection.
Described clutch seat is provided with the post hole that two groups of rounds are arranged, and described clutch shaft puts and also is provided with two groups of clutch pinions, and lug boss or the depressed part of two groups of clutch pinions are interspersed, and it is identical that one group of depressed part is just located at the phase angle of the arc convex portion of next group.
Between two groups of post holes, the retainer edge hinders shelves with the edge in two groups of post holes simultaneously at described retainer.
Clutch axle sleeve, clutch wheel and clutch seat are in lockup state during original state of the present invention, because during automobile normal running, the linear velocity of automobile both sides wheel is identical, the clutch post is connected between clutch axle sleeve and the clutch wheel, and the both sides wheel keeps rotating synchronously; When automobile turning, the wheel linear velocity of automobile both sides changes, make clutch axle sleeve and clutch wheel rotating speed there are differences, the clutch axle sleeve of the very fast side of linear velocity or clutch wheel can be with the clutch capital to clutch wheel or clutch axle sleeves, make the two ends of clutch post be in lug boss and the depressed part of clutch pinion or clutch wheel inwall respectively, clutch pinion lug boss or depressed part are complementary with the clutch column length to the depressed part of corresponding clutch wheel inwall or the distance of lug boss, clutch this moment post is removed lockup state, clutch axle sleeve and clutch wheel are in separated state, and the both sides wheel can be realized turning by different linear velocities; And when a wheel wheel over head and ears in the mire or when unsettled wherein, this moment, wheel was not owing to be subjected to external drag or be subjected to resistance very little, both sides wheel unbalance stress, clutch axle sleeve and clutch wheel can be locked by the clutch post automatically, be in lockup state, avoid wheel over head and ears in the mire or when unsettled skidding to take place, the present invention need not be by external agency, automatically differential operation and locking automatically prevent that wheel spin from skidding.
