Description
Technical field
The present invention relates to a kind of differential mechanism, specifically a kind of automobile differential with automatic locking function.
Background technique
Differential mechanism is applied in various types of vehicles, ensures that vehicle can with different angular velocity Turning travel.Existing differential mechanism is primarily of housing, planetary pinion, differential gear composition, and differential gear is connected with driving wheel by semiaxis, and when travelling on better road surface, its performance all can meet the normal traveling of automobile.But when automobile running is in bad road conditions, especially go-anywhere vehicle, usually travel in the wild in rugged environment, this has just had a strong impact on its traffic capacity.During such as one of them wheel is over head and ears muddy or time unsettled, although another wheel is in good road surface, but can not advance because of skidding, because the wheel in now muddy and the adhesion on ground little, tire will dally, and can not get driving force with the hesive tire in ground because of the effect of differential mechanism, thus automobile can not advance.If now opened the throttle, not only can not deal with problems, and waste fuel oil, and the wearing and tearing of tire are aggravated; In order to address this problem, claimant is provided with the differential mechanism of a locking function, as the patent No. is: 2005201027775, name is called: a kind of utility model patent of differential mechanism of locking function, in differential mechanism inside, a set of lockable mechanism is set, but this latch functions needs outside pneumatic mechanism to coordinate, 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 locking function, the fit system that have employed clutch wheel, clutch axle sleeve and clutch post operates and the function of locking to the differential realizing differential mechanism, need not start by external agency, there is compact structure, feature that automatic locking prevents wheel spin from skidding.
For achieving the above object by the following technical solutions:
A kind of automobile differential with automatic locking function, comprise base and housing, it is characterized in that: have axis hole in the central authorities of described base, clutch seat is provided with in the side of axis hole, clutch seat is provided with the post holes that several are uniformly distributed round arrangement, in post holes, is provided with clutch post, has clutch axle sleeve at axis hole accommodated inside, clutch seat is socketed clutch wheel, and clutch axle sleeve, clutch wheel and clutch seat are coaxially arranged; Described clutch axle sleeve is connected with the semiaxis of automobile side, and the outer side wall correspondence post holes of clutch axle sleeve and the position of clutch post are provided with clutch pinion, and clutch pinion outer rim is corrugated; The inwall of clutch wheel is also arranged to corrugated, lug boss or the depressed part quantity of the depressed part of corrugated clutch pinion outer rim or lug boss and corrugated clutch wheel inwall are identical, described clutch pinion lug boss or depressed part match to the corresponding depressed part of clutch wheel inwall or the distance of lug boss and clutch column length, and the distance at clutch pinion outer rim and other position of clutch wheel inwall is less than the length of clutch post, clutch wheel is also provided with half-axile sleeve, and half-axile sleeve is connected with the semiaxis of automobile opposite side; The two ends of described clutch post are configured to the arc matched with clutch pinion and clutch wheel inwall corrugated, and described housing forms the case of protection in clutch axle sleeve, clutch seat and clutch wheel outside.
The outside of described clutch seat is also socketed with retainer, and retainer edge, by the edge barrier of post holes, the cylinder of described clutch post has the otch that retainer coordinates, is provided with coordinates projection with retainer in the stage casing of otch.
Described clutch seat is provided with the post holes of two groups of round arrangements, described clutch shaft puts and is also provided with two groups of clutch pinions, lug boss or the depressed part of two groups of clutch pinions are interspersed, and the phase angle in the arc convex portion of next group is just identical with the phase angle of upper one group of depressed part.
At described retainer between two groups of post holes, retainer edge is simultaneously by the edge barrier of two groups of post holes.
During original state of the present invention, clutch axle sleeve, clutch wheel and clutch seat are in lockup state, and during due to automobile normal running, the linear velocity of automobile both sides wheel is identical, and clutch post is connected between clutch axle sleeve and clutch wheel, and both sides wheel keeps synchronous axial system, when automobile turning, the wheel line speed of automobile both sides changes, clutch axle sleeve and clutch wheel rotating speed be there are differences, the clutch axle sleeve of the very fast side of linear velocity or clutch wheel can by clutch capital to clutch wheel or clutch axle sleeves, the two ends of clutch post are made to be in lug boss and the depressed part of clutch pinion or clutch wheel inwall respectively, clutch pinion lug boss or depressed part match to the corresponding depressed part of clutch wheel inwall or the distance of lug boss and clutch column length, now lockup state removed by clutch post, clutch axle sleeve and clutch wheel are in separated state, both sides wheel can realize turning by different linear velocities, and when wheel wherein a wheel over head and ears muddy in or unsettled time, now wheel is very little owing to not being subject to external drag or being subject to resistance, both sides wheel unbalance stress, clutch axle sleeve and clutch wheel can be automatically locked by clutch post, be in lockup state, in avoiding wheel over head and ears muddy or time unsettled, skidding occurs, the present invention need not by external agency, automatic differential runs and automatic locking, prevents wheel spin from skidding.
