Description
Technical field
The utility model belongs to the tractor field, relates to a kind of used with tractor friction plate self adaption limited slip differential.
Background technique
As far back as the sixties in 20th century, for power character and the control stability that improves racing car, the external existing example that adopts limited slip differential, and paid attention to vehicle is carried out research and experiment with limited slip differential.Because limited slip differential can effectively improve the usability of tractor, so at home and abroad the tractor industry obtains more and more widely application, it helps to improve power character, control stability, passing ability, the Security of tractor, smoothness etc.The tractor that has installed limited slip differential additional is changed little for differential design, self cost is low, but can improve hauling ability, acceleration performance and control stability and the driving safety of tractor greatly, and this has increased the competitiveness of product in market undoubtedly.
Farm tractor adopts compensating gear simple in structure mostly, and its locking coefficient is about 1.11-1.35.When the condition of adhering to of a driving wheel of tractor is very poor, common differential mechanism only allows the wheel on left and right both sides to reach the moment of torsion that the low coefficient of friction road surface can produce, if the moment of torsion that motor transmits is excessive, just the tire of low coefficient of friction skids, the car phenomenon may take place to fall in tractor.Therefore, design and a kind ofly can overcome the shortcoming that open differential skids easily because of locking coefficient is low, the used with tractor differential mechanism that improves anti-slide performance is the problem that the user is concerned about.
The model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, and uses reliably, can overcome the shortcoming that open differential skids easily because of locking coefficient is low, improves the used with tractor friction plate self adaption limited slip differential of anti-slide performance.
The technical solution of the utility model is: used with tractor friction plate self adaption limited slip differential mainly comprises: differential mechanism upper shell 10, differential mechanism lower shell body 5, differential pinion gear 9, differential mechanism stator 2, differential mechanism friction plate 3, differential side gear 4.External tooth and differential mechanism upper shell 10 with differential mechanism stator 2, the teeth groove of lower shell body 5 connects, the splined hole of differential mechanism friction plate 3 is connected with the spline tooth of differential side gear 4, differential side gear 4, differential mechanism stator 2, after differential mechanism friction plate 3 mutual intersections install, be respectively installed to differential mechanism upper shell 10, in the matching hole of lower shell body 5, two differential pinion gears 9 will be housed, the differential spider pinion shaft 8 of planetary pinion thrust washer 6 is installed to two semicircle axis hole places of differential mechanism upper shell 10, with 10～14 hexagon socket cap head screws 1 mounted differential mechanism upper shell 10, lower shell body 5 links together, and is fixed with planet wheel shaft pin 7.
The beneficial effects of the utility model are: add friction element on the basis of simple gears differential mechanism, by increasing the interior friction square of differential mechanism, can realize the differential locking function as required automatically, do not need the driver any auxiliary.This differential design compactness, smoothly noiseless during work, especially the versatility with common cone planetary gear differential mechanism part is good, and modification is convenient.And with low cost, manufacturing process is simple.
Description of drawings
Accompanying drawing is the structural representation of the utility model used with tractor friction plate self adaption limited slip differential.
Embodiment
As shown in drawings, used with tractor friction plate self adaption limited slip differential mainly comprises: differential mechanism upper shell 10, differential mechanism lower shell body 5, differential pinion gear 9, differential mechanism stator 2, differential mechanism friction plate 3, differential side gear 4.The external tooth of differential mechanism stator 2 and differential mechanism upper shell 10, the teeth groove of lower shell body 5 connects, the splined hole of differential mechanism friction plate 3 is connected with the spline tooth of differential side gear 4, differential side gear 4, differential mechanism stator 2, after differential mechanism friction plate 3 mutual intersections install, be respectively installed to differential mechanism upper shell 10, in the matching hole of lower shell body 5, two differential pinion gears 9 will be housed, the differential spider pinion shaft 8 of planetary pinion thrust washer 6 is installed to two semicircle axis hole places of differential mechanism upper shell 10, with 10～14 hexagon socket cap head screws 1 mounted differential mechanism upper shell 10, lower shell body 5 links together, and is fixed with planet wheel shaft pin 7.
The differential mechanism stator 2 at differential side gear 4 back sides, differential mechanism friction plate 3 during state of rest, the external tooth of differential mechanism stator 2 and differential mechanism upper shell 10, the teeth groove on the lower shell body 5 matches; The differential mechanism friction plate 3 that has splined hole matches with the spline tooth of differential gear 4.Differential gear 4, differential pinion gear 9, differential mechanism stator 2, differential mechanism friction plate 3 all can be done small moving axially.
Can carry out work as required fast and automatically during the real work of friction plate self adaption limited slip differential, and not need the driver any auxiliary.This locking effect is to be realized by the multi-disc differential mechanism stator 2, the differential mechanism friction plate 3 that are arranged symmetrically in differential mechanism upper shell 10, the lower shell body 5.When left and right sidesing driving wheel produced speed discrepancy, the active force that is produced during the transfer drive torque made the inclined-plane of differential pinion gear 9 produce axial force.The axial force that produces acts on differential mechanism stator 2, the differential mechanism friction plate 3 by differential gear 4, makes it produce axial motion along differential gear 4.Because the differential mechanism stator 2 of outer gearing combines with differential mechanism upper shell 10, lower shell body 5, and differential mechanism friction plate 3 meshes with differential gear 4, so the relative movement of 5 of differential gear 4 and differential mechanism upper shell 10, lower shell bodys is very difficult.Make differential mechanism lose differential action.Differential gear 4, differential mechanism stator 2, differential mechanism friction plate 3 set back gradually when left and right sidesing driving wheel does not produce speed discrepancy, and differential mechanism recovers differential function.
The size of axial force is determining the size of the video disc self-locking moment of torsion relevant with load, and self-locking moment of torsion and input torque remain proportionate relationship, that is to say that input torque remains with output torque proportional by stable self-locking action.Therefore, self-locking effect adapts to Engine torque voluntarily and changes and different gear torque variations.
