It is the high hardness alloy piece that metal described in the technical solution of the present utility model is inserted.
Release bearing described in the technical solution of the present utility model is angular contact bearing.
The internal diameter of the baffle ring described in the technical solution of the present utility model cooperates with the external diameter that separates axle sleeve, and described inner draw-in groove has up big and down small stepped ramp type trepanning.
Elasticity platen described in the utility model is that roudnel is sunflower-shaped, is located on the little external diameter of baffle ring, mainly plays the effect of aligning pretightening force.
The utility model separates axle sleeve owing to adopt the PA66+GF50+1%MoS2 material to make, thereby can realize that casting once finishes, simplify loaded down with trivial details machining program, improving machining accuracy, reduce cost of material, alleviating bearing unit weight, reduce bearing noise aspect and played very big effect.The utility model is owing to be positioned at the metal that the position that cooperates with clutch shifter is provided with the outer end draw-in groove and snaps in the outer end draw-in groove and insert separating the opposing end face in axle sleeve and outer ring, thereby can remedy the deficiency of PA66+GF50+1%MoS2 material hardness, make the PA66+GF50+1%MoS2 material separate axle sleeve and substitute cast iron fully and separate axle sleeve.The utility model is owing to be provided with certain interval at the external diameter that separates axle sleeve and the endoporus of release bearing, thereby the release bearing rotating center can be adjusted automatically with respect to the declutch shaft cover.The utlity model has and to satisfy the anti-year wear-resisting requirement of clutch release bearing, can make the clutch release bearing unit weight reduce by 80% again, have self-lubricating property simultaneously, can reduce the noise in the bearing separation rotary course, improve vehicle riding comfort, the characteristics that increase the service life.The utility model is mainly used in lightweight self-aligning separable bearing of clutch unit.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated.
As shown in Figure 1 to Figure 3, the release bearing unit in the utility model specific embodiment comprises and separates axle sleeve 1, release bearing 2.Wherein, separate axle sleeve 1 and mainly comprise the metal 1-1 that inserts, inner draw-in groove 1-2, keyway 1-3, gain 1-4.Release bearing 2 mainly comprises outer ring 2-1, inner ring 2-2, steel ball 2-3, retainer 2-4, seal ring 2-5.Link mainly comprises clip 3, elasticity platen 3-1, baffle ring 3-2.Separating axle sleeve 1 is the separation axle sleeve of PA66+GF50+1%MoS2 material.Release bearing 2 is angular contact bearing.Inner draw-in groove 1-2 is positioned at and separates axle sleeve 1 end adjacent with outer ring 2-1, and clip 3 is loaded in the inner draw-in groove 1-2, for separating of being connected between axle sleeve 1 and the release bearing 2.Elasticity platen 3-1 is that roudnel is sunflower-shaped, is located on the little external diameter of baffle ring 3-2, mainly plays the effect of aligning pretightening force.The internal diameter of baffle ring 3-2 cooperates with the external diameter that separates axle sleeve 1, and inner draw-in groove tool 1-2 has up big and down small stepped ramp type trepanning.Separate and to be positioned at metal that the position that cooperates with clutch shifter is provided with the outer end draw-in groove and snaps in the outer end draw-in groove 1-1 that inserts on the opposing end face of axle sleeve 1 and outer ring 2-1, the metal 1-1 that inserts is the high hardness alloy piece, Chilled Hardened Steel such as high hardness alloy piece employing 45# steel are made, metal 1-1 shape such as the metal garden ring cushion block of inserting is two of being symmetrically distributed.Separating the external diameter of axle sleeve 1 and the endoporus of release bearing 2 has certain interval, gets so that declutch shaft cover and release bearing are realized aligning at work.
Feature with said modules structure, its assembling and use state are as follows:
