Description

Pull-type self-aligning separable bearing of clutch assembly

Technical field

The utility model relates to a kind of automobile-use clutch release bearing assembly, especially relates to a kind of pull-type self-aligning separable bearing of clutch assembly that is used on medium-sized or the heavy vehicle.

Background technique

Usually the release bearing assembly of automobile-use mostly is the push-press type structure; but for medium-sized or heavy Motor Vehicle; because the driving torque of power is bigger; the Separating force required with the release bearing assembly of push-press type structure is bigger; operation is painstaking; easily cause the wearing and tearing of clutch and release bearing, and shorten its working life.And the pull type clutch release bearing assembly is because fulcrum is outer, have in the light characteristics of same Separating force lower-pilot, so for the more and more pull type clutch release bearings that adopt of the clutch of medium-sized and heavy vehicle, but pull type clutch release bearing, bearing outer ring directly is connected with release sleeve, therefore when the shaft axis disalignment of bearing axis and clutch, because release bearing and clutch can't be realized self-aligning, so can increase the friction of release bearing and clutch, and the wearing and tearing of acceleration release bearing, and can produce noise because of frictional force, shorten the working life of release bearing.

Summary of the invention

The purpose of this utility model provides a kind of can the adjusting automatically makes release bearing and clutch keep coaxial pull-type self-aligning separable bearing of clutch assembly.

The utility model is that the technological scheme that achieves the above object is: a kind of pull-type self-aligning separable bearing of clutch assembly, comprise bearing inner race, bearing outer ring, retainer and rolling element and release sleeve, it is characterized in that: its big shaft portion of bearing inner race that is multidiameter shaft is connected with bearing outer ring by retainer and rolling element, the little shaft portion of bearing inner race extends axially out bearing outer ring, little shaft end has cone angle, and the rear portion of cone angle also is provided with barb; Between bearing inner race and the bearing outer ring both sides seal ring is housed respectively, be fixed on butterfly spring on the release sleeve and withstand on the inner side surface of bearing outer ring, endoporus is embedded with on the release sleeve of wear-resistant sleeve and also is fixed with outer cover, the outer cover retaining provides precompression to butterfly spring on the outer side surface of bearing outer ring, be provided with the radial clearance that can regulate the axle center automatically between bearing outer ring and the release sleeve.

The utility model adopts the advantage after the technique scheme to be: owing to be provided with radial clearance between release sleeve and the bearing outer ring, and outer cover provides certain precompression to butterfly spring again, under the elastic force effect of butterfly spring, bearing outer ring is linked to each other all the time with release sleeve, under release bearing and clutch out-of-alignment situation, in the engaging process of clutch, the eccentric force that release bearing and clutch disalignment are produced is during greater than the elastic force of butterfly spring, just can carry out automatic compensation adjustment by this radial clearance, repeatedly joint through clutch, repeatedly compensate, make release bearing and clutch shaft keep coaxial, solved the problem that causes clutch and release bearing premature wear owing to release bearing and clutch disalignment, obviously improve the working life of release bearing and clutch, and reduced the running noise of release bearing.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to structural representation.

Embodiment

Pull-type self-aligning separable bearing of clutch assembly as shown in Figure 1, comprise bearing inner race 1, bearing outer ring 4, retainer 6 and rolling element 5 and release sleeve 8, bearing inner race 1 is multidiameter shaft, the big shaft portion of bearing inner race 1 is connected with bearing outer ring 4 by retainer 6 and rolling element 5, bearing inner race 1 little shaft portion extends axially out bearing outer ring 4, end at bearing inner race 1 little shaft portion has cone angle, and the rear portion that is positioned at cone angle also is provided with barb 1-1, as the unidirectional latch hook that separates draw ring is installed.For making release bearing have excellent sealing performance, bearing outer ring 4 all is equipped with seal ring 2 with bearing inner race 1 both sides, 11, one butterfly spring 7 is fixedly connected on the side of release sleeve 8, the opposite side of butterfly spring 7 withstands on the inner side surface of bearing outer ring 4, be fixed with outer cover 3 on the convex shoulder of release sleeve 8, outer cover 3 then retaining on bearing outer ring 4 outer side surfaces, outer cover 3 provides the precompression of setting for butterfly spring 7, be provided with the radial clearance 12 that to regulate the axle center automatically between bearing outer ring 4 and the release sleeve 8, this radial clearance 12 is between 0.5～1.5mm, when the eccentric force of clutch and release bearing during greater than the elastic force of butterfly spring 7, by the radial clearance 12 between bearing outer ring 4 and the release sleeve 8, release bearing is radially adjusted in release sleeve 8, reach the coaxial order of clutch and release bearing and.For increasing the working life of release sleeve 8, be embedded with wear-resistant sleeve 10 at release sleeve 8 endoporus, wear-resistant sleeve 10 can adopt engineering plastics to make.

See shown in Fig. 1,2, the wearing and tearing of release sleeve 8 are influenced the proper functioning of clutch 1, be provided with the lug of symmetry in the outside of release sleeve 8, and wear-resisting cushion block 9 is housed on the lug for reducing shift fork; Perhaps directly wear-resisting cushion block 9 is housed in the shaft shoulder place in release sleeve 8 outsides symmetry.

During the clutch proper functioning, under the elastic force effect of diaphragm spring, the master of clutch, passive wearing piece are engaged, when release bearing and clutch disalignment, its eccentric force overcomes the elastic force of butterfly spring 7, and then release bearing radially moves in release sleeve 8, by repeatedly adjusting automatically, make release bearing and clutch keep coaxial, power is exported by clutch; When shift fork was stirred release sleeve 8 outside clutch, release sleeve 8 drove release bearings and outwards moves along main shaft, and the separation draw ring that is connected on the bearing inner race also moves laterally, then diaphragm spring also moves thereupon, at this moment, the master of clutch, passive wearing piece separate, and cut off power output.
