Abstract

The utility model relates to a simple pull-type self-aligning clutch release bearing assembly which comprises a bearing inner ring, a bearing outer ring, a retainer, a rolling body, a release sleeve and a butterfly spring, wherein the bearing inner ring, the shaft end of which is provided with a clamping groove, is connected with the bearing outer ring through the retainer and the rolling body; sealing rings are arranged among both sides of each of the bearing inner ring and the bearing outer ring; the butterfly spring is arranged between the inner side face of the bearing outer ring and the side face of a shaft shoulder of the release sleeve an inner hole of which is provided with an abrasion resistant sleeve; one side of the bearing outer ring positioned on the release sleeve is also provided with a baffle ring, the inner diameter of which is greater than the outer diameter of the shaft shoulder of the release sleeve; a radial clearance which can automatically regulate the shaft center is arranged between the inner diameter of the baffle ring of the bearing outer ring and the outer diameter of the shaft shoulder of the release sleeve; the baffle ring of the bearing outer ring provides pre-press for the butterfly spring through a clamp spring. When a clutch is engaged, the elastic force of the butterfly spring is overcome so as to cause the release bearing to make radial regulation and compensation correspondingly to the release sleeve so that the purpose that the clutch and the release bearing are coaxial is realized and the service life of the release bearing and the clutch is extended.

Description

Simple and Easy Draw Type Self-Adjust Clutch Release Bearing Assembly

Technical field

The utility model relates to a kind of automobile-use clutch release bearing assembly, especially relates to a kind of Simple and Easy Draw Type Self-Adjust Clutch Release Bearing Assembly that is used on medium-sized or the heavy vehicle.

Background technique

The employed pull-type self-aligning separable bearing of clutch assembly of medium-sized or heavy vehicle, be between release sleeve and bearing outer ring, to be provided with radial clearance, and provide certain precompression to butterfly spring by outer cover, 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, elastic force by butterfly spring carries out automatic compensation adjustment to gap radially, make release bearing and clutch shaft keep coaxial, solution causes the problem of clutch and release bearing premature wear because of release bearing and clutch disalignment, to improve the working life of release bearing and clutch, and reduced the running noise of release bearing, but disclosed self-aligning separable bearing of clutch is to provide precompression by bearing outer ring to butterfly spring with outer cover, requires outer cover to be connected on the release sleeve securely.

Summary of the invention

The purpose of this utility model provides a kind of Simple and Easy Draw Type Self-Adjust Clutch Release Bearing Assembly that precompression directly is provided to butterfly spring by bearing outer ring.

The utility model is that the technological scheme that achieves the above object is: a kind of Simple and Easy Draw Type Self-Adjust Clutch Release Bearing Assembly, comprise bearing inner race, bearing outer ring, retainer, rolling element and release sleeve and butterfly spring, the bearing inner race that axle head is provided with draw-in groove is connected with bearing outer ring by retainer and rolling element, and between bearing inner race and the bearing outer ring both sides seal ring is housed respectively, endoporus is embedded with between the inner side surface of the side of its shaft shoulder of release sleeve of wear-resistant sleeve and bearing outer ring and is provided with butterfly spring, described bearing outer ring is positioned at release sleeve one side and also has baffle ring greater than release sleeve shaft shoulder external diameter, be provided with the radial clearance that can regulate the axle center automatically between the baffle ring internal diameter of bearing outer ring and the release sleeve shaft shoulder external diameter, the baffle ring of bearing outer ring provides precompression by jump ring to butterfly spring.

The utility model has been simplified processing and assembly technology owing to directly give the certain precompression of butterfly spring by bearing outer ring, connects reliable.

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.

Wherein: the 1-bearing inner race; The 2-seal ring; The 3-jump ring; The 4-bearing outer ring; The 4-1-baffle ring; The 5-rolling element; The 6-retainer; The 7-butterfly spring; The 8-seal ring; The 9-release sleeve; The 9-1-shaft shoulder; The 10-wear-resistant sleeve.

Embodiment

Simple and Easy Draw Type Self-Adjust Clutch Release Bearing Assembly as shown in Figure 1, comprise bearing inner race 1, bearing outer ring 4, retainer 6 and rolling element 5 and release sleeve 9, 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, the little shaft portion of bearing inner race 1 extends axially out bearing outer ring 4, has draw-in groove in bearing inner race 1 outside 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, 8, one butterfly spring 7 is arranged between the inner side surface of the side of release sleeve 9 shaft shoulder 9-1 and bearing outer ring 4, bearing outer ring 4 is positioned at release sleeve 9 one sides and also has baffle ring 4-1 greater than release sleeve 9 shaft shoulder 9-1 external diameters, be provided with the radial clearance that to regulate the axle center automatically between the shaft shoulder 9-1 external diameter of the baffle ring 4-1 internal diameter of bearing outer ring 4 and release sleeve 9, the baffle ring 4-1 of bearing outer ring 4 provides precompression by jump ring 3 to butterfly spring 7, this single face radial clearance 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 between bearing outer ring 4 and release sleeve 9 shaft shoulder 9-1, make release bearing do radially to adjust with respect to release sleeve 9, reach the coaxial purpose of clutch and release bearing, for increasing the working life of release sleeve 9, be embedded with wear-resistant sleeve 10 at release sleeve 9 endoporus, wear-resistant sleeve 10 can adopt engineering plastics to make.

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 moves radially with respect to release sleeve 9, by repeatedly adjusting automatically, make release bearing and clutch keep coaxial, power is exported by clutch; When shift fork was stirred release sleeve 9 outside clutch, release sleeve 9 drove release bearings and outwards moves along main shaft, and the separation draw ring that is connected on the bearing inner race 1 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.
