Abstract

The utility model relates to an automobile part, more specifically a special bearing for automobile clutches. According to the design proposal provided by the utility model, a steel ball is arranged between an inner ring with an L-shaped section and an outer ring with an L-shaped section, wherein the inner ring and the outer ring are respectively freely sheathed outside a lining; a gap is remained between the outer ring and the lining; one edge of a reed with an L-shaped section is inserted into the gap, and the other edge of the reed is tightly attached to the end face of the inner side of the outer ring; the lining is provided with a flange which outward extends in the radial direction; the end face of the outer side of the outer ring contacts the end face of a flange. Because the gap is remained between the outer ring and the lining of the bearing, and the automatic-aligning reed is provided, in the process of rotation, the rotation center of a clutch shaft and the rotation center of a bearing steel ball are automatically dressed to be concentric so that the friction between an inner hole of the lining and the clutch is avoided and the service life of the bearing is extended.

Description

Vehicle clutch disengaging bearing

Technical field

The utility model relates to automobile component, specifically a kind of bearing that is exclusively used on the heavy automobile clutch.

Background technique

The automobile release bearing is mainly used in the heavy-duty car motor, and clutch is connected with gearbox I axle.Existing clutch release bearing is usually by inner ring 1, outer ring 3, and the steel ball 4 that is positioned between inside and outside circle forms, and outer ring 3 is installed on the lining 8 again.There is following point in actual use in this bearing: because the rotating center of the rotating center of clutch cover and plate assembly and bearing is in making installation process, always produce deviation, during use, when being subjected to thrust, bearing presses to clutch lever (or separation refers to), when driving the bearing inner race rotation, this deviation can make and produce the disalignment rotation between bearing and clutch cover and plate assembly, thereby generation torsion, cause bearing heating, temperature raises, cause bearing to burn, lining comes off, and influences the working life of bearing.

Though the self-aligning clutch bearing of GB JB/T5312-2001 has solved the aligning problem, but its reed is installed on the left side of outer ring 3, for the connectivity problem that solves lining and outer ring need be provided with outer cover, the diameter that adds Large lining 8 and outer ring 3 connection parts, and adopt the press machine riveting to connect, therefore, technology more complicated, cost of production are than higher, and, in the clutch assembly of some vehicle, can't install because boundary dimension increases.

The model utility content

The purpose of this utility model is to design a kind of vehicle clutch disengaging bearing, between the outer ring of this bearing and lining, leave the gap, and be provided with the reed that is used for self-aligning, thereby in rotation process, but the rotating center of automatic dressing clutch cover and plate assembly and the rotating center of bearing, make both coaxial rotations, thereby avoided having prolonged the working life of bearing because of producing the problems such as bearing heating that torsion causes; Simultaneously, need not strengthen the boundary dimension of former bearing again, thereby, simplified manufacturing and installation process, reduced cost.

According to design proposal provided by the utility model, between L-shaped inner ring of section and outer ring, steel ball is arranged, inside and outside circle sky respectively is enclosed within outside the lining, between outer ring and lining, leave the gap, insert in the gap on one side of the reed that section is L-shaped, another side is close on the inner side end of outer ring, and the flange that extends radially outward is set on lining, and the outside end face of outer ring contacts with the end face of flange.

One side of being close to the outer ring interior edge face on reed is provided with to the outstanding projection of the direction of interior edge face, forms fulcrum.Position corresponding to reed on lining is provided with draw-in groove, and reed utilizes jump ring to be stuck in the draw-in groove.Fork slot is set on lining.Ask the retainer that is provided for stationary balls at inside and outside circle, seal ring is set in the left side of bearing.

The utility model has the advantages that: after being arranged at reed between lining and outer ring, just outer cover need not being set in the outside, outer ring of bearing, thereby just having reduced the external diameter of whole bearing, make simultaneously to install to be simplified, reduce cost with manufacturing.Between the outer ring of bearing and lining, leave the gap, and be provided with the reed that is used for self-aligning, thereby in rotation process, but the rotating center of automatic dressing clutch cover and plate assembly and the rotating center of bearing, make both concentric, thereby avoided the friction between lining endoporus and clutch cover and plate assembly, prolonged the working life of bearing

Description of drawings

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

Embodiment

As shown in the figure: between L-shaped inner ring 1 of section and outer ring 3, steel ball 4 is arranged, inside and

outside circle

1,3 sky respectively is enclosed within outside the lining 8, in the

outer ring

3 and 8 of linings leave gap 9, also leave enough spaces at

inner ring

1 and 8 of linings, during installation, outer ring 3 can contact with the end face of lining 8, inner ring 1 is adjacent with clutch lever, shift fork in embedding fork slot 13 is turned left lining 8 when stirring, flange 12 on the lining 8 just promotes outer ring 3, drive whole bearing and move to left, the inner ring end face is pressed to clutch lever (or finger), makes clutch be in separated state; Otherwise then be in the state that closes.

Insert in the gap 9 on one side of the reed 7 that section is L-shaped, and another side is close on the inner side end of outer ring 3, and the flange 12 that extends radially outward is set on lining 8, and the outside end face of outer ring 3 contacts with the end face of flange 12.One side of being close to outer ring 3 interior edge faces on reed 7 is provided with to the outstanding projection of the direction of interior edge face, forms fulcrum 11.When the inner ring end face contacts rotation with clutch lever, if the rotating center of bearing and the rotating center disalignment of clutch cover and plate assembly, then will inevitably produce torsion, compressing reed 7, under the elastic reaction of reed 7, the rotating center of bearing overlaps with the rotating center of clutch cover and plate assembly automatically, thereby avoided producing torsion because of both disalignment rotations, make bearing heating, temperature raises, and causes the problem of damage of bearings.

Position corresponding to reed 7 on lining 8 is provided with draw-in groove 10, and reed 7 utilizes jump ring 6 to be stuck in the draw-in groove 10, reed 7 is fixed on the lining 8, and produces certain axial force, and its right end face of outer ring 3 and the end face of flange of lining 8 are compressed.Fork slot 13 is set, so that shift fork is stirred lining 8 on lining 8.At 1,3 retainers 5 that are provided for stationary balls 4 of inside and outside circle, with

locking ball

4,3 left side is provided with seal ring 2 in the outer ring, in order to avoid dust etc. enter in the bearing.
