Description

(54) COMBINATION OF A CLUTCH RELEASE BEARING ASSEMBLY AND A DIAPHRAGM SPRING (71) We, SKF KUGELLAGERFABRIKEN GESELLSCHAFT MIT BESCHRANKTER HAFTUNG, a German Body Corporate, of Ernst Sachs-Strasse 2-8, 8720 Schweinfurt 2, German Federal Republic, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement - This invention relates to a combination of a clutch release bearing assembly located in the bore of a clutch diaphragm spring.
According to the invention a combination of a clutch release bearing assembly located in the bore of a clutch diaphragm spring comprises a rolling bearing having an inner race ring and an outer race ring, and a retaining ring axially secured to one of the race rings and having an annular groove receiving the free ends of the race ends of the fingers of the clutch diaphragm spring, the annular groove having radially extending annular surfaces for contact by the fingers, which surfaces are provided solely by the retaining ring.
The retaining ring may be secured to an axially extending annular projection of the outer race ring.
The retaining ring may be secured to a radially outwardly extending annular flange of the inner race ring.
The retaining ring in axial section may have an axially extending portion, a limb extending radially outwardly from one end of the axially extending portion and a limb extending radially inwardly from the other end of the axially extending portion, and an annular bead on the axially extending portion which, with the radially outwardly extending limb forms the annular groove.
The retaining ring may be secured onto the radially outer surface of the outer race ring.
The retaining ring may abut a radially outwardly extending annular flange of the outer race ring and may be secured to the outer race ring by means of a connecting ring.
Embodiments of the invention will now be described by way of example, reference being made to the accompanying drawings, of which: Figure 1 is one half of an axial section of a clutch release bearing assembly with part of a diaphragm spring shown in chain dot; Figure 2 is one half of an axial section of a different clutch release bearing assembly; and Figure 3 is one half of an axial section of another clutch release bearing assembly.
Referring to Figure 1 the clutch release bearing assembly comprises a sleeve 8 and a rolling bearing arranged around the sleeve 8. Th bearing comprises an inner race ring 1, an outer race ring 2, a cage 3 and an annular series of rolling elements 4 arranged to roll on the raceways of the race rings 1 and 2.
The sleeve 8 has a separately formed radially outwardly extending annular flange 7 against which abuts a radially outwardly extending annular flange 6 of the inner race ring 1. Relative rotation between sleeve 8 and inner race ring 1 is prevented by co-operating recesses and projections, although a limited amount of relative radial displacement is permitted.
A sealing ring 5 is attached to the radially outer end of the outer race ring 2 nearest to the sleeve flange 7 and extends radially inwardly to the inner race ring 1.
Outer race ring 2 has, at the radially inner end furthest from the sleeve flange 7, an axially extending annular projection 9. A retaining ring 10, circumferentially surrounding the bearing, is attached to annular projection 9 and is axially located by means of radially outwardly extending projections 17 on projection 9.
Retaining ring 10 comprises in axial section an axially extending portion 13, a limb 12 extending radially outwardly from one end of portion 13 and a limb 11 extending radially inwardly from the other end of the portion, which limb 11 is attached to projection 9 of the outer race ring 2. Axially extending portion 13 has an annular bead 14, which together with limb 12 forms annular groove 15, in which groove 15 are engaged the free ends of the fingers 16 of a clutch diaphragm spring.
Referring to Figure 2, the sleeve 8 has an integral outwardly extending annular flange 7, and relative rotation is prevented between the sleeve 8 and outer race ring 2 by means of cooperating projections and recesses on the sleeve flange 7 and a radially inwardly directed flange of the outer race ring 2.
Inner race ring 1 has a radially outwardly extending annular flange 18 and limb 11 of retaining ring 10 abuts the face of flange 18 furthest from the sleeve flange 7. Co-operating projections and recesses on limb 11 and flange 18 prevent any relative rotation between inner race ring 1 and retaining ring 10. Retaining ring 10 is axially located with respect to inner race ring 1 by means of projection 19 extending radially inwardly from the inner surface of axially extending portion 13 on the side of flange 18 nearest to sleeve flange 7. Otherwise the construction offretaining ring 10 is substantially the same as for Figure 1.
Referring to Figure 3, sleeve 8 has an integral radially outwardly extending annular flange 7, inner race ring 1 has a radially outwardly extending flange which abuts flange 7, and relative rotation between sleeve 8 and ring 1 is prevented by co-operating projections and recesses.
Retaining ring 10 is secured onto the outer surface 20 of outer race ring 2 and comprises in axial section two radially outwardly extending limbs 12 and 21 forming between them annular groove 15 for the clutch diaphragm spring. Limb 12 of the retaining ring 10 abuts a radially outwardly extending annular flange 22 of the outer race ring 2 at the end nearest to sleeve flange 7. Retaining ring 10 is secured to outer race ring 2 by a connecting ring 23 which has a portion 24 extending over the radially outer end of limb 12 and extends radially inwardly past flanges 22 and 7. A resilient sealing ring 25 is disposed between flange 22 and connecting ring 23.
All the embodiments described have sheet metal race rings which are cheaper and lighter than solid race rings, but the invention is not limited to sheet metal race rings.
Although each of the embodiments described has a sleeve, the invention is not restricted to having a sleeve. The sleeve can be omitted and the elements actuating the clutch can engage directly one of the race rings of the bearing.
It will be seen that the annular groove 15 in Figures 1 to 3 has radially extending annular surfaces for contact by the fingers 16, which surfaces are provided solely by the retaining ring.
WHAT WE CLAIM IS: 1. A combination of a clutch release bearing assembly located in the bore of a clutch diaphragm spring, the assembly comprising a rolling bearing having an inner race ring and an outer race ring, and a retaining ring axially secured to one of the race rings and having an annular groove receiving the free ends of the fingers of the clutch diagraphm spring, the annular groove having radially extending annular surfaces for contact by the fingers, which surfaces are provided solely by the retaining ring.
2. A combination as claimed in claim 1 wherein the retaining ring is secured to an axially extending annular projection of the outer race ring.
3. A combination as claimed in claim 1 wherein the retaining ring is secured to a radially outwardly extending annular flange of the inner race ring.
