Definitions
- the invention relates to a clutch release bearing, comprising an operating element intended to be subjected to the action of a control member, and an actuating element in axial abutment against the operating element and which, under the action of said operating element, acts on the disengaging device of a clutch mechanism.
- the publication FR-A-2607885 describes a declutching stop in which the operating element and the actuating element are secured by means of an elastic washer with axial action, which has a service position in which the washer exerts a retaining force on both elements of the stop.
- the operating element is actuated by way of nonlimiting example by a fork and displaces an actuating element, such as a bearing.
- bearing support or “support” means the axially movable operating element, under the action of a control fork.
- Another unresolved problem on the clutch release bearings lies in the fact that the axial thrust force of the assembly washer mounting tool is exerted in an area of lower resistance of the washer.
- the present invention therefore aims more particularly to improve the assembly of the bearing with its support by the use of an elastic washer with axial bearing action, mounted in compression between said bearing and support.
- the washer has a first series of elastic retaining claws, mounted in axial support on a circular rib of the support, and a second series of actuating claws directed in the opposite direction to the direction of assembly of the washer, and on which the ends of the prongs of the first series are respectively arranged along a first circumference whose diameter is less than that of the circumference passing through the top of the rib, while the ends of the prongs of the second series are arranged along a circumference whose diameter is greater than that of the circumference passing through the top of the rib.
- the stop thus produced, authorizes the pressing of a pushing tool on the actuating claws, the axial displacement of which allows the retaining claws to catch on the circular rib of the support.
- the stop in accordance with the invention allows the use of a mounting tool of reduced size, which ensures rapid axial immobihsation of the bearing on its support.
- the tool rests on the different actuating claws of the washer and abuts on the rib, circular support, which allows to exert a significant effort without risk of damage to the washer.
- the circular fold line of the retaining and actuating claws extends along a circumference whose diameter is substantially equal to the diameter of the circumference passing through the top of the rib. This constructive measure ensures the bending of the actuating claws during their relative displacement relative to the retaining claws, in the plane of the rib, and the positioning of said actuating claws parallel to the axis of the stop.
- This constructive measure also improves the support of the tooling on the actuating claws and ensures better transmission of the thrust force by reducing the risks of deterioration of said claws.
- FIG. 1 is a half view, in axial section of an assembled stop, according to the invention.
- FIG. 2 is a half view, in axial section, of a first variant of reahsation of the stop.
- FIG. 3 is a half view, in axial section, of a second variant of
- FIG. 4 is a perspective representation of the assembly washer of the thrust bearing on its support.
- FIGs 5, 6, 7 are half-views in axial section of the stop shown in Figures 1, 2, 3, during the assembly phase of the thrust bearing on its support.
- the clutch release bearing according to the invention has the following main functional elements:
- a bearing support 10 which is intended to be subjected to the action of an operating member, constituted by way of nonlimiting example by a control fork, not shown.
- a thrust bearing 11 directly in abutment, for example against a radial flange 12 of the support 10.
- the bearing 11 acts on the declutching device, constituted by way of nonlimiting example, by the ends of the fingers of a diaphragm which is part of a clutch mechanism, also not shown.
- the support 10 is constituted, according to a known configuration, by a sleeve 13 whose end carries the annular radial flange 12.
- the sleeve 13 is of cylindrical configuration and carries on its outer cylindrical surface, a circular rib 14, for locking the assembly washer 15 of said support 10 and bearing 11.
- the bearing 11 has, in a manner known per se, an outer ring 21 and an inner ring 22, which carry the raceways of the rolling bodies 23, mounted in a cage 24.
- a seal 25 is integral with a frame made of sheet 26, crimped onto the outer ring 21.
- the outer ring 21 has a dropped edge 27, directed radially towards the axis of rotation of the bearing and mounted in abutment on the flange 12 of the support 10.
- the ring 22 also carries in known manner, a fallen edge 28, directed radially towards the axis of rotation of the bearing and adapted to act on the diaphragm of the clutch mechanism.
- FIG. 4 shows the assembly washer 15.
- the latter has a radial support edge 29, intended to cooperate with the internal face "i" of the fallen edge 27 of the outer ring 21, facing the inner ring 22.
- the assembly washer 15 also has a termination constituted by a set of axial claws 30 distributed at the end opposite to that of the radial bearing edge 29.
- a first series of elastic retaining claws 30r is intended to come to bear axially on the circular rib 14 of the support 10.
- a second series of actuating claws 30a is intended to form the support of a mounting tool 40 as shown in FIGS. 5 to
- the ends of the claws 3 Or of the first series are elastic and exert a bending force in the direction of the foot of the rib 14.
- the ends of the claws 30r are moreover arranged along a first circumference D1 whose diameter is less than that of the circumference passing through the top of the rib 14.
- the ends of the claws 30a longitudinally alternating with the claws 30r along the periphery of the washer, extend axially and along a second circumference D2 whose diameter is greater than that of the circumference passing through the top of the rib 14.
- the claws 30a and 3 Or are directed in the opposite direction to the mounting direction of the washer and are of unequal lengths.
- the difference in claw length 30a and 3 Or is at least equal to the thickness of the rib 14 as shown in FIGS. 5 to 7.
- This arrangement favors the contact of the washer 15 with the mounting tool 40 and the temporary immobilization of the bearing 10 during the movement of the support 11.
- the end of the support 10 and the rib 14 also move and radially deform all of the retaining claws 30r.
- the claws 30r have a circular line D3 of phage together with the claws 30a and the diameter of this line of phage is substantially equal to the diameter of the circumference passing through the top of the rib 14.
- Such a configuration promotes the expansion of the claws of the washer during mounting of the bearing on its support.
- Figure 2 shows that the washer 15 can be immobilized as a result of the prior pressing on the washer, the end of the inner ring 22 of the bearing.
- FIG. 3 shows that the washer 15 can be immobilized as a result of the prior pressing on the washer of the cage 24 of the bearing 11.
