Description
(54) A CLU?YIH THRUST GUIDE ASSEMBLY (71) We, NADELLA, a French Corporate Body of 133-137 Boulevard National, 92505-Rueil Malmaison, France, do hereby declare this invention, for which we pray that a patent may be granted ro 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 clutch thrust guide assembly for guiding dutch thrust members and housing bearings.
Clutches are known to have a thrust bearing guided by a tubular member of which one portion is mounted in a support through which a clutch shaft passes. The support is often also designed to receive a seal to prevent leakage of lubricating oil from, for example, a gear box into the clutch. The support also has to house means to radially locate the shaft and-possibly retain the seal in the support against movement due to shaft vibrations. The necessity of hav-- ing to insert all these parts into the support can cause problems of space and arrangement such that a given support may be unable to accommodate all the parts.
Additionally, the many means needed to keep the different parts assembled, particularly the guide on the support, means that assembling and or centering the guide in relation to the shaft is often compromised.
It is an object of the present invention to provide a clutch thrust guide assembly made in such a way 'that several parts can be assembled and inserted into, and which can be correctly centred in relation to the support.
According to the present invelltion, a clutch - thrust guide assembly comprises a generally cylindrical sleeve part, designed to guide a clutch thrust member, joined to a support part to be mounted in a support and forming a housing for or the outer race a a rotary bearing for a shaft passed through the assembly.
The above and other features of the in vention are illustrated; by way of example, by the accompanying drawings, in which: Fig. 1 is a sectional view of a first embodiment of the invention, in position in a support and clutch; Thg. 2 is a sectional view of a second embodiment of the invention in position in a support; and
Figs. 3 and 4 are, respectively, similar views of two further embodiments of the invention.
Fig. d shows a first embodiment of the invention to be a clutch thrust guide assembly 1 having two parts. A generally cylindrical part 2 forming a guide for the thrust member 3 of a clutch 4. The thrust member may be a thrust ring or a thrust bearing and, in the example, is shown to be a thrust bearing actuated by a lever 6 to slide longitudinally of the guide part 2 to engage and disengage the clutch.
The second part of the assembly is a cylindrical support part 5, of larger diameter than the sleeve part 2, and, having at its end adjacent the sleeve part, an inturned radial flange 7. The support part 5 is shaped to be mounted in the bore 8 of a support 9 with a shaft 10 passing through the support bore 8 and the assembly 1. The shaft 10 could be the primary shaft of a gear box or could also be a shaft connecting a clutch to the input of a gear box.
The shaft 10 forms the inner lace for bearing needles or rollers 13 that are retained by a cage 14, the outer bearing race being a cup-shaped, pressed plate bushing 11 housed within the support part 5. Bushing 11 also acts as an end cap for the assembly. A washer 20 separates the open end of the bushing all from a sealing ring 15. Guide part 2, being of lesser diameter than support part 5, has, near its end adjacent the support part 5, an outurned radial shoulder 23 that has an axial, cylindrical extension 22 that butts against the open end of the and is the same diameter as the bushing 11. Radial flange 7 on the support part 5 overlies shoulder 23 on the guide part 2 to join sleeve part 2 to support part 5.
To minimise play of the bearing elements within the support portion, a bearing with radial play take-up may be employed to correct for out of tolerances of the bearing elements. A suitable bearing is described in our Patent No. 1,433,953 and Patent of
Addition No. 1,484,777.
It is also possible to correct for such out of tolerances by gauging the external surface 16 of the support part 5 with respect to the inner or race surtace of the busying 11 in such a way that the bushing-support -unit has a predetermined thickness. Our
Patent No. 1,351,217 discloses a sllitab!e gauging method. The support part of the guide corresponds to the unit described in this Patent and is composed of two concentric elements of which the internal element is a hardened sheet bushing and the external element is a tubular member clamped onto the bushing and when necessary having a greater thickness than the bushing to contribute to maintaining a desired shape for the bushing.
As the function of the guide assembly differs from that of the bearing bushing the sleeve can be made of any, preferably ductile, material. The guide part 2 can be suitably coated with, for example, metals such as copper or cadmium or synthetic materials such as TEFLON (Trade Mark) or RILSAN (Trade Mark).
Use of a separate support part 5 enables a pressed bushing to be employed and this means that the support material need not be a bearing material.
The embodiment shown by -Fig. 2 is similar to that of Fig. 1 except that the inturned radial flange 7 of support part 5 has an axial, cylindrical extension 25 to overlie and centre guide part 2. Also, guide part 2 ends with shoulder 23 as an outurned radial flange that is fixed, for example welded, to the inside of the inturned radial flange 7. This arrangement both protects the weld and centres the guide part
Fig. 3 shows another embodiment in which guide part 2 has an outurned radial flange 23. The bearing bushing 11 is extended to include an internal sealing ring 28 and a radially inturned flange 27 at the end of the bushing bears against the flanged end 23 of guide part 2. Flanges 27 and 23 are trapped within support part 5 by a radial flange 7 at the end of part 5 that is inturned to clamp guide part flange 23 to bushing flange 27.
In the embodiment shown by Fig. 4, the support part 5 also acts as the outer race for the bearing, the rolling members 13 of which are held by a cage 14. Guide part 2 has an outurned radial flange 23 welded to the outside of an inturned radial flange 7 at the adjacent end of the support part 5. Part 5 is shown to have another inturned radial flange 26 at its other end to contain the bearing members 13 and the cage 14 and an internal sealing ring 15 within the support part 5. In this em embodiment the support part material is a metal having the necessary characteristics, particularly with regard to hardness, to enable it to function as a bearing race. As before, the outer surface of the guide part 2 may be coated.
