ある。The present invention has been made for the purpose of providing a clutch release bearing assembly that can eliminate the drawbacks of the above-mentioned conventional examples. That is, the present invention has been made for the purpose of reducing the weight of a bearing assembly and simplifying assembly, and the gist thereof is that the bearing holding means is made of a synthetic resin material with high lubricity. The structure includes a base made of a plastic material, and an operating part made of a highly rigid synthetic resin material.
以下、本発明の夾施例を示す図面に基づき更に詳述する
。DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, further details of the present invention will be explained based on drawings showing embodiments of the present invention.

向に移動可能とされている。In FIG. 1, the base or sleeve 2 is made of 6-6 nylon, which is a type of synthetic resin, and has a cylindrical shape. An annular protrusion 2a having a trapezoidal cross section is formed on the outer circumferential surface of the sleeve 2 at an intermediate portion in the longitudinal direction. This sleeve 2 is movable in the axial direction on a kite member 4 fixed to the transmission device.

層部１６においてスリーブ２と一体化されている。An operating section, ie, a carrier 6, is fitted and fixed on the outside of the sleeve 2, and the two constitute a bearing holding means. The carrier 6 is formed by adding 20 to 50% by weight of glass fiber to the above-mentioned 6-6 nylon. It consists of an extension part 6b. An annular space with a rectangular cross section is formed in one corner of the main body portion 6a, and a ring-shaped plastically deformable member 8 having a rectangular cross section is mounted within this annular space. An anvil 14 made of a metal plate is still buried in the other side of the main body 6a.
The roughness and abrasion resistance of this part are improved. This is because the fork member (not shown) comes into contact with this side surface during operation. The carrier 6 is integrated with the sleeve 2 at the weld layer portion 16 by ultrasonically welding the inner circumferential surface of the extension portion 6b to the outer circumferential surface of the sleeve 2.

周面に嵌合されている。A clutch release bearing 20 is mounted and held on the carrier 6 by a bearing case 12. Bearing case 12
is made of a metal plate, and consists of a large diameter cylinder 112a, a small diameter cylinder part 12b, and a connecting part 12C that connects the two,
The large diameter cylindrical portion 12a is fitted onto the outer peripheral surface of the outer ring 22 of the bearing 20, and the small diameter cylindrical portion 12b is fitted onto the inner peripheral surface of the plastically deformable member 8.

The bearing case 12 and the plastically deformable member 8 are held in the carrier 6 by engaging with a portion of the cylindrical portion 2C that is close to the cylindrical portion 1'2b. A gap 10 necessary for alignment is left between the cylindrical portion 12b of the bearing case and the sleeve 2.

The inner ring 26 is arranged with a certain amount of clearance 28 remaining between it and the outer circumferential surface of the sleeve 2, and is provided with a contact portion 26a that comes into contact with the diaphragm spring 30 on the minus side.

軸受２０を圧入嵌合し、端部をかしめつける。Next, the assembly of the bearing assembly having the above-mentioned structure will be explained. The plastic deformation member 8 is attached to the carrier 6, and the bearing case 12 is attached to this, and the sleeve 2 is assembled.
1 from the right direction in FIG. 1, and the sleeve 2 and carrier 6 are ultrasonically welded. Thereafter, the bearing 20 is press-fitted into the bearing case 12, and the ends are caulked.

性変形して、軸受２０をその位置に保持する。Next, the operation of this embodiment will be explained. When the fork member comes into contact with the anvil 14 and applies an axial thrust force to the carrier 6, the sleeve 2, the gear rear 6 and the bearing 20
moves integrally on the kite member 4. As a result, the contact portion 26a of the inner ring contacts the diaphragm spring 30 to release the clutch, and the inner ring 26 rotates with the diaphragm spring 30. At that time, diaphragm spring 30
If there is an eccentricity between the rotation center line of the bearing 20 and that of the bearing 20,
An alignment force acts on the bearing 20, and this alignment force plastically deforms the plastically deformable member 8 via the bearing case 12, causing the bearing 2
0 is aligned. The plastically deformable member 8 deforms plastically all at once (or gradually) to hold the bearing 20 in that position.

行なえて、製造コストが低減されるのである。In this embodiment, as described above, the sleeve 2 and the carrier 6 of the bearing holding means are made of different synthetic resin materials, so the sleeve 2Fi is made of 6-6 nylon, for example, with emphasis on lubricity. This makes it possible to eliminate the need for lubricants. On the other hand, Carrier 6 emphasizes rigidity, and uses, for example, 6-6 nylon and glass fiber at a weight ratio of 2.
It was made by mixing 0 to 50%. As a result, the weight is significantly reduced compared to the conventional one, and the separate sleeve 2 and carrier 6 can be easily assembled with the bearing 20, thereby reducing manufacturing costs.

状部材３４をスリーブ２に溶着しても良い。As shown in FIG. 3, the extension 6b is removed from the carrier 6 and an annular recess 2b is formed in its place.
The anvil 14 can be positioned by using this annular recess 6c, or by fitting a member 32 separate from the sleeve 2 into the annular groove 2d of the sleeve 2, as shown in FIG. 2a, and an annular member 34 separate from the carrier 6 may be welded to the sleeve 2.
なお、キャリヤ６のうち軸受ケース１２に接触する突部

触するとと＼なって望ましい。Note that it is preferable that the protrusion 6f (FIG. 4) of the carrier 6 that contacts the bearing case 12 be formed of a metal member so that the two can come into metal contact.

ている。Furthermore, as shown in FIG. 5, a metal positioning member 36 may be used instead of the annular protrusion 2a. This positioning member 36 has a flange portion 36a facing radially inward and locked to the step portion of the sleeve 20, a flange portion 36b facing outward and located on the side of the bearing case 12, and a cylindrical shape connecting the two. The connecting portion 36c provides a more stable holding action than the annular protrusion 2a of the previous embodiment.
