Abstract

In order to secure any one of a number of friction pads 16 to a facing 13 of a driven plate 12 of a clutch disc, a rivet is arranged to extend through a hole in the plate 12 and a hole 17 in the facing 13 and is fixed on that side of the plate 12 remote from the facing 13. On the other side of the plate 12 (i.e. the same side as the facing 13) the rivet has a cupshaped head 15a into which the friction pad 16 is bonded so that the pad is flush with the surface of the facing 13. The facing 13 is organic, the pad 16 is cerametallic. <IMAGE>

Description

SPECIFICATION Clutch disc This invention relates to a clutch disc.
In order, in known clutch discs to complement wear resistibility of the disc's organic facing, various facings of the so called combination type, which consist of organic facings in combination with cerametallic facings comprising sintered alloy having high wear resistibility, are commonly utilized.
An object of the present invention is, with clutch discs employing the above combination type facing, to improve the fastening strength of the cerametallic facing. Another object of the invention is to improve the anti-bursting strength of the organic facing. Yet a further object of the invention is to reduce the quantity of clutch disc parts and therefore to ease the work involved in assembling the clutch disc.
In order to achieve the above objects, the present invention provides a clutch disc, in which an organic facing is formed into an integral annular piece, a rivet head for fastening the organic facing to a driven plate is cupshaped and has a specific area, and a cerametallic facing is held in the cupshaped head.
The invention will be described further, by way of example, with reference to the accompanying drawings in which: Fig. 1 is a sectional elevation on the line I-I of Fiy. 2 of the upper half of the preferred clutch disc of the invention, and Fig. 2 is a front view of the clutch disc of Fig. 1.
Referring to Fig. 1 the preferred clutch disc according to this invention, comprises a spline hub 1 of an output side of the clutch disc, a flange 2 formed on the hub 1, side plates 3 8 4 arranged on both sides of the flange 2, a coil spring 5 arranged in a window hole 7 of the flange 2 and window holes 8 8 9 in the side plates 3 8 4. A stud pin 6 interconnects both of the side plates 3 8 4 and fits in a hole 2a of the flange 2 so that there is play of the pin 6 in the circumferential direction of the flange 2. A friction member 10 is arranged between both sides of the flange 2 and the side plates 3 a 4. With a conventional clutch disc, torque is transmitted from the side plates 3 s 4 through the coil spring 5 to the flange 2 and the hub 1 when rotational torque is small.
However, the stud pin 6 contacts the periphery of the hole 2a and torque is transmitted through the stud pin 6 to the flange 2 and the hub 1 when the rotational torque is large and causes a certain angle of distortion of the side plates 3 8 4 in relation to the flange 2.
An annular driven plate 12 is fixed to an outer peripheral edge of the side plate 3 by means of rivets 11, and a respective annular organic facing 13, 13' and a respective cerametallic facing (cerametallic pad) 1 6 are fixed to both sides of the driven plate 12 by means of rivets 1 5. Since the methods of fastening the left organic facing 1 3 and that of the right organic facing 13' are the same, only the method of fastening the left organic facing 1 3 and the cerametallic facing 1 6 will be described hereunder.
A fastening hole 1 7 having a shoulder 1 /a Is formed in the left organic facing 13. A head 1 5a of each rivet 1 5 is formed into a cup shape, and an outward flange 1 Sc is formed on the left edge of the cupshaped head 1 spa. The rivet 15, which is fitted in the hole 1 7 from the left side thereof retains the shoulder 1 7a by means of its outwardly projecting flange 1 sic, and a portion cf the rivet 1 5 projecting into the right side of the driven plate 12 is staked.A hole 1 8 is formed in organic flange facing 13', in order to incorporate the staked portion of the rivet 1 5 for fastening the left organic facing 1 3. The cerametallic facing 1 6 is fitted in the cupshaped head 1 5a of the rivet 15 and is bonded to the cupshaped head 1 spa by means of a bonding agent. The left part (friction surface) of the cerametallic facing 1 6 protrudes leftward from the cupshaped head 1 5a.The cerametallic facing 16 may be bonded to the cupshaped head 1 5a prior to the fixing of the facing 13 to the driven plate 12, or may be bonded to the cupshaped head 1 spa after the organic facing 1 3 has been fixed to the driven plate 12 by staking the rivet 1 5.
Referring now to Fig. 2, it is clearly shown therein that the organic facing 13 is an integral annular piece, and the geometry and arrangement pattern of the cerametallic facing 1 6 is illustrated as viewed in the direction of the arrow II of Fig. 1.
There are four cerametallic facings 16 arranged equal spacings from one another in the circumferential direction in case of the clutch disc.
The arrangement of the cerametallic facings 16, as viewed in the direction of the arrow II of Fig. 1, is circular. The hole 18 for a rivet 15', which fastens the organic facing 1 3' at the rear of the driven plate 12, is formed between the fastening holes 17.
As mentioned above, the foilowing advantages are provided by the clutch disc according to this invention: (1) Since the head 1 5a of the rivet 1 5 is formed into the cupshape and the cerametallic facing 1 6 is held in the cupshaped head 1 spa, it becomes possible te hold securely the cerametallic facing 1 6 and there is little possibility of the cerametallic facing 16 falling off the driven plate 12; (2) Since the rivet 1 5 serves as a holing member for the cerametallic facing 1 6 and as a fastening member for the organic facing 13, it becomes possible to reduce considerably the quantity of parts required for fastening the facing 13 to the plate 12 and therefore simultaneously to ease the work in assembling the clutch disc;; (3) The rivet 1 5 and the cerametallic facing 1 6 are arranged in the same fastening hole 1 7 on the organic facing 13, so that it becomes unnecessary to provide a hole for the rivet 1 5 and a hole for the cerametallic facing 1 6 separately. Therefore, the anti-bursting strength of the organic facing 1 3 can be remarkably improved due to a smaller quantity of holes, which must be formed on the organic facing 13, in combination with the integral annular form of the organic facing 13; and (4) It goes without saying that wear resistibility can be improved because the organic facing 13 is combined with the cerametallic facing 1 6.
Although the cerametallic facing 1 6 is bonded to the cupshaped head 1 5a, other fastening methods may be employed. Various fastening methods, such as utilizing the shrink fit method or utilizing a stopper projection which permits the cerametallic facing 1 6 only to be inserted, may be adopted.
