Abstract

Clutch disc, wherein side plates are provided on both sides of a flange portion of a spline hub with a friction facing attached to one of the side plates, torsion springs being fitted in the bores provided in a plurality of opposed sections of the flange portion and side plates, characterized in that the edge section of each of the bores which is on the side of the outer circumference of the flange portion is cut off with both end regions, which serve as spring end-engaging stopper portions, of the edge section left not cut off. According to the present invention, the quantity of inertia force of a clutch disc assembly becomes small. Accordingly, the speed change gear can be set in different positions easily, and the lifetime of the synchro-mesh clutch lengthens. The centrifugal force working on the torsion springs can be received at projections, so that factors preventing the operations of the torsion springs can be eliminated. This enables the torsion characteristics of the clutch disc during the rotation thereof to be stabilized.

That is, in the flange portion 32 formed integrally with the outer periphery of the cylindrical spline hub 31, square windows 33 are formed at a plurality of positions on the circumference. A torsion spring 34 described later is arranged in the rectangular window 33 in such a manner as to extend in the circumferential direction. Since the outer peripheral side of the flange portion of the square window 33 is closed by the edge 35, the centrifugal force of the torsion spring 34 is received by the edge 35. Although it can be stopped, since the flange 35 has an edge 35 on the outer periphery, the amount of inertia increases, making it difficult for the gear to enter and the synchro The aforementioned problems, such as shortening the service life, are inevitable. 3 6 is internal teeth With a plan.

It cannot be received by the edge part 42, but it can be received only by the side plates (classes, zochi plates and U-tining plates) described later. When the eleventh spring is extended outward by a sword, it rubs against the window hole of the side plate, and the torsional characteristic is lost during rotation. Since only the side plate is supported by the torsion spring, it is disadvantageous in terms of strength, such as breaking the window of the side plate.
