Definitions

• the present invention mainly relates to an improvement of a cladding disk suitable for a clutch of a high-speed car such as a passenger car.
• Figure 5 shows a typical spline hub shape. 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.
• 3 6 is internal teeth With a plan.
• the present invention improves the shape of the window hole of a spline knob, which is a heavy part of the assembly, thereby improving the amount of inertia.
• the purpose is to reduce the amount of inertia
• an integrated side plate is arranged on both sides of a flange portion on an outer periphery of a spline hub, and a friction fencing is attached to an outer periphery of one side plate, and a flange is provided.
• a clutch disk in which a torsion spring or a torsion rubber is fitted to window holes provided at a plurality of locations facing the flange and the side plate. Fit the edges of the flanged window holes on the outer peripheral side of the flanges to both ends to lock the spring ends.
• This is a crack disk characterized by being resected excluding a part of the top.
• FIG. 1 is a partial front view of a spline hub to which the present invention is applied
• FIG. 2 is an operation explanatory view
• FIG. 3 is a view of a spline hub having the spline hub of FIG. Partial cutaway front view of a latch disk
• Fig. 4 corresponds to Fig. 3
• section IV-IV Fig. 5
• Fig. 6 correspond to Fig. 1, showing the conventional structure BEST MODE FOR CARRYING OUT THE INVENTION
• the outer peripheral portion of the square window 3 is provided with a gap 8 (edge cutout) between both end stopper projections 7, 7 for engaging the spring ends at both ends. Open to the outside.
• the cutout 8 is formed by removing the middle part of the rim 5 in FIG.
• the projections 7, 7 can be formed by leaving both ends of the conventional edge 35 (FIG. 5), and the portion of the projection 7 facing the inside of the window hole 3 has a toe.
• the convex smooth surface 7a facing the spring 4 is formed.
• Spline hub 1 shown in Fig. 1 is incorporated in Figs. 3 and 4, and 10 and 11 in Fig. 4 are side blades (cladders). Both the plate 10 and the plate 11 are integrated by the stop pin 12 in the print plate and the retaining plate.
• the side plate 10 has a friction face 14 via a cushioning plate 13 on the outer periphery.
• Flange part 2 and side plate 10 Friction ⁇ and sociator 15 are arranged between them.
• force on flange 2 side, Flection Fushion 16 and FJ Foxy Plate 17 and Confusion 18 are arranged, and Flange 2
• the hysteresis characteristic is obtained by the friction between the two halves 115 and 16.
• the above-mentioned discussion screen is provided.
• the torsion spring is provided with torsional rigidity by the torsion springs 4 and 4a.
• some of the transition springs are attached to the end faces 3a on both sides in the rotation direction of the window hole 3 of the flange 2 as shown in Fig. 3.
• the side plate is supported on the window holes 21 and 22 (Fig. 4) side of the side plate so as to leave a gap 24 between itself and the window hole end surface 3b.
• both ends of all torsion springs May be supported by the hub flange or the side edge of the side plate.
• Rotational force is applied to the hub flange 2 from the outer peripheral friction fing 14 side, and both side plates 10 and 11 (Fig. 4) are twisted.
• the torsion spring 4 is hooked on the side plate side windows 21 and 22 and compressed in the direction of arrow R.
• the number of rotations rises with no or little relative twist between the side plates 10 and 11 and the hub flange portion 2, and the torque increases.
• the centrifugal force acting on the spring 4 increases, the spring 4 tries to protrude outward in the radial direction. Since both ends of the ring are supported by the rounded surface 7a of the stopper projection 7, further outward protrusion in the radial direction is prevented.
• the weight of the outer peripheral portion of the heavy component spline hub is reduced, and the amount of inertia is reduced. This makes it easier to engage the gear during gear change. This will extend the life of the synchro.
• the stopper projection 7 for positioning the torsion spring is provided at the end of the square window, centrifugal force acting on the torsion spring is provided. Can be received by the projection 7, there is no longer any element that hinders the operation of the torsion spring, and the torsional characteristics during rotation are stabilized.
• the present invention can be applied to various kinds of automatic clutches including a private automobile.
