Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1, the present embodiment provides a clutch facing, which includes a steel disc 1, and a plurality of friction plates 2 disposed on a surface wall of the steel disc 1 at intervals along a circumferential direction of the steel disc 1, such that the friction plates 2 are independent from each other and are independent parts, such that when one of the friction plates 2 is seriously worn, only the friction plate 2 needs to be replaced, and it is not necessary to replace all the friction plates 2.

The friction plate 2 is installed on the steel disc 1 through a connecting member, in this embodiment, as shown in fig. 2, the connecting member may adopt a countersunk screw 5, and the existing countersunk screw 5 generally includes a screw rod portion with threads and a nut portion disposed on the screw rod portion, which is not described herein again.

The friction plate 2 is provided with a through hole 21 for the screw rod part of the countersunk head screw 5 to pass through; the radius of the through hole 21 is smaller than the radius of the cap portion, thereby ensuring that the cap portion of the countersunk-head screw 5 does not penetrate into the through hole 21.

The outer wall of the friction plate 2 is provided with a containing hole 22 which is coaxially arranged with the through hole 21 and is communicated with the through hole for containing the cap part of the countersunk head screw 5; the surface wall of the steel plate 1 is provided with a threaded hole 11 corresponding to the through hole 21 for the screw rod part of the countersunk head screw 5 to be in threaded connection.

With the above arrangement, as shown in fig. 3, when the friction plate 2 is installed, the friction plate 2 is first placed on the steel plate 1, so that the through hole 21 of the friction plate 2 is aligned with the threaded hole 11 of the steel plate 1; then, the shank part of the countersunk head screw 5 penetrates through the through hole 21 and extends into the threaded hole 11, then the countersunk head screw 5 is rotated to enable the countersunk head screw 5 to be screwed into the threaded hole 11, and finally the friction plate 2 is installed.

Similarly, when a friction plate 2 with serious abrasion needs to be replaced, the countersunk head screw 5 on the friction plate 2 is screwed off.

After friction disc 2 installed on steel disc 1, mainly rely on countersunk screw 5's effect to realize friction disc 2 fixed, but friction disc 2 is when using, can produce stress between the perforation 21 wall of friction disc 2 and the nail pole portion of countersunk screw 5, long-term the use causes friction disc 2 to the skew of one side easily, so the further improvement is done to this embodiment, and is concrete:

both sides of the friction plate 2 are respectively connected with a limiting strip 3 fixedly arranged on the steel disc 1. The two sides of the friction plate 2 are blocked by the limiting strips 3, so that the friction plate 2 is placed to be deviated to the two sides.

Spacing 3 keep away from rather than the friction disc 2 one side of butt be equipped with a plurality of along spacing 3 length direction interval distribution's heat dissipation gusset 4, wherein spacing 3, the heat dissipation gusset 4 of being connected with spacing 3 to and 1 three of steel disc are the integrated into one piece structure, are heat conduction steel structure.

So, the heat transfer that friction disc 2 work produced gives steel disc 1, and partly gives off by steel disc 1 self, and another part gives spacing 3 by steel disc 1 transmission, gives off for heat dissipation gusset 4 by spacing 3 transmission again, so in order to accelerate the radiating effect.

The design of the heat dissipation rib plate 4 firstly increases the heat dissipation area, and secondly, the heat dissipation rib plate 4 can play a role of a reinforcing rib and plays a role of reinforcing the limiting strip 3.

The steel disc 1 is provided with a mounting hole 12 for mounting the steel disc 1 at a position between the two adjacent limiting strips 3.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
