[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, a friction disc mechanism for a traction machine includes a support plate 1. The support plate 1 has a through-type mounting groove inside. A friction disc 2 is fixedly mounted inside the mounting groove and to a rotating shaft via a spline 5. A brake 6 is fixedly mounted on the rear surface of the support plate 1 and is mounted to the rotating shaft.

[0025] Springs 7 are provided above and below the friction disc 2 and the brake 6, and the springs 7 are fixedly connected to the friction disc 2. During operation, the springs 7 placed below the friction disc 2 prevent the friction disc 2 from sticking to the end face during operation. Compared with traditional traction machines, there is no rubbing noise, which increases customer comfort and reduces the wear of the friction disc 2, thus extending the life of the friction disc 2.

[0026] The spline 5 has multiple evenly distributed through holes 11 inside, and a screw 3 passes through the through hole 11. A nut 4 is threaded to one side of the outer surface of the screw 3. The screw 3 is installed with the friction disk 2 through a limiting component. During operation, a flat-head screw 3 is placed on the spline 5, and the distance that the friction disk 2 can move is controlled by the nut 4. The limiting component limits the screw 3, so that the nut 4 can be rotated to make the movement distance of the friction disk 2 adjustable.

[0027] One end of the spring 7 is in contact with one side of the brake 6; during operation, the spring 7 is not connected to the brake 6, and the spring 7 can rotate together with the friction disc 2.

[0028] The outer surface of the nut 4 is in contact with the outer surface of the spline 5; during operation, the nut 4 can rotate and can be separated from the surface of the spline 5.

[0029] The limiting component includes a connecting rod 8, which is installed on the friction disc 2 via an installation component. A through-type limiting groove 9 is provided at the bottom of the connecting rod 8, and a limiting rod 10 is slidably connected inside the limiting groove 9. One end of the limiting rod 10 is fixedly connected to the outer surface of the screw 3. During operation, the limiting groove 9 at the bottom of the connecting rod 8, installed by the installation component, limits the limiting rod 10, and the limiting rod 10 is fixedly connected to the screw 3. Therefore, the connecting rod 8, the limiting groove 9, and the limiting rod 10 limit the screw 3. Furthermore, rotating the nut 4 adjusts the distance the friction disc 2 can move, and this distance is the distance between the friction disc 2 and the limiting rod 10. Thus, by positioning the nut 4 at different positions on the outer surface of the screw 3, the distance between the friction disc 2 and the limiting rod 10 can be adjusted.

[0030] One end of the connecting rod 8 is in contact with one side of the friction disc 2. During operation, the connecting rod 8 can be disassembled through the mounting assembly, which makes it easy to disassemble, replace and repair the connecting rod 8, the limiting rod 10, the screw 3 and the nut 4.

[0031] Example 2

[0032] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the mounting component includes a threaded hole 12 on one side of the friction disk 2, and a threaded rod 13 is threadedly connected inside the threaded hole 12. The threaded rod 13 is fixedly connected to the connecting rod 8. During operation, the connecting rod 8 and the friction disk 2 are fixedly installed through the threaded connection between the threaded rod 13 and the threaded hole 12, which also facilitates the disassembly of the connecting rod 8.
