Description

Technical Field

[0001] The utility model relates to a clutch friction disc, in particular to a split friction disc for a clutch. Background Art

[0002] The friction disc relies on friction to achieve the drive or brake of the rotating parts. At present, the friction disc of the clutch is a circular integral structure, which has the advantages of: integral production, high efficiency, low cost, and the holes are pressed out at one time. However, this integral structure also has some disadvantages: due to the large number of holes in the integral structure, it is easy to have misalignment problems, which affects the installation. In addition, when the friction disc is worn, it needs to be replaced as a whole, which has high maintenance costs. In addition, the integral friction disc generates heat during friction, which easily causes the product to expand and crack due to heat. Utility Model Content

[0016] Figure 1 It is a schematic diagram of the structure of a split friction disc for a clutch;

[0017] Figure 2 for Figure 1 A top view of a split friction disc for the clutch shown; DETAILED DESCRIPTION

[0018] Example 1: See Figure 1 -- Figure 2 , In the figure, 1-lower screw layer, 2-upper friction layer, 3-connecting hole.

[0019] A split friction disc for a clutch comprises a friction disc body, wherein: the friction disc body is a non-integral circular ring structure, adopts a full circular ring split structure, and is composed of a sector-shaped circular ring segment, the circular ring segment is composed of an upper friction layer 2 and a lower screw layer 1 of different materials, the lower screw layer 1 has high strength, good impact resistance, and is not easy to be damaged, the upper friction layer 2 is made of friction material, has good wear resistance, the upper friction layer 2 and the lower screw layer 1 are connected together, and a connecting hole 3 is provided on the lower screw layer 1.

[0020] Optimal solution: two upper friction layers are arranged on the lower threaded layer at intervals, a gap is provided between the two upper friction layers, and a connecting hole is provided at the gap.

[0021] Preferred solution: the connecting hole 3 is a through hole or a countersunk hole. The figure shows a countersunk hole, but a through hole can also be used as long as the thickness of the nut is ensured to be less than the minimum wear height of the upper friction layer 2.

[0022] Preferred solution: the width of the upper friction layer 2 is smaller than that of the lower threaded layer 1, and the connecting holes 3 are arranged on the lower threaded layer 1 beside the upper friction layer 2. The number of connecting holes 3 depends on the size of the friction disk. There are three in each column in the figure, and two or four holes can also be set, which are not listed one by one.

[0023] Preferred solution: The upper friction layer 2 and the lower threaded layer 1 are vulcanized together, or bonded together, or threaded together, depending on the specific situation and will not be described in detail.

[0024] When in use, the friction disc body is connected to the clutch through the connecting hole 3 and the connecting bolts, and the driving or braking of the rotating parts is realized according to the situation. When the upper friction layer 2 reaches the wear limit, the connecting bolts are removed and a new friction disc body is replaced, which is convenient and quick.

[0025] The material of the lower screw connection layer 1 can be a polymer material (glass fiber and resin), a metal plate or a bakelite board, which has a certain strength and does not deform.

[0026] The upper friction layer 2 is mainly made of friction material (aramid fiber, resin, copper wire, graphene, barite powder), which has good wear resistance, stable friction coefficient, aging resistance, heat resistance, and is not easy to fail due to heat.

[0027] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the similarities are not repeated. The difference is that only one upper friction layer is provided on the lower threaded layer, which simplifies the structure and is suitable for small clutches or occasions using multiple friction disc bodies.

[0028] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification made according to the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
