Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutches, and more specifically, to a driven plate assembly of a heavy-duty vehicle clutch with replaceable friction plates. Background Technology
[0002] The driven disc of a car clutch is an essential and easily worn part in a manual transmission vehicle. The friction plates on the traditional driven disc are usually directly glued to the driven disc and cannot be removed. When the friction plates are damaged, repair is difficult and replacement is inconvenient. In addition, the friction plates on the traditional driven disc have a simple structure and low surface roughness, which makes it easy to generate a lot of heat during braking that cannot be dissipated quickly, resulting in poor performance.
[0003] The utility model patent CN213117203U discloses a replaceable friction plate driven disc assembly for a heavy-duty automotive clutch, belonging to the field of driven discs. It includes a driven disc body, with friction plates connected to both sides of the body. The friction plates have evenly spaced mounting grooves on their sides, and through holes at the ends of the mounting grooves. Bolts are slidably connected inside the through holes, with the ends of the bolts threaded into threaded grooves on the sides of the driven disc body. Elastic washers are fixedly installed around the through holes at the ends of the mounting grooves, with their sides contacting the ends of the bolts. Wear-resistant protrusions are evenly fixedly installed on the sides of the friction plates, and heat dissipation grooves are evenly spaced between these protrusions. This replaceable friction plate driven disc assembly for a heavy-duty automotive clutch allows the friction plates to be fixed to the driven disc body through the engagement of the bolts and threaded grooves, making installation, removal, and replacement simple and convenient.
[0004] In the above-disclosed structure, the friction plate is directly connected by screws, lacking a positioning boss for limiting installation. Moreover, the connection surface is small, which easily leads to low connection strength and poor safety in use. Furthermore, it can only assist in heat dissipation on one side surface, lacking an annular auxiliary groove for internal heat dissipation, resulting in poor adaptability and requiring improvement. Utility Model Content
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a replaceable friction plate heavy-duty vehicle clutch driven plate assembly. The friction plate is connected by a positioning boss on one side of the mounting plate, and can be installed separately with the positioning plate and fixing screws. This will not cause interference to the friction surface, and can also ensure sufficient friction area. It can be replaced and used. At the same time, by setting an annular heat dissipation groove, combined with the inner annular auxiliary groove, it can ventilate and dissipate heat from both sides, improve cooling efficiency, ensure safety in use, and facilitate combined use.
[0006] To solve the above problems, the present invention adopts the following technical solution.
[0007] A replaceable friction plate heavy-duty vehicle clutch driven plate assembly includes a mounting plate. A positioning boss is fixedly connected to one side surface of the mounting plate.

A positioning plate is provided on the outer circular surface of the friction plate, and the positioning plate is fixedly connected to one side surface of the mounting plate. Fixing holes are provided on the surfaces of both the mounting plate and the positioning plate. Fixing screws are installed in the internal threads of the fixing holes and are pressed and connected to one side surface of the positioning plate. An annular heat dissipation groove is provided on the outer surface of the friction plate. A spacer is fixedly connected to the inner side of the annular heat dissipation groove, and the spacer is fixedly connected to one side of the inner surface of the friction plate.
[0008] Furthermore, the positioning groove is provided with an annular auxiliary groove inside, and the annular auxiliary groove and the circular through hole are concentric circles.
[0009] Furthermore, the side of the annular auxiliary groove is provided with a combined connecting groove, which is distributed at equal angles on one side surface of the positioning groove.
[0010] Furthermore, the mounting plate has internal heat dissipation holes, one end of which is aligned with one side of the combined connecting groove. By setting an annular auxiliary groove and the combined connecting groove inside, combined with the heat dissipation holes, an internal flow channel can be formed, thereby allowing air circulation, facilitating auxiliary heat dissipation, ensuring the stability of internal and external temperatures, and facilitating installation and use.
[0011] Furthermore, there are six fixing holes and six fixing screws, which are distributed at equal angles on the surface of the positioning plate.
[0012] Furthermore, the annular heat dissipation groove has three layers, which are concentrically distributed on the outer surface of the friction plate.
[0013] Furthermore, the friction pad is fixedly attached to one side surface of the mounting plate and assembled on the outer surface of the positioning boss. It can be assembled and fixed by multiple fixing screws distributed at equal intervals, which is convenient for connecting the friction pad to the mounting plate for use. It can also be disassembled for replacement and maintenance, which is highly adaptable and ensures the safety of braking.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] (1) This solution connects the friction plate to the positioning boss on one side of the mounting plate, and combines the positioning plate and fixing screws for separate installation. This will not cause interference to the friction surface, and can also ensure sufficient friction area for replacement. At the same time, by setting an annular heat dissipation groove, combined with the inner annular auxiliary groove, it can ventilate and dissipate heat from both sides, improve cooling efficiency, ensure safety of use, and facilitate combined use.
[0016] (2) By setting an annular auxiliary groove and a combined connecting groove inside, combined with heat dissipation holes, an internal flow channel can be formed, which allows air circulation, facilitates auxiliary heat dissipation, ensures the stability of internal and external temperatures, and is conducive to installation and use.
[0017] (3) Multiple fixing screws are distributed at equal intervals, which can be combined and fixed, making it easy to connect the friction plate to the mounting plate for use. It can also be disassembled for replacement and maintenance, which is highly adaptable and ensures the safety of the brake. Attached Figure Description
