Description

Technical Field

[0001] This utility model relates to the field of clutch face plate technology, specifically to clutch face plates used in gas engine commercial vehicles. Background Technology

[0002] Clutch face plates are a type of friction material. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Clutch face plates are the component materials that rely on friction to perform transmission functions. According to their uses, they can be divided into two categories: mechanical clutch face plates and automotive clutch face plates.

[0003] Existing clutch face plates require replacement of the friction plates after a period of use. However, in current situations, when the face plates are partially worn, the entire face plate often needs to be replaced, resulting in a significant waste of resources. Utility Model Content

[0008] Preferably, the fixing component includes a fixing plate with a square hole in the middle, second fixing bolts passing through both ends of the fixing plate, and threaded holes in the inner surface of the positioning groove. The second fixing bolts are threadedly connected to the mounting plate through the threaded holes.

[0009] Preferably, the mounting plate has a shaft hole in the middle, and a positioning ring is fixedly connected to the middle of the left and right sides of the mounting plate. Multiple shock-absorbing grooves are distributed circumferentially on the sides of the mounting plate, and the multiple shock-absorbing grooves are located between the shaft hole and the positioning ring. A shock-absorbing spring is provided inside the shock-absorbing groove.

[0010] Preferably, the limiting frame is T-shaped, with a limiting hole in the middle of the side of the limiting frame and a through hole in the middle of the top surface of the limiting frame, the through hole and the limiting hole being interconnected.

[0011] Preferably, a sliding groove is provided in the middle of the front and rear sides of the friction plate, and the friction plate is slidably connected to the limiting frame through the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When using this utility model, the friction plate is inserted along the limiting frame. Under the action of the spring, the limiting rod pops out into the limiting hole, thereby initially fixing the friction plate. The fixing plate is placed in the positioning groove, and both ends of the fixing plate are inserted into the end of the sliding groove. The second fixing bolt is screwed in, thereby further fixing the friction plate and preventing the friction plate from sliding during use.

[0014] 2. When using this utility model, the second fixing bolt is removed from the fixing plate by using a screwdriver or other tools, and a cylinder is inserted into the through hole. The cylinder moves along the arc surface of one end of the limiting rod, squeezing the limiting rod into the mounting groove, thereby releasing the limiting of the friction plate. The limiting component and the fixing component can be disassembled and recycled, so that the friction plate can be replaced. Attached Figure Description
