Title:
COMPOSITE BRAKE DISC CONNECTING ASSEMBLY, AND COMPOSITE BRAKE DISC
Document Type and Number:
WIPO Patent Application WO/2021/159854
Kind Code:
A1
Abstract:
Disclosed are a composite brake disc connecting assembly, and a composite brake disc. The composite brake disc connecting assembly comprises sleeves (1) and spring members (2). The sleeve (1) comprises an upper pressing plate (101), a lower pressing plate (102) and a connecting column (103), wherein a connecting hole (104) is provided in the center of the connecting column (103); a pair of U-shaped clamping grooves are provided between the upper pressing plate (101) and the connecting column (103) and between the lower pressing plate (102) and the connecting column; and the spring member (2) comprises a pair of elastic pieces and a connecting bridge (201). The composite brake disc comprises a brake disc cap (4), a friction ring (5) and a plurality of composite brake disc connecting assemblies, wherein the brake disc cap (4) is provided with disc cap notches (401) used for installing the spring members (2); the friction ring (5) is provided with installation holes (505) used for containing the connecting columns (103); and the friction ring (5) and the brake disc cap (4) are connected by means of fasteners (3) inserted in the connecting columns (103). The composite brake disc is simple in terms of structure, the friction ring (5) can move in the radial direction, and the degree of deformation of the brake disc is reduced, such that shaking during braking is prevented. The whole assembly process is simple, the number of parts is reduced, such that the production cost is reduced, and the source of process variation is reduced.
