Floating disc

Abstract

The invention discloses a floating disc. The floating disc comprises an outer ring disc body, an inner disc body and a plurality of combinationassemblies. A plurality of first assemblingparts are arranged on the inner ring side of the outer ring disc body. A plurality of second assembling parts corresponding to the first assembling parts are arranged on the outer circumference of the inner disc body. Each combination assemblycomprises a fixing and combining column and an embedding and abutting piece. Each embedding and abutting piece is provided with an assembling hole. Each embedding and abutting pieceis provided with a plurality of limiting pieces at the inner hole edge of the corresponding assembling hole, and the limiting pieces extend towards the center of the assembling hole. The fixing and combining columns penetrate through the first assemblingparts of the outer ring disc body, the second assembling parts of the inner disc body and the assembling holes. The limiting pieces obliquely extend in the direction in which the fixing and combining columns penetrate through the assembling holes and are forced to abut against the outer circumferences of the fixing and combining columns. The fixing and combining columns of the combination assembliespenetrate through the outer ring disc body and the inner disc body, so that the outer ring disc body and the inner disc body are combined. The embedding and abutting pieces penetrate through the tail ends of the fixing and combining columns, so that the limiting pieces of the embedding and abutting pieces are made to abut against the fixing and combining columns, and the combined positioning effect is achieved. According to the floating disc, the fineness of the first assemblingparts and the fineness of the second assembling parts can be lowered; machining processes are simplified, work time is shortened, and machining cost is reduced; both disassembly and assembly are easy; the service life of the floating disc is prolonged due to the fact that the outer ring disc body and the inner disc body can be used repeatedly.

Description

technical field [0001] The present invention mainly relates to a floating disc, in particular to a disc that can be quickly disassembled and assembled. Background technique [0002] The disc is fixed on the wheel frame and can rotate synchronously with the wheel frame, and the disc uses the disc brake caliper to make the disc clamp produce friction, so that the disc slows down and then forces the wheel frame to slow down, and even stops the disc from rotating. The function of braking is achieved by stopping the rotation of the wheels. [0003] The discs in the prior art are mainly composed of inner discs and outer discs with different materials. The inner disc is slightly circular, and its outer periphery is provided with several half-holes, and the outer disc is in the shape of a circle. In the center of the outer disc, there is a hollow part for the inner disc to fit together, and several symmetrical semicircular holes are also provided on the periphery of the hollow part...

AI Technical Summary

Problems solved by technology

[0005] The existing technology is to directly combine and fix the pins on the inner disc and the outer disc, while the "disc for bicycles" uses a rivet structure to fix the rotor component to the installation component, and the rivet is directly combined with the rotor component. and installation components, in this way, the structure of the inner disc, outer disc, rotor components and installation components will be damaged during the process of disassembly and assembly, resulting in the disc, outer disc, rotor components and The structural deformation of the installation components makes it difficult to reuse

Furthermore, the combination of the inner disk, the outer disk, the rotor component, and the installation component is combined by riveting. The size and size of the hole diameter of the above-mentioned combination component must be accurately grasped in the production, otherwise it will be damaged. There are situations where it is difficult to combine, so the processing method of riveting is relatively complicated and the process is more complicated. At the same time, it is difficult and easy to damage the structure of the disc in the process of disassembly and assembly.
