Wear-resistant disk

Abstract

The invention discloses a wear-resistant disk. The wear-resistant disk comprises a carrying disk which is used for assembling a wheel hub and made of a light metal material; a plurality of annular holes are annularly formed in the carrying disk; two circular annular wear resistance frames are arranged on two sides of the carrying disk respectively to provide a wear resistance effect; both wear resistance frames are made of irony metal; a plurality of notches are annularly formed in the outer sides of both wear resistance frames; on the inner side of each wear resistance frame, a protruded surface is formed on the inner wall of each notch; the notches of both wear resistance frames are flush with the annular holes of the carrying disk, the protruded surface of each notch is embedded into each annular hole from two sides of the carrying disk; and the two relative protruded surfaces are combined correspondingly in the annular holes of the two wear resistance rings to ensure that the carrying disk and the two wear resistance frames are integrated, and the shearing force which is produced by a brake is transmitted to the carrying disk by the wear resistance frames. The wear-resistant disk has the advantages of light weight, wear resistance and high structural strength and density, and reduces production cost.

Description

technical field [0001] The invention relates to a wear-resistant disc, in particular to a brake frame made of ferrous metal assembled on both sides of a carrier made of light metal, which takes into account light weight and wear resistance, and has excellent structural strength and density. platter. Background technique [0002] Stunt cars or rock climbing cars need a brake system with excellent braking performance in order to be able to stop in an instant to perform changes in maneuvers or to avoid the danger of stalling downhill. In order to improve the braking ability of the braking system, the bicycle industry has started to develop and research the grip of the system, the sensitivity of the calipers, the braking force, the friction of the disc, and the wear resistance of the disc. [0003] Taking the disc as an example, there is a "brake disc structure with composite material" among the existing discs. And it is also a disk-shaped outer disc body. The center of the tw...

Problems solved by technology

[0004] Although the above-mentioned discs have the characteristics of wear resistance and light weight, however, due to the assembly of the outer disc body and the inner disc body, metallurgical procedures such as smelting, rolling, extrusion, stretching, cutting, cutting or sintering must be carried out to the outside. Part or all of the plates of the disc body and the inner disc body can be assembled and combined with each other. It can be seen that the processing and assembly procedures of this type of disc are obviously too complicated and require high production costs. , it is necessary to improve
