Description

Technical Field

[0001] The present application relates to the technical field of brakes, and in particular to a floating brake disc and an assembly tool thereof. Background Art

[0002] Disc brake disc is a common brake device. It uses the action of the brake caliper to make the brake caliper contact with the brake disc body to generate friction and form braking. In order to obtain a larger braking torque, high-performance brake systems use large-diameter disc brake discs. When braking, the contact and friction between the brake caliper and the brake disc body will generate high temperature, and the brake disc body will expand thermally. If it is an integrated disc brake disc, the outer edge that expands at high temperature and the colder bracket are rigidly connected, which will produce strong internal tensile stress. In severe cases, it will cause the disc body to twist and deform laterally. The larger the diameter of the disc body, the more obvious this deformation is. In order to avoid brake failure caused by severe thermal deformation of the disc brake disc, engineers designed a floating disc brake disc, which separates the friction surface of the outer edge of the disc and the inner joint bracket, and connects them with a special non-rigid structure in the middle to form a floating connection structure. In this way, the friction surface of the disc and the joint bracket become relatively independent force-bearing surfaces. When the friction surface of the disc expands due to heat, the floating connection structure allows a certain amount of free longitudinal expansion space for the friction surface of the disc, eliminating the conditions for internal tensile stress between the joint bracket, thereby preventing the friction surface of the disc from twisting and deforming due to uneven heating, making the brake more stable and reliable. At the same time, the floating brake disc also achieves the technical effect of reducing brake vibration and brake caliper alignment.

[0003] During the assembly process of the floating brake disc, the joint head and the disc body need to be connected through multiple connecting components, and the multiple connecting components need to be assembled together into the corresponding mounting holes of the disc body. The number of connecting components is as many as more than ten, and the mounting holes on the disc body are small and difficult to align; although there are some automatic assembly equipment in the prior art, these automatic assembly equipment have high production and manufacturing costs and poor versatility; most floating brake discs still rely on manual operation for assembly. For the floating brake discs in the prior art, the assembly operation process is relatively cumbersome, the accuracy is difficult to guarantee, and the efficiency is low. Utility Model Content
