Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disc brakes, and more specifically to an improved disc brake assembly. Background Art
[0002] The rotating element in the friction pair of a disc brake is a metal disc that works on the end surface, called a brake disc. The friction element clamps the brake disc from both sides to produce braking. There are many structural forms of fixed elements, and disc brakes can be roughly divided into two categories: caliper disc type and full disc type.
[0003] In the existing disc brakes, the selection of brake materials is particularly important. The selection of brake materials has a relatively important influence on the braking performance. During the braking process, when the selected brake material is softer, the friction plate is more likely to fall off, resulting in insufficient braking force. When the selected material is harder, although the friction plate can be suspended for a long time, it will aggravate the wear of the friction plate surface, thereby reducing the braking performance. Therefore, how to provide a braking structure that can ensure the suspension of the friction plate while reducing its surface wear is particularly important. In view of this, we propose an improved disc brake disc assembly. Utility Model Content

A spline sleeve 2 is sleeved on the surface of the traction machine rotating shaft 1. By setting the spline sleeve 2, the traction machine rotating shaft 1 can be connected to the brake assembly 4, so that the traction machine rotating shaft 1 can drive the brake assembly 4 to rotate while rotating, and the connection between the two is more stable during the movement process. An adjustment plate 5 is connected in the middle of the spline sleeve 2 through a screw. The spline sleeve 2 is fixed to the traction machine rotating shaft 1 through a flat key groove 6. By setting the flat key groove 6, it is convenient to disassemble between the spline sleeve 2 and the traction machine rotating shaft 1. At the same time, the structure is simple, which improves the convenience for disassembly. During connection, it can adapt to the high-speed operation of the traction machine rotating shaft 1, has strong bearing capacity, avoids derailment between the spline sleeve 2 and the traction machine rotating shaft 1, and improves the connection stability and operation efficiency of the two. The inner hole of the spline sleeve 2 is in interference fit with the traction machine rotating shaft 1. The surface of the spline sleeve 2 is provided with a plurality of radially arranged pattern grooves. The spline sleeve 2 is meshed and connected with an iron disc tooth sleeve 3 through the pattern grooves. The length of the spline sleeve 2 is lower than that of the iron disc tooth sleeve 3.
[0021] In the embodiment of the present utility model, a brake assembly 4 is arranged on the outer surface of the iron disc tooth sleeve 3. The brake assembly 4 includes a brake disc 401. The brake disc 401 is connected with a friction plate 402 through bolts. The material of the brake disc 401 is set as Q345B (magnetic conductive material: low-carbon steel C≤0.2%). By setting the material of the brake disc 401, the material of the brake disc 401 is changed to a magnetic conductive material, which will generate magnetic adsorption after being electrified.
