Description

Conveying ring of full-disc brake

Technical Field

The utility model relates to a vehicle brake field especially relates to a conveying ring of full disc brake.

Background

The rotating element in a friction pair of a disc brake is a metal disc working with end faces, called a brake disc. The friction elements grip the brake disc from both sides to produce braking. The fixing elements have various structural forms, and can generally divide the disc brake into a caliper disc type and a full disc type.

The disc brake may be classified into a floating disc brake and a floating caliper brake, in which the brake disc slides with respect to the hub and the caliper body slides.

In general, the caliper body of a floating caliper brake can move axially, but the brake disc is fixed to the hub and cannot slide in the direction of the axle relative to the hub. The floating caliper type brake generally adopts a wheel hub which is universal in the industry, and only one side of a brake disc is fixedly connected directly through a bolt, and the connection mode has a plurality of flaws, such as overlarge unilateral stress of the brake disc and the phenomenon of early cracking of the outer side easily occurs.

In general, a caliper body of a floating disc brake is fixed, and a brake disc slides in an axle direction with respect to a hub through a guide structure (guide groove), but rotates together with the hub in a circumferential direction, thereby transmitting a braking force. In general, a hub of a floating disc brake needs a special design, and a guide groove for sliding a brake disc is designed on the hub. The brake disc is direct to be connected with wheel hub, directly leads to wheel hub temperature to rise fast easily, and wheel hub bearing seals oil leak and bearing damage etc.. Greatly reducing the safety and the service life of the hub.

Most of the disc brakes in the prior art are floating caliper type brakes, and floating disc type structure brakes are generally used for full disc type brakes. Since the market share of the floating disc type structure brake (full disc type brake) is small, the floating disc type structure in the prior art needs to use a special hub. For example, some special hubs adopting a floating disc type structure have guide grooves on the side surface, so that the design of the floating disc hub and the floating caliper type hub cannot be commonly used. The universality of the floating disc type structure is not strong due to the special hub, and the hubs can not be interchanged, so that the application scenes of the brake with the floating disc type structure are fewer.
