Embodiment Construction

[0014] Such as figure 1 and figure 2 A specific embodiment is shown, which is an improvement of the existing disc brake. The existing disc brake includes a caliper body 6, a bracket 3, a brake disc 1 and a brake pad 2, and the caliper body 6 is slidably set On the bracket 3, a brake gap automatic adjustment mechanism is connected between the caliper body 6 and the bracket 3. When the brake pad 2 or the brake disc 1 starts to wear, the brake gap automatic adjustment mechanism makes the caliper body 6 relative to the bracket 3. Sliding, keeping the gap between the brake pad 2 and the brake disc 1 constant. This patent adds a detection body 4 on the basis of the aforementioned prior art. The length direction of the detection body 4 is in the same direction as the axial direction of the brake disc 1. One end of the detection body 4 is kept on the bracket 3, and the detection body 4 can be directly It is fixed on the support 3, and one end of the detection body 4 can also be kep...

Abstract

The invention discloses a disc brake capable of detecting abrasion losses of a break lining block. The disc brake comprises a pliers body, a support, a brake disc and a break lining block, the pliers body is arranged on the support in a sliding mode, and a break gap automatic adjusting mechanism is connected between the pliers body and the support; and the disc brake further comprises a detection body, the length direction of the detection body and the axial direction of the break disc are identical, one end of the detection body is maintained on the support, the other end stretches out of the pliers body, and the detection body and the pliers body are connected in a sliding mode. According to the disc brake, the abrasion losses of the break lining block can be detected at any time by calculating the abrasion losses of the break lining block through the variable quantity of the stretching length of the detection body and break disc unilateral abrasion losses. Compared with prior limit abrasion loss sensors, the disc brake can help drivers to judge teal-time abrasion losses of the break lining block, the break lining block is changed in time before the break lining block is abraded to the limit under the condition that friction materials are fully used, the cost is reduced, and the break safety is guaranteed simultaneously.

Description

technical field [0001] The invention relates to a disc brake capable of detecting the amount of wear of a brake pad. Background technique [0002] Chinese patent CN201020649105.7 discloses a heavy-duty vehicle disc brake pad assembly capable of alarming. It consists of a pad assembly, a rivet, and a metal sheet, and the metal sheet is fixed on the pad assembly by the rivet. When the pad assembly wears to the limit, the metal plate will rub against the brake disc, and an abnormally harsh warning sound will be issued to remind the driver to replace the pad assembly in time to avoid brake failure and improve safety. But when it alarms, due to many practical problems, the pad assembly cannot be replaced immediately, which will lead to brake failure. [0003] Chinese patent CN201120515544.3 discloses a disc brake caliper assembly, including a brake pad pressure spring and a brake pad engaged between the brake pad pressure spring. Brake pad wear warning indicator and continuous ...
