A brake caliper unit capable of recognizing lever deformation

Abstract

The invention relates to a brake caliper unit capable of identifying the deformation of a lever, which comprises a brake cylinder, a hanger, a brake pad holder assembly, an external lever and a housing. The brake cylinder includes a cylinder body with a piston, The guide spring, the guide nut, the taper sleeve, the adjustment shaft and the gap adjustment nut are composed of the gap adjustment nut, the gap adjustment nut, the gap adjustment sleeve and the gap adjustment spring. The groove is extended, and the groove is provided with relief clearance settings; the guide nut is connected with one end of the guide spring, and the other end of the guide spring is connected with the cushion block, and the piston tube cover is set on the outer peripheral surface of the cushion block, and the piston tube cover and the The thrust sleeve is internally threaded, and a thrust sleeve spring is arranged between the thrust sleeve and the taper sleeve. The advantage of the present invention is that the thrust sleeve spring can identify excessive elastic deformation of the external lever, avoid gap adjustment triggered by excessive elastic deformation of the external lever, and ensure that the disc relief gap is fixed.

Description

technical field [0001] The invention relates to a brake device, in particular to a brake caliper unit capable of identifying the deformation of a lever, and belongs to the technical field of vehicle brake systems. Background technique [0002] The brake caliper unit is one of the key parts of the brake system and plays a vital role in the safe operation of the vehicle. Such as figure 1 As shown, the brake caliper unit generally includes components such as a brake cylinder 1', a brake caliper 2', a brake pad 3' and a brake disc 5', and the brake caliper 2' includes a The external lever 4' also includes hangers, brake pad holders and other parts. The magnification of the external lever 4' is 2. Since the technical conditions of the brake caliper unit stipulate that the disc release clearance of the brake caliper unit is 3 on both sides. ~6mm, the theoretical relief gap of the disc is designed to be 4.5mm on both sides. When the vehicle brakes, the compressed air is filled i...

AI Technical Summary

Problems solved by technology

[0009] To sum up, it can be seen that the current gap adjustment function inside the brake cylinder 1' has flaws in the structural design, which leads to the brake regulator not being able to identify it when the elastic deformation of the external lever 4' increases, thus triggering an unnecessary gap Adjustment
