The invention relates to a brake clamp unit capable of recognizing lever deformation. The brake clamp unit comprises a brake cylinder, a hanging bracket, brake pad carrier assemblies, external lever assemblies and a shell assembly. The brake cylinder comprises a cylinder body. A piston, a guide spring, a guide nut, a taper sleeve, an adjusting shaft assembly and a clearance adjustment nut assembly are arranged inside the cylinder body. The clearance adjustment nut assembly comprises a clearance adjustment nut, a clearance adjustment sleeve and a clearance adjustment spring. A groove extending in the axial direction of the clearance adjustment sleeve is formed in the external circumferential face of the clearance adjustment sleeve, and a relief clearance device is arranged in the groove. The guide nut is connected with one end of the guide spring, and the other end of the guide spring is connected with a cushion block. The external circumferential face of the cushion block is sleeved with a piston tube cover. The piston tube cover is connected with an internal thread of a thrust bush. A thrust bush spring is arranged between the thrust bush and the taper sleeve. The brake clamp unit capable of recognizing lever deformation has the advantages that the thrust bush spring can recognize excessive elastic deformation of an external lever, clearance adjustment triggered by the excessive elastic deformation of the external lever is avoided, and fixation of the disk relief clearance is guaranteed.
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. like 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 into...
