Embodiment 1

[0033] A rubber pad type fixed caliper disc brake, including a caliper body and a friction block 1 installed on the caliper body, wherein the caliper body includes an inner caliper body 2 and an outer caliper body 3, and the inner caliper body 2 and the outer caliper body 3 pass through Fixing bolts secure the connection.

[0034] A return component 4 is installed on the pliers body, and the friction block 1 is installed on the pliers body through the return component 4. The return component 4 includes an elastic deformation sleeve 5 and a fastening screw 6. A mounting hole 7 is provided on the pliers body, and the elastic deformation The sleeve 5 is installed in the installation hole 7, and the elastic deformation sleeve 5 includes an upper limit seat 8, a lower limit seat 9 and a connection sleeve 10 connecting the upper limit seat 8 and the lower limit seat 9, and the connection sleeve 10 is inserted in the installation hole 7, The upper limit seat 8 and the lower limit sea...

Embodiment 2

[0053] Compared with Embodiment 1, this embodiment also has the following schemes: in this embodiment, a piston chamber 14 is arranged in the caliper, a sealing groove 16 is arranged in the piston chamber 14, a rectangular sealing strip 17 is installed in the sealing groove 16, and the piston chamber 14 A piston 18 for pushing the friction block 1 to move is arranged inside, and the inner ring of the piston 18 and the rectangular sealing groove 16 has an interference fit. The caliper body includes an inner caliper body 2 and an outer caliper body 3, on which a piston 18 and a rectangular sealing strip 17 are installed.

[0054] During the braking process: the piston 18 moves outward under the action of oil pressure, and the inner side of the rubber rectangular sealing strip 17 moves with the piston 18 under the action of interference assembly, while the outer side of the rectangular sealing strip 17 is limited by the sealing groove 16 , fixed at the installation position, so t...

Embodiment 3

[0058] The difference between this embodiment and Embodiment 1 is that: both the inner pliers body 2 and the outer pliers body 3 are provided with 4 sets of return components 4 for connecting the friction block 1 .

Abstract

The invention relates to the field of brakes, and discloses a rubber gasket type fixed caliper disc brake. A caliper body is provided with a return assembly, a friction block is installed on the caliper body through the return assembly, the return assembly comprises an elastic deformation sleeve and a fastening screw, the caliper body is provided with a mounting hole, and the elastic deformation sleeve is installed in the mounting hole. The elastic deformation sleeve comprises an upper limiting seat, a lower limiting seat and a connecting sleeve connecting the upper limiting seat and the lower limiting seat, the connecting sleeve is inserted into the mounting hole, the upper limiting seat and the lower limiting seat are limited to the upper side end face and the lower side end face of the mounting hole respectively, the fastening screw penetrates through the elastic deformation sleeve, and the lower end of the fastening screw is fixedly connected with the friction block. The upper end of the fastening screw abuts against the interior of the upper limiting seat. The rubber gasket type fixed caliper disc brake has the advantages of simple structure, low cost, high return effect, no noise vibration and the like.

Description

technical field [0001] The invention relates to the field of fixed caliper disc brakes, in particular to a rubber pad type fixed caliper disc brake. Background technique [0002] Fixed caliper disc brakes have become one of the preferred solutions for front brakes of new energy vehicles due to their advantages of large braking torque and good thermal stability. The current fixed caliper disc brake scheme generally has the problem of braking noise and dragging torque. The reason is that the friction block does not fully return after the brake is released, that is, the brake disc and the friction block are not completely separated. This is the problem. Starting from this project, a rubber pad return structure is designed in this project, which can effectively make the friction block return to its position after the brake is released, and separate from the brake disc, reducing the risk of brake noise and drag torque And other issues. [0003] The friction block return mechani...
