[0007] A pressing component, mounted on the mounting plate, used to push the piston into the piston mounting hole;

[0008] The locking component is mounted on the mounting plate and is used to abut against the protrusion on the inner side of the brake housing to prevent the pressing component from driving the supporting component to move during the process of pushing the piston.

[0009] In some embodiments, the clamping component is a bolt I, and a threaded hole I is provided in the middle of the mounting plate. The threaded hole I is coaxially arranged with the piston mounting hole. The bolt I is screwed into the threaded hole I. By continuously screwing in the bolt I, the circumferential rotation is converted into axial linear motion of the bolt I, so that the bottom of the bolt I pushes the piston to be pressed into the piston mounting hole.

A bolt II is screwed into each threaded hole II, and the lower part of the bolt II extends into the groove on the inner side of the brake housing and is close to the protrusion, so as to prevent the supporting component from rotating itself during the process of screwing in the bolt I.

[0011] In some embodiments, the mounting plate is provided with a plurality of rows of threaded holes II arranged at intervals, which are used to adjust the installation position of the bolts II and to match different types of brake housings so that the bolts II can be closely attached to the protrusions.

[0012] In some embodiments, at least one threaded hole III is provided at one end of the mounting plate close to the inner gear wall of the brake housing, a bolt III is screwed into each of the threaded holes III, at least one bolt IV is installed on the top circumferential surface at the edge of the brake housing, and the bolt III is bound together with the bolt IV through a connecting component.

[0013] In some embodiments, the connecting component is a wire or a cable tie, and the bolt III and the bolt IV are bound together by tightening the wire or tying the cable tie.

[0014] In some embodiments, the support component is connected together by a base plate, a vertical plate and a mounting plate by welding, the base plate and the mounting plate are arranged in parallel, and the length dimension of the mounting plate is greater than the length dimension of the base plate.

[0015] In some embodiments, the vertical plate is configured as a forward convex arc surface, so that the vertical plate can be completely attached to the inner ring side circumference of the brake housing.

[0016] In some embodiments, the base plate is provided with a plurality of mounting holes for fixing the base plate to the brake housing via a plurality of fasteners.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The supporting components only include a bottom plate, a vertical plate and a mounting plate, which are fixed together by welding, and the structure is simple;

[0019] By screwing the bolt I to slowly press it down, the piston is pushed down into the piston hole. This installation method makes the piston evenly stressed and the piston is not prone to deflection during the installation process.

[0020] The protrusion in the brake housing exerts force on bolt II to prevent the support component from rotating itself during the process of tightening bolt I;

[0021] The bolt IV on the brake housing and the bolt III on the support component are bound by wire or cable ties to further reduce the rotation of the support component itself. BRIEF DESCRIPTION OF THE DRAWINGS
