AI Technical Summary
After assembly, the brake pads may experience uneven force due to accumulated errors, resulting in unequal braking force, reduced service life, uneven wear, and increased economic losses.
The design adopts a sliding connection between the camshaft and the float. The float has cycloidal ends and is fixed by a fixing pin. This balances the contact force of the upper and lower brake shoes, ensuring even contact during braking and improving braking efficiency and service life.
This achieves uniform force distribution on the upper and lower brake pads during braking, improving braking efficiency, extending brake pad life, and reducing uneven wear.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of brake, concretely is a brake structure. BACKGROUND
[0002] The existence of product processing cumulative error, when braking after assembly, camshaft exerts force on both sides of the shoe and makes the upper and lower shoe block displacement, the displacement of the upper and lower shoe block exists bias relative to the brake drum, causes the braking force to be not equal, reduces the brake efficiency, when braking, the upper shoe block has been friction braking, the lower shoe block has not contacted, leads to the service life reduction, the cumulative error of manufacturing link structure is big, causes the cumulative wear of upper and lower to be not equal, one shoe wear degree increases and then needs to be replaced, brings economic loss to the user.
[0003] Therefore, a brake structure is provided. SUMMARY
[0004] The utility model discloses a brake structure to solve the problem in the background art.
[0005] To achieve the above object, the utility model provides the following technical scheme:
[0006] A brake structure, comprising an upper shoe block and a lower shoe block, a camshaft is arranged between the upper shoe block and the lower shoe block, and a rocker arm is arranged on one side of the camshaft.
[0007] The camshaft is provided with a float block in sliding connection therewith.
[0008] Further, the float block is in cycloid type at both ends.
[0009] Further, the camshaft is provided with an inner groove, and the inner groove is in sliding connection with the float block.
[0010] Further, the float block is fixed through a fixed pin.
[0011] Compared with the prior art, the utility model has the beneficial effects that:
[0012] The uneven force of the upper and lower shoes on the brake drum is solved, the brake efficiency is improved, and the friction loss of the shoe is improved. BRIEF DESCRIPTION OF DRAWINGS
[0013] Fig. 1 The structure schematic diagram of the utility model is shown in the figure;
[0014] Fig. 2 The local enlarged structure schematic diagram of the utility model is shown in the figure. DETAILED DESCRIPTION
[0015] The technical scheme in the utility model embodiment will be described clearly and completely in conjunction with the drawings in the utility model embodiment.
[0016] Embodiment 1:
[0017] Please refer to Figs. 1-2 The utility model provides a technical scheme:
[0018] A brake structure, including upper shoe 1 and lower shoe 2, install camshaft 3 between upper shoe 1 and lower shoe 2, set up rocker arm 5 on one side of camshaft 3, and in order to facilitate the movement of float block 4, camshaft 3 is slidably connected with float block 4, wherein the both ends of float block 4 are in trochoidal type, which is convenient for contacting with shoe, and camshaft 3 is provided with inner groove, and the inner groove is slidably connected with float block 4, and float block 4 is fixed by fixing pin for convenient installation.
[0019] Working principle:
[0020] There is a float block 4 in the middle of camshaft 3, when camshaft 3 exerts force on both sides of shoe, due to cumulative error of processing, the upper and lower shoe plates are not uniformly contacted with the brake pot braking surface, and float block 4 can float up and down to balance the contact of both sides of shoe plate, so that the force is symmetrical, and both sides are uniformly contacted during braking, so as to increase the braking force and improve the service life.
[0021] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
