Problems solved by technology

[0004] Some wheels need to be equipped with drum brakes, and some wheels need to be equipped with disc brakes, but the above-mentioned patented wheels are designed and manufactured separately with disc brakes or drum brakes. There is a clear distinction between the two, and they cannot be refitted with each other. Remanufacturing is very troublesome

Embodiment 1

[0032] Such as figure 1 and figure 2As shown, the present embodiment is a wheel hub that can be refitted with a drum brake and a disc brake, which includes a mounting flange 1 for installing a disc brake disc, a spoke 2, a cylindrical brake drum 3 and a rim 4, and the brake The drum 3 is located in the middle of the rim 4 and the two are coaxially arranged. The brake drum 3 is fixedly connected to the rim 4 through the spokes 2. The two ends of the brake drum 3 are respectively an open end 35 and a closed end 36. The brake drum 3 includes The tubular body 31 and the bottom 32 are in an integrated structure, and the bottom 32 closes one end of the body 31 to form a closed end 36 of the brake drum 3 .

[0033] Such as Figure 1-Figure 9 As shown, a bushing 5 passing through the closed end 36 is fixed at the center of the closed end 36. The hub includes a cover plate 10 independent of the brake drum 3, and the cover plate 10 is fixed to the opening of the brake drum 3 by weldi...

Embodiment 2

[0038] The general content of this embodiment is the same as that of the first embodiment, except that, as another solution, the cover plate 10 of this embodiment is detachably fixed to the open end 35 of the brake drum 3 . The detachable fixing at the open end 35 of the cover plate 10 and the brake drum 3 is connected and fixed by a threaded member or fixed by a buckle connection. The threaded connection generally includes screws or bolts, which are relatively easy to install and disassemble. The advantage of detachable fixing is that it can be disassembled conveniently, which improves the convenience of modification.

Embodiment 3

[0040] The general content of this embodiment is the same as that of the first embodiment, except that, as another solution, the cover plate 10 of this embodiment is fixed to the open end 35 of the brake drum 3 by riveting. The rivet connection requires a certain degree of violent destruction, relatively speaking, the damage is not large, the cost is also low, and the disassembly is more convenient.

Abstract

The invention provides a hub enabling mutual refit of a drum brake and a disc brake, belonging to the technical field of locomotive hubs. The technical problem of the existing hub that mutual refit of a disc brake or drum brake cannot be realized is solved. The hub enabling mutual refit of a drum brake and a disc brake comprises a mounting flange for mounting a disc brake plate, a spoke, a cylindrical brake drum and a rim, wherein the brake drum is fixedly connected with the rim through the spoke; the two ends of the brake drum are an open end and a closed end respectively; the hub also comprises a cover plate independent of the brake drum; the cover plate is fixed at the open end of the brake drum through welding, in a detachable manner or through rivet connection; a bushing II penetrating through the cover plate is inserted into the middle of the cover plate; the inner end of the bushing II is fixedly connected with the cover plate; the outer end of the bushing II is fixed with the mounting flange; and the bushing I, the bushing II and the brake drum are coaxially arranged. In the invention, mutual refit of the drum brake and disc brake can be realized, the universality is high, the convenience of enterprise production is greatly improved, and the stock pressure is reduced.

Description

technical field [0001] The invention belongs to the technical field of motorcycle hubs and relates to a hub in which drum brakes and disc brakes can be refitted with each other. Background technique [0002] The drum brake is composed of the brake base plate, the brake cylinder, the brake shoes and other related connecting rods, springs, pins, and brake drums. At present, it is generally installed on the rear wheel. The cost of drum brakes is lower, and the absolute braking force is higher. The inner surface of the brake drum of the drum brake is the position where the brake device generates the braking torque. In the case of obtaining the same braking torque, the diameter of the brake drum of the drum brake device can be much smaller than the brake disc of the disc brake, and the drum brake can only be installed in the limited space of the rim. [0003] Disc brakes are composed of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When brakin...
