Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a combined anti-lock brake drum for heavy-duty vehicles in view of the above-mentioned technical deficiencies. The brake drum is equipped with a brake device on one side. The brake shoes evenly arranged inside the braking device can not only improve the braking effect, but also solve the problem that the traditional brake shoes are easily driven by the brake drum and brake to death during the braking process; The structure of the driving device is set, and the brake shoes are driven by the expander inside the driving device, so that the combined driving structure increases the heat dissipation space inside the brake drum, and solves the problem of frequent braking of the traditional brake drum. When braking, it is easy to overheat and make the braking effect poor

Abstract

The invention relates to the technical field of brake drums, in particular to a combined anti-lock brake drum for a heavy-duty car. A structure of arranging a brake device on one side of the brake drum is adopted; when the brake effect is improved through brake shoes uniformly arranged in the brake device, the locking problem of traditional brake shoes due to easier driving by the brake drum in the brake process is solved; a structure of arranging a driving device in the brake device is adopted; and the brake shoes are driven through an expander in the driving device, so that the internal heatdissipating space of the brake drum is enlarged by using the combined driving structure, and the problem of weaker brake effect caused by easy overheating due to frequency braking of a traditional brake drum is solved.

Description

technical field [0001] The invention relates to the technical field of brake drums, in particular to a combined anti-lock brake drum for heavy vehicles. Background technique [0002] At present, in the selection of braking methods, drum brakes are generally used for heavy-duty vehicles because the cost of drum brakes is lower and the absolute braking force is higher. However, drum brakes are easy to brake during the braking process. The situation of automatic braking occurs, which leads to high heat generation of the brake drum, which is very prone to brake failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined anti-lock brake drum for heavy-duty vehicles in view of the above-mentioned technical deficiencies. The brake drum is equipped with a brake device on one side. The brake shoes evenly arranged inside the braking device can not only improve the braking effect, but also solve the problem that th...
