Automobile brake drum with high compressive strength

Abstract

The invention discloses an automobile brake drum with high compressive strength. The automobile brake drum comprises a first shell and a second shell, wherein the inner wall of one side of the first shell is provided with a clamping groove, the interior of the clamping groove is scoff with a wear-resistant layer, the outer wall of one side of the wear-resistant layer is provided with diamond bulges distributed at equal intervals, the outer wall of one side of the wear-resistant layer spiral grooves distributed at equal intervals in an circular way, the fringe of inner wall of one side of the first shell is provided with circularly distributed arc grooves, the center of the inner wall of one side of the first shell is provided with a sleeved hole, the inner wall of the sleeved hole is welded with a strengthening rib, and the inner wall of one side of the first shell is provided with mounting holes distributed at equal intervals in an circular way. By means of the automobile brake drum with high compressive strength, the friction resistance with the surface of a brake chip can be improved, the brake efficiency can be improved, the relative air flow can be increased through the gap, the heat dissipation efficiency of the heat caused by the brake friction can be improved, the problem of lowering compressive strength due to brake overheating of a device can be prevented and the durability of the device can be further improved.

Description

technical field [0001] The invention relates to the technical field of automobile brake drums, in particular to an automobile brake drum with high compressive strength. Background technique [0002] Cars are one of the most commonly used vehicles in people's daily production and life, and brake drums are an important part of car brake systems. Brake drums are frictional parts of drum brakes. In addition to the required strength and stiffness, there should be as high and stable a coefficient of friction as possible. [0003] At present, after the brake drums used in existing automobiles are used for a long time, a large amount of heat will be generated during the use of the brake drums. If the brake drums are not dissipated in time, the compressive strength of the brake drums will be reduced. Therefore, it is necessary to Perform rapid heat dissipation to improve the compressive strength of the brake drum, and the existing brake drums for automobiles cannot meet actual needs...

Problems solved by technology

[0003] At present, after the brake drums used in existing automobiles are used for a long time, a large amount of heat will be generated during the use of the brake drums. If the brake drums are not dissipated in time, the compressive strength of the brake drums will be reduced. Therefore, it is necessary to Perform rapid heat dissipation to improve the compressive strength of the brake drum. The existing brake drums for automobiles cannot meet the actual needs well.
