Problems solved by technology

[0003] (1) The strength is low, and the drum body is prone to fatigue and cracking, which will cause brake failure and accidents, and the longitudinal ribs have no strengthening effect on this
[0004] (2) The heat dissipation is poor, and the heat generated by braking is dissipated slowly, so that the temperature of the brake drum and the brake shoe of the car rises rapidly, which reduces the friction coefficient and affects the braking effect
[0005] (3) During use, due to the effect of heat and braking force, the automobile brake drum is easily deformed, which affects the bonding of the automobile brake shoe and the automobile brake drum, and reduces the braking effect

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 Shown, a kind of automobile brake drum with grid reinforcing rib, it comprises brake drum body 1, on the outer peripheral surface of brake drum drum body 1 is provided with grid-shaped reinforcing rib, and this grid-shaped reinforcing rib The ribs are composed of four annular reinforcing ribs 2 perpendicular to the axis of the brake drum body and twenty-four strip-shaped reinforcing ribs 3 parallel to the axis of the brake drum body.

[0016] Such as figure 2 As shown, there are four cross-sectional shapes of the ring rib 2 and the strip rib 3 constituting the grid rib, and these four shapes are semi-circular, triangular, trapezoidal and rectangular respectively. In practice, these are only four commonly used shapes, and the protection scope of the main claims of the present invention is not limited to these shapes.

Abstract

The invention discloses an automobile brake drum with latticed stiffeners, which comprises a brake drum body. The latticed stiffeners are arranged on the outer circumference surface of the brake drum body, and comprise a plurality of ring-shaped stiffeners which are perpendicular to the axes of the brake drum body and a plurality of strip stiffeners which are parallel with the axes of the brake drum body. The latticed stiffeners can obviously improve the strength of the brake drum, increase the stiffness, reduce the probabilities of the cracking and distortion of the brake drum caused by the effects of heat and brake force, maintain the good joint between a brake shoe and the brake drum, and simultaneously increase the heat radiating area of the brake drum, thereby effectively reducing the temperature of the brake drum, reducing the affect of the heat to steel rings and tyres, increasing the service lives of the brake drum, friction disks and the tyres, effectively preventing the accidents caused by the chap of the brake drum and tyre burst, and improving the driving security.

Description

technical field [0001] The invention relates to an automobile brake drum, in particular to an automobile brake drum with grid reinforcing ribs. Background technique [0002] At present, most of the automobile brake drums produced and used at home and abroad have smooth outer surfaces, and the outer surfaces of some products are provided with several longitudinal ribs parallel to the axial direction of the automobile brake drum. Drums have the following deficiencies: [0003] (1) The strength is low, and the drum body is prone to fatigue and cracking, which will cause brake failure and accidents, and the longitudinal ribs have no strengthening effect on this. [0004] (2) The heat dissipation is poor, and the heat generated by braking is dissipated slowly, so that the automobile brake drum and the automobile brake shoe heat up rapidly, which reduces the friction coefficient and affects the braking effect. [0005] (3) During use, due to the effect of heat and braking force,...
