Embodiment Construction

[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0020] Figure 4 A is the rotation track of the blade in normal state, B is the braking state when the brake pedal is lightly stepped on, and C is the braking state when the brake pedal is stepped on heavily.

[0021] Such as figure 1 As shown, the brake of this automobile includes a brake drum 1, a brake base plate 2, a brake shoe assembly 3, several reset devices 4 and a gap self-adjusting mechanism 5, and the screw 6 holes in the brake drum 1 are connected with the brake base plate. 2 Connected by six screws 6, the brake shoe assembly 3 includes the first brake shoe group 7, the second brake shoe group 8, and the third brake shoe group 9 installed in parallel in the brake drum 1 in sequence. Group 10 of brake shoes ar...

Abstract

The invention provides an automobile brake, which belongs to the field of machinery, and comprises a brake drum, a brake bottom plate, a brake shoe assembly, a plurality of reset devices and a gap self-adjusting mechanism, wherein one surface of the brake drum is in matched connection with the brake bottom plate through a screw; the brake shoe assembly comprises a first brake shoe group, a second brake shoe group and a third brake shoe group which are sequentially installed in the brake drum side by side, each of the first brake shoe group, the second brake shoe group and the third brake shoe group comprises two symmetrically-arranged brake shoes, and two fixing rods used for positioning the lower portions of the brake shoes are arranged on the brake drum. A reset assembly is arranged on the upper portion of the first brake shoe group, the gap self-adjusting mechanism is arranged on the brake shoe assembly and controls the distance between the upper portions of the brake shoes on the two sides, and the gap self-adjusting mechanism comprises a driving device, a first rotating shaft, a second rotating shaft and three blades. The problems that the drum brake cannot effectively dissipate heat and a brake system is prone to deformation under the influence of high temperature are solved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an automobile brake. Background technique [0002] At present, there are two main types of brakes used in automobiles, one is drum brakes and the other is disc brakes. Drum brakes have the advantage of high braking force, but the relative heat dissipation capacity is relatively poor, and the braking force declines more seriously. Gradually disc brakes are used in the passenger car market, and more and more disc brakes are used. Disc brakes brake the tires by clamping the brake discs with brake calipers. It has the advantage of fast heat dissipation, but the relative braking force smaller. For heavy-duty vehicles, although the vehicle speed is generally not very high, due to the relatively large load, disc brakes are not suitable for such high-load situations, and the durability of the brake shoes is also higher than that of disc brakes. Therefore, for the development of a new drum brake...
