Problems solved by technology

[0003] The rotating element in the friction pair of drum brakes is the brake drum, and its working surface is a cylindrical surface. In order to make the braking effect more obvious, the brake drum generally has a larger diameter, which ensures that the friction plate on the brake shoe is in contact with the brake pad. The moving drum has a sufficient contact area, resulting in an uncompact structure of the drum brake; in addition, the drum brake works on a single acting surface
[0004] The rotating element of the disc brake is a rotating brake disc, with the end face as the working surface. In order to make the braking effect more significant, the general brake disc has a larger diameter, which ensures that the friction plate on the brake caliper and the brake The disc has sufficient contact area, resulting in a disc brake that is not compact

Embodiment 1

[0035]The compact disc brake starts the brake motor 2, the brake motor 2 drives the gear one 20 to rotate counterclockwise, the gear one 20 drives the gear two 30 to rotate clockwise, the brake shaft 3 rotates clockwise with the gear two 30, and the The left-handed screw 31 provided on the left section of the moving shaft 3 and the right-handed screw 32 provided on the right section rotate around the left support 13 and the right support 14 together with the brake shaft 3, because the left-handed screw female sleeve 4 is connected with the left-handed screw mandrel 31 through a helical pair, and the said right-handed screw mandrel 5 is connected with the right-handed screw mandrel 32 through a helical pair, so under the action of the left-handed screw mandrel 31, the left-handed screw mandrel 4 moves to the right. Under the action of the screw rod 32, the right-hand screw female sleeve 5 moves to the left, because the brake caliper 8 is provided with a V-shaped block 81 on the ...

Embodiment 2

[0037] On the basis of Embodiment 1, the first brake shoe 6 and the second brake shoe 7 are symmetrically arranged to ensure that the braking force is symmetrical and the braking effect is stable and reliable; the lower end of the first brake shoe 6 is horizontally provided with a reset seat 60 , the reset seat 60 is provided with a cylindrical slot 60-1, and the lower end of the brake shoe 7 is provided with a reset rod 70 horizontally, and the reset rod 70 is provided with a cylinder 70-1, and the cylinder 70-1 is embedded In the cylinder slot 60-1, under the action of the cylinder slot 60-1 constraining the cylinder 70-1, and under the action of the elastic restoring force of the reset rod 70, the first brake shoe 6 and the second brake shoe 7 are The hoof opening action has a pre-tension, and the contact brake effect responds quickly; the brake caliper 8 is provided with three installation holes 80, and the bolts pass through the installation holes 80 to fasten the first br...

Embodiment 3

[0039] On the basis of embodiment 1, when designing and processing the V-shaped groove 90 on the outer edge of the brake disc 9, the included angle of the V-shaped groove 90 is changed to realize the change of the braking force, as Figure 5 As shown, Fn=Fsina, with the increase of angle a, Fn increases, that is, the positive pressure increases, the braking force increases, and the change of the braking force is realized.

Abstract

The invention discloses a compact disk brake. The compact disk brake comprises a hub frame, a brake motor, a brake shaft, a left rotating nut sleeve, a right rotating nut sleeve, a first brake shoe, asecond brake shoe, brake calipers, a brake disk and a cushion plate; the hub frame is provided with a left supporting base and a right supporting base; the brake motor is connected with the hub frame; an output shaft of the brake motor is provided with a first gear; the two ends of the brake shaft are rotationally connected with the left supporting base and the right supporting base correspondingly; the middle of the brake shaft is provided with a second gear which is engaged with the first gear; the left segment of the brake shaft is provided with a left rotating lead screw, and the right segment of the brake shaft is provided with a right rotating lead screw; the left rotating nut sleeve is connected with the left rotating lead screw, and the right rotating nut sleeve is connected withthe right rotating lead screw; the cushion plate is connected with the hub frame; the upper end of the first brake shoe is hinged to the left rotating nut sleeve, and the lower end of the first brakeshoe is hinged to the cushion plate; the upper end of the second brake shoe is hinged to the right rotating nut sleeve, and the lower end of the second brake shoe is hinged to the cushion plate; the brake calipers are installed on the middle portions of the first brake shoe and the second brake shoe, so that the diameter of the brake disk can be designed small, and the integral structure is compact; and besides changing of the brake force is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile brake system, in particular, the invention relates to a compact disc brake. Background technique [0002] Automobile brakes are the braking devices of automobiles. The brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. [0003] The rotating element in the friction pair of drum brakes is the brake drum, and its working surface is a cylindrical surface. In order to make the braking effect more obvious, the brake drum generally has a larger diameter, which ensures that the friction plate on the brake shoe is in contact with the brake pad. The moving drum has a sufficient contact area, resulting in an uncompact structure of the drum brake; in addition, the drum brake works on a single acting surface. [0004] The rotating element of the disc brake is a rotating brake disc, with the end face as the working surface. In order to...
