Disk brake with increase tend

Abstract

The invention discloses a disc brake with increasing potential. Two thrust pistons, two brake rocker arms and brake discs are installed between the corresponding hydraulic cylinders. One end of the two thrust pistons is connected with the high-pressure oil chamber of the hydraulic cylinder, and the other end of the two thrust pistons is respectively connected to the The sides of the brake rocker arms are in contact with each other. The short sides of the two right-angle brake rocker arms are respectively equipped with friction plates. The pins are equipped with cylindrical helical torsion return springs, and the rotation of the two right-angle brake rocker arms on the respective brake rocker support pins can make the friction plates on the short sides of the two right-angle brake rocker arms pressed against the brake disc. sides of the . The invention combines the advantages of traditional disc brakes and drum brakes, so that it not only has good thermal fading performance like disc brakes, but also has high braking efficiency like drum brakes, and improves the braking performance of the brakes. and reliability.

Description

technical field [0001] The invention relates to a brake, in particular to a disc brake with increasing potential. Background technique [0002] There are two types of brakes used in automobiles: disc brakes and drum brakes. Disc brakes have a large area in contact with the air, good heat dissipation, and good thermal decay resistance, but their braking efficiency is small, that is, the brake. The braking force is small; in comparison, the drum brake will generate a torque that further presses the brake shoe on the brake drum during braking, so it has the effect of "braking momentum" and can provide high braking force , The braking efficiency is high, but on the other hand, due to the small heat dissipation area of ​​the drum brake, the heat generated during the braking process cannot be discharged in time, which will greatly reduce the braking force, that is, the thermal fading resistance is poor. Contents of the invention [0003] In order to overcome the poor thermal fa...
