Hydraulic floating caliper disc type brake device

Abstract

The invention discloses a hydraulic floating caliper disc brake device, which comprises a brake caliper and a brake disc, a first brake arm and a second brake arm are arranged on the brake caliper, the first brake arm and the second brake The boom and the brake caliper form a U-shaped structure; the first brake arm and the second brake arm are respectively located on both sides of the brake disc, and the first brake arm and the second brake arm are equipped with Friction plate for disc friction brake; the second brake arm is provided with an oil chamber, and a piston is arranged in the oil chamber; a rubber airbag is also arranged on the wall of the oil chamber, and the rubber airbag is filled with gas and located at the center of the piston. The moving axis is upward; the second brake arm is connected with the axle through the guide rod; there is also a reset mechanism between the guide rod and the second brake arm; through the structural improvement of the existing hydraulic floating caliper disc brake device, the It can have fast braking response, and can ensure that the braking device of the present invention has good braking efficiency, has simple structure, good performance, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of brakes, in particular to a hydraulic floating caliper disc brake device. Background technique [0002] A brake is a device that has the functions of slowing down, stopping or maintaining a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or slows down moving parts in machinery, commonly known as brakes and brakes. The brake is mainly composed of frame, brake parts and operating device. Some brakes are also equipped with an automatic adjustment device for the clearance of the brake parts. In order to reduce the braking torque and structural size, the brakes are usually installed on the high-speed shaft of the equipment, but large equipment with higher safety requirements should be installed near the equipment. On the low-speed shaft of the working part. [0003] At present, friction brakes are mostly used in automobiles, which use the friction between the fixed element and th...

Problems solved by technology

[0004] Caliper disc brakes can be divided into fixed caliper disc type and floating caliper disc type according to the structure of the brake caliper. The brake caliper of the hydraulic floating caliper disc brake device is floating and can move axially relative to the brake disc. , because during the braking process, the oil just needs to drive the entire brake caliper to move, which consumes a large amount of hydraulic pressure, the structure of the brake caliper is complex, the braking response is slow, and the braking efficiency is low. The hydraulic floating caliper disc brake device Difficult to adapt to the use requirements of modern cars
