Abstract

The invention relates to hydraulic brake pincers. The hydraulic brake pincers comprise a pincer body, a brake cylinder fixed to the pincer body, a lever assembly hinged to the pincer body through a lever pin shaft, and a brake lining assembly arranged on the pincer body. The rear end of the lever assembly is suitable for being pushed out by an output head of the brake cylinder. The front end of the lever assembly is suitable for pressing the brake lining assembly to the direction of a brake disc. One end of the pincer body is connected to an installing base assembly through a supporting pin shaft, and the other end of the pincer body is connected to a support assembly through a torque rod assembly. The installing base assembly and the support assembly are suitable for being installed at the shaft end of a vehicle through bolts. The hydraulic brake pincers are compact in structure, convenient to install, easy to maintain and capable of being completed without a special tool, and has hydraulic relieving and mechanical urgency relieving functions. The distance among disc pieces can be adjusted automatically, the adjusting precision is high, and use is safe and reliable. When faults occur, operators can carry out urgent mechanical relieving by rotating a hexagonal resetting screw rod, and normal operation of a vehicle can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle braking systems, and in particular relates to a floating hydraulic hydraulic braking device. Background technique [0002] For low-floor vehicles, not only the car body structure is different from ordinary trains, but also the braking system is different. The main reason is that the volume of the air source braking system is too large to be installed on the bottom of the vehicle. The hydraulic brake system has the advantages of small size and large torque, so it is applied on low floors. The core component of the basic brake of the hydraulic brake system is the hydraulic brake caliper. [0003] A floating hydraulic brake caliper. When braking, the screw rod of the brake cylinder moves from the inside to the outside under the elastic force of the disc spring in the cylinder to realize the braking process; The hydraulic oil is injected to make the piston and the gap adjustment mechanism comp...
