Problems solved by technology

[0002] At present, there is no unit brake device on the bogie used by railway freight cars, and the brake device mainly includes three parts, the brake machine, the foundation brake device and the hand brake, which are all installed on the car body, which limits the design space of the vehicle , especially for cars with a tight lower space such as concave bottom cars, funnel cars, and bathtub-type gondola cars, it is difficult to design. Since the brake device is installed on the car body, there are many transmission parts between the brake cylinder piston push rod and the brake shoe, which is easy Low transmission efficiency and eccentric wear of brake shoes

Abstract

A steering frame of a unit brake device is an improvement on a steering frame structure used for a truck and overcomes the defect of nonideal brake efficiency; in the steering frame of a unit brake device, a bolster and two groups of wheel pair assemblies are arranged in a side frame; a cross rod assembly is arranged in the side frame; the two ends of a spanning beam are arranged on the side frame; a lower center plate is arranged on the bolster; in the unit brake device, a brake beam is arranged in a slide slot of the side frame; a unit brake cylinder is arranged on the brake beam; a fixing pillar is suspended and set on the brake beam by a protection device; a manual brake lever is connected with the chain crane of the fixing pillar; a brake lever is connected with the fixing pillar; the brake lever is connected with the compressive brake adjuster of the chain crane; the other end of the compressive brake adjuster is connected with a lever; the lever is connected with the fixing pillar; the other end of the lever is connected with the brake cylinder push rod; the other end of the brake cylinder push rod is connected with the unit brake cylinder; a position limiter is connected with the brake lever and the compressive brake adjuster; brake shoes are arranged at the two ends of the brake beam. The steering frame of a unit brake device has the advantages of high brake efficiency and optimized car structure.

Description

Technical field: [0001] The invention is an improvement to the bogie structure used by the freight car. Background technique: [0002] At present, there is no unit brake device on the bogie used by railway freight cars, and the brake device mainly includes three parts, the brake machine, the foundation brake device and the hand brake, which are all installed on the car body, which limits the design space of the vehicle , especially for cars with a tight lower space such as concave bottom cars, funnel cars, and bathtub-type gondola cars, it is difficult to design. Since the brake device is installed on the car body, there are many transmission parts between the brake cylinder piston push rod and the brake shoe, which is easy Low transmission efficiency and eccentric wear of the brake shoe occur. Invention content: [0003] The purpose of the invention is to provide a unit brake device bogie equipped with a unit brake device, which improves the braking efficiency of the veh...
