Problems solved by technology

[0002] The lever of the existing floating single-side acting brake caliper for rail transit is only composed of a lever body. In actual work, the contact area and contact angle between one end of the lever body and the output shaft of the brake cylinder vary with the output shaft of the brake cylinder. It is changed by jacking up, which makes the efficiency of the lever to transmit the braking force low; at the same time, when there is a problem inside the clamp that needs to be alleviated, it cannot be alleviated; when working, one end of the lever body is frequently impacted by the output shaft of the brake cylinder, which is very easy to wear and tear. The entire lever needs to be replaced, greatly increasing maintenance costs

Abstract

A jack block structure for a lever mechanism of a brake caliper, which has a jack block body, and the jack block body has two coaxial connecting shafts, the connecting shafts are connected or integrated with the jack block body, and are located on the jack block body On the outer wall of the top block, there are radial positioning holes on the body of the top block, and the positioning holes are threadedly connected with the limit screws. There is a mounting hole on the top block body, and a fixed screw plug is installed in the mounting hole. A circumferential limit groove is opened on the outer peripheral wall of the fixed screw plug. There is a pressure block in the counterbore. After the brake caliper lever mechanism uses this top block structure, the pressure block of the top block structure can always maintain the largest area of ​​contact with the output shaft of the brake cylinder, which effectively improves the efficiency of braking force transmission. When a failure occurs, just Manual relief can be achieved by adjusting the fixed screw plug in the top block structure, which is easy to operate. When the pressure block is worn out, only the pressure block needs to be replaced, and the maintenance cost is low.

Description

technical field [0001] The invention belongs to the technical field of foundation braking devices, and in particular relates to a top block structure used for a rail transit brake caliper lever mechanism. Background technique [0002] The lever of the existing floating single-side acting brake caliper for rail transit is only composed of a lever body. In actual work, the contact area and contact angle between one end of the lever body and the output shaft of the brake cylinder vary with the output shaft of the brake cylinder. It is changed by jacking up, which makes the efficiency of the lever to transmit the braking force low; at the same time, when there is a problem inside the clamp that needs to be alleviated, it cannot be alleviated; when working, one end of the lever body is frequently impacted by the output shaft of the brake cylinder, which is very easy to wear and tear. The entire lever needs to be replaced, greatly increasing maintenance costs. Contents of the in...
