Abstract

The invention relates to a rigid following mechanism and a brake clamp unit for a variable-gauge bogie. The rigid following mechanism comprises a following connecting part, a positioning device and atleast two fixed parts, wherein the positioning device is mounted on the following connecting part; and the fixed parts are parallel to each other. The following connecting part and the fixed parts are installed in a sliding fit mode. The positioning device is connected with a first fixed part in a contact mode. Contact sliding parts are separately installed on two supporting arms of the followingconnecting part. The brake clamp unit comprises a mounting bracket and a brake actuator and a rigid follower mechanism, wherein the brake actuator is mounted on the mounting bracket. The following connecting part and the brake actuator are installed in a fit mode. The positioning device is tightly attached to the mounting bracket, and the fixed parts are fixedly installed on the mounting bracket.The rigid following mechanism and the brake clamp unit for the variable-gauge bogie can change the position along with wheels, the position on a target gauge position is automatically found, and thechange of the position is achieved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle braking, and relates to a rail vehicle braking device, in particular to a rigid follower mechanism and a brake caliper unit for a variable-gauge bogie. Background technique [0002] In the basic braking device in the field of rail transit, the disc brake device is generally called a brake caliper unit, and the brake caliper unit mainly includes two structures, namely a three-point mounting structure and a compact four-point mounting structure. The above-mentioned brake caliper unit structures have a common feature, they are all fixed at the hoisting position. After the brake caliper unit is installed, it is fixed relative to the bogie. This kind of brake caliper unit has been widely used at home and abroad. There is basically no change in the relative displacement of the clamp unit and the brake disc. [0003] With the development of the internationalization of the world and the development ...
