Abstract

The invention belongs to the field of railway locomotive vehicle braking technologies, and relates to a railway locomotive vehicle braking clamp unit. The clamp unit comprises a box body, a braking cylinder, a braking force multiplication mechanism, braking clamp arms, a buffering device and a brake lining gap adjustor, wherein the braking cylinder is fixedly connected with the box body, a reset taper spring is located between a cylinder cover of the braking cylinder and a diaphragm plate, an eccentric shaft and a connecting rod form an eccentric shaft type lever, the driving braking clamp arm is hinged to the eccentric shaft, the driven braking clamp arm is hinged to the box body, the force bearing end of a lever hook and the end of a connecting rod of the braking force multiplication mechanism are spaced with a certain distance, the force applying end of the lever hook is connected with a push rod, and the buffering device is located between the box body and the force bearing end of the lever hook. The transverse width of the braking clamp unit is small, the piston diameter and the multiplying power of the clamp arms are reduced, the requirement of a spring stopping braking cylinder for an energy accumulating spring is lowered, and the size of the railway locomotive vehicle braking clamp unit is reduced. The railway locomotive vehicle braking clamp unit is wide in application range, high in modularization degree and complete in function.

Description

technical field [0001] The invention belongs to the technical field of rail locomotive vehicle braking, and relates to a rail locomotive vehicle brake caliper unit, which is installed on the rail locomotive vehicle bogie and used to execute braking instructions and generate or eliminate brake pad pressure. . Background technique [0002] Brake caliper unit is an important part of rail rolling stock, generally used in high-speed rail locomotives, urban rail vehicles, ordinary railway passenger cars, high-speed EMUs and other rail rolling stock that use disc brakes to realize the safety of rail rolling stock. Air brake and parking brake. [0003] At present, the existing installation forms of the brake caliper unit mainly include: decentralized three-point hoisting and connecting frame installation, each installation form has its own unique main structure, and the modularity of the main structure is not high, and it is inconvenient to disassemble , complicated maintenance. ...
