Abstract

The invention provides a friction braking device. The friction braking device is composed of braking cylinders, hinge rods, levers, reset springs, torsional springs, floating rods, flexible blocks, brake pads and brake pad supports, wherein the braking cylinders and the levers are installed on vehicle floating plates, the braking cylinders are hinged to the levers, the levers on the two sides arehinged through the floating rods, the floating rods penetrate through the flexible blocks, the flexible blocks are fixed in the vehicle floating plates, the brake pad supports are linked on the leversthrough bolts, the torsional springs are installed between the brake pad supports and the levers, the reset springs are installed between the levers and the floating plates, and the brake pads are installed on the brake pad supports. The friction braking device is high in braking efficiency and compact in structure, and can be well suitable for braking working conditions of vehicles and complex electromagnetic environments.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle brake systems, and in particular relates to a friction brake device. Background technique [0002] The disc-shaped friction braking device used on traditional wheel-rail vehicles is only composed of a brake cylinder, a lever, a brake pad holder, and a brake pad. , so as to realize the braking or release of the vehicle. And this kind of braking device, when tightening state, the position between brake cylinder and the friction body to be tightened remains unchanged, and this has also just caused corresponding technical problem, [0003] In particular, this type of braking device cannot be applied to maglev vehicles. Unlike traditional wheel-rail vehicles, maglev trains are levitated and guided by electromagnetic force generated by electromagnetic coils, and are pulled by linear motors. The braking system mostly uses eddy currents. brakes. Eddy current braking is a non-contact braking method...
