7 results about "Railway brake" patented technology

A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains.

A high-temperature resistant, self-recovering railway brake pad

This invention relates to a high-temperature resistant, self-recovering railway brake pad, belonging to the technical field of railway braking devices. It includes a clamping plate, in which connecting posts are rotatably mounted within multiple equidistant circular grooves on the front side of the clamping plate. Mounting plates are fixed to the front of the connecting posts. Buffer adjustment components are provided between the mounting plates and the clamping plate. Brake pads are fitted and slidably mounted within the grooves on the front side of the mounting plates. Through the cooperation of the reset component, mounting posts, friction blocks, and brake pads, the friction blocks can automatically reset after braking. The reset spring in the reset component restores the friction blocks to their initial gap state after braking, achieving chip removal and heat dissipation. The cooperation between the buffer adjustment component and the mounting plates allows the buffer spring in the adjustment groove to buffer the mounting plate during high-speed emergency braking, preventing damage to the friction blocks due to instantaneous impact and improving the service life of the friction blocks.
