AI Technical Summary

Technical Problem

The parking handbrakes of existing railway vehicles require a large torque to activate and deactivate, which is inconvenient to operate and costly, making it difficult to achieve efficient and economical braking function.

Method used

A railway braking system was designed, comprising a braking linkage mechanism, an actuation mechanism, and a rotary actuation device. By changing the retraction and extension positions of the additional gripping component, the direction of the torque applied to the actuation mechanism is altered, simplifying the operation of the parking handbrake and reducing the required operating force.

Benefits of technology

It achieves efficient, simple and economical operation of the parking handbrake, ensuring that the brake can be easily released no matter how the user operates it, reducing the operating torque requirement and improving the convenience and economy of the braking system.

Abstract

The invention relates to a railway braking system comprising an actuation mechanism (15) and a rotary actuation device (16) configured to be manually actuated in rotation in a first direction and to actuate the actuation mechanism to place the system in a configuration with the parking handbrake clamped, and in a second direction and to actuate the actuation mechanism to place the system in a configuration with the parking handbrake released; the rotary actuation device comprising a main body (25) rotatably mobile and connected to the actuation mechanism, and an additional gripping member (30) configured to have a retracted position in which only the main body can be manually actuated in the first direction, and a deployed position in which the additional gripping member at least partially projects from the main body and both the main body and the additional gripping member can be manually actuated in the second direction.
