Abstract
A brake system wherein the single actuator is freely mounted to a first brake beam so as to align its force application axis with the axis of a first force transmitting rod connected at its other end to a transfer lever on a second brake beam. A second force transmitting rod connects the transfer lever back to the first brake beam. The mounts for the actuator and the transfer lever are designed for use with brake beams of dual actuator brake systems.
Claims16
A brake system for a railway vehicle comprising:
- first and second brake beams;
- a transfer lever pivotally connected at a point intermediate the ends thereof to said second brake beam;
- first and second force transmitting means each having a second end connected to opposite arms of said transfer lever and a force transmitting axis, and a first end of said second force transmitting means being connected to said first brake beam;
- actuator means connected to a first end of said first force transmitting means for controlling the position of said first force transmitting means along a force application axis in response to fluid pressure;
- and
- mounting means freely mounting said actuator means to said first brake beam for maintaining said actuator means force application axis coaxial with said first force transmitting means transmitting axis over the full operating range of said actuator means.
A brake system according to claim. 1, including a bracket mounted to said second brake beam and having an aperture aligned with a second aperture of said second brake beam;
- said second force transmitting means extends through said apertures;
- and said transfer lever is pivotally mounted to said bracket.
A method of converting a dual actuator brake system for a railway vehicle having first and second brake beams each with an actuator aperture having mounting holes about its periphery and a force transmitting aperture having mounting holes to a single actuator brake system comprising:
- mounting an actuator with a first force transmitting means extending therefrom at said actuator aperture of said first brake beam so as to rotate about predetermined first and second orthogonal axis using said mounting holes of said actuator aperture and with said first force transmitting means extending through said force transmitting aperture in said second brake beam;
- mounting a transfer lever pivotally to said second brake beam using said mounting holes of said actuator aperture;
- connecting said first force transmitting means to an arm of said transfer lever;
- inserting a second force transmitting means to extend through said actuator aperture of said second brake beam and into said force transmitting aperture of said first brake beam;
- and
- connecting said second force transmitting means to an opposite arm of said transfer lever and to said first brake beam using said mounting holes of said force transmitting aperture.
A single actuator brake system for a railway vehicle comprising:
- first and second brake beams each with a first aperture having mounting holes about its periphery and a second aperture;
- actuator means with a first force transmitting means extending therefrom;
- means for mounting said actuator means to said first brake beam so as to pivot about predetermined first and second orthogonal axis at said first aperture of said first brake beam using said mounting holes of said first aperture and with said first force transmitting means extending through said second aperture in said second brake beam;
- transfer lever means pivotally connected to said second brake beam using said mounting holes of said first aperture of said second brake beam;
- said first force transmitting means being connected to an arm of said transfer lever means;
- and
- second force transmitting means connected to an opposite arm of said transfer lever means, extending through said first aperture of said second brake beam and connected to said first brake beam at said second aperture of said first brake beam.
