Abstract
The present invention includes a braking system for a railway car generally including a brake cylinder having a cylinder rod. The cylinder rod is in mechanical communication with a lever transfer assembly and is configured to articulate said lever transfer assembly. The lever transfer assembly may be rotatably connected to a first brake assembly and connected to a rear brake assembly through respective connection rods. Actuating the lever transfer assembly with the cylinder rod generates a divergent braking force between the first and second brake assemblies for slowing and/or stopping the railway car.
Claims21
A braking system for a railway car, the braking system defining a longitudinal centerline and comprising:
- a. a first brake assembly and a second brake assembly spaced from one another along the longitudinal centerline;
- b. a pair of live levers each defining a first end and disposed opposite the longitudinal centerline from one another, the live levers rotatably connected to the second brake assembly and connected to the first brake assembly through respective connection rods, wherein each of the live levers are rotatably connected to the second brake assembly at a fixed distance from one another;
- and
- c. a brake cylinder including a cylinder rod, the cylinder rod in mechanical communication with the first end of each live lever for articulating each live lever and moving the first and second brake assemblies away from one another along the longitudinal centerline.
A braking system for a railway car, the braking system defining a longitudinal centerline and comprising:
- a. a first brake assembly and a second brake assembly spaced from one another along the longitudinal centerline;
- b. a first live lever and a second live lever, the first and second live levers connected to the first brake assembly using respective connection rods and rotatably connected to the second brake assembly at respective connection points, wherein each of the live levers are rotatably connected to the second brake assembly at a fixed distance from one another;
- and
- c. a brake cylinder in mechanical communication with the first and second live levers for articulating the first and second live levers about their respective connection points and moving the first brake assembly away from the second brake assembly along the longitudinal centerline using the respective connection rods.
A braking system for a railway car, the braking system defining a longitudinal centerline and comprising:
- a. a first brake assembly and a second brake assembly spaced from one another along the longitudinal centerline;
- b. a lever transfer assembly rotatably connected to the second brake assembly and connected to the first brake assembly through a pair of connection rods, the lever transfer assembly substantially symmetric about the longitudinal centerline, wherein the lever transfer assembly comprises a pair of opposing live levers rotatably connected to the second brake assembly, and wherein each of pair of opposing live levers are rotatably connected to the second brake assembly at a fixed distance from one another;
- and
- c. a brake cylinder in mechanical communication with the lever transfer assembly along the longitudinal centerline for actuating the lever transfer assembly and moving the first brake assembly away from the second brake assembly along the longitudinal centerline.
