Braking system for a railway car
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.
Brake assembly and method for operation of said assembly
Various systems and methods for braking a vehicle are provided. In one embodiment, a brake assembly is provided that includes a lever attachment interface pivotally coupled with two degrees of freedom to a joint between a first lever and a second lever and a brake cylinder coupled to the first lever and designed to engage and disengage a brake lining in a brake component. The brake cylinder includes a slack adjuster configured to adjust a throw of the second lever.

SLIP/SKID DISCRIMINATION DEVICE, BRAKE CONTROL SYSTEM, AND SLIP/SKID DISCRIMINATION METHOD
A slip-and-skid determining device includes an axle speed decider, a reference axle speed decider, and a determiner. The axle speed decider decides, for each of a plurality of axles, an axle speed changeable based on a rotational speed of a wheel. The reference axle speed decider decides, based on the axle speed and a physical quantity changeable during travel of a railway vehicle, a reference axle speed in the vehicle. The determiner determines, based on comparison between the axle speed and the reference axle speed, whether any slip or skid of the wheel occurs.

BRAKE ASSEMBLY FOR A VEHICLE
A brake assembly for a vehicle is provided and may include a brake element. The braking element may include an arcuate body and a lobe extending from the arcuate body. The lobe may include an elongate lobe surface configured to engage a first lateral side of a tread of a wheel and not engage a second lateral side of the tread of the wheel. The brake element may further include a body surface adjacent the lobe and extending longitudinally along the arcuate body. The body surface may be configured to define a gap between the second lateral side of the tread of the wheel and the body surface to prevent engagement of the body surface with the tread of the wheel.
