Abstract
A brake rigging for a railway vehicle having a singular truck-mounted brake apparatus for generating a braking force and a plurality of disk caliper assemblies for applying the braking force to each wheel. Wedge-like elements are rigidly attached to the braking beams of the truck-mounted brake apparatus and engage a pair of rollers that are pivotably mounted on corresponding ends of a pair of pivoted levers disposed within a disk caliper assembly. The wedge-like elements transmit a generated braking force to the levers, the rocking of which in opposite directions is effective to force the brake shoes against the respective opposite sides of a disc brake rotor to exert the braking force thereon.
Claims9
A brake rigging engageable with a truck portion of a railway vehicle, said brake rigging comprising:
- (a) a braking apparatus including a pair of brake beams associated with each wheel set of said railway vehicle, a pair of force-transfer levers pivotally connected to a strut member of each of said pair of brake beams and further connected to a first force-transmitting member, a brake cylinder assembly mounted on one of said pair of brake beams and associated with a first force-transfer lever, a second force-transmitting member connected to said brake cylinder at one end and connected to a second force-transfer lever at a distal end, whereby pressurization of said brake cylinder assembly enables said braking apparatus to generate a braking force;
- (b) a plurality of wedge means each attached to a respective end of each of said pair of said brake beams for transmitting said braking force, each of said plurality of wedge means includes a first force transmitting surface portion and a second force transmitting surface portion forming a predetermined angle disposed in a horizontal plane and extending outwardly from each of said pair of brake beams toward a respective one of a plurality of wheels of such truck portion;
- and
- (c) a means disposed within such truck portion of such truck portion intermediate said plurality of wedge means and each of said plurality of wheels of such railway vehicle and operable by said plurality of wedge means, upon direct engagement therewith for simultaneously applying said braking force to each of said plurality of wheels of such truck portion.
