Abstract:
1. 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 assembly 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; (c) a means disposed within 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; and (d) means directly connecting said means for applying said braking force to side members of such truck portion for compensating movement of such truck portion during said braking force application and for aligning said means for applying said braking force in a predetermined position about each of said plurality of wheels.
