摘要

A brake rigging (10) for a railway vehicle comprising a first (12) and a second (14) brake beam disposed on a truck bolster. A brake shoe assembly (20) disposed closely adjacent each respective end of such brake beams. A device (30) for securing a brake shoe (16) on the brake shoe assembly. A first (40) and a second (50) force transfer mechanism pivotally connected at a predetermined point disposed intermediate a first end and a radially opposed second end thereof respectively to the first and to the second brake beam for transferring a force applied thereto in order to move a brake shoe carried by a respective brake shoe assembly into frictional engagement with such respective confronting wheel of a wheel and axle set during a brake application. A first force transmitting device (60) engageable with such second brake beam for effecting rotation of such second force transfer means. An adjustable length second force transmitting device (70) having one end thereof connected to a second end of said first force transfer means and another end thereof connected to said second force transfer means and an apparatus (80) engageable with such adjustable length second force transmitting device and a predetermined portion of such brake rigging for effecting a change in a length of the adjustable length second force transmitting device as necessary due to at least one of wear and loss of brake shoes.
