Abstract:
A selective cushioning apparatus for a railway car absorbs draft and buff loads applied to a coupler of a railway car during train assembly and normal operation. The apparatus according to the invention provides better cushioning than a conventional draft gear without the excessive travel and maintenance issues of a hydraulic cushioning unit. In embodiments, the selective cushioning unit is adapted to fit into an AAR standard pocket for a hydraulic cushioning unit.

Claim (Index 1):
An end-of-car cushioning apparatus for a railway car, comprising:\n a yoke having a length, a front end, and a rear end opposite the front end, and having aligned apertures at the front end adapted to receive a pin or key for attaching the yoke to a railway car coupler, and having a vertical wall at the rear end; a coupler-receiving member adapted to receive buff force from the coupler and adapted to move inside the yoke; a first stack of elastomeric units positioned between the coupler-receiving member and the vertical wall of the yoke, wherein said first stack of elastomeric units is compressed in response to buff and draft loads on the coupler; a second stack of elastomeric units positioned behind the vertical wall of the yoke, wherein said second stack of elastomeric units is compressed in response to buff loads on the coupler; wherein, the maximum force transmitted to a coupler with the cushioning apparatus during impact at a speed below 6 mph is 1.5 times the weight of the impact car; wherein the maximum force transmitted to a coupler at a speed of 10 mph is 4.0 times the weight of the impact car; and wherein the maximum force transmitted to a coupler (in klbs) at a speed between 6 mph and 10 mph is defined by a line having slope 0.625.
