Abstract
A railroad car draft gear is provided which includes a housing. The housing is a unitary structure, having an open end and a closed end. Compressible spring elements are located inside the housing, with an end of the spring element located against the interior side of the closed end. A friction assembly is also located within the housing, near the open end. The friction assembly provides energy absorption during compression cycles. The spring element restores the friction assembly to its fully extended position after a compression event.
