    摘要： A friction/elastomeric pad draft gear to cushion and absorb impacting forces on a railroad car coupler system. The friction/elastomeric pad draft gear includes a housing with a closed end and an open opposite end with a major axis extending therebetween. The open opposite end is provided with inwardly tapered extended internal friction surfaces. A wedge is mounted for axial movement in the open end of said housing and friction devices are positioned within the housing between the wedge and the extended internal friction surfaces. A spring seat is positioned adjacent the friction devices and on top of the elastomeric pad stack. The friction devices engagement with the wedge: forms a first selected angle of about 35 degrees null3 degrees; forms a second selected angle of about 2.25 degrees, null about 0.25 degrees, with the extended tapered internal friction surface; and forms a third selected angle of about 90 degrees, null4 degrees, with the spring seat, all in respect to the major axis.
