摘要： A draft gear assembly is disclosed alone and in combination with a draft sill and a coupler. The draft sill has front and rear stops defining a draft gear pocket. The draft gear assembly has a yoke, a coupler follower, a rear follower, a front resilient member and a back resilient member. The yoke has top and bottom stops. The coupler follower is biased against the yoke top and bottom stops. The draft gear assembly also includes a center rod that extends through the yoke, through the back resilient member and through the rear follower. Prior to installation on a railcar, there is a shortening member on the center rod. The length of the assembly between the shortening member and the front of the coupler follower is slightly less than the longitudinal length of the draft gear pocket. After installation, the rear follower is positioned against rear stops of the draft sill. After installation, the yoke, coupler and coupler follower each have a neutral position and a full buff position. The yoke and coupler also have a full draft position. The draft stroke of the coupler and yoke is 1¼ inches forward. The buff stroke of the coupler and coupler follower is at least 4¼ inches rearward, while the buff stroke of the yoke is 3 inches rearward. The center rod is free from compression throughout buff movement and free from tension throughout draft movement of the coupler and yoke.

摘要翻译： 牵引齿轮组件单独公开，并与起落梁和联接器组合。 通风门具有前挡块和后挡块，限定了一个牵引齿轮箱。 牵引齿轮组件具有轭，耦合器从动件，后从动件，前弹性构件和后弹性构件。 轭具有顶部和底部止挡。 联结器随动件被偏压抵靠轭顶部和底部止动件。 牵引齿轮组件还包括中心杆，其延伸穿过轭，穿过后弹性构件并通过后跟随器。 在轨道车辆上安装之前，中心杆上有一个缩短构件。 缩短构件和联接器从动件的前部之间的组件的长度略小于牵引齿轮槽的纵向长度。 安装后，后跟随器位于挡板的后挡块上。 安装后，磁轭，联轴器和联轴器跟随器各有一个中立位置和一个满凸轮位置。 轭和耦合器也具有完整的吃水位置。 联轴器和轭的牵引冲程为1¼英寸向前。 耦合器和耦合器跟随器的抛光笔冲向后至少4¼英寸，而轭的抛光笔冲向后3英寸。 中心杆在整个抛光机运动时没有压缩，在联轴器和轭架的牵引运动中没有张力。

摘要： A slackless drawbar assembly joining railcars includes a drawbar, each end of the drawbar being joined to a yoke surrounding a cushioning unit and a follower block confined between forward and rear stops in a conventional sill pocket. The cushioning unit includes a front plate, an elongate spacer block and a compressed stack of elastomer pads sandwiched between the plate and block. Tightening wedges and shims are not used. The compressed pad stock holds the cushioning unit between the stops with a preload of about 50,000 pounds to prevent binding between the drawbar and the follower plate from causing derailments. The preload also holds the cushioning unit tight in the pocket.
