摘要： A hook-type coupler for attachment to an end of a railway transit vehicle for joining adjacent ends of a pair of railway transit vehicles wherein the hook-type coupler has a hook member pivotally mounted therein being pivotal between a latch position and an unlatch position and adapted to engage a second pivotally mounted hook member in a second hook-type coupler of compatible design and includes an uncoupling cam for forcibly pivoting the hook member to the unlatch position and a roller rotatably secured to the uncoupling cam to rollably engage a surface of the hook member when the uncoupling cam is activated through a partial rotation thereby pivoting such hook member to the unlatch position without significant sliding frictional engagement between the uncoupling cam and the hook member.

摘要： A vehicular coupler comprises a head for coupling to an opposed, generally identical coupling head of a vehicle for mechanically connecting two vehicles together. Such coupler includes a beam member for connecting to the underside of one of such vehicles. A housing is slideably connected to the beam member and a cushioning device is connected to the coupling head. The coupling head has a rearward extension located in the housing. Primary shear bolts or pins extend through walls of the housing and into the rearward extension of the cushioning device. Secondary shear bolts or pins extend through the beam member and into the housing. Retaining bolts are secured to the housing and have upper portions located above an upper surface of the housing. A longitudinal relief area is provided in the beam member, with the upper portions of the retaining bolts being located in the relief area. The relief area terminates at a predetermined location in the beam member to provide a ledge for engagement with and retention of the upper portions of the retaining bolts when the primary and secondary shear bolts or pins are sheared in two and the coupling head and housing are moved forwardly relative to the beam member.

摘要： An uncoupling cam is incorporated into a hook-type coupler. Couplers of this variety are typically found on railway transit vehicles, one hook-type coupler being fixed to each end of each transit vehicle. Moving two transit vehicles toward each other so that their ends come together will eventually cause their respective hook-type couplers to couple together automatically. It is in this manner that a passenger transit train is formed with each of its vehicles being mechanically linked to an adjacent vehicle. Each hook-type coupler has a pivotally mounted hook member that can be pivoted between a latch position and an unlatch position. A biasing means inside the hook-type coupler is used to keep the hook member normally biased to the latch position. The uncoupling cam features a solid body and a roller. The body of the cam has a uniform polygonal cross-section to an edge of which the roller is rotatably secured. The roller is adapted to rollably engage a surface of the hook member. Consequently, when the uncoupling cam is activated through a partial rotation, the hook member is forcibly pivoted to the unlatch position without significant sliding frictional engagement between the uncoupling cam and the hook member.
摘要翻译：一个非耦合凸轮结合在一个钩型耦合器中。这种品种的耦合器通常在铁路运输车辆上找到，一个钩形耦合器固定在每个运输车辆的每一端。将两个运输车辆朝向彼此移动，使其端部聚到一起将最终导致它们各自的钩型联轴器自动连接在一起。以这种方式，形成乘客中转列车，其每个车辆与相邻车辆机械连接。每个钩型联接器具有可枢转地安装的钩构件，其可以在闩锁位置和解锁位置之间枢转。钩型联接器内部的偏置装置用于保持钩构件正常地偏压到闩锁位置。非耦合凸轮具有固体和滚筒。凸轮的主体具有与辊可旋转地固定的边缘的均匀的多边形横截面。辊适于滚动地接合钩构件的表面。因此，当非耦合凸轮通过部分旋转而被启动时，钩构件被强制地枢转到解锁位置，而非耦合凸轮和钩构件之间没有显着的滑动摩擦接合。
