摘要： An enclosure for a vehicle end opening formed between two side walls includes two bi-fold door assemblies each comprising inner and outer panels pivotally connected to one another and with the free edge of the outer panels in turn connected to a fixed pivot point adjacent the side of the end opening wherein, each inner panel may be folded outwardly 180.degree. about its pivoted connecting means and the thus folded assembly subsequently pivoted about its fixed pivot point 270.degree. into parallel relationship with the vehicle side wall. The pivotal connecting means joining each pair of inner and outer panels includes catch means serving to secure the assembly in both the closed position enclosing the vehicle end opening as well as in the stored position parallel with the vehicle side wall.

摘要： A lock mechanism for a railway car hinge-deck section includes a locking lever pivotally attached to a railway car and having an upper and lower wedge bar alternately engageable with a wedge plate carried by the hinge-deck section when the section is displaced to a raised or lowered position, respectively. Seat means affixed to the car restrict vertical displacement of the deck section and cooperates with mating inclined surfaces on the wedge bars and wedge plate to provide positive, tight retention of the hinge-deck section in either of its locked positions.

摘要： A wheel end assembly for a steerable rear axle of a four wheel steer motor vehicle chassis comprises a constant velocity joint drivingly interconnected with an axle shaft of the steerable rear axle, along a lateral axis defined by the axle shaft, and a wheel assembly for transmitting driving torque therebetween. A yoke has a main body portion with a central, laterally-extending pass-through for the constant velocity joint and is fixedly mounted to the chassis. The yoke has an upper and a lower ball joint arm which laterally extend towards the wheel assembly, where each ball joint arm has a ball joint passage therethrough. A knuckle for transferring steering rotation to the wheel assembly comprises a flat plate body with a central, lateral opening for the constant velocity joint to pass through and splined upper and lower ball joint pockets. The knuckle is configured to fit within lateral volume defined by the yoke main body and ball joint arms to minimize lateral packaging space needed for the wheel end assembly. Ball joints allow the knuckle to swivel relative to the yoke. An adapter has a central passage for the constant velocity joint to pass through and is fixed to the knuckle flat plate body and the wheel assembly to transmit rotation therebetween.
摘要翻译： 用于四轮转向机动车底盘的可转向后轴的车轮端组件包括沿着由所述车轴定义的横向轴线与所述可转向后轴的车轴驱动地互连的等速万向节，以及用于传递 其间的驱动扭矩。 轭具有主体部分，其具有用于等速万向节的中心的，横向延伸的贯穿件，并且固定地安装在底盘上。 轭具有朝向车轮组件横向延伸的上和下球关节臂，其中每个球接头臂具有穿过其中的球接头通道。 用于将转向转向传递到车轮组件的转向节包括平板体，其具有用于等速万向节的中心侧面开口，以及通过花键的上下球窝接口。 转向节配置成适合由轭主体和球形接头臂限定的横向体积，以最小化车轮端组件所需的侧向包装空间。 滚珠接头允许转向节相对于轭架转动。 适配器具有用于恒速接头穿过的中心通道，并且固定到转向节平板体和车轮组件以在其间传递旋转。

摘要： An enclosure for a vehicle end opening disposed between two side walls includes a pair of bi-fold door assemblies, each comprising inner and outer panels hingedly connected to one another with the outer edges of the innermost panel in turn hingedly connected to a hinge rod normally disposed adjacent the outer limits of the end opening. Intermediate lock means are included with each pair of door panels for selectively precluding relative displacement therebetween and when actuated allows of folding of each pair of door panels to provide a collapsed juxtaposed relationship following which the folded door assembly may be pivoted about the hinge rod 90.degree. or until parallel to the vehicle side walls. The hinge rod supporting each door assembly is in turn supported and guided by hanger and track means extending longitudinally of the vehicle whereby the folded and pivoted door assembly may be displaced in a sliding manner to a retracted or stored position within the interior of the vehicle sides, at which point locking means are actuated to retain the door assembly secured.
摘要翻译： 设置在两个侧壁之间的用于车辆端部开口的外壳包括一对双折门组件，每个双折门组件包括彼此铰接地连接的内板和外板，最内面板的外边缘依次铰链地连接到铰链杆 邻近端部开口的外部边界设置。 中间锁定装置包括在每对门板中，用于选择性地排除它们之间的相对位移，并且当被致动时允许折叠每对门板以提供折叠的并置关系，之后折叠的门组件可围绕铰链杆90°枢转 或直到平行于车辆侧壁。 支撑每个门组件的铰链杆又由支架和由车辆纵向延伸的履带装置支撑和引导，由此折叠和枢转的门组件可以以滑动方式移动到车辆侧面内部的缩回或存放位置 此时锁定装置被致动以保持门组件的固定。
