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： A collision attenuating system for a moving vehicle including an energy-absorbing airbag assembly dimensioned and configured for attenuating the impact between the moving vehicle and a pedestrian or an impacted vehicle located in or crossing the path of the moving vehicle as the pedestrian or impacted vehicle impacts against the airbag assembly, a mounting bracket dimensioned and configured for being affixed to the moving vehicle, an engagement bracket affixed to the airbag assembly and engagable with the mounting bracket, and a quick-release fastener for removably engaging the engagement bracket to the mounting bracket for removably mounting the airbag assembly to the moving vehicle. The airbag assembly includes an airbag and an assembly frame supporting the airbag, a speed sensor for determining the speed of the vehicle, and a pressure regulator for controlling a pressure function of the airbag responsive to the speed sensor. The airbag assembly includes an upper deflatable airbag, and a lower pedestrian support, the pedestrian support including energy-absorbing structure. A method of using the collision attenuating system is also described.

摘要： A railcar draft gear housing formed from an austempered ductile iron casting having an original shape and including an open end, a closed end, and wall structure axially extending between the housing's ends. The wall structure of the housing defines an axial section between and spaced from the ends. The axial section of the wall structure is configured to withstand impact energy imparted to the housing in excess of 81,000 inch pounds while retaining and exhibiting substantially linear elasticity wherein the resultant ratio of stress to energy input remains substantially constant thereby allowing for flexible distortion of the housing in a manner promoting enhanced energy damping characteristics while allowing the casting to return to the original shape after the impact energy is released threrefrom.
摘要翻译：轨道牵引齿轮壳体由具有原始形状的奥氏体球墨铸铁铸件形成并且包括在壳体的端部之间轴向延伸的开口端，封闭端和壁结构。壳体的壁结构限定了在两端之间和间隔开的轴向部分。壁结构的轴向部分构造成承受超过81,000英寸磅的施加到壳体的冲击能量，同时保持并呈现基本上线性的弹性，其中应力与能量输入的合成比保持基本上恒定，从而允许壳体的柔性变形以促进增强的能量阻尼特性的方式，同时允许铸造在冲击能量被释放之后恢复到原始形状。

摘要： The gas-hydraulic shock absorber assembly comprises a sleeve member and a ram member movable relative to the sleeve member. In the interior of the ram member, a gas chamber is provided that is pressurized by means of a gas. In the interior of the sleeve member, an oil chamber is provided that is filled with a hydraulic medium and which decreases in volume the more the ram member is moved relative to the sleeve member. Between the two chambers, a gas-hydraulic control assembly is provided. Upstream of the control assembly, there is a bleeding assembly, comprising a transfer channel opening into a portion of the oil chamber remote from the control assembly. Further provided is a bleeding channel, opening into an upper portion of the oil chamber and connecting the transfer channel to the control assembly when the shock absorber assembly is at rest. The bleeding assembly comprises several channels connecting the oil chamber to the control assembly and comprising each a V-shaped valve flap to close the channels. Even if the ram member is moved slowly relative to the sleeve member, any gas collected in the oil chamber can escape through the transfer channel and/or the bleeding channel. At high relative moving velocities, the two legs of the valve flaps are moved towards each other such that the oil can flow through the channels of the bleeding assembly, whereby the collected gas can escape through the transfer channel and the bleeding channel.
摘要翻译：气体液压减震器组件包括套筒构件和可相对于套筒构件移动的柱塞构件。在冲头构件的内部，设有通过气体加压的气室。在套筒构件的内部，设置有油室，其充满液压介质并且体积减小，柱塞构件相对于套筒构件移动得越多。在两个室之间，设置有气液控制组件。在控制组件的上游，存在渗流组件，包括通向远离控制组件的油室的一部分的传送通道。进一步提供了一种渗透通道，当减震器组件处于静止状态时，其通向油室的上部并且将传送通道连接到控制组件。出血组件包括将油室连接到控制组件的多个通道，并且包括每个V形阀瓣以封闭通道。即使柱塞构件相对于套筒构件缓慢地移动，在油室中收集的任何气体都可以通过传送通道和/或排出通道逸出。在高相对移动速度下，阀瓣的两个腿彼此移动，使得油可以流过出血组件的通道，由此收集的气体可以通过输送通道和出血通道逸出。

摘要： A train collision attenuator mounted on a leading end of a train for attenuating the force of impact between a moving train and a pedestrian or motor vehicle. The train collision attenuator includes an energy absorbing assembly and a mounting assembly. The energy absorbing assembly includes a leading surface and the energy absorbing assembly is dimensioned and configured for attenuating the force of impact between the moving train and the pedestrian located in the path of the moving train as the pedestrian impacts against the leading surface. The mounting assembly secures the energy absorbing assembly to the leading end of the train. A lifting mechanism for moving the energy absorbing assembly between a deployed position to a retracted position is also provided. A selectively-inflatable, externally-mounted airbag including an upper pedestrian cushioning portion and a lower pedestrian support portion is also provided. An energy absorbing hydraulic cylinder and a vehicle contact plate mounted on the hydraulic cylinder piston is also provided.
