摘要： An impact transmitting structure includes: a first member provided at an end portion of a first car; and a second member provided at an end portion of a second car. One of the first member and the second member is a convex member. The other of the first member and the second member is a concave member. An opposing surface of the convex member which surface is located close to the concave member has a substantially V shape that is convex in a direction toward the concave member. An opposing surface of the concave member which surface is located close to the convex member has a substantially V shape that is concave in a direction away from the convex member. A tip end angle of the convex member is smaller than an opening angle of the concave member.

摘要： A collision energy absorption apparatus for a rail vehicle, including a connection member, a base, and an energy-absorption splitting tube provided on the outer side in the radial direction of the connection member. The inner wall and outer wall of the energy-absorption splitting tube includes one or more pairs of slits having radial positions corresponding to each other. Each pair of slits includes an inner slit and an outer slit. Each slit is a non-closed linear slit. The slit has a width of 0.05-0.8 mm. The sum of the depths of each pair of slits is less than the wall thickness of the energy-absorption splitting tube.

摘要： A cushioning apparatus for a railway car employs a shortened yoke with a reduced-width tail for placement between stops in a conventional railway car sill. A first stack of rigid plates with elastomeric pads is provided between the straps of the modified yoke behind the coupler follower, and a second stack of plates and elastomeric pads is positioned in the sill behind the modified yoke to absorb buff loads on the coupler. In embodiments, the entire assembly may be placed in a sill having forward stops, intermediate stops, and rear stops, adapted to house a hydraulic cushioning unit.

摘要： A traction-impact device including two force transmission elements which extend along a longitudinal axis and which are connected to each other in a force-transmitting manner and an irreversible energy absorption device that includes at least one energy absorption element which at least partially or in regions, preferably completely, includes a fiber composite material. The irreversible energy absorption device is at least partially received by a first of the two force transmission elements. This first force transmission element includes a nozzle portion. The irreversible energy absorption element is arranged in such a manner with respect to the nozzle portion and the other second force transmission element that, when an impact force which exceeds the maximum permissible impact force is introduced into the traction-impact device, the irreversible energy absorption element is pressed through the nozzle portion with at least partial, preferably complete defibration of the regions formed from fiber composite material.
