  • RAILCAR BODYSHELL
    Publication number: 20220306166
    Abstract: An object is to provide a railcar bodyshell whose deformation behavior at the time of collision is stable. The railcar bodyshell includes an anti-climber projecting from an end beam outward in a car longitudinal direction. The anti-climber includes a starting point portion that serves as a starting point of bending of the end beam when collision has occurred, and the end beam is bent by a collision load. The starting point portion is disposed at a portion corresponding to a position between a front end of an energy absorber and a corner post in a car width direction.

  • Impact transmitting structure configured to transmit impact to impact absorbing device of railcar
    Patent number: 11305793
    Abstract: 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.
