  • Publication number: 20080236440
    Abstract: The invention provides a shock absorbing structure capable of turning the function of the shock absorber on and off according to the level of shock during collision, thereby reducing the frequency of replacing shock absorbers. On a rear surface of a load operating unit 11 constituting a shock absorbing device 10A are attached a load transmitting shaft 12 and a shock absorber 13. The load transmitting shaft 12 is passed through the center of the shock absorber and is connected to a supporting unit 14 via a pin 15 that extends toward the radial direction. The rear end of the shock absorber 13 faces the supporting unit 14 with a clearance therebetween. The pin 15 has notched grooves 21 formed thereto. When small load is applied, the load is transmitted from the load operating unit 11 through the load transmitting shaft 12, the pin 15 and the supporting unit 14 to the main body, so that the load is not applied on the shock absorber 13.

  • Publication number: 20080163783
    Abstract: A car structure is provided which has the required strength against vertical load and vibration while avoiding increase in weight of the structure. At an entrance 6 of the railroad car structure 20 in which a side structure 2 is formed by a hollow member, the side structure 2 and a frame 7 are coupled via an L-shaped fitting 10. The L-shaped fitting 10 consists of a first joint part 10a which is in the form of a plate and couples a vehicle outer face plate 8 and a vehicle inner face plate 9 and a second joint part 10b which is in the form of a plate and butt welds a part of the first joint part 10a near the vehicle outer face plate 8 and the frame 7. Plate thickness of the second joint plate 10b is larger than plate thickness of the vehicle outer face plate 8. As a result, the required strength against vertical load can be ensured without increasing the plate thickness of the vehicle outer face plate 8, in other words, with little increase in weight of the structure.
