Title:
RAILROAD VEHICLE BODY STRUCTURE HAVING SHOCK ABSORBING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/161610
Kind Code:
A1
Abstract:
Provided are a railroad vehicle having a shock absorbing structure such that much energy can be reliably absorbed in a small space, a vehicle body structure, and a shock absorbing structure. The shock absorbing structure is constituted by forming an end portion frame (50) of a metal member with energy absorbing members (110A) disposed in a discrete manner with respect to a longitudinal direction, the end portion frame (50) extending along the peripheral edge of a gable body structure (5) at the end of a side body structure (4), a roof body structure (3), and an underframe (2), and by joining the end portion frame (50) and the gable body structure (5) via the energy absorbing members (110A) using a fastening part (120). In this way, the end portion frame (50) at a vehicle body structure end portion can be provided with the function of constituting the vehicle body structure end portion and the function of absorbing collision energy, so that the space for the shock absorbing structure can be decreased. Simultaneously, because the energy absorbing members (110A) are disposed in a planar manner along the peripheral edge of the gable body structure (5), collision energy can be reliably absorbed without the energy absorbing members (110A) totally buckling.
