RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/037854
Kind Code:
A1
Abstract:
Provided is railway vehicle whereby travel by a first end beam towards a second end beam is permitted if an intended load has been applied. This railway vehicle (1) comprises a fuse member (F) that couples the first end beam (22) and the second end beam (23), along the vehicle longitudinal direction. The fuse member (F) is formed as a channel material (50) having a substantially U-shaped cross-section and comprising a web (50a) extending along the vehicle longitudinal direction and a pair of flanges (50b) standing upright from both end sections of the web (50a). As a result, the fuse member (F) buckles when a load received during impact exceeds a prescribed value, travel by the first end beam (22) towards the second end beam (23) is permitted, and, consequently, variation in loads that permit travel by the first end beam (22) towards the second end beam (23) can be suppressed. As a result, travel by the first end beam (22) towards the second end beam (23) can be permitted when an intended load is applied.
