Title:
LOCOMOTIVE STRUCTURE OF RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/112684
Kind Code:
A1
Abstract:
Disclosed is a locomotive structure of a railway vehicle. The locomotive structure comprises a vehicle body main structure (1), a driver cab frame (2) and an anti-creeper installation structure (4), wherein the anti-creeper installation structure (4) is a double-layer box structure in a t shape, with two side ends respectively fixedly connected to an underframe edge beam (14) and a coupler installation base (11) at a corresponding side; and a driver cab floor (12) covers the anti-creeper installation structure from above. The locomotive structure possesses great longitudinal and vertical strength and stiffness, wherein a single anti-creeper installation area is capable of bearing a longitudinal compression force of 600 kN and a vertical weight of 13t. With a large longitudinal adjustment, the locomotive structure can get infinitely close to a floor surface of a vehicle body, solving the problem of matching with vehicles of existing railways; and dependency on the strength of the underframe edge beam is remarkably reduced, which favours of realizing a streamlined shape.
