Title:
RAIL VEHICLE, AND VEHICLE BODY AND END UNDERFRAME THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/114346
Kind Code:
A1
Abstract:
A rail vehicle, and a vehicle body and an end underframe thereof. The end underframe comprises a coupler end cross beam assembly (11), side beams (12, 13), a sleeper beam (14) and a force transmission beam assembly (15); the coupler end cross beam assembly (11) comprises a coupler end cross beam (111), a coupler mounting base (112) and a traction beam (113); the coupler mounting base (112) has a hollow structure, one end of the coupler mounting base (112) is fixedly connected to the side surface of the coupler end cross beam (111) facing away from the traction beam (113), and the other end of the coupler mounting base is provided with a mounting surface (1121) for mounting a coupler; the coupler end cross beam (111) is provided with a retraction through hole for enabling the coupler to pass through when the coupler is retracted in a direction from the coupler mounting base (112) towards the traction beam (113); and the traction beam (113) is provided with a retraction space (1131) for accommodating the retracted coupler. The end underframe uses an integral structure to transmit force so as to improve the resistance to compression and the capacity of heavy load bearing, and achieves the function of retracting a coupler by improving the structures of the coupler end cross beam, the traction beam and the coupler mounting base.
