Abstract

The invention relates to a safety device for railbound vehicle and discloses a collision resistance safety device for railbound vehicle, comprising a front cross beam, a longitudinal beam, a side longitudinal beam, a main energy absorption box and a side energy absorption box; one end of the longitudinal beam is connected with the front cross beam, and the other end is connected with the main energy absorption box; one end of the side longitudinal is connected with the front cross beam, and the other end is connected with the side energy absorption box; and the side longitudinal beam is positioned at the outside of the longitudinal beam; the front cross beam and the longitudinal beam are box-type closed beams; the connection point of the front cross beam and the longitudinal beam is provided with a welding strengthening plate; the side face of the longitudinal beam is provided with a plurality of holes. The safety device of railbound vehicle of the invention has good energy absorption performance and collision stability, reduces collision acceleration of vehicle, can protect passenger more effectively and is especially suitable for high-speed monorail.

Description

technical field [0001] The invention relates to a safety device for rail vehicles, in particular to a collision-resistant safety device applicable to high-speed trains. Background technique [0002] At present, most rail vehicles are equipped with anti-collision devices to ensure that losses can be avoided or minimized in the event of accidental collisions. The structural design and material composition of the anti-collision device are very critical to the realization of the anti-collision function. The Chinese utility model patent with publication number CN2499304 and publication date of July 10, 2002 discloses an anti-collision mechanism for maglev trains. Parked, but its energy absorption is limited, and there is no energy absorption index. [0003] The anti-collision box is an energy-absorbing anti-collision device for high-speed rail vehicles. It is usually assembled and welded by energy-absorbing boxes, longitudinal beams and beams. The energy box is then consumed, ...
