Abstract

The invention provides an underframe structure and a train having the same. The underframe structure includes corbels, traction beams, inner longitudinal beams and inner side beams. The corbels are arranged transversely along the underframe structure; the traction beam is set at the front end of the corbels and arranged longitudinally along the underframe structure; The longitudinal beam is set at the rear end of the corbel and along the longitudinal direction of the chassis structure. The inner side beams are arranged on both sides of the pillow beam and arranged longitudinally along the chassis structure; among them, the strength of the traction beam, the pillow beam and the pillow inner longitudinal beam decreases in sequence from the front end to the rear end of the chassis structure to reduce the The traction force acting on the traction beam is transmitted to the inner edge beam. In this way, the traction force from the bogie is evenly distributed to achieve the overall load-bearing of the vehicle body. This solves the problem that the train chassis in the prior art cannot transmit the traction force of the bogie evenly.

Description

technical field [0001] The invention relates to the field of train equipment, in particular to an underframe structure and a train with the same. Background technique [0002] The underframe of the train is used to carry the traction force of the body and the bogie. Existing train underframe is generally welded by drawing beam, corbel and each longitudinal beam etc. Due to structural design problems, the existing underframe cannot evenly transmit the traction force from the bogie to the inner edge beams on both sides. Thereby there is the problem that the bearing capacity is small and the structural strength is not high. Contents of the invention [0003] The main purpose of the present invention is to provide an underframe structure and a train having the same, so as to solve the problem that the underframe of the train in the prior art cannot evenly transmit the traction force of the bogie. [0004] In order to achieve the above object, according to the first aspect o...
