Problems solved by technology
[0002] In the design of the underframe of the car body, since the underframe needs to bear the large longitudinal compression and tensile load from the coupler, the stress at the front-end traction beam knife handle and the rear-end traction beam knife handle is too high. The usual method is to thicken the The plate thickness of the traction beam is increased to increase the longitudinal compression and tensile load capacity of the bearing coupler, but this method makes the entire traction beam heavier
It also increases the weight, manufacturing cost and manufacturing difficulty of the chassis

The invention relates to the field of rail vehicles, and provides a traction beam force transmission structure, an underframe and a rail vehicle. The structure includes a buffer beam, the upper end of which is provided with a pair of end door column mounting parts; a pair of side beams are respectively connected to the two ends of the buffer beam; Both ends are connected to the coupler mounting seat, a pair of front-end traction beam bodies are respectively inclined to the rear side of the buffer beam, and a pair of front-end traction beam bodies, coupler mounting seats and buffer beam form a triangular force transmission structure; The rear drawbeam body, the front ends of a pair of rear drawbeam bodies are connected to the coupler mounting seat; the corbel is installed between a pair of side beams, and the pair of rear drawbeam bodies are respectively connected to the corbel obliquely; the coupler installation The seat, a pair of rear-end traction beam bodies and the corbel form a triangular force transmission structure. The invention improves the ability of the traction beam to bear the compression and tensile load of the coupler without increasing the weight of the traction beam.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a traction beam force transmission structure, an underframe and a rail vehicle. Background technique [0002] In the design of the underframe of the car body, since the underframe needs to bear the large longitudinal compression and tensile load from the coupler, the stress at the front-end traction beam knife handle and the rear-end traction beam knife handle is too high. The usual method is to thicken the The plate thickness of the draw beam is used to increase the longitudinal compression and tensile load capacity of the bearing coupler, but this method results in a heavier draw beam. It also increases the weight, manufacturing cost and manufacturing difficulty of the chassis. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a force transm...
