Abstract

The invention discloses a bridge component and a bridge system of a rail vehicle. The bridge assembly includes: pier column and track beam, the lower end of the pier column is connected to the base; the track beam includes two guide rail beams, each guide rail beam includes a fixed plate, a flange plate and an intermediate guide assembly, and the fixed plate is supported on the pier column On the upper end face, the flange plate is arranged above the fixed plate, the traveling wheels run on the upper surface of the flange plate, and the middle guide assembly is suitable for contacting and cooperating with the guide wheels to guide the running track of the guide wheels. In the bridge assembly of the present invention, the two guide rail beams of the track beam are firmly supported on the base through piers, so that the rail vehicle can run smoothly on the bridge assembly, and by making the guide wheels of the rail vehicle and the middle guide The contact and fit of the components prevents the track of the rail vehicle from shifting during driving, further improving the stability of the road vehicle running on the bridge component.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a bridge assembly of a rail vehicle and a bridge system with the same. Background technique [0002] With the continuous advancement of urbanization, rail vehicles can bring a lot of convenience to life and production. However, in related technologies, due to the complex steel structure of bridge components, difficult construction, difficult quality assurance, small overload capacity, high self-weight, and high cost, the application of rail vehicles cannot be rapidly developed. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the present invention proposes a bridge assembly for a rail vehicle, which has a simple structure, good integrity and high safety, so that the rail vehicle can run on the bridge assembly smoothly. [0005] The invention also proposes a bridge system f...
