A through-passage floor device

Abstract

The present invention belongs to the technical field of rail transit equipment, and specifically relates to a through-channel floor device. The main structure includes a floor support component, a corridor floor component and a ferry component, and is designed to be an ultra-thin structure to fully utilize the limited space at the bottom of a low-floor vehicle. The floor surface spans the through-channel and the vehicle body corridor. There are three rotation points at the center of the floor and the floor support component. The corridor floor bracket is made of nylon, which has both quiet and wear-resistant effects. The floor support component is provided with an angular contact spherical sliding bearing and a spherical bearing to meet the rotation, rolling, bumping and other displacement actions required by the vehicle movement. The spherical bearing installation cavity in the floor support component is installed with sealing strips on each separation surface, and two sealing strips are installed under the corridor floor cover plate, which can achieve waterproof sealing and noise-free. The structure is simple, and on the premise of meeting the line requirements, the overall height of the floor system is reduced to meet the use requirements of low-floor vehicles.
