Through passage floor system

Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to a through passage floor system mainly structurally comprising a gangway foot plate, pedals, wearing strips and connecting rods; two sides of the gangway foot plate are respectively lapped on the pedals, the lapping ends of the gangway foot plate and the pedals are discontinuously or uninterruptedly provided with the wearing strips, and the gangway foot plate is connected with the pedals through 2-3 connecting rods. The pedals are connected with a vehicle body frame through pedal supports, nylon and graphite are combined for advantage complementation by optimizing the structure of the wearing strips, the self-lubricating function is achieved, the toughness and abrasion resistance of a nylon base body and the excellent lubricating antifriction performance of the graphite are both achieved, the bearing capacity is achieved, the self-lubricating limit of the nylon is broken through, the friction coefficient of the pedals and the gangway foot plate and the noise decibel generated in the running process of the vehicle are greatly reduced, the internal environment of the vehicle during running is improved, the comfort of passengers is improved, and the service life is prolonged.

Description

Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a through-passage floor system. By optimizing the structure of a wear strip, the friction coefficient between a pedal and a crossing plate is reduced, and the service life of the floor is prolonged. Background technique: [0002] The through passage is an internal passage for passengers to freely walk from one carriage of rail transit vehicles to another carriage and make passengers feel safe and comfortable. The floor system is used at the lower part of the connection between two vehicles or carriages to carry passengers. Ensure the safe passage of passengers from the through passage area. The floor system undergoes irregular relative displacement with the operation of the vehicle. [0003] In the prior art, the cross-board of the floor system has a large load-bearing load and frequent friction with the pedal, which has the problems of noise pollutio...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the crossing plate of the floor system carries a large load and frequently rubs against the pedal, which has the problems of noise pollution and short service life.
