AI Technical Summary

Technical Problem

The noise and vibration problems of existing steel-wheeled trams are difficult to effectively control during operation, especially in sensitive areas such as residential areas and hospitals. The track structure of rubber-wheeled trams is complex, so a simple and effective turnout structure is needed.

Method used

A switch for rubber wheel tram was designed. The guide rail is nested through the rubber wheel track, and the pointed rail structure is adopted with elastic rotary conversion to realize the synergy between the rubber wheel and the steel wheel, ensuring the safe passage and guidance function of the vehicle.

Benefits of technology

It realizes the stable operation of rubber-wheeled tram in the switch area, reduces noise and vibration, has a simple structure and strong stability, and is suitable for urban rail transit.

Abstract

The present invention relates to a turnout for a rubber-wheeled tram, which is formed by the cross-combination of two lines, a rubber-wheeled track and a guide rail; a guide rail is nested in the rubber-wheeled track, and the two are parallel to each other and maintain a fixed interval to form a rubber-wheeled tram track; the rubber-wheeled tram track is branched from one line into two lines to form a turnout; the rubber-wheeled track includes a rubber-wheeled rail and a guide rail; the rubber-wheeled rail and the guide rail are arranged in pairs and are parallel to each other and maintain a fixed gauge to form their own tracks; the turnout is located within the range of the switch, and the fixed interval between the rubber-wheeled rail and the guide rail is eliminated and a point rail is provided after the turnout is combined; the front section of the point rail is connected to a conversion device. The structural design of the present invention is simple and reasonable, and can meet the requirements of safe passage of rubber-wheeled trams, and mainly relies on the contact between the rubber wheel and the corresponding rail to carry the locomotive and vehicle, and the contact between the steel wheel rail and the guide rail to achieve the functions of guiding the locomotive and vehicle in the turnout area or emergency avoidance.
