AI Technical Summary

Technical Problem

The guide rail type rubber-tired intelligent rapid transit system (RRT) cannot intersect with existing roads at level, which affects the aesthetics of the city and requires the construction of dedicated operating lines, thus limiting its market promotion.

Method used

Design an adaptive telescopic system that coordinates guide wheels and rails, including a guide frame, guide arm, telescopic rod and guide wheel. The telescopic movement of the guide wheel is achieved by interlocking with the guide rail to adapt to the height difference between the viaduct and the ground. A hydraulic damper is used to control the movement of the telescopic rod.

Benefits of technology

It enables a natural transition between elevated bridges and urban roads using the guide rail type rubber wheel system, reduces line modification costs, enhances line laying flexibility, and expands market application scenarios.
