When the rail-mounted road-rail dual-purpose vehicle directly driven by the guide wheels runs on the rail, the guide wheels serve as guide wheels and driving wheels, the requirement that the vehicle runs on the rail is met, and the rubber wheels are adopted for traction when running on a road. The guide wheel direct driving type has the biggest characteristics of high track running safety and difficulty in derailing. The rubber wheel driven road-rail dual-purpose vehicle runs on the track and the road under the drive of the rubber wheels, but needs the guide wheels for guiding when being pulled on the track.
The rubber wheel driving type combined car for the highway and railway in China has the common phenomenon of serious abrasion of rubber tires, so that derailment accidents easily occur during traction operation, the problem of how to prolong the service life of the rubber tires needs to be considered during model selection of the combined car for the highway and railway is solved, the load of the rear guide wheel and the rear rubber tire driving wheel of the combined car for the highway and railway is reasonably distributed, and the rail tracking performance of the rear guide wheel and the driving performance of the rear rubber tire driving wheel are guaranteed.
The existing railway vehicles can only run on a railway or a road, cannot adapt to complex and variable conditions, and need to be switched between the road and the railway at any time. The guide wheel type is a more mode at present, but the mode has the defects of complicated load distribution of the rubber wheel and the guide wheel, serious tire wear and unstable running of the guide wheel. Derailment accidents easily occur when crossing a switch or running at high speed.
