Description

A new wheel-rail high-speed train system

Technical Field

The present invention relates to rail transportation technology, in particular to a new wheel-rail high-speed train system.

Background Art

Rail transit, in which vehicles run on fixed rails, is widely adopted by humans for its outstanding advantages such as safety, reliability and economy. Wheel-rail trains and maglev trains are the two main technical forms of rail transit. Since there are still many bottlenecks in the large-scale application of maglev transportation, it has not been put into commercial use on a large scale. Wheel-rail trains use a mode in which the wheels mesh on the track, and the wheels are in direct contact with the track. They are widely used in railways, urban transportation, mines and other special occasions, and are the main mode of rail transit.

Since the invention of rail transit, the demand for operating speed has always been the main driving force for its progress. The actual operating speed of wheel-rail transit has now reached 350km/h, but it still cannot meet people's expectations. People hope that the operating speed will exceed 600km/h, or even higher, to replace medium and short-distance air transportation on a larger scale. However, due to the limitations of the traditional wheel-rail adhesive contact method, such a speed is difficult to achieve through the traditional wheel-rail method. Judging from the current research status and technical characteristics, magnetic levitation and other forms are most likely to achieve this goal, but magnetic levitation transportation is still in its infancy. Due to various technical and economic reasons, most of them are still in the laboratory research and development stage. At present, only the 30km line from Longyang Road to Pudong in Shanghai, my country can be called a truly high-speed magnetic levitation.

Therefore, how to break through the speed limit of traditional wheel-rail transportation has become an urgent problem to be solved.
