Description

Forced centering suspension frame and track of maglev train

technical field

The utility model belongs to the technical field of conventional maglev trains.

Background technique

Compared with wheel-rail trains, maglev trains have significant features such as safety, economy, quietness, and environmental protection. Among them, the construction cost per kilometer and operation and maintenance cost of medium and low-speed maglev trains are lower than those of subways and light rails. At present, there is already a commercial operation line of maglev trains in Changsha, Beijing will also open a maglev train operation line, Chengdu and other places are also planning low-speed maglev train operation lines.

Wheel-rail trains have an automatic centering function because the wheel treads are tapered. When the wheels are swayed to one side due to track irregularities, they will automatically center the track under the weight of the car. The current maglev trains have no lateral force in the horizontal plane, no restoring force, and no automatic centering function. The medium and low-speed constant conduction maglev trains used on the F track have a weak centering function but cannot be adjusted in size. See the patent "F track of the maglev train" and Suspension Structure (CN201320278221)" and the paper "Research and Analysis on the Running Mechanism of a New Type of Medium and Low Speed Maglev Train with a Speed of 140km/h".

Tilt the maglev track so that the levitation force is no longer vertically upward to generate a lateral component, and adjust the lateral force of the levitation force on both sides in real time to control the suspension frame in the middle of the track.
