[0008] In view of the above technical deficiencies, in order to better solve the existing medium and low speed maglev track, suspension and driving mechanism: 1. Due to the oblique retreat of the edge of the F-shaped steel with an inclination angle, the axial force is large during rolling, resulting in serious wear of the roll pass 1. Technical problems such as low production output of each pair of rolls, low overall production efficiency, high energy consumption, and difficulty in controlling the precision of F-shaped steel; 2. The distance between the aluminum induction plate and the installation wing plate of the F-shaped steel track of the existing medium and low-speed maglev trains is smal

Abstract
The invention belongs to the field of rail traffic and relates to a U-shaped rail double-safety running and levitation driving energy-saving mechanism which is suitable for low-medium-speed maglev train double-safety running and levitation driving energy saving. The mechanism is composed of a U-shaped rail 1, a self-locking hydraulic traveling wheel mechanism 2, a connecting frame 3, a train body 4, an air spring 5, a bogie arm 6, a spindle 7, an aluminum sensing plate 8 and levitation magnets 9. By designing a U-shaped rail structure, production efficiency of the U-shaped rail is improved, roller consumption in hot rolling production is reduced, and production cost is lowered. By combining the U-shaped rail structure with the self-locking hydraulic traveling wheel mechanism, a maglev train is enabled to have a magnetic levitation and rubber wheel double-safety running mechanism, levitation-starting energy consumption of the maglev train is reduced remarkably, traction levitation energy consumption is reduced by 10-15%, and energy-saving effect is obvious. Running safety and accident emergency response capability are improved remarkably, and when a full-levitation system is in a failure, driven by a linear motor, a rubber wheel supporting train still can safely get to a target station.
Description
technical field [0001] The invention relates to a U-shaped track double-standby safe operation and suspension drive energy-saving mechanism, which belongs to the field of rail transportation and is suitable for double-standby safe operation and suspension drive energy-saving of medium and low-speed maglev trains. Background technique [0002] The theory of maglev trains was proposed by scientists in the United States and Germany in the early 20th century. After more than 90 years of continuous research in the United States, Germany, Japan, South Korea, China and other countries, the core technology of medium and low-speed maglev transportation technology has matured. Since the early 1980s, my country has started research on medium and low-speed maglev trains, focusing on the vehicle and its suspension control system. Countries around the world have also done some research on the track, but relatively few studies have been done on the details of the track, and there is even l...
