Description
Technical Field
The invention relates to the technical field of magnetic suspension rail transit, in particular to an embedded permanent magnet suspension traffic suspension frame and a rail mechanical structure.
Background
The magnetic suspension train is a novel rail transit with great development prospect, the magnetic force of the rail suspends the train in the air, the friction force is reduced, the magnetic suspension train is different from a wheel-rail train in the traveling process, the magnetic suspension train needs to be in contact with the ground, and only the resistance from the air is received, so that the higher operation speed can be realized. At present, a magnetic suspension train generally generates electromagnetic force through electromagnets to provide suspension force and guiding force required by train operation, and the suspension function and the guiding function are two major difficulties faced in the suspension erection timing of the magnetic suspension train.
For a permanent magnet suspension train, when a vehicle turns, a suspension frame is subjected to the action of centrifugal force to generate large impact, and meanwhile, a lateral force generated by repulsive force suspension acts on the suspension frame to cause the vehicle body to deviate, so that the vehicle is guided through a guide wheel and the lateral force is borne through the guide wheel. However, such mechanical contact tends to impart large vibrations to the operating vehicle system; meanwhile, in the running process of the suspension type permanent magnet suspension train, the suspension frame can float up and down due to the change of the suspension force and the change of the load capacity, so that the guide wheel can be abraded in the up-down direction, and even the rubber wheel can fall off; in addition, the guide wheels can generate noise, thereby bringing certain potential safety hazard to the running of the magnetic suspension train and reducing the stability and riding comfort of a vehicle system.
The suspension bogie of the magnetic suspension train disclosed in the suspension type magnetic suspension rail transit system disclosed in the Chinese invention patent 201810884768.8 is composed of a framework, a beam, a guide wheel, a permanent magnet module and the like. When the magnetic suspension train runs, the guide wheel rolls on the inner wall of the track beam to conduct guide running. However, when the suspension bogie operates, rolling friction is generated between the guide wheels and the track beam, so that certain noise pollution is caused, and the phenomenon that the permanent magnet suspension train is laterally deviated due to repulsive force generated between the permanent magnet modules on the bogie and the permanent magnet tracks arranged in the track beam cannot be avoided.
The invention patent 201911035850.4 discloses a magnetic suspension train guiding method and a guide wheel device, which comprises a base, a rotary bearing, a wheel shaft, a spring, a linear bearing, a guide wheel and the like. In the process that the suspension frame floats up and down due to mutual repulsion between the permanent magnets, the position structure of the guide wheel of the suspension frame is adjusted by the adjusting spring, so that the effect that the guide wheel rolls in the horizontal direction and moves in the vertical direction is achieved, but the problem that the suspension frame deviates laterally when lateral force generated by the permanent magnets occurs also exists.
