Problems solved by technology
[0004] 2) It cannot be compensated by the height control device, causing difficulties in the arrangement of the height control device
[0005] 3) Due to the inconsistency of height changes between points, the force of the shape-forming mechanism is inconsistent, which increases the pressure of suspension control
[0006] 4) Reduced the stability of the vehicle during operation
[0013] In the case of uneven load and line changes, the dynamic anti-roll beam structure of medium and low-speed maglev trains may form four points that are not coplanar, and the rolling along the diagonal cannot be controlled; the height control structure of two points and one line of high-speed maglev trains cannot control For rolling along the central axis, an additional compartment anti-roll mechanism must be added

Embodiment Construction
[0034] The principle of the air suspension height control device for maglev train proposed according to the present invention is as follows: figure 2 , 3 As shown, the device consists of two swing rods (8, 8a), a rotating rod (7), 4 rod end hinge points (9, 9a, 9b, 9c), a rotating rod crossing support (10), two A swing rod support (11, 11a), a torsion spring (5). The two swing rod supports (11, 11a) are fixed at two points A and B of a support surface (2) (such as two units of the bogie) of the air suspension, and the rotating rod hinge support (10) is fixed on the carriage At the point C of the bottom surface (3), when the relative distance of the two surfaces changes, since L is constant, the rotating rod (7) will rotate around C, which causes the rods (8, 8a) to swing, (the solid line and Dotted lines respectively represent the position of the bar before and after the relative distance of the two surfaces (2, 3) changes), and then promote the height sensor (4) to give an...

A height controller for the air suspension of magnetic hovertrain is composed of height sensors, air springs and a three-rod structure consisting of two swinging rods and one rotary rod. One end of each swinging rod is pivoted to rotary rod and its another end is pivoted to one of two fixing points on a reference plane. The middle point of rotary rod is pivoted to another reference plane. Said sensors are arranged at ends of swinging rods and rotary rod for picking up the height signals in different directions.
Description
technical field [0001] The invention relates to a device for a normally conducting maglev train, in particular to a height control device for an air suspension of a maglev train. Background technique [0002] When the maglev train travels along the track, the electromagnet must track the track. The electromagnets on both sides of the shape mechanism are in the form of a straight line, forming a parallelogram on the straight track, a sector on the curve, and a deflection surface on the transition curve. Therefore, the contouring mechanism must have a certain degree of freedom, which determines the ability of the maglev train to pass through curves and transition curves, and also directly determines the mechanical decoupling characteristics of the train. Since the bottom surface of the carriage is a rigid plane, the deflection change of the shape mechanism makes the relative height between it and the bottom surface of the carriage constantly change during the operation of the ...
