Description
Technical Field
The invention relates to the technical field of magnetic suspension traffic, in particular to a railway vehicle and a railway vehicle sliding table thereof.
Background
The maglev train is a novel vehicle, has the advantages of stable and comfortable operation, low noise, strong environmental adaptability, easy control and maintenance and the like, and has formally opened high-speed and medium-low speed maglev lines in operation at home and abroad.
At present, the basic form of a running gear guide mechanism of a medium-low speed maglev train is as shown in fig. 3, and fig. 3 is a simplified structural schematic diagram of a steering mechanism in the prior art, and the main structure comprises a set of long and short T-shaped arms, two sets of steering pull rods or steel wire ropes and four steering push rods.
The steering pull rod or the steel wire rope is connected with the long and short T-shaped arms through hinged joints to form a parallelogram structure, the long and short T-shaped arms comprise rotating shafts and the like which are arranged on the underframe of the vehicle body, the long and short T-shaped arms can rotate around the rotating shafts, so that the parallelogram structure with the front rotating shafts as fixed points is formed, and the steering push rod is connected with the sliding table device of the suspension frame unit.
Two suspension frames and a set of steering mechanism are arranged in fig. 3, the two suspension frames are a first suspension frame and a second suspension frame, when a vehicle passes through a curve, the suspension module 1 and the suspension module 2 of the first suspension frame at the front end of the vehicle run along a track under the action of electromagnetic guiding force, the long T-shaped arm rotates under the action of a steering push rod, and the short T-shaped arm at the rear end of the vehicle rotates through a steering pull rod or a steel wire rope, so that the suspension module 3 and the suspension module 4 of the second suspension frame of the vehicle are driven to run in a fitting curve mode, and the vehicle smoothly passes through the curve.
When the vehicle passes through a curve, the suspension module 1 rotates by taking O1 as a center of circle, the other end P1 of the suspension module does arc motion relative to the vehicle body to P1', and the radius of the arc is the distance between O1P 1.
Taking a document with a patent number ZL201010508241.9 as an example, as shown in fig. 4, fig. 4 is a simplified moving structure diagram of a steering mechanism in the prior art, and it is mentioned that when a magnetic levitation vehicle passes through a flat curve track, a slider and a linear sliding table are displaced relatively, i.e., the steering mechanism makes a moving point P1 perform a linear motion along the x direction, as shown by a solid line in fig. 5, fig. 5 is a simplified moving structure diagram of a point P of a steering mechanism in the prior art, and a real track of the point P1 is an arc motion around a relative stationary point O1, and the track is shown by a dashed line in fig. 5.
That is, assuming that the point P1 is displaced by Δ x in the x direction, when the steering mechanism of the linear guide type is used, the point P1 reaches the point P11, and the real motion of the point P1 is an arc motion around O1, and therefore reaches the point P12. The P11 and P12 generate displacement difference delta y and rotation angle alpha in the y direction, and the displacement difference delta y and the rotation angle alpha need to be compensated in other modes, so that a train smoothly passes through a curve track.
Therefore, how to provide a railway vehicle sliding table to adapt to any length of a suspension frame and any curve radius of a line, and enable the vehicle to meet the displacement requirements of displacement and corner between the suspension frame and a vehicle body in the process of passing a curve is a technical problem to be solved urgently by technical personnel in the field at present.
