Embodiment 1

[0036] Such as Figure 1~4 As shown, a running mechanism of a medium-low speed maglev vehicle. The running mechanism includes suspension frames connected in sequence. A linear induction motor stator is suspended on both sides of each suspension frame. There are six suspension frames and a total of twelve linear induction motor stators. and symmetrically distributed on both sides of the running mechanism. The head and end of the running mechanism are provided with a head slide 7 and an end slide 8. Between the head slide 7 and the end slide 8, the first fixed slide 9 and the end slide 8 are sequentially distributed. An intermediate sliding platform 11, a second intermediate sliding platform 12, a third intermediate sliding platform 13 and a second fixed sliding platform 10, and six suspension frames are distributed in sequence and pinned to two adjacent sliding platforms respectively. A first forced guide mechanism 14 is provided between the head end slide table 7 and the first...

Embodiment 2

[0044] Such as Image 6 As shown, the difference between this embodiment and Embodiment 1 is that the way of connecting the four series groups to the vehicle-mounted traction inverter is as follows: all the four series groups are connected in parallel to one vehicle-mounted traction inverter, and the stators of all linear induction motors form three In the form of series four parallel, specifically, all four series groups are connected in parallel to the vehicle-mounted traction inverter 30 . All the other are identical with embodiment 1.

Embodiment 3

[0046] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the stators of the linear induction motor on each side of the running mechanism are divided into four groups as follows:

[0047] The linear induction motor stators on each side are first divided into two groups according to the order of arrangement, each group has three linear induction motor stators, and two adjacent linear induction motor stators are selected to be connected in series to form a series group, and the major groups are not connected in series. The linear induction motor stator of the group is connected in series with the non-series linear induction motor stators on the opposite side of the running mechanism to form a series group. The 12 linear induction motor stators form 6 series groups, and the 6 series groups are respectively connected to a vehicle traction inverter. Transformer. The method of connecting the 6 series groups to the vehicle-mounted traction in...

Abstract

The invention relates to a middle-low speed maglev vehicle running mechanism. The running mechanism comprises levitation frames connected in sequence. A linear induction motor stator is respectively hung on two sides of each levitation frame. The number of the levitation frames is six. The number of the linear induction motor stators is twelve, and the linear induction motor stators are symmetrically distributed on two sides of the running mechanism. The linear induction motor stators on each side of the running mechanism are divided into at least two groups. The linear induction motor statorsin each group are connected in series and are connected with a vehicle-mounted traction invertor. Compared with the prior art, the running mechanism increases terminal voltage of a single linear induction motor stator, and can improve maximum operation speed of a maglev train, and meanwhile system availability and reliability are improved, so as to ensure safe and stable operation of a train.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a running mechanism of a medium-low speed maglev vehicle. Background technique [0002] The maglev train is a major technological innovation in the field of transportation. The maglev train realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to drive the train. As a form of maglev train, medium and low-speed maglev trains have a speed of no more than 200 kilometers per hour. They have the advantages of low noise, high comfort, and good environmental protection performance, and can meet the needs of transportation within cities and short distances between cities. The medium and low-speed maglev train relies on the levitation magnet installed on the car to generate the levitation force. The stator (including iron core and winding) of the li...
