Suspension frame of permanent magnet maglev rail transit equipment and operation method of suspension frame
A magnetic levitation track and transportation equipment technology, which is applied in transportation and packaging, electric vehicles, railway vehicles, etc., can solve the problems that the gap between the linear motor coil and the induction plate cannot be automatically adjusted, the lateral force is large, and the wear of the guide wheel is avoided. Effects of wear, load reduction, and lateral deflection

Embodiment approach
[0052] According to an embodiment of the present invention, the guide module includes guide wheels 7 and a bogie 10, the guide wheels 7 are arranged on the four corners of the upper and lower surfaces of the magnetic levitation frame frame 20, and are connected with the bogie 10; The support module includes a support wheel 8 and a wheel support 9 adapted to the support wheel 8, and the support wheel 8 is fixed and vertically arranged on the upper frame 1 and the lower frame 2 through the wheel support 9 The side surface along the length direction is adapted to the guide wheel 7 . By adding a support module, it can work interchangeably with the guide module during the switching process of the train working state, so as to prevent the guide wheel 7 from wearing up and down vertically to the side wall.
[0053] According to one embodiment of the present invention, the driver 4 is provided with a unit for measuring the pressure change between the guide wheel 7 and the inner wall o...
Embodiment 1
[0067] use Figure 1-2 The device is also provided with a pressure sensor for measuring the pressure change between the guide wheel 7 and the inner wall of the track beam 15;
[0068] When the permanent maglev train was traveling at 100km / h, the pressure measured by the pressure sensor between the left and right guide wheels 7 on the suspension frame frame 20 and the inner sidewall of the track beam 15 was 600N; the safe range of the pressure was 400~ 800N. When the pressure on the left side guide wheel 7 exceeded 800N, the telescopic length of the left side guide wheel 7 could be adjusted by the first push rod 61, so that the left side guide wheel 7 was extended by 0.5mm each time, and the right side guide wheel 7 The amount of expansion and contraction remains unchanged until the pressure is 600N, and the adjustment is stopped; when the pressure on the right guide wheel 7 exceeds 800N, the telescopic length of the right guide wheel 7 can be adjusted through the first push r...
Embodiment 2
[0070] use Figure 1-2 The device is also provided with a pressure sensor for measuring the pressure change between the support wheel 8 and the inner wall of the track beam 15;
[0071] When the permanent maglev train stops at the station and opens the door, the first push rod 61 is used to control the supporting wheels, so that the supporting wheels 8 on the left and right sides are horizontally stretched outwards by 10 mm, and are in a state of compression with the side walls. The pressure is 600N, and then through the first push rod 61, the left and right guide wheels 7 are controlled to shrink 10mm horizontally inward, so that the guide wheels 7 do not contact the side walls, so that the support wheels 8 play a supporting role instead of the guide wheels 7; Before the permanent maglev train starts running, control the left and right guide wheels 7 to extend horizontally outward by 10mm, and put them in a state of compression with the side wall, the pressure is 600N, and th...
