Mostly the movement is polarity and the poles are arranged relative to the conductive ™ ™. 2. Permanent magnets are mounted on the carriage and attached to the bracket .3, which by means of hinged rods 4 n 5 is attached to the strap b and has the possibility of rotational and transverse movement of the horizontal plane of the mountain top from the bracket 3 of the frame b. thinned out by means of springs 7

The frame b is sprung relative to the car body 3 by springs 9 p attached to the body 8 by articulated knobs & sh 10, making it possible to move the frame 6 to the car body 8 in the vertical direction, limiting the horizontal displacement

horizontal contours and mechanically fastened together in the bottom of the ferromagnetic core 23.

Short-circuited circuits 24 of material B1LOCA conductivity (aluminum, copper and their alloys) are electrically isolated from one another on the core 23. Co. closed circuit 24 are located in planes perpendicular to the longitudinal axis of the guide 2,

To increase the lifting force, the suspension contains permanent magnets 25 attached to the bracket 3 with S pole and tips 26. The magnets 25 have vertical magnetization and are located symmetrically with respect to the ferromagnetic plates 27. mounted in the track. 0 The vertical distance between the plates 27 is equal to the distance between the jTMCHbftK tips 26. The plates 2 are fastened to each other by brackets 28f and to the track 29 5 there is a scrap of pads 30,.

Refueling to tsa 2 is attached to a non-magnetic metal beam 3t, which is mounted on plates 27 and attached to the track 29. g Hs circuits to dich 2 with a certain step along the path length are mounted inductors 32 of a linear induction motor

And the girder 31 is finishing, which provides instant mechanical friction and wear when interfacing-E nh with skeleunalchi 12, Stable) ovanna5g magnetic poddeska works sweet-g model. The vertical lifting force in the far suspension due to the magnetic shear forces when the wick of the magnets 1 relative to the core 23 and the magneto 25 with the pole and ends 26 relative to the ferromagnetic plate 27 is excluded. It is assumed that most of the lifting force is generated by the magnets 25.

This suspension does not require any TopOB peryjj in order to be stable in the vertical direction. However, when the carriage is stationary, the suspension is unstable in the transverse {(horizontal) direction, i.e. the magnets tend to move in the opposite direction relative to the and the adjacent oci guide 2 and the plates 27. The magnitude of the lateral magnetic force is zero for a strictly symmetrical arrangement of the magnets relative to the vertical axis of the guide and increases approximately inversely with the square of the distances between the magnets and the ferromagnet & 1 and the plates 27 reaching at a gap equal to zero, approximately 4 times the lifting force for dawn 10 mm. In order to reduce the pressure from the lateral magnetic forces 5. through 12, the minimum gap (~ 1 km) is chosen between them at a beam 31 at rest or at low speed. The distance between the tips 26 and the plates 27 is taken to be approximately 10 mm. Therefore, the lateral pressure of the side bearings 12 on the beam 31 is approximately equal to 0.04 of the weight of the car. The strength of the friction is equal to 0.004 of the weight of the car (the friction coefficient of the 12 side skirts on the beam 31 is equal to 0.1, which is technically achievable when selecting the appropriate friction surface materials, in the presence of lubricant this value can be significantly less). The gaps between the side bearings 12 and the beam 31 are regulated by the stops 19, and the pressure providing the displacement of the magnets relative to the guide 2 is created by the spring 17 in the absence of air supply under the piston 18 of the pneumatic device. When the crew moves due to the pulling force created by linear induction motors, as a result of the interaction of the inductors 32 and the secondary elements 11, the magnetic field of the permanent magnets induces the vertical rods of the short-circuited EMF circuits 24. These EMFs are the same when the gaps are equal between the cores 2 and magnets 1 from left to right with respect to guide 2. In this case, the current in KOHTypix 24 is zero. In the event that equality of gaps is violated, the EMF in the vertical crepjs x circuits 24 are different. The magnitude of the difference in these EMFs is proportional to the speed of the crew and the difference in induction in the gaps. In the first case, it can be assumed that, in the absence of currents in the terminals of loops 24, their EMF is inversely proportional to the dependence on gaps. Under the influence of Resulting | EMF in short-circuited circuits 24 flows an electric current. Squirrel cage currents 24 are a prerequisite for creating electrodynamic forces. lateral stabilization of this suspension .. When the crew speed is reduced, the pressure is automatically released under the pistons 18 of the pneumatic drive and the clearances are reduced for the Zalka 31 and the sideways 12,
