Description

On the roadway 1, horizontally ALCiueiia is single-layer5 three-phase wave core winding, which is made of sheet conductive material. Winding of active / cnt active 2 and frontal 3.1, 3,2, 4 gears, made in the form of a straight coal power, united with iodine and an angle. The front plates, as active, are located in the horizontal nlooechno. Holes 5 and 6 are formed in the frontal plates, forming parallel rows of short-circuited contours, located symmetrically relative to the longitudinal axis of the track device. Presented in FIG. 1-4, the track devices comprise two eistami. We are parallel rows of holes 5 and 6, made in two layers of frontal connections and located at a small distance from one another. Traveling canvas presented on the FNG. 5, contains only one network. Parallel rows of holes 5 and 6. The distance between the rows of holes 5 and 6 in the non-irregular direction is chosen so that the calculated height of levitation is the sum of upward and downward magnetic field flows passing through the circuit. formed by holes would be zero. When the crew deviates from the axis of symmetry of the track device, the equality of these flows is violated. This is caused in the circuits by the emf and currents appear that, interacting with the magnetic flux, create a force that returns the crew to the middle of the road. The stabilizing force does not develop in the contours, which are located symmetrically under the head of two neighboring katui1 of opposite polarity, which are strengthened on the carriage. To prevent such a situation at the same time not to draw all the contours, it is necessary to perform at least two holes in each frontal plate. If the frontal plates are sufficiently wide, the holes may be located asymmetrically relative to the longitudinal axis of the plastips (cw. Fig. 3, 4). In the remaining portions of the plates, as the crew moves, eddy currents will be induced which will provide additional levitation force. The curve of the distribution of the induction of the magnetic field created by the excitation coil mounted on the carriage has a saddle shape and iodine passes through the conductors of the excitation coil through zero, changing its sign. Therefore, levitational elta in the front plates depends on the relative position of the plates and conductors of the roller. Levitatioppa will grow under the transverse displacements of the crew under one side and increase under the opposite side. This will cause the crew to oscillate about its longitudinal axis. The oscillations are eliminated if the holes in the layers of one layer are shifted to the right, and in the plates of the other layer of the same side of the track device - to the left of the longitudinal axis of the plate plinth, since the transverse displacement of the levitational force developing in one layer of the plates increase, and in the other layer on that side decrease. With a certain arrangement of the plates, the total levitational force acting on the crew from the frontal plates side will remain almost constant with the allowable magnitudes of the transverse displacement of the crew. In cases where a sufficient lateral stabilization force is provided by the system of short-circuited contours of a single layer of frontal plates, the second layer of plates is complete: without holes (see. Fig. 5). It is advisable to place this layer of frontal connections on the track in the form of two parallel rows of such a distance in the transverse direction, so that the plates can be magnetized by the magnetic flux of one sign from each excitation coil. The described track device, in all its variants, is essentially a base plate, the conductors of which are given a special shape. With its constructive simplicity, the track device performs the functions of both the track winding of the engine and the track structures of the electrodynamic suspension and lateral stabilization. Form V of the invention 1.
