Abstract

PURPOSE:To contrive the orientation to a high speed and low noise with rubber tires possible in use by additionally providing respectively a primary side coil of synchronous linear motor in a track side further a magnet in a car body side and setting an air gap between primary and secondary sides of the linear motor to not less than a specific range. CONSTITUTION:A monorail vehicle, which runs at a high speed with low noise further with low vibration, is set to a rubber tire supporting guide system. The monorail vehicle is constituted, for instance, in a bestriding type, and a plurality of running wheels 23 and guide wheels 24, arranged in the lower surface of a car body 26, are respectively brought into contact with upper and both side surfaces of a track 25. Here a primary side coil 28 of a synchronous linear motor is molded into plate shape and additionally provided in the track 25. While a field electromagnet or permanent magnet 27 is additionally provided in the car body 26. An air gap between primary and secondary sides of the linear motor is set to not less than a deflection changing range of a rubber tire. In this way, respective rubber tires can be used for each of wheels 23, 24 respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for running a monorail vehicle at high speed, with low noise, and with low vibration.

(Prior Art) As prior art, FIG. 1 shows a straddle-type monorail, and FIG. 2 shows a suspension-type rubber tire supported and guided monorail.

The rubber tire supported and guided monorail runs using the adhesive force between the rubber tires 3 and the track 5.

In FIGS. 1 and 2, 1 is a running girder, 2 is a bogie, 4 is a guide wheel, and 6 is a vehicle body.

(Problems to be Solved by the Invention) Conventional monorail running relies on the adhesive force between the rubber tires 3 and the track 5, so there is a limit to the amount of driving force, and noise generation from the reduction gear is unavoidable. There was a problem.

In order to solve these problems, a near-motor type motor has been proposed in which the primary side of the linear induction motor is attached to the vehicle and the secondary side conductor plate is attached to the track.

However, this method is not effective as a noise countermeasure because an induced current is generated on the secondary side by the moving magnetic field generated on the negative side, so the gap between the negative side and the secondary must be kept to a small value. Some rubber tires cannot be used and metal wheels are used. For this reason, there were problems with noise and vibration generated from the metal shaft.

(Means for Solving the Problems) In order to solve the above problems, in the present invention, the primary coil of the synchronous linear motor is formed into a plate shape and attached to the track,
By supporting and guiding rubber tires, monorail vehicles can run at high speed and with low noise.

(Function) In the monorail vehicle described above, a synchronous linear motor having a primary coil formed into a plate shape is used for driving force, and rubber tires are used for supporting and guiding the vehicle.

(Embodiments) Next, specific embodiments of the system of the present invention will be described in detail with reference to the drawings.

Figure 3 shows the straddle type, and Figure 4 shows the suspension type.

The primary coil 28 of the synchronous linear motor is formed into a plate shape and attached to the track 25, and the vehicle side is equipped with a field electromagnet or permanent magnet 27, so that the gap between the primary and secondary coils can be used to compensate for the deflection fluctuations of the rubber tires. This makes it possible to provide the wheels larger than the range, and allows the running wheels 23 and guide wheels 24 to be made of rubber tires.

Furthermore, since the primary side of the linear motor is provided on the track side, on-board electrical equipment is simplified and the weight of the vehicle can be reduced.

In FIGS. 3 and 4, reference numeral 23 indicates a running wheel 24, a guide wheel, 26 a vehicle body, 27 a magnet, and 28 a primary coil.

(Effects of the Invention) By the running method of the present invention, a Morsir military vehicle can be run at high speed, with low noise, and with low vibration.
