DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a magnet belt drive type vehicle, FIG. 2 is a side view of the magnet belt drive type vehicle, FIG. 3 is a sectional view taken along line III-III in FIG. 2, and FIG.
[0006]
In the figure, the track R on which the magnet belt drive type vehicle 1 travels is made of concrete having a rectangular cross section, and has a travel surface R1 on which wheels are mounted, and iron plates are stretched on both sides, and a magnetic adsorption surface R2. Is configured. The trolley line T is laid on the side of the track R in parallel therewith. The magnet belt drive type vehicle 1 obtains drive power from the trolley line T and travels across the track R.
[0007]
The magnet belt drive type vehicle 1 includes a carriage 2 and a vehicle body 3 mounted on the top thereof. A traveling wheel 6 is pivotally supported by a horizontal axis 5 on the frame 4 of the carriage 2 so as to roll on the traveling surface R1 of the track R. The guide wheels 8 are pivotally supported on the vertical axis 7 so as to oppose each other.
[0008]
As shown in FIGS. 2 and 3, the magnet belt unit 9 is attached to the lower portion of the frame 4 of the carriage 2 so as to face each other. The magnet belt unit 9 is provided on the frame body 10. On the frame 10, a pair of front and rear pulleys 11 and 12 are pivotally supported by vertical axes 13 and 14. A magnet belt 15 is wound around the pulleys 11 and 12. The magnet belt 15 is formed by fixing a large number of permanent magnet pieces to a belt base made of an elastic synthetic resin, and can rotate while being attracted to the magnetic attracting surfaces R2 on both sides of the track R. A motor 16 is fixed on the frame body 10 and transmits rotation to the pulley 11 via a speed reducer and a transmission mechanism. The driving power of the motor 16 is supplied from the trolley line T via the current collector 16.
[0009]
The frame 10 that supports the magnet belt unit 9 is swingable to the frame 4 of the carriage by a first link 19 at an inner position close to the track R and a second link 20 at an outer position far from the track R. It is suspended. The suspension fulcrum of the links 19 and 20 is set at a position where the magnet belt unit 9 applies a rotational moment (inward rotational moment) in a direction in which the magnet belt 15 always presses the magnetic belt 15 against the magnetic attracting surface R2 of the track R by its own weight. ing. This rotational moment prevents the lower magnet belt from leaving the magnetic attraction surface in the inclined part of the track. A connecting member 21 is interposed between the first links 19 of the magnet belt units 9 on both sides. The connecting member 21 connects the links 19 with a predetermined elastic tension. The connecting member 21 has a spring 24 interposed between a first support member 22 and a second support member 23. The first support member 22 is a rod-shaped body, and one end is pivotally supported by one first link 19 (left side in FIGS. 3 and 4). The second support member 23 has a rod-shaped one end pivotally supported by the other first link 19 (right side in FIGS. 3 and 4), and the cylinder-shaped other end side is connected to the other end side of the first support member 22. It accepts relative displacement in the axial direction. At the other end of the support member 22, a pin 22 a is implanted in the direction orthogonal to the axis, and this pin 22 a penetrates the long hole 23 a in the axis direction of the second support member 23 movably. The spring 24 is interposed between the spring receiving rod 23 b on the second support member 23 and the pin 22 a of the first support member 22, and the first support member 22, the second support member 23, Are compressed when they are displaced relative to each other in a direction away from each other by a predetermined distance or more.
[0010]
Thus, the magnet belt driven vehicle 1 travels on the track R by rotating the magnet belt 15 while attracting the magnet belt 15 to the magnetic attracting surfaces R2 on both sides of the track R. Normally, the pair of magnet belt units 9 is pressed against the magnetic attracting surface R2 of the track R by an inward rotation moment and magnetic attracting force due to its own weight. Even at locations where the cant angle is attached to the curved portion of the track R, the separation from the magnetic attracting surface R2 is suppressed by the rotational moment and the magnetic attracting force. When the vehicle travels at a higher speed or where the cant angle of the track R is larger, it becomes difficult for the magnet belt 15 to maintain contact with the magnetic attracting surface R2 only by the magnetic attracting force and the rotational moment. There can be. In such a case, in addition to the rotational moment of the magnet belt unit 9, the magnet belt 15 positioned on the lower side of the inclination is detached from the magnetic attraction surface by the spring force of the spring 24 of the connecting member 21. To prevent. At other locations, the pair of magnet belt units 9 freely swing within a predetermined range as necessary, and smoothly travel on the track.
[0011]
【The invention's effect】
As described above, in the present invention, in the magnet belt drive type vehicle 1, the traveling wheel 6 is attached to the frame 4 of the carriage 2 so as to roll on the traveling surface R1 of the track R, and the magnetic adsorption surface of the track R is also measured. A pair of magnets are mounted on the frame 4 of the carriage 2 so that the guide wheels 8 are attached to the frame 4 of the carriage 2 so as to roll on the R2, and the magnet belt 15 is attracted to the magnetic adsorption surface R2 of the track R. The belt unit 9 is attached, and the magnet belt 15 is rotated in the extension direction of the track R by driving by the motor 16 so as to propel the carriage 2. The magnet belt unit 9 has a first link 19 at a position close to the track R, respectively. And a second link 20 at a position far from the track R in a direction in which it is swingably supported by the frame 4 of the carriage 2 and the magnet belt 15 is always pressed against the magnetic adsorption surface R2 of the track R by its own weight. Times Since the rolling moment is applied, it is possible to effectively prevent the lower magnet belt 15 from being separated from the magnetic attracting surface R2 by its own weight in the inclined portion of the track R.
