Description

Detailed Description of the Invention (8) [Technical Field] The present invention relates to a transportation device using a vehicle and two rails, and its vehicle and track.

[Prior art]

Developed in 1987 as a transportation device that can travel on conventional minimal curves.
No. 79061 ``Running guide device for track vehicles'' has been proposed.In addition to two running rails, a guide rail is laid in the center of the track so that the wheels do not cross the running wheels. By limiting the direction of the vehicle, it is possible to travel smoothly on minimal curves with little lateral pressure. However, in addition to the two running rails, it is necessary to install a guide rail in the center of the track, which accounts for most of the construction cost.
There is a disadvantage that construction costs increase, and furthermore, it is difficult to reverse (reverse) with this device. Therefore, in order to make it possible to go backwards, the idea was similar to that of the ``Railway Car Bogie'' No. 1045, which had a mechanism for switching between forward and backward motions and aimed at reducing lateral pressure.
Utility Model Application Publication No. 56-27168 ``Steering and Guidance Device for Heavy Load Transport Truck'' based on JP-A-57-742
No. 69 "Direction Control Device for Trolley" has been proposed. However, these require three rails across the entire track, and on curved roads, two types of rails are required: one for forward movement and one for backward movement (although they are connected vertically, functionally there are two types of rails). The track, which is a book rail, has a complicated structure, which poses problems for practical use. Furthermore, the structure of the vehicle is becoming more complex by switching between forward and forward motion.

[Purpose of the invention]

The present invention eliminates all of these drawbacks; the track has only two rails, and in addition to the running wheels, the vehicle is only provided with a set of guide rollers for each running wheel so that they can swing horizontally. With a simple structure, the guide roller smoothly follows the rail on a curve with an extremely small radius and has the same performance in both forward and backward directions, thereby reducing the lateral pressure generated on the tread surface of the running wheels and smoothing out the running of the vehicle. The purpose is to allow the guide rollers to follow the rails smoothly even on curved roads with extremely small curve radii, approximately 2 to 5 times the distance between the left and right rails, and for the running wheels to run smoothly with little lateral pressure and with the same performance in both forward and backward directions. To provide a transportation device, its vehicle, and a track, which can move the vehicle forward and backward, do not require a separate guide rail, etc. to obtain the effect, do not require a switching operation for forward and backward movement, and have a simple structure due to cracks, etc. It is something to do.

(11) An object of the present invention is to provide a transportation device that has a long life, with less wear on running wheels and other parts, and less wear on rails, and a vehicle and track thereof. It is a transportation device including a vehicle and a running track with two rails, and each bogie frame 10 has running wheels 1°2 that can each rotate independently, and the distance between the rails B1 + B2 is equal to 1 each on the left and right sides at intervals
Each wheel is provided with a distance from one running wheel 1 in the forward direction of the vehicle AK from the center of the running wheel 1, and a distance B1 in the lateral direction from the center line E-E of the vehicle. position, and has a distance L2 from the other traveling wheel 2 to the center of the traveling wheel 2 in the backward direction O of the vehicle, and a distance B2 in the lateral direction (from the (12) center line E-E) of the vehicle. Swinging beams 5 and 6 having rotation centers P and Q and capable of horizontal rotation are provided at positions P and Q, respectively, and each of the swinging beams is provided with a plurality of guide rollers 7 and 8, and each of the corresponding rails. 3 and 4, and the bogie frame 10 is supported via a center plate 11 with respect to the car body 9 above the central portion of the bogie frame 10 so that the entire bogie can rotate horizontally. The vehicle is composed of two vehicles and nine vehicle bodies, and on a straight road, the two rails installed on the ground are on the forward direction A side of the vehicle with respect to the radius R of the center of the track. When the arranged guide roller 7 is outside the curved road, the position of the rail 3 is a distance L1 from the center of the running wheels of the two-wheeled bogie in the forward direction A of the vehicle, and The distance RO from the center of curvature 0 is RO=Yiτ1〒j〒>2

A distance L1 is taken from the center in the forward direction A of the vehicle, and a distance R4 from the center of curvature O of the curved road is Ri = Y (RB+
)' If the guide roller 8, which is located at the position where the vehicle is traveling in the backward direction C, is located outside the curved road, the position of the rail 4 is such that the two-wheeled bogie and one bogie are traveling. A distance L2 is set from the wheel center in the backward direction C of the vehicle, and the distance RO from the center of curvature 0 of the curved road is Ro=(B+B2)

When the guide roller 8 disposed on the side is on the inside of a curved road, the position of the rail 4 is at a distance L2 from the center of the running wheels of the two-wheeled bogie in the backward direction 0 of the vehicle, and on the curved road. The distance Ri from the center of curvature 0 of the road is R1,=(RB2p
+ L2', the vehicle and track thereof are characterized by being laid so as to substantially coincide with each other, and the running track is formed by these two rails, and the vehicle and track thereof. 0 [Description of Embodiment] An embodiment of the present invention is shown in FIGS. 1 and 2. FIG. 1 is a side view, and FIG. 2 is a plan view with the vehicle body removed. The running wheels 1 and 2, which are provided on both the left and right sides of the front and rear parts of the vehicle body 9, have a structure that allows each to rotate independently (
bearings etc. are not shown), and rails 3 and 4
(1b) with an interval equal to the distance between the rails, and assuming that the running direction is in the direction of the arrow mark, the distance is in front of the running wheel 1, that is, in the direction A, from the center of the running wheel. L
1, and a two-wheeled guide roller 7 with two flanges acting on both sides of the rail 3 is horizontally oscillated at a position B1 in the left-right direction from the vehicle center line E-E via the oscillating beam 5. It is movably supported by the bogie frame 10, and the swinging beam 5 is an arm for supporting the swinging beam in the direction of the rail 3 by the action of the flange of the guide roller 7. The guide roller 7 can of course be moved. Two wheels having two flanges acting on both sides of the rail 4 are located behind the running wheels 2, that is, at a distance L2 from the center of the running wheels in the direction C, and at a position B2 in the left-right direction from the vehicle center line E-E. The guide roller 8 moves through the swinging beam 6 (
1b) and is supported by the bogie frame 1o so as to be horizontally swingable.

The operations of the swinging beam 6 and the guide roller 80 are the same as in cases 5 and 7 described above. The car body 9 is supported by a center plate 11 which allows the entire bogie, including running wheels, guide rollers, the bogie frame, etc., to rotate horizontally relative to the car body 9 on the upper surface of the central part of the bogie frame 1o. ^ The track is constructed by laying two rails 3 and 4, and as shown in the figure, the distance between the two rails is B on a straight road.
1 + B2. Of course, B1 and B2 can also be made equal in value.

Looking at the relationship between the above-mentioned two-wheel bogie and two JILA rails, the spacing between the two rails is B1 + B2.

Only in this case is the center line of the running wheel running straight in the direction of the rail, but if the interval between the two rails 3゜4 becomes wider than the predetermined interval B1+B2, the running wheel The center lines of 1 and 2 will be rotated clockwise when viewed from above, and conversely, if the distance between the two rails is narrower than the specified distance, the center line of the running wheels will be rotated in the opposite direction. When rotated clockwise, the running wheels form an angle with the rail direction, that is, with the traveling direction. If the rail spacing becomes wider, the opposite situation will occur. In this way, in the point symmetrical arrangement of the guide rollers according to the present invention, the present invention 2
The direction of the running wheels can be forced by adjusting the spacing between the two rails. Therefore, on a straight road, by keeping the spacing between the two rails at B1+B2, the rolling direction of the running wheels always matches the direction of the rails. FIG. 3 is a plan view showing the relationship between the positions in which the running wheels are made to coincide with the direction of the curved road by taking a rail spacing that matches the curved road even on a zero curved road where the vehicle can travel on the curved road. The center line E-E indicates the center of the track where the straight road reaches the curved road, and the center of the two-wheeled bogie is to pass on this line as a locus.The line to the right of point BTO is a straight line, The two rails have a BI 10 B2 relationship. Point B'l"0 and point 8
000 is a transition curve, B'l'0 diameter R changes gradually, R is infinite at l=O, R is at /=TOL
corresponds to Rc (radius of the circular curve). There are various types of curves, but when the minimum curve radius is targeted, a clothoid curve in which R changes in inverse proportion to l is most suitable. No matter which curve is used, it is natural that the position of the zero point of the center of curvature changes as l changes.

゛From this point of view, the attitude of a two-wheeled bogie on a curve should always be such that the center line of the running wheels is facing the center of curvature. are determined, and the position to be located at the same time is definitive, so that the installation can be done accordingly. As shown in the figure, if the rail on the outside of the curve takes Ll in the direction of A from the center of the running wheel, and the distance from the center of curvature O is RO, then the rail on the inside of the curve takes the center of the running wheel. From C
If L2 is taken in the direction of , and the distance □ from the center of curvature O is Ri, then the position will be □. In addition, when the direction of the curve is opposite to that shown in the diagram, the rail on the outside of the curve takes L2 from the center of the running wheel toward the cow C, and if the distance from the center of curve repair O is Ro, then (not shown), the rail on the inside of the curve is determined to be at a position (not shown) where Ll is taken from the center of the running wheel in the direction of A, and the distance from the center of curvature 0 is R4. Although the illustrated circular curve is indicated by the radius Ro, the positions of the two rails in that section are also determined in the same manner as described above. Assuming that a clothoid is used for the transition curve, the coordinates of the track center and rail position in the transition curve are as shown in the following equation. ψ, x, x1

2 sin ψ - L2008 ψ As mentioned above, by laying the rails, the center line of the running wheels is exactly 90 degrees from the rail direction on a straight road, and coincides with the center of curvature on a curved road. In other words, the running wheels face in the direction in which the vehicle is moving, and as the vehicle moves, there is no lateral bevel between the running wheel tread and the top surface of the rail.The absence of a lateral bevel means that lateral pressure is It means zero. In addition, the error angle between the traveling direction of the vehicle and the shifting direction of the running wheels, which occurs due to errors in rail installation;
So, the sideslip angle is now the distance error between the two rails as 5am, Ll =
Assuming L2 = 100011g, the error angle is 0.0
025 rad. On the other hand, the range in which side slip between a general steel wheel and a steel rail is within the elastic range and there is no actual slip is a sideslip angle of about 0.003 rad. therefore,
If the rail installation error is within about 5 degrees, the treads of the running wheels will not develop sagging, and the rails and running wheels will not wear out. Also, not causing sideways bumps also leads to smooth running. Furthermore, one swinging beam has two guide rollers, and these two
By the action of the flanges of the guide rollers, the swinging beam is automatically aligned with the direction of the rail. As a result, the guide roller rolls smoothly and follows the rail. Since it rolls smoothly in this way, there is little wear on the flange, but it has the disadvantage of requiring wheel replacement after long-term use. However, the only space occupied on the sides of the rail is the thickness of the flange, which is much smaller than the horizontally rotating guide roller described later. For this reason, when cutting out a mating rail due to intersection with another track, etc., the size can be reduced, which is a great advantage and has great application value.

FIGS. 4 and 5 are plan views of a truck showing other embodiments of the present invention, and FIG. 4 shows two horizontally rotating guide rollers 17 and 18 each acting on a swinging beam 15 and 16 on the side surface of the rail. In FIG. 5, four horizontally rotating small-diameter guide rollers 27, 28 are provided on each swing beam 25, 26.

These horizontally rotating guide rollers have the advantage that all friction parts are smoother than the flanged guide rollers of FIGS. 1 and 2, and that they have very little wear. In the case of FIG. 5, the diameter of the guide roller is smaller than that of FIG. 4, and the space occupied on the side of the rail is reduced.

FIG. 6 is a plan view of a trajectory that does not use a transition curve. As shown in the figure, when there is no transition curve, both the outer rail and the inner rail of the curve have a bent shape at the point of transition between the curve and the straight line. When a transition curve such as a clothoid curve is provided, the installation design of the rail is simple, which is an advantage, but horizontal rotation of the bogie suddenly occurs at the transition point between the curve and the straight line, which is unfavorable for vehicle movement.

Therefore, it is not suitable for running at the highest possible speed, but is used when the speed is slow, taking advantage of the simplicity of the installation design. The arrangement of guide rollers shown in FIG. 4 is most suitable for following such a broken rail.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, almost 797% of the various disadvantages, inconveniences, and shortcomings found in the trolleys and running tracks included in conventionally known transportation devices of this type are eliminated. Therefore, it is possible to provide a vehicle which has a simple structure and can run smoothly even on a curved road having an extremely small radius of curvature, with the guide rollers smoothly following the rails and generating less lateral pressure on the running wheels.

Note that the present invention can also be applied to vehicles with an articulated structure. In this case, one truck may be placed at the joint of the two vehicle bodies, so that each vehicle can be used as a common vehicle.
