Abstract
The vehicle 2 includes a vehicle body 21, front wheels 22, and rear wheels 23 provided at positions different from the front wheels 22 in a width direction of the vehicle body 21. The front wheels 22 are mounted at the same height as the rear wheels 23. The track 1 is inclined in the traveling direction of the vehicle 2, and has a front wheel track 11 with which front wheels 22 contact, and a rear wheel track 12 with which rear wheels 23 contact. The front wheel rail 11 and the rear wheel rail 12 are arranged in parallel in a direction orthogonal to the traveling direction of the vehicle 2. In the case of the inclination of the ascending slope, the rear wheel rail 12 is formed at a higher position than the front wheel rail 11. On the other hand, in the case of the inclination of the descending gradient, the front wheel rail 11 is formed at a higher position than the rear wheel rail 12. The difference in height between the front wheel rail 11 and the rear wheel rail 12 is determined by the angle of inclination and the wheelbase L of the axle of the front wheel 22 and the axle of the rear wheel 23.
Description
Technical Field
The present invention relates to a track running system including a track formed as an inclined ground for running of a vehicle, and a vehicle running in the track.
Background
Conventionally, a vehicle such as a cable car that travels on a track formed as an inclined floor (hereinafter, referred to as an inclined track) is known. For example, when a vehicle such as a normal automobile, in which a seat is provided substantially perpendicularly to a chassis, is caused to travel on such an inclined track, the seat is also inclined as the chassis becomes parallel to the track. Therefore, there is a problem that riding comfort is reduced. In order to solve such a problem, a conventional cable car or the like is provided with a seat inclined with respect to a chassis in accordance with an inclination angle of a track, as shown in fig. 5 of patent document 1. However, in this case, when the inclination angle of the rail is changed, the seat cannot be maintained horizontally, and riding comfort may be reduced.
Further, a technique of maintaining the chassis horizontal even when the inclination angle of the rail changes is proposed. In the inclined ground traveling vehicle of patent document 1, a vehicle body on which a person or an object is placed is provided so as to be rotatable about an axis in a direction orthogonal to a traveling direction as a rotation axis. In the inclined ground traveling vehicle, the vehicle body is rotated to become horizontal according to the inclination of the track.
Further, in the horizontal posture maintaining mechanism of the conveyance carriage of patent document 2, a pair of guide rails formed by bending in a concave manner in the traveling direction and arranged in parallel is provided, and the vehicle body swings on the guide rails in accordance with the inclination, thereby maintaining the horizontal posture of the vehicle body.

In the techniques of patent documents 1 and 2, since the vehicle body is kept horizontal by operating in accordance with the inclination of the rail, the vehicle body can be kept horizontal at all times even if the inclination angle changes. However, these techniques are complicated to control and the vehicle body is expensive.
The present invention has been made in view of the above problems, and an object thereof is to provide a technique for maintaining the vehicle body of a vehicle traveling on an inclined track in a horizontal state with a simple configuration.
Means for solving the problems
In order to solve the above problem, a track according to a preferred embodiment of the present invention is a track for running a vehicle, the vehicle including a vehicle body, a front wheel, and a rear wheel provided at a position different from the front wheel in a width direction of the vehicle body, the front wheel and the rear wheel having the same mounting height, the track being inclined in a traveling direction of the vehicle, the track including: the vehicle includes a front wheel rail to which the front wheel is in contact, and a rear wheel rail to which the rear wheel is in contact, the front wheel rail and the rear wheel rail being arranged in parallel in a direction orthogonal to a traveling direction of the vehicle, the rear wheel rail being formed at a position higher than the front wheel rail when the inclination is an ascending slope, the front wheel rail being formed at a position higher than the rear wheel rail when the inclination is a descending slope, a difference in height between the front wheel rail and the rear wheel rail being determined by an angle of the inclination and an axial distance between an axis of the front wheel and an axis of the rear wheel.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 is a schematic perspective view of a track 1 provided as an ascending slope and a vehicle 2 traveling on the track 1. The vehicle 2 of the present embodiment is used for transporting a person riding, for example, a cable car or the like along an inclined ground.
(vehicle)
As shown, the vehicle 2 has a vehicle body 21, two front wheels 22, and two rear wheels 23. Fig. 2 is a view of the vehicle 2 as viewed from the bottom surface. As shown in the drawing, a track width (hereinafter, referred to as a front track width) T of the front wheel 22FA track width (hereinafter, referred to as a rear track width) T with respect to the rear wheel 23RDifferent. Specifically, TF＜TR. In other words, the front wheels 22 and the rear wheels 23 are disposed at different positions in the width direction of the vehicle body 21, and the ground contact position of the front wheels 22 is different from the ground contact position of the rear wheels 23. Therefore, when the vehicle 2 is caused to travel straight, the trajectory of the front wheel 22 and the trajectory of the rear wheel 23 are different positions. The wheel base (hereinafter, referred to as the wheel base) between the front wheel 22 and the rear wheel 23 is L.
(Rail)
as shown in fig. 1, the track 1 includes a front wheel track 11, a rear wheel track 12, and a reference track 13. A drive chain for applying a driving force to the vehicle 2 can be arranged on the reference rail 13. In this case, an engaging portion that engages with the drive chain may be provided on the bottom surface of the vehicle 2 or the like. Of course, other driving force may be applied to vehicle 2, and vehicle 2 may be self-propelled by providing a driving device such as a motor or an engine to vehicle 2 itself. When the vehicle 2 includes a motor, a collector may be provided on a bottom surface or the like of the vehicle 2 to receive electric power from a trolley wire buried in the reference rail 13. In the present embodiment, the front wheel rail 11 is provided at a position higher than the reference rail 13, but the front wheel rail 11 may be provided at the same height as the reference rail 13.
The front wheel rail 11 and the rear wheel rail 12 are arranged in parallel in a direction orthogonal to the traveling direction of the vehicle 2 (hereinafter referred to as an orthogonal traveling direction). Specifically, the front wheel rails 11 are provided on both sides of the reference rail 13 in the orthogonal direction to the travel direction, and the rear wheel rails 12 are provided outside the front wheel rails 11.
As described above, the vehicle 2 is configured such that the rear tread TRGreater than the front track TF. In addition, according to the front tread T of the vehicle 2FRear track TRThe width of the wheels, and the like, the width of the front wheel rail 11 and the rear wheel rail 12 is set so that the front wheel 22 of the vehicle 2 is positioned on the front wheel rail 11 and the rear wheel 23 is positioned on the rear wheel rail 12. Thereby, the front wheels 22 and the rear wheels 23 can be brought into contact with the front wheel rails 11 and the rear wheel rails 12, respectively, and can be rotated on the front wheel rails 11 and the rear wheel rails 12, respectively. Further, it is preferable that the front wheel rail 11 and the rear wheel rail 12 have a surface contacting the wheel, and the like having irregularities for preventing slipping. In this case, the front wheel rail 11 and the rear wheel rail 12 may not be formed with the irregularities, and only the rails corresponding to the drive wheels may be formed with the irregularities.
In addition, as shown in fig. 1, in the track 1 of the ascending slope, the rear wheel track 12 is provided at a position higher than the front wheel track 11. By configuring the track in this manner, the rear wheel 23 is lifted during traveling, and the vehicle body 21 is less likely to descend rearward and downward.
The vehicle body 21 is desirably horizontal so as not to reduce the riding comfort when traveling on the inclined track 1. Fig. 3 is a diagram schematically showing a method of determining the height difference d between the front wheel rail 11 and the rear wheel rail 12 when the vehicle body 21 is horizontal. Here, the height difference d between the front wheel rail 11 and the rear wheel rail 12 is a distance in a direction orthogonal to the rail 1.
let the inclination angle of the track 1 be theta and the center of the front wheel 22 in side view be OF(xF，yF) Let the center of the rear wheel 23 be OR(xR，yR) The radius of the front wheel 22 and the rear wheel 23 is defined as r. The origin O is the point at which the inclination of the rear wheel rail 12 starts. At this time, the y-coordinate y of the center of the front wheel 22 can be expressed by the following numerical expressionsFAnd the y-coordinate y of the center of the rear wheel 23R。
First, the center O of the front wheel 22 can be expressed by the following numerical expressionFY coordinate of (a)RAnd the center O of the rear wheel 23RY coordinate of (a)F。
[ numerical formula 1]
When the body 21 of the vehicle 2 is horizontal, yR＝yF. Therefore, the following relationship is established by the above numerical expression.
[ numerical formula 2]
Multiplying both sides by cos θ solves d as follows.
[ numerical formula 3]
r+d+(xR-L)sinθ＝r+xRsinθ
r+d+xR sinθ-Lsinθ＝r+xR sinθ
d-L sinθ＝0
d＝L sinθ
Therefore, even if the inclination angle θ changes in the middle of the inclined track 1, if the difference in height between the front wheel track 11 and the rear wheel track 12 is configured to be d ═ lssin θ, the vehicle body 21 of the vehicle 2 becomes horizontal. In addition, by gradually changing the height difference d before and after the change of the inclination angle θ, it is possible to suppress a decrease in riding comfort.
Fig. 4 is an enlarged sectional view of the front wheel rail 11. A wheel slip-off preventing wall 11a for preventing wheel slip-off is provided upright on at least one side of the front wheel rail 11 in the direction orthogonal to the traveling direction. In the figure, the rear wheel rail 12 higher than the front wheel rail 11 is provided on the left side in the figure, and this helps to prevent the wheels from slipping out of the vehicle. Although the example in which the wheel-slip preventing wall is provided on the front wheel rail 11 is shown in the figure, the wheel-slip preventing wall may be provided on either or both of the front wheel rail 11 and the rear wheel rail 12.
The track 1 shown in fig. 1 is provided as an ascending slope, but as shown in fig. 5, the track 1 can also be provided as a descending slope. When the vehicle 2 traveling on the track 1 of the ascending slope is steered at the turning back point and travels on the descending slope, the front wheel track 11 is provided at a position higher than the rear wheel track 12. In this embodiment, the positional relationship in the direction orthogonal to the traveling direction of the front wheel rail 11 and the rear wheel rail 12 is the same for both the ascending gradient and the descending gradient.
however, if the higher one of the front wheel rail 11 and the rear wheel rail 12 is disposed on the inner side in the orthogonal traveling direction, the rail 1 may contact the vehicle body 21 of the vehicle 2 when the gradient becomes steep. On the other hand, if the lower one of the front wheel rail 11 and the rear wheel rail 12 is disposed on the inner side in the orthogonal traveling direction, the rail 1 and the vehicle 2 are less likely to contact each other. In this case, it is necessary to reverse the magnitude relationship between the front track TF and the rear track TR at the time of ascending and descending. That is, the vehicle 2 needs to travel to and fro at the turning-back point without turning.
(other embodiments)
(1) In the above-described embodiment, the vehicle 2 has two front wheels 22 and two rear wheels 23, but may be configured as a three-wheeled vehicle in which one of the front wheels and the rear wheels is one wheel. In this case, the front wheel rail 11 and the rear wheel rail 12 may be configured according to the structure of the wheel.
Industrial applicability
The present invention is applicable to a track on which a vehicle having a vehicle body, front wheels, and rear wheels provided at positions different from the front wheels in a width direction of the vehicle body travels, and a track travel system including these members. For example, the present invention can be used not only in a system for transporting persons such as a cable car, but also in a slope (including a member on which a track surface moves) through which a wheelchair or a shopping cart passes, persons in a large commercial facility or a lodging facility, a moving device for articles, and amusement equipment such as an amusement park.
