Definitions

  • ABSTRACT The present invention relates to an air-column method of controlling the spacing of running bodies when running bodies, say, freight cars, are successively operated on a running path constituted longitudinally within a hollow tube.
  • a running path is constituted longitudinally on the inside surface of a hollow tube.
  • Single freight cars or sets of several freight cars coupled are released or driven to run on this path with an arbitrary spacing.
  • the total area at the end section of the freight car as compared with the sectional area of this hollow tube is selected at a predetermined ratio.
  • the inside profile of the hollow tube and the lateral and sectional profiles of the freight car are appropriately selected such that, when the flow of gas (air) between the outside surface of a running freight car and the inside wall of the hollow tube is made to change, the effective sectional area formed thereby can be secured sufficiently large enough to change the desired result.
  • the present invention relates to an air-column method of controlling the spacing of adjacent freight cars operated in succession with an arbitrary spacing on a running path constituted longitudinally on the inside surface of a hollow tube.
  • a running path is constituted longitudinally on the inside surface of a hollow tube, such as, a hollow cylinder.
  • Single freight cars or sets of several freight cars coupled are released or driven to run with an arbitrary spacing therebetween along said running path.
  • the total area of a freight car at the vertical end section to the running direction against the sectional area of said hollow tube is selected at a predetermined ratio.
  • the inside profile of the hollow tube and the lateral and sectional profiles of the freight car are appropriately selected such, that, when the flow of gas (air) between the outside surface of a running freight car and the inside wall of the hollow tube is made to change, the effective area formed thereby can be secured sufficiently large enough to achieve the desired result.
  • the object of the present invention is to provide a method of preventing an impact collision between two freight cars not by resorting to any special equipment but by simply utilizing, as a means of cushioning or pushing, the air column enclosed between the inside walls of the hollow tube and the opposing ends of freight cars operated in succession along the path formed within the hollow tube.
  • a running path is formed on the inside surface of, say, a hollow tube.
  • freight cars are operated with a certain spacing in succession.
  • the total area of a freight car at its vertical end section to the running direction against the sectional area of the hollow tube is selected at a predetermined ratio.
  • the inside profile of the hollow tube, the lateral and sectional profiles of the freight car are appropriately selected such that, when the flow of air between the outside surface of the freight car and the inside wall of the tube is changed, the effective sectional area formed thereby can be sufficiently wide.
  • FIG. 1(a) is a front elevation view illustrating the basic composition of the present invention.
  • FIG. 1(b) is a front view illustrating the working principle of FIG. 1(a).
  • FIGS. 2(a) 2(a) illustrate examples of embodiment of the present invention.
  • FIG. 2(a) is a front view illustrating the relation between the tube and the freight car.
  • FIG. 2(b) is a side sectional view corresponding to FIG. 2(a).
  • FIG. 2(a) is an oblique view corresponding to FIG. 2(a).
  • FIGS. 1(a) and (b) the air-column method of controlling the spacing of freight cars according to the present invention is to be described.
  • T is, for instance, a hollow cylinder which usually has the same cross-sectional area in the longitudinal direction; 1, 2, and 3 are freight cars running separated by different spacings in the longitudinal direction along the path; and 11, 12, 13 are respectively the gaps between the roof tops of the freight cars I, 2, 3 and the corresponding inside walls of the tube T.
  • the total area of the end of each freight car at its vertical section 445' to the running direction against the sectional area of the hollow tube (sectional area ratio) is selected at a predetermined ratio.
  • the inside profile of the tube T and the lateral and sectional profiles of freight car are appropriately selected such that, when the flow of air between the outside surface of a running car and the corresponding inside wall of the tube T is varied, the efficient sectional area formed thereby can be sufficiently large.
  • the ratio of the area of the end of each freight car to the sectional area of the hollow tube may be small, while the running speed of the car is high; but as the freight car speed diminishes, said ratio may be closer to unity.
  • FIG. 1(b) The above action may, as illustrated in FIG. 1(b), be equated to the cars l, 2, 3 being coupled together by known means of air pistons P P
  • the system illustrated in FIG. 1(a) is equivalent to all the cars operated along the path being united into a single train by a sort of invisible air-coupler; and accordingly, it is possible under this system to control the spacings between freight cars without any braking means. It is clear to anyone that the desired degree of braking in this case can be attained by approximately selecting the adjusting holes PE PE
  • An embodiment of the present invention according to the basic composition shown in FIG. 1(a) is to be illustrated in FIGS. 2(a) 2(a) on the case of freight cars being driven by linear motors.
  • each car is a reaction plate attached to the longitudinal midpoint of the bottom of the body of the car ll".
  • On both sides of said reaction plate 14 and run at a definite distance therefrom are the primary windings 15 of the linear motor.
  • each car can be driven by a known system of linear motor drive using said reaction plate 14- and said primary windings 15 of the linear motor.
  • the system of driving the freight cars to be required in this invention is not limited to the linear motor, but can be any known method such as internal combustion engine or electromagnet; and the type of driving system to be adopted is not essential to the present invention.
  • 16 may be independent wheels installed on both sides of a freight car and said wheels 16 will be designed to run on the rails R laid on the ballast 7.
  • car 2 shown in FIG. 2(a) (c), unlike the car 2 of FIG. 1(a), has end faces or end plate 5, 5 at two ends in the running direction; has no side-wall or roof excepting the part for attaching the wheel 16 and carrying the container 0 on its body.
  • Such a construction of the car 2 will not prevent the effect of this invention from being realized utilizing the end plate 5, 5 in the same way as with the other cars I", 3".
  • the tubes T thus constituted are, as shown in FIG. 2(a), laid side by side as the up-bound track T and the downbound track T; and for instance, the cars 1", 2", 3 as indicated in FIGS. 2(a) and 2(b) are released or driven with an arbitrary spacing. Then, just in the same way as described in FIGS. 1(a) and (b), the group of said cars, even though they have difierent spacings between them, can move on at the same speed, while individual cars are running at equal speeds in the same direction. When, however, one car 1 is decelerated with the other cars running at the unchanged speed, the car 2 will overtake the car 1" and thereby the air column 8 will be compressed to a higher pressure. Thus, on account of the cushioning or pushing action of the air columns 8, 9. and It), the car 2 will be prevented from ramming into the car II" for the same reason as described above with regard to FIGS. 1(a) and (b).
  • a spacing control method for controlling running bodies according to claim 1, wherein the ratio of the total area of a running body at its end section and the sectional area of the hollow tube are so selected relatively that when the flow air between the outside surface of the running body and the inside wall of the tube is changed by a reduction in the distance between successive running bodies, the air column between the running body and a following running body is compressed.
