Definitions

  • the invention relates to a transport system comprising at least one road surface and at least one vehicle on wheels, wherein the road surface has a substantially bowl-shaped cross section and the vehicle is designed so that the wheels run directly on the road surface while the road surface acts as guide for the direction of movement of the vehicle, wherein the vehicle comprises at least one wheel set, wherein for each wheel of the wheel set, the normal of the contact face between the wheel and the road surface is directed perpendicularly to the rotation axis of the wheel.
  • a transport system is known from DE-OS-1580876.
  • a disadvantage of this known system is that the vehicle can only be used in a tube having one predetermined diameter. The vehicle can not be used on a conventional flat road surface and on road surfaces having a bowl-shaped cross section with different radiuses respectively.
  • the invention also relates to a vehicle on wheels suitable for use in the transport system according to the invention , wherein the vehicle is designed so that the wheels run directly on a road surface with a substantially bowl-shaped cross section of the transport system while the road surface acts as guide for the direction of movement of the vehicle, wherein the vehicle comprises at least one wheel set, wherein for each wheel of the wheel set, the normal of the contact face between the wheel and the road surface is directed perpendicularly to the rotation axis of the wheel.
  • transport systems are known, inter alia, for underground transport.
  • the road surface is typically provided in a tunnel tube, with the road surface being of flat construction.
  • the vehicle in question such as, for instance, a motorcar, is then suitable for travelling both inside and outside the tunnel tube.
  • a drawback of this known transport system is that for the control thereof, the vehicle is provided with a complex control mechanism. Typically, such control mechanism should be operated by a person. If this is not the case, the control mechanism will have to be of automatic design. This last is preferred, in particular for underground transport. After all, having to drive such vehicle in an endlessly long tunnel tube is not attractive. Moreover, this entails the risk of control errors being made, considering the little varying background of a tunnel tube. The possible provision of a guide in the tunnel tube for controlling the vehicle is disadvantageous from a logistic point of view.
  • a further drawback is that the portion of the tunnel tube located below the flat road surface is not used for the transport through the tunnel tube. Further, having to work with a guide is disadvantageous at locations where transfer activities takes place.
  • the object of the invention is to overcome the above-outlined drawbacks, and the transport system according to the invention is characterized in that the wheel set comprises means for varying an angle enclosed between the rotation axes of the wheels of the wheel set, wherein said rotation axes lie in a rotation axis plane which, in use, is directed at least substantially perpendicularly to a longitudinal direction of the road surface at the location of the vehicle.
  • the invention offers a number of advantages.
  • the vehicle can run in tunnels of mutually different diameters.
  • the normal of the contact face between the wheel and the road surface is directed perpendicularly to the rotation axis of the wheel.
  • the vehicle is suitable for driving both on a flat road surface and on the road surface having the bowl-shaped cross section. This contact face may be maintained unchanged by setting said enclosed angle accordingly.
  • the vehicle need not be provided with a complex control mechanism and the vehicle can move (rapidly) along a track formed by the road surface, with or without bends, without the vehicle being actively steered by setting the direction of movement of the vehicle.
  • the vehicle will climb up along the bowl-shaped road surface.
  • the center of gravity of the vehicle with respect to the road surface will rise at that location.
  • the vehicle will move back again to the lowest point of the road surface. The course is then restored.
  • the road surface may also be provided with a bend.
  • the vehicle In the bend, the vehicle will climb up along the road surface, with the bend acting as a tub bend. After the bend, the vehicle will, under the influence of gravity, move to the lowest point of the road surface again.
  • a bowl-shaped motorway may be constructed, driven on by motorcars that are only kept at a distance from each other by sensors.
  • the motorcars need not be provided with a control mechanism.
  • the road surface is formed by the inner wall of at least one tunnel tube having a substantially round cross section.
  • a particularly great advantage hereof is that no additional provisions are necessary in the tunnel tube. Indeed, no horizontal road surface needs to be constructed in the tunnel tube. Neither is it necessary to provide the tunnel tube with a mechanism that controls the vehicle. In the event of a disturbance of the linear course of the vehicle, a disturbance which is, for instance, caused by wind and/or a bend in the tunnel tube, the vehicle will temporarily move up along the inner wall of the tunnel tube. Gravity provides that the vehicle subsequently seeks again the lowest point of the tunnel section.
  • a further advantage of the transport system is that no additional provisions to the tunnel itself are required. After all, it is not necessary to construct a flat road surface. Moreover, the volume of the tunnel tube is thus optimally utilized.
  • the transport system according to the invention also offers perspective for transport of passengers through tunnels, such as subway trains moving through tubes without rails.
  • the transport system further comprises a tunnel transition where the lower half of the tunnel tube gradually blends into a flat surface.
  • the flat face is generally directed horizontally.
  • the tunnel transition may then be located at an open end of the tunnel tube, with the flat face being located outside the tunnel tube. This enables the vehicle to drive into and out of the tunnel via the tunnel transition.
  • each of the wheels of the wheel set is connected to the vehicle for rotation about a setting axis through a limited angle, the setting axis being directed perpendicularly to said rotation axis plane.
  • the vehicle may further comprise drive means for setting said angle.
  • said setting axis is positioned below the rotation axis of the relevant wheel. It is thus provided that said angle will set itself, without any active control, such that for each wheel of the wheel set, the normal of the contact face between the wheel and the road surface is directed perpendicularly to the rotation axis of the wheel.
  • said angle will set itself automatically and in such a manner that the normal of the contact face between the wheel and the road surface is directed perpendicularly to the rotation axis of the wheel.
  • the vehicle on wheels according to the invention is characterized in that the wheel set comprises means for varying an angle enclosed between the rotation axes of the wheels of the wheel set, wherein said rotation axes lie in a rotation axis plane which, in use, is directed at least substantially perpendicularly to a longitudinal direction of the road surface at the location of the vehicle.
  • reference numeral 1 denotes a transport system known per se.
  • the transport system comprises a road surface 2 and at least one vehicle 4 on wheels 6.
  • the road surface is provided on the inside of a tunnel tube 8.
  • the vehicle should have a control mechanism to provide that the vehicle keeps following the track of the tunnel tube.
  • a further drawback of the known system is that the provision of the road surface in the tunnel tube entails considerable costs.
  • the road surface 2 is formed by the inner wall 10 of the tunnel tube 8.
  • the tunnel tube 8 has a substantially round cross section.
  • the road surface has a substantially bowl-shaped cross section formed by the inner wall 10 of the tunnel tube 8.
  • the undercarriage 12 of the vehicle 4 is arranged for running directly on the road surface 2.
  • the undercarriage 12 of the vehicle 4 according to Figs. 2a and 2b comprises two identical wheel sets 14.
  • the normal 16 of the contact face 18 between the wheel 6 and the road surface 2 is directed perpendicularly to the rotation axis 20 of the wheel. This involves, inter alia, the normal 16 intersecting the center M of the tunnel tube.
  • the tread of the wheel is optimally utilized for discharging the weight of the vehicle onto the road surface 2 formed by the inner wall of the tunnel tube.
  • the road surface will also act as a guide for the vehicle.
  • the vehicle will travel in the center of the tunnel, which means that the vehicle is located at the lowest point of the tunnel.
  • the vehicle leaves this ideal position, for instance because the tunnel tube makes a bend or because the linear movement of the vehicle is otherwise disturbed by, for instance, irregularities in the road surface and/or air flows in the tunnel tube, the vehicle will move up along the road surface.
  • the mass center will likewise be moved up.
  • any deviation from the ideal path through the tunnel tube involves the mass center of the vehicle being moved up.
  • Gravity then causes the vehicle to move down again. In other words, the vehicle will resume its ideal position in the tunnel tube.
  • the vehicle In a bend, the vehicle will move up along the tunnel wall, as stated, with the road surface acting as a tub bend. After the bend, the vehicle finds its own way back to the lowest point in the tunnel.
  • the advantage of this is that the vehicle need not be provided with an active control. In other words, the vehicle need not be controlled.
  • the transport system according to the invention also involves an enlargement of the usable space of the tunnel tube. This enlargement of the tunnel tube becomes immediately apparent from Fig. 3.
  • FIG. 3 On the right-hand side of Fig. 3, the conventional transport system according to Figs. 1a and 1b is shown. On the left-hand side of Fig. 3, an embodiment of the transport system according to the invention is shown. This directly demonstrates that the volume of the vehicle (hatched in Fig. 3) according to the invention can be larger than the volume of the vehicle of the conventional transport system.
  • each wheel is constructed as a double wheel.
  • wheel should be understood to include the following: a single wheel and also a number of wheels that are positioned adjacent each other and rotatable about the same rotation axis.
  • the wheel sets 14 comprise two double wheels 6, 6'.
  • the double wheels 6, 6' in fact form one wheel.
  • the wheel set comprises means 22 for varying an angle ⁇ enclosed between the rotation axes 20 of the wheels 6, 6'.
  • the rotation axes 20 lie in a plane perpendicular to an axial direction of the tunnel tube at the location of the vehicle, in other words perpendicular to the longitudinal direction of the road surface at the location of the vehicle.
  • the rotation axes 20 lie in the plane of the drawing.
  • the enclosed angle ⁇ mentioned is less than 180°.
  • the means mentioned for varying the angle ⁇ are realized in that at least one wheel 6, 6' and in this case even both wheels 6, 6' of the wheel set are connected to the vehicle for rotation about a setting axis 24 over a limited angle.
  • the setting axis 24 is directed perpendicularly to said plane.
  • the setting axis 24 extends in the same direction as the axial axis of the tunnel tube.
  • said setting axis is located below the rotation axis 20 of the relevant wheel 6, 6'.
  • the wheels of the vehicle automatically assume a rotational position around the setting axis 24 such that to these wheels, it applies that the normal of the contact face between the wheel and the road surface is directed perpendicularly to the rotation axis of the wheel.
  • the vehicle according to Fig. 4 of the invention can be used in tunnel tubes of varying diameters.
  • the vehicle can also move on a conventional, flat road surface. This situation is shown in Fig. 4c. Under the influence of gravity, the wheels will automatically assume this position.
  • the transport system further comprises a tunnel transition 26 where a lower half of the tunnel tube gradually blends into a flat surface.
  • This flat face may be directed horizontally.
  • the tunnel transition will then typically be positioned at an open end of the tunnel tube, with the flat face located outside the tunnel tube. Consequently, via the tunnel transition, the vehicle can drive into and out of the tunnel in a simple manner. Also when the vehicle is out of the tunnel, it can move on as usual.
  • the invention also offers perspectives for the transport of passengers through tunnels. In this respect, one may think of subway trains moving through tubes without rails at a great penetration power, as they can also run on a flat road.
  • the gradual tunnel transition 26 to a flat road surface 28 is shown in Fig. 4b.
  • the lower half of the tunnel tube gradually blends into a flat face formed by the flat road surface 28.
  • a further elaboration is given of a wheel of a wheel set according to invention.
  • One wheel 6 of the double wheel is driven by a hub motor 29.
  • the other wheel 6' of the double wheel rotates along freely.
  • the double wheel is accommodated in a support arm 30 capable of rotating by means of a turntable 32 around a steering axis 33 of a bearing part 34 of the vehicle.
  • the vehicle can be steered when running on a flat road.
  • the setting axis 24 lies again below the rotation axis 20. Consequently, the wheel will automatically adopt the positions as shown in Figs. 5b and 5c respectively.
  • the wheel set comprises drive means for setting the above-mentioned enclosed angle ⁇ .
  • a servomotor capable of causing the wheels to rotate about the axes 24 may for instance be used.
  • this servomotor is schematically designated by reference numeral 36.
  • the vehicle comprises two wheel sets 14 which each have two wheels 6.
  • Each wheel may be designed as a double wheel 6, 6'.
  • the vehicle comprises one wheel set 14 having one pair of wheels 6, 6', as made clear with reference of Figs. 6a-6c.
  • the vehicle further comprises a wheel 38 positioned approximately in the middle of the vehicle. In fact, this is a tricycle.
  • the operation of the vehicle is entirely analogous with the operation as described in the foregoing with reference to the Figures discussed earlier.
  • the wheels 6, 6' of the wheel set 14 will adapt themselves to the curvature of the road surface.
  • the vehicle will in principle not lie entirely horizontally when located in the tunnel tube.
  • the vehicle will slope downwards in a direction from the wheel set 14 towards the wheel 38.
  • this can be compensated for by rendering the wheel 38 height-adjustable.
  • Such variants are each understood to fall within the framework of the invention.
  • the vehicle according to the invention may be provided with more than two wheel sets. It is also conceivable that a wheel of a wheel set is composed of one or more double wheels 6, 6', 6'', 6''' having different yet closely spaced rotation axes, as shown in Fig. 7. In this application, the term "wheel" of a wheel set should therefore be given a broad interpretation.
  • the transport system according to the invention could use motorways having a bowl-shaped road surface in cross section. In this respect, one may think of bowl-shaped motorways driven on by motorcars that are only kept at a distance from each other by sensors.
