may be provided with rollers 53 and 54 through which the cable is passed _r so that the cable is located below the receiving apparatus 8 to the correct height so that it can engage on the lead pulley wheels 16 at the curved parts 15 of the track. 3

When operating the vehicle 1 on the track 3 is supported the vehicle with its flanged foot 33 on the high speed belt 4 in the high-speed range, the wheels 27 not engaging in the channels 26. the Control rail 13 is located at a distance from track 3 ■ and the vehicle 1 in a solid line shown in FIG. posed position ", whereupon the cable 7 from the winch 34-" is wound and thereby provides the greatest distance between the vehicle 1 and the neighboring vehicle. The whole endless train 2 is driven by means of the motor 5 Iloch speed belt 4 moved forward. When the vehicle 1 runs off the end of the high-speed belt 4, the wheels 2 7 are directed into the channels 26 / and the vehicle is guided along track 3. The control rail is attached to the track in a position whose distance to the Vehicle 1 becomes increasingly smaller, whereupon the arm 9 is pivoted counterclockwise, as shown in FIG. 7, so that the cable 7 is wound on the winch 34 and the Distance between the vehicle and the neighboring vehicle is shortened, resulting in a deceleration of the vehicle. This delay continues · until the vehicle arrives at the loading / unloading zone, as shown in FIGS. 1 and 2. The vehicle then moves at the same speed as the moving platform.14 so that the passengers can reach the Leave cabin 23 or get into it.

After the vehicle 1 has left the loading / unloading zone and in the acceleration zone, as shown in FIG. 1, the control rail 13 is at an increasingly larger distance arranged by the vehicle and the track 3, whereupon the pivot arm 9 is moved clockwise, as Fig. shows. The cable 7 is disgusted by a winch 34 so that the distance between the vehicle 1 and the neighboring vehicle is increased, resulting in acceleration of the vehicle on the zv / isch.cn of the loading and unloading zone and part of the track lying in the high-speed area.

It is understood that the length of the endless train 2 is substantially the same as the length of the track 3, and that therefore any settings of the control rail 13 offset in terms of greater acceleration on a part of the track through settings on a different part of the track must be in order to provide a greater acceleration. The release of the cable 7 from a vehicle in part of the train 2 is compensated for by the cable 7 being picked up by another vehicle in the train. The cable 7 is preferably made of steel wires and consequently has an elasticity which is sufficient to absorb suddenly occurring tensile and operating forces which are exerted on the system.

8, 9 and 10 is a modified embodiment of the receiving device 8, which can also be attached to the underside of the vehicle 1. At this Embodiment extends the cable 7 through an opening in the transverse part 52 at one end of the vehicle 1 and is between rows of upper disk wheels 55, 'those at an upper Beams 56 are attached, and a number of lower ones

Disk wheels 57, which are fastened to a lower beam 58, passed through, the ends of the cable being fastened to an eye bolt 59 on the transverse part 48. The upper ball 56 and the lower beam 58 have rollers 62 at the ends, which are arranged in transversely extending rail tracks 63 and 64, respectively, which are mounted on the cross members 48 and at the ends of the vehicle - so that the upper one The bar and the lower bar are movable from the positions shown in full lines in Fig. 9 to the positions shown in dashed lines in Fig. 9 for receiving the cable and reducing the distance between the vehicle and an adjacent vehicle. Control rails 65 and 66 are provided along the track under the vehicle 1 and between the channels 26 of the track 3. Curve scanners 67 for the upper beam 56 are firmly connected on vertical parts 68 to the edge of the upper beam 56 for engagement with the control rail 65, so that the upper beam moves from the position shown in FIG. 10 to the right, or, as in FIG. 9 9, when the control rail 66 is moved from the position shown in solid lines in FIG. 9 to the position shown in dashed lines. In the same way, the curve scanners 69 on the lower beam 58 for attack on the control rail in the sense of a movement of the lower beam out of the full lines in E ¹ Ig. 9, the position shown above is arranged in the position shown in dashed lines, with the curves attacking the control rail 66 from button '69. It will therefore be seen that when the control rails 16 and 66 are located in positions off-center of the track 3, the lower beam 58 and upper beam 56 are moved laterally outward and the upper disc wheels 55 and lower disc wheels 57 spread laterally, the path of movement of the cable 7 being changed from the position shown in full lines in FIG. 9 to the position shown in dashed lines.

In operation, the control rails 65 and 66 can operate in the high speed range be interrupted where the vehicle is moving by means of the high-speed belt 4 will. In this regard, the upper disk wheels 55 and the lower disk wheels 57 take those in FIG. 9 position shown in full lines, and the cable 7 extends along its entire length between the vehicle 1 and a neighboring vehicle. When the vehicle 1 is thrown from the end of the high-speed belt 4. and the wheels 27 roll into the channels 26, the control rails 65 and 66 can be positioned between the cam scanners 67 and 69 lying position are interrupted. In the delay area the control rails 65 and 66 are spread apart so that the cam scanners 67 and 69 laterally are pressed outwards and thereby the upper disk wheels 55 and the lower disk wheels 57 laterally outwards lead, wherein the path of movement of the cable 7 below the vehicle 1 is increased and the distance between the vehicle and an adjacent vehicle is decreased. The increasing uptake of the cable is made possible by further spreading of the control rails 65 and 66 over the entire deceleration range continued to the loading and unloading zone, where the vehicles 1 at the same speed as the moving one Platform 14 are driven.

When the vehicle 1 leaves the loading / unloading zone, they are Control rails 65 and 66 are arranged increasingly closer to one another, so that the upper disk wheels 55 and the lower disk wheels 57 laterally inwards towards the center of the vehicle are guided and thereby release the cable 7 from the vehicle and thereby the distance between the vehicle and a Enlarge adjacent vehicle, whereby an acceleration of the vehicle is achieved. The progressive convergence the control rails 65 and 66 lead to the release of more pus
