Definitions

  • the load support carriages 10 for example seats 11 of a chairlift, roll in the station, after uncoupling the cable, on a transfer rail 12.
  • a transfer rail 12 Along the rail 12 are regularly staggered wheels 13 to pneumatic tire 15 which cooperate with a cross member 14 of adhesion, carried by the carriage 10.
  • the wheels 13 are driven in rotation by a motor, not shown, or by a power take-off on the cable and they are connected together by transmission belts 16 which pass over pulleys fixed on the axes of the wheels 13. In normal traffic areas the wheels 13 are driven at the same speed which corresponds to the speed of movement of the carriage 10 with the seats 11.
  • the first wheel In the area of deceleration the first wheel, has the entrance to the station rotates at cable speed while the speed of the following wheels decreases progressively to reach normal circulation speed. This decrease in the speed of rotation of the wheels 13 results from drive pulleys of different diameters or by any other means. Similarly, the speed of the wheels 13 increases in the acceleration zone, as they approach the exit.
  • the length L of the cross-member 14 is slightly greater than the distance D between two successive wheels 13 so as to always be in contact with at least one friction wheel 13.
  • the cross-member 14 does not have a uniform adhesion over its entire length L, the adhesion of the central part 19 being greater than that of one or more zones or end parts 17,18.
  • central 19 must be sufficient to drive the carriage 10 by a single wheel 13.
  • FIGS. 2 to 4 it can be seen in FIGS. 2 to 4 that when an end zone 17, 18 is in contact with a wheel 13, another zone of the cross-member 14 is in contact with another wheel 13 and the cross-member 14 is driven by two wheels.
  • the front zone 17 engages the next wheel 20 while the previous wheel 21 still cooperates with the central zone 19.
  • the two end zones 17,18 cooperate respectively with the wheels 20 and 21 and in FIG.
  • the invention consists in preventing the area or areas of high grip of the cross member 14 are engaged simultaneously by two friction wheels 20,21.
  • the difference in the adhesion of the cross member 14 may result from its surface condition in particular from its roughness and in FIGS. 5 and 5a, a cross member 14 has been shown having a smooth front zone 17 and rough central 19 and rear 18 zones. In the position shown in FIG. 5, which corresponds substantially to that of FIG. 2, one of the wheels 20 is in contact with the smooth zone 17 and the other 21 in contact with the rough zone 18,19.
  • FIGS. 8 and 8a illustrate another means of modifying the adhesion, which consists in placing the zone of weak adhesion 17 slightly set back, that is to say at a slightly greater distance from the axis of the wheel 20
  • the pneumatic tire 15 of the wheel 20, in contact with the recessed area 17, is thus less squashed, with a contact surface and less grip.
  • the area of reduced grip can be, as mentioned above, at the front or at the rear of the sleeper.
  • the surface finish and the material are the same along the entire sleeper 14, but we can design combinations, the recessed portion 17 being, for example, at the same time less rough.
  • the passage from one zone to another can be gradual to ensure a less brutal transition.
  • the constraints and thereby the wear of the wheels of friction 13 and transmissions 16 are thus reduced and additional means of damping the differences in speed, on the acceleration and deceleration sections, are generally superfluous.
  • the invention is of course in no way limited to the embodiment more particularly described.

Claims (9)

  1. Vorrichtung zum Antrieb von Fahrzeugen in den Stationen, insbesondere Kabinen oder Sesseln (11), von einer Luftseiltransportanlage mit einem dauernd umlaufenden Seil und mit einem Entkuppeln der Fahrzeuge in den Stationen, welche Fahrzeuge dann auf einer Überführungsschiene (12) rollen, wobei längs dieser Schiene gestaffelte Reibantriebsräder (13) mit einer länglichen, in der Bewegungsrichtung sich erstreckenden Adherenzleiste (14) zusammenwirken, deren Länge (L) grösser als der Abstand (D) zwischen zwei aufeinanderfolgenden Reibrädern (13) ist, wobei die genannte Leiste an dem Fahrzeug befestigt ist, dadurch gekennzeichnet, dass auf den Beschleunigungs- und Abbremszonen der Fahrzeuge, die Reibräder (13) immer verschiedene Drehgeschwindigkeiten haben, dass die AdherenzLeiste (14) eine zentrale Zone (19), zum Antrieb der Leiste durch ein einziges Reibrad (13) und Endzonen (17,18), zum gleichzeitigen Antrieb durch zwei aufeinanderfolgende Reibräder, mit verschiedenen Drehgeschwindigkeiten, aufweist, und dass die genannte zentrale Zone (19) eine genügend grosse Adherenz, zum Antrieb des Fahrzeuges (11) ohne Rutschen aufweist, während zumindest eine Endzone (17,18) eine verminderte Adherenz aufweist, die ein relatives Rutschen zwischen der Zone mit einer verminderten Adherenz und dem mit dieser Zone zusammenwirkenden Rad (13) ermöglicht.
  2. Antriebsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Leiste (14) eine einzige Zone (17) mit einer verminderten Adherenz aufweist, deren Länge ungefähr dem Unterschied zwischen der Leistenlänge (L) und dem Abstand (D) zwischen zwei aufeinanderfolgenden Rädern (13) entspricht.
  3. Antriebsvorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass die Zone mit einer verminderten Adherenz am vorderen Ende (17), gesehen in der Bewegungsrichtung der Leiste (14), liegt.
  4. Antriebsvorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Leiste (14) zwei Zonen mit einer verminderten Adherenz aufweist, die beziehungsweise in den zwei Endzonen (17,18) der Leiste liegen.
  5. Antriebsvorrichtung nach einem der vorigen Ansprüche, dadurch gekennzeichnet, dass die Adherenz längs der Zone mit einer verminderten Adherenz variiert, insbesondere beim Übergang zu der Zone mit einer grossen Adherenz.
  6. Antriebsvorrichtung nach einem der vorigen Ansprüche, dadurch gekennzeichnet, dass die Zone mit einer verminderten Adherenz einen Flächenzustand mit einem geringeren Reibkoefficient als die Zone mit einer grossen Adherenz hat.
  7. Antriebsvorrichtung nach einem der vorigen Ansprüche 1 bis 5, dadurch gekennzeichnet, dass der Adherenzunterschied zwischen den beiden Zonen (17,18,19) der Leiste (14) von der Benutzung eines verschiedenen Materials stammt.
  8. Antriebsvorrichtung nach einem der vorigen Ansprüche 1 bis 5, dadurch gekennzeichnet, dass der Adherenzunterschied zwischen den beiden Zonen (17,18,19) der Leiste (14) von der Zurückstellung einer Zone gegenüber der anderen stammt, um das Zusammmendrücken des Luftreifens (15) des mit der Zone mit einer verminderten Adherenz zusammenwirkenden Rades (13), zu vermindern.
  9. Antriebsvorrichtung nach einem der vorigen Ansprüche, dadurch gekennzeichnet, dass die Reibräder (13) mit einem Luftreifen (15) durch Riemenübertragungen (16) verbunden sind.
