Description

1 2475998

  The present invention relates to a transport installation consisting of wheeled vehicles

  paryie guidelines, and which are entrannées by an engine.

  Vehicles of this type are already known whose supply of the drive motors is ensured by heavy batteries. Such vehicles are heavy and consequently expensive; they need maintenance staff, which makes them expensive because of wages. It is also known to equip vehicles with an expensive pilot installation, mounted a posteriori, and which cooperates with induction loops integrated in the ground. In addition, there are known transport and towed installations comprising chains

  integrated in the soil, and in which

  the vehicle drivers (DE-OS 22 58 018). The disadvantages of this system are the notches

open in the floor of the shed.

  The present invention aims to

  create an inexpensive transport facility, which does not

  is not an obstacle, and whose operation does not incur significant wages, this installation comprising vehicles moving on the ground. For this purpose, the invention relates to an installation characterized in that the steering wheel or wheels are connected via a drawbar or a drawbar, to a steering carriage which moves along a guide rail provided above the vehicle, being connected to a plug device, connected to the loops and connected to the power supply lines of the electric motor or motors. The driven vehicle raises the steering carriage and the latter ensures the guidance of the wheels via the drawbar and the drawbar, in the direction of the guide rail. In this case, the floor of the shed is no longer occupied by expensive installations or annoying grooves; this installation no longer requires

accompanying staff.

  The drawbar is preferably vertical or substantially vertical and is rigidly connected to the front or rear of a rotation bearing, vertical, common, to the drawbar, and ensures proper guidance of the wheels which are connected to the drawbar via the axles and

bearings.

  For differences in resistance

  steering wheels do not have an uneasy effect on the direction of the vehicle, the distance between

  steering wheels is chosen much weaker than the spread-

  fixed wheels. The stablity of the vehicle is not

  unacceptably encumbered by this reduction in the way.

  Each of the steered wheels is connected to an electric motor which drives them; the electric motors of a vehicle have corresponding characteristics that allow differences in rotational speeds without slippage of the wheels on the ground during cornering. Power lines are from

  preferably guided in or on the tie rod.

  According to another characteristic of the invention, the coupling rod is connected by a guide means to the steering carriage, this guide means allowing a rotational movement of the coupling rod with respect to the carriage as well as a change of height between the truck and the ground. The coupling bar is preferably a circular section tube guided in four rollers which are

  mounted in front, behind and on the sides of the front

  and the horizontal axes of the rollers are mounted in bearing blocks of the steering carriage. To compensate for significant differences in height, for example in a rail climb, the coupling rod can be connected to the carriage

  director by a telescopic tube.

  The present invention will be described

  in more detail with the aid of two examples of

  schematically in the accompanying drawings in which - Figure 1 is a side view

  a vehicle and the steering rail.

FIG. 2 is a view from above

of the vehicle.

- Figure 3 shows a way of

  telescopic guide of great length.

  The vehicle 1 comprises rear wheels 2 large spacing, and front wheels 3 whose axes 4 are mounted directly on the drawbar 6 next to the pivot bearing 5. At the end of the drawbar 6 is a coupling rod 7, tubular, fixed vertically and whose upper end is guided between four rollers 8 of a

  directing carriage 10 carried by a guide rail 11. The rollers are mounted in bearing blocks 9 and transmit on the one hand the changes in direction of the guide rail to the drawbar and on the other hand the rollers push the carriage 10 of the vehicle 1, - trained. According to FIG. 3, the rollers 8 are mounted in a telescopic tube 15 articulated on the trolley 10 and rest on the coupling rod in

cavities not shown.

  Each steering wheel 3 is driven by an electric motor 14 whose power supply is

  provided by a current loop 12 carried by the rail

  (guide rail) 11 via a device

  socket 13 carried by the carriage 10 and a

  16 passing through the tubular coupling bar 7.
