Definitions

  • the present invention relates generally to wheel arrangements and more particularly to a heavy duty wheel arrangement adapted for carrying out unlimited movement patterns in a horizontal plane with essentially no friction between the wheel and the underlying surface during turning of the wheel.
  • the invention also relates to a vehicle comprising such wheel arrangements.
  • Wheel arrangements are used on most kinds of vehicles, such as cars, lorries, and vehicles adapted for carrying different kinds of loads.
  • the requirements on the wheel arrangements as regards stability, steering capability etc. varies with the vehicle on which the wheels are mounted .
  • FIG. 1 A rectangular chassis with a wheel in each corner as disclosed in this document is shown in Fig. 1.
  • Two diagonally positioned driving wheel arrangements 1 have a special design, are driven and can be turned or swi- veled, and therefore these two drive wheel arrangements are arranged for the driving and controlling or steering function.
  • the remaining two, diagonally positioned non- driving wheels 2 are essentially uniform and are com- posed of conventional caster wheels.
  • a driving wheel arrangement 1 of Fig. 1 will now be described in detail.
  • the driving wheel arrangement is driven by electric motors (not shown) with associated mechanics and elec- tronics, wherein a first motor effects the turning of the wheel about the vertical shaft 20 and a second motor rotates the vertical shaft itself.
  • a first motor effects the turning of the wheel about the vertical shaft 20
  • a second motor rotates the vertical shaft itself.
  • each driving wheel arrangement can be separately controlled, i.e., steered.
  • the positions of the wheel about the vertical shaft and the rotational position of the vertical shaft itself are monitored by means of a respective transducer 13, 23.
  • the motors, transducers etc. are connected to a central unit (not shown) consisting of a microprocessor and associated electronics.
  • the wheel shaft 10 is provided with a first toothed wheel 14 provided with a number of m teeth.
  • the vertical shaft 20 is provided with a second toothed wheel 24 with a number of n teeth.
  • the first and second toothed wheels together form a gear, wherein the ratio m:n determines the gear ratio between the wheel shaft 10 and the vertical drive shaft 20. Due to the shaft configuration, the above described wheel arrangement is not particularly suitable for very heavy loads .
  • An object of the present invention is to provide a wheel arrangement of the kind initially mentioned, which is adapted for heavy loads .
  • the invention is based on the realization that the single wheel of the prior art wheel arrangement can be supplemented by a second wheel provided on the same shaft as the first wheel.
  • the two second wheels are provided at the same distance from the essentially vertical driving shaft, whereby the two wheels are evenly loaded, maximizing the total performance of the wheel arrangement.
  • a vehicle comprising a wheel arrangement according to claim 1.
  • Fig. 1 shows a top view of a rectangular chassis with a wheel in each corner
  • Fig. 2 is an overall view of a prior art wheel arrangement
  • Fig. 3 is a perspective view of a wheel arrangement according to the invention.
  • Fig. 4 is a partially cut away view of the wheel arrangement of Fig. 3;
  • Fig. 5 is an exploded view of the wheel arrangement of Fig. 3.
  • Fig. 6 is a sectional view of the wheel arrangement of Fig. 3.
  • the inventive wheel arrangement comprises two wheels 111 and 112 arranged on a common wheel shaft 110 forming an angle of 90 degrees with a vertical drive shaft 120.
  • the wheels have a rubber portion Ilia and 112a, respectively.
  • the wheels 111, 112 are preferably provided on the common wheel shaft 110 at the same distance from the vertical axis co-axial with the vertical driving shaft 120 in order to get an even load distribution between the two wheels.
  • the common wheel shaft 110 is provided with a first toothed wheel 114 provided with a number of m teeth.
  • the vertical driving shaft 120 is provided with a second toothed wheel 124 with a number of n teeth.
  • the first and second toothed wheels together form a gear, wherein the ratio m:n determines the gear ratio between the wheel shaft 110 and the vertical drive shaft 120.

Abstract

Système de roue comprenant un axe d'entraînement essentiellement vertical (120), une roue essentiellement circulaire (111) montée fixe sur un arbre de roue (110), et une surface de roulement (111a), ledit arbre de roue étant rotatif autour de l'axe d'entraînement vertical, et un engrenage (114, 124) reliant l'arbre et l'axe considérés. La présence d'une seconde roue essentiellement circulaire (112) librement rotative autour de l'arbre de roue (110), sachant que l'axe (120) et l'arbre (110) en question forment un angle de 90 degrés, se traduit par un système de roue approprié aux lourdes charges.
