Definitions

  • the invention relates to a vehicle wheel of a rigid rim, a flexible tire without air filling and see therebetween, with respect to the radial direction angularly offset, resilient spokes.
  • spoke includes resilient connecting elements between rim and tire
  • rim includes a rigid, usually circular disk-shaped, connected or provided with a hub element, possibly also just a hub.
  • the term “hoop” includes an annular, outboard, flexible element that may be provided with an elastic tread.
  • Width of a wheel and its elements is its dimension in the axial direction. In the wheels considered here, the elements rim or hub, spokes and tires are usually approximately the same width.
  • the invention has for its object to find a wheel of the type mentioned, which does not have the disadvantages of the known wheels of this type.
  • spokes are divided into at least three axially separate groups with alternately oppositely directed angular displacement.
  • the width of the spokes, i. their extent in the axial direction, in the individual groups differed.
  • Fig. 1 is a side view in the axial direction of a wheel according to an embodiment of the invention with six spokes per group
  • FIG. 2 is a perspective view of the embodiment according to FIG. 2
  • Fig. 3 is a perspective view of the embodiment according to Figure 2, but without tires and with three spokes per group
  • Fig. 4 is a perspective view similar to that of Fig. 3, but with six
  • Fig. 5 is a perspective view similar to that of Fig. 3, but with four groups of spokes
  • Fig. 6 is a schematic representation of a in a
  • Fig. 7 is a schematic representation of a in a
  • FIG. 8 shows the situation of the force absorption or the support of a wheel with 12 spokes per group and three or more groups at different angles of rotation.
  • FIG. 9 shows a schematic representation of the effect of radial, tangential and axial forces on the wheel.
  • Figs. 1 and 2 there is an embodiment of the inventive wheel of a rim 1 and a coaxially arranged tire second rim and tires are connected by spokes 3, which are angularly offset with respect to the radial direction. They are arranged so that at their connection with the rim and with the tires the transition runs almost tangentially. For this purpose, they are bent at one end.
  • the spokes are in the form of thin sheets with a small thickness compared to their length and width. They consist of elastic material, such as spring steel.
  • spokes are arranged in three groups. Arranged at a front side of the rim 1 spokes 3 form a first group. The arranged at the opposite end spokes 5, are aligned the same as the spokes 3 of the first group and form a second group. The interposed spokes 4 are oppositely directed as the spokes of the other two groups and form a third group.
  • Fig. 4 In Fig. 4, six spokes are shown in a corresponding representation per group, i. So the number shown in Figs. 1 and 2. However, for clarity, each second spoke is shown in phantom in each group.
  • the spokes of the middle third group are wider than those of the two outer groups.
  • the spokes of the two outer groups have a width of about 60-80% of the width of the spokes of the middle group. This ensures that the mechanical, in particular the elastic properties are the same. are distributed massively or symmetrically on the spokes with different orientation.
  • the length of the spokes can also be varied to influence the properties of the wheel.
  • FIG. 5 shows a version with four groups of spokes 6 - 9, again showing only three spokes per group for the sake of clarity.
  • all spokes are preferably the same width.
  • more spokes are to be provided, i. at least six per group, but depending on the application also significantly more, for example twelve or twenty-four. In general, it will be a number that can be distributed evenly over a range.
  • Figures 6 and 7 show a schematic representation of a section in an axial plane. The spokes are reproduced in a kind of substitute representation as spiral springs in order to illustrate the elastic effect of the spokes.
  • Fig. 8 shows the situation of the power or the support of a wheel with 12 spokes per group and three or more groups at different angles of rotation.
  • the action of a force directed perpendicularly to the tread of the tire would be symmetrical along the tire only at the point of support of the spokes on the tire.
  • the symmetric one remains
  • FIG. 9 shows a schematic representation of the effect of radial, tangential and axial forces on the wheel. As shown in FIG. 9a, with sufficient number of support points as a characteristic, the homogeneous deformation of the tire arises with a constant vertical force acting on the tire.
  • Fig. 9b arises when a torque on the rim a small rotational displacement of the rim relative to the tire. However, this practically does not affect the torque transmission from the rim to the tire.
  • Fig. 9c shows the action of an axial force on the wheel. The displacement of the rim relative to the tire is small. By bending the spokes a high smoothness is achieved.
  • the spokes are connected to the rim and the tire by a variety of bonding techniques, such as welding, gluing, screwing, etc. They can also be integrally formed.
  • Spokes and tires may be made of spring steel with a coating of an elastomer.
  • the wheel described above can be built in any convenient size and used for automobiles, as well as for a variety of other vehicles.
  • the number of spokes can also be varied from group to group if the desired properties would require it.

Abstract

L'invention concerne une roue de véhicule composée d'une jante rigide, d'un bandage flexible sans gonflage pneumatique avec, entre eux, des rayons élastiques décalés angulairement par rapport à la direction radiale. Les rayons sont subdivisés en trois groupes ou plus, séparés les uns des autres dans la direction axiale, présentant alternativement un décalage angulaire orienté dans le sens opposé.
