Definitions

  • the present invention relates to a wheel, in particular a vehicle wheel.
  • Various wheels are known for driving vehicles. Vehicles using known wheels have limited flotation.
  • the cross-country ability of a vehicle is usually understood as its ability to move on low-quality roads and off the road network, as well as to overcome obstacles.
  • caterpillar propellers are often used, containing a caterpillar belt moved by a driving wheel along a system of rollers.
  • the track is elongated to provide a greater contact area with the surface on which it travels. This is due to the low specific pressure on this surface and, accordingly, high permeability.
  • the disadvantage of the tracked mover is its low operational reliability due to the complexity of the design and rapid wear of the rubbing parts.
  • Wheels with a variety of spoke configurations are also known. Typically, these wheels are designed to absorb shock and vibration when the vehicle is moving. Such solutions practically do not bring improvements in the cross-country ability of the vehicle.
  • the spoke parts attached to the rim are telescopic.
  • the task of the known wheel is to absorb shock and vibration during vehicle movement. At the same time, the passability of such a vehicle remains limited.
  • there is an obvious need for further improvement of the known wheels in particular for improving the passability of vehicles using such wheels.
  • the object of the present invention is to provide a wheel that provides increased permeability to the vehicle in which it is used.
  • each spoke consists of at least two parts connected to each other with the ability to rotate with respect to each other, and one of these parts is connected with the possibility of rotation to the hub , and the other is connected with the possibility of rotation to the rim, while the rim has a limited flexibility in the plane of the wheel, and the distance between the wheel axis and the rim is variable around the wheel circumference.
  • the proposed wheel under the action of its own weight and the weight of a vehicle using such a wheel, acquires an elongated shape similar to that of a caterpillar track.
  • curved, essentially semicircular, sections of the rim are located in the front and rear parts of the wheel in the direction of travel.
  • the curvature of the rim of such a wheel in its upper and lower parts is usually close to zero, i.e. the wheel rim has substantially straight sections at these locations.
  • the proposed wheel provides a technical result, which consists in increasing the permeability.
  • Parts of the spoke can be connected to each other with the possibility of limited rotation with respect to each other. This can be achieved, for example, by installing a stop bar on one of the spoke parts. In this case, when the spoke portions are pivoted with respect to each other after the predetermined pivot angle has been reached, further pivoting is prevented by the abutment of the other spoke portion against the stopper bar, as described in more detail below. Due to the limitation of the rotation of the spoke parts with respect to each other, the structure of the spoke and rim parts acquires rigidity in those spoke positions in which the spoke parts are rotated with respect to each other at a minimum predetermined angle. Thus, the wheel in this version has increased strength. It should be obvious to a person skilled in the art that limiting the rotation of the spoke parts with respect to each other can be achieved in other ways, for example, using a hinge of an appropriate design with an integrated stop.
  • One end of the rod can be pivotally attached to each spoke at the junction of its parts, and the other end of this rod can be pivotally attached to the rim at a certain circumferential distance from the point of attachment of the spoke to the rim. This solution increases the stability of the wheel during rotation.
  • the rod and the spoke portion attached to the rim are identical and form a Y-configuration with the spoke portion attached to the hub.
  • the distance between the points of attachment of the rod and the spoke to the rim can be equal to the total length of the rod and the part of the spoke attached to the rim.
  • the end of the spoke and the corresponding rod attached to the rim diverge to the maximum distance, essentially forming a flat angle. Due to the impossibility of increasing this distance, further rotation of the spoke parts in relation to each other is not possible, so that other limiting means, such as stop bars, become unnecessary.
  • the spoke parts and the rod are mainly in tension, so the needles and rods can be flexible.
  • the end of the spoke and the corresponding rod attached to the rim converge again and, accordingly, the angle between them decreases.
  • the spoke parts and / or the rod can be made in the form of rods or elongated plates, and the joints of these rods or elongated plates with the rim, hub and between themselves can be hinged or flexible.
  • the ability of the spokes and rods to withstand compressive loads is absent, because Despite the rigidity of the rods themselves or the elongated plates, the hinges provide flexibility and prevent the spoke with the rod attached to it from forming a rigid structure.
  • the rim in the proposed wheel can be made of segments, with each two adjacent segments connected to each other with the possibility of limited rotation with respect to each other. Thus, limited wheel compliance is ensured.
  • the rim segments can be pivotally connected. Also, the rim segments can be connected flexibly, for example by means of flexible links.
  • the angle of rotation of each two adjacent segments can be limited, for example, in the range from - 360 / N to 360 / N, where N is a number from 10 to the number of rim segments.
  • N is a number from 10 to the number of rim segments.
  • the hub of the proposed wheel can be made with the possibility of mounting the wheel on a standard vehicle axis, and for this purpose, corresponding holes can be made in the hub.
  • An embodiment of the present invention is also possible, in which the proposed wheel is mounted on a standard vehicle wheel.
  • the standard vehicle wheel is entirely used as a hub, or the proposed wheel is rigidly attached to the standard vehicle wheel.
  • This solution allows the proposed wheel to be used as an attachment in those situations when it is required to increase the cross-country ability of a vehicle, for example, when leaving the road on unstable ground or snow.
  • the rim is continuous, and its limited flexibility is provided due to its structure and / or the material from which it is made.
  • Limited flexibility of the rim can also be achieved when the rim is made of at least one flexible tape on which at least At least on one side, there are persistent protrusions of such a configuration that when a given curvature of the tape is reached, they, closing, prevent further bending of the tape.
  • the wheel When the wheel is wide, i.e. has a certain length in the axial direction, it may contain an additional set of spokes so that the two sets of spokes are axially spaced apart from each other.

Abstract

L'invention porte sur une roue de véhicule comprenant un moyeu, une jante et des rayons, chaque rayon étant constitué d'au moins deux pièces reliées en rotation l'une à l'autre, l'une de ces pièces étant reliée en rotation au moyeu et l'autre reliée en rotation à la jante, tandis que la jante présente une flexibilité limitée dans le plan de la roue, et la distance entre l'axe de la roue et la jante varie en suivant la circonférence de la roue. Etant donnée la flexibilité limitée de la jante, la roue proposée, sous l'influence de son propre poids et du poids du véhicule utilisant une telle roue, acquiert une forme allongée similaire à la forme d'une chenille d'un propulseur à chenilles. Il est également possible de monter la roue de l'invention sur une roue régulière du véhicule.
