  • the spokes are free to shift slightly within their respective slots, to absorb some of the force, but the bulk of the forces encountered, which will orient vectorially within the structure of the arranged spokes will bias against the various springs.

  • the angular direction of the vectorial force, exerted upon any and all spokes will be applied against the springs and absorbed therein.
  • the nuts can simply be tightened thus compressing the springs, in order to resist the impacting forces, but obviously, when tightened too excessively, may transmit more of the impacting force directly to the wheel and its equipment. And, if the nuts are loosened too extensively, the spokes may have too much freedom to shift within their slots, relative to the hub which will loosely move and sink under a load.
  • the concept of this invention is to provide a series of radially spaced spokes radiating from a hub, and which bias against springs coaxial with the spokes, which are adjustable, for the purpose of absorbing the various forces generated when an impact is encountered by a wheel during usage upon any vehicle or piece of equipment.
  • the forces whether they be radially disposed, perpendicularly disposed, or along any other vector of force, can be absorbed by the various cushioning springs that are built into the structure of this suspension system, and likewise, can cooperate with the various spokes that radiate from the hub, for cushioning against any impact force encountered, and to absorb it from transferring to the vehicle or equipment during usage of a vehicle in which the suspension system of this invention is installed.
  • the invention includes the design of a wheel system, where the rim and tire will move independently of its hub, when a force is encountered. While the various designs and modifications herein are similar, they generally provide for the same desired results, to function as a suspension and shock absorbing system that can absorb vectorial forces.
  • each of these systems incorporates a one piece hub, which will have a number of spokes radiating therefrom, and it can be any number of such spokes, as defined, provided it is at least three in number. Preferably, an odd number of spokes will be used in order to encounter and absorb the vectors of the forces generated within the wheel, during usage. In the preferred embodiment, five of such spokes may be used.
  • nuts are threadily applied onto each of the shaft portions for each spoke to adjust the stiffness of each spring, to increase the magnitude of forces absorbed during impact, and to cushion such forces from being transferred from the wheel, through the vehicle, and to the cargo. It is unique that the wheel resists any and all lateral forces applied to it because the movement is very near the rim, as opposed to the hub, where the forces are at their greatest. Dynamic forces on the wheel will allow the rim and tire to move independently on the hub, and the shock will be absorbed by the compression springs, and the slight radial shifting of the hub and its spokes, relative to the rim. Centrifugal forces generated during rotation of the wheel will cause the rim to center in relation to the hub, with a very quick reaction time to achieve such.
  • FIG. 7 shows an alternate embodiment of the rim where the spoke connects. Similar to FIG. 5, the spoke 8 extends radially outward from the hub towards the rim and includes a washer 10. The spoke approaches the inner surface 4 of the hub and engages a slot 5b.
  • This slot 5b has a generally elongated shape set into the rim and a depth to receive the spoke that allows for clearance when the spoke moves under load.
  • the slot has two opposed ends that taper towards the centerline of the slot. The tapering of the ends increases the points of contact of the spoke with the ends thus reducing noise and impact stresses upon the rim and the spoke. Though tapered ends are shown, alternative shapes for the slot include polygonal, oval, ovoid, and rounded.
  • the washer 10 has a generally square shape while the slot 5a has an elongated rectangular shape recessed into the rim and a depth for receiving the spoke with enough clearance when the spoke moves under load.
  • the length of the slot generally follows the circumference of the rim.
  • the width of the slot matches the length of an edge of the washer.
  • FIG. 9 describes an alternate embodiment of the rim having flat surfaces where the spokes 10 engage the slots 5.
  • the washer travels upon the remaining inner surface of the rim when the spoke moves in response to loads placed upon the hub.
  • the washer maintains its maximum surface area in contact with the rim thus lowering stresses upon the washer.
  • a still further alternate embodiment has the rim formed of two matching halves that assemble similar to FIG. 9 in finished form.
  • This alternate embodiment though has a keyway formed in each slot upon assembly of the halves.
  • the keyway has sufficient depth and width to admit the washer but not the spoke.
  • the keyway is generally tangential to the spoke and serves as a guide for the washer within the rim. In usage, the keyway limits travel of the washer along the length of the slot and prevents pulling out of the washer from the rim when the hub is under load.
  • the internal wheel suspension system with slotted rim is uniquely capable of suspending a hub within a wheel subject to forces from any angle in the plane of the wheel or caster.
  • the internal wheel suspension system with slotted rim and its various components may be manufactured from many materials including but not limited to polymers, rugged plastics, neoprene, nylon, ferrous and non- ferrous metals and their alloys, and composites.

Abstract

L'invention concerne un système de suspension de roue interne et d'amortissement des chocs comprenant un moyeu avec des rayons s'étendant radialement, coopérant avec des ressorts montés de manière axiale, venant en contact avec le moyeu et en contact avec la jante d'une roue. Les rayons sont fixés sur un moyeu monté sur l'essieu du véhicule de manière à permettre une rotation. Lorsqu'une force est exercée, les forces sont amorties par les rayons, les ressorts et les fentes, le moyeu effectuant un mouvement de translation limité dans la jante. Les ressorts sont réglables et polarisés contre la tête des rayons et le moyeu, et amortissent l'impact des forces vectorielles générées par n'importe quel choc.
