Abstract
A wheel includes a central hub and a flexible rim. A drive band configuration including a plurality of flexible bands extends as spokes from the central hub to the rim. The hub and band configuration cause the rim to flex toward and away from the hub as the wheel moves.
Description
- Wheels and tracks are a primary source of propulsion and/or motion for a variety of vehicles and applications. Conventional wheels and tracks tend to churn the terrain they move over. Wheel designs thus could benefit from a greater capability to adapt to the terrain while maintaining stability and forward progress.
- In the drawings, the same reference numbers and acronyms identify elements or acts with the same or similar functionality for ease of understanding and convenience. To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced.

Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively, unless expressly limited to a single one or multiple ones. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list, unless expressly limited to one or the other.
- Embodiments of a wheel are described, having a load-bearing (central) axis that shifts horizontally in a uniform horizontal plane as it moves across the terrain. The wheel includes a central hub and a flexible rim. A drive band configuration for the wheel includes flexible bands extending as spokes from the central hub to the rim. The hub and band configuration are configured to cause the rim to flex toward and away from the hub as the wheel moves. The wheel thus tends to unfold over the terrain, rather than churn the terrain as would a conventional wheel.

FIG. 1 illustrates atread 104 andrim 106 that form part of a terrain adaptable wheel.Axle mounts 102 may be attached to therim 106, for example using mounting holes 108 (e.g., via machine screws through the mounting holes). Thetread 104 is illustrated as a caterpillar type, but may in fact be any tread suitable to the vehicle and the terrain. Therim 106 may be metal, plastic, or other suitable materials. Likewise, thetread 104 may be rubber, metal, plastic, or any suitable material.Multiple axle mounts 102 may be fixed to therim 106 at multiple locations. The ends of therim 106 are illustrated with a slight gap between them, but would typically be joined together. In some designs therim 106 may be constructed using two strips of clock spring, fused to a single strip of rubber tire. - Typically, the
axle mounts 102 will be spaced at equal intervals around the circumference of therim 106. Embodiments including four and sixaxle mounts 102 will be described, although other numbers of axis mounts are also possible depending upon requirements of the particular implementation. -
FIG. 2 illustrates a configuration ofdrive bands 210 that may be coupled to theaxle mounts 102. Thedrive band configuration 210 is comprised ofmultiple drive bands 204. Eachdrive band 204 may be formed to flex along a long axis of theband 204 and may be substantially rigid to both sheer and twisting force along axes perpendicular to the long axis. Example materials for theband 204 are carbon steel, stainless steel, other metals and alloys, and plastic. Thebands 204 are joined together at eachend using couplers 202. Eachcoupler 202 couples a joint of theband configuration 210 to aaxis mount 102 via an insertedaxle 208. Theaxle 208 is inserted through thecoupler 202 and through theaxle mounts 102 on either end of theaxle 208. A flexible cover 206 (e.g., a cylindrical polyethylene cover) may be fitted over eachcoupler 202 to reduce friction of thecoupler 202 against the axle mounts 102 (give example materials for cover 206). Before inserting theaxle 208, thecoupler 202 is rotated so that once theaxle 208 is inserted, agap 212 in thecoupler 202 is rotated 180 degrees from agap 214 in theaxle 208. This secures the joint betweendrive bands 204 and also allows for some limited motion of the joint within thecoupler 202 once it is coupled to theaxis mount 202 during rotation of the wheel. - One design includes a drive band configuration constructed from four bands joined at their ends into a closed four-sided periphery. Another design includes a drive band configuration constructed from six bands joined at their ends into a closed six-sided periphery. Designs including n numbers of bands formed into closed n-sided peripheries (eight, ten, etc.) are also possible.

FIG. 3 illustrates construction of awheel hub 310. Thewheel hub 310 is constructed from a plurality ofhub components 302.Hub components 302 are symmetrically positioned around acenter axle 308. Eachhub component 302 may compriseends 304 having a diameter (circumference) that is larger in relation to an inner circumference of thehub component 302. In some designs (e.g., four spoke designs), theends 304 are separate elements rotationally coupled thehub component 302. In these designs, as therim 106 moves inward toward thehub 310, it contacts theends 304 of thehub components 302, and theends 304 rotate against therim 106 as the wheel turns. Theends 304 rotate against therim 106 in an opposite direction of rotation of theinner diameter 314 against thebands 204. This provides stability to theflexible rim 106 without decreasing terrain flexibility. Thus eachhub component 302, as a unit including itsends 304, simultaneously rotates both clockwise and counterclockwise as the wheel turns. - The
band configuration 210 is compressed inwardly near the center of eachband 204 and compressed to fit between thecenter axle 308 and each of thehub components 302. The result is that each spoke from thehub 310 to therim 106 comprises twobands 204 pressed together.Couplers 306 are fitted over both ends of thehub 310 and retain theband configuration 210 within thehub 310 and retain thehub components 302 in a symmetrical configuration. Power from a drive axle (e.g. axle 308) may be transferred to thehub 310 via thecouplers 306 in some designs. - In some implementations, particularly those that use a coordination gear on the
center axle 308, some hub components have a firstinner circumference 314, and others have a second, smaller circumference (refer toFIGS. 7 and 8 ). The smaller circumference components are used as spacers to limit therim 106 minimal distance from thecenter axle 308 as the wheel turns and to hold thebands 402 snug withcomponent 714 andgear 406. -
FIG. 4 illustrates acoordination gear 406 that may be fitted to thecentral axle 308. Thegear 406 coordinates motion of thebands 402. Eachband 402 of theband configuration 210 may comprise agear track 404 to mate with teeth of thecoordination gear 406. In models employing acoordination gear 406, each spoke from thehub 310 to therim 106 may comprise only asingle band 402. Thegear 406 rotates freely upon the outside of thecentral axle 308 of the wheel, coordination motion of thebands 402. -
FIG. 5 illustrates a completed wheel with fourhub components 302. Thebands 204 are compressed between thecentral axle 308 and thehub components 302. Each band is coupled to therim 106 by axle mounts 102. As the wheel turns, the ends of thebands 204 pivot around theaxis 208 which couples thebands 204 to the axle mounts 102. Thebands 204 are extended away from thehub 310 or are drawn toward thehub 310, depending on the position of the wheel, giving therim 106 and tread 104 a peripheral shape that varies according to the position of the wheel and the topography under the wheel. Therim 106 and tread 104 yield and flex according to the terrain, thus shifting mass of the wheel and any associated vehicle more directly over a force normal to the surface being traversed. In this manner, the wheel adapts efficiently to the terrain it is traversing. - A wheel employing a hub design in accordance with these features and principles swivels between a plurality (e.g., two) pivot points of the
rim 106 as it rotates. The hub oscillates between the ends of the flexible spokes. Each spoke exhibits a cycle of advancing forward of the hub, receding inward toward the hub, and advancing rearward from the hub. The spokes act in unison to deflect the rim in a manner that contributes to gripping the terrain. - In the case of a four-spoke wheel, the bottom spoke, orthogonal to the ground, recedes inward towards the hub. This causes the top spoke to also recede inward. The other two spokes (horizontally positioned) advance outward providing indirect load-support for the hub.
- The four-spoke wheel design employs
hub components 302 comprising an inner diameter (circumference 314) and a larger,outer diameter 304 that rotates independently of theinner diameter 314. Theouter diameter 304 of thecomponents 302 may rotate against therim 106 as the wheel turns, in an opposite direction of rotation as the rotation of theinner diameter 314. Thecomponents 302 may be constructed from an inner rotating member with washers rotationally coupled to the ends. - The particulars of the motion and shape of the rim may vary between designs that employ the features and principles described herein, depending upon design details of the implementation and components.
-
FIG. 6 illustrates a wheel having sixhub components 302 and utilizing sixbands 204. As the wheel turns, the relative distance of therim 106 from thecentral axle 308 varies according to the topography of the surface. The wheel's mass is efficiently shifted more directly over the force normal to the surface being traversed. - The central bottom spoke recedes inward which causes the two adjacent spokes to advance outward at an acute angle to the terrain. This deflection results in the hub being supported by three spokes and not just a single spoke, as is the case of a four-spoke wheel.
- The particulars of the motion and shape of the rim may vary between designs that employ the features and principles described herein, depending upon design details of the implementation and components.
- Designs comprising six, eight, and higher numbers of spokes need not comprise
hub components 302 with a larger, independently-rotating outer diameter (as do certain four spoke designs, e.g.FIG. 5 ). Two spokes adjacent to the bottom, central, orthogonal spoke advance outward at an acute angle to the terrain during rotation, maintaining the hub is in a state of equilibrium, balanced by opposing forces of the three supporting spokes. In these designs, thehub components 302 do not ride upon (rotate against) therim 106 of the wheel. -
FIG. 7 illustrates a gear coordinated six spoke hub design. The hub comprisesbands 402 comprising gear tracks, as illustrated, for example inFIG. 4 . Agear 406 coordinates motion of thebands 402. Each end of aband 402 forms a spoke of the hub. Thus, three bands are sufficient to construct a six-spoke hub in the gear coordinated design.Bands 402 ride upon anouter circumference 714 ofhub components 702. Theouter circumference 714 ofhub components 702 allows the gear tracked band to tightlyarc component 702.Couplers 710 prevents lateral motion of thebands 402. -
Spacer hub components 708 are provided to fit in a space between the largerdiameter hub components 702 when the hub is assembled.Spacers 708 fill in these gaps and retain thebands 402 in the hub and against thegear 406.Couplers 710 may be employed to secure and properly orient the hub components in relation to one another, serving a similar purpose of acomponent 306 inFIG. 3 .Couplers 710 may also transfer power from a drive axle (e.g., 308) to the hub. - The
spacers 708 do not necessarily have a smaller diameter than theinner circumference 712 orouter circumference 714 of thehub components 702. Rather, thespacers 708 has a diameter selected to fit snugly between thebands 402 and thegear 406. For example, the circumference of thespacers 708 may be equal to theinner circumference 712 of thehub components 702 in some designs, or even larger in circumference depending on the configuration of thehub components 702. -
FIG. 8 illustrates a hybrid hub design employing bands with gear tracks and bands without gear tracks. Elements of this hybrid model which are not essential to the description are omitted from the drawing for clarity. The hybrid model may achieve benefits of both the model ofFIG. 3 . and the gear coordinated model ofFIG. 7 . The hybrid model comprisesbands 402 with gear tracks, andsmooth bands 204 lacking gear tracks. Thebands 402 arc theouter circumference 714 of thehub components 702. Thebands 204 arc the circumference of thespacer hub components 708. Each spoke of the hub comprises a portion of aband 402 and a portion of aband 204. This makes the spokes stronger while still providing for power transfer to the wheel rim usingdrive gear 406. Hybrid implementations comprise two bands per spoke (one gear tracked band, one smooth band). The gear trackedband 402 engages thegear 406. Thesmooth bands 204 do not engage thegear 406 but instead arc thespacer hub components 708. Thespacer hub components 708 are sized to prevent thesmooth bands 204 from engaging thegear 406. The gear trackedbands 402 coordinate motion of the spokes, while thesmooth bands 204 eliminate chatter and add rigidity to the spokes. The spokes may attach to the rim mounts 202 where the ends ofbands FIGS. 1 & 2 . - The performance of a wheel employing designs in accordance with the described principles/features may be adjusted by varying the “true circumference” of the wheel. Extending the circumference of the wheel by 4-10% beyond the “true circumference” may flatten the bottom side of the wheel, increasing its grip upon the terrain and its ability to roll smoother upon flat, hard surfaces. The “true circumference” is calculated from the diameter measured from center of the wheel hub to the inside surface of the rim.
- Uses of the rims/wheels in accordance with the described principles/features include, by way of example, tracked vehicles, steep climbing vehicles, rough or multi-terrain vehicles (e.g., military, amphibious, police, scientific), and robotic vehicles.
- Table 1 provides a comparison of implementations including only gear track bands (A), only smooth bands (B), and both gear track and smooth bands (C). Each hub design comprises six spokes. Of course, other hub designs along the same principles may include a different number of spokes.

Based on the hub size and number of spokes, a size of the hub components is determined to pressure fit against the compressed band configuration while encircling the center axle.
- As previously noted, in implementations that utilize a coordination gear and bands with gear tracks, a different sizing may be utilized for the hub components. For example, for a six spoke design, three hub components may have a first diameter, and three hub components may utilize a smaller or different diameter. Spacer components of a different diameter may act to keep the gear engaged against the gear tracks on the bands and/or to maintain contact between the bands and the various hub components, while maintaining a consistent minimum distance between the
rim 106 and the central axle (i.e., acting as spacers). - The hub components may be formed from a single piece of molded or milled material, or assembled from multiple components (e.g., one component for the band roller, others for the ends that roll against the wheel rim). The couplers and central axle may be a single piece, or assembled from multiple components. The hub perimeter may have a non-circular cross section (e.g., square, hexagonal, octagonal, etc). The hub components may be implemented as ball or roller bearings, with or without an extended inner ring.
- Particular embodiments of a wheel utilizing certain mechanical features/principles have been described. Variations of the described embodiments utilizing these or similar features and principles will now be apparent to those having skill in the art in light of this disclosure. The range of wheel designs that the inventor has conceived is not limited to the disclosed embodiments, but to all designs that utilize the features and principles herein disclosed, and as set forth in the claims.
