Abstract:
An omni-wheel according to the present invention has a continuous axle and roller design enabling robust durability and ease of manufacturing. The omni-wheel hub is designed to be injection moldable in two halves which constrain the continuous axle or be 3D printed as one piece with integral rollers and continuous axle which controllably deform to reduce vibration and under sudden physical shock, deform to protect structural integrity.
Abstract:
An omnidirectional wheel including a rim with at least one plate member and a means of attaching the wheel to a vehicle; a plurality of rollers comprising at least two toroidal rows of rollers disposed around the rim for mounting a tire; and a means of actuating the tire around its axis, defined, for example, by the never-ending torus axial member of the tire, whereby, when the wheel is engaging the ground, the tire rolling on the rim causes a side movement of the wheel, parallel to the wheel axis, in a plan orthogonal to the normal plan of rotation of the wheel when attached to the vehicle. A tire having a never-ending torus axial member, a helical bearing member, and a resilient toroidal shape is also provided.
Abstract:
Die Erfindung betrifft ein Mecanumrad mit einer eine Mehrzahl von in einer Umfangsrichtung nebeneinander angeordneten, jeweils um eine winklig zu einer ersten Felgendrehachse (24) angeordnete Rollendrehachse (38) verdrehbar gelagerte Rollen (4) tragenden ersten Felge (2), wobei eine über eine gemeinsame Antriebswelle (33) mit der ersten Felge (2) antreibbare, eine Mehrzahl von in einer Umfangsrichtung nebeneinander angeordneten, jeweils um eine winklig zu einer zweiten Felgendrehachse (25) angeordnete Rollendrehachse (38) verdrehbar gelagerte Rollen (4) tragende zweite Felge (3), der mit der ersten Felge (2) über Dämpfungsmittel (7) verbunden ist, die eine begrenzte Relativbewegung der ersten und der zweiten Felge (3) zueinander zulassend ausgebildet ist. Erfindungsgemäß ist vorgesehen, dass die Dämpfungsmittel (7) eine gedämpfte, begrenzte Relativbewegung zwischen der ersten und der zweiten Felge (2, 3) in Umfangsrichtung und/oder senkrecht zu einer Mecanumraddrechachse (9) und/oder senkrecht zu der ersten und/oder zu der zweiten Felgendrehachse (25) und/oder kippwinklig zueinander zulassend ausgebildet sind.

Abstract:
The turning device described herein presents an alternative to the conventional wheel and associated steering mechanism. The turning device has a surface gripping member (23) which contacts a surface in use. The frictional and contact forces between the surface gripping member (23) and the surface can move an object to which the turning device is attached relative to the surface. Alternatively, the turning device may remain in situ and act on a surface of an object which is required to be deflected. Only a portion (65) of the surface gripping member (23) need be laterally deflected to turn an object. A deflection means (71) is provided in order to deflect the surface gripping member (23). The turning device has applications in cars, golf buggies, factory machinery such as forklift trucks or transportation devices and luggage or parcel sorting devices.
Abstract:
A main ellipsoidal drive element is provided including a buoyant internal chamber. The main ellipsoidal drive element defines a mam ellipsoid axis, a minor ellipsoid plane, a first ellipsoid end portion, a second ellipsoid end portion, and an outer ellipsoid surface, A drive engagement element is mounted to the first ellipsoid end portion and selectively transfers rotational drive to the main ellipsoidal drive element around the main ellipsoid axis, A plurality of roller elements are mounted around a minor ellipsoid periphery of the main ellipsoidal element. Each of the roller elements are orientated to provide friction reduced rolling in a main ellipsoid axis direction and traction perpendicular to the main ellipsoid axis direction.
