A wheel fastening system for a wheeled mobile robot includes a chassis, a motor, a wheel, and a thrust bearing. The motor is disposed in the chassis, and the motor turns a shaft connected to the wheel. The thrust bearing is an interference fit between the wheel and the chassis and provides axial support for the wheel to hold the position of the wheel. The wheeled mobile robot does not deviate from a chosen path during movement.

A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A center-lock attachment arrangement for use in attaching a composite wheel to a mount. TA front element includes an outer engagement surface engaging a center-lock fastening nut and an inner engagement surface engaging an outer side of a central attachment area of the composite wheel. The front element further includes an attachment aperture through which a center-lock fastener is inserted and a plurality of fastener apertures around the attachment. A backing element includes an outer engagement surface facing the mount and an inner engagement surface engaging with an inner side of the central attachment area. The backing element further includes an attachment aperture through which the center-lock fastener is inserted and a plurality of fastener apertures around the attachment aperture. Elongate fasteners received through the aligned apertures of the front and the backing element clamp the front and the backing element over and around the central attachment area.

A wheel loosening sensor (100; 400; 500; 600; 700) configured to detect loosening of a wheel of a vehicle, the wheel loss sensor comprising: a transmitter; a battery (128), wherein the transmitter and the battery are within a water tight housing (102) that is permanently sealed, and wherein at least two electrical terminals (104, 106) are exposed at an exterior of the housing, the transmitter being configured to receive electrical power from the battery and transmit a signal when the at least two electrical terminals are disconnected; an electrically conductive element (108) biased away from the at least two electrical terminals and configured to electrically connect the two electrical terminals when the bias is overcome.

The present invention relates to a safety device (10) for a wheel (11) of a vehicle comprising a rim (12) designed to be fixed to a hub (14) by means of rotational fastening elements (16). The safety device (10) comprises: a plurality of locking elements (30), each element of said plurality of locking elements (30) being suitable for being applied onto one of the rotational fastening elements (16) of the wheel (11) so as to be constrained to rotate together with the rotational fastening element (16); a protection element (20) suitable for being fixed to the rim (12) and comprising a plurality of housing cavities (22); each cavity of said plurality of housing cavities (22) being suitable for receiving one locking element (30); securing means suitable for interfering with the plurality of locking elements (30) to prevent the rotation and/or the extraction of said locking elements (30) from the rotational fastening elements (16). In accordance with the invention the securing means comprising a gripping element (40) suitable for being inserted inside a seat (50) so as to radially engage each element of said plurality of locking elements (30), thereby preventing said locking element (30) from being extracted from the corresponding rotational fastening element (16) and from coming out of its housing cavity (22).

The present embodiments provide a mobile medical device with at least one motor-driven wheel. The mobile medical device is movable on the at least one wheel. The motor-driven wheel is arranged on a hub assigned to the motor-driven wheel. The motor-driven wheel is reversibly removable from the hub and is pluggable back onto the hub manually and without aids. The present embodiments provide that the motor-driven wheel may be removed rapidly manually and without additional aids.

Disclosed is a method of forming a wheel assembly consisting of a wheel portion and a cover portion. The method includes handling the wheel portion from dunnage to a work cell with an outboard face of the wheel portion facing away from a supporting surface. Next, determining a planar position and a rotational position of wheel portion and retrieving the cover portion. The method proceeds with applying an adhesive to at least one of the back side of the cover portion and the outboard face of the wheel portion. Then, aligning the cover portion with the wheel portion utilizing the planar position and the rotational position. The next step is engaging the cover portion and the wheel portion with one another and maintaining the wheel portion in engagement with the cover portion for a predetermined amount of time with a predetermined amount of pressure to form the wheel assembly.
