Abstract:
A wheel axle for a vehicle, having a shaft extending along a main axis, a first protection device and at least one second protection device, each device having a body at least partially surrounding the shaft in a plane perpendicular to the main axis, the body having a first end portion and a second end portion, the end portions being opposite one another along their main axis. The first end portion of the first device at least partially surrounds the second end portion of the second device in a plane perpendicular to the main axis.
Abstract:
A spherical wheel to move a vehicle comprises two caps, the surface of which follows the spherical surface of the wheel, the caps being articulated by means of a pivot link relative to a shaft. The wheel further comprises two casters each arranged in an opening of each of the caps, the opening centered about the axis of the corresponding pivot link, each caster arranged in the extension of the pivot link of the cap concerned. Each caster ensures a rolling at the level of the spherical surface. Radii S of the opening of each cap and r of the corresponding caster are defined to substantially balance forces needed to drive a cap and the corresponding caster when the wheel goes from bearing on the ground on a cap at the edge of the opening to bearing on the ground on the corresponding caster.
Abstract:
Embodiments relate to a motorized skateboard. Embodiments allow users to utilize a power supply, such as a rechargeable battery pack, that is remote with respect to the skateboard. Embodiments can have the battery mounted on, under, partially or wholly enclosed within, and/or integral with the skateboard deck. Embodiments can have a removable and interchangeable motor mount, which attaches to the hanger to align the motor with the drive train. The drive wheel adaptor (hub) allows the user to modify standard skateboard wheels to use as drive wheels for the electric skateboard. The strength of the bond between the drive hub and the wheel enables the skateboard to utilize more torque without failure. Embodiments can allow users to have wiring connections at the front and/or back of the skateboard deck. Board-integrated wiring techniques can also be utilized. The electronics can be attached using brackets that fit the industry standard bolt pattern.
Abstract:
A selectively deployable wheel assembly attachment for attaching to a conventional animal cage, often in pairs, to allow the cage to be rolled when desired without compromising the cage's general stability on a flat surface. The selectively deployable wheel assembly attachment includes a wheel assembly which includes a conventional wheel which is connected to an axle member and a fixed attachment mechanism which includes an attachment plate and an attachment elbow. In some embodiments, the selectively deployable wheel assembly attachment additionally includes an auxiliary support assembly which includes an adjustment plate and an adjustment loop for providing enhanced stability when the wheel assembly is in its deployed position.
Abstract:
An aircraft wheel comprising a rim adapted to receive a tire, and a hub connected to the rim (2) in order to receive bearings for guiding the wheel in rotation about an axis of rotation (X) on an axle of the aircraft. The wheel includes at least one dog (10) that projects laterally from the rim in order to present two parallel faces (11). The dog is pierced by an orifice (12) extending from one face to the other along a generally orthoradial direction (Y).
Abstract:
A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.
Abstract:
A high misalignment wheel drive includes a spline drive with external crown spline for rotation around an axis of the axle shaft and a drive plate for rotation about a drive plate axis, the drive plate including an internal spline for engaging the external crown spline in a pivotable splined connection to allow the spline drive to rotationally drive the drive plate while the drive plate axis is non-aligned with respect to the axle axis by up to an angle α. First and second thrust faces are positioned with respect to the spline drive to rotate with the spline drive and define the angle α between which third and fourth thrust faces, positioned with respect to the drive plate to rotate with the drive plate and for engaging the first and second thrust faces respectively, can move.
Abstract:
A wheel support assembly for use with a vehicle is disclosed that comprises a vehicle mount coupleable to the vehicle, a recess formed in the vehicle mount, a bearing seated at least partially within the recess, an axle engaged with the bearing and extending away from the bearing, and a wheel supported by the axle. To inhibit the transfer of heat from the bearing to the wheel the bearing is in thermal communication with the vehicle mount and the wheel is spaced apart from the bearing along a longitudinal axis of the axle. The vehicle mount is configured as a heat sink such that a larger portion of the heat generated by the bearing is transferred to the heat sink as compared to the portion transferred to the axle.
Abstract:
A cart and track arrangement includes a track unit having a straight track and a curved track, the straight track having an oblique bearing portion, the curved track having a horizontal bearing portion, and a cart having a cart frame and a wheel set, the wheel set having a wheel axle arranged in parallel to the oblique bearing portion of the straight track and a wheel pivotally mounted on the wheel axle, the wheel having a first tread disposed in parallel to the wheel axle for rotatably supporting on the oblique bearing portion of the straight track and a second tread for rotatably supporting on the horizontal bearing portion of the curved track. In an alternate form, the straight track has a horizontal bearing portion, the curved track has an oblique bearing portion, and the wheel has a first tread disposed in parallel to the wheel axle for rotatably supporting on the horizontal bearing portion of the straight track and a second tread for rotatably supporting on the oblique bearing portion of the curved track.
Abstract:
A mobile base for moving on a surface is provided having a driving and steering unit and a plurality of wheel assemblies. The driving and steering unit provides a drive force and a steering force. Each wheel assembly has a wheel assembly axis, and also has a steering column, concentric drive shafts, and two wheels. The concentric drive shafts respond to the drive shaft force, and provide a concentric drive shaft force. The steering column responds to the steering force, and provides a steering column force. The two wheels respond to the steering column force and rotate in the same direction for pivoting the steering column means about the wheel assembly axis. The two wheels respond to the concentric drive shaft force and rotate in the opposite directions to move the mobile base forwards or backwards along the surface.
