Systems and methods for an energy harvester proximate to a rotatable component of a vehicle's wheel are disclosed. In some embodiments, an energy harvester system includes: a plurality of energy harvesting components configured to be coupled to a rotatable component in a ring formation along a circumference of the rotatable component, wherein each of the plurality of energy harvesting components includes: a substrate configured to be attached to a surface of the rotatable component; a piezoelectric component coupled to a surface of the substrate, wherein the piezoelectric component is configured to deform in response to a mechanical strain imparted on the piezoelectric component as the rotatable component rotates and generate an electric signal; and an interconnect coupled to the piezoelectric components and configured to conduct the electric signal from the piezoelectric components to a device coupled to the rotatable component.

A bicycle component includes a hub shell for a wheel of an at least partially muscle-powered bicycle, wherein the hub shell is rotatably supported by at least one bearing device. An adapter unit is disposed on one end of the hub shell. The adapter unit includes an inner stopper having an inner stop face for transferring a clamping force to the bearing device and an outer stopper with an outer stop face transmitting at least part of the clamping force. The adapter unit includes a first and a second stopper component transmitting the clamping force.

A drive device for driving and rotating a wheel includes an axle shaft, a hub to which rotation of the axle shaft is conveyed, a plurality of fasteners for securing the wheel to the hub, a wet brake, a housing, an oil seal, and a cover. The wet brake is configured to restrain the rotation of the axle shaft. The housing accommodates the axle shaft and the wet brake. The oil seal is disposed between the housing and a part of the hub that is disposed inward of the fasteners in a radial direction of the hub. The cover has an annular shape. The cover is disposed in a space formed between the hub and the housing, and is secured to the housing. The cover is configured to cover the plurality of fasteners.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

A powered aircraft wheel is designed to include multiple wheel sections configured to define a cavity within the wheel and to support completely within the wheel cavity an onboard non-engine drive means controllable to move an aircraft autonomously without reliance on aircraft engines during taxi and ground travel. Each part of the powered wheel may be constructed of a material specifically selected to emphasize a functional property of the material that is optimal for the function of the wheel part at a specific location. The selected combination of functionally distinct materials gives the powered aircraft wheel a unique optimal structural and functional capability.

A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.

The invention, in a first variant thereof, relates to a hub for a bicycle wheel with a disc brake. The hub comprises a pin extending along a longitudinal axis (X), a body rotatably mounted on the pin and comprising a coupling portion with a brake disc, a bearing radially interposed between the pin and the body and in axial abutment with the body, a cap associated with a free end portion of the pin and configured to be associated with the frame of the bicycle and a calibrated washer in axial abutment with the pin and one between the cap and the bearing or axially interposed between the bearing and the body. By selecting a calibrated washer of desired thickness, it is possible to precisely position the brake disc with respect to the frame, and thus with respect to the pads associated therewith.

A bearing device for a wheel has a stem shaft of an outer joint member of a constant-velocity universal joint fit and inserted in a hole of a hub wheel, the stem shaft and hub wheel being coupled through an intermediation of a recess-projection fitting structure. Projections extending in an axial direction are provided on one of the stem shaft and an inner diameter surface of the hole of the hub wheel. The projections are press-fit into another of the stem shaft and the inner diameter surface of the hole along the axial direction. Recesses that adhere to and fit the projections are formed in the other. An end on an inboard side of the hub wheel is caulked to an outer diameter side to form a caulking section and preload is applied to a roller bearing by the caulking section.

A half shaft and hub bearing assembly includes a half shaft including a CV joint outer race and a stub axle extending from the CV joint outer race. The CV joint outer race includes a first axial face including an annular groove and the half shaft includes a first chamfered shoulder having a chamfer angle. A hub bearing includes a body having a bore therethrough that receives the stub axle. The body includes a second axial face opposing the first axial face of the CV joint outer race with a gap therebetween and a second chamfered shoulder engaging the first chamfered shoulder. The hub bearing includes a hub flange extending radially from the body. A seal ring is received in the annular groove in the first axial face of the CV joint outer race and the seal ring being disposed against the second axial face of the hub bearing.
