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.

A wheel hub for a utility vehicle includes a brake element abutment surface against which a brake element bears in an installed state, and a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and/or a receiving region for a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state.

Bicycle hub includes a shell rotatably supported relative to a hub axle, a rotor rotatably supported by two rotor bearings, and a freewheel device having two interacting freewheel components: a hub-side freewheel component and a rotor-side freewheel component. The freewheel components each include axial engagement elements and are axially movable relative to one another between a freewheel position and an engaging, driving torque position. The hub-side freewheel component includes a threaded axial body section and is screwed into the hub shell. The hub-side freewheel component has an axial, annular surface on which the axial engagement elements are configured. The rolling members of a hub bearing show a defined accommodation inside the hub-side freewheel component to support the shell relative to the hub axle. The hub-side freewheel component includes a tool contour which couples to an adapted tool for releasing the screw connection of the hub-side freewheel component with the shell.

An axle assembly, including: an axle sleeve with first and second end faces, an opening, and a first engagement surface; a control shaft with an engagement end, a control end, and a second engagement surface. The control shaft overlaps the opening and is axially displaceable in extending and retracting directions. The control shaft is rotatable relative to the axle sleeve between: (i) a first orientation where the control shaft is retained to the axle sleeve by an overlie engagement between the first and second engagement surfaces to restrict the axial displacement of the control shaft in the retracting direction at a first axial position; and (ii) a second orientation circumferentially offset from the first orientation such that the first and second engagement surfaces are not overlying and the control shaft may be axially displaced in the retracting direction relative to the first axial position.

A wheel hub bearing for motor vehicles, comprising a hub and a bearing unit in turn comprising a radially outer ring, at least one radially inner ring, at least one crown of rolling bodies between the radially outer ring and the radially inner ring, whereas the hub has a radial stiffening. The radial stiffening of the hub has a misalignment (d) respect to a seat, i.e. a distance between a centerline axis (Y) of the seat of the radially inner ring on the hub and a centerline (Z) of the radial stiffening less than or equal to 25% of a length (l) of the seat.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A hub cap assembly includes a disc having a top surface and a bottom surface. A rim extends from the bottom surface. The hub cap assembly also includes at least one tire stem port disposed on the disc. Moreover, the rim comprises a cavity that receives balance media. In some embodiments, the hub cap assembly further comprises cooling fins, e.g., disposed about a circumference of the top surface. The cooling fins can direct cooling air to a corresponding tire, e.g., to cool a bead of the tire.

A fastener retainer includes at least one fastener cap and a hub. Each fastener cap can include a stop channel that encircles a bottom portion of a housing of the fastener cap, a base with cog members that encircle the housing, or a combination thereof. The hub has at least one port therein, where each port is associated with a corresponding fastener cap. At least one locking member is positioned on the hub. For instance, a locking member can be provided adjacent to each port. In use, each locking member constrains radial movement of a corresponding fastener cap inserted into the associated port, by disposing a projecting member into a space between adjacent cog members on the base of the corresponding fastener cap.

Systems, methods and apparatus for automated vehicle wheel removal and replacement are provided. One system includes a computer system with applications for scheduling the replacement of tires for the vehicle. An electronically controlled lift device and robotic apparatus is configured for interaction with the computer system. The lift device mechanically adjusts arms for placement on lift points of vehicles. The robotic apparatus detects positioning of lug nut configuration for a wheel, removes lug nuts, and then removes the wheel from the wheel hub with gripping arms. The wheel and tire are then handed off to a separate tire changing machine. When a new tire is replaced the robotic apparatus then mounts the wheel to the original wheel hub, and then secures the lug nuts to the lug nut bolts.
