A hub-integrated inflation system which functions to convert relative motion at the wheel end (e.g., between the axle and the hub or wheel) into a pumping motion. The relative motion is then converted into mechanical or electrical energy, which can be used to actuate a pump of an inflator.

The invention relates to a vehicle with a compressor assembly for supplying pressure medium to a tire cavity of a tire of the vehicle wheel mounted on a wheel hub, wherein the wheel hub is mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly is located at or in the wheel hub mount.

A motor vehicle with a compressor assembly for the supply of a pressure medium to a tire cavity of a tire of a motor vehicle. The compressor assembly has a compression chamber which is rotationally fixed in relation to the motor vehicle wheel, and the compression chamber and the tire cavity are connected via a fluidic connection for the conveying of a pressure medium from the compression chamber into the tire cavity. A tire sealing device has a sealant reservoir with a first connection fluidically connected to a tire cavity of a tire of the motor vehicle to be repaired, and a second connection fluidically connected to a pressure medium source secured to the motor vehicle. The sealant is conveyed out of the pressure medium source into the tire cavity of the tire to be repaired by means of the pressure medium.

A wheel-mounted air compression apparatus for maintaining a predetermined inflation pressure of a tire mounted on a wheel of a vehicle and the tire having an inflation port includes a housing defining an air compression chamber and has an air compressor device positioned therein. The apparatus includes a plurality of support legs spaced apart from one another. Each support leg is attached to the housing and extends away therefrom and may include a pair of sleeves that are length-adjustable for mounting to wheels of various sizes. A pressure sensor is situated in the housing and operably connected to the air compressor and to a nozzle for determining a current pressure of air within the tire. A controller or other electronics cause the air compressor to pump air into a tire if the air pressure therein is detected as declining below a predetermined amount.

The invention relates to a compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which can be mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly includes a wheel mount-side transmission component or the hub-side transmission component, which includes a cylindrical cam.

A compressor assembly (10) for supplying pressure medium to a tire cavity (7) of a tire of a vehicle wheel, which can be mounted on a wheel hub (4) that is mounted on a wheel carrier (3) for rotation about an axis of rotation (32). The compressor assembly (10) includes a hub-side compression chamber (16) and a compressor component (18). A pressure medium is conducted into the tire cavity (7) upon being pressurized in the compression chamber (16) by oscillating translational motion of the compressor component (18). The compressor assembly (10) includes a transmission (20) that converts a rotational motion between the wheel carrier side and the wheel hub side into an oscillating translational motion of the compressor component (18) when a hub-side transmission part (24) is in an operating position with a wheel-carrier-side transmission part (26).

The invention relates to a compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which can be mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly includes a wheel mount-side transmission component including a cylindrical cam.

The present invention relates to a vehicle wheel comprising a hub, a rim and an inflatable tyre, in which the hub is situated around a rotation axle of the wheel, a compressor which is situated substantially inside the hub for compressing outside air, provided with an inlet for taking in air at atmospheric pressure and an outlet for delivering air at an increased pressure; a drive for driving the compressor, in which the drive is movable with respect to the rotation axle, in particular rotatable, more particularly rotatable in a direction opposite to that of the hub; an air reservoir for storing the air at increased pressure, in which the air reservoir is situated inside the rim of the wheel; a connection for connecting the outlet of the compressor to the air reservoir of the inflatable tyre of the wheel.

A compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which is mounted on a wheel carrier so as to be rotatable about an axis of rotation. A transmission, preferably a cam mechanism, is equipped, through a cooperation of a wheel mount-side transmission part with a hub-side transmission part, to convert a rotary movement between the wheel mount side and the wheel hub side into an oscillating translatory movement of the compressor component, with the translatory movement of the compressor component extending at least partially, preferably entirely, in a radial direction that is oriented orthogonally to the axis of rotation.

A system for tire inflation including a drive mechanism defining a rotational axis, including an eccentric mass that offsets a center of mass of the drive mechanism from the rotational axis along a radial vector; a pump arranged radially distal the rotational axis of the drive mechanism, including a chamber defining a chamber lumen, and a reciprocating element arranged at least partially within the chamber lumen and translatable along a pump axis; a drive coupler coupled between the drive mechanism at a first position and the reciprocating element at a second position fixed to the reciprocating element; a torque regulation mechanism; and a controller, communicatively coupled to the torque regulation mechanism; wherein the system is operable between at least a first mode and a second mode by the torque regulation mechanism in cooperation with the controller.
