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.

System for inflating a tire of a wheel, configured to be build inside or onto a hub of a vehicle, comprising a stationary section and a rotary section wherein the stationary section comprises a first clutch part, wherein the rotary section comprises a second clutch part, configured to selectively engage the first clutch part; an actuator, a driving unit, a pumping unit, and a housing, for housing at least the pumping unit, wherein the housing and the pumping unit are arranged to move together with movement of a wheel, in particular rotate together with the wheel.

All tire systems, including tire systems that include self-inflating devices, need to have the ability to regularly and reliably monitor and report vehicle and tire conditions for safety reasons. For a self-inflating tire, this can be accomplished by monitoring the operation of the self-inflation system, and assessing if it is consistent with a tire in good condition.

A device for transport of air in the tire P or close to it consisting of a chamber K in the shape of a hollow compressible channel, placed along at least a part of the tire perimeter, characterized by the fact that a ring OK is placed at the inner side of the chamber K with the distance of its outer side from the tire axis of rotation equal to 1 to 1.1 multiple of the distance of the bottom side of the chamber K from the axis of rotation of the tire P.

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.

A compressor unit (38) for supplying pressurized medium to a tire mounted on a vehicle wheel rim (34), having a compressor (58) for exerting pressure on a fluid medium that is to be conveyed into the tire. The compressor unit (38) is dimensioned to be accommodated in a center bore (44) of the vehicle wheel rim (34) when the vehicle wheel rim (34) is in the mounted state on a wheel hub (62); and the compressor (58) can be driven by a drive unit (56) positioned in the vicinity of the center bore (44) of the vehicle wheel rim (34). The compressor unit (38) is usable with a vehicle wheel rim (34) having a pressurized medium supply device (22) for a tire that is mounted on the vehicle wheel rim (34), as well as a vehicle having a vehicle wheel that includes such a vehicle wheel rim (34).

Environmentally friendly electrical vehicles are presented. The electrical vehicles include electrical low speed vehicles (LSVs) that may use sensed location data to obtain one or more operational profiles. The operational profiles may govern the behavior of the LSV in a specific environment, area, or zone to ensure the LSV reduces its impact on the local terrain. The LSV may leverage locally sensed data to form a local context in which the LSV is operating. The LSV's vehicular controller may refine the operational parameters of the operational profile to ensure smooth operation based on local conditions from the local context.

A tire air filling device according to one embodiment includes: a cylinder; a weight which has an air flow hole and which receives a centrifugal force to move and cause air to be supplied to an inside of a tire; a first sealing member; a first spring; a first support portion; and a backflow prevention valve. The backflow prevention valve includes a slide member that slides in the air flow hole in an axial direction, a second spring that biases the slide member to a side opposite the tire, a second support portion that supports an end portion of the second spring in the axial direction; and a second sealing member interposed between an inner surface of the air flow hole and the slide member. The slide member, the second spring, and the second support portion are disposed inside the weight.
