An agricultural vehicle is operable in a first state for transport and in a second state for field work and includes a frame supported by a plurality of tires. A processor is operable to receive a signal generated as a result of the agricultural vehicle transitioning from the first state to the second state or from the second state to the first state. A gas system is operable to modify the tire pressure of the plurality of tires of the agricultural vehicle in response to the signal.

A peristaltic pump chamber with shape memory for pressure adjustment in tires is provided and which is part of the tire or is adjacent to the tire wall or is a part of a vehicle wheel, in particular for tires with an inner tube, e.g. bicycle tires.

A gaiter (4) for a lubricated joint (1) comprises a sidewall structure (9) defining an enclosure (5) for receiving a lubricant and a passageway (24) for conveying a gas. In use, the passageway (12) conveys gas in isolation from said enclosure (5). Gaiters (4) in accordance with the invention find application in vehicle central tire inflation systems (CTIS).

A vehicle tire pressure control system includes a road sensor configured to acquire road data regarding a road at an advanced location ahead of a current location of a vehicle; a pressure regulator configured to control the air pressure within a tire of the vehicle during operation of the vehicle; and a controller configured to control operation of the pressure regulator and vary the air pressure within the tire based on the road data.

An example of a vehicle tire gauge system includes a tire pressure monitoring system in a vehicle. A transceiver in the vehicle is for transmitting a tire pressure sensed by the tire pressure monitoring system to a paired wearable device. A tire pressure table is stored in a model of an application having a view on the wearable device. A haptic feedback generator in the wearable device is responsive to the tire pressure reaching a first value, wherein the first value is contained in the tire pressure table.

Rotor with breather and anti-rotation arrangement for tire calibration arrangements that provides a suitable breather of the axle hub, and, in turn, an improved oil retention thus preventing the premature wear of internal pieces and possible accidents during its operation.

A device (10) for providing air under pressure to a rotating pneumatic tire is disclosed. The device comprises a pump (48, 50, 58) which in use rotates with the tire and which provides air under pressure to the tire when the pump is activated. There is a pump drive system for activating the pump upon a loss of pressure in the tire. The pump drive system includes a connecting rod (52) which is rotationally connected to the tire and an eccentric body (32) which rotates with the rod when the pump is inactive. The eccentric body is inhibited from rotating with the rod to activate the pump. Relative rotation between the rod and the eccentric body drives the pump to provide air under pressure to the tire. An electromagnetic clutch is provided which has a first plate (26) which is non-rotatable and a second plate (36) which rotates with the body. The first plate is connected to the second plate electromagnetically when the clutch is engaged to prevent rotation of the second plate and hence of the connecting rod.

Disclosed are a method and/or an apparatus of a foldable-reinstallable wireless warning system for transporting oversize loads. The system includes a transmitter unit, a towing receiver unit, a foldable banner, a battery enclosure, and a set of surface mounted lights. The transmitter unit is configured to transmit an encoded signal. The towing receiver unit is separate from the transmitter unit and is configured to receive and communicate the encoded signal to a radio receiver. The foldable banner has an oversize load warning message printed thereupon. The battery enclosure and the set of surface mounted lights are stitched onto the foldable banner. The radio receiver, a lithium-ion battery and a strobe light controller are housed in the battery enclosure. The set of surface mounted lights includes stop tail turn lights, strobe lights and D.O.T. lights.

The invention concerns a method for managing the load of a vehicle (C) of the type of that equipped with at least one module for transmitting data (110, 120, 130) through radiofrequency signals (F1, F2, F3) and one module for receiving (120, 220) data from the transmission module, said vehicle (C) and the different modules being disposed so that the load, once present, has an impact on the propagation of the radiofrequency signal, remarkable in that it comprises the following operation: detection of the variation of the spectral signature of the signal received (F2′) by the receiving module (120, 220), in order to detect variations, in particular corresponding to the presence and/or absence of a load (600).

The invention also concerns the device enabling said method to be implemented.

Applications: managing the load of a vehicle.
