  • Patent number: 10414215
    Abstract: A tire pressure controlling device for a tire of a vehicle wheel filled with compressed air, includes a control valve unit for filling the tire with compressed air and/or venting compressed air therefrom. The control valve unit is supplied from a compressor for generating the tire filling pressure. The compressor for compressing air drawn in from the atmosphere is driven by the mechanical rotary movement of the vehicle wheel, as a transmission disposed therebetween transmits the rotary driving movement of the vehicle wheel to the drive shaft of the compressor unit.

  • Patent number: 10358005
    Abstract: Systems, methods, and computer-readable storage media are arranged in connection with gravity-driven pumps configured in tires, as well as various supporting concepts, mechanisms, and approaches. As a tire rotates around an axle, the pull of gravity varies for a given point on the tire. While gravity is always pulling ‘down’, the force relative to a fixed point on the tire changes. Gravity-driven pumps exploit these changes in gravitational force to do work. The work can be driving a pump, or generating electrical power to drive a traditional electric pump or other electrical components. A gravity-driven pump is different from an automatic pump that operates using centrifugal force due to rotation of a tire. Automatic, gravity-driven pumps can be used to inflate tires to offset the natural gas leakage of modern tires, and can maintain tire pressure and inflation within a desired or optimal range.

  • Publication number: 20120234447
    Abstract: An automatic tire inflation system including an air pump, a pressure sensor, a microprocessor and a rechargeable battery power supply all housed in a water resistant housing. The housing conforms to the diameter of the rim of a standard vehicle tire and is held to the tire by rim retaining fingers. A recharging jack is mounted inside the housing and is accessed through an aperture on the housing which is sealed by a removable waterproof cover. The microprocessor monitors air tire pressure being sent from the pressure sensor and activates the air pump when the pressure is determined to be too low by the microprocessor. The air pump turns off when the air tire pressure reaches a predetermined set point. The rechargeable battery is recharged by a standard charging device attached by a plug to the recharging jack. Similar automatic tire inflation systems can be mounted to each tire of the vehicle.

  • Patent number: 8123494
    Abstract: A wheel-supporting roller-bearing unit with air compressor that is compact and capable of keeping resistance against the rotation of the hub 4c low while at the same time maintaining good balance, and when necessary, is capable of obtaining compressed air having sufficient pressure regardless of the traveling speed of the vehicle. A plurality of cylinder holes 53 are located at a plurality of locations that are evenly spaced around the circumferential direction on the inside of a cylinder block 50 that is connected and fastened to the inside end section in the axial direction of the hub 4c. Pistons 54 fit inside these cylinder holes 53 and are moved back and forth by a piston-drive mechanism 62 as the cylinder block 50 rotates. The air compressor 2c is a reciprocating-piston compressor, so it is possible to obtain the required air pressure regardless of rpm.

  • Patent number: 8087439
    Abstract: This wheel has features allowing both integrated and non-integrated Central Tire Inflation (CTI) systems to be installed, without the need for a specialized manifold, adapter, or unique wheel to accommodate each specific system. Thus, a single, light-weight wheel in accordance with this invention can accept either non-integrated or integrated CTI valves, allowing the wheels of the invention to be used on newer vehicles with integrated CTI systems, as well as on older vehicles with non-integrated (external) CTI systems. In addition, a wheel with both integrated and non-integrated Central Tire Inflation (CTI) systems is much simpler to assemble since the valve mounts directly to the wheel and no brackets are required, unlike prior two-piece bolt-together wheels.

  • Patent number: 7784513
    Abstract: A device for maintaining a desired inflation pressure within a tire mounted on a wheel of a vehicle which includes a microcompressor having a flexible compression chamber and a magnetic element not on the wheel. As the compressor passes the magnet each wheel revolution, a small amount of atmospheric air is pumped into the tire, if needed. The magnet and the compressor need no other contact with the vehicle or the wheel and require no energy source on the wheel. An alternative embodiment uses an electrical coil on the wheel to pass the magnet inducing a voltage that drives a compressor on the wheel. As the coil passes the electromagnet it provides a split transformer that transfers electrical power to the wheel and permits two-way pulse data communication between the wheel and the vehicle.

  • Patent number: 7526952
    Abstract: A tire wheel having an air pressure regulator capable of immediately varying the air pressure of a tire of a vehicle in accordance with external environments is disclosed. To regulate the internal air pressure of the tire, the air pressure regulator includes a vacuum chamber, an ultra-high pressure chamber, and a generator for generating electricity to drive the air pressure regulator. The air pressure regulator is actuated by a force generated when the tire is pressed by the ground during the rolling of the tire. An electronic controller collects data obtained by various sensors, and communicates with a central processing unit in a wireless manner. The central processing unit processes the collected data. The driver can monitor all tire states, and can set a control mode associated with the air pressure of the tire. It is possible to deflate the tire in a moment in accordance with the vacuum pressure of the vacuum chamber.
