Abstract: A tire pressure monitoring system transmits wireless signals from an on-vehicle controller to each of tires on a vehicle. Sensor units each measure pressure of the corresponding tire and transmit the measured pressure as a wireless signal. The controller transmits request signals to the sensor units at a specified timing and answer signals containing the measured pressure are returned. Each tire has a tank with a valve, containing a sealing agent. If the controller concludes from the measured pressure that there is a tire failure, a signal is transmitted and the corresponding sensor unit opens the valve to discharge the sealing agent into the interior of the tire to seal its failure. The controller may find a tire failure also based on the speed of change in the tire pressure calculated from the measured pressure even if the measured pressure is within a normal range.

The airbag is inflated with pressurized gas in the event of a tire failure. The inflated bag generally conforms to the inner walls of the tire to support the weight of the vehicle and enable the vehicle to be safely stopped. The bag has wear surfaces composed of durable material such as nylon or Kevlar fibers.

Abstract: A dual-function tire inlet valve mountable on a tire in communication with a compressor in a tire pressure maintenance system is disclosed. The inlet valve has a conduit extending from an ambient air supply to an interior chamber of the tire. A first check valve and a second check valve are positioned within the conduit to define a pump between the first and second check valves. The pump channel is in fluid communication with a compressor in the tire pressure maintenance system. The first check valve opens automatically only when the compressor is active and the tire is rotating about its axis with at least a pre-determined velocity. The second check valve only opens when it is manually actuated. Manually actuating the first check valve opens the second check valve to permit manual adjustment of the tire pressure.

Abstract: An electromechanical apparatus suitable for mounting on a vehicle wheel power for generating telemetry relating to the wheel including tire temperature and pressure. The apparatus includes a pendulum mounted to rotate freely relative to the vehicle wheel which is positioned from the wheel hub. When the wheel is set to rotation, the pendulum freely hangs from the wheel hub under the influence of an off center counterweight having sufficient inertia to prevent rotation of the pendulum with the wheel. The pendulum is used to position one or more magnets to be used to excite field coils, which are mounted with respect to the wheel hub to rotate with the wheel. The magnets and rotating coils cooperate to energize a power utilization circuit also mounted with respect to the wheel hub to rotate therewith. The utilization circuit may include such sensors as desired, typically including though a tire pressure gauge and tire and wheel hub temperature gauges. The apparatus is readily extended to incorporate a fire pressurization pump, which may be a solenoid pump powered indirectly from the rotating coils, or by a magnetic button pump.

Abstract: An air pressure regulating system mounted within a wheel and tire assembly. It primarily includes a temperature sensor and a compressor assembly having a compression chamber and valves. Utilizing centrifugal forces from the rotation of a wheel and tire assembly, air may flow into and out of a tire to automatically maintain the pressure inside a tire relatively constant over a given temperature range. When the pressurized air in the compression chamber is greater than the pressurized air in the tire, the pressurized air in compression chamber flows into the tire. When the pressurized air in the tire is greater than the pressurized air in the compression chamber, the pressurized air in the tire flows into the compression chamber. When the pressurized air in the compression chamber is equal to the pressurized air in the tire, it is in equilibrium, and no air flow occurs. Ambient air flows into and out of the compression chamber through a valve with means to prevent fluids, such as water, from entering the compression chamber.

Abstract: A battery-powered tire pressure monitor and inflation system which is mounted entirely on or within a vehicle wheel, preferably on the inner surface of a wheel cover. The entire system rotates concurrently with the vehicle wheel, thereby eliminating the need for any interconnection between non-rotating and rotating components of the vehicle. The preferred system also incorporates a centrifugal intake valve apparatus, which remains closed until the vehicle wheel exceeds a minimum rotational rate. The centrifugal intake valve closure apparatus thereby prevents fluids or particles from being drawn into the compressor.

Abstract: A device for automatically maintaining desired air pressure within a vehicle tire utilizes deformation of the rotating tire where it contacts the road surface to operate an air compressor. The air compressor is formed in the wheel and connected to the tire, the compressor responsive to deformation of the tire causing compressed air to pass into the tire. The compressor is preferably of a reciprocating piston type having a cylinder adapted to receive a sliding piston, the piston preferably slidably received within a plunger in contact with the inside of the tire. A spring is preferably disposed between the plunger and the piston to limit the motion of the piston to a fixed displacement less than the deformation of the tire, such that the tire inflation system is operable for a wide range of deformations of the tire. Additionally, a centrifugal intake valve is preferably provided that seals off the inlet passageway to the air compressor and opens only when the wheel is rotating rapidly enough so that centrifugal force on potential liquid or particulate contaminants expels such contaminants. Advantageously, the tire inflation device of the present invention is entirely contained within the wheel, without the need for a rotating joint to the vehicle body or frame.

Abstract: A self-inflating tire pump is integrally fixed to a wheel of a vehicle for automatically pumping air into an inflation region of a tire which is mounted on the wheel. The pump includes a piston which is movable radially outward in a cylinder by centrifugal force to draw air from the atmosphere into a compression chamber and is movable radially inward by a biasing element to compress the air in the compression chamber and pump it into the inflation region. The biasing element includes a surface of the piston which is exposed to air pressure in the inflation region, and prevents the piston from moving outward until the wheel rotates above a certain speed, thereby preventing contaminants such as water and dirt from entering the compression chamber during low speed operation of the vehicle in adverse terrain. A stopper mechanism prevents the piston from moving when the tire pressure is above a normal value, thereby reducing frictional wear of the pump.

Abstract: Multiple tires are mounted adjacently parallel to each other on a single wheel. Respective inner spaces of the multiple tires communicate with each other by way of an airflow pipe for the transfer of air. The airflow pipe includes a pneumatic pressure control valve that opens or closes in response to air leaking from one or more of the multiple tires. When one of the multiple tires leaks air rapidly, the pneumatic pressure of the other normal tire decreases, thereby forcing the driver to notice the puncture. If one tire leaks air slowly, its air is replenished from another tire. Thus the respective pneumatic pressures of the individual tires become equal, whereby the driver can continue to drive for a time without risking the serious accident that could occur if he were unaware of the leak.
