Abstract: A tire safety system mounts on a vehicle wheel rim inside a pneumatic tire. A tire air pressure sensor produces a tire air pressure reading mounted inside the tire. An inflatable member forms a toroidal expandable internal safety structure. The inflatable member is mounted against the vehicle wheel rim. The chemicals container inside the inflatable member receives an electrical signal at an activation input. The chemicals container creates pressurized gas inside the inflatable member for inflation when a signal is received at the activation input. A circumferential radially expandable protective belt mounted around the inflatable member expands with inflatable member inflation to accommodate operation the tire when expanded. A computer receiving tire air pressure readings from the tire air pressure sensor sends a signal to the activation input upon a sudden change in tire air pressure.

Abstract: A pneumatic tire monitoring system for monitoring pneumatic tire conditions for one or more tire/wheel assemblies mounted on a vehicle, preferably in combination with a tire pressurizing and regulating apparatus, comprises a transponder with a transmitting antenna mounted on the wheel for transmitting a signal indicating tire condition, one or more receivers with receiving antennas fixedly mounted on the vehicle, and circuitry for processing the received signals; the system characterized in that: circuitry for each transponder is on a printed circuit board within a protective housing coaxial to the hub of the wheel or wheel carrier; and each transmitting antenna is selected from the group comprising a partial loop antenna, a helical antenna, a circular dipole antenna, and a small coupling coil adjacent to an endless hoop antenna. The partial loop antenna is mounted in each housing affixed around a portion of the circumference of the printed circuit board, having an angular arc length, and comprises a serpentine portion for increasing the effective length of the partial loop antenna without also extending the angular arc length. The angular arc length and the affixed placement are determined for avoiding RF signal interference due to interaction with signal-interfering objects in the housing. Additionally, the partial loop antenna has an end portion that can be trimmed for adjusting the effective length to enable tuning of the antenna for optimum transmission at different radio transmission frequencies.

Abstract: A pneumatic control apparatus and method controls gas pressure inside a tire (40) mounted on a wheel (32) which rotates about the centerline of an axle (30). A bleeder valve (28) is mounted on a body coaxially aligned with the axle centerline and is in fluid connection with a pneumatic fitting (23) on the tire. The bleeder valve allows gas inside the tire to be relieved to the atmosphere when the gas is above a set pressure. The coaxial alignment of the bleeder valve with the axle centerline permits the bleeder valve to relieve gas pressure unaffected by centrifugal forces.

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 tire pressure management system including a tire condition monitor connected to the tire so as to be interactive with air pressure in the tire and for selectively measuring a pressure in the tire, a controller, and a display. The tire condition monitor includes a transmitter and a receiver. The controller also has a transmitter and a receiver connected thereto. The transmitter of the controller serves to transmit a first radio signal to the receiver of the tire condition monitor. The receiver of the controller serves to receive a second radio signal from the transmitter of the tire condition monitor. The display is connected to the controller so as to display a humanly perceivable indication of a condition of the tire. An air compressor is mounted to a wheel of the tire so as to deliver air to an interior of the tire when the pressure of the tire is below a predetermined value. A power generator is connected to the wheel of the tire and includes an alternator magnet assembly and an induction coil assembly which are connected to the wheel of the tire such that relative rotation occurs therebetween as the tire rotates.

Abstract: A self-regulating tire pressure system and method employs a bistable valve (10) that allows air from a high pressure reservoir (6) to replenish the pressure within a tire (4) when it has fallen below an actuating pressure, and discontinues its operation only after the tire pressure has increased to a closing pressure that is greater than the actuating pressure. The system is capable of sensing the valve's (10) frequency of operation as an indication of a slow tire leak when the frequency exceeds a predetermined threshold, of sensing the number of valve (10) operations and the duration of each operation as an indication of a flat tire condition when the number of operations for a predetermined duration exceeds a second threshold, and of sensing the duration of the valve's (10) operation as an indication of a low reservoir (6) pressure condition when that duration exceeds a third threshold. The valve (10) includes a bistable diaphragm (94, 120) that receives a reference pressure on one side and the tire pressure on its opposite side, and snaps between two stable positions respectively opening and closing the valve (10) in response to the tire pressure falling below the actuating pressure and then increasing to the closing pressure.

Abstract: An automatic tire inflation-pressure regulating system for wheeled vehicles with pneumatic tires. The system has a system control assembly in the vehicle operator's compartment, control signal transmitter assemblies on the vehicle body in close proximity with each vehicle road wheel, and a tire pressure-regulating wheel assembly on each wheel. The transmitter assemblies convert electrical command signals initiated by the control assembly to RF signals that are received by an electronic module in each wheel assembly. Means in each wheel assembly selectively deflate or inflate their respective tires in response to the RF control signals. Gas under pressure for inflating the tires is provided either by a plurality of gas generators or by a pressurized gas-generating liquid.

Abstract: A tire equalizer comprises a housing having upper and lower chambers divided by a flexible diaphragm opposing a seat in the upper chamber connected to one of the tires. The diaphragm is urged toward the seat by a spring-pressed inverted cup larger in diameter than the diaphragm and having an arm extended longitudinally from the cup away from the spring. The arm is curved in horizontal cross-section and its upper end is formed with a slot receiving an off-center pin on the back of an indicator disc. Also connected to the upper chamber is a fill conduit, and a conduit to the other tire.
