Devices and systems for controlling tire pressure

A system for retrofitting a vehicle to have continuously controlled tire pressure, the system comprising:

• a controller configured to facilitate the control of tire pressure at a first tire associated with the vehicle;
• and
• a first device for continuously controlling tire pressure, the first device being controlled through the controller and comprising:
• a fixed non-rotating member fixedly attached to the vehicle, the fixed non-rotating member having at least one first seal surface, the at least one first seal surface configured to be in fluid communication with a compressed air source;
• and
• a non-fixed rotating member rotatably attached to the fixed non-rotating member, the non-fixed rotating member being configured to rotate with the tire and having at least one second seal surface, wherein an air chamber defined within a volume between interacting the at least one first seal surface and the at least one second seal surface causes fluid communication between an interior space of the tire and the compressed air source, wherein the non-fixed rotating member comprises a plurality of apertures configured to facilitate mounting of the tire, a number of the plurality of apertures being at least twice as many as a number of tire lug bolts for a single tire, wherein a first half of the plurality of apertures is configured to receive the tire lug bolts, and wherein a second half of the plurality of apertures is configured to attach the tire to the non-fixed rotating member.

A device for continuously controlling tire pressure, the device comprising:

• a hub assembly comprising:
• a first outer plate having:
• a first edge defining a first circumference of a first portion of the first plate,
• a second recessed edge defining a second circumference of a second portion of the first plate, and
• an air channel having a first opening disposed on a surface of the first edge and a second opening disposed on a surface of the second edge, the air channel extending between the first and second openings;
• a second inner plate having a first edge defining a first circumference of the second plate, the second plate being configured to couple to the first plate, the coupled plates being configured to attach to and rotate with a wheel of a vehicle;
• and
• a central ring plate having a first outer edge defining a first circumference, a second inner edge defining a second circumference, and an air channel having a first opening disposed on a surface of the first edge and a second opening disposed on a surface of the second edge, the air channel extending between the first and second openings, the ring plate being configured to threadedly connect to a portion of the vehicle, such that the ring plate does not rotate with the wheel of the vehicle;
• wherein the coupled plates are configured to be in communication with the ring plate;
• and
• a compressed or pressurized air source capable of producing pressurized air effective to maintain tire pressure at a predetermined level.
