1. A tire inflation system for maintaining a predetermined inflation pressure of a tire that is mounted on a wheel of a vehicle, the wheel rotatable about an axis of rotation, the system comprising:
a base having a mounting structure for engaging a complementary mounting structure of the wheel of the vehicle; a compressor assembly comprising:
a housing fixedly secured to the base and defining an air compression chamber, an air inlet port for taking air into the air compression chamber, and an air outlet port for providing air out of the air compression chamber;a crankshaft having a portion that is aligned along the axis of rotation of the wheel when the base is mounted to the wheel and having a throw that is offset from the axis of rotation, the crankshaft rotatable relative to the base;a reciprocating member coupled to the throw of the crankshaft and defining a portion of an interior surface of the air compression chamber;an air conduit disposed between the air outlet port of the housing and an inflation valve of the tire; anda counterweight fixedly mounted to one end of the crankshaft for supporting relative rotational movement between the crankshaft and the base when the wheel rotates about the axis of rotation. |
