Abstract
The air transmission structure includes a stator—having an annular outer wall with at least one aperture, an air inlet, and an air passage between the air inlet and the at least one aperture on the annular outer wall—biased against the non-rotating spindle. A housing includes interior annular walls mounted in radially spaced relation with the annular outer wall of the stator to form an annular cavity therebetween, and at least one aperture formed through the interior annular wall, and air outlet, and an air passage between the at least one aperture and air outlet. A seal is inserted within the annular cavity and defines a radial air passage between the apertures defined within the stator annular outer wall and the housing interior annular wall. An annular bearing between the stator and housing is configured to allow the housing to rotate with respect to the stator.
