Abstract
An infinitely variable transmission (IVT) having a rotatable input shaft arranged along a longitudinal axis of the transmission. In one embodiment, the input shaft is adapted to supply a lubricant to the interior of the transmission. In some embodiments, a stator assembly is coupled to, and coaxial with, the input shaft. The IVT has a plurality of planets operably coupled to the stator assembly. The planets are arranged angularly about the longitudinal axis of the transmission. In one embodiment, a traction ring is operably coupled to the planets. The IVT is provided with a housing that is operably coupled to the traction ring. The housing is substantially fixed from rotating with the input shaft. The traction ring is substantially fixed from rotating with the input shaft. In some embodiments, the IVT is provided with a lubricant manifold that is configured to supply a lubricant to the input shaft.
