Continuously and/or infinitely variable transmissions and methods therefor
First Claim
1. A continuously variable transmission (CVT) having a longitudinal axis, the CVT comprising:
- a plurality of planets arranged angularly about the longitudinal axis of the CVT, each planet having a through bore that forms a tiltable axis of rotation of the planet;
a main axle arranged along the longitudinal axis of the CVT; and
a lubricant manifold coupled to the main axle, wherein the lubricant manifold is adapted to supply lubricant to the main axle, the lubricant manifold comprising;
a substantially circular body having a central bore;
a flange extending from the circular body, the flange concentric with the central bore, wherein one side of the flange is an engagement face;
an engagement hub extending from the engagement face, wherein the engagement hub has a central piloting recess, and wherein the outer face of the engagement hub has a reaction surface; and
a lubricant passage boss extending from the flange.

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.
