CONTINUOUSLY VARIABLE TRANSMISSION
First Claim
1. A carrier for a continuously variable transmission (CVT), the carrier comprising:
- a generally cylindrical hollow body having a first end and a second end;
a first support axle coupled to the first end, the first support axle extending axially from a first end exterior surface;
a second support axle coupled to the second end, the second support axle extending axially from a second end exterior surface;
a plurality of openings arranged radially about the outer periphery of the cylindrical hollow body;
a first plurality of radial grooves formed on a first end interior surface; and
a second plurality of radial grooves formed on a second end interior surface, wherein the first and second pluralities of radial grooves are each configured to couple to a respective plurality of skew-shift reaction rollers of the CVT.

Abstract
Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one embodiment, a main axle is adapted to receive a shift rod that cooperates with a shift rod nut to actuate a ratio change in a CVT. In another embodiment, an axial force generating mechanism can include a torsion spring, a traction ring adapted to receive the torsion spring, and a roller cage retainer configured to cooperate with the traction ring to house the torsion spring. Various inventive power roller-leg assemblies can be used to facilitate shifting the ratio of a CVT. Embodiments of a hub shell and a hub cover are adapted to house components of a CVT and, in some embodiments, to cooperate with other components of the CVT to support operation and/or functionality of the CVT. Among other things, shift control interfaces and braking features for a CVT are disclosed.
