摘要： A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed

摘要： Inventive embodiments are directed to components, subassemblies, systems, and/or methods for infinitely variable transmissions (IVT) having a variator provided with a plurality of tilting spherical planets (522). In one embodiment, a variator is provided with multiple planet arrays (222A, 222B). In another embodiment, a hydraulic system is configured to control the transmission ratio of the IVT. Various inventive idler assemblies (562) and planet- pivot arm assemblies (579) can be used to facilitate adjusting the transmission speed ratio of an IVT. Embodiments of a transmission housing and bell housing (531) are adapted to house components of an IVT and, in some embodiments, to cooperate with other components of the IVT to support operation and/or functionality of the IVT. Various related devices include embodiments of, for example, a control feedback mechanism (292), axial force generation and management mechanisms (235), a control valve (1605) integral with an input shaft, and a rotatable carrier (515) configured to support planet-pivot arm assemblies (579).

摘要： Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one embodiment, a main axle (112) is adapted to receive a carrier assembly (101, 400, 600, 800) to facilitate the support of components in a CVT (100). In another embodiment, a carrier includes a stator support member (206, 304, 402, 502, 602, 802) and a stator interfacial member (208, 504). In some embodiments, the stator interfacial member is configured to interact with planet subassemblies of a CVT. Various inventive planet subassemblies (108, 406, 806) and idler assemblies (109, 700) can be used to facilitate shifting the ratio of a CVT. In some embodiments, the planet subassemblies include legs (244, 2444, 424, 810) configured to have a sliding interface with a carrier assembly. Embodiments of a hub shell (102), a hub cover (104) 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.
