Infinitely variable transmissions, continuously variable transmissions, methods, assemblies, subassemblies, and components therefor

摘要

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).
