20130288848 | CONTINUOUSLY VARIABLE TRANSMISSIONS AND METHODS THEREFOR - Components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT) having a variator provided with a plurality of tilting, traction planets and traction rings are described. In one embodiment, a variator is coupled to a rangebox to provide multiple operating modes. In another embodiment, a hydraulic system is configured to control the transmission ratio of the variator and the rangebox. Shift-cam-and-sun subassemblies can be used to facilitate shifting of the transmission ratio of a CVT. A transmission housing and bell housing can be 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. Related devices include, for example, a pivot arm, a control feedback mechanism, axial force generation and management mechanisms, a control valve integral with an input shaft, a pivot pin hub, and a rotatable carrier configured to support planet-pivot arm assemblies. | 10-31-2013 |
20140038770 | GENERATING DEVICE FOR AIRCRAFT - An electric power generating device ( | 02-06-2014 |
20140045647 | DRIVE FORCE DISTRIBUTING APPARATUS - A drive force distributing device includes first and second rollers rotatable jointly with a main drive wheel system and a subordinate drive wheel system, respectively. A shaft portion of the second roller is rotatably supported via a bearing in an eccentric bore of a crankshaft that in turn is rotatable about a fixed axis of a housing. Control of the drive force distribution between the main drive wheels and the subordinate drive wheels is carried out by turning the second roller by the rotation of the crankshaft about the fixed axis to adjust the inter-roller pressing force by an adjustment mechanism which performs a reverse rotation control in which the turning direction of the second roller and the rotation direction of the second roller are in the opposite direction when the detected oil temperature exceeds a predetermined temperature. An identical rotation control is performed otherwise. | 02-13-2014 |
20140141932 | ROLLING BODY, METHOD FOR PRODUCING ROLLING BODY, AND DYNAMIC FORCE TRANSMISSION DEVICE - A high durability roller, a manufacturing method thereof and a power transmission device with the high durability roller are provided. The roller for a power transmission device that comprises a plurality of rollers in contact with each other directly or with lubricant between them, includes: a metal base having a Young's modulus of 220 GPa or less; and a coating that is formed on a surface of the metal base, includes hard particles and a metal component composed of at least either simple metal or alloy, and has a Young's modulus of 250 GPa or more. The power transmission device includes the roller. The method of manufacturing the roller includes: forming the coating on the surface of the metal base by thermal spraying using a thermal spray material that comprises the hard particles and the metal component composed of at least either simple metal or alloy. | 05-22-2014 |
20150369348 | CONTINUOUSLY VARIABLE TRANSMISSION - 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 idler-and-shift-cam 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. | 12-24-2015 |
