| 20220299091 | TENSIONING DEVICE WITH A SINGLE SECURING RING - A tensioning device, more particularly a hydraulically actuated chain tensioner, for a chain drive of an internal combustion engine, having a tensioner housing, a tensioning piston which is displaceably guided in a piston bore of the tensioner housing and has a piston skirt, a transport securing means for fastening the tensioning piston in the tensioner housing, a adjustment apparatus for incrementally adjusting and limiting the working range of the tensioning piston, and a final position securing means for the captive arrangement of the tensioning piston in the piston bore. The transport securing means, the adjustment apparatus and the final position securing means together have a single securing ring for fastening the tensioning piston in the tensioner housing, the incremental adjustment and limiting of the working range of the tensioning piston and the captive arrangement of the tensioning piston. A chain drive, more particularly a control chain drive, of an internal combustion engine, having such a tensioning device is also provided. | 2022-09-22 |
| 20220299092 | Infinitely Variable Multi-Epicyclic Friction Transmission System for Electric Motor - Infinitely variable multi-epicyclic friction transmission system including a main shaft, ball race discs, a splined tube, and twin planetary cone assemblies attached to a planetary carrier and disposed circumferentially around the splined tube. Each twin planetary cone assembly comprises a torque tube and a planetary cone-hemisphere structure comprising a planetary cone integral with hemisphere at its apex, wherein the planetary cone-hemisphere structure rolls inside the torque tube via the hemisphere, and wherein a slant height of the twin planetary cone assemblies is parallel to the main shaft. System also includes a series of spherical planets, a reaction ring disposed around the twin planetary cone assemblies configured to slide along the planetary cone assemblies to vary a gear ratio, and ball gear retaining rings. Each of the ball gear retaining rings is mounted on one of a plurality of ball gears which are mounted on the ball race discs. | 2022-09-22 |
