976,191. Variable-ratio gearing. REGIE NATIONALE DES USINES RENAULT. Dec. 12, 1960 [Dec. 16, 1959], No. 16938/64. Divided out of 975,941. Heading F2D. Epicyclic gearing for a frontaxle - drive, front - engined vehicle, or for a rear-axle-drive, rear-engined vehicle has the epicyclic gearing disposed on the opposite side of the final reduction and differential gearing to the engine which drives the pump 212 of a hydrodynamic torque converter the turbine 213 of which drives an input shaft 216 of the epicyclic gear. The epicyclic gearing comprises three overlapping trains, a first train having an input sun 217 and planet pinions 218 meshing planets 219 of the second train, the planets 219 meshing an output ring 224 and a sun 235 which can be connected to the sun 236 of the third train by a clutch 251 for direct drive and can be stationed by a brake 254 for second gear. The sun 236 meshes planets 220 integral with the planets 218 and the planet carrier is stationed by a brake 223 for first gear. Reverse is obtained by applying a brake 240 to station the sun 236. |
