Continuous power dividing hydromechanical transmission for motor vehicles

摘要

The continuously-variable transmission system, comprising input (14) and output (15) shafts, two plain epicycloid gear train (11, 12) and a hydrostatic variator, has an axially-projecting toothed ring (130) joined by a weld (131) to the front face of th crown wheel (C1) of the first epicycloid gear train connected to the input shaft and designed to mesh with the input gear (117) the hydrostatic variator. The front face of an output gear (126) on the output shaft has a second toothed ring (134) joined to i face by a weld (135) and meshing with one of the output gears (BV) of the variator. In addition, the satellite carriers (PS1, PS of the two gear trains are also welded together.
