Automotive transmission mechanism

摘要

The pilot gearbox has a single epicyclic differential (23) outside the central shaft, and whose first shaft (26,27) is coupled by a gear train (28,29) to the non-adjustable machine (H1). Its second shaft (31) to the central shaft and its third (32,39), extending into the main gearbox, via a second gear train (40,41) to the second layshaft (8). A third gear train (34,35) couples the central shaft to the second hydraulic machine (H2), which is adjustable in both directions from the O position. The central shaft also extends into the main gearbox, driving the first layshaft (7) via a fourth gear train (37,38).
