Continuously variable power split transmission with at least four driving ranges

摘要

A continuously variable power split transmission (3) with at least four driving ranges is described, within which the ratio of the power split transmission (3) in the region of a variator (5) can be infinitely varied. A plurality of shafts (W11 to W14) comprehensive first planetary gear set (P1) via a plurality of switching elements (K1 to K4) with a plurality of shafts (W21 to W23) having another planetary gear set (P2) operatively connected to a transmission output shaft (6) in Active compound is or can be brought into operative connection. According to the invention, the first planetary gearset (P1) comprises four shafts (W11 to W 14) and is operatively connected to or connected to a transmission input shaft (7) and a first shaft (8) of the variator (5) via a first shaft (W11) Active compound can be brought. Furthermore, the first planetary gear set (P1) via a second shaft (W12) with a second shaft (9) of the variator (5) in operative connection, while the first planetary gear set (P1) via a third shaft (W13) with switching element halves (10, 11) of two switching elements (K1, K3) and via a fourth shaft (W14) with a switching element half (12) of a further switching element (K2) is coupled.
