Stepless power split transmission and method for operating a stepless power split transmission

摘要

The invention relates to a continuously variable power transmission and a method for operating a continuously variable power transmission (1) for a vehicle, the transmission (1) being provided to drive a drive machine (2) on the input side, at least indirectly via a drive shaft (3) to connect the output shaft provided for the output, and wherein the transmission (1) a plurality of shifting elements (K1, K2, K3, K4, B) and a variator (5) for the stepless adjustment of a gear ratio and for the realization of several driving ranges (F1, F2 , F3, F4), characterized in that the drive machine (2) via the switching elements (K1, K2, K3, K4, B) with the variator (5) and the output shaft (4) is linearly coupled to at least a first Initiate gear ratio (G1) with a fixed ratio.
