US 10,865,854 B2 · Transmission

Abstract

This application discloses a transmission having a plurality of transmission sections, wherein each transmission section comprises: a driven primary shaft (1); at least one secondary shaft (13), which is arranged to rotate independently, in particular axis-parallel, with respect to the primary shaft (1); and a clutch arrangement (4, 5), which is formed to selectively couple the primary shaft (1) directly with a driven shaft or to couple the secondary shaft (13) or one of the secondary shafts between the primary shaft (1) and the driven shaft, wherein the driven shaft is a primary shaft (1) of a further transmission section or an output shaft of the transmission, wherein the coupled secondary shaft (13) comprises a predetermined transmission ratio with respect to the primary shaft (1), wherein when multiple secondary shafts are provided, respective coupled secondary shafts comprise different transmission ratios with respect to the primary shaft (1).
