Abstract

A power split transmission (LG) of vehicle a traction drive (F) includes a continuously variable transmission (G) and a summing transmission (SG). The continuously variable transmission (G) has a primary unit (P) and a secondary unit (S) driven by the primary unit (P). The primary unit (P) has a driveshaft (TW1) connected, directly and without the interposition of a clutch device, with the sun gear (SR) of the summing transmission (SG). The secondary unit (S) has a driveshaft (TW2) connected, without the interposition of a clutch device, with a ring gear (HR) or a planetary carrier (PT) of the summing transmission (SG). The planetary carrier (PT) or the ring gear (HR) of the summing transmission (SG) form an output element of the summing transmission (SG), which is in a driving connection with the wheel drive.
