摘要

The transmission (1) has three clutches (K13, K14, K18) provided for coupling a gear box input member (GE) with sun wheels (P1S, P4S), a planet pinion carrier (P3T), and a ring gear (P4H), where each clutch is attached to the sun wheels and/or the carrier, and/or the ring gear. The clutches are arranged before a planetary gear set (PGS1) when viewing from the gear box input member in a direction of a gear box output member (GA). The planetary gear set includes one of the sun wheels that combs with a planetary gear (P1P) arranged on another planet pinion carrier (P1T).
