AUTOMATIC MULTI-STEP GEAR BOX PROVIDED WITH THREE PLANETARY WHEELSETS

摘要

The three planetary clusters (Rs1, RS2, RS3) are co-axial positioned beside each other. The sun gear (SO3) of the third cluster can be attached to the housing (GG) using the first shift element (A). The drive shaft (AN) is directly connected to the sun gear (SO2) of the second cluster, with the second shift element (B) to the sun wheel (SO1) of the first cluster, and with the fifth shift element (E) to a bridge (ST1) at the first cluster. The output shaft (AB) and the ring gear (HO1) of the first cluster and a bridge (ST3) at the third cluster are joined. A bridge (ST2) of the second cluster is connected to the ring wheel (HO3) of the third cluster and the bridge (ST1) of the first cluster is joined to the ring gear (ST2) of the second cluster.
