Multi-step reduction gear for use in planetary construction, particularly for automatic gear for a motor vehicle, has planetary gear set, which is formed as plus-planetary gear set with sun wheel

摘要

The multi-step reduction gear has a planetary gear set (RS1), which is formed as plus-planetary gear set with a sun wheel (SO1). Another planetary gear set (RS2) is formed as plus planetary gear set with a bar (ST2). Third planetary gear set (RS3) is formed as minus-planetary gear set with another bar (ST3). Fourth planetary gear set (RS4) is formed as minus-planetary gear set with third bar (ST4).
