Power branched continuously variable automatic transmission has two driving modes as power branched modes in which one part of drive power is directed through continuously variable gear and second part mechanically directed to PTO

摘要

The power branched continuously variable automatic transmission (1) has three driving modes, whereby two driving modes are designed as power branched modes in which a part of the drive power is directed through a continuously variable gear (2) and a second part of the driving power is mechanically directed with positive engagement to the power take-off shaft (5). The first and the third driving modes are designed as power branched modes. The automatic transmission has a summing differential (3) in which the power fluxes of the power branched modes are summed.
