Multi-speed planetary wheel set transmission, has six torque transmission mechanisms selectively engageable in combinations of two for producing eight forward gears and reverse gear between input element and output element

摘要

The transmission (10) has connecting elements continuously connecting elements of a planetary wheel set (16) with other elements of another planetary wheel set (20). Six torque transmission mechanisms are selectively engageable for connecting one of the elements with other elements and a transmission housing (50). The six torque transmission mechanisms are selectively engageable in combinations of two for producing eight forward gears and a reverse gear between an input element (12) and an output element (22).
