Title: SHIFTABLE TWO-SPEED TRANSMISSION, IN PARTICULAR FOR EDRIVE APPLICATIONS
Abstract:
Shiftable two-speed transmission (2) for transmitting propulsion power within a motor vehicle drivetrain, comprising a rotationally driven input member via which, when propulsion power is being transmitted, the propulsion power is introduced into the transmission (2), and an output member via which the propulsion power can be transmitted out of the transmission (2), wherein subject to the shift position of a shiftable clutch (10), a direct drive (i=1) or a transmission stage having a transmission ratio (i#1) which differs from the direct drive can be achieved between the input member and the output member, and three assembly units, i.e. an external gear unit (4), a planetary gear unit (6) and a sun gear unit (8), are provided, characterized in that, when propulsion power is being transmitted, the propulsion power is introduced into the transmission (2) via the external gear unit (4).
