Abstract
A multi-speed planetary transmission includes a housing, a drive shaft connectable to a drive train for transferring a drive torque from the drive train to the multi-speed planetary transmission, and four single planetary transmissions arranged along a housing longitudinal axis. The planetary gears feature a sun gear, ring gear, and planetary carrier. Six shift elements are arranged within the housing and are designed as four clutch elements and two brakes. Connecting shafts form connections between the single planetary transmissions, the drive shaft, the output shaft, the clutch elements and/or the brakes. The single planetary transmissions are shiftable such that nine forward gears and one reverse gear are provided, and the shift elements are arranged in a manner easily accessible from outside the housing.
