Hybridized gearbox for motor vehicle i.e. commercial motor vehicle, has rotor coaxially and radially arranged on ring gear, and off-axis coupled to input shaft of region group and ring gear through spur gear

摘要

The gearbox has a main section (1) connected with an outlet side of a region group (2) and an electric machine (3). The region group is provided with a planet stage (7). A ring gear (HO) is rotatably coupled to a rotor (9) of the electric machine. The rotor is coaxially and radially arranged on the ring gear or rotatably mounted on a rotor shaft. An off-axis is coupled to an input shaft (EW) of the region group and the ring gear through a spur gear. The rotor is fixed on the ring gear, and radially surrounds a stator (10) in inner side of gear housing (8). The main section is designed as stage gear boxes and shift gears. The electric machine is designed as permanent energized synchronous machine and quick running asynchronous machine.
