Gear assembly for use in electric drive transmissions

A gear assembly for use with an electric motor, the gear assembly comprising:

• a drive gear adapted to be connected to an output shaft of an electric motor, the drive gear being rotatable around a transmission axis;
• a planetary gear assembly comprising a sun gear, two or more planetary gear members rotatably supported on a carrier about respective planetary gear axes and meshing with one or more of the sun gear and a ring gear, an input stage connected to the drive gear, and an output stage adapted to be connected to a drive member for rotation of the drive gear about the transmission axis;
• a clutch member adapted for slippingly connecting the ring gear with the carrier or with the drive member;
• and
• a brake member adapted for fixedly engaging a part of the planetary gear assembly with a locking part of the gear assembly;
• wherein, in a low speed range of the gear assembly, the clutch member and the brake member are operated such that torque is transmitted from the drive gear to the planetary gear assembly, and through the output stage of the planetary gear assembly to the drive member;
• and
• wherein, in a high speed range of the gear assembly, the clutch member and the brake member are operated such that the carrier is fixedly connected to the drive member and is rotated about the transmission axis such that torque is transmitted from the drive gear to the drive member via the carrier.
