Abstract
A drive unit (1) including an electric motor (2) and a first planetary drive (7) with a first shifting clutch (3) for selecting a first connection between the electric motor (2) and a driven element (6) of the drive unit, and with a second shifting clutch (4) for selecting a second connection between the electric motor (2) and the driven element (6). A transmission connection is formed between the electric motor (2) and the first shifting clutch (3) by the first planetary drive (7).
Claims9
A drive unit comprising an electric motor, a first planetary drive, a first shifting clutch for selecting a first connection between the electric motor and a driven element of the drive unit, a second shifting clutch for selecting a second connection between the electric motor and the driven element, wherein a transmission connection is formed between the electric motor and the first shifting clutch by the first planetary drive, the first and second shifting clutches are engageable and disengagable by a common actuator element of an actuator arrangement acting selectively on both of the shifting clutches.
A drive unit comprising an electric motor, a first planetary drive, a first shifting clutch for selecting a first connection between the electric motor and a driven element of the drive unit, the driven element is connected to a gearwheel in a torque transmitting manner, a second shifting clutch for selecting a second connection between the electric motor and the driven element, wherein a transmission connection is formed between the electric motor and the first shifting clutch by the first planetary drive, the first and second shifting clutches are engageable and disengagable by a common actuator element of an actuator arrangement acting selectively on both of the shifting clutches, and wherein a transmission connection is formed between the first and second shifting clutches and a differential by the gearwheel, wherein the transmission connection between the first and second shifting clutches and the differential is formed by a second planetary drive, the gearwheel is a second sun gear of the second planetary drive that is in meshed engagement with second planet gears that are supported for rotation and the second planet gears are held on a second planet carrier and the second planet gears are in meshed engagement with a second ring gear that is fixed on a housing of the drive unit.
