A drive unit (1) for an electric vehicle, the drive unit comprising:
- an electric machine (4) for driving the electric vehicle, and the electric machine being arranged in a housing and having a driveshaft (13) for transmitting torque from the electric machine (4) to an axle of the electric vehicle, and
- at least one mounting system (2, 3) for mounting the drive unit on a body of the electric vehicle, and the housing (1a) of the drive unit (1) being designed as the mounting system for mounting the drive unit (1) on the body of the electric vehicle.
A method of fixing a drive unit (1) in an electric vehicle, the drive unit has an electric machine (4) for driving the electric vehicle, the electric machine is arranged in a housing and has a driveshaft (13) for transmitting torque from the electric machine (4) to an axle of the electric vehicle, and at least one mounting system (2, 3) for mounting the drive unit on a body of the electric vehicle, the housing (1a) of the drive unit (1) is designed as the mounting system for mounting the drive unit (1) on the body of the electric vehicle, the method comprising the steps of:
- inserting at least one spring link (6) into a recess (10) of the housing (1a) of the drive unit (1), and
- fixing the at least one spring link (6) in the recess (10) by at least one of bracing the spring link in the recess (10) and by screwing on a plate.
The drive system for an electric vehicle in combination with a drive unit that comprises an electric machine (4) for driving the electric vehicle, the electric machine is arranged in a housing and has a driveshaft (13) for transmitting torque from the electric machine (4) to an axle of the electric vehicle, and at least one mounting system (2, 3) for mounting the drive unit on a body of the electric vehicle, the housing (1a) of the drive unit (1) is designed as the mounting system for mounting the drive unit (1) on the body of the electric vehicle, the body of the electric vehicle having at least one torsionally rigid cross-member (2) on which the housing (1a) of the drive unit (1) is fixed, the drive unit comprises a torque support (5) that is fixed on a stabilizer (8) essentially at a center of the stabilizer, and a spring link (6) is fixed on the housing (1a) of the drive unit (1).
