Abstract
A drive unit is provided for a motor vehicle, including an internal combustion engine with an output shaft, a starting element that can be driven by the output shaft, a transmission that can be driven by the output shaft via the starting element, and a bellows mechanism via which the starting element can be driven by the output shaft. The bellows is configured as a folding bellows with a plurality of walls overlapping each other in the axial direction, such that the bellows can be pulled apart and compressed again without the bellows being damaged or deformed plastically as a result. The bellows is utilized as a balancing clutch, via which the starting element is coupled to the output shaft, such that torques are transmitted via the bellows between the starting element and the output shaft.
Claims15
