A centrifugal pendulum for damping rotational non-uniformities introduced via a drive shaft of a motor vehicle engine is provided, having a carrier flange which is connectable to the drive shaft, and having a pendulum mass, which can oscillate in pendular fashion relative to the carrier flange on a pendulum path, for generating a restoring moment directed oppositely to the rotational non-uniformity, wherein the pendulum path has a central, first path part (16) for providing an adjustment order which is constant and/or decreases in the case of an increasing swing angle of the pendulum mass relative to the carrier flange, and in each case one second path part (18), which adjoins a respective end of the first path part (16), for providing an adjustment order which increases with increasing swing angle of the pendulum mass relative to the carrier flange. Owing to the differently configured adjustment orders of the first path part (16) and of the second path part (18), it is possible, in different resonance ranges such as may arise in particular between an odd-numbered gear and an even-numbered gear of a dual-clutch gearbox being engaged, for rotational vibrations to be dampened in inexpensive fashion, such that it is made possible to realize a drivetrain for a motor vehicle with inexpensively damped rotational non-uniformities.
