The invention relates to an active spring unit for the sprung mounting of a wheel suspension element relative to a vehicle body. To provide an optimized active wheel suspension that is designed both for fast and for slow adjustments, provision is made according to the invention whereby the active spring unit has a spring element which is mounted on the vehicle body and which has a torsion portion which extends along a torsion axis from a wheel region, in which said torsion portion is couplable torque-transmittingly to the wheel suspension element, to a primary drive region, in which said torsion portion is coupled torque-transmittingly to a self-locking primary actuator unit, wherein a non-self-locking secondary actuator unit is torque-transmittingly coupled at least indirectly to the wheel region, at least partially bypassing the torsion portion.
