A method for operating an electromagnetic actuator () with an actuating pin () is proposed which comprises the following steps: &#x2014;determining a pin actuation actual dead time (t), during which the magnetic armature () is substantially immobile while a magnetic coil () is supplied with current, wherein the actual dead time ends with the current break-in at the magnetic coil, as a result of counter induction of the magnetic armature overcoming the magnetic force threshold; &#x2014;determining, before a subsequent pin actuation, the starting time of the magnetic coil current supply, wherein the starting point of the current is advanced compared with that of the target movement start of the pin out of the actuator housing () and the determined actual dead time.

Method for controlling an actuator

A bearing mechanism () for a transverse leaf spring () for mounting in the region of a vehicle axle of a vehicle. The bearing mechanism () has two outer bearing shells () that can be connected together and insertion devices () with at least some regions of which are encompassed by the outer bearing shells () and which each comprise at least two layer elements (A,B,C andA,B,C) with different stiffnesses. In the assembled state, the insertion devices () are each disposed between the outer bearing shells () and the transverse leaf spring (). The insertion devices () can be connected to the outer bearing shells () and the transverse leaf spring (), via a bolt device () which connects the outer bearing shells () together and to a vehicle chassis at least in a force locking manner.
