Adjusting drive for cam shaft adjusters has reinforcement means assigned to rotor to increase magnetic force acting axially on latter

摘要

The adjusting drive has a reinforcement means (28) assigned to the rotor (27) of the servo shaft (13) to increase the magnetic force which acts axially on the rotor. The rotor engages with a rotor belt in an air gap (22) of the stator (21). Independent claim describes rotor for adjusting drive where a reinforcement is provided on the support (26) connectable to the servo shaft for increasing the magnetic force. Independent claim describes cam shaft adjuster with adjusting drive with reinforced magnetic action.
