  • Publication number: 20220290476
    Abstract: An actuating mechanism for actuating a charging or fueling flap on a charging or fueling compartment received on or in a body component of a vehicle, wherein the charging or fueling flap is reversibly movable between a closed position and an open position, wherein a flap lock is provided for locking the charging or fueling flap in its closed position. The actuating mechanism includes a drive having a drive shaft, which is operatively connectable to the charging or fueling flap such that, upon rotation of the drive shaft, the charging or fueling flap is movable relative to the charging or fueling compartment. The actuating mechanism further includes a mechanical control or switching mechanism, which is configured such that, upon rotation of the drive shaft to manipulate the flap lock, a rotational movement of the drive shaft can be tapped with the aid of the mechanical control or switching mechanism.

  • Patent number: 10682996
    Abstract: The electromechanical brake force booster for a vehicle brake system comprises a drive arrangement for driving at least one actuating device which is designed for actuating a brake cylinder. The drive arrangement has at least one electric motor and a gearing for coupling the electric motor to the at least one actuating device. The gearing comprises at least one second spur gear and at least one first spur gear. Furthermore, the gearing has an intermediate gearing stage. The intermediate gearing stage couples the electric motor to the second spur gear and to the first spur gear in torque-transmitting fashion. The intermediate gearing stage drives the second spur gear directly and the first spur gear via at least one intermediate gear.
