- the invention relates to a device for active self-holding an electromotive actuator, preferably for a clutch actuation system, which remains motionless upon application of a holding voltage.
- hydrostatically actuated dual clutch systems which have two hydrostatic stretches.
- the hydrostatic sections serve for the direct actuation of partial clutches of the double clutch and each connect a Kupplungs technicallyzylin- with a clutch master cylinder.
- a piston is arranged, which is adjusted by an electric motor.
- the adjustment movement of the piston of the clutch master cylinder is transmitted via a hydraulic medium, such as hydraulic oil, through the hydraulic routes to an associated piston of the clutch slave cylinder.
- the piston of the clutch slave cylinder acts directly on a clutch plate of the respective part clutch.
- the partial clutches are advantageously closed by the electromotive adjustment of the piston in the master cylinder only as far as necessary to transmit a requested torque can.
- the electromotive adjustment of the master cylinder piston is realized by electromotive actuators, which are designed self-holding. Due to the self-holding the split couplings do not open automatically in case of failure of the electrical components.

- the energy store is arranged between a, the electromotive actuator-driving control unit and the electromotive actuator.
- the energy store is arranged within the electromotive actuator. The choice of the positioning of the energy storage can be done due to the available space. After an error detection in both cases, the motor phases of the electromagnetic actuator are applied for a certain time with the holding voltage, whereby a movement of the clutch is prevented or delayed.
- the energy store is designed as a capacitor, which is connected on the input side to a supply voltage and outputs the holding voltage for the electromotive actuator on the output side.
- the holding voltage is switched directly to at least one of the motor phases of the electromotive actuator, so that further energy for the electromotive actuator is provided to freeze a movement of the clutch.
- the capacitor is connected to the power supply via a line which can be used simultaneously for fault detection and can be charged by the latter.
- the line connecting the capacitor to the power supply is designed as a low-active error signal line, on which a plausibility check can be performed, it being determined whether a failure of the supply voltage or a cable break exists. This is easily recognized by the fact that no voltage is applied to this line.
- the capacitor in an output circuit, which connects this with the electromotive actuator, a switch which is closed when an error detection.
- this switch which is activated when a 0 volt signal is applied to the dedicated line and thus no charging of the energy storage, the capacitor is connected to the electromotive actuator and the holding voltage is applied to the electromotive actuator.
- an input circuit of the capacitor has a first resistor for limiting the charging current of the capacitor and an output circuit has a second resistor for limiting the holding voltage.
- a diode is connected upstream of the first resistor in the input circuit.
