Actuator arrangement for electromechanically operatable decoupler of drive chain for motor vehicle, has safety mechanism connected to control device with motor to supply power to motor independent of device during error condition of motor

摘要

The arrangement (24) has an electric motor (26) coupled with an electromechanically operatable decoupler (14) to operate the decoupler, and a control device (34) for controlling the electric motor and connected with an electrical power supply mechanism (36). A safety mechanism (50) is connected parallel to the control device with the electric motor to supply electrical power to the electric motor independent of the control device during an error condition of the electric motor. The safety mechanism has a safety-hardware, which is provided separately from the control device.
