Abstract
An adjustment drive that includes an electric motor, a transmission having a self-locking transmission stage, an output, and a safety clutch having a free travel. The safety clutch is operable to separate, in an event of an excessive external torque introduced via the output, the self-locking transmission stage from the external torque. The adjustment drive also includes at least one compressible damping element arranged in the free travel to enable haptics of an external movement demand introduced via the output.
Claims15
An adjustment drive, comprising:
- an electric motor;
- a transmission having a self-locking transmission stage, an output, and a safety clutch having a free travel and is operable to separate the self-locking transmission stage from the external torque, in an event of an excessive external torque introduced via the output, the safety clutch including a motor-side gearwheel, an output-side gearwheel, and a connection element operable to connect the motor-side gearwheel to the output-side gearwheel, the connection element having a positive-locking connection to one of the motor-side gearwheel or the output-side gearwheel in a closed state of the safety clutch;
- and
- at least one compressible damping element arranged in the free travel to enable haptics of an external movement demand introduced via the output, wherein the connection element has the free travel and the damping element for the other of the output-side gearwheel or the motor-side gearwheel.
