Abstract
A safety clutch for an electric drive which includes an electric motor and a shaft which is driven thereby. A transmission of torque between the electric motor and the shaft can be brought about by at least one connecting element. A controllable locking device via which an interruption in the transmission of torque between the electric motor and the shaft can be brought about, is assigned to the connecting element. The use of the safety clutch in an electric drive for a wheeled vehicle is disclosed, a controller evaluating the transmission of torque between the electric motor and the shaft using a vehicle state, and when a fault state is detected the controller transmitting a control signal to the controllable locking device, as a result of which an interruption is brought about in the transmission of torque between the electric motor and the shaft.
