Electric universal drive
Abstract:
In a universal drive with a rotatable or linearly movable drive member and piezo actuators supported on a carrier for acting on a leg supported on the drive member and moving the leg in a high-frequency stepping sequence in a drive direction, wherein the carriers are jointly supported on a stator by a pretension member which biases them elastically toward the drive member via an elbow lever mechanism including a first elbow lever and at least a second elbow lever which are both connected to an actuator by a coupling member and this arrangement is such that, with the first elbow lever stretched, the second elbow lever is kinked and vice versa.
