Abstract
An electric regulating device, particularly for a speed control device for motor vehicles, with a servomotor and a rotatably mounted element which actuates the regulating member, the rotatable element particularly being a cable pulley which stands in operative connection with the servomotor via a gearing and a coupling device containing an electromagnet. At least one of the gears of the gearing is radially and at an angle indirectly or moveably mounted, and is connected indirectly or directly with an armature, which in turn cooperates with the electromagnet. The gearing includes a gearwheel operatively coordinated to the at least one gear. A spring biases the armature with a spring force for moving the one gear out of engagement with the gearwheel when the electromagnet is without current. The spring cooperates with means for reducing the pretension of the spring in the neutral position of the regulating device.
