  • Actuating drive for bidirectional actuator
    Patent number: 8490605
    Abstract: An actuating drive for a bi-directionally adjustable actuator for at least on of an exhaust gas recirculation device and an exhaust gas turbocharger. The actuating drive includes an electric motor; a toggle lever, which articulates with the actuator via a first toggle lever bearing; and a gear mechanism, connecting the electric motor with the toggle lever, wherein the gear mechanism includes a toothing element on an output side mounted in a pivot bearing, wherein the toggle lever is articulating mounted via a second toggle lever bearing, wherein in a starting state of the actuating drive is associated with a starting position of the actuator, and wherein an acute angle exists between a first straight line extending through the first toggle lever bearing and through the second toggle lever bearing, and a second straight line extending through the pivot bearing and through the second toggle lever bearing.
