Embodiment Construction

[0036] according to Figure 1~Figure 6 , the actuating drive 1 includes an actuator 4 for generating a driving force, a force transmission device 5 and a toggle lever 6 , and the actuating element 3 , which can be adjusted bidirectionally according to the double arrow 2 , can be driven by means of the actuating drive 1 . The actuator 4 is, for example, an electric motor. The force transmission device 5 is in the example a gear train. The toggle lever 6 is connected in an articulated manner to the actuation element 3 via a first toggle lever joint 7 . exist Figure 1~Figure 3 In the embodiment shown, the actuating element 3 can be, for example, a valve element 8 which has a valve body 9 and which is adjusted relative to a valve seat 10 . The actuating drive 1 can be used, for example, in an exhaust gas recirculation valve of an exhaust gas recirculation device of an internal combustion engine, in particular a motor vehicle. Then, in order to set the exhaust gas recirculatio...

Abstract

The invention relates to an actuating drive (1) for a bidirectionally adjustable actuating element (3), in particular for an exhaust gas recirculating device or for a turbocharger, comprising an actuator (4) for generating driving forces, comprising a toggle lever (6) that is connected to the actuating element (3) in an articulated manner via a first toggle lever joint (7), and comprising a force transmitting arrangement (5) that connects the actuator (4) to the toggle lever (6) in order to transmit forces. An output-side output element (11) of the force transmitting arrangement (5) is pivotably mounted on a support housing section (12) of the actuating drive (1), and the toggle lever (6) is connected to the output element (11) in an articulated manner via a second toggle lever joint (13). Wear reduction can be achieved using a transverse support (42) that supports the toggle lever (6) and / or the actuating element (3) on a guiding housing section (18) of the actuating drive (1) in a direction of support (17) that is oriented transversally to the direction of movement (2) of the actuating element (3).

Description

technical field [0001] The invention relates to an actuating drive for a bidirectionally adjustable actuating element, in particular for an exhaust gas recirculation device or for an exhaust gas turbocharger, which actuating drive has the features of the preamble of claim 1 . The invention also relates to an exhaust gas recirculation valve provided with the actuating drive, and an exhaust gas turbocharger provided with the actuating drive. Background technique [0002] An actuating drive of this type is known from DE 10 2007 054 769 A1. The actuating drive comprises an electric motor designed as an actuator for generating a driving force and a toggle lever connected to the actuating element by means of a first toggle lever joint. A force transmission device is also provided which connects the actuator to the toggle lever for force transmission. The output member of the output end of the force transmission device is pivotally mounted on the supporting housing part of the ac...
