Steuerarm

Steuerarm is a mechanical lever used to control or transmit motion and force from a drive source to a recipient component. The term is common in German engineering and appears in contexts ranging from vehicle steering to automated control linkages. A Steuerarm typically acts as a lever that changes direction, magnitude, or type of motion; for example, it can convert rotational movement from a crank or motor into a linear displacement or into an angular movement at a connected node.

In automotive steering systems, a Steuerarm is part of the steering linkage that connects the steering mechanism to the wheel hub or knuckle. It is mounted on a pivot point and transmits the steering input to the wheel, producing the steering angle. The precise arrangement depends on the vehicle design; in some layouts it forms part of the steering knuckle, in others it is a link in the rack-and-pinion assembly. Commonly, a Steuerarm is equipped with joints (ball joints or hinge pins) to allow for steering motion while accommodating suspension movement.

In other machinery, Steuerarm linkages are used to actuate valves, clamps, or other actuated devices where a cam, gear, or linear actuator drives the arm. They are found in control mechanisms, automation equipment, and various mechanical transmissions where compact, robust lever action is required.

Steuerarme are usually made from steel alloys or aluminum, designed to withstand bending and fatigue. The joints are critical points and require appropriate clearances, lubrication, and secure fastening. Overload, misalignment, or wear at joints can lead to looseness, increased play, or premature failure.

Die Bezeichnung leitet sich von Steuer (control/steering) und Arm (arm/lever) ab. See also: Lenkung, Kipphebel, Kurbel.
