Dreigelenks

Dreigelenks is a term of German origin that translates to "three joints." In the context of engineering and mechanics, it refers to a specific type of kinematic chain or linkage consisting of three rotational joints. This configuration is fundamental in the design of various machines and structures where controlled movement and articulation are required.

The simplest form of a dreigelenks is a planar mechanism. It typically involves three links connected by revolute joints. This arrangement allows for a range of motion that can be used for tasks such as transferring power, changing direction of motion, or creating specific output movements from a given input. The specific configuration and lengths of the links determine the overall behavior and capabilities of the dreigelenks.

Dreigelenks mechanisms are employed in a wide array of applications. For instance, they can be found in robotic arms, where multiple dreigelenks segments create the necessary degrees of freedom for manipulation. In mechanical presses, a dreigelenks can be used to amplify force and achieve a controlled pressing stroke. They also appear in simpler mechanisms like certain types of linkages used in agricultural machinery or vehicle suspensions. The versatility of the three-joint structure makes it a foundational element in mechanical design.
