Hoecken linkage
Four-bar straight-line mechanism
From Wikipedia, the free encyclopedia
In kinematics, the Hoecken linkage (named for Karl Hoecken)[1] is a four-bar linkage that converts rotational motion to approximate straight-line motion. The Hoecken linkage is a cognate linkage of the Chebyshev linkage and Chebyshev's Lambda Mechanism.
Dimensions (unit length a):
Link 2: a
Link 3: any multiple of a
Link 1 (distance between ground joints): 2aThe linkage was first published in 1926.[2][3]
A generalization of the Hoecken linkage is Wittgenstein's rod.
