Hoecken linkage

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): 2a

The linkage was first published in 1926.^[2][3]

A generalization of the Hoecken linkage is Wittgenstein's rod.
