In
kinematics, the Hoecken linkage (named for
Karl Hoecken)
is a
four-bar linkage
In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed-chain movable linkage. It consists of four bodies, called ''bars'' or ''links'', connected in a loop by four joints. Generally, the joints are config ...
that converts
rotational motion
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional ...
to approximate
straight-line motion. The Hoecken linkage is a
cognate linkage of the
Chebyshev linkage
In kinematics, Chebyshev's linkage is a four-bar linkage that converts rotational motion to approximate linear motion.
It was invented by the 19th-century mathematician Pafnuty Chebyshev, who studied theoretical problems in kinematic mechanis ...
and
Chebyshev's Lambda Mechanism.
The linkage was first published in 1926.
A generalization of the Hoecken linkage is
Wittgenstein's rod.
