Figure: Coupler Rod of Locomotive 

(Link AD = Link BC = Crank Link CD = Coupling Rod Link AB = Fixed Link = Frame)

Working of Coupler Rod of Locomotive: It is an example of Double Crank Mechanism in which, Links AD and BC (having equal length) act as cranks and are connected to the respective wheels. Link CD acts as a coupling rod and link AB is fixed in order to maintain a Constant center to center distance between them. This mechanism is meant for transmitting rotary motion from one wheel to the other wheel.
