Abstract
An elliptical exercise machine comprises a frame, two transmission rods, two stepping rods, wherein the frame is provided with a driving wheel and two sides of the driving wheel are respectively provided with a crank. One ends of the two transmission rods are connected to two cranks. The two stepping rods are connected to two transmission rods. Another end of each stepping rod is pivoted with a towing rod. Each towing rod is pivoted to the frame. Relatively elliptical orbits are formed through the two stepping rods driven by the two swing arms and the two transmission rods. When the two stepping rods reach a left acme and a right acme of each elliptical orbit, the two towing rods further tow the stepping rods corresponding to each other to generate a quick return effect so that elliptical orbit motion can be smoother.
