The invention discloses a transmission system of a tricycle. The transmission system comprises a front frame and a rear frame, wherein the front frame comprises a crank chain wheel and a first-stage flywheel which are connected by a front frame chain, and the first-stage flywheel is fixedly connected to the front frame through a first-stage flywheel shaft; the rear frame comprises a rear frame flywheel and a second-stage flywheel which are connected by a rear frame chain; the second-stage flywheel is fixedly connected to the rear frame through a second-stage flywheel shaft, and the rear frame flywheel is used for driving a rear frame wheel; the first-stage flywheel shaft and the second-stage flywheel shaft are connected through a universal telescopic shaft. The technical scheme has the advantages that the front frame and the rear frame are in relatively independent rotation; in transition the universal telescopic shaft is adopted as well as in torque transmission; two driving functions of the front frame and the rear frame are not affected by spiral distortion of a chain of the transmission system due to the variation of a rotation angle and a distance when the front frame and the rear frame rotate in the radial direction; the chain transmission is still kept stable when the front frame rotates and swings, and the comfort of a rider is increased.
