The invention discloses a cardan universal joint type flap transmission mechanism. The cardan universal joint type flap transmission mechanism comprises a rotary block, connecting rods, swing arms, transmission rotary shafts, cardan universal joint assemblies and rolling bearings. The two ends of the rotary block are hinged to the connecting rods respectively. The connecting rods are hinged to one ends of the swing arms. The other ends of the swing arms are connected with the transmission rotary shafts. The rolling bearings are installed at the two ends of the transmission rotary shafts in an interference fit mode. The transmission rotary shafts are split into two sections for connection according to requirements through the cardan universal joint assemblies. The mechanism can effectively solve the problem that transmission accuracy is affected by small wing space, the long transmission path and wing bending deformation, can be widely applied to occasions with limited installation space and long-distance transmission, and is driven by a single power source, motion synchronism of a left flap and a right flap is good, the deflection symmetry of the flaps in the forward direction and the reverse direction is good, and response is reliable. Through refitting, the mechanism can be universal in design according to different types and different airload conditions.
