The invention discloses an auxiliary regulating device of travelling airflow. The travelling airflow comprises two tail wing structures, an airflow path and a hydraulic pipeline, wherein the tail wing structures are positioned at the tail end of the airflow path; each tail wing structure comprises a main wing, an assistant wing and a driving mechanism; the main wings are positioned under the assistant wings, and the front ends of the assistant wings are close to the tail ends of the main wings; end plates are respectively arranged at the same side ends of the main wings and the assistant wings, the main wings are fixedly connected with the end plates, and the assistant wings are connected with the end plates in a rotating manner; each of the driving mechanisms comprises an assistant wing cylinder and a base, wherein rotary assistant cylinders are arranged on the bases; the hydraulic pipeline comprises a hydraulic pump, an assistant wing pipeline for closing and opening the two assistant wing cylinders at the same time, and a rotary assistant pipeline for separately closing and opening each rotary assistant cylinder; a plurality of bar-shaped through holes in parallel arrangement are formed in the positions above the assistant wings on the front sides of the end plates. The invention aims to provide a device which can regulate lower pressure and air resistance on the left side and the right side of the tail of an automobile so as to improve the adhesion property of the automobile and reduce the load of tires.
