Abstract

The invention discloses an air outlet flange for an automobile engine. The air outlet flange comprises an air outlet flange body, the air outlet flange body comprises a base, and the base is pentagonal. A boss outwards protruding is arranged in the center of the base in the thickness direction of the base. A hole is formed in the center of the boss, foot margins are arranged at the upper end of the base and rectangular, connecting tables are arranged on the two sides of the base, and a first threaded hole is formed in each connecting table. A second mounting table is arranged on the base, a second threaded hole is formed in the second mounting table in the horizontal direction, and the outwards-protruding directions of the foot margins and boss are the same with those of the connecting tables. A buffering layer is arranged on the back portion of the base and comprises a rubber layer body connected with the back face, a wear-resisting layer body and a steel plate, the wear-resisting layer body is connected with the rubber layer body, and the steel plate is connected with the wear-resisting layer body. The invention further provides a production technique of the air outlet flange for the automobile engine. The air outlet flange for the automobile engine is simple in structure, convenient to machine, provided with a buffering structure and capable of improving the service life of pats, saving materials and reducing cost.
