Pneumatic gear-shifting control device of automatic transmission

The invention discloses a pneumatic gear-shifting control device of an automatic transmission. The pneumatic gear-shifting control device of the automatic transmission is characterized by at least comprising a gear shifting cylinder and a position selecting cylinder. The gear shifting cylinder and the position selecting cylinder are installed on a first support and a second support in an orthogonal mode in the space, and the first support and the second support are arranged on one side of a gearbox. One end of the gear shifting cylinder is fixedly connected with the first support, and a gear selecting head which is used for selecting the position is arranged at the other end of the gear shifting cylinder. One end of the position selecting cylinder is fixedly connected with the second support, and a switching head which is used for shifting gears is arranged at the other end of the position selecting cylinder. The gear shifting cylinder and the position selecting cylinder communicate with a pneumatic control s
