The invention provides a turning gear shifting connecting device for an automobile cab, which relates to a new gear shifting connecting field. In the gear shifting connecting device of the prior art, because a turning connecting rod simultaneously has functions of gear selecting and gear shifting, a main gear shifting rod has overlarge neutral hunting range in the gear selecting process, and the gear can not be accurately selected easily or even can not be shifted, thereby bringing inconvenience for a driver in operation and increasing the labor intensity of the driver. In the invention, a turning connecting rod (4) and a gear selecting and shifting arm (6) are respectively arranged but are not separated and are integrated into a whole; when a cab is turned up, the turning connecting rod (4) is separated from the U-shaped groove of the gear selecting and shifting arm (6) and turned up along the turning track of the turning connecting rod (4) along with a main gear shifting rod (1) by taking a turning connecting shaft (13) as a center, the other end of the turning connecting rod (4) is connected together with the gear selecting and shifting arm (6) through the turning connecting shaft (13), and the gear selecting and shifting arm (6) and other parts are kept in the original positions; and when the cab is turned down to return to the original position, the turning connecting rod (4) also returns into the U-shaped groove of the gear selecting and shifting arm (6), and the functions of gear selecting and gear shifting are recovered. The technical scheme of the invention can enable the main gear shifting rod (1) to successfully realize the operation of gear selecting and gear shifting in a very small range, has reliable operation and high efficiency, is convenient for a driver to operate, and simultaneously can reduce the labor intensity of the driver.
