Abstract
The utility model discloses a connecting tool for an automatic mechanical transmission and an engine, which comprises an extension bar and a bayonet, wherein the extension bar and the bayonet are rigidly connected to form a tool for adjusting the angle of an input shaft of the transmission. The tool outside extension rod for adjusting the angle of the transmission input shaft is pulled when the transmission input shaft of the gearbox is pushed into the splined hole of the clutch driven disc by using the connecting tool, so that the transmission input shaft rotates for a certain angle (the angle of one tooth) around the central axis, the transmission input shaft and the spline hub of the clutch driven disc are aligned by adjusting the angle, and the transmission input shaft and the spline hub are smoothly matched and installed to complete one working cycle. The utility model accelerates the production rhythm of the whole vehicle, improves the production efficiency, and simultaneously avoids the condition that parts of a clutch driven disc or a transmission input shaft are damaged due to incorrect assembly mode.

Background
In the current automotive industry, engines and transmissions are manufactured separately and then assembled together in an assembly shop. The automatic mechanical transmission is connected with an engine in a hoisting mode in an assembly site of a whole vehicle factory for butt joint assembly, but when the automatic mechanical transmission is connected with the engine in the hoisting mode in the assembly site of the whole vehicle factory, the condition that the spline of an input shaft of the transmission and the spline in a driven disc hub of a clutch are not good for teeth can occur, and the production beat and the driven disc hub can be influenced or even damaged. The automatic mechanical transmission can not be directly shifted by a rocker arm like a manual transmission, and then the gear alignment operation during installation is realized by rotating a flange plate.
Aiming at the situation that the input shaft of the transmission is not rotated well when the automatic mechanical transmission and the engine are hoisted, and the condition that the spline of the input shaft of the transmission and the internal spline of a clutch driven disc hub are not aligned well can occur, a mode that the transmission leaves a factory and is in gear pre-engagement is adopted in the same industry, but the transmission needs to be returned to a neutral gear before the engine is started on line in the whole vehicle. The gear is put into gear in advance, and then the neutral gear needs to be taken back before the engine is started to ignite, and an operation link and an operation tool need to be added in the whole loading process.
