Examples

As shown in fig. 3, it can be seen from the structural view of the 12-gear AMT transmission, which is composed of a front-mounted splitter group transmission 21, a centrally-mounted main transmission 22 and a rear-mounted splitter group transmission 23.

The main transmission 22 is composed of 3 forward gears and 1 reverse gear.

The multiple gear group transmission 23 consists of 2 gears.

As can be seen from the 12-gear AMT transmission structure diagram, the increase of the forward gears is a result of the main transmission 22 expanding through the splitter sub-transmission 21 and the doubler sub-transmission 23. The main transmission 22 has only 3 forward gears, and is expanded to 6 gears through the front-mounted auxiliary transmission 21, and is expanded to 12 gears through the rear-mounted auxiliary transmission 23.

An axle 18 mounts the transmission assembly at one end thereof adjacent the engine, and engine power is input by the axle 18.

The secondary shaft 20 is arranged on one side of the transmission assembly, which is far away from the engine, and transmits the force of the normally meshed gears on the intermediate shaft to the rear-mounted double-gear auxiliary transmission 23, and then power is output.

The double middle shafts 19 are provided with a plurality of pairs of gears which are respectively meshed with the gears on the first shaft 18 and the second shaft 20 correspondingly, and power can be transmitted through the gears on the two middle shafts 19 simultaneously.

And the electromagnetic valve 1 of the rear auxiliary box is connected into a rear auxiliary box gear shifting cylinder module 12 of the AMT gear selecting and shifting actuating mechanism to control the cylinder to act.

And a rear auxiliary box shifting fork on the rear auxiliary box gear shifting cylinder module 12 acts on a synchronizer of the double-gear auxiliary transmission 23 to realize gear shifting.

The main box shift fork of the main box shift cylinder module 14 acts on a synchronizer of the main transmission 22 to realize shifting.

The TCU module 4 receives the gear shifting signals, the TCU module 4 processes the received gear shifting signals, and sends control signals to the electromagnetic valves to control the cylinders to act, so that the purpose of gear shifting is achieved.
