Design and test of pneumatic AMT control device

To realize the target of shifting gears rapidly and smoothly, the paper puts forward a kind of pneumatic AMT control device design project in allusion to a certain type of tracked armored vehicles´ structure characteristics. According to the project, the paper has a refit on the tracked armored vehicle and conducts a test, it is verified that the new designed device works stably and reliably, achieves the target to shift gears at a high pressure, keep the gear at a low pressure and shift gears in a short time, well satisfies the request of the vehicle´s automatic transmission system.
