The Study of the Synchronization Process in the Gearbox with Automatic Control

摘要

The paper presents theoretical dependences to calculate the main parameters of the pneumatic actuator of the multi-stage manually synchronized transmission depending on the parameters of the engine, the transmission and conditions of running resistance during the synchronization process at alternating pressure with different types of the air discharge into the pneumatic cylinder: critical, subcritical and at constant pressure. Comparison of results theoretical and experimental studies on the test stand shows that the calculated values of synchronization time on certain stages and throughout the cycles of the transmission shifting differ from the experimental data by 10-25% maximum.
