The paper presents theoretical dependences which allow to calculate the main parameters of a pneumatic actuator of a multi-step mechanical synchronized gearbox, depending on the parameters of an engine, a gearbox and conditions of traveling resistance during the synchronization process with alternating pressure and various air escapes into a pneumatic cylinder: critical and subcritical escapes at constant pressure. Results of theoretical investigations and bench tests were compared. Calculated values of synchronization time at separate stages and at the whole cycle of gear actuation differed from experimental data no more than by 10-25%.
