AN ELECTRO-PNEUMATIC CLUTCH ACTUATOR

Abstract: The process of managing the clutch of a vehicle is an integral component of a driver’s work and requires spe-cific skills and physical effort, especially for drivers of trucks and buses. One way to simplify the clutch control process for these types of vehicles involves using a developed design of an electro-pneumatic clutch actuator. The particularity of the proposed clutch actuator lies in the utilization of an accelerator pedal valve in its construction, enabling the provision of necessary operational parameters under various working conditions. The construction of the accelerator pedal valve used in the electro-pneumatic clutch actuator has been enhanced by incorporating a throttle that combines its control and power cavities. The presence of this aperture between the cavities of the accelerator pedal valve allows for quicker pressure equalization within them, thereby improving the precision of the actuating mechanism’s shaft positioning. To validate the functionality of the proposed accelerator pedal valve design, a mathematical model describing the opera-tional process of the electro-pneumatic clutch actuator was created. Through mathematical simulations, the perfor-mance of the accelerator pedal valve was investigated based on the duration of the controlling impulse supplied to the respective electro-pneumatic valve. To verify the accuracy of the mathematical model, the obtained results were com-pared with experimental research outcomes. The obtained numerical values for the duration of the controlling impulse leading to the operation of the accelerator pedal valve in the proposed design were determined based on the results of the mathematical modeling of operational processes. These findings highlight the distinctiveness of the proposed con-struction compared to previously known designs. Numeric values for the duration of the controlling impulse that triggers the operation of the accelerator pedal valve in the proposed construction were obtained.
