Abstract
The goal is to establish an actuating logic, the minimum necessary actuators and electrical driving unit. On the power train, a sequential self-acting, quadratic cycle Huffmann type device are implemented to act the clutch and the levers of gearbox to shift speed.
The number of actuators was minimized by using a combinational logic, which with the help of a “step by step” relay circuit was build-up. The acting energy is a pneumatic one, which activates a number of command electrovalves for pneumatic cylinders. The conclusions will be validated by experimental researches to the engine’s test bench.
Keywords: actuating, logic, gear box, electrovalves, test bench.
