SEMI AUTOMATIC PNEUMATIC GEAR BOX & LUBRICATION SYSTEM

Abstract: In this paper a gear shifting mechanism is designed and applied to make the shifting process faster and slow destructible for the driver. The new device must be safe, with small dimensions, low construction and maintenance cost. This project tries to better gear shifting process by using tool as: a laboring four speed gear box, two pneumatic double acting cylinders, two pneumatic two position five ways directional control device valves, an electrical motor, a belt, two pulleys, limit switches, push buttons, bulbs, a table (holder) and power supply. According to suggested gear shifting mechanism the driver can select the transmission gear ratio without moving his hands from the steering wheel by putting the gear shifting push buttons on the steering wheel. By Using this mechanism leaves to the driver the excitement of choosing the shifting moment.
