PROTOTYPE DEVELOPMENT OF WIRELESS PNEUMATIC GEAR SHIFTER

Conventional design of transmission gear shifter is basically consists of mechanical linkage of gear lever attached on the side of motorcycle engine with pivot directly connected to the gear shifting mechanism. Shifting up and down of gear positions are performed by moving foot or toe upward and downward on the lever respectively. For disable rider (rider requires special need), shifting gear for manual transmission type of motorcycle with or without clutch system is difficult. In this research, a pneumatic gear shifter is designed and fabricated. It consists of pneumatic circuit with actuator, tanks and air compressor. The movement of gear lever is performed by the pneumatic actuator. Pneumatic tanks are installed to achieve optimum pressure. It also controlled by wireless system for convenient purpose and buttons installed at the handle. Simple experiment is performed to measure the force for each gear position.
