ABSTRACT:
A gear shifting mechanism for a transmission, capable of driving the gearshift drum of the transmission for turning in both a shift-up direction and a shift-down direction by operating a switch or a valve. A sector gear is formed on a gearshift arm fixed to a gearshift spindle to drive a gearshift drum. A driving gear, engaged with an idle gear engaged with the sector gear, is fixed to the rotary shaft of a pneumatic rotary actuator. The pneumatic rotary actuator is attached to the transmission case of a transmission, and compressed air is supplied into either a first pressure chamber or a second pressure chamber of the rotary actuator through a solenoid selector valve to turn the rotary shaft in either the normal direction or the reverse direction. The present invention provides an auxiliary gear shifting system which enables gear shifting operation without the operator using his/her foot. An actuator operatively connected to a gearshift arm is driven by compressed air reserved in a main frame and supplied thereto through an air valve and a pneumatic switch. Part of the compressed air supplied to the actuator is supplied to a pressure switch to make an ignition unit reduce the output of the engine temporarily during the operation of the actuator. The pneumatic switch can be remote-controlled by an operator's hand through a remote-control wire by operating a switch lever disposed near the grip of a handlebar.
