electrical gear shifting using solenoid ppt
A semi-automatic electric gear shifting apparatus for use in shifting gears in gear boxes of motorcycles and the like gear boxes wherein gears are shifted by rotating a spindle operably connected to a ratchet type gear shifting means. The said gear shifting apparatus comprises a lever arm connected at one end thereof to said spindle and connected at its other end to a toe pedal means. An actuating rod is operatively connected to said toe pedal, and the rod is reciprocated to move said lever arm and thus said spindle by a solenoid which is actuated selectively by a pair of push button switches mounted on the handle bar of the motorcycle.An electric solenoid shifter for motorcycles for clutchless shifting of the motorcycle by pushing a button mounted on the handlebars of the motorcycle includes a solenoid mounting plate for securing a solenoid to the motorcycle and a micro-switch which is operably linked to the solenoid and mounted on the motorcycle. A cable clamp for securing a solenoid cable is secured to the solenoid and a spring is secured to the cable clamp and to a solenoid cable bracket. A locknut is secured to the solenoid cable bracket and a cable adjuster element is secured to the locknut. A gear shifter cable bracket assembly is operably secured to the solenoid cable and to a clevis, with the clevis being mounted to the motorcycle. An electric interrupt element for controllably interrupting the ignition system of the motorcycle is secured to the motorcycle and operably linked to the micro-switch and to a toggle switch. A control button is secured to the handlebars of the motorcycle for controlling the solenoid. The control button is operably linked to a relay element and to the solenoid.
