When vehicle speed per hour during greater than 5 kilometers/hour, the time speed sensors send light gear shifting signal to controller.Receive the power circuit of the closed easily gearshift of the controller button of this signal.When chaufeur need be shifted gears, need not to depress as usual pedal of clutch, press light gearshift button when stopping the handle gearshift but only need be in one's hands.At this moment, control cock is connected, and the high-pressure medium of high-pressure medium jar is through the control cock bilateral check valve of flowing through, and injects clutch booster through the bilateral check valve, thereby disengages the clutch, and realizes easily gearshift.After gearshift finishes, unclamp light gearshift button, the UNICOM of control cock cut off high medium jar and bilateral check valve.At this moment, the high-pressure medium in the clutch booster cylinder enters by the bilateral check valve and reclaims the loop, clutch booster push rod return, and power-transfer clutch engages again, and easily shift process is finished.

When controller from the time speed sensors when not receiving the speed of a motor vehicle greater than 5 kilometers/hour signal, controller cuts off the easily power circuit of gearshift button, thereby can't easily shift gears.In other words, under this speed, can only pass through pedal of clutch operated clutch, the infringement of so just having avoided maloperation that shifting system is caused.

Preferably, described high-pressure medium is an air, like this, just can save described recovery loop, and after finishing gearshift directly with in the clutch booster the high pressure gas exhaust to atmosphere.A kind of replacement is that described high-pressure medium is an oil.In this case, described high-pressure medium jar is the high pressure oil tank, and the high pressure oil tank is led in described recovery loop.

In a preferred embodiment, described controller also has an indicator lamp, when controller from the time speed sensors speed per hour that receives vehicle surpass 5 kilometers/hour, thereby during the closed easily gearshift of controller button, this indicator lamp is lighted, and can shift gears by light gearshift with the indication chaufeur.And when controller from the time speed sensors speed per hour signal that receives for less than 5 kilometers/hour the time, this indicator lamp extinguishes, and can not easily shift gears with the indication chaufeur.

Preferably, described control cock is an electromagnetic valve, more preferably a two-position three way magnetic valve.

Preferably, described light gearshift button is arranged on the shift handle, is convenient to operation like this.

Obviously, light gearshift of the present utility model has improved the simplification and the traveling comfort of driver's operation widely, simultaneously, since when speed per hour during greater than 5 kilometers this system avoided traditional clutch gear-shift operating mechanism, by light gearshift button direct control gas circuit, the separation that realizes power-transfer clutch with engage, so can also improve the service life of clutch gear-shift operating mechanism greatly.
