(5) embodiment
Below just by reference to the accompanying drawings, just the present invention is described further;
For manual clutch's automatic gear shifting system, in conjunction with schematic representation 1 of the present invention, 2; At normal travelling state (non-gearshift state), solenoid valve is in normally open, the cam of automatic gear shift apparatus and gearshift driving lever position as shown in Figure 2.Under the effect of clutch spring, clutch is in bonding state, and by clutch cable, clutch line wheel, sliding axle, bearing, throttle line wheel is pulled to the top, and bearing is against on the cam generating circle.When controller by to the analysis of each sensor signal, when determining to shift gears, the reducing motor that controller is at first controlled automatic gear shift apparatus rotates, and drives cam and shift lever axis thus and rotates.The rotation of cam is ordered about bearing drive sliding axle and is moved down along chute, makes clutch line wheel and throttle line wheel together move down.Moving down of throttle line wheel makes throttle line be released, and throttle reduces, engine retard thereby make.Moving down of clutch line wheel, by the clutch line with clutch separation.The lift of cam has guaranteed that the release fully of throttle separates with the thorough of clutch.The angle of the arc groove of shift lever axis and driving lever projection has guaranteed that in cam lift the end face of shift lever axis circular arc can not prop up the driving lever projection, and therefore the gearshift driving lever is motionless in cam lift.When the cam lift end, the further rotation of cam makes the end face of shift lever axis circular arc prop up the driving lever projection, drives the gearshift driving lever and rotates with shift lever axis.The rotation of gearshift driving lever drives the gearshift connecting rod mechanism movement, and the gearshift indexing mechanism by speed changer inside, axial cam mechanism etc. realize the gearshift action of speed changer.Angular displacement sensor in the automatic gear shift apparatus is monitored the position of shift lever axis constantly, and after finishing the gearshift action, controller is in closed condition with solenoid valve, the UNICOM in chamber, the damping oil cylinder left and right sides is closed, thereby make clutch remain on separated state.The reducing motor of controller control simultaneously starts the backhaul of shift lever axis and cam.Returning of shift lever axis restored the position of gearshift linkage mechanism.The returning of cam makes the proud release of clutch cable, and throttle line is restored.In return stroke, controller is by the keying of control solenoid valve, and the release rate of solenoidoperated cluthes makes the clutch smooth and steady combination.Controller is by angular displacement sensor monitoring shift lever axis and cam reposition.
For the automatic gear shifting system of automatic clutch, in conjunction with schematic representation 3 of the present invention, 4; At normal travelling state (non-gearshift state), the cam of automatic gear shift apparatus and gearshift driving lever position as shown in Figure 4.Cam withstands on the below with sliding axle, bearing, throttle line wheel.When controller by to the analysis of each sensor signal, when determining to shift gears, the reducing motor that controller is at first controlled automatic gear shift apparatus rotates, and drives cam and shift lever axis thus and rotates.The rotation of cam has discharged the bearing thrusting action, under the effect of throttle return spring, drives sliding axle by throttle line and moves up along chute, and the throttle line wheel is together moved up, and makes throttle line be released, and throttle reduces, engine retard thereby make.The lift of cam has been guaranteed the release fully of throttle.The angle of the arc groove of shift lever axis and driving lever projection has guaranteed that in cam lift the end face of shift lever axis circular arc can not prop up the driving lever projection, and therefore the gearshift driving lever is motionless in cam lift.When the cam lift end, the further rotation of cam makes the end face of shift lever axis circular arc prop up the driving lever projection, drives the gearshift driving lever and rotates with shift lever axis.The rotation of gearshift driving lever drives the gearshift connecting rod mechanism movement, and the gearshift indexing mechanism by speed changer inside, axial cam mechanism etc. realize the gearshift action of speed changer.Angular displacement sensor in the automatic gear shift apparatus is monitored the position of shift lever axis constantly, and after finishing the gearshift action, controller control reducing motor starts the backhaul of shift lever axis and cam.Returning of shift lever axis restored the position of gearshift linkage mechanism.Returning of cam makes the throttle line wheel be pushed up back original position, throttle home position.In return stroke, controller is by angular displacement sensor monitoring shift lever axis and cam reposition.
