The shifting system of the present invention, in combination with the motor battery, constitutes a hybrid system in which the outer end of the output shaft of the gearbox is connected to the motor generator and is disposed on the panel provided with the control lever. In addition to the chutes of the neutral and the driving gears, an electric chute is formed from the neutral N position or the driving position D to the side direction, and a reverse chute is formed further at the end of the chute. The switch from the lower side of the control panel and the control line connected to the motor controller are connected to each other. The brake control line from the switch of the brake grip is also connected to the motor controller, and the motor controller is controlled by the bus and the motor generator. Connected, when the lever is moved from the driving position D position or the neutral position N to the electric position EV position, the engine working power is cut off, and the power of the motor controller that drives the motor generator is turned on when the lever is After the electric gear EV position is moved to the reverse gear R position, the vehicle can be controlled to reverse the vehicle, and the brake grip can be operated while driving, and the motor generator can generate the corresponding braking force and charge the battery.

Since the belt drive system in the above shifting system drives the output shaft through the one-way clutch, the engine resistance cannot be used for the deceleration braking. To overcome this deficiency, the driven gear of the driven gear is driven by the stepless drive in the gearbox. The sleeve has a brake force engagement disc that is pressed by the engaged spring and can be pressure-engaged with the side of the driven output gear. The engagement disc is connected to the shifting rocker arm via a fork and a wire, and is in a state where the shifting rocker arm is not controlled. In the stepless transmission state, the brake force engagement disc is in the engaged state on the driven output gear. When the shift rocker arm is controlled to shift to the direct shift state, the connected shift fork also drives the brake force engagement disc to leave the driven output gear.

In the above-mentioned direct transmission and belt infinitely variable transmission transmission system, the utility model mainly comprises two different structure clutch shifting modes of double cone top sleeve type and double clutch bearing type, and the shifting system is transferred from the belt infinitely variable transmission to the gear direct transmission. After that, not only the friction loss of the belt drive is eliminated, but the fuel consumption is correspondingly reduced, and at this time, the transmission efficiency of the transmission system is higher than that of the shift transmission, because four transmission gears are idling in a five-speed transmission. . In the shifting system of the present invention, since the V-belt is only used for starting acceleration, the replacement cycle of the belt is greatly extended, and there is no need to worry about the breakage of the belt during long-distance driving. The operation from the belt drive to the direct drive is very simple. After the start of the motorcycle acceleration, the motorcycle can be transferred from the stepless belt shifting drive to the direct gear state by simply stepping on the shift pedal. If the speed of the vehicle is low and the direct speed cannot be maintained, the speed control can be controlled by the speedometer and the plucking of the pick-up by hand can change the motorcycle from the direct transmission to the belt transmission state. The conversion operation of the two different transmission states is very easy. .

Thereafter, the ratchet block 127 on the swing lever 126 that has been put into the locked position is locked by the direct shift pawl 128 on the support (ie, the state shown in FIG. 2), and the shift pedal or the shift rocker arm top In the locked position. The set direct pawl 128 is connected to the release pad 130 via the cable 129. When the vehicle speed is reduced to a certain extent, the release flap 130 is operated to release the locked swing lever 126 and the jack 124 to no longer limit the shift. When the pedal or the shifting rocker is returned, the shifting system will be driven from the direct gear to the belt endless transmission state (ie, the state shown in FIG. 1), the shifting pedal 118, the shifting rocker 116 or the gear shifting described above. The fulcrum of the stop mechanism 124 and the swing link 126 are also connected to the buffer struts 134 of the hydraulic ram 133. When the shift pedal 118 is depressed, the buffer strut 134 is pulled outwardly, and when the locked shift pedal 118 or the shift rocker arm 116 is released, the buffer strut 134 is pushed back to the hydraulic cylinder 133. The return shock of the shift pedal 118 and its connecting member is correspondingly buffered.

When the vehicle speed is lower than the specified speed, the low speed switch 141 that is turned on will drive the armature 137 in the electromagnetic coil 136 to pull the direct gear pawl 128 back through the control line 142, so that the depressed shift pedal 118 returns to the In the starting position shown in Figure 11, the shifting system also returns from the direct transmission state to the belt endless transmission. In the active state, after the shift pedal 118 is returned, the power-saving switch 143 controlled by the shift pedal or the connected transmission member also disconnects from the electromagnetic coil 136.

Since the shifting double cone top sleeve of the shifting system of Fig. 1 is stopped in the intermediate position, a neutral state can be formed. For this type of shifting system, different gear locking mechanisms as shown in Fig. 16 are also provided, such as As can be seen in Figure 16, the shift pedal 118 is controlled by the gear lock mechanism provided, the swing arm 146 of the shift pedal is hinged to the jack 124 of the gear lock mechanism, and the swing lever of the jack and the support 145 When the lever 126 is hinged and the shift pedal 118 is in an uncontrolled belt endless transmission state, the connected jack 124 and the swing lever 126 are folded close to each other. When the shift pedal 118 is stepped to the direct position, the top The rod 124 and the swing rod 126 are brought open to an angle of approximately 180°. A rocker 127 is provided on the swing lever 126 that can be locked by the direct pawl 128 and the neutral pawl 155.

The pull rod 147 connected to the direct gear pawl 128 is placed in the electromagnetic coil 136, and the armature 137 on the pull rod can also be controlled by the electromagnetic coil, and the electromagnetic coil is passed through the power saving switch 143 and the low speed controlled by the vehicle speed centrifuge 138 or the speedometer. The switch 141 is in communication with the power source 140. The line from the power-saving switch 143 is also in communication with the power source 140 via the manual low-speed switch 163. The rocker arm 156 on the neutral pawl 155 drives the neutral lock block via the link 157 and the transmission arm 158. 159. When the lever 153 is moved to the neutral position N as shown in FIG. 16, the driven arm 150 moves the neutral pawl 155 suspended in the intermediate position to the position where the lock is actuated. After the shift pedal 118 is stepped down to move from the belt endless transmission position to the neutral position in the middle of the stroke, the shift pedal 118 moved to the neutral position is blocked by the raised neutral lock block 159, and The ratchet block 127 on the associated swing lever 126 is also blocked by the neutral pawl 155 so that the shift pedal 118 cannot be returned to the neutral position, thereby allowing the connected shifting double cone top cover 26 to be parked on the belt. And the intermediate neutral position where the direct clutches 45, 56 are not controlled to be engaged, so that the engine is safely started or parked. The shift pedal or the swing lever in the neutral position also drives the switch 161 to be turned on via the trigger member 160, so that the set neutral light 162 emits a neutral indication. When the shift lever 153 is returned to the position of the traveling gear D shown in Fig. 11, the released shift pedal 118 and the ratchet block 127 of the swing lever 126 are spring-loaded to return to the initial state of the belt endless drive. After the control lever is in the driving position, when the vehicle speed exceeds the limit, it can be transferred to the direct gear. When the shift pedal 118 is depressed, the shifting double cone sleeve 26 is released, and the belt clutch is released and the direct clutch is engaged. The pawl 128 locks the ratchet block 127 of the swing lever 126 that is brought to the open position, thereby also stopping the depressed shift pedal 118 in the direct position. When the uphill resistance is large or the vehicle speed is lower than the prescribed limit, as shown in FIG. 18, the parallel manual low speed switch 163 can be operated or the low speed switch 141 can be turned on by the vehicle speed centrifuge or the speedometer, and released by the electromagnetic coil 136. The ratchet block 127 on the locked swing lever 126 returns the associated shift pedal 118 from the direct position to the belt infinitely variable transmission state.

When driving in urban roads, it often encounters traffic jams when stopping and stopping. At this time, driving with the engine under low load will cause a large fuel waste. To adapt to this driving state, Figure 19 shows a motor including The hybrid arrangement of the battery can be seen from the figure. The solution is based on a shifting system using a shifting double cone top sleeve. The outer end of the output shaft 66 of the gear box 65 is connected to the motor generator 164, and the control rod 153 is provided. On the panel 165, in addition to the neutral and driving In addition to the chute 166 of the gear, an electric chute 167 is formed from the neutral N position or the driving position D to the side direction, and a reverse chute 168 is formed further at the end of the chute. The control line 170 from the switch 165 under the control panel and the control line 170 is connected to the motor controller 175. The brake control line 174 from the switch 173 of the brake grip 172 is also in communication with the motor controller 175, the motor controller The control bus 171 is connected to the motor generator 164. When the control lever 153 is moved from the driving position D position or the neutral position N position to the electric position EV position, the engine operating power is cut off, and the power of the motor controller 175 that drives the motor generator is turned on. When the control lever 153 is moved from the electric gear EV position to the reverse gear R position, the vehicle can be controlled to reverse. When the brake grip 172 is operated while driving, the motor generator can generate a corresponding braking force and charge the battery 177.

When the shifting system of the present invention is in the belt shifting state, the power of the engine is driven by the belt after the belt shifting, and the driven output gear is driven by the one-way clutch. Therefore, the engine resistance cannot be used to decelerate when the brake is decelerated. In order to overcome this deficiency, a brake force engagement disc 178 controlled by the shifting rocker arm 116 is added to the shifting system in FIG. 2. As shown in FIG. 2, the driven gear 15 driven by the infinitely driven gear in the gear box 65 is shown in FIG. The sleeve 16 is provided with a brake force engagement disc 178 which is pressed by the engagement spring 176 and is press-engageable with the side of the driven output gear 67. The engagement disc is connected to the shift rocker arm 116 via the fork 179 and the cable 180. . When the shift rocker arm is not controlled and is in the endless transmission state, the brake force engagement disc 178 is pressed against the driven output gear 67 so as to be decelerated by the resistance of the engine.
