Be engaged with driven half cycle gearwheel 30 with the complete all small gears 25 of active, the number of teeth of driven half cycle gearwheel 30 is times of the complete all small gears 25 of active, so when initiatively complete all small gears 25 rotated a week, driven half cycle gearwheel just rotated half-turn, promptly 180 °.In the half cycle of 180 ° of rotations, 310 ends of speed changer pull bar 31, promptly speed changer pull bar positioning shaft 32 arrives the B point by the A point, finishes by bottom gear and changes top gear into.When clutch linkage group cam 20 rotated a week again, driven half cycle gearwheel 30 rotated half-turn again, and this moment, speed changer pull bar positioning shaft 32 returned the A point by the B point, was promptly returned again by top gear and changed bottom gear into, thereby reach the gear shift effect.
When initiatively complete all small gears 25 rotate, driven half cycle gearwheel 30 also can rotate, but on the cooperation operative relation according to clutch and speed change gear, when clutch when still separate fully at the end, the shift gear is not fill (technical requirements of gearbox system) of being permitted to carry out mobile gear shift, only separate back (actuator and wheel are thrown off the back fully) fully at clutch, the shift gear just can mobile gear shift.But driven half cycle gearwheel 30 and the complete all small gears 25 of active are to rotate synchronously, so, the design at first enters quick separated state (seeing 0 ° → 15 ° among Fig. 3) in the very first time of cam running, clutch is separated in the shortest time fast, is to separate the court of a feudal ruler period (seeing 15 ° → 19515 ° among Fig. 3) then.Be provided with speed changer pull bar positioning shaft 32 on synchronous operated driven half cycle gearwheel 30, axle point is positioned at the top of driven half cycle gearwheel 30 central cross line horizontal lines, and with central shaft shape at an angle alpha 1, its value is 10 °-15 °.Speed changer pull bar positioning shaft 32 is 10 ° of-15 ° of rotations to the angle [alpha] 2 of sense of rotation when driven half cycle gearwheel 30 rotates, when forwarding α 2 to by α 1, speed changer pull bar positioning shaft 32 just up and down with driven half cycle gearwheel 30 equivalent runnings, and for same speed changer pull bar 31 the other ends 311, in the technical requirements scope of speed change system, the axle point of pull bar positioning shaft 32 does not almost produce move left and right, meets the technical requirements of speed change system.
When driven half cycle gearwheel 30 was rotated further, angle of rotation changed, and speed changer pull bar 31 morals 311 end points that connect gearbox begin to produce laterally and move, and the clutch of this moment enters complete separated state the sixth of the twelve Earthly Branches.At this moment, change gear begins mobile gear shift.When driven half cycle gearwheel 30 was rotated further about 165 °-170 ° of angle, gear shift finished.This moment, cam arrived clutch adapter section (195 ° → 0 ° position) the sixth of the twelve Earthly Branches, and clutch begins in conjunction with also thoroughly combination.The driving shaft 26 of clutch linkage group cam 20 is finished the one-period running at this moment, and control motor and speed reducer group 4 shut down.
Working principle of the present invention is:
After the control motor was received instruction (trigger signal), the control motor began to rotate, and drives reduction gearing, reaches actual gearshift after the deceleration and requires speed (about 70-85 rev/min), and the output terminal of control motor and speed reducer group 4 contacts with driving shaft 26.Method with key or floral axis key on the driving shaft 26 is fixed with clutch linkage group cam 20 and the complete all small gears 25 of active.
When driving shaft 26 rotates, drive clutch linkage group cam 20 and the complete all small gears 25 of active rotate together, clutch linkage group cam 20 whenever turns around and is one-period, when whenever turning around, driving shaft 26 is under controls such as limit switch, (or photoelectric control or the control of dried spring), and revolution can stop after the moving week automatically.
Under the situation of rotating a week, clutch linkage group cam 20 promotes 21 motions of control clutch pull rod cam arm.Pass through cam arm coupling shaft 23 with 211 ends of clutch pull rod cam arm 21, be connected with clutch pull rod 24; The connection joint of flexible rotation is equipped with in two terminations of clutch pull rod 24.241 ends of clutch pull rod 24 connect the clutch on the electric vehicle, along with one week of rotation of cam 20, promptly 360 °, with the quick segregation section of finishing clutch with separate the court of a feudal ruler period, adapter section is to a series of programs of complete adapter section gradually, and it is 360 ° that clutch linkage group cam 20 whenever turns around.
Fixedly mounted a complete all small gear 25 of active on driving shaft 26, clutch linkage group cam and the complete all small gears 25 of active rotate together with driving shaft 26.
In a side of complete all small gears 25 initiatively, a driven half cycle gearwheel 30 has been installed, both runnings that are meshing with each other.
The number of teeth of driven half cycle gearwheel 30 is times of the complete all small gears 25 of active, so when initiatively complete all small gears 25 rotate a week (360 °), driven half cycle gearwheel 30 just rotates half-turn (180 °).
In the half cycle of 180 ° of rotations, the axle of pull bar positioning shaft 32 arrives B point (changing top gear into by bottom gear) by the A point.
When the control motor is received instruction again (sending a trigger signal), the control motor begins to rotate, cam 20 restarts to rotate, the another cycle begins, cam 20 rotates a week again, cam promotes to control clutch pull rod cam arm 21 again, finish again clutch quick segregation section, separate the court of a feudal ruler period and be attached to a series of programs of complete adapter section gradually.Different is: last one-period is that the axle of speed changer pull bar 31 arrives B point, (changing top gear into by bottom gear) by the A point.And being the B point, this one-period returns A point (return change bottom gear into by top gear).In other words:
By the rotation in 21 each week of control clutch pull rod cam arm of cam 20 control, the effect that becomes back and forth movement by circular movement all is the same, revolution move just can finish in a week clutch from, the overall process of closing.And by after complete all small gears 25 of the active of cam 20 coaxial rotation and 30 engagements of driven half cycle gearwheel, because the number of teeth of driven half cycle gearwheel 30 is one times of complete all small gear 25 numbers of teeth of active, so: when initiatively complete all small gears 25 rotated a week, driven half cycle gearwheel 30 just rotated half cycle.And the moving half cycle of driven half cycle gearwheel 30 revolutions will be finished the overall process by " bottom gear changes top gear into ", and the next half cycle that rotates can be finished, equally by the overall process of " top gear changes bottom gear into ".Can find out by the number of degrees frame bar signal of Fig. 3 cam 20, cam 20 rotates a week, the working procedure of clutch is: 0 ° → 15 ° sections are quick segregation section, 15 ° → 195 ° sections are thoroughly to separate and delay number, 195 ° → 270 ° are the gradual change adapter section, and 270 ° → 0 ° is complete adapter section.
