Figure 15 is the transparent view of motion transmission pawl 506.Motion transmission pawl 506 comprises the base portion 506a that has the hole 506b that is used to admit pawl axis 502, be used for contacting as follows the ratchet control surface 660 of intermediate plate 466 deceleration control surface 506c, positioning ratchet wheel drive surfaces 506d, unclamp plate drive surfaces 506e and mode converting pawl mating surfaces 506f and 506g.
Figure 16 (A)-(E) shows the working process of registration device 254 in acceleration direction.In Figure 16 (A), registration device 254 is in such position, and front chain shifter 70 is complementary with the preceding sprocket wheel of minor diameter and aims at, and wishes that front chain shifter 70 moves to the preceding sprocket wheel of middle diameter.In the position shown in Figure 16 (A), the top of drive controlling pawl 530 is by the upper surface 606a supporting of cam crown 606, the top of drive controlling pawl 538 is positioned at the bottom of the dip plane 610c of cam crown 610, thereby drive controlling pawl 538 contacts with binding face 578 on the motion transmission part 498, and motion transmission part 498 is remained on " cut-out " position.Therefore, drive controlling pawl 538 and cam crown 610 comprise the drive controlling mechanism that motion transmission part 498 can be remained on off-position usually.Motion transmission pawl 506 jack stays are on the upper surface of the driving gear 694 of positioning ratchet wheel 458.
Then, cyclist's conter clockwise (in Fig. 3) turns to actuation element 118 and quickens the position, thereby actuation element 118 unclamps inner cable wire 80.This just makes cable wire attaching parts 302 rotate along the clockwise direction among Fig. 6, and this moves through input connecting rod 306 and is delivered to control desk 518 and makes control desk 518 clockwise rotate the acceleration position shown in Figure 16 (B).The clockwise rotating of control desk 518 make drive controlling pawl 530 along the dip plane 606c of cam crown 606 to lower slider and rotate counterclockwise the position shown in Figure 16 (B).Simultaneously, drive controlling pawl 538 upwards slides along the dip plane 614b of cam crown 614, on binding face 578 and the upper surface 614a of jack stay in cam crown 614 on the drive controlling pawl 538 disengagement motion transmission parts 498.Because drive controlling pawl 538 no longer contacts binding face 578, therefore, motion transmission part 498 clockwise rotates up to drive controlling pawl 538 and contacts with binding face 588, and motion transmission part 498 is in " access " position shown in Figure 16 (B).Motion transmission pawl 506 is no longer kept by the driving gear on the positioning ratchet wheel 458 694, rotate counterclockwise and jack stay on the outer surface 678 of positioning ratchet wheel 458.Registration device connecting panel 402 and the back plate 406 of the cw Motion Transmission of motion transmission part 498 in the tumbler geared assembly 258, therefore, tumbler joggle piece 394 just turns to the position shown in Fig. 9 (B).
When turning to position shown in Fig. 9 (C) when the actuator on the crank 266 290 and 394 engagements of tumbler joggle piece and with registration device connecting panel 402 and back plate 406, motion just is delivered to motion transmission part 498.The positioning ratchet wheel drive surfaces 506d of motion transmission pawl 506 and 694 engagements of the driving gear on the positioning ratchet wheel 458 and rotational positioning ratchet 458 and tumbler 454 are reeled and are exported control cable wire 78.In this process, positioning teeth 682 presses the pawl teeth 475 of location ratchet 474 and clockwise rotates location ratchet 474, the top of crossing positioning teeth 682 up to pawl teeth 475.Then, location ratchet 474 rotates counterclockwise, thereby makes pawl teeth 475 between positioning teeth 682 and 686 shown in Figure 16 (C).
When the actuator on the crank 266 290 was thrown off tumbler joggle piece 394, registration device connecting panel 402 and back plate 406 were backward towards the rotated position shown in Fig. 9 (A), and this Motion Transmission is to motion transmission part 498.Motion transmission pawl 506 is thrown off the driving gear 694 on the positioning ratchet wheels 458, and positioning ratchet wheel 458 and tumbler 454 clockwise rotate under the partial pressure of spring 456, abuts on the pawl teeth 475 up to positioning teeth 682.At this moment, front chain shifter 70 on request with middle diameter before sprocket wheel be complementary and aim at.
But, suppose that this moment, the cyclist did not also rotate back into neutral gear position with actuation element 118.In the case, control desk 518 still is in and quickens the position, and drive controlling pawl 538 jack stays are on the upper surface 614a of cam crown 614.In this position, drive controlling pawl 538 can not contact the rotation of stop motion Transmission 498 with binding face 578.Therefore, replace and get back to the off-position shown in Figure 16 (A), motion transmission part 498 can be rotated further the on-position shown in Figure 16 (B), and tumbler joggle piece 394 can be got back to the tumbler engage position shown in Fig. 9 (B), and finishes another time speed change.This working process is desirable in some applications, and is positioned within the scope of the present invention.But, in this embodiment, drive controlling pawl 530 is set can avoids this dual speed change situation to take place.Specifically, by the drive controlling pawl 530 that has rotated counterclockwise as mentioned above be positioned at now with motion transmission part 498 on binding face 570 contacted positions on, and temporarily stop motion Transmission 498 further rotates, thereby motion transmission part 498 is on the position shown in Figure 16 (D).Therefore, drive controlling pawl 530 and cam crown 606 comprise drive controlling mechanism, this mechanism can forbid motion work will move be delivered to tumbler 454 from tumbler joggle piece 394 after motion transmission part 498 rotate back into the on-position.
When the cyclist turned back to neutral gear position with actuation element 118, control desk 518 rotated back into the neutral gear position shown in Figure 16 (E) similarly.At this moment, drive controlling pawl 530 upwards slides and clockwise rotates along the dip plane 606c of cam crown 606, up to the recline binding face 570 of motion transmission part 498 of control pawl 530, and the top jack stay of control pawl 530 is on the upper surface 606a of cam crown 606.And to lower slider and rotate counterclockwise, so the top of drive controlling pawl 538 contacts with the binding face 578 of motion transmission part 498 shown in Figure 16 (E) drive controlling pawl 538 along the dip plane 614b of cam crown 614.Motion transmission part 498 just is in the off-position of Figure 16 (A) shown in original now, but before the positioning ratchet wheel 458 of this position and tumbler 454 make front chain shifter 70 and middle diameter the sprocket wheel Matching Alignment.Therefrom sprocket wheel transforms to that the working process of sprocket wheel is identical before the major diameter before the diameter.
Figure 17 (A)-(F) shows the working process of registration device 254 in deceleration direction.For ease of understand the working process of the parts that play an important role in moderating process, some parts illustrates with the form of transparent view.Suppose that tumbler 454 is in such position, front chain shifter 70 and preceding sprocket wheel (the same position shown in Figure 16 (the E)) Matching Alignment of middle diameter, and wish to make front chain shifter 70 move to the minor diameter sprocket wheel.Therefore, in the position shown in Figure 17 (A), the top of drive controlling pawl 530 is supported by the upper surface 606a of cam crown 606 again, and the top of drive controlling pawl 538 is positioned at the bottom of the dip plane 610c of cam crown 610, like this, drive controlling pawl 538 just contacts with binding face 578 on the motion transmission part 498.Motion transmission pawl 506 jack stays are on the upper surface of the driving gear 698 of positioning ratchet wheel 458.Lobe plate 494 with elongated equicrural triangle global shape of rounding comprises extending axially locatees lug 495, and lug 495 abuts on the side 487 of unclamping plate 486, so that lobe plate 494 is remained on the position shown in Figure 17 (A).
Then, the cyclist turns to decelerate position with actuation element 118 cws (in Fig. 3), thereby spurs inner cable wire 80 by actuation element 118.This just makes cable wire attaching parts 302 along the anticlockwise motion among Fig. 6, and this move through the input connecting rod 306 be delivered to control desk 518, thereby control desk 518 is rotated counterclockwise shown in Figure 17 (B).Control desk 518 rotate counterclockwise make drive controlling pawl 530 along the dip plane 606b of cam crown 606 to lower slider and rotate counterclockwise.Simultaneously, drive controlling pawl 538 upwards slides and clockwise rotates along the dip plane 610c of cam crown 610, up to the binding face 578 of drive controlling pawl 538 and motion transmission part 498 recline and the upper surface 610a of jack stay in cam crown 610 on.Because drive controlling pawl 538 no longer contacts with binding face 578, motion transmission part 498 clockwise rotates, and contacts with binding face 588 and motion transmission part 498 is in the on-position shown in Figure 17 (B) up to drive controlling pawl 538.At this moment, motion transmission pawl 506 clockwise rotates by the transitional surface 618b of cam crown 618, and mode converting pawl 514 clockwise rotates with mode converting pawl mating surfaces 506f on the motion transmission pawl 506 and contacts, so that temporarily motion transmission pawl 506 is remained on the position shown in Figure 17 (B).Registration device connecting panel 402 and the back plate 406 of the Motion Transmission of motion transmission part 498 in the tumbler geared assembly 258, thus tumbler joggle piece 394 turns to the position shown in Fig. 9 (B).
When turning to position shown in Fig. 9 (C) when the actuator on the crank 266 290 and 394 engagements of tumbler joggle piece and with registration device connecting panel 402 and back plate 406, motion is delivered to motion transmission part 498 again, but the binding face 487 on this moment the unclamping plate drive surfaces 506e and unclamp plate 486 (being in the first unlocking element position at present) of motion transmission pawl 506 contacts, and unclamps plate 486 and rotate counterclockwise shown in Figure 17 (C).Therefore, motion transmission part 498 is used as the actuator that unclamps that unclamps plate 486 under this pattern.Rotate owing to unclamp plate 486, the basal plane 496 of lobe plate 494 contacts with being connected the cam roller 478 of locating ratchet 474, and location ratchet 474 is rotated along clockwise direction.When the top of positioning teeth 682 is crossed on the top of pawl teeth 475, positioning ratchet wheel 458 and tumbler 454 clockwise rotate under the partial pressure of spring 456, abut on the pawl teeth 476 to avoid positioning ratchet wheel 458 and tumbler 454 uncontrolled rotations up to positioning teeth 686.
Continue to the second unlocking element position (unclamping the end of plate 486 range of movement) when rotating counterclockwise when unclamping plate 486, cam roller 478 arrives the fillet or the cam crown 497 of lobe plate 494, thereby lobe plate 494 is rotated shown in Figure 17 (C) in the counterclockwise direction.This just makes location ratchet 474 rotate in the counterclockwise direction then, thereby pawl teeth 476 is left positioning teeth 686, and make positioning ratchet wheel 458 and tumbler 454 continue to rotate along clockwise direction, and in place up to tumbler 454, thus make front chain shifter 70 and minor diameter sprocket wheel Matching Alignment.
If this system carries out work like that according to the known system that adopts location ratchet and positioning ratchet wheel to control variable speed operation, pawl teeth 476 just still with positioning teeth 686 keep engagement up to unclamp plate 486 oppositely (just rotate along clockwise direction) thus finish variable speed operation.Because even when unclamping plate 486 and still rotate in the counterclockwise direction, rotating lobe plate 494 also allows location ratchet 474 to finish variable speed operation immediately, therefore, this for the variable speed control mechanism that the present invention constructs not necessarily.Therefore, unclamp plate 486 and lobe plate 494 and can be considered to a kind of control mechanism that unclamps, when unclamping plate 486 when move in the second unlocking element position, this mechanism makes location ratchet 474 move to the release position, position, continue when move in the second unlocking element position when unclamping plate 486, this mechanism allows location ratchet 474 to turn back to the holding position, position.
Even another advantage of preferred embodiment is to unclamp plate 486 to allow counter motion when the motion transmission part still rotates in the counterclockwise direction.According to preferred embodiment, when motion transmission part 498 was positioned at position shown in Figure 17 (C) and 18 (A), shown in Figure 18 (A), the deceleration control of motion transmission pawl 506 surface 506c began to contact with the ratchet control surface 660 of intermediate plate 466.Motion transmission part 498 further rotates motion transmission pawl 506 is rotated counterclockwise shown in Figure 17 (D) and 18 (B), motion transmission pawl 506 is thrown off unclamp plate 486.Mode converting pawl 514 is also thrown off the mode converting pawl mating surfaces 506f of motion transmission pawl 506, and jack stay is on mode converting pawl mating surfaces 506g.Therefore, even when motion transmission part 498 still is in conter clockwise position shown in Figure 17 (D), unclamps plate 486 and allow to turn back to immediately the position shown in Figure 17 (D).
When the actuator on the crank 266 290 was thrown off tumbler joggle piece 394, registration device connecting panel 402 and back plate 406 rotated back into the position shown in Fig. 9 (A) again, and this Motion Transmission is to motion transmission part 498.Again, suppose that the cyclist does not also rotate back into neutral gear position with actuation element 118.In the case, control desk 518 still is in decelerate position, drive controlling pawl 538 jack stays are on the upper surface 610a of cam crown 610, but drive controlling pawl 530 contacts with binding face 570 on the motion transmission part 498, thereby motion transmission part 498 is in the time-out position shown in Figure 17 (E).
When the cyclist turned back to neutral gear position with actuation element 118, control desk 518 cw similarly rotated back into the neutral gear position shown in Figure 17 (F).At this moment, drive controlling pawl 530 upwards slides and clockwise rotates along the dip plane 606b of cam crown 606, throws off up to drive controlling pawl 530 on the upper surface 606a of top jack stay in cam crown 606 of binding face 570 on the motion transmission parts 498 and drive controlling pawl 530.Simultaneously, drive controlling pawl 538 along the dip plane 610c of cam crown 610 to lower slider and rotate counterclockwise, thereby the top of drive controlling pawl 538 contacts with binding face 578 on the motion transmission part 498 shown in Figure 17 (F).Motion transmission part 498 is in the original off-position shown in Figure 17 (A) now, and still, positioning ratchet wheel 458 and tumbler 454 are in the position that makes front chain shifter 70 and the preceding sprocket wheel Matching Alignment of minor diameter.
Sprocket wheel is transformed into before major diameter before the diameter working process of sprocket wheel be same.But in the case, positioning ratchet wheel 458 initial alignments make pawl teeth 475 abut on the positioning teeth 686.When location ratchet 474 when clockwise rotating in response to the pressure of lobe plate 494, pawl teeth 475 is crossed positioning teeth 686, and positioning ratchet wheel 458 rotates counterclockwise, and contacts with pawl teeth 476 up to positioning teeth 690.When the cam crown 497 of lobe plate 494 arrives cam rollers 478 and when location ratchet 474 is rotated counterclockwise, pawl teeth 475 enters in the gap between positioning teeth 682 and 686, and pawl teeth 476 is unclamped positioning teeth 690, thereby positioning ratchet wheel 458 and tumbler 454 clockwise rotate, contact with pawl teeth 475 up to positioning teeth 682, thereby positioning ratchet wheel 458 and tumbler 454 are remained on the position shown in Figure 17 (A).
Although be provided with the drive controlling pawl 530 and 538 that carries out work separately in the above-described embodiments,, the embodiment shown in Figure 19 (A) and 19 (B) shows the single drive controlling pawl 700 with pawl teeth 704 and 708.When motion transmission part 498 was in initial position shown in Figure 19 (A), pawl teeth 704 contacted with binding face 578 on the motion transmission part 498.When motion transmission part 498 is just clockwise rotating off-position and control desk 486 when also not turning to neutral gear position shown in Figure 19 (B), pawl teeth 708 contacts with binding face 570 on the motion transmission part 498.
Although in first embodiment, adopt lobe plate 494 in the deceleration working process, to control location ratchet 474,, Figure 20 shows an embodiment who adopts cam 750 to control location ratchet 474 working processs.In this embodiment, cam 750 is coaxial and be rotatably mounted with respect to positioning ratchet wheel 458.Cam 750 comprises a plurality of cam tooth 754 and a plurality of cam drive teeth 758 along circumferential arrangement along circumferential arrangement.Cam drive pawl 762 is installed in rotation on by pivot 766 and unclamps on the plate 486 ', and carries out bias voltage in the counterclockwise direction by spring 770.When unclamping plate 486 ' and rotate in the counterclockwise direction in the deceleration working process, in cam drive pawl 762 and a plurality of cam drive teeth 758 one is meshed and rotating cam 750 in the counterclockwise direction.One in a plurality of cam tooth 754 is pressed against on the cam roller 478, and location ratchet 474 is rotated along clockwise direction in the mode identical with preferred embodiment.When cam tooth 754 strode across cam roller 478, location ratchet 474 rotated in the counterclockwise direction and finishes deceleration-operation.When unclamping plate 486 ' and rotate along clockwise direction, cam drive pawl 762 is thrown off with corresponding cam drive tooth 758.
