Rear chiain-moving device 42 mainly comprises following various parts: a base member 50; A movable link 51; A chain guides 52; 53, one in a linkage assembly is gone up angle sheave 54 and a following stretching pulley 55.Rear chiain-moving device 42 also comprises a sense of rotation testing agency 60 that is installed between above-mentioned chain guides 52 and the following stretching pulley 55.Certainly, those skilled in the art can be very clear from above disclosure, and above-mentioned sense of rotation testing agency 60 also can be installed between chain guides 52 and the last angle sheave 54 as following second embodiment is described.
The rotation of the sense of rotation testing agency 60 following stretching pulley 55 by detecting rear chiain-moving device 42 detects the march forward rotation of direction of motion of crank 35 and 36.There is a rotation sensor 29 that is fixed on the above-mentioned chain guides 52 in sense of rotation testing agency 60; One is installed in down and makes it can be rotated sensor 29 detected detecting elements 61 on the stretching pulley 55; And a guard mechanism 62, this guard mechanism makes rotation sensor 29 only march forward travel direction when rotation at crank 35 and 36, could output signal.Rotation sensor 29 is a reed switch normally, and it relies on the magnetic force of detecting element 61 generations, alternately is in the state of " leading to " and " breaking ".Above-mentioned detecting element 61 has the magnet on the periphery that is fixed on above-mentioned down stretching pulley 55.When detecting element 61 during by the position relative with above-mentioned rotation sensor 29, rotation sensor 29 is just exported a pulse.
Coupling compoonent 66 designs and makes and makes that blocking arm 65 rotates to first direction A (with the opposite direction of crank forward direction rotation) and second direction B (direction of crank forward direction rotation) in contrast with the rotation of wheel 55.Locator protrusions 67 then designs and makes and makes the arm 65 that blocks that is driven by coupling compoonent 66 be positioned at and block on the position or on the detection position.
Coupling compoonent 66 is installed in down stretching pulley 55 and blocks between the arm 65, it is contacted with both, and can couple together both by means of friction force.Therefore, be positioned projection 67 when stopping on certain position when blocking arm 65, coupling compoonent 66 just abuts against to block on the arm 65 and slides.Like this, only connect with following stretching pulley 55, so when stretching pulley 55 rotates down by friction force owing to block arm 65, if blocking arm 65 stops on the certain location, so, even stretching pulley 55 continues rotation down, block arm 65 and also can stop on this position.
In rotation direction detecting devices 60 with said structure, for example, when as the step (a) of Fig. 7 with (b), step 32a and 32b are scrunched towards the direction opposite with forward travel, and when following stretching pulley 55 rotates to the first sense of rotation A, because the effect of coupling compoonent 66 is blocked arm 65 and also rotated towards this direction, be positioned at blocking on the position shown in the step (c) of Fig. 7 so block arm 65 projection 67 that just is positioned.This blocks the position is position towards rotation sensor 29.When blocking arm 65 and be in this and block the position and since coupling compoonent 66 only frictionally and following stretching pulley 55 with block arm 65 and be bound up, so even blocking arm 65 stops on this position, following stretching pulley 55 still can be rotated further.Like this, even being installed in down detecting element 61 on the stretching pulley 55 turns to relative with rotation sensor 29 locational the time, because blocking arm 65 is between detecting element 61 and the rotation sensor 29, rotation sensor 29 can not detect the magnetic force of detecting element 61, thereby rotation sensor 29 can be to shift controller 15 output electric pulses.
On the other hand, shown in the step among Fig. 7 (e), (f), when step 32a, 32b are scrunched towards the direction of bicycle forward travel, make that stretching pulley 55 is when the second sense of rotation B rotates down, because the effect of coupling compoonent 66, block arm 65 and also rotate, so block arm 65 just owing to locator protrusions 67 is positioned on the detection position shown in the step (g) among Fig. 7 to same direction.This detection position is not relative with rotation sensor 29 position.At this moment and since coupling compoonent 66 be only frictionally with following stretching pulley 55 with block arm 65 connections, so, stop on the detection position even block arm 65, following stretching pulley 55 still is rotated further.When the detecting element 61 on being installed in down stretching pulley 55 turns on the position of rotation sensor 29, because blocking arm 65 is not between detecting element 61 and the rotation sensor 29, so rotation sensor 29 just can detect the magnetic force that detecting element 61 sends, and to shift controller 15 output electric pulses.As a result, according to the pulse of being exported, just can detect crank 35 and 36 and whether rotate towards the direction of bicycle forward travel from the rotation sensor 29 of rotation direction detecting devices 60.
Use an independent rotation sensor 29 owing to have 60 of the rotation direction detecting devices of this formation, just can detect crank 35,36 and whether rotate, thereby can realize simple and compact structure towards the direction of bicycle forward travel.In addition, owing to only need to handle from an independent signal that rotation sensor 29 is launched, so can detect the sense of rotation of crank 35 and 36 with very simple processing mode.
Action
Below, be example with a kind of gear-shifting control method of shift controller 15, with reference to the control flow chart shown in Fig. 8, the gear-shifting control method that the outside shifter 9 in rear is implemented is described.Because the gear-shifting control method that the outside shifter 8 in the place ahead is implemented, except the shelves that change were fewer, all the gear-shifting control method with the outside shifter 9 in rear was identical for other, so just omitted the explanation to it here.
The bicyclist is led to the power switch 25 of shift controller 15, just can carry out gear shift to bicycle 1 and control.After power switch 25 was connected, at first, in step S1, shift controller 15 carried out initialization.Meanwhile, the data that is stored in the storer 22 is carried out initialization.For example, current shelves SH is set at second grade.
In step S2, obtain current gear from the shift pattern sensor of rear chiain-moving device 42, and this gear is stored in the storer 22 as the SH value.The SH value is in order to store the count value that current gear value is used, for example, when current gear is one grade, be " 1 " corresponding to the numerical value of this gear, and the numerical value of current gear when being third gear is " 3 " or the like, and will store with the corresponding numerical value of these gears.After having stored the SH value, the CPU21 of shift controller 15 just transfers to step S3.
In step S3, the order whether decision sends gear up.When manual shift mode, this decision is made after having exported the gear up shift signal having determined whether to have pushed the rear portion gear up button 18a of gear-change operation parts 14a.When automatic shift mode, this decision is to determine the speed of a motor vehicle is made after whether having surpassed threshold value with the corresponding gear up of each gear.In step S4, determine whether to send the order of gear down.When manual shift mode, this decision has been exported the shift signal of gear down and has been made having determined whether to have pushed the rear portion gear down button 19a of gear-change operation parts 14a.When automatic shift mode, this decision is to determine the speed of a motor vehicle is made after whether being lower than threshold value with the corresponding gear down of each gear.In step S5, determine whether to send the order that requires to carry out other processing, for example, require to show, and require to carry out various settings or the like.
When sending the order of gear up in step S3, CPU21 just transfers to step S6 with step from step S3, according to the pulse of being sent from rotation sensor 29, determines whether crank 35 and 36 rotates towards the direction of bicycle forward travel.If crank 35 and 36 towards the direction of forward travel (promptly, towards second direction B) when rotating, rotation sensor 29 is just according to such transponder pulse described above, otherwise, that is,, perhaps stop operating if crank 35 and 36 rotates to first direction A, just according to described above, transponder pulse not.
For gear shift, outside shifter 8 and 9 will be transferred to chain 7 on another sprocket wheel from a sprocket wheel, if chain 7 does not rotate, and does not have the tension force effect on chain 7, just can not carry out the gear shift action.Therefore, in step S6, travel direction does not scrunch step 32a and 32b if the bicyclist does not march forward, and the gear shift action just can not be finished.If the decision in step S6 is a "No", with regard to not carrying out the gear shift action, just CPU21 gets back to step S4.If determining crank 35 and 36 in step S6 is to rotate towards the direction of forward travel, then CPU21 advances to step S7.In step S7, send the signal of gear up to connector 28 from CPU 21.Connector 28 is according to the gear up signal, to rear chiain-moving device 42 output drive signals.So rear chiain-moving device 42 is just changed to the higher shelves of next speed to gear.
Change to low-grade order if in step S4, send, just then CPU21 advances to step S8 from step S4, and the same,, determine the crank 35 and 36 travel direction rotation of whether marching forward according to the pulse that rotation sensor 29 is sent with step S6.If decision is "No" in step S8, with regard to not carrying out the gear shift action, so CPU21 just gets back to step S5.If crank 35 and 36 just rotates towards the direction of forward travel in step S8, then CPU21 advances to step S9.In step S9, export the gear down signals to connector 28 from CPU21.Connector 28 is according to the gear down signal, to rear chiain-moving device 42 output drive signals.So rear chiain-moving device 42 is just changed to next low or first gear to the speed of a motor vehicle.
When sending the order of carrying out other processing, CPU21 just advances to step S10 from step S5, carry out require other processing of carrying out.
In the present embodiment, make rotation sensor 29 be in the state that can not detect owing to blocking arm 65 by means of use, only just can detect crank 35 and 36 and rotate, so just can the simple and compact pick-up unit 60 of implementation structure in the travel direction of marching forward with an independent rotation sensor 29.In addition, because as long as processing is just passable from the signal that an independent rotation sensor 29 is sent, thereby need only very simple processing, just can detect the sense of rotation of crank 35 and 36.
In addition, owing to used non-contacting sensor in the present invention, that is, used cheap small-sized magnetically-actuated reed switch, so can further reduce the cost of device.
