The power transfer operation
When speed change and locking, be to select to carry out variable speed operation by operating knob 21,22 simultaneously and make variable speed motor 29 work, sleeve 77 rotations carried out by operating body 78 by operation scale 23 modes of carrying out of variable speed operation portion 9.
Figure 12 is the diagram of circuit that shows the control operation of bright variable speed control portion 25.
Energized is carried out initial setting in step S1.Here all long datas of speed being calculated usefulness are set by 26 inch diameters, and speed change is set at two-speed (V2).
Whether be set at step S2 decision operation scale 23 and stopped flowing mode.Whether be set at the automatic speed changing mode at step S3 decision operation scale 23.Whether be set at the hand gear mode at step S4 decision operation scale 23.Judge whether to have selected the diameter of tyres input to wait other processing at step S5.
Be set to when stopping flowing mode when operating scale 23 to return the P position, transfer to step S10 from step S2.Carrying out operation scale P shown in Figure 13 at step S10 handles.Operation scale 23 is got back to behind the A position and when being set to the automatic speed changing mode, is transferred to step S11 from step S3.At step S11, carry out Figure 15 shown in automatic speed changing handle.When setting the hand gear mode, transfer to step S12 from step S4 when operating scale 23 to get back to the M position.At step S12, carry out hand gear shown in Figure 16 and handle.When selecting other to handle, then transfer to step S13 from step S5, select to handle.
In the operation scale P of step S1 handles, in Figure 13 step S21 judge whether passed through 30 seconds after forwarding the P position to.Judge whether not login password PW at step S22.Whether this judgement is to be stored in the storage part 30 according to password PW to judge.Logined already when password and promptly to have transferred to step 23.
At step S23, judged whether to start the operating knob 21 in left side.At this start-up function button the 21, the 22nd, remove the locking of blocked built in type speed-variating hub 10 in order to input password.At step S24, judged whether to start the operating knob 22 on right side.At step S25, judge whether the password LR that is imported by the operation of two operating knobs 21,22 of starting is consistent with the password PW that deposits.When inconsistent, transfer to step S26.At step S26, judge whether password is inconsistent under three inputs.Then be not back to step S23 carrying out three inputs, allow to input once more password.Even when three input passwords are not consistent with the password PW of login yet, transfer to step S27.At step S27, wait for 10 minutes, after 10 minutes, turn back to step S23, allow to input once more password.
Forward the P position to through after 30 seconds, be transferred to step S30 from step S21.At step S30, drive variable speed motor 29 by motor driver 28, control position VP is set to latched position PK.As a result, sleeve 77 rotates by operating body 78, shown in Fig. 7 and 8, driving claw 71 actions, lock pawl 92 moves to the direct of travel locking with 41 of first sun wheel 60 and hub spindles, and 41 of the 3rd sun wheel 62 and hub spindles are locked it on the direction opposite with direct of travel can not rotate.After having locked two sun wheels 60,62 in this wise, after making crank gear 18 rotations and allowing driving body 42 rotate,, carry out maximum speedup because first sun wheel is locked at direct of travel.But because the 3rd sun wheel 62 can not reverse, sun and planet gear 44 is locked motionless.Therefore stepping step tread plate can not move, because bicycle becomes and can not utilize, is difficult to become the theft object.
This moment is if use the hand propelled bicycle, though then locked sun and planet gear 44, but by means of free-wheel clutch 80, bicycle advances.But when sleeve 77 turns to latched position PK, the joint fastener 105 of the spring washer 101 that rotates simultaneously with sleeve 77 is just pushed by the cam body 106 of pronunciation mechanism 100, from position shown in Fig. 9 and Figure 11 (A) to position axis shown in Figure 10 and Figure 11 (B), (C) to moving to left.So the ratchet 111 that goes out sound packing ring 103 is limited to hub shell 43 with 112 engagements of the hook tooth of hub shell 43 becomes unitary rotation on direct of travel.At this moment, the tablet 112 that goes out that goes out sound packing ring 103 is come in and gone out in the big conflict sound equipment in the sound ditch 109 of going out that goes out sound cam 102.So, when lock-out state, just send very big sound equipment when being used to promote bicycle, further stoped robber's car incident to take place.
When password PW does not login, transfer to step S31 from step S22.At step S31, carry out password login process shown in Figure 14.At this, whether started by the step S41 decision operation 21 of Figure 14.If operating knob 21 has started, then transfer step S42 adds 1 with left sequence number L (10 sequence numbers).At step S43, whether decision operation button 22 is started.Operating knob 22 is returned step 41 before pushing, make left sequence number L respectively add 1.During start-up function button 22, transfer to step S44, make right sequence number L respectively add 1.During start-up function button 22, transfer to step S44, make right sequence number R (individual position sequence number) add 1.At step S45, whether decision operation button 21 is started once again.Before operating knob 21 is by starting, return step S43, make right sequence number R add 1 at every turn.During start-up function button 21, transfer to step S46, the sequence number LR that imports is stored in the storage part 30 as password PW.Like this, the password PW one of from 2 100 sequence number LR of [00]～[99] is logged.
At step S23, step S32 is promptly transferred in operating knob 21 startings when judgement unlocks.At step S32, identical when logining with password, make left sequence number add 1 at every turn.When 22 startings of decision operation button.Promptly transfer to step S32 from step S24.In step S32, identical when logining with password, make right sequence number R respectively add 1.At step S25, when the sequence number LR of input is consistent with password PW, then transfer to step S34, control position VP is transferred to a fast V1.Be positioned a fast V1 so by variable speed motor 29 sleeve 77 is rotated, the lock pawl 92 of the 3rd sun wheel 62 is thrown off, and all driving claw 71-73 throw off simultaneously.Like this, all sun wheel 60-62 are free to rotate with respect to hub spindle 41.As a result, pedal plate when stepping, the rotation of driving body 42 just passes to hub shell 43 by first free-wheel clutch 80 to former state.
Automatic speed changing at step S11 is handled, and control position VP is set to the corresponding speed change level with speed of a motor vehicle SP.Then, in other occasion.Towards approaching direction speed change step by step.Here, in the step S51 of Figure 15, the speed of a motor vehicle SP that judges bicycle according to the speed signal of car speed sensor 12 at step S52, judges whether outpace S1 and below S2 of speed of a motor vehicle SP whether below speed S1.At step S53, judge whether speed of a motor vehicle SP outpaces S2 below S3.At step S54, judge whether speed of a motor vehicle SP surpasses S3.
When the low speed situation of speed of a motor vehicle SP below speed S1, promptly by step S51 transfer step S55.At step S55, judge whether present control position VP is a fast VI.When control position VP is not a fast VI, then transfer to step S56, adjust the speed change level step by step, make control position VP become a fast VI.As outpace S1 but middle low speed situation below speed S2 is promptly transferred to step S57 from step S52 of speed of a motor vehicle SP.At step S57, judge whether control position VP now is two-speed V2.When control position VP is not two-speed V2, promptly be transferred to step S58, carry out the adjustment of speed change level step by step, make control position VP become two-speed V2.As outpace S2 but high speed situation below speed S3 is promptly transferred to step S59 from step S53 of the speed of a motor vehicle.At step S59, judge whether present control position VP is three fast V3.When control position VP is not three fast V3, promptly transfer to the adjustment that step S60 carries out the speed change level step by step, control position VP is adjusted to three fast V3.When speed of a motor vehicle SP in the high speed situations of S3 that outpaces, just transfer to step 61 from step S54.At step S61, judge whether present control position VP is four fast V4.When control position VP is not four fast V4, transfer to step S62 and carry out the adjustment of speed change level step by step, make control position VP become speed V4.
At this, by variable speed motor 29, when being connected with hub spindle 41, first sun wheel 60 becomes four fast V4, be input to the rotation of driving body 42 from sprocket wheel 47, the determined maximum over-speed gear ratio speedup of the number of teeth according to by the first gear 63a, the second gear 63b and the gear ring 64 of first sun wheel 60, planetary wheel 63 is sent to hub shell 43 via second free-wheel clutch 81.When selecting second sun wheel 61 to connect with hub spindle 41, become three fast V3, and the rotation of driving body 42 is according to by second sun wheel 61, the determined second largest moderate over-speed gear ratio speedup of the second gear 63b of planetary wheel 63 and the number of teeth of gear ring 64 sends hub shell 43 to via second free-wheel clutch 81.When selecting the 3rd sun wheel 62 to be connected with hub spindle 41, become two-speed V2, and the rotation of driving body 42 sends hub shell 43 promptly according to the 3rd gear 63c, the second gear 63b of the 3rd sun wheel 61, planetary wheel 63 and the determined minimum over-speed gear ratio speedup of the number of teeth of gear ring mechanism 64 to via second free-wheel clutch 81.In addition, when not selecting arbitrary sun wheel 20-22, then as previously mentioned, become a fast V1, and the rotation of driving body 42 directly sends hub shell 43 to.
Non-selected sun wheel then relatively rotates in contrast to the direction of advancing with respect to hub spindle 41 edges.When arbitrary sun wheel is selected fixed and when carrying out speedup by sun and planet gear 44, driving body 42 and hub shell 43 are promptly removed the direction that engages with respect to first free-wheel clutch 80 and relatively rotated.
In the hand gear of step S11 is handled, be to carry out speed change step by step by the operation of operating knob 21,22.At the step S71 of Figure 16, whether decision operation button 21 is started.At step S72, whether decision operation button 22 is started.When operating knob 21 startings, promptly transfer to step S73 from step S71.At step S73, judge whether present control position VP is four fast V4.As present control position VP during at four fast V4, transfer to step S74, do not keep to speed change four fast V4.When present control position VP is not four fast V4, transfer to step S75, control position VP is done once to the transfer of level side at a high speed.When operating knob 22 startings, promptly transfer to step S73 by step S71.At step S73, judge whether present control position VP is a fast V1.As present control position VP during at a fast V1, transfer to step S77, do not keep to speed change speed V1.If present control position VP is not a fast V1, then transfer to step S78, control position VP is done once transfer to the low speed turbine stage side.In addition, under above-mentioned various situations, each position data of each control position compares in the storage part 30 with being pre-stored in the result that detects of control position sensor 26, and the location of variable speed motor 29 is controlled.
Form of implementation 2
In aforementioned form of implementation, in being provided with lockout mechanism 90 between sun wheel 62 and the hub spindle 41 in relative rotation, meanwhile, between hub spindle 41 and hub shell 43, be provided with pronunciation mechanism 100 in addition, in order to prevent to steal car, but also can between hub spindle 41 and hub shell 43, promptly travel between the parts in relative rotation, the anti-joyride device 85 with function of pronunciation and lock function is being set.
As shown in figure 17, built in type speed-variating hub 10a is installed with except that the anti-joyride device 85 that has lock function the pronunciation mechanism 100 of Fig. 4 in addition.So lock pawl is not set in sun wheel 62.Except that anti-joyride device 85, identical in other structure and operation and the aforementioned form of implementation 1 omitted its explanation.
Moving-member 103a has discoideus flange part 115 and integrally formed cylindrical portion 116 on flange part 115 circumference.In flange 115 in radially be formed with stage portion 115a midway, on stage portion 115a, supporting locking ring 114 free to rotately.In addition, on the face relative of the face relative of flange part 115 and locking ring 114, as shown in figure 21, be formed with radial jog 114a (only show and understand locking ring 114 1 sides) respectively with locking ring 114 with flange part 115.Owing to formed such jog 114a, made locking ring 114 and the friction force of moving-member 103a increase, so when they relatively rotate, promptly pronounce because of vibration.
At this, the crimp force of the amount of the being screwed into scalable disc spring 119 by the adjusting lock nut can be regulated the friction force between the flange part 115 of locking ring 114 and moving-member 103a, so can at random retrain the rotation of hub shell 43 via thrust ring 117.For example.When utilizing disc spring 119 to make above-mentioned friction force reach maximum, then hub shell 43 just becomes the lock-out state that can not rotate substantially.When friction force was reduced, the power that constraint hub shell 43 is rotated just weakened, so hub shell 43 just can be rotated with respect to hub spindle 41.Even but under such situation, disc spring 119 also is under the afterburning state and produces friction force, compares with free rotary state, make to rotate to suffer restraints.In this form of implementation, can retrain freely by the elastic force of regulating disc spring 119, making wheel hub 43 is the rotation of trailing wheel 7, can change near the state that freely rotates from lock-out state in fact.
In the periphery of locking ring 114, as shown in figure 21, be formed with serration 114b.Serration 114b can with the serration 113a engagement that forms on hub shell 43 inner peripheral surfaces.
In the anti-joyride device 85 of getting said structure, when sleeve 77 turns to latched position PK from shift position, the joint fastener 105 of the spring washer 101 that rotates simultaneously with sleeve 77 is convenient to move in the cam part 108a.When joint fastener 105 moves in cam part 108a, be moved power-assisted moving-member 103a of spring 104a and translating cam 102a just from position shown in Figure 18 and Figure 20 (A), move to right to position shown in Figure 19 and Figure 20 (B).So, the serration 114b of locking ring 114 just meshes with the serration 113a of hub shell 43, locked ring 114 of the rotation of hub shell 43 and the friction force of moving-member 103a are retrained, and friction force at this moment can be able to any change by the elastic force that the amount of being screwed into of jam nut 118 is regulated disc spring 119.Like this, pedal plate even step, trailing wheel 7 yet can not rotate or be difficult to rotate.
At this moment, if rotate hub shell 43 by force, moving-member 103a and locking ring 114 just relatively rotate, because jog 114a is arranged, locking ring 114 just because of vibration very big rattle takes place with moving-member 103a.Like this, when lock-out state, be used to promote self-moving vehicle or step step tread plate when rotating hub shell 43, will send the big sound and make and steal car and be difficult to.But under steam because maloperation makes sleeve 77 misplaces when latched position, though can trailing wheel 7 be locked hastily because of the rotation of frictional constraint trailing wheel 7.
In addition, in aforementioned form of implementation 1.Owing to be the locking sun wheel, when sleeve 77 is in latched position, can not ride bicycle though step on pedal, can promote bicycle.In this form of implementation 2, owing to be hub shell 43 to be directly connected on the hub spindle 41 lock, even remove to promote bicycle, but the rotation of hub shell 43 (trailing wheel 7) suffers restraints, and promotes also very difficultly, wants car is stolen just more difficult.
Form of implementation 3
In front in two kinds of forms of implementation, be that the built in type speed-variating hub 10 with trailing wheel 7 usefulness is that example describes, but also can anti-joyride device 85 be located in the front wheel hub 120 of front-wheel 6 usefulness as shown in figure 22.
In this form of implementation 3, for example can be with among being located at handlebar grip 15 at the lock operation bar of swinging between latched position and latch-release position.Like this, can on the lock operation bar, lock, and during, when lock not being untied, also can not recover by input password sequence number or with key insertion etc. from latched position to the latch-release position.Also can allow above-mentioned lock operation bar and securing rod 121 be connected, by lock operation bar 121 sleeve 77a be rotated, and moving-member is moved between latched position and latch-release position by hawser.
Form of implementation 4
All be anti-joyride device to be located among the wheel hub of wheel in aforementioned three kinds of forms of implementation, but also can anti-joyride device 85a be located in the built in type speed change crank 130 of drive division 5 as shown in figure 23.
Built in type speed change crank 130 can carry out height two-stage speed change and lock operation.This built in type speed change crank 130 comprises: axis 132, and it has the crank shaft 131 among the cradle portion 2a that is installed in cycle frame body 2; About crank arm 133a, 133b; Sun and planet gear 134; The crank gear 135 that is connected with planetary wheel 134; And be located at anti-joyride device 85a in the sun and planet gear 134.
Crank shaft 31 is supported in the barrel-contoured axis 132 free to rotately.At its two ends, crank arm 133a and 133b are mounted to and can not be rotated by hold-down bolt 140.Axis 132 has the tubular support body 141 of supporting crank shaft 131, on the right-hand member of support body 141 integrally formed case portion 142, set mounting screw 143 at support body 141 left ends.Axis 132, by screw 143 is installed that the support body 141 that inserts in the cradle portion 2a is fixing securely, and be installed among the cradle portion 2a, simultaneously by the radius arm 144 that is installed on case portion 142, vehicle frame 2 is held in can not rotate.
Sun and planet gear 134 as shown in figure 24, have the gear ring 145 that is formed on the 142b of the portion inner peripheral surface, with three planetary wheels 146 of gear ring 145 ingears (one of them only is shown among Figure 24), with planetary wheel 146 ingear sun wheels 147.
The 142b's of tube portion is installed with the conversion plectane 151 that can not rotate but can move freely vertically interior week in case portion 142.Conversion plectane 151 can move vertically by the swing of conversion rod 152.In addition, conversion plectane 151 can by because of in do not show the left effect of bright acting device in Figure 24.But conversion rod 152 free swaying ground supportings have formed oblique cam (not shown in the figures bright) on conversion plectane 151 joins the side therewith in case portion 142, by swing, conversion plectane 151 is moved vertically, and in the upper end operation hawser is installed.This operation hawser is installed on the bright shifter bar not shown in the figures.This shifter bar for example has high speed, low speed and locking totally three positions, can lock to remain on this position in latched position.
Be formed with on the right flank of conversion plectane 151 can with the stop ditch 148a ingear stop ditch 151a radially that forms on the framework 148.Constituted anti-joyride device 85a by this stop ditch 148a, 151a and conversion plectane 151.Interior all right-hand members of conversion plectane 151 then form the conversion pawl 151b that can be used to make the driving claw swing but can not drive it is arranged.The 151c of tooth portion that the engagement tube 142b of portion is arranged in the outer circumferential side form of conversion plectane 151 then.
Get the built in type speed change crank 130 of said structure, when shifter bar was swung to high speed position, just conversion rod 152 is swung by the speed change hawser, shown in Figure 24 (A), this conversion plectane 151 was disposed at the high speed position in left side.Under this state, framework 148 is connected by driving claw 155 with crank shaft 131.As a result, crank shaft 131 just directly sends framework 148 in the rotation of direct of travel, and crank gear 135 is with the rotational speed identical with crank shaft 131.
When shifter bar was rocked to low-speed position, conversion rod 152 was promptly swung through the speed change hawser, and shown in Figure 24 (B), conversion plectane 151 promptly is disposed at the low-speed position of central authorities.Under this state, driving claw 155 is swung by the conversion pawl 151b of conversion plectane 151, and driving claw 155 becomes and can not drive.As a result, framework 148 was freed with being connected of crank 131.So crank shaft 131 follows into that the rotation of direction just sends sun wheel 147 to by driving claw 149.Rotate when sun wheel 147 follows into direction, the just reverse rotation of planetary wheel 146 follows into the direction revolution of slowing down simultaneously.Like this, crank gear 135 just rotates via framework 148 decelerations.
When shifter bar swung to latched position, this state can lead to the input password or add maintenance such as latching operation.When shifter bar is placed this latched position, just conversion rod 152 passes through the swing of speed change hawser, shown in Figure 24 (C), 151 latched positions that are located at the right side of conversion plectane.Under this state, the conversion pawl 151b swing of driving claw 155 by conversion plectane 151, driving claw 155 becomes and can not drive.Simultaneously, 148 engagements of stop ditch 151a and stop ditch, framework 148 is connected with case portion 142 by conversion plectane 151 and locked.So even allow crank arm 133a, 133b follow into direction rotation, but crank shaft 131 is locked, crank gear 135 does not rotate.But when crank arm 133a, 133b rotate along direction of retreat, though framework 148 lockings, but driving claw 149 is separated from sun wheel 147.So crank shaft 131 can rotate.But the rotation of crank shaft 131 does not send crank gear to.So in this state, pedal plate bicycle is walked about, thereby bicycle is difficult for being stolen even step.
Have again,,, conversion plectane and framework 148 are relatively rotated then in latched position when giving the effect of conversion plectane with suitable acting device from Figure 24 left side.At this moment rotation suffers restraints, and can be owing to relatively rotating.
Other form of implementation
(a) in above-mentioned four kinds of forms of implementation, anti-joyride device is only to form with pronunciation mechanism by lockout mechanism or by lockout mechanism, but also can only constitute anti-joyride device by pronunciation mechanism.
(b) select the structure of clutch mechanism to be not limited to above-mentioned form of implementation, but all distortion can be arranged.
(c) even if the structure of sun and planet gear can have various forms too.For example can constitute planetary gear construction, and between two planetary gear units, the roll shape free-wheel clutch can be set by about two and the planetary gear unit established.In addition, then can be identical in above-mentioned each planetary gear unit with aforementioned form of implementation, constitute by sun wheel, planetary wheel and gear ring.
(d) be the sun and planet gear that the present invention is used for secondary or level Four speed change in above-mentioned each form of implementation, but the present invention is not limited to this, also can be used in built-in speed varying unit three-step gear shift or that the Pyatyi speed change is above.
(e) in aforementioned each form of implementation, be by sleeve 77 as a kind of equipment lock, pronunciation and speed change, but the present invention is not limited by this, but can realize locking, pronunciation and speed change respectively with other different operating device, can also lock respectively and pronounce by the different operating device.
(f) in aforementioned each form of implementation, be to constitute by driving claw 71 and lock pawl 92 to make sun and planet gear 44 out-of-run structures, power can not be transmitted, but the present invention is not limited to this.For example, promptly enable to transmit power, also can make power not send hub shell 43 to by idle running by driving body 42.
Also desirable in addition such structure, when lock pawl 92 join to firmly with hub spindle 41 in conjunction with on the projection 41a and the face that lock pawl 92 engages the time, for making latch-release form the conical surface, like this, lock pawl 92 just can repeat intermittently with the locking and the latch-release of hub spindle 41.At this moment under parking mode, when setting foot on step tread plate, bicycle can be walked about off and on, but it is then difficult normally to walk about.This structure is also included among the present invention.
For anti-joyride device of the present invention, do not ride situation when placing at bicycle, pronunciation device and/or rotational restraint device are adjusted to can pronunciation state and/or during the rotational restraint state, when the people who does not know these ins and outs when stealing will the riding away bicycle of purpose, this anti-joyride device just pronounces and/or retrains rotation, when bicycle is moved by force, will pronounce and/or limit rotation, be difficult to walking.Therefore, other people ride away bicycle is difficult, and can also report simultaneously the third party has beyond the car owner other people just riding away bicycle.So car is ridden away steathily just more difficult, thereby can reduce the car robbery accident as far as possible.
Built-in speed varying unit according to the present invention is to send driving body to from the power of input body, sends driven member to from driving body again.At this moment, after equipment made transmission system action, sun and planet gear one of just transformed in its many power transmission paths and to carry out speed change.On the other hand, when equipment makes blocking device carry out lock out action, even then dynamic from the input body send driving body to, this power can not send driven member to yet.Therefore, although for example step step tread plate, can not drive wheels.So, just at last car is stolen, can not make bicycle running but when riding, stepped step tread plate, thereby this bicycle of stealing can't utilize, this has just reduced the possibility of the bicycle theft that is provided with built-in speed varying unit to greatest extent.
