Therefore, gear frame 33 is the shapes that form about ring-type, has the space of supporting that three planetary wheels 31 are used, become rotatably set hub spindle 10 around.In the periphery of three planetary wheels 31, be equipped with the 1st annular gear wheel 40.The outermost side face of the 1st annular gear wheel 40 is formed with croze 41.Croze 41 is to be engaged in the croze hole 42 that is fixed in the ring-type of shell 18 with bolt 43.As a result, the 1st annular gear wheel 40 is to be fixed in shell 18, and can't be fixedly linked on hub spindle 10 with the relative rotation.
The other end at the wheel hub 10 that approaches hub body 36 is formed with plane of rotation 45.At plane of rotation 45, rotating has steel ball 46.Invar ball 46 is the planes of rotation 48 that also rotate simultaneously in pushing spin 47, the result, and these are to become the formation bearing.Be integrally formed with two pieces of neck ring portions 48 abreast at hub body 36.Neck ring portion 48 is that an end of spoke (not giving diagram) firmly is fixed in spoke hole 49.
As a result, steel ball 35,46th, formation is propped up hub body 36 rotations freely and is held in hub spindle 10.Planetary wheel 31 is the 1st interior all teeth 44 that are engaged in the ring-type internal-gear that is formed on the 1st annular gear wheel 40.Dispose three the 2nd miniature gearss 41 at the 1st annular gear wheel 40.The axle 52 of the 2nd miniature gears 51 is to be supported at the 1st annular gear wheel 40, supports to have the 2nd miniature gears 51 freely in axle 52 rotations.
The 2nd miniature gears 51 is to be engaged on the outer peripheral teeth 53 of being located at gear frame 33.Side by side, the 2nd miniature gears 51 is the 2nd interior all teeth 54 that are engaged on the 2nd annular gear wheel 55.Cause the 2nd miniature gears 51 is not revolve round the sun, so the revolution of mat inner gear frame 33, becomes by outer peripheral teeth 53 to impose the rotation driving.Rotation by the 2nd miniature gears 51 is driven in rotation via the 2nd interior all tooth 54, the 2 annular gear wheels 55.
Represent that at the 3rd figure it is detailed, in the periphery of the 2nd annular gear wheel 55, be equipped with free-wheel clutch 60, that is be equipped with ratchet device.Nibble the quiet detailed cross sectional view of He what the 4th figure represented free-wheel clutch.The pawl 61 of free-wheel clutch 60 is the hook tooths 62 that are engaged in the inner peripheral surface that is formed on hub body 36.
Pawl 61 is to be formed with spring stop section 64.64 fasten circular spring 63 are arranged in this spring stop section, from outer circumferential center position with elastic force locking jaw 63.Mat should locking, because of pawl 61 is to become often to play the direction accumulation of heat to heavily fortified point and suppress, therefore becomes to be engaged in hook tooth 62.Pawl 61 is to prepare to add up to two kind persons.Another kind is any different persons (with reference to the 3rd figure) that spring stop section 64 is equipped on the opposition side of pawl 61.
The pawl 61 of another kind is to be configured every the work angle.Spend angles with the pawl 61 of this two kind every work 180, be equipped with two pawls of the same race 61 in the same phase place of same direction.As a result, be equipped with the pawl 61 of 4 of totals.Even to be the pass for the power of transmission electro-motor 15 be and increase the situation that driving torque does not have undercapacity yet for this.
Because of free-wheel clutch 60 is functions of the unidirectional rotational force of only transmission, that is one-way clutch mechanism, therefore, only can be with the transmission of power of electro-motor 15 to wheel.If when not possessing free-wheel clutch 60, when then stopping electro-motor 15 then the armature 19 of electro-motor 15 also become and drive moving and pedal can become heavy.Again, have, can interdict the advantage of the moment of inertia of armature 19 at glancing impact.
Above-mentioned free-wheel clutch 60 is to carry out stopping or removing of action.Possesses power-transfer clutch 70 again at this example.The pawl 71 of power-transfer clutch 70 is to be disposed at the 2nd annular gear wheel 55 every work 180 degree arranged spaced cracking for 72 (with reference to the 3rd figure) in two places.Be formed with axis hole 75 at pawl 71.Being inserted with pawl pin 74 at axis hole 75 is to be inserted in the 2nd annular gear wheel 55 formed pawl pin holes 75.
Pawl pin 74 be by circular pawl pin fixedly bullet build 76 and fixed and can't deviate from (with reference to the 1st figure) from pawl pin hole 75.Pawl 71 is to suppress with coil spring 77 accumulation of heats, often is engaged in the hook tooth 62 of the inner peripheral surface that is formed on hub body 36.On the one hand, at the croze axle 86 of hub spindle 10, there is power-transfer clutch releasing cam 80 to move and is located at axis direction freely.It is to suppress axis direction to wheel hub 1 by coil spring 81 frequent accumulation of heats that power-transfer clutch is removed cam 80.
Shown in the 6th figure, the side of removing cam 80 at power-transfer clutch is formed with angle θ, is formed with the angle position of pawl contact surface 82 in about angle 40 degree (contact surface c) at this example, and pawl contact 82 is to be formed with three contact surface A, B, C.Contact surface A, B, C have angle θ inequality according to the periphery angle position.Because of contact surface A, B, the tilt angle theta of C is inequality, therefore, drives power-transfer clutch and removes cam 80 and be contacted with pawl 71, and there then according to contact position wedge power is had to be inequality.
So,, lever is become smoothly by bell crank mechanism 90 (as following).Again, pawl 71 is to have bevelled contact surface 78, and when power-transfer clutch releasing cam 80 was contacted with this contact surface 78, pawl 71 was shaken as the center with pawl pin 74, the engagement between releasing pawl 71 and hook tooth 62.
It is the pin-and-holes 83 that are formed with semi arch that power-transfer clutch is removed cam 80, be inserted in wherein because of pin 85 runs through hub spindle 10, so the one binding has power-transfer clutch to remove cam 80 and hub spindle 10.Pin 85 is to be inserted in to bore a hole keyhole 84 in hub spindle 10 of diametric(al), and only certain distance is removable in this keyhole 84.Move to axis direction at the centre hole of hub spindle 10 and to be provided with push rod 86 freely.As a result, push rod 86 is to become to be linked to power-transfer clutch releasing cam 80.
The other end of push rod 86 is to be connected in bell crank mechanism 90.Bell crank mechanism 90 imposes driving with clutch control line 93.By the interior lines 92 of clutch control line 93, drive bell crank 91, in order to do driving push rod.The structure of this bell crank mechanism 91 is well-known, its explanation of Therefore, omited.As a result, when driving push rods 86 with clutch control line 93, then push rod 86 drives and drives clutch claw and remove cam 80 to axis direction, and this pawl contact surface 82 is contacted with the contact surface 78 of pawl 71 and removes the fastening of pawl 71 and hook tooth 62.
Remove by this angle,, therefore can become running as common bicycle because of being that system separates with the driving of electro-motor 15.On the contrary, when being interlocked with hook tooth 62 as if this pawl 71, then the driving of hub body 36 is passed to pawl 71 from hook tooth 62, and the result becomes the armature 19 that drives electro-motor 15.
As shown in the above description, the 1st miniature gears 30 of the output of electro-motor 15, planetary wheel 51, the 1st interior all teeth 44 of the pivot arm 33 of revolution and the annular gear wheel that is fixed are to constitute sun and planet gear, become differential gear train.Change speech, this differential gear train is the 1st speed reduction gearing of rotation that becomes the 1st miniature gears 30 of the output rotation that constitutes deceleration electric motor 15.
The output of the 1st speed reduction gearing is the rotation of output as the outer peripheral teeth 53 of gear frame 33.The output of the electro-motor 15 that is decelerated is that rotation drives the 2nd miniature gears 51.The 2nd miniature gears 51 is to become the 2nd interior all teeth 54 that rotation drives annular gear wheel.The number of teeth of cause the 2nd miniature gears 51 is to lack than the number of teeth of the 2nd interior all teeth 54, therefore, more is decelerated in this formation.This sun and planet gear is not constitute differential gear train, only becomes to constitute the 2nd speed reduction gearing.The rotation that is decelerated is via free-wheel clutch 60 rotation drive hub bodies 36.(action of mechanism's part)
Below, illustrate that this states the action of example.As shown in the above description, the 1st miniature gears 30 of the output shaft 16 of electro-motor 15, planetary wheel 31, the pivot arm 33 of revolution and the 1st interior all teeth 44 that are fixed are to constitute sun and planet gear, become differential gear train.Change speech, this differential gear train is the 1st used speed reduction gearing of rotation that becomes the 1st miniature gears 30 of the output rotation that constitutes deceleration electric motor 15.
The output of the 1st speed reduction gearing is the rotation of output as the outer peripheral teeth 53 of pivot arm 33.The output of the electro-motor 15 that is decelerated is that rotation drives the 2nd miniature gears 51.The 2nd miniature gears 51 is to become rotation to drive all teeth 54 in the 2nd.The number of teeth yarn of cause the 2nd miniature gears 51 lacks than the number of teeth of the 2nd interior all teeth 54, so at this, the rotation of electro-motor 15 becomes the state that more is decelerated.
This sun and planet gear is not constitute differential gear train only to become formation the 2nd speed reduction gearing.The rotation that is decelerated is to become the rotation drive hub body 36 via free-wheel clutch 60.Even free-wheel clutch 60 be stop pedal also can be only with the transmission of power of electro-motor 15 to wheel.When driving push rod 86 with clutch control line 93, push rod 86 moves and drives clutch claw releasing cam 80 to axis direction, makes this pawl contact surface 82 be contacted with the contact surface 78 of pawl 71 in order to do the fastening of releasing 71 with hook tooth 62.
Remove by this,, therefore can become running according to pedal operation as common bicycle because of being that system separates with the driving of electro-motor 15.On the contrary, if when this pawl 71 is interlocked with hook tooth 62, then the driving of hub body 36 is passed to pawl 71 from hook tooth 62, and the result becomes the armature 19 that drives electro-motor 15 and imposes dynamic brake.(moment of torsion detecting sensor 8)
The 7th, 8,9 figure are the detailed graphic of expression moment of torsion detecting sensor 8, the 7th figure is the front elevation that expression is contained in the moment of torsion detecting sensor of nipper wheel plate, the 8th (a) figure is the section-drawing of expression with VIII-VIII line sectility of the 7th figure, the 8th (b) figure is the section-drawing of expression with the VIII b-VIII b line sectility of the 7th figure, and the 9th (a) figure is the section-drawing of expression with the IX a-IX a line sectility of the 7th figure, and what the 9th (b) figure was expression when the arrow IX b of the 7th figure watches is graphic.

The 10th figure is the driving and the used motor driven and the brake control circuit 150 of dynamic brake of expression electro-motor 15.Micro computer and interface (being designated hereinafter simply as micro computer) the 151st, the chip of the central arithmetic processing apparatus of lift-launch, memory device, interface etc. on printed base plate.The structure that this is detailed, function are known, its explanation of Therefore, omited.Circuit for generating triangular wave 152 is in order to produce the chopping sea of frequency 15～20KHz.
The chopping sea that is produced is to input to comparator 153.The effect output signal 168 of anaiog signal is arranged from micro computer 151 outputs at comparator 153 on the one hand.Comparator 153 is along with the effect ratio exports pulse and door (an AND gate) 154 to.From micro computer 151 inputs the used regeneration instructions signal 155 of regenerative brake is arranged with door 154 at AND.
With door 154 output output from the pulse of comparator 153 is being arranged, and during from the regeneration instructions signal 155 of micro computer 151, then pulse output is being put on FET (effect electric crystal) actuator 156.When putting on this pulse output between the gate pole of FET157 and source electrode as reverse blas, drain current ID Be Controlled then.Drain current ID detects between the terminal A of resistance 158 of usefulness and B at electric current to be detected.
When sending the instruction of regenerative brake,, leakage current flow consumes as heat along with becoming at internal resistance.When FET157 disconnected (OFF), then electro-motor 15 was to become electric current is back to battery 2 via diode 158.When desire rotation drives electro-motor 15 then motor driven command signal 159 be output to AND door 160.
On the one hand, at AND door 160, along with effect has pulse than exporting from comparator 153.When the pulse output that has in AND door 160 output from comparator 153, and when driving from the used power running signal 159 of the electro-motor 15 of micro computer 151.Then pulse is exported to fet driver 161.When putting on this pulse output between the gate pole of FET162 and source electrode as reverse blas, drain electric current 163 Be Controlled then.
When output motor driven command signal 159, then there is drain current 163 to flow to electro-motor 15 and rotation driving electro-motor 15 from battery 2.Being connected in the electromagnetic switch 165 of micro computer 151, is the interior lines 92 of the clutch control line 93 that bell crank mechanism 90 moved in order to be pulled when imposing regenerative brake, makes it ON, the action of OFF.
It is used that proximity switch 171 is obtained the speed of a motor vehicle, detects the moment of torsion be located at wheel etc., detects the pulse as the per unit time.Potentiometer 172 is to detect the moment of torsion that is detected in above-mentioned moment of torsion detecting sensor 8, that is detects the moment of torsion of pedal 7.(regenerative brake action)
The following summary of the control action of the glancing impact of above-mentioned motor driven of explanation and brake control circuit 150.170 energisings (S1) of brake select switch are the indications of carrying out dynamic brake.Counting the unit time from the pulse count that proximity switch 171 is sent, obtain the present speed of a motor vehicle (S2).Judge whether the speed of a motor vehicle of being obtained is the setting maximum speed Smax (for example 25km/H) that determines in advance.When if maximum speed is above, then because of design speed above electro-motor 15, thus the so far above step of can not dividing a word with a hyphen at the end of a line, and do not make the regeneration brake.
If setting maximum speed when following, obtaining the present speed of a motor vehicle becomes synchronous speed with the speed that is produced according to electro-motor 15 sides rotation driving, obtain afterwards correspond to this speed effect than D (S4).Then, power running signal 159 is output (S5).So fet driver 161 is output and FET162 is become driving.Correspond to the effect output signal 168 of effect from micro computer 151 outputs afterwards than D.
As a result, drain current 163 flow to electro-motor 15 and only waited for for 0.5 second from battery 2 and makes electro-motor 15 become setting speed (S7).Electromagnetic switch 165 afterwards cuts off the power supply.By outage, because of push rod 86 is pushed axis direction to by coil spring 81, so pawl 71 and hook tooth 62 are interlocked.
Be interlocked by this pawl 71 and hook tooth 62, make the driving of front-wheel become the state that the drive system with electro-motor 15 is connected.That is when pawl 71 and hook tooth 62 were interlocked, then the driving of hub body 36 was passed to pawl 71 from hook tooth 62, and the result becomes the armature 19 that drives electro-motor 15 and becomes the state (S8) that can generate electricity and drive.
After this instruction, the temporary transient state (S9) that each above-mentioned mechanism is become instructed of waiting for.Through after this time, then with the rotative speed of electro-motor 15 only certain hour (was 0.5 second at this example) become the deceleration that control linearly makes.This deceleration is in order to reduce according to the following deceleration that regenerative brake produced institute with the acceleration/accel of accompanying.Afterwards, disconnect power running signal 159, stop the driving (S11) of electro-motor 15.
Then, when regenerative brake signal 155 was output, then the effect of the speed that is driven in rotation with the armature that corresponds to electro-motor 15 was reproduced braking than D.The electro-motor 15 that is driven in rotation is that generating electricly flow to battery 2 via diode 158 with electric current, becomes electrically-charged state.As mentioned above, in case at the preceding starting electro-motor 15 of carrying out regenerative brake, the rotative speed of rising electro-motor 15 is just carried out the regenerative brake action till becoming the present speed of a motor vehicle, so can prevent the anxious impact that brake is produced that swashs, also can prevent the acceleration of bearing.(constant speed brake)
Above-mentioned regenerative brake is only to generate electricity and impose to brake used action.Below illustrated, be to make the moving velocity of bicycle become certain speed in order to regenerative brake.The 13rd figure and the 14th figure are the diagram of circuits of expression constant speed regenerative brake.During with the down ramp in above-mentioned regenerative brake (S12 of the 12nd figure) ramp of travelling etc., if the constant speed regenerative brake selected then at first timer t started (S1).
The present speed of a motor vehicle of obtaining bicycle becomes consistent used effect ratio with the rotative speed of electro-motor 15, and this is exported as effect output signal 168, waited for for 0.5 second (S2, S3) through after 0.5 second, output regenerative brake signal 155 (S4).Then, read the on off state of brake select switch 170, that is whether read is arbitrary state (S5) of H or L.
If during brake select switch 170 selection mode H, the regenerative brake Cheng Jing setting speed 10km/H that is everlasting then.If during brake select switch 170 selection mode L, then often setting speed 7km/H is stored in fixed memory device.Afterwards, obtain present bicycle speed of a motor vehicle S (S9).Speed of a motor vehicle S is at below 1.2 times of setting speed (also comprising 1.2 times), and during 0.95 above (also comprising 0.95) (S10, S11, S13), then with the effect of last time than increasing by 0.8% (S13).
Speed of a motor vehicle S is more than 1.2 times of setting speed when (also comprising 1.2 times), then with the effect of last time than increasing by 1.7%.When speed of a motor vehicle S is below 1.2 times of setting speed (also 1.2 times), and during 0.8 following (also comprising 0.8) (S10, S11, S14), then with the effect of last time than reducing 1.7%.That is, because of the speed S of car body is lower than the speed that sets, so can relax regenerative brake (S16).
Speed of a motor vehicle S is below 1.2 times of setting speed (also comprising 1.2 times), and (S14 S15), then goes up effect than reducing 0.8% with the last time for S10, S11 during 0.95 following (also comprising 0.95).That is, because of the speed S of car body is lower than the speed that sets, so can relax regenerative brake (S17).When finishing above step, then can the scope of proportional limit built in 0.2 to 99 will be acted on.
As a result, can with speed of a motor vehicle S ad infinitum control rate setting speed 7 or 10km/H are become constant speed.This speed control degree is more satisfactory in situations such as down ramps.(deciding brake weight control)
The 15th figure is the diagram of circuit that the summary of power brake control action is decided in expression.Because of identical with above-mentioned constant speed brake till step S6, omit therefore that it is detailed.If during brake select switch 170 selection mode H, then regenerative brake makes the electric current of electro-motor 15 generatings become 15 amperes.If during brake select switch 170 selection mode L, then with 20 amperes be stored in fixed memory device.
Then, obtain the electric current I (S9) of present electro-motor (this state is an electrical generator) 15.Electric current I is below 1.2 times of setting speed (also comprising 1.2 times), and during 1.05 above (also comprising 1.05) (S10, S11, S13), then with the effect of last time than increasing by 0.8% (S13).That is, because of becoming, the electric current I with electro-motor 15 reduces 0.8%, so becoming, braking force is reduced.
If electric current I is more than 1.2 times of setting speed when (also comprising 1.2 times), then with the effect of last time than increasing by 1.7%.Electric current I is below 1.2 times of setting speed (also comprising 1.2 times), and during 0.8% following (also comprising 0.8%) (S10, S11, S14), then with the effect of last time than reducing 1.7%.That is, because of the electric current I of the generating of electro-motor 15 is lower than the electric current that sets, so can relax regenerative brake (S16).
Electric current I is below 1.2 times of setting speed (also comprising 1.2 times), and during 0.95 following (also comprising 0.95) (S10, S11, S14, S15), then with the effect of last time than reducing 0.8%.That is, because of electric current I is lower than the speed that sets, so can relax regenerative brake (S17).When finishing above quiet step, then can effect than becoming 0.2 to 99 the scope that is limited in.
As a result, the electric current of electro-motor 15 ad infinitum can be controlled to 20 amperes or 15 amperes to decide brake weight.Should fixed brake control be to become when necessarily imposing stopping that braking makes more satisfactory at degree of will speed up.Because of acceleration/accel is certain, so can successfully stop.Again, and if when using hand-operated brake, also can correctly stop at desired position.(other example)
Above-mentioned example is that electro-motor 15 is put in the wheel hubs, but is equipped on handle stem, front fork etc., and come transfer motion power also passable by belt drive, again, and technology as is well known, other positions that are disposed at beyond above-mentioned are also passable.
