In other words, the first camp forms 192 a first power transmission unit located between the hub shell 182 and the hub shaft 184 is arranged. Accurate forms at the first camp 192 the outer ring 250 that integrates with the hub housing 182 turns, a first electrical contact. The inner ring 248 that is at the hub shaft 184 through the bearing support member 266 is held and is carried so that a rotation relative to the hub shaft 184 is limited forms a second electrical contact.

The inner ring 254 that is at the hub shaft 184 is fixed, forms a fourth electrical contact. The second camp 194 electrically connects the third electrical contact and the fourth electrical contact with the rolling elements 258 , The second connection 270 contacts the outer ring 256 of the second camp 194 , Thus, the second port is 270 connected to the third electrical contact.

The distance in the circumferential direction between the radially outer end of the first terminal 268 and the radially outer end of the second terminal 270 is larger than the distance in the circumferential direction between the first insertion hole 294 and the second insertion hole 296 ,

The operation of the present embodiment will now be described.

First, the operations that affect the hub dynamo 180 refer described.

The rotation of the front wheel 14 turns the permanent magnet 218 relative to the anchor 216 , As a result, an electromagnetic induction generates alternating current in the coil 224 of the anchor 216 , The first supply wire 286 and the second lead wire 288 deliver that through the coil 224 generated AC power to the controller 44 , In the control 44 becomes the alternating current of the coil 224 through the converter 82 converted into direct current and the first conductive wire 88A of the first wire 88 fed.

The first conductive wire 88A supplies the control circuit 56 that integrates with the front wheel 14 turns, over the first camp 192 and the second conductive wire 88B with the direct current. Then the control circuit emits 56 Light from each of the light source units 48 . 50 . 52 . 54 ,

At the first camp 192 connect the rolling elements 252 the inner ring 248 that is not integral with the front wheel 14 turns, and the outer ring 250 that integrates with the front wheel 14 turns, electrically. At the second camp 194 connect the rolling elements 258 the inner ring 254 that is not integral with the front wheel 14 turns, and the outer ring 256 that integrates with the front wheel 14 turns, electrically. Thus, DC is from the controller 44 that are not integral with the front wheel 14 turns, the control circuit 56 fed, which is integral with the front wheel 14 rotates.

The operation of the light emitting units 42A . 42B will now be described.

For example, if the control circuit 56 Light from the first light source 58 the first light source unit 48 emitted, the light enters the first light source 58 in the first incidence area 136A of the first light guide element 136 one. The light that is in the first incidence area 136A occurs, is the reflection pattern 136D reflected, that at the first reflection surface 136B is formed, and emerges from the side surface of the first wheel cover 116A through the first light emission surface 136C and the first translucent cover 152 out. Thus, the light guide element emits 136 over the entire first light emission surface 136C Light in the circumferential direction. The second light guide element 138 , the third optical fiber element 140 and the fourth optical fiber element 142 emit light in the same way. Light appears to be from a ring through the light guide elements 136 . 138 . 140 . 142 emitted when the first wheel cover 116A viewed from the side surface.

In particular, light is apparently emitted from a ring when the first wheel cover 116A and the second wheel cover 116B from the side during the rotation of the front wheel 14 to be viewed as. If the front wheel 14 stops rotating, emit the first light source unit 48 and the second light source unit 50 for a certain period of time light due to the capacitor 84 the controller 44 which is charged when the front wheel 14 rotates. Even if the wheel 14 thus, light stops appearing to be emitted from a ring for a certain period of time when the first wheel cover stops 116A and the second wheel cover 116B be viewed from the side surface. The same operation is at the rear wheel 16 carried out.

The present embodiment has the following advantages.

• (1) Die Lichtemittiereinheit 42A umfasst die erste Lichtquelle 58, die sich integral mit dem Vorderrad 14 dreht, und das erste Lichtleiterelement 136, das sich integral mit dem Vorderrad 14 dreht. Solange die erste Lichtquelle 58 Licht emittiert, emittiert somit das erste Lichtleiterelement 136 in seiner Gesamtheit Licht. Somit hängt die visuelle Wirkung der Lichtemittiereinheit 42A nicht stark von der Drehgeschwindigkeit des Vorderrades 14 ab.
• (2) Die erste Lichtquelle 58 ist im Wesentlichen parallel zu einer Richtung, die zu der Drehachse des Vorderrades 14 orthogonal ist. Verglichen dazu, dass die erste Lichtquelle 58 das erste Lichtleiterelement 136 in einer Richtung parallel zur Drehachse des Vorderrades 14 bestrahlt, wird somit Licht von einem breiteren Bereich des ersten Lichtleiterelements 136 emittiert. Derselbe Vorteil wird durch die zweite Lichtquelle 60 und das zweite Lichtleiterelement 138, die dritte Lichtquelle 64 und das dritte Lichtleiterelement 140 und die vierte Lichtquelle 66 und das vierte Lichtleiterelement 142 erreicht.
• (3) Das erste Lichtleiterelement 136 verläuft entlang der Seitenfläche der ersten Radabdeckung 116A. Verglichen beispielsweise mit einer Ausbildung, in der das erste Lichtleiterelement 136 in einer Richtung parallel zur Drehachse des Vorderrades 14 verläuft, wird somit Licht von einem breiteren Bereich emittiert, wenn die erste Radabdeckung 116A von der Seite betrachtet wird. Derselbe Vorteil wird durch das zweite Lichtleiterelement 138, das dritte Lichtleiterelement 140 und das vierte Lichtleiterelement 142 erreicht.
• (4) Die Lichtemittiereinheit 42A umfasst des Weiteren die zweite Lichtquelle 60, die sich integral mit dem Vorderrad 14 dreht, und das zweite Lichtleiterelement 138, das sich integral mit dem Vorderrad 14 dreht. Somit kann ein breiterer Bereich Licht emittieren, wenn die erste Radabdeckung 116A von der Seitenfläche aus betrachtet wird. Die Lichtemittiereinheit 42A umfasst des Weiteren die dritte Lichtquelle 64 und die vierte Lichtquelle 66 und das dritte Lichtleiterelement 140 und das vierte Lichtleiterelement 142, so dass ein breiterer Bereich in der ersten Radabdeckung 116A Licht emittiert.
• (5) Das erste Lichtleiterelement 136 und das zweite Lichtleiterelement 138 sind in der Umfangsrichtung angeordnet. Dies verbreitert den Bereich, der Licht in der Umfangsrichtung emittiert, wenn die erste Radabdeckung 116A von der Seitenfläche aus betrachtet wird. Auch wenn das Vorderrad 14 mit einer geringeren Geschwindigkeit gedreht wird, erscheint somit der Bereich, der Licht emittiert, ohne weiteres als ein Ring.
• (6) Die erste Lichtquelle 58 und die zweite Lichtquelle 60 sind an dem ersten Montagesubstrat 62 montiert. Verglichen mit einem Aufbau, der Montagesubstrate umfasst, auf denen die erste Lichtquelle 58 und die zweite Lichtquelle 60 montiert sind, ist somit die Anzahl an Komponenten der Lichtemittiereinheit 42A reduziert. Ferner ist der Abstand in der Umfangsrichtung zwischen der ersten Einfallfläche 136A des ersten Lichtleiterelements 136 und der zweiten Einfallfläche 138A des zweiten Lichtleiterelements 138 verringert. Derselbe Vorteil wird auch durch die dritte Lichtquelle 64, die vierte Lichtquelle 66 und das zweite Montagesubstrat 68 erreicht.
• (7) Die Dicke des ersten Lichtleiterelements 136 ist von einem Ende, wo die erste Einfallfläche 136A ausgebildet ist, zum anderen Ende in der Umfangsrichtung verringert. Genauer ist die erste Reflektionsfläche 136B geneigt, um sich der optischen Achse der ersten Lichtquelle 58 von einem Ende zum anderen Ende hin anzunähern. Dies bestrahlt ohne weiteres das Reflektionsmuster 136D mit dem Licht von der ersten Lichtquelle 58. Somit tritt das Licht der ersten Lichtquelle 58 effizient aus der ersten Lichtemissionsfläche 136C aus. Derselbe Vorteil wird durch das zweite Lichtleiterelement 138, das dritte Lichtleiterelement 140 und das vierte Lichtleiterelement 142 erreicht.
• (8) Das Reflektionsmuster 136D an der ersten Reflektionsfläche 136B des ersten Lichtleiterelements 136 weist eine Dichteverteilung auf, die in der Umfangsrichtung variiert. Dies variiert den Grad des Lichts von der ersten Lichtquelle 58, das aus der ersten Lichtemissionsfläche 136C austritt. Derselbe Vorteil wird durch das zweite Lichtleiterelement 138, das dritte Lichtleiterelement 140 und das vierte Lichtleiterelement 142 erreicht.
• (9) Die Dichte des Reflektionsmusters 136D im dritten Bereich R3 der ersten Reflektionsfläche 136B ist kleiner als die Dichte des Reflektionsmusters 136D im ersten Bereich R1 der ersten Reflektionsfläche 136B und die Dichte des Reflektionsmusters 136D im zweiten Bereich R2. Dies verringert die Unterschiede beim Licht des ersten Bereichs R1 bis zum dritten Bereich R3, wenn das Licht der ersten Lichtquelle 58 aus der ersten Lichtemissionsfläche 136C austritt.
• (10) Das Steuersubstrat 132 wird durch die erste Radabdeckung 116A und die zweite Radabdeckung 116B gehalten. Somit kann der Steuerung 44 im Vergleich dazu miniaturisiert werden, wenn die Steuerung 44 das Steuersubstrat 132 umfasst.
• (11) Das Steuersubstrat 132 wird zwischen dem Abdeckungskörper 122 der ersten Radabdeckung 116A und dem Abdeckungskörper 122 der zweiten Radabdeckung 116B gehalten. Somit kann jede der Hauptflächen 132A, 132B des Steuersubstrats 132 entlang der axialen Richtung angeordnet werden. Dies ermöglicht es dem Steuersubstrat 132, den Speichern 28 des Vorderrads 14 aus dem Weg zu gehen.
• (12) Jeder der durchscheinenden Abdeckungen 152, 154, 156, 158 ist an die erste Radabdeckung 116A gekoppelt, um die erste Lichtquelleneinheit 48 und die zweite Lichtquelleneinheit 50 abzudecken. Dies begrenzt das Eindringen von Fremdkörpern, wie etwa Wasser und Staub, in die erste Lichtquelleneinheit 48 und die zweite Lichtquelleneinheit 50.
• (13) Das erste Befestigungselement 160 und das zweite Befestigungselement 162, die Licht abschirmende Eigenschaften aufweisen, sind an den Felgenkopplungsabschnitt 126 gekoppelt, um die erste Lichtquelleneinheit 48 bzw. die zweite Lichtquelleneinheit 50 abzudecken. Somit bleibt das Licht des ersten Lichtleiterelements 136 und des zweiten Lichtleiterelement 138 weiter außenstehend.
• (14) Jedes der Befestigungselemente 160, 162, 164, 166 ist mit dem Felgenkopplungsabschnitt 126 dadurch gekoppelt, dass die Haken 160A, 162A, 164A, 166A in die entsprechenden Kopplungslöcher 126A eingepasst sind. Dies erleichtert das Koppeln der Befestigungselemente 160, 162, 164, 166 an den Felgenkopplungsabschnitt 126, und ermöglicht es, dass die durchscheinenden Abdeckungen 152, 154, 156, 158 durch den Halteabschnitt 128 gehalten werden.
• (15) Die Lichtleiterelemente 136, 138, 140, 142, die bogenförmig sind, sind in der Umfangsrichtung angeordnet, um einen Ring zu bilden. Auch wenn die Drehgeschwindigkeit des Vorderrads 14 niedrig ist, emittieren somit die erste Radabdeckung 116A und die zweite Radabdeckung 116B jeweils Licht in der Form eines Rings.
• (16) Der Halteabschnitt 128 ist so ausgebildet, dass der erste Halteabschnitt 128A, der zweite Halteabschnitt 128B und der dritte Halteabschnitt 128C in dieser Reihenfolge in der Breite verkleinert sind. Somit ist jedes der Trageelemente 148, 150 und jedes der Lichtleiterelemente 136, 138, 140, 142 nicht an den dritten Halteabschnitt 128C gekoppelt. Ferner ist jeder der durchscheinenden Abdeckungen 152, 154, 156, 158 nicht an den zweiten Halteabschnitt 128B gekoppelt.
• (17) Der erste Halteabschnitt 128A, der zweite Halteabschnitt 128B und der dritte Halteabschnitt 128C sind in der axialen Richtung gesehen an überlappenden Positionen ausgebildet und weisen die Form von Nuten auf, die miteinander in Kommunikation sind. Dies vereinfacht die Form der ersten Radabdeckung 116A verglichen mit dem Fall, in dem der dritte Halteabschnitt 128C an der radial inneren Seite oder äußeren Seite des ersten Halteabschnitts 128A und des zweiten Halteabschnitts 128B ausgebildet ist.

The second wheel cover 116B and the light emitting unit 42B also have the same advantages.

• (1) The light emitting unit 42A includes the first light source 58 that integrates with the front wheel 14 rotates, and the first light guide element 136 that integrates with the front wheel 14 rotates. As long as the first light source 58 Emits light, thus emits the first light guide element 136 in its entirety light. Thus, the visual effect of the light emitting unit depends 42A not strong on the rotational speed of the front wheel 14 from.
• (2) The first light source 58 is substantially parallel to a direction parallel to the axis of rotation of the front wheel 14 is orthogonal. Compared to that the first light source 58 the first light guide element 136 in a direction parallel to the axis of rotation of the front wheel 14 Thus, light is irradiated from a wider area of the first light guide element 136 emitted. The same advantage is provided by the second light source 60 and the second optical fiber element 138 , the third light source 64 and the third optical fiber element 140 and the fourth light source 66 and the fourth optical fiber element 142 reached.
• (3) The first light guide element 136 runs along the side surface of the first wheel cover 116A , For example, compared with an embodiment in which the first optical fiber element 136 in a direction parallel to the axis of rotation of the front wheel 14 Thus, light is emitted from a wider area when the first wheel cover 116A viewed from the side. The same advantage is achieved by the second optical fiber element 138 , the third optical fiber element 140 and the fourth optical fiber element 142 reached.
• (4) The light emitting unit 42A further comprises the second light source 60 that integrates with the front wheel 14 rotates, and the second light guide element 138 that integrates with the front wheel 14 rotates. Thus, a wider area may emit light when the first wheel cover 116A viewed from the side surface. The light emitting unit 42A further includes the third light source 64 and the fourth light source 66 and the third optical fiber element 140 and the fourth optical fiber element 142 so that a wider area in the first wheel cover 116A Emitted light.
• (5) The first light guide element 136 and the second optical fiber element 138 are arranged in the circumferential direction. This widens the area that emits light in the circumferential direction when the first wheel cover 116A viewed from the side surface. Even if the front wheel 14 is rotated at a lower speed, thus, the area that emits light readily appears as a ring.
• (6) The first light source 58 and the second light source 60 are on the first mounting substrate 62 assembled. Compared with a structure comprising mounting substrates on which the first light source 58 and the second light source 60 are mounted, thus the number of components of the light emitting unit 42A reduced. Further, the distance in the circumferential direction is between the first incident surface 136A of the first light guide element 136 and the second incident surface 138A the second light guide element 138 reduced. The same advantage is also due to the third light source 64 , the fourth light source 66 and the second mounting substrate 68 reached.
• (7) The thickness of the first optical fiber element 136 is from an end where the first incidence area 136A is formed, reduced to the other end in the circumferential direction. Exactly the first one reflecting surface 136B inclined to the optical axis of the first light source 58 approach from one end to the other. This readily irradiates the reflection pattern 136D with the light from the first light source 58 , Thus, the light of the first light source occurs 58 efficient from the first light emission surface 136C out. The same advantage is achieved by the second optical fiber element 138 , the third optical fiber element 140 and the fourth optical fiber element 142 reached.
• (8) The reflection pattern 136D at the first reflection surface 136B of the first light guide element 136 has a density distribution that varies in the circumferential direction. This varies the degree of light from the first light source 58 that is from the first light emission surface 136C exit. The same advantage is achieved by the second optical fiber element 138 , the third optical fiber element 140 and the fourth optical fiber element 142 reached.
• (9) The density of the reflection pattern 136D in the third region R3 of the first reflection surface 136B is smaller than the density of the reflection pattern 136D in the first region R1 of the first reflection surface 136B and the density of the reflection pattern 136D in the second area R2. This reduces the differences in the light of the first region R1 to the third region R3 when the light of the first light source 58 from the first light emission surface 136C exit.
• (10) The control substrate 132 gets through the first wheel cover 116A and the second wheel cover 116B held. Thus, the controller 44 In comparison, miniaturized when the controller 44 the control substrate 132 includes.

This allows the control substrate 132 , the save 28 of the front wheel 14 to get out of the way.
• (12) Each of the translucent covers 152 . 154 . 156 . 158 is at the first wheel cover 116A coupled to the first light source unit 48 and the second light source unit 50 cover. This limits the penetration of foreign matter such as water and dust into the first light source unit 48 and the second light source unit 50 ,
• (13) The first fastener 160 and the second fastening element 162 that have light-shielding properties are at the rim coupling portion 126 coupled to the first light source unit 48 or the second light source unit 50 cover. Thus, the light of the first light guide element remains 136 and the second optical fiber element 138 further outward.
• (14) Each of the fasteners 160 . 162 . 164 . 166 is with the rim coupling section 126 coupled by that the hook 160A . 162A . 164A . 166A into the corresponding coupling holes 126A are fitted. This facilitates the coupling of the fasteners 160 . 162 . 164 . 166 to the rim coupling section 126 , and allows the translucent covers 152 . 154 . 156 . 158 through the holding section 128 being held.
• (15) The light guide elements 136 . 138 . 140 . 142 which are arcuate are arranged in the circumferential direction to form a ring. Even if the rotational speed of the front wheel 14 is low, thus emit the first wheel cover 116A and the second wheel cover 116B each light in the form of a ring.
• (16) The holding section 128 is formed so that the first holding portion 128A , the second holding section 128B and the third holding section 128C are reduced in width in this order. Thus, each of the support elements 148 . 150 and each of the light guide elements 136 . 138 . 140 . 142 not on the third holding section 128C coupled. Further, each of the translucent covers 152 . 154 . 156 . 158 not on the second holding section 128B coupled.
• (17) The first holding section 128A , the second holding section 128B and the third holding section 128C are formed at overlapping positions when viewed in the axial direction and have the shape of grooves communicating with each other. This simplifies the shape of the first wheel cover 116A compared with the case where the third holding portion 128C on the radially inner side or outer side of the first holding portion 128A and the second holding portion 128B is trained.

Daher wird die Umfangslänge jedes der Lichtleiterelemente 136, 138, 140, 142 erhöht.
• (20) Das Steuersubstrat 132 ist an einer Position benachbart zum ersten Montagesubstrat 62 angeordnet. Dies verkürzt den zweiten Draht 90, der das Steuersubstrat 132 und das erste Montagesubstrat 62 verbindet.
• (21) Die Drahtgruppe 46A ist mit den Hauptflächen 132A, 132B des Steuersubstrats 132 verbunden. Somit ist die Größe des Steuersubstrats 132 im Vergleich damit verringert, wenn die Drahtgruppe 46A mit nur einer Fläche des Steuersubstrats 132 verbunden ist.

• (24) Der erste Anschluss 268 und der zweite Anschluss 270 sind in dem Nabengehäuse 182 angeordnet. Somit ist es weniger wahrscheinlich, dass sich Wasser an dem ersten Anschluss 268 und dem zweiten Anschluss 270 ansammelt, verglichen damit, dass der erste Anschluss 268 und der zweite Anschluss 270 außerhalb des Nabengehäuses 182 angeordnet sind. Dies begrenzt die Korrosion des ersten Anschlusses 268 und des zweiten Anschlusses 270.
• (25) Die Anschlusseinheit 264 umfasst das Anschlusshalteelement 272, das elektrisch isolierende Eigenschaften aufweist und den ersten Anschluss 268 und den zweiten Anschluss 270 hält. Dies löst die Verbindung des ersten Anschlusses 268 und des zweiten Anschlusses 270.
• (26) Der zweite Anschluss 270 ist zwischen dem Anschlusshalteelement 272 und dem ersten Lagersitz 244 der Halterung 204 gehalten. Somit sind der zweite Anschluss 270 und das Anschlusshalteelement 272 fixiert, ohne die Notwendigkeit einer Form oder eines Verfahrens, die dazu bestimmt sind, den zweiten Anschluss 270 und das Anschlusshalteelement 272 zu fixieren. Dies vereinfacht die Formen des zweiten Anschlusses 270 und des Anschlusshalteelements 272.

• (30) Bei dem ersten Begrenzungsmechanismus 230 ist jeder der drei Drehstoppelemente 234E der ersten Halteplatte 234 zwischen benachbarten ersten Klauen 226 in der Umfangsrichtung eingepasst. Dies begrenzt eine Bewegung in der Umfangsrichtung der ersten Halteplatte 234 relativ zu den ersten Klauen 226. Daher wird an dem ersten Zuleitungsdraht 286 und dem zweiten Zuleitungsdraht 288, die in das Einsteckloch 234B der ersten Halteplatte 234 eingesteckt sind, nicht durch die Umfangsbewegung der ersten Halteplatte 234 gezogen.

Dies begrenzt die Drehung der Feststellmutter 238. Wenn eine Drehung der Feststellmutter 238 die Feststellmutter 238 von der zweiten Halteplatte 236 weg in der axialen Richtung bewegt, wird die Bewegung der ersten Halteplatte 234 und der zweiten Halteplatte 236 in der axialen Richtung begrenzt.

• (19) Each of the main surfaces 62A . 62B of the first mounting substrate 62 and each of the main surfaces 68A . 68B of the second mounting substrate 68 are arranged parallel to the axial direction. This reduces the distance in the circumferential direction between the first optical fiber element 136 and the second optical fiber element 138 and the distance between the third optical fiber element 140 and the fourth optical fiber element 142 , Therefore, the circumferential length of each of the light guide elements becomes 136 . 138 . 140 . 142 elevated.
• (20) The control substrate 132 is at a position adjacent to the first mounting substrate 62 arranged. This shortens the second wire 90 that the tax substrate 132 and the first mounting substrate 62 combines.

This provides an electrical connection between the hub shell 182 and the hub shaft 184 with the second camp 194 for sure. Furthermore, the rotational resistance of the hub shell 182 In comparison, this reduces the hub shell 182 and the hub shaft 184 be electrically connected to a metal contact, which slides like a sliding ring.
• (24) The first connection 268 and the second connection 270 are in the hub shell 182 arranged. Thus, it is less likely that water will be on the first port 268 and the second port 270 accumulates, compared with that the first connection 268 and the second connection 270 outside the hub shell 182 are arranged. This limits the corrosion of the first port 268 and the second port 270 ,
• (25) The connection unit 264 includes the terminal holding member 272 which has electrically insulating properties and the first terminal 268 and the second port 270 holds. This triggers the connection of the first port 268 and the second port 270 ,

Thus, the second connection 270 and the terminal holding member 272 fixed, without the need for a mold or a method intended to make the second connection 270 and the terminal holding member 272 to fix. This simplifies the shapes of the second port 270 and the terminal holding member 272 ,
• (27) The first lead wire 286 and the second lead wire 288 are in the wire receiving section 186 the hub shaft 184 added. Thus, the first lead wire can 286 and the second lead wire 288 easily from the hub shell 182 extend.

This limits the separation of the rotary stop element 234E the first holding plate 234 from the first claws 226 that would be causing the first retaining plate 234 from the first claws 226 moved away in the axial direction.
• (32) The recess 280A of the bearing holding element 266 is to the second holding plate 236 fit. The second holding plate 236 is at the first holding plate 234 fixed, and the rotation of the second holding plate 236 is through the rotation stop element 234E the first holding plate 234 limited.

• (35) At the first connection 268 is the contact section 268A who is the outer ring 250 of the first camp 192 contacted, bent. Thus, the contact section presses 268A constant against the outer ring 250 , This keeps the first connection 268 and the second camp 192 stable in contact with each other.
• (36) At the second port 270 is the contact section 270D who is the outer ring 256 of the second camp 194 contacted, bent. Thus, the contact section presses 270D constant against the outer ring 256 , This holds the second port 270 and the second camp 194 stable in contact with each other.
• (37) The power supply device 170 includes the capacitor 84 , Thus, the capacitor supplies 84 each of the light source units 48 . 50 . 52 . 54 with DC, even if the front wheel 14 stops turning and the hub dynamo 180 does not generate an alternating current. Thus, each of the light source units emits 48 . 50 . 52 . 54 light for a certain period of time, even after the front wheel 14 stops turning.
