Here, in the embodiment shown, the hub assembly 10 is a bicycle hub. More specifically, the hub assembly 10 is a rear bicycle hub. Also here, in the embodiment shown, the hub assembly 10 is a hub dynamo for providing electrical power to one or more components of the bicycle V. However, the hub assembly 10 is not limited to a hub dynamo. In particular, certain aspects of the hub assembly 10 that do not generate electrical power may be provided. While hub assembly 10 is illustrated as a rear hub assembly, certain aspects of hub assembly 10 may be provided on a front hub assembly. Thus, the hub assembly 10 is not limited to a rear hub assembly.

Here, the bicycle V is an electrically assisted bicycle (e-bike). Alternatively, the bicycle V can be a racing bike, a city bike, a cargo bike, a recumbent bike, or another type of off-road bike, such as a cyclocross bike. As in 1 1, the bicycle V includes a vehicle body VB supported by a rear wheel RW and a front wheel FW. The vehicle body VB basically includes a front frame body FB and a rear frame body RB (a swingarm). The vehicle body VB is also provided with a handlebar H and a front fork FF for steering the front wheel FW. The rear frame body RB is swingably mounted to a rear portion of the front frame body FB such that the rear frame body RB can pivot with respect to the front frame body FB. The rear wheel RW is mounted at a rear end of the rear frame body RB. A rear shock absorber RS is operatively interposed between the front frame body FB and the rear frame body RB. The rear shock absorber RS is provided between the front frame body FB and the rear frame body RB to control the movement of the rear frame body RB with respect to the front frame body FB. Namely, the rear shock absorber RS absorbs shocks transmitted from the rear wheel RW. The rear wheel RW is rotatably mounted on the rear frame body RB. The front wheel FW is mounted to the front frame body FB via the front fork FF. Namely, the front wheel FW is mounted to a lower end of the front fork FF. A height adjustable seat post ASP is conventionally mounted to a seat tube of the front frame body FB and supports a bicycle seat or saddle S in any suitable manner. The front fork FF is pivotally mounted to a head tube of the front frame body FB. The handlebar H is mounted to an upper end of a steering column or a steerer tube of the front fork FF. The front fork FF absorbs shocks transmitted from the front wheel FW. The rear shock absorber RS and the front wheel fork FF are preferably electrically adjustable springs. For example, the stiffness and/or stroke length of rear shock absorber RS and front fork FF can be adjusted.

The bicycle V further includes a drivetrain DT and an electric drive unit DU operatively coupled to the drivetrain DT. Here, for example, the powertrain DT is a chain drive type including a crank C, a front sprocket FS, a plurality of rear sprockets CS, and a chain CN. The crank C includes a crank axle CA1 and a pair of crank arms CA2. The crank axle CA1 is rotatably supported on the front frame body FB via the electric drive unit DU. The crank arms CA2 are provided at opposite ends of the crank axle CA1. A pedal PD is rotatably coupled to the distal end of each of the crank arms VA2. The drive train DT can be selected from all types, and can be of the belt drive or shaft drive type.

The electric drive unit DU has an electric motor that provides a drive assist force to the front gear FS. The electric drive unit DU can be actuated to assist in the propulsion of the bicycle V in a conventional manner. The electric drive unit DU is actuated according to a human driving force applied to the pedals PD, for example. The electric drive unit DU is actuated by electric power supplied from a main battery pack BP mounted on a down tube of the bicycle V. The main battery pack BP can supply electric power to other vehicle components such as the rear derailleur RD, the height adjustable seat post ASP, the rear shock absorber RS, the front fork FF, and any other vehicle component that uses electric power.

The bicycle V also includes a bicycle computer SC. Here, the cycle computer SC is mounted on the front frame body FB. Alternatively, the cycle computer SC may be provided on the handlebar H. The cycle computer SC notifies the driver of various locomotion and/or operating states of the cycle V. The cycle computer SC can also include various control programs for automatically controlling one or more vehicle components. For example, the cycle computer SC may be provided with an automatic shift program for changing gears of the rear derailleur RD based on one or more travel and/or operating conditions of the bicycle V.

Here, the bicycle V further includes a rear derailleur RD fixed to the rear frame body RB to shift the chain CN between the rear sprockets CS. The rear derailleur RD is one type of gear change device. Here, the rear derailleur RD is an electric derailleur (ie, an electric speed change device or an electric transmission device). Here, the rear derailleur RD is provided on the rear side of the rear frame body RB near the hub assembly 10 . The rear derailleur RD can be operated when a rider of the bicycle V manually operates a gear shift operating device or shifting device SL. The rear derailleur RD may also be actuated automatically based on travel conditions and/or bicycle V operating conditions. The bicycle V may further include a plurality of electronic components. Some or all of the electronic components may be powered by electrical power generated by hub assembly 10 during a power generation condition, as discussed herein.

The structure of hub assembly 10 will now be described with particular reference to FIG 2 until 5 described. The hub assembly includes a hub axle 12 and a hub body 14. The hub axle 12 is configured to be non-rotatably fixed to the vehicle body VB. In this embodiment, the hub axle 12 is configured to be non-rotatably fixed to the rear frame body RB. The hub body 14 is rotatably supported on the hub axle 12 to rotate about a rotation center axis A1 of the hub assembly 10 . The hub axle 12 has a center axis that is coaxial with the rotation center axis A1. The hub body 14 is rotatably arranged around the rotation center axis A1. In other words, the hub body 14 is rotatably supported around the hub axle 12 .

As in the 3 and 8th As can be seen, the hub axle 12 is a rigid member made of a suitable material, such as a metallic material. The hub axle 12 has a first axial end 12a and a second axial end 12b. Here, the hub axle 12 is a tubular member. Thus, the hub axle 12 has an axial bore 12c extending between the first axial end 12a and the second axial end 12b. The hub axle 12 may be a one-piece member or may be fabricated from multiple pieces.

Here's how in the 2 until 4 1, the hub axle shaft 12 is provided with an end fitting or end cap 16. As shown in FIG. The end cap 16 is attached to the first axial end 12a (right side in Figs 2 until 5 ) of the hub axle shaft 12 mounted. A nut 18 is fitted onto the hub axle 12 from the second axial end 12b (left side in Figs 2 until 5 ) screwed onto the hub axle shaft 12. Here, the end cap 16 is fixed to the first axial end 12a of the hub axle 12 by a fixing bolt 20 screwed into the axial bore 12c of the hub axle 12 . In this way, the end cap 16 and the fixing bolt 20 are accommodated in mounting holes of the rear frame body RB, as shown in FIG 2 to see. Here, the end cap 16 includes a rotation restricting part 16a which is also received in one of the mounting holes of the rear frame body RB. The rotation restricting part 16 is engaged with the rear frame body RB so that rotation of the hub axle 12 relative to the rear frame body RB is restricted.

Includes here, as in the 2 and 3 1, the hub assembly 10 further includes a wheel retaining mechanism 22 for securing the hub axle 12 of the hub assembly 10 to the rear frame body RB. The wheel holding mechanism 22 basically comprises a shaft or tensioner 22a, a cam body 22b, a cam lever 22c and an adjustment nut 22d. The cam lever 22c is fixed to one end of the tensioner 22a via the cam body 22b, while the adjustment nut 22d is screwed onto the other end of the tensioner 22a. The lever 22c is fixed to the cam body 22b. Cam body 22b is coupled between tensioner 22a and cam lever 22c to move tensioner 22a relative to cam body 22b. Thus, the lever 22c is operated to move the tensioner 22a in the axial direction of the rotation center axis A1 with respect to the cam body 22b to vary the clearance between the cam body 22b and the adjusting nut 22d. Preferably, a compression spring is provided at each end of the tensioner 22a. Alternatively, the hub axle 12 may be non-rotatably attached to the rear frame body RB with other attachment structures as needed and/or desired.

As in the 1 and 5 1, the hub body 14 is rotatably supported around the hub axle 12 to rotate in a driving rotational direction D1. The drive rotation direction D1 corresponds to a forward drive direction of the rear wheel RW. The hub body 14 is designed to support the rear wheel RW in a conventional manner. More specifically, in the embodiment shown, the hub body 14 includes a first outer flange 14a and a second outer flange 14b. The first outer flange 14a and the second outer flange 14b extend radially outward from a peripheral surface of the hub body 14 with respect to the rotation center axis A1. The first outer flange 14a and the second Outer flange 14b are formed, a plurality of spokes ( 1 ) to record a rim ( 1 ) of the rear wheel RW to the hub body 14 to be fixed. In this way, the hub body 14 and the rear wheel RW are coupled to rotate together.

As in the 4 and 5 As can be seen, the hub body 14 has a large opening 14c which receives a coupler body 24 and a retainer or snap ring 26 . The coupling body 24 is engaged with the hub body 14 in a rotationally fixed manner. The coupling body 24 is thus coupled to the hub body 14 in a torque-proof manner. The coupling body 24 is held to the hub body 14 by the snap ring 26 . Here, for example, the retaining ring 26 is screwed into the hub body 14. Thus, the snap ring 26 is removably coupled to the hub body 14 . The coupling body 24 has an inner peripheral surface 24b fixed to a fixing member 28 .

The fixing member 28 is a tubular member having a first end portion 28a and a second end portion 28b. The first end portion 28a abuts against an inner body 30 . The second end portion 28b is coupled to the coupling body 24 . More precisely, the second end section 28b has an external thread for fastening the coupling body 24 to the fixing element 28 . The fixing element 28 thus represents a tubular fixing bolt. In this way, the inner body 30 is coupled to the hub body 14 in a torque-proof manner. The hub body 14, the coupling body 24, the snap ring 26, the fixing member 28 and the inner body 30 rotate together as a unit about the hub axle 12.

As in the 3 and 4 1, the hub assembly 10 further includes a first bearing 31. The first bearing 31 supports the hub body 14 for rotation. Preferably, the hub assembly 10 further includes a second bearing 32 that rotatably supports one end of the hub body 14 . The first bearing 31 rotatably supports the other end of the hub body 14 with respect to the rotational center axis A1. The first bearing 31 and the second bearing 32 are angular contact ball bearings. Angular contact ball bearings have inner and outer ring raceways that are shifted relative to each other in the direction of the bearing axis. In other words, angular contact bearings are designed to carry combined loads, ie radial and axial loads acting simultaneously. Further, angular contact roller bearings (ie, tapered roller bearings) may be selected for the first bearing 31 and the second bearing 32 instead of the angular contact ball bearings. Angular contact bearings include cylindrical roller bearings and needle roller bearings.

Here, the hub assembly 10 further includes a gear support body 34. In the embodiment shown, the gear support body 34 supports the rear gears CS as shown in FIG 2 to see. The gear support body 34 is rotatably arranged around the rotation center axis A1 to transmit a driving force to the hub body 14 while rotating in a drive rotation direction D1 around the rotation center axis A1. As discussed below, the gear bearing body 34 transmits no driving force to the hub body 14 while rotating in a non-driving rotational direction D2 about the rotational center axis A1. The non-drive rotational direction D2 is opposite to the drive rotational direction D1 with respect to the rotational center axis A1. The rotational center axis of the gear bearing body 34 is arranged concentrically with the rotational center axis A<b>1 of the hub assembly 10 .

While the gear support body 34 is configured to non-rotatably support the rear gears CS, the gear support body 34 is not limited to the illustrated embodiment. Alternatively, one or more of the gears CS may be integrally formed with the gear support body 34 . In any case, the gear support body 34 and the rear gears CS are coupled to rotate together in both the driving rotational direction D1 and the non-driving rotational direction D2.

The hub assembly 10 further includes a plurality of first rolling elements 36 and a plurality of second rolling elements 38. The first rolling elements 36 and the second rolling elements 38 rotatably support the gear bearing body 34. The first rolling elements 36 are interposed between an outer ring of the first bearing 31 and the gear bearing body 34 . Specifically, the outer ring of the first bearing 31 has an inner ring surface, and the gear bearing body 34 has an outer ring surface. The first rolling elements 36 are arranged between the gear bearing body 34 and the first bearing 31 to form a first gear bearing body bearing 40 . The second rolling elements 38 are arranged between the inner body 30 and the gear bearing body 34 . Specifically, the inner body 30 has an inner ring surface and the gear bearing body 34 has an outer ring surface. The second rolling elements 38 are disposed between the inner body 30 and the gear bearing body 34 to form a second gear bearing body bearing 42 . The first gear bearing body bearing 40 and the gear bearing body bearing 42 are angular ball bearings. Further, angular contact bearings (ie tapered roller bearings) can be used in place of the angular contact ball bearings for the first Gear bearing body bearing 40 and / or the second gear bearing body bearing 42 are selected.

As in 4 As can be seen, the hub assembly 10 further includes a one-way clutch 44 formed between the inner body 30 and the gear bearing body 34 . As mentioned above, the inner body 30 is rotationally coupled to the hub body 14 . Thus, the one-way clutch 44 is operatively disposed between the hub body 14 and the gear bearing body 34 . In this way, the gear support body 34 and the hub body 14 rotate together in the driving rotation direction D1 about the rotation center axis A1. On the other hand, the gear support body 34 and the hub body 14 can rotate relative to each other, with the gear support body and the hub body 14 being rotated in opposite directions.

The one-way clutch 44 includes a plurality of pawls 44A disposed between the inner body 30 and the gear bearing body 34 . The one-way clutch 44 further includes a pair of biasing members 44B that couples the pawls 44A to the gear bearing body 34 . In this embodiment, the pair of biasing members 44B couples the pawls 44A to the inner body 30. The one-way clutch 44 further includes a plurality of ratchet teeth 44C. Here, the ratchet teeth 44C are provided on the internal surface of the gear bearing body 34 . The biasing members 44B bias the pawls 44A into engagement with the ratchet teeth 44C. The biasing members 44B urge the pawls 44A against the gear support body 34 such that the pawls 44A pivot toward engagement with the ratchet teeth 44C.

In this way, the gear support body 34 is coupled to the hub body 14 to rotate together in the driving rotation direction D1 about the rotation center axis A1. In a case where the gear support body 34 is rotated in the non-driving rotational direction D2, the ratchet teeth 44C of the gear support body 34 also press against the pawls 44A and pivot the pawls 44A to a retracted position against the gear support body 34. Thus, the gear support body 34 is formed to rotate relative to the hub body 14 in the non-drive rotational direction D2 about the rotational center axis A1. In this way, the gear bearing body 34 and the one-way clutch 44 form a one-way clutch commonly used on bicycles. Since the basic operation of the freewheel is relatively conventional, the freewheel will not be discussed or illustrated in further detail.

As in the 7 and 8th 1, the hub assembly 10 includes a component assembly 50. Thus, the component assembly 50 for the human-powered vehicle V is provided. While the component assembly 50 is illustrated as part of the hub assembly 10, it will be appreciated from this disclosure that the component assembly 50 may be used with other vehicle assemblies. Here, the component assembly 50 basically includes an axle shaft, a unit, and a fixing plate. In the case of the hub assembly 10, the component assembly 50 basically includes the hub axle 12, a unit 52, and a locating plate 54. Thus, in the case of the hub assembly 10, the hub assembly 10 includes a hub body 14 that is rotatably supported on the hub axle 12 for about the Rotational center axis A1 of the hub assembly 10 to rotate. In simple terms, the axle shaft (eg, hub axle 12) has a central axis, a first axial end, and a second axial end opposite to the first axial end in an axial direction with respect to the central axis. As mentioned above, in the case of the hub assembly 10, the hub axle 12 has the rotational center axis A1, the first axial end 12a and the second axial end 12b.

In the embodiment shown, unit 52 is an electrical unit. In particular, the assembly 52 includes an electrical component 60 . In the embodiment shown, the hub assembly 10 further includes the assembly 52 that includes an armature 62 . Electrical component 60 and armature 62 are electrically connected, as explained below. The locating plate 54 is disposed between the electrical component 60 and the armature 62 to non-rotatably couple the electrical component 60 and the armature 62 to the hub axle 12 . Thus, while the hub body 14 rotates relative to the hub axle 12, the electrical component 60 and the armature 62 remain stationary.

The electric component 60 is arranged in the hub body 14 between the hub axle 12 and the hub body 14 in the radial direction with respect to the rotation center axis A1. Here, the electrical component 60 includes a housing 64. The housing 64 is non-rotatably coupled to the hub axle 12 by the locating plate 54, which is splined to the hub axle 12. As shown in FIG. Basically, the case 64 comprises a case body 64A and a lid 64B. Here, the lid 64B is bonded to the case body 64A by adhesive or welding. However, the lid 64 may be secured to the housing body 64A by a threaded fastener, rivets, etc. Preferably, the housing body 64A and the cover 64B are rigid members consisting of a suitable material are made. For example, the case body 64A and the lid 64B are made of a resin material. For example, the case body 64A and the lid 64B may each be injection molded members.

The electrical component 60 also includes an electrical circuit board 66. The electrical circuit board 66 is disposed within the housing 64. As shown in FIG. Specifically, the electric circuit board 66 is fixed to the case body 64A. In this way, the electrical circuit board 66 is rotationally fixed with respect to the hub axle 12 . The electric circuit board 66 is arranged perpendicularly to the rotation center axis A1. The cover 64B is attached to the case body 64A to enclose the electrical circuit board 66 in the case 64. As shown in FIG.

The electrical circuit board 66 also includes an electronic control device 68 which is provided on the electrical circuit board 66 . The electronic control device 68 includes at least one processor that executes specified control programs. The at least one processor may be a central processing unit (CPU) or a micro processing unit (MPU), for example. As used herein, the term "electronic controller" refers to hardware that executes a software program and does not include a human. The electric circuit board 66 preferably further includes a data storage device (memory) provided on the electric circuit board 66 . The data storage device (memory) stores various control programs and information used for various control processes including power generation control, power storage control, hub rotation detection control, etc.

Data storage device 70 includes any computer storage device or non-transitory, computer-readable medium with the sole exception of a transient, propagated signal. The data storage device 70 includes, for example, a non-volatile memory and a volatile memory. The non-volatile memory includes, for example, at least one of a read-only memory (ROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only Memory (electrically erasable programmable read-only memory, EEPROM) and a flash memory. The volatile memory includes, for example, random access memory (RAM). The data storage device 70 stores various control programs and information used for various control processes including power generation control, power storage control, hub rotation detection control, etc.

As in 5 As shown, the electric component 60 further includes a detected part 71 and a rotation detection sensor 72. Here, the detected part 71 is provided on the gear bearing body 34. As shown in FIG. On the other hand, the rotation detection sensor 72 is arranged in the case 64 . In this way, the rotation detection sensor 72 is non-rotatable with respect to the hub axle 12 . The rotation detection sensor 72 is electrically connected to the electric circuit board 66 . As in 5 As shown, the rotation detection sensor 72 is disposed within the hub body 14 at a location spaced radially outward from the hub body 12 .

In the shown embodiment, the rotation detection sensor 72 includes a magnetic sensor, and the detected part 71 includes a magnet. Thus, the magnetic sensor detects movement of the magnet rotating together with the gear bearing body 34 . In other words, with this arrangement, the rotation detection sensor 72 is configured to detect the detected part 71 to detect rotation of the gear support body 34 around the rotation center axis A1. The rotation detection sensor 72 is electrically connected to the electronic controller 68 via the electrical circuit board 66 . The electronic control device 68 is designed to receive a detection signal from the rotation detection sensor 72 . Thus, the electronic controller 68 can determine information regarding the rotation of the gear bearing body 34 on the hub axle 12 .

Here, the magnet of the detected part 71 is an annular member having alternating S-pole sections and N-pole sections. The detected part 71 is fixed to the gear bearing body 34 . In this way, the rotation detection sensor 72 can detect a rotation amount and a rotation direction of the gear support body 34 . However, the detected part 71 is not limited to the illustrated annular member. For example, the detected part 71 may be formed of a single non-annular magnet, or two or more magnets circumferentially spaced around the rotation center axis A1. In the case of using two or more circumferentially spaced magnets, a back yoke may be provided, and the circumferentially spaced magnets may be provided on the back yoke. In this way, the circumferentially spaced magnets can be easily installed in the hub assembly 10 . The term "sensor" as used herein means a hardware device or instrument designed to detect the presence or absence of a specific event, object, substance or change in its environment and to emit a signal in response. The term "sensor" as used herein does not include a human.

The coupling body 24 is formed at least partially from a non-magnetic material or has an opening. For example, the non-magnetic material includes austenitic stainless steel, high manganese steel, high nickel alloy, aluminum and copper. Non-magnetic materials allow lines of magnetic force to pass through them. As in 5 As can be seen, the coupling body 24 is made of a non-magnetic material such as a hard resin material and aluminum alloys. Thus, the magnetic force of the detected part 71 passes through the coupling body 24 and reaches the rotation detection sensor 72.

An electrical cable 74 is electrically connected to the electrical circuit board 66 of the electrical component 60 . Electrical cable 74 passes axially through a gap between gear bearing body 34 and hub axle 12. More specifically, in the embodiment shown, hub axle 12 includes an axially extending recess or groove 12 for receiving electrical cable 74. Thus, groove 12d provides a cable receiving channel The axially extending recess or groove 12d extends at least from the first axial end 12a inwardly of the housing 64 of the electrical component 60. In this manner, the hub axle 12 includes a cable receiving channel extending axially between the electrical component 60 and the first axial End 12a of the hub axle 12 extends. Here, the groove 12d extends from the first axial end 12b to the anchor 62, but does not extend beyond the anchor 62. The electrical cable 74 extends out of the hub assembly 10 and is electrical to another electrical component of the human-powered vehicle V connected, such as to the rear derailleur RD, the battery pack BP, or an electrical junction box. As explained later, the electrical cable 74 may supply electrical power generated by the hub assembly 10 to the rear derailleur RD, the battery pack BP, or another electrical component.

As in 4 As can be seen, the hub assembly 10 further includes an electric power generator 76 disposed within the hub body 14 . More specifically, the electric power generator 76 is disposed in the hub body 14 between the hub axle 12 and a central portion of the hub body 14 . The electric power generator 76 is configured to generate electric power by rotating the hub body 14 . The electric circuit board 66 is electrically connected to the electric power generator 76 by a pair of electric wires 78 . In this way, the electrical wires 78 electrically connect the electrical component 60 to the electrical power generator 76 so that the electrical component 60 can receive electrical power from the electrical power generator 76 . The rotation detection sensor 72 receives electric power from the electric power generator 76.

In the embodiment shown, electrical component 60 also includes at least one capacitor 80 electrically connected to electrical power generator 76 . Here, the electrical component 60 includes two capacitors 80 electrically connected to the electrical power generator 76 . Capacitors 80 are examples of an electrical power storage device of electrical component 60 . Capacitors 80 are preferably disposed within housing 64 of hub assembly 10 . Thus, the capacitors 80 are rotatably supported on the hub axle 12 by the housing 64 . The electric circuit board 66 is electrically connected to the rotation detection sensor 72 and the capacitors 80 . In this way, the capacitors 80 provide electrical power to the electrical circuit board 66 and other electrical components that are electrically connected to the electrical circuit board 66 . For example, the capacitors 80 provide electrical power to the rotation detection sensor 72 . Also, the electronic controller 68 of the electrical circuit board 66 is configured to control the input and output of electrical power from the capacitors 80 .

The electric power generator 76 basically comprises the armature 62 and a rotor 82. Thus, the armature 62 forms a stator of the electric power generator 76 in the embodiment shown. As mentioned above, the armature 62 is part of the unit 52. The armature 62 is fixed for rotation with the hub axle 12. As shown in FIG. On the other hand, the rotor 82 is rotatably supported on the hub axle 12 to rotate about a rotation center axis A<b>1 of the electric power generator 76 . Specifically, the rotor 82 is provided on the hub body 14 to rotate with the hub body 14 . Thus, when the hub body 14 rotates with respect to the hub axle 12, the rotor 82 rotates with respect to the armature 62 for power generation. Namely, an induced electromotive force is applied to the armature 62 by the rotation of the rotor 82 and an electric current flow from the armature 62 of the electric power generator 76 is generated.

As in 4 1, armature 62 includes a winding coil 84, a bobbin 86, and a yoke 88. Here, yoke 88 includes a plurality of first yokes 88A and a plurality of second yokes 88B. The first yokes 88A are arranged in the circumferential direction of the hub axle 12 . The second yokes 88B are similarly arranged in the circumferential direction of the hub axle 12 and alternately with the first yokes 88A. The winding coil 84 is located between the first yokes 88A and the second yokes 88B in the axial direction of the hub axle 12 Alternate yokes 88B in the circumferential direction about the rotation center axis A1. The first yoke 88A and the second yoke 88B may be fixed to the bobbin 86 by an adhesive, for example.

Each of the first yokes 88A may be a laminated yoke composed of a plurality of laminated pieces, or may be a single piece. In the case of laminated yokes, the laminate pieces of the first yokes 88A are laminated together in the circumferential direction around the rotation center axis A1. The laminate pieces of the first yokes 88A are made of, for example, silicon steel sheets (specifically, non-oriented silicon steel sheets) on the surface of which an oxide film has been formed. The laminate pieces of the first yokes 88A are examples of a plate-like member.

Likewise, the second yokes 88A may be a laminated yoke composed of a plurality of laminated pieces, or may be a single piece. In the case of laminated yokes, the laminate pieces of the second yokes 88B are laminated together in the circumferential direction around the rotation center axis A1. The laminate pieces of the second yokes 88B are made of, for example, silicon steel sheets (specifically, non-oriented silicon steel sheets) on the surface of which an oxide film has been formed. The laminate pieces of the second yokes 88B are examples of a plate-like member.

The rotor 82 includes at least one magnet. Here, in the embodiment shown, the rotor 82 includes a plurality of first magnet portions 82A and a plurality of second magnet portions 82B disposed within a tubular support 82C. The tubular carrier 82C is fixedly coupled to the inside of the hub body 14 so that the magnet (rotor 82) and the hub body 14 rotate together about the hub axle 12 . The tubular support 82C has the function of a rear yoke. The back yoke is a high magnetic permeability element placed on the opposite side of the magnetized surface. By using the back yoke, a large generated magnetic field can be obtained. The tubular support 82C can be omitted. Alternatively, the hub body 14 may have the magnet (rotor 82 ) such that the hub body 14 partially forms the electric power generator 76 . The first magnetic parts 82A and the second magnetic parts 82B are arranged such that S poles and N poles of the first magnetic parts 82A and the second magnetic parts 82B are arranged alternately in the circumferential direction of the hub axle 12 . Therefore, the S poles of the first magnetic parts 82A and the S poles of the second magnetic parts 82B are not aligned with each other, and the N poles of the first magnetic parts 82A and the N poles of the second magnetic parts 82B are not aligned with each other in the axial direction of the hub axle 12 aligned.

As mentioned above, the winding coil 74A is shown as being fixed with respect to the hub axle 12 and the magnet (rotor 82) is shown as being fixed with respect to the hub body 14 . Alternatively, the winding coil 74A may be fixed with respect to the hub body 14 and the magnet (rotor 82) may be fixed with respect to the hub axle 12.

Does one refer to 8th , the armature 62 of the unit 52 has a first axle shaft receiving opening 62a. The first axle shaft receiving opening 62a is sized to receive the hub axle shaft 12 therethrough. In particular, here the axle shaft 12 has a first axle shaft section 91 which is configured to be arranged in the first axle shaft receiving opening 62a in an assembled state of the component assembly 50 . The first axle shaft portion 91 has a circular cross-sectional shape along a cross section perpendicular to the rotation center axis A1. The first axle shaft receiving hole 62a has an inner diameter equal to or slightly larger than an outer diameter of the first axle shaft portion 91 . In this way, the armature 62 is supported on the hub axle 12 .

If you refer to the 11 until 15 , the fixing plate 54 is provided on the hub axle 12 adjacent to the anchor 62 . In particular, the axle shaft 12 has a second axle shaft section 92 . The fixing plate 54 has a second axle shaft receiving hole 54a. The second axle shaft portion 92 is formed in the second axle shaft receiving hole 54a in the assembled condition of the component assembly 50 to be arranged. Fixing plate 54 is a rigid plate made of a suitable material, such as a metallic material or a reinforced plastic material. The fixing plate 54 has a circular plate shape. Here, the axle shaft 12 further includes a third axle shaft portion 93 . The third axle shaft portion 93 is disposed adjacent to the second axle shaft portion 92 . The third axle shaft portion 93 functions as an abutment for the locating plate 54 in an assembled state of the component assembly 50. In particular, the third axle shaft portion 93 has a radial dimension with respect to the central axis A1 such that the third axle shaft portion 93 does not extend axially through the second axle shaft receiving opening 54a of the locating plate 54 can pass through.

Referring to the 11 until 18 For example, when assembling the component assembly 50, the second axial end 12b of the hub axle 12 is inserted through the second axle shaft receiving opening 54a of the fixing plate 54. As soon as the fixing plate 54 rests against the third axle shaft section 93 , the second axial end 12b of the hub axle 12 is inserted through the first axle shaft receiving opening 62a of the armature 62 . Then, a washer 94 is provided on the hub axle 12 against the side of the armature 62 opposite to the third axle shaft portion 93 . Finally, a nut 95 is threaded onto the hub axle 12 to hold the armature 62 to the hub axle 12 between the locating plate 54 and the washer 94 .

As seen in Figure 18, the housing 64 of the electrical component 60 also includes a third axle shaft receiving opening 64C. The third axle shaft receiving opening 64C is sized to receive the hub axle shaft 12 therethrough. Specifically, here the axleshaft 12 includes a fourth axleshaft portion 96 configured to be disposed within the third axleshaft receiving opening 64C in an assembled state of the component assembly 50 . Here, in assembling the component assembly 50 , the electrical component 60 is slid onto the first axial end 12a of the hub axle 12 such that the hub axle 12 extends through the third axle shaft receiving opening 64C of the housing 64 of the electrical component 60 .

With reference to 19 Likewise, the anchor 62 of the unit 52 has a first connection structure 62b and the fixing plate 54 has a second connection structure 54b. The first connection structure 62b cooperates with the second connection structure 54b to prevent relative rotation between the anchor 62 and the fixation plate 54 . For example, one of the first connection structure 62b and the second connection structure 54b includes at least one protrusion, and the other of the first connection structure 62b and the second connection structure 54b includes at least one protrusion receiving space. Thus, the second connection structure 54b is an example of a connection structure configured to restrict relative rotation between the fixing plate 54 and the unit 52 of the component assembly 50 provided on the axle shaft 12 in the assembled state of the component assembly 50 .

With reference to 19 here the yoke 88 comprises the first connection structure 62b. More specifically, the first connection structure 62b is formed by radially extending end portions of the second yokes 88B. The radially extending end portions of the second yokes 88B define a plurality of projection receiving spaces or gaps 62b1 therebetween. The second connection structure 54b includes a plurality of projections 54b1. By inserting the projections 54b1 into the gaps 62b1 of the first connection structure 62b, the fixing plate 54 and the anchor 62 do not rotate with respect to each other. In other words, the second linking structure 54b engages the first linking structure 62b to limit relative pivotal movement between the fixing plate 54 and the unit 52 .

Also, referring to 20 , the electrical component 60 is coupled to the fixing plate 54 in a torque-proof manner. Here, the housing 64 includes a first connection structure 64D. Here, the first connection structure 64D includes a plurality of protrusions 64D1. The second connection structure 54b further includes a plurality of openings 54b2. By inserting the protrusions 64D1 into the openings 54b2 of the second connection structure 54b, the fixing plate 54 and the electrical component 60 do not rotate with respect to each other. In other words, the second connection structure 54b engages the first connection structure 64D to limit relative rotational movement between the fixing plate 54 and the electrical component 60 of the unit 52 .

As in the 13 and 14 As shown, the locating plate 54 is configured to engage the second axleshaft portion 92 of the hub axle 12 to prevent relative rotation between the locating plate 54 and the hub axle 12 . Since the locating plate 54 is rotationally engaged with the second axle shaft portion 92 of the hub axle 12, the electrical component 60 and the armature 62 are both rotationally fixed coupled to the hub axle 12 . In the embodiment shown, the locating plate 54 includes a projection 54c. The protrusion 54c of the fixing plate 54 is configured to engage the second axle shaft portion 92 of the hub axle 12 to prevent relative rotation between the fixing plate 54 and the hub axle 12 . Specifically, the second axle shaft portion 92 has an outer peripheral surface 92a that has a recess 92b. The protrusion 54c is formed to be disposed in the recess 92b of the axle shaft 12 to prevent the fixing plate 54 from rotating. Here recess 92b is part of axially extending recess or groove 12d. The recess 92b is spaced from the second axial end 12b of the hub axle 12 . Since the recess 92b is not provided in the first axial end 12a and the second axial end 12b of the hub axle 12, a waterproof structure can be easily formed at the first axial end 12a and the second axial end 12b of the hub axle 12. In this embodiment, in addition to complete waterproofing, the waterproof structure includes a structure that makes it difficult for water or the like to enter inside.

If you refer to the 9 until 14 , In order to allow the fixing plate 54 to be inserted onto the hub axle 12 from the second axial end 12b, the second axle shaft receiving opening 54a has a dimension in at least one direction that is larger than the diameter of the first axle shaft section 91 and the second axle shaft section 92 is. Fixing plate 54 thus includes an axle shaft receiving aperture 54a configured to receive axle shaft 12 therethrough in an assembled condition of component assembly 50 . Here's how in the 9 and 10 1, the fixing plate 54 is formed such that the second axle shaft receiving hole 54a defines a first opening portion 54a1 and a second opening portion 54a2 continuous with the first opening portion 54a1. The first opening portion 54a1 is dimensioned to allow rotation of the fixing plate 54 with respect to the second axle shaft portion 92 about the central axis A1 in a case where the second axle shaft portion 92 is located in the first opening portion 54a1 as in FIGS 11 and 12 to see. On the other hand, the second opening portion 54a2 is dimensioned to restrict rotational movement of the fixing plate 54 with respect to the second axle shaft portion 92 about the central axis A1 in a case where the second axle shaft portion 92 is located in the second opening portion 54a2, as in FIGS 13 and 14 to see. Thus, the protrusion 54c is configured to be located in the recess 92b of the axle shaft 12 to prevent the rotational movement of the fixing plate 54 in the case where the second axle shaft portion 92 is located in the second opening area 54a2.

If you now refer to the 21 until 25 For example, a different hub axle shaft 112 and a different locating plate 154 are used in conjunction with the electrical component 60 and armature 62 . The hub axle 112 includes a first axial end 112a and a second axial end 112b. The second axial end 112b is opposite to the first axial end 112a in an axial direction with respect to a center axis A1 of the hub axle 112 . The hub axle 112 further includes a first axle shaft portion 191 and a second axle shaft portion 192. The first axle shaft portion 191 is disposed between the first axial end 112a and the second axial end 112b. The second axle shaft section 192 is arranged adjacent to the first axle shaft section 191 . Thus, the second axle shaft portion 192 is disposed between the first axial end 112a and the second axial end 112b. Here, the hub axle 112 is identical to the hub axle 12, except that the second axle shaft portion 192 has an outer peripheral surface 192a that has a non-circular cross-section 192b. The first axle shaft portion 191 has a circular cross section and is adjacent to the second axle shaft portion 192 .

For example, the non-circular cross section 192b of the outer peripheral surface 192a has at least one flat contact surface 192b1. In other words, the non-circular cross-section 192b of the outer peripheral surface 192a is at least partially defined by a flat contact surface 192b1. Here, the non-circular cross section 192b of the outer peripheral surface 192a has two parallel flat contact surfaces 192b1. In other words, the non-circular cross section 192b of the outer peripheral surface 192a is at least partially defined by a pair of flat contact surfaces 192b1. Again, the locating plate 154 is identical to the locating plate 54 except that a second axle shaft receiving aperture 154a is provided to mate with the non-circular cross-section 192b of the hub axle 112 . The second axle shaft receiving opening 154a defines a first opening portion 154a1 and a second opening portion 154a2 continuous with the first opening portion 154a1. The first opening area 154a1 is dimensioned to allow rotation of the fixing plate 154 with respect to the second axle shaft portion 192 about the central axis A1 in a case where the second axle shaft portion 192 is located in the first opening area 154a1, as in FIG 24 to see. On the other hand, the second opening portion 154a2 is dimensioned to restrict a rotational movement of the fixing plate 154 with respect to the second axle shaft portion 192 about the central axis A1 in a case where the second axle shaft portion 192 is located in the second opening portion 154a2, as in FIG 25 to see. Thus, the second opening area 154a2 has a matching non-circular periphery that engages an outer peripheral surface 192a of the second axle shaft portion 192 in the case where the second axle shaft portion 192 is in the second opening area 154a2. Here, the mating non-circular perimeter of the second opening portion 154a2 has two flat edge surfaces such that the at least one flat contact surface 192b1 of the outer peripheral surface 192a of the second axle shaft portion 192 prevents relative rotation. Since the flat contact surface 192b1 is not provided in the first axial end 12a and the second axial end 12b of the hub axle 12, a waterproof structure can be easily formed at the axial ends 12a and 12b of the hub axle 12.

If you now refer to the 26 and 27 For example, a different hub axle shaft 212 and a different locating plate 254 are used in conjunction with the electrical component 60 and armature 62 . Here, the hub axle 212 is identical to the hub axle 12, except that the hub axle 212 includes a second axle shaft portion 292 having an outer peripheral surface 292a having a non-circular cross-section 292b. Here, for example, the non-circular cross section 292b of the outer peripheral surface 292a has a D-shape. Again, the locating plate 254 is identical to the locating plate 54 except that a second axle shaft receiving aperture 254a is provided to mate with the non-circular cross-section 292b of the hub axle 212 . The second axle shaft receiving opening 254a defines a first opening area 254a1 and a second opening area 254a2 continuous with the first opening area 254a1. The first opening area 254a1 is dimensioned to allow rotation of the fixing plate 254 with respect to the second axle shaft portion 292 about the central axis A1 in a case where the second axle shaft portion 292 is located in the first opening area 254a1. On the other hand, the second opening portion 254a2 is dimensioned to restrict rotational movement of the fixing plate 254 with respect to the second axle shaft portion 292 about the central axis A1 in a case where the second axle shaft portion 292 is located in the second opening portion 254a2. The second opening portion 254a2 is formed to fit with the non-circular cross section 292b (the D-shaped cross section) of the outer peripheral surface 292a. Thus, the mating non-circular perimeter of the second opening portion 254a2 has at least one flat edge surface that contacts the at least one flat contact surface of the outer peripheral surface 292a of the second axle shaft portion 292 . Although the D-shaped cross-section is formed by half the cross-section of the round shaft, the straight portion of the D-shaped cross-section can be reduced as needed and/or desired. Since the D-shaped cross section is not provided in the first axial end 12a and the second axial end 12b of the hub axle 12, a waterproof structure can be easily formed at the first axial end 12a and the second axial end 12b of the hub axle 12.
