As seen in FIG. 8 , the hub assembly 10 also includes a detected component 50 that is coupled to the sprocket support structure 30 . Specifically, the detected part 50 is fixed to the sprocket support structure 30 such that the detected part 50 and the sprocket support structure 30 rotate together about the hub axle 12 . The hub assembly 10 also includes a rotation detection sensor 52 configured to detect the detected component 50 to detect the rotation of the sprocket support structure 30 about the rotation center axis A1. The rotation detection sensor 52 is provided in the hub body 14 . In other words, the rotation detection sensor 52 is configured to detect the detected component 50 disposed on the sprocket support structure 30 . Specifically, the rotation detection sensor 52 is provided in the inner space 42 c of the housing 42 . In this way, the rotation detection sensor 52 is non-rotatably mounted to the hub body 12 . Therefore, the rotation detection sensor 52 does not rotate with the hub body 14 . The rotation detection sensor 52 is also part of the electrical assembly 38 . The rotation detection sensor 52 is electrically connected to the circuit board 44 . As seen in FIG. 7 , a rotation detection sensor 52 is provided in the hub body 14 at a location spaced radially outward from the hub axle 12 .

As in FIGS. 4 , 8 and 16 , the rotation detection sensor 52 is provided at a position axially aligned within the axial opening 28 c of the bearing spacer 28 . In this way, the bearing spacer 28 does not interfere with the rotation sensing detector 52 that detects the detected component 50 disposed on the sprocket support structure 30 . As seen in FIGS. 8 and 16 , the rotation detection sensor 52 is provided at a location separate from the circuit board 44 . In particular, the rotation detection sensor 52 is provided at a position separated from the circuit board 44 in the direction parallel to the rotation center axis A1. The rotation detection sensor 52 is electrically connected to the circuit board 44 .

In the depicted embodiment, the rotation detection sensor 52 includes a magnetic sensor, and the detected component 50 includes a magnet. Thus, the magnetic sensor detects the movement of the magnet that rotates with the sprocket support structure 30 . In other words, with this configuration, the rotation detection sensor 52 is constructed to detect the detected member 50 to detect the rotation of the sprocket support structure 30 about the rotation center axis A1. The electronic controller 48 is configured to receive the detection signal from the rotation detection sensor 52 .

Here, the magnet of the detected component 50 is a ring-shaped member having staggered S-pole segments and N-pole segments. In this way, the rotation detection sensor 52 can detect the rotation amount and rotation direction of the sprocket support structure 30 . However, the detected component 50 is not limited to the depicted annular member. For example, the detected member 50 can be formed with a single non-ring-shaped magnet or with two or more magnets spaced around the central axis of rotation A1. In the case where two or more circumferentially spaced magnets are used, a back yoke can be provided, and circumferentially spaced magnets can be provided to the back yoke. In this way, the circumferentially spaced magnets can be easily installed in the hub 10 . As used herein, the term "sensor" refers to a hardware device or device that is configured to detect a particular event, the presence or absence of an object, substance, or a change in its environment, and to emit a signal as a respond. The term "sensor" as used herein does not include humans.

The hub assembly 10 also includes at least one capacitor 54 that is electrically connected to the circuit board 44 . At least one capacitor is electrically connected to the at least one conductor. Here, the electrical component 38 contains two capacitors 54 . Capacitor 54 is an example of electrical power storage for electrical component 38 . In other words, capacitor 54 is also part of electrical component 38 . Capacitor 54 is preferably located in housing 42 of hub assembly 10 . Therefore, the capacitor 54 is non-rotatably supported on the hub axle 12 by the housing 42 .

As explained below, additional conductors electrically connect the rotation detection sensor 52 and the circuit board 44 . Here, the electrical component 38 includes a first conductor 56A and a pair of second conductors 56B. The rotation detection sensor 52 is electrically connected to the circuit board 44 through the first conductor 56A. Here, the first conductor 56A is a flexible strip conductor. The first conductor 56A can be a conductive lead. On the other hand, the circuit board 44 is electrically connected to the capacitor 54 through the second conductor 56B. The second conductor 56B extends from one of the first peripheral end portion 44a and the second peripheral end portion 44b. Here, one of the second conductors 56B extends from the first peripheral end portion 44a to electrically connect one of the capacitors 54 to the circuit board 44 . The other of the second conductors 56B extends from the second peripheral end portion 44b to electrically connect the other of the capacitors 54 to the circuit board 44 . Here, the second conductor 56B is a flexible strip conductor. The second conductor 56B can be a conductive lead. The capacitors 54 are provided in the interior space of the housing 42 at positions other than on the circuit board 44 . Capacitor 54 may be held in housing 42 using an adhesive or the like. The cover 46 is coupled to the outer casing 45 to protect the capacitor 54 disposed inside the outer casing 42 .

The circuit board 44 is electrically connected to the rotation detection sensor 52 and the capacitor 54 . In this manner, capacitor 54 provides power to circuit board 44 and other electrical components that are electrically connected to circuit board 44 . For example, capacitor 54 provides power to rotation detection sensor 52 . Also, the electronic controller 48 of the circuit board 44 is configured to control the input and output of power from the capacitor 54 .

5-8 , the hub assembly 10 also includes a one-way clutch 58 formed between the hub body 14 and the sprocket support structure 30 . The one-way clutch 58 includes a plurality of pawls 58A disposed between the hub body 14 and the sprocket support structure 30 . The one-way clutch 58 also includes a biasing member 58B that couples the pawl 58A to the sprocket support structure 30 . The one-way clutch 58 also includes a plurality of ratchet teeth 58C. The ratchet teeth 58C are provided on a fixing ring 58D fixed to the hub body 14 . Ratchet teeth 58C are provided on the inner peripheral surface of the fixing ring 58D. The retaining ring 58D is twist-locked to the hub body 14 . The fixing ring 58D is made of a hard material such as metal. The fixed ring 58D abuts the outer ring 26b of the second hub body bearing 26 in the axial direction with respect to the rotation center axis A1. The outer ring 26 b of the second hub body bearing 26 abuts against a step formed in the hub body 14 on the opposite side in the axial direction. The outer ring 26b of the second hub body bearing 26 is restricted from axial movement by the retaining ring 58D and the stepped portion formed in the hub body 14 . Biasing element 58B biases pawl 58A into engagement with ratchet teeth 58C of retaining ring 58D. Biasing element 58B pushes pawl 54 against top sprocket support structure 30 such that pawl 54 pivots toward engagement with ratchet teeth 58C of retaining ring 58D. The sealing member 58E is provided on the fixing ring 58D. The sealing member 58E is formed in an annular shape. The tongue portion of the sealing member 58E is in contact with the outer peripheral surface of the sprocket supporter 30 .

In this way, the sprocket support structure 30 is coupled to the sprocket body 14 to rotate together in the driving rotational direction D1 about the rotational center axis A1. Also, in the case where the sprocket support structure 30 is rotated in the non-driven rotational direction D2 , the ratchet teeth 58C of the sprocket support structure 18 push the pawl 58A and pivot the pawl 58A against the sprocket support structure 30 . retracted position. Therefore, the pawl support structure 30 is constructed to rotate in the non-driving rotational direction D2 about the rotational center axis A1 with respect to the hub body 14 . In this manner, the sprocket support structure 30 and the one-way clutch 58 form a flywheel typically used in bicycles. Since the basic operation of the flywheel is fairly conventional, the flywheel will not be discussed or illustrated in more detail.

As seen in FIGS. 5-8 and 10-12 , the hub assembly 10 includes a generator 60 . Therefore, the generator 60 is installed in the man-powered vehicle V. Here, the generator 60 is considered part of the electrical assembly 36 . In other words, the electrical assembly 36 includes the generator 60 .

The generator 60 is provided in the hub body 14 and is configured to generate electric power by the rotation of the hub body 14 . Rather, the generator 60 is provided to the hub body 14 between the hub axle 12 and the central portion of the hub body 14 . In the illustrated embodiment, the hub body 14 is rotatably mounted on the shaft 12 for rotation about the central axis A1 of rotation of the generator 60 . The generator 60 is configured to generate electrical power by rotation of the hub body 14 relative to the hub axle 12 . The electronic controller 48 of the circuit board 44 is electrically connected to the generator 60 for controlling the power output of the generator 60 . Thus, the power generated by the generator 60 can be stored and/or directly supplied to other components such as the rotation detection sensor 52, the rear derailleur RD, and the like.

Although the generator 60 is shown and described as part of the wheel hub assembly 10 , the generator 60 can be applied to various components of the human-powered vehicle V. Generally, the generator 60 includes a shaft, a stator, and a rotor. Accordingly, the following description of the generator 60 is not limited to being used as part of a wheel hub assembly. Rather, the following description of the generator 60 can be employed with other components of the human-powered vehicle V for generating electrical power.

In the depicted embodiment, generator 60 also includes a stator 62 and a rotor 64 . The stator 62 is not rotatable relative to the hub axle 12 . On the other hand, the rotor 64 is rotatably mounted to the hub shaft 12 so as to rotate about the rotation center axis A1 of the generator 60 . In particular, the rotor 64 is provided to the hub body 14 for rotation with the hub body 14 . Thus, as the hub body 14 rotates relative to the hub axle 12, the rotor 64 rotates relative to the stator 62 for generating electricity. That is, an induced electromotive force is generated on the stator 62 by the rotation of the rotor 64 , and current flows out of the stator 62 of the generator 60 . As seen in FIGS. 6 and 9-12, current from the stator 62 is supplied to the electrical component 38 via a pair of wires W1 and W2. The wires W1 and W2 are electrically connected to the circuit board 44 . Here, the wires W1 and W2 extend through openings in the end wall portion of the housing 42 and then through the generator 60 . As seen in FIG. 9 , the wires W1 and W2 are electrically connected to the circuit board 44 . As seen in FIGS. 11 and 12, the stator 62 has a pair of wires W3 and W4. Wire W3 is electrically connected to wire W1, and wire W4 is electrically connected to wire W2.

As seen in FIGS. 6 , 7 , 10 and 11 , the stator 62 has a first axial stator end 68A and a second axial stator end 68B, the first axial stator end 68A facing the shaft 12 relative to the central axis of rotation The first axial end 12a of A1, the second axial stator end 68B faces the second axial end 12b of the shaft 12 relative to the central axis of rotation A1. Here, the stator 62 includes an armature provided on the shaft 12 . The armature of the stator 62 includes a winding coil 62A and a bobbin 62B.

The wound coil 62A is wound on a bobbin 62B, which serves to support the wound coil 62A. The wound coil 62A is made of a conductive metal wire such as copper wire or aluminum alloy wire. The wires W3 and W4 are electrically connected to both ends of the winding coil 62A. The wire W3 is electrically connected to the wire W1 by the first electrical connector EC1. The wire W4 is electrically connected to the wire W2 by the second electrical connector EC2. In this manner, the power generated in the wire wound coil 62A is transmitted to the circuit board 44 of the electrical component 38 via the wires W1, W2, W3, and W4. The circuit board 44 then rectifies the power received from the wound coil 62A to selectively store the power in the capacitor 54 and/or selectively transmit the power out of the hub assembly 10 via the cable 40, such as Described in detail later.

The spool 62B is non-rotatably coupled to the hub axle 12 . The bobbin 62B has a cylindrical trunk portion, a first flange portion, and a second flange portion. The cylindrical trunk portion has an outer periphery on which the winding coil 62A is wound. The first flange portion and the second flange portion are formed on both the axial end portions of the cylindrical trunk portion.

In the depicted embodiment, the housing 42 is disposed between the sprocket support structure 30 and the stator 62 . The first surface 42a faces the second axial stator end 68B of the stator 62 . The first surface 42a is formed by the outer surface of the end wall portion of the housing 42 . Preferably, the housing 42 is disposed adjacent the stator 62 at the second axial stator end 68B of the stator 62 in an axial direction relative to the central axis of rotation A1.

Here, the circuit board 44 is disposed adjacent to the stator 62 at the second axial stator end 68B of the stator 62 in the axial direction relative to the rotation center axis A1. The wires W1 and W2 are connected to the circuit board 44 . In particular, the circuit board 44 has a first axially facing surface 44e facing the stator 62 and a second axially facing surface 44f facing away from the stator 62 . Here, the wires W1 and W2 are electrically connected to the second axially facing surface 44f of the circuit board 44 .

The armature of the stator 62 further includes a plurality of first yokes 62C and a plurality of second yokes 62D. The first yoke 62C is arranged in the circumferential direction of the hub shaft 12 . Likewise, the second yoke 62D is arranged in the circumferential direction of the hub shaft 12 and intersects with the first yoke 62C. The wound coil 62A is located between the first yoke 62C and the second yoke 62D in the axial direction of the hub shaft 12 . Here, the first yoke 62C and the second yoke 62D are fitted to the grooves of the bobbin 62B so that the first yoke 62C and the second yoke 62D are staggered in the circumferential direction around the rotation center axis A1. The first yoke 62C and the second yoke 62D can be attached to the bobbin 62B by, for example, an adhesive.

Each of the first yokes 62C can be a laminated yoke of a plurality of ply pieces, or can be a single piece. In the case of the laminated yoke, the ply pieces of the first yoke 62C are laminated together in the circumferential direction around the rotation center axis A1. The layered piece of the first yoke 62C is made of, for example, a silicon steel sheet (more precisely, a non-oriented silicon steel sheet), and an oxide layer has been formed on the surface of the silicon steel sheet. The ply piece of the first yoke 62C is an example of a plate-like member.

Likewise, the second yoke 62D can be a laminated yoke of a plurality of ply pieces, or can be a single piece. In the case of the laminated yoke, the ply pieces of the second yoke 62D are laminated together in the circumferential direction around the rotation center axis A1. The layered piece of the second yoke 62D is made of, for example, a silicon steel sheet (more precisely, a non-oriented silicon steel sheet), and an oxide layer has been formed on the surface of the silicon steel sheet. The ply piece of the second yoke 62D is an example of a plate-like member.

Rotor 64 includes at least one magnet. Here, in the depicted embodiment, the rotor 64 includes a plurality of first magnet members 64A and a plurality of second magnet members 64B disposed inside the tubular support 64C. The tubular support 64C is fixedly coupled to the inside of the hub body 14 so that the magnet 64 and the hub body 14 rotate together about the hub axle 12 . The tubular support 64C functions as a back yoke. The back yoke is a member with high magnetic permeability, which is arranged on the opposite side of the magnetized surface. By using the back yoke, a high generating magnetic field can be obtained. The tubular support 64C can be omitted. Alternatively, the hub body 14 can have magnets 64 such that the hub body 14 partially forms the generator 60 . The first magnet member 64A and the second magnet member 64B are arranged so that the S poles and the N poles of the first magnet member 64A and the second magnet member 64B are alternately arranged in the circumferential direction of the hub shaft 12 . Therefore, in the axial direction of the hub shaft 12, the S pole of the first magnet member 64A is not aligned with the S pole of the second magnet member 64B, and the N pole of the first magnet member 64A is not aligned with the S pole of the second magnet member 64B N pole alignment.

As mentioned above, the wound coil 62A is shown fixed relative to the hub axle 12 , and the magnet 64 is shown fixed relative to the hub body 14 . Alternatively, the wire wound coil 62A can be fixed relative to the hub body 14 and the magnet 64 can be fixed relative to the hub axle 12 .

As seen in FIGS. 6 and 10-12 , the wires W1 and W2 are electrically connected to the stator 62 at the first axial stator end 68A of the stator 62 . Wires W1 and W2 extend axially through the armature of stator 62 . More precisely, the wires W1 and W2 extend axially between the first yoke 62C and the second yoke 62D of the stator 62 . Accordingly, the wires W1 and W2 extend axially through the armature 62 at a point radially outward of the wound coil 62A.

Cable 40 is electrically connected to circuit board 44 and extends from hub body 14 . Therefore, the cable 40 is electrically connected to the generator 60 via the circuit board 44 . The other end of the cable 40 is electrically connected to another electrical component of the human-powered vehicle V, such as a rear derailleur RD, a battery pack BP, or an electrical wiring portion. In this manner, electrical cable 40 can provide power generated by hub assembly 10 to rear derailleur RD, battery pack BP, or another electrical component. The cable 40 can also be used to transmit signals from the electronic controller 48 of the circuit board 44 to the rear derailleur RD or another electrical component by using power line communication (PLC).

As seen in FIG. 5 , the cable 40 enters the hub body 10 through the opening 18b of the end cap 18 . The cable 40 then extends axially along the hub axle 12 and through the bearing spacer 28 . Cable 40 enters housing 42 of electrical assembly 38 through cover 46 . Inside the housing 42 of the electrical assembly 38 , the electrical cables 40 are electrically connected to the circuit board 44 . Preferably, as in the depicted embodiment, the electrical cable 40 is provided in the axially extending recess or groove 12d of the hub axle 12 . Thus, the groove 12d constitutes a cable receiving channel. The axially extending recess or groove 12d extends from at least the second axial end 12b to the inside of the housing 42 of the electrical assembly 38 . In this manner, the hub axle 12 includes a cable receiving channel extending axially between the electrical assembly 38 and the second axial end 12b of the hub axle 12 . Here, the groove 12d extends beyond the generator 60 from the second axial end 12b.

Referring now to Figures 14, 15, 17 and 18, the cable 40 has a first cable end 40a and a second cable end 40b. The first cable end 40a is electrically connected to the electrical assembly 38 . Here, the first cable end 40a of the cable 40 enters the first surface 42a of the housing 42 . The second cable end 40b is separated from the first cable end 40a by an intermediate section 40c of the cable 40 .

The middle section 40c of the cable 40 is wrapped at least once around the guide portion 43a to hold the middle section 40c of the cable 40 against the guide portion 43a. Although the middle section 40c is wound around the guide portion 43a only once in this embodiment, the middle section 40c can be wound around the guide portion 43a two or more times as needed and/or desired . A cable intersection 70 is formed in the intermediate section 40c of the cable 40 to limit movement of the cable 40 relative to the electrical assembly 38 . That is, here, the middle section 40c of the cable 40 extends over itself to form the cable intersection 70 on the first surface 42a of the housing 42 . Also, in the depicted embodiment, a portion of intermediate section 40c of cable 40 extends at least partially in a direction away from electrical component 38 . That is, the middle section 40c of the cable 40 extends partially from the second surface 42b in a direction away from the electrical component 38 . Since the groove 12d (cable receiving channel) extends from the second axial end 12b to the inside of the housing 42 of the electrical assembly 38, the intermediate section 40c of the electrical cable 40 can be at least partially disposed in the groove 12d. In other words, the intermediate section 40c of the cable 40 is at least partially arranged in the cable receiving channel.

Preferably, as seen in FIG. 17, the intermediate section 40c of the cable 40 includes a coiled portion 40c1, a first intersection portion 40c2, and a second intersection portion 40c3 that are wrapped around the guide portion 43a. The first intersection portion 40c2 extends beyond the second intersection portion 40c3 at the intersection point PT of the intermediate section 40c of the cable 40 .

The hub assembly 10 also includes two fixing plates 76 and 78 disposed on the hub axle 12 for non-rotatably coupling the stator 62 of the generator 60 to the hub axle 12 . Fixed plates 76 and 78 are provided on opposite ends of the generator 60 . The fixing plates 76 and 78 have a plate shape. The fixing plate 76 includes a plurality of projections 76a, and the fixing plate 78 includes a plurality of projections 78a. One of the projections 76 a of the fixing plate 76 is provided in the groove 12 d of the hub axle 12 . Likewise, one of the projections 78 a of the fixing plate 78 is provided in the groove 12 d of the hub axle 12 . The other of the projections 76a and 78a are provided in the other two axially extending grooves 12e of the hub axle 12 . By inserting the projections 76 a and 78 a into these grooves 12 d and 12 e of the hub axle 12 , the fixed plates 76 and 78 do not rotate relative to the hub axle 12 . The stator 62 of the generator 60 is not relative to the hub axle 12 by the stator 62 engaging the protrusions 76b protruding from the axially facing surface of the stationary plate 76 and the protrusion 78b protruding from the axially facing surface of the stationary plate 78 rotate. The fixing plates 76 and 78 are arranged to sandwich the stator 62 of the generator 60 from both sides in the axial direction of the stator 62 of the generator 60 . Alternatively, rotation of the fixed plates 76 and 78 relative to the hub axle 12 can also be inhibited by providing D-cuts that match the corresponding outer surfaces of the hub axle 12 . Alternatively, one of the pair of fixing plates 76 and 78 can be omitted.

Also, the housing 42 can be non-rotatably coupled to one of the stationary plates 78 for inhibiting rotation of the housing 42 relative to the hub axle 12 . For example, the keying projection 42d of the housing 42 is configured to engage the opening 78c of the fixing plate 78 which is keyed to the groove 12d of the hub axle 12 . The fixing plate 78 includes a plurality of openings 78c corresponding to the keying protrusions 42d. In this manner, the housing 42 is prevented from rotating relative to the hub axle 12 . Alternatively, the housing 42 can be attached to the bearing spacer 28 that is non-rotatably coupled to the hub axle 12 . Nut 80 is threaded onto hub axle 12 for maintaining stator 64 and housing 42 on hub axle 12 .

Referring now to FIGS. 19-21 , electrical components 138 that can be used in a wheel hub assembly are depicted. In particular, electrical component 38 of hub assembly 10 can be replaced by electrical component 138 . Here, the electrical assembly 138 includes a modified housing 142 having an outer housing 145 and a cover 146 . The electrical component 138 is identical to the electrical component 38 except that the guide portion 43a of the spacer 43 has been integrated into the electrical component 138 . Rather, the guide portion 145a is included in the electrical assembly 38 . Here, the guide portion 145 a is included in the housing 42 . The guide portion 145a is manufactured as a separate component and can be attached to the housing 142 as part of the housing 142 . The guide portion 145 a can be manufactured integrally with the outer casing 145 or the cover 146 . The outer housing 145 and the guide portion 145a can be formed as a one-piece, one-piece member. However, the guide portion 145a may be integrally formed as a part of the cover member 146 . The cover 146 and the guide portion 145a can be formed as a one-piece, one-piece member. In any case, the guide portion 145a is constructed such that the middle section 40c of the cable 40 is wrapped around the guide member 145a at least once to hold the middle section 40c of the cable 40 against the guide section 145a. The guide portion 145a forms an opening 138a for receiving the hub axle 12 . Therefore, the guide portion 145a is also constructed to receive the hub axle 12 through the guide portion 145a. As electrical assembly 138 differs from electrical assembly 38 only by having a guide portion 145a integrated therewith, electrical assembly 138 will not be discussed in greater detail. Additionally, other components of electrical assembly 138 that are identical to those of electrical assembly 38 will be given the same reference numerals.

As seen in FIG. 22 , a hub axle 212 that can be used with the hub assembly 10 is shown in place of the hub axle 12 and spacer 43 . Therefore, the cable 40 is directly wound on the outer peripheral surface of the hub shaft 212 without using the spacer 43 or the guide portion 145a. Specifically, here, the hub axle 212 is identical to the hub axle 12 , except that the diameter of the outer peripheral surface of the hub axle 212 has been increased to directly support the electrical components 38 without the use of spacers 43 . In other words, here, the guide portion 243 is included in the hub axle 212 . The guide portion 243 is constructed such that the middle section 40c of the cable 40 is wrapped around the guide section 243 at least once to hold the middle section 40c of the cable 40 against the guide section 243 . In this manner, the cable 40 is directly wound around the guide portion 243 formed on the hub axle 212 .
