DETAILED DESCRIPTION OF EMBODIMENTS

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the human-powered vehicle field (eg, the bicycle field) from this disclosure that the following descriptions of the embodiments are provided for purposes of illustration only and not for the purpose of limitation Invention as defined by the appended claims and their equivalents.

Is initially referred to 1 , a hub assembly 10 is provided on a human-powered vehicle V . In other words, the human-powered vehicle V (ie, bicycle) is shown equipped with the hub assembly 10 according to an illustrated embodiment. 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 to provide electrical power to one or more components of the human-powered vehicle V. However, the hub assembly 10 is not limited to a hub dynamo. In particular, certain aspects of hub assembly 10 may be provided that do not generate electrical energy. While hub assembly 10 is illustrated as a rear hub, certain aspects of hub assembly 10 may also be provided on a front hub. Thus, the hub assembly 10 is not limited to a rear hub.

Here, the human-powered vehicle V is an electrically assisted bicycle (e-bike). Alternatively, the human-powered vehicle V may be a racing bike, a city bike, a cargo bike, and a recumbent bike, or another type of off-road bike such as a cyclocross bike. As in 1 1, the human-driven vehicle 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 to 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 human-powered vehicle V further includes a powertrain DT and an electric drive unit DU operatively coupled to the powertrain 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 is operable to assist propulsion of the human-powered vehicle 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 human-powered vehicle V. As shown in FIG. The main battery pack BP can supply electric power to other vehicle components such as the rear derailleur (or 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 human-powered vehicle V further includes a cycle computer SC. Here is the cycle computer SC on the front frame body FB mounted. Alternatively, the cycle computer SC may be provided on the handlebar H. The cycle computer SC notifies the driver of various travel and/or operating states of the human-powered vehicle 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 human-powered vehicle V.

Here, the human-propelled vehicle V further includes a derailleur RD fixed to the rear frame body RB for shifting 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 rear derailleur (i.e., 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 driver of the human-powered vehicle V manually operates a gearshift operating device or shifting device SL. The rear derailleur RD may also be actuated automatically based on travel conditions and/or operating conditions of the human-powered vehicle V. The human-powered vehicle 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 state, as discussed herein.

The structure of the hub assembly 10 will now be described with particular reference to FIG 2 until 8th 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 rotational 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 5 until 7 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, the hub axle 12 is provided with a first end piece or end cap 16 and a second end piece or end cap 18 . The first end cap 16 is attached to the first axial end 12a (left side in Figs 2 until 8th ) of the hub axle 12 is assembled, and the second end cap 18 is fitted to the second axial end 12b (right side in Figs 2 until 8th ) of the hub axle shaft 12 mounted. For example, the first end cap 16 is bolted to the first axial end 12a of the hub axle 12, and the second end cap 18 is fixed to the second axial end 12b of the hub axle 12 by a locating bolt 20 threaded into the axial bore 12c of the hub axle 12. In this way, the first 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. The rotation restricting part 18a 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 5 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 cam 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 cam 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 change the distance 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 , 3 and 4 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 having 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 5 and 6 1, the hub assembly 10 further includes a first hub shell bearing 24. The first hub shell bearing 24 supports the hub shell 14 for rotation. Preferably, the hub assembly 10 further includes a second hub body bearing 26 that rotatably supports one end of the hub body 14 . The first hub bearing 24 rotatably supports the other end of the hub body 14 with respect to the rotation center axis A1. The first hub bearing 24 includes a first inner race 24a, a first outer race 24b, and a plurality of first roller members 24c. The first roller elements 24c are arranged between the first inner ring 24a and the first outer ring 24b. The second hub bearing 26 includes a second inner race 26a, a second outer race 26b, and a plurality of second roller members 26c. The second roller elements 26c are arranged between the second inner ring 26a and the second outer ring 26b. The first hub bearing 24 and the second hub bearing 26 are radial ball bearings. Radial ball bearings support a force in the direction perpendicular to the axis. Further, a radial roller bearing can be selected instead of the radial ball bearing. Radial roller bearings include cylindrical roller bearings and needle roller bearings.

Here, the hub assembly 10 further includes a bearing spacer 28. The bearing spacer 28 is provided on the hub axle 12 and supports the hub body 14 via the second hub bearing 26. The bearing spacer 28 supports the second hub bearing 26. The bearing spacer 28 has an inner peripheral end 28a that of the hub axle 12, and an outer peripheral end 28b spaced radially outward from the inner peripheral end 28 in a radial direction with respect to the rotation center axis A1. The second hub bearing 26 is disposed at the outer peripheral end 28b of the bearing spacer 28 and rotatably supports the hub body 14 . The bearing spacer 28 is rotationally fixed with respect to the hub axle 12 . As in 4 In particular, the inner peripheral end 28a defines a non-circular opening 28a1 that mates with a non-circular portion of the hub axle 12 to rotationally couple the bearing spacer 28 with respect to the hub axle 12 . The axial position of the bearing spacer 28 relative to the hub axle 12 can be determined by sandwiching it between a step provided on the hub axle 12 and a nut screwed to the hub axle 12 . Here, the bearing spacer 28 includes an axial opening 28c.

Here, the hub assembly 10 further includes a gear support structure 30. In the embodiment shown, the gear support structure 30 supports the rear gears CS as shown in FIG 2 to see. The gear support structure 30 is arranged rotatably about the rotation center axis A1 to transmit a driving force to the hub body 14 when rotating in a drive rotation direction about the rotation center axis A1. As discussed below, the gear support structure 30 transmits no driving force to the hub body 14 when 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 center axis of rotation of the gear support structure 30 is arranged concentrically with the center axis A1 of rotation of the hub assembly 10 .

While the gear support structure 30 is configured to non-rotatably support the rear gears CS, the gear support structure 30 is not limited to the illustrated embodiment. Alternatively, one or more of the gears CS may be integrally formed with the gear support structure 30 . In any case, the gear support structure 30 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 first gear support bearing 32 and a second gear support bearing 34. The first gear support bearing 32 rotatably supports a first end 30a of the gear support structure 30. As shown in FIG. The second gear support bearing 34 rotatably supports a second end 30b of the gear support structure 30 . The first gear support bearing 32 and the second gear support bearing 34 have outside diameters that are smaller than the outer peripheral end 28 b of the bearing spacer 28 . The inside diameter of the first gear support bearing 32 is larger than the inner diameter of the second gear support bearing 34. Thus, the first gear support bearing 32 and the second gear support bearing 34 can be assembled to the hub axle 12 from the second axial end 12b of the hub axle 12. The first gear support bearing 32 includes a first inner ring 32a, a first outer ring 32b and a plurality of first roller elements 32c. The first roller elements 32c are arranged between the first inner ring 32a and the first outer ring 32b. The second gear support bearing 34 includes a second inner ring 34a, a second outer ring 34b and a plurality of second roller elements 34c. The second roller elements 34c are arranged between the second inner ring 34a and the second outer ring 34b. Here, the first gear support bearing 32 and the second gear support bearing 34 are radial ball bearings. Radial ball bearings support a force in the direction perpendicular to the axis. Further, a radial roller bearing can be selected instead of the radial ball bearing. Radial roller bearings include cylindrical roller bearings and needle roller bearings. A tubular spacer 35 is disposed between the first gear support bearing 32 and the second gear support bearing 34 .

As in the 5 until 7 1, the hub assembly 10 further includes an electrical assembly 36. Simply put, the electrical assembly 36 is an example of a component assembly of the present disclosure. However, the component arrangement of the present disclosure is not limited to the electrical assembly 36 of the present disclosure. The arrangement of the component assembly of the present disclosure may be applied to other electrical assemblies or non-electrical assemblies. For example, the component assembly of the present disclosure may be adapted to an electric motor or actuator, an electric derailleur/rear derailleur, an electric height adjustable seat post, an electric suspension adjustment mechanism, and so forth. In any event, the component assembly is intended for a human-powered vehicle. Here, the hub assembly 10 includes the component assembly.

The electrical assembly 36 (i.e., component assembly) includes an electrical component 38. Thus, the hub assembly 10 further includes the electrical component 38. The electrical component 38 is rotationally fixed relative to the hub axle 12, and the electrical cable 40 is an electrical cable that is electrically connected to the electrical component. While electrical component 38 is part of hub assembly 10 in the embodiment shown, electrical component 38 may be used with other components and/or assemblies of the human-powered vehicle. The electrical component 38 has an opening 38a for receiving the hub axle 12 therethrough. Thus, the electrical component 38 is carried on the hub axle 12 . As will be explained later, the electrical component 38 is arranged on the hub axle 12 in a rotationally fixed manner.

Here, the electrical component 38 includes a housing 42. The housing 42 is configured to define the opening 38a of the component 38 that receives the hub axle 12. As shown in FIG. However, the electric component 38 further includes a spacer 43 disposed in the opening 38a between the hub axle 12 and the electric component 38 in the radial direction with respect to the rotation center axis A1. In other words, the hub assembly 10 further includes the spacer 43 interposed between the hub axle 12 and the electric component 38 in the radial direction with respect to the rotation center axis A1. The spacer 43 is a tubular support having a cylindrical guide portion 43a and an annular abutment portion 43b. As will be described later, the housing 42 is provided on the hub axle 12 in a non-rotatable manner. Thus, the housing 42 is fixed with respect to the hub axle 12.

The electrical component 38 also includes an electrical circuit board 44 . The electrical component 38 is disposed within the hub body 14 . The electric circuit board 44 is thus arranged in the housing 42 . The electric cable 40 is electrically connected to the electric circuit board 44 . More specifically, the first end 40a of the electric wire 40 is electrically connected to the electric circuit board 44 . In the embodiment shown, the electrical circuit board 44 is disposed within the housing 42 which is fixed against rotation with respect to the hub axle 12 . The housing 42 is configured to house the electrical circuit board 44 as well as other parts and elements.

In the embodiment shown, the housing 42 includes a housing body 45 and a cover 46. The cover 46 is attached to the housing body 45 to enclose the electrical circuit board 44 in the housing 42. As shown in FIG. Here, the lid 46 is bonded to the case body 45 by adhesive or welding. However, the lid 46 may be fixed to the case body 45 by a threaded fastener, rivets, etc. Preferably, the housing body 45 and the lid 46 are rigid members made of a suitable material. For example, the case body 45 and the lid 46 are made of a resin material. For example, can the case body 45 and the lid 46 may each be injection molded members. In the embodiment shown, bearing spacer 28 is fixedly secured to housing 42 by a plurality of threaded fasteners 47 . Threaded fasteners 47 thread into cover 46 of housing 42 .

As in the 7 and 8th As can be seen, the cover 46 is coupled to the case body 45 to protect the electrical circuit board 44 and other parts contained in the case 42 . The lid 46 covers the inner space 42c of the housing body 45. Thus, at least the housing 42, the electric circuit board 44 and the capacitor 54 can be considered as constituting an electric unit arranged in the hub body 14. In this way, the electrical circuit board 44 is rotationally fixed with respect to the hub axle 12 . The electric circuit board 44 is arranged perpendicularly to the rotation center axis A1. Electrical circuit board 44 is part of electrical component 38.

Here, the electric circuit board 44 has a first peripheral end portion 44a and a second peripheral end portion 44b. The electric circuit board 44 also has an inner arcuate edge 44c and an outer arcuate edge 44d with respect to the rotation center axis A1. The electrical circuit board 44 also includes an electronic control device 48 which is provided on the electrical circuit board 44 . The electronic control device 48 is designed to receive a detection signal from the rotation detection sensor 52 . The electronic control device 48 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 44 preferably further includes a data storage device (memory) provided on the electric circuit board 44 . 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. The data storage device includes any computer storage device or non-transitory computer-readable medium with the sole exception of a transient, spreading signal. The data storage device 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).

As in 8th 1, the hub assembly 10 further includes a sensed member 50 coupled to the gear support structure 30. As shown in FIG. Specifically, the detected part 50 is fixed to the gear support structure 30 so that the detected part 50 and the gear support structure 30 rotate together around the hub axle 12 . The hub assembly 10 further includes a rotation detection sensor 52 configured to detect the detected part 50 to detect rotation of the gear support structure 30 about the rotation center axis A1. The rotation detection sensor 52 is arranged in the hub body 14 . In other words, the rotation detection sensor 52 is configured to detect the detected part 50 provided on the gear support structure 30 . Specifically, the rotation detection sensor 52 is provided in the inner space 42c of the housing 42 . In this way, the rotation detection sensor 52 is non-rotatably mounted on the hub axle 12 . Thus, the rotation detection sensor 52 does not rotate with the hub body 14. The rotation detection sensor 52 is also part of the electrical component 38. The rotation detection sensor 52 is electrically connected to the electrical circuit board 44. FIG. As in 8th As shown, the rotation detection sensor 52 is disposed within the hub body 14 at a location spaced radially outward from the hub body 12 .

As in the 4 and 8th 1, the rotation detection sensor 52 is disposed at a position axially aligned with the axial opening 28c of the bearing spacer 28. As shown in FIG. In this way, the bearing spacer 28 does not interfere with the rotation detection sensor 52 that detects the detected part 50 provided on the gear support structure 30 . As in 8th As can be seen, the rotation detection sensor 52 is arranged at a position separated from the electric circuit board 44 . Specifically, the rotation detection sensor 52 is arranged at a position separated from the electric circuit board 44 in a direction parallel to the rotation center axis A1 direction is separated. The rotation detection sensor 52 is electrically connected to the electric circuit board 44 .

In the shown embodiment, the rotation detection sensor 52 includes a magnetic sensor and the detected part 50 includes a magnet. Thus, the magnetic sensor detects movement of the magnet rotating together with the gear support structure 30 . In other words, with this arrangement, the rotation detection sensor 52 is configured to detect the detected part 50 to detect rotation of the gear support structure 30 around the rotation center axis A1. The electronic control device 48 is designed to receive a detection signal from the rotation detection sensor 52 .

Here's how in 8th As can be seen, the magnet of the detected part 50 is an annular element with alternating S-pole sections and N-pole sections. In this way, the rotation detection sensor 52 can detect a rotation amount and a rotation direction of the gear support structure 30 . However, the detected part 50 is not limited to the illustrated annular member. For example, the detected part 50 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 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.

As in the 12 and 14 As shown, the hub assembly 10 further includes at least one capacitor 54 electrically connected to the electrical circuit board 44 . The at least one capacitor is electrically connected to the at least one conductor. Here, the electrical component 38 includes two capacitors 54. The capacitors 54 are examples of an electrical energy storage device of the electrical component 38. In other words, the capacitor 54 is also a part of the electrical component 38. The capacitors 54 are preferably in the housing 42 of the hub assembly 10 arranged. Thus, the capacitors 54 are rotatably supported on the hub axle 12 by the housing 42 .

As described below, an additional conductor connects the rotation detection sensor 52 and the electrical circuit board 44. Also 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 electric circuit board 44 through the first conductor 56A. Here the first conductor 56A is a flexible ribbon conductor. The first conductor 56A may be an electrically conductive line. On the other hand, the electric circuit board 44 is electrically connected to the capacitors 54 through the second conductors 56B. The second conductors 56B extend 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 electric circuit board 44. As shown in FIG. 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 electric circuit board 44. FIG. Here the second conductors 56B are flexible ribbon conductors. The second conductors 56B can be an electrically conductive line. The capacitor 54 is provided in the interior of the case 42 at a position different from that on the electronic circuit board 44 . The capacitor 54 can be held in the housing 42 with an adhesive or the like. The cover 46 is coupled to the case body 45 to protect the capacitors 54 disposed within the case 42 .

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

As in the 5 until 8th 1, the hub assembly 10 further includes a one-way clutch 58 formed between the hub body 14 and the gear support structure 30. As shown in FIG. The one-way clutch 58 includes a plurality of pawls 58A disposed between the hub body 14 and the gear support structure 30 . The one-way clutch 58 further includes a front tension member 58B coupling pawls 58A to gear support structure 30. The one-way clutch 58 further includes a plurality of ratchet teeth 58C. The ratchet teeth 58C are provided on a fixing ring 58D fixed to the hub body 14 . The ratchet teeth 58C are provided on the inner peripheral surface of the fixing ring 58D. The fixing ring 58D is screwed to the hub body 14. The fixing ring 58D is made of a hard material such as metal. The fixing ring 58D abuts against the outer ring 26b of the second hub bearing 26 in the axial direction with respect to the rotation center axis A1. The opposite side of the outer ring 26 b of the second hub bearing 26 in the axial direction abuts against a step formed in the hub body 14 . The outer ring 26b of the second hub bearing 26 is restricted in axial movement by the locating ring 58D and the steps formed on the hub body 14. As shown in FIG. The biasing member 58B biases the pawls 58A into engagement with the ratchet teeth 58C of the locator ring 58D. The biasing member 58B urges the pawls 58A against the gear support structure 30 such that the pawls 58B pivot toward engagement with the ratchet teeth 58C of the locator ring 58D. A sealing member 58E is provided on the fixing ring 58D. The seal member 58E is formed in a ring shape. The tongue portion of the seal member 58E is in contact with the outer peripheral surface of the pinion carrier 30 .

In this way, the gear support structure 30 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 structure 30 is rotated in the non-drive rotational direction D2, the ratchet teeth 58C of the gear support structure 18 also press against the pawls 58A and pivot the pawls 58A to a retracted position against the gear support structure 30. Thus, the gear support structure 30 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 support structure 30 and the one-way clutch 58 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 5 until 10 1, the hub assembly 10 includes an electrical power generating device 60. Here, the electrical power generating device 60 is considered part of the electrical subassembly 36. FIG. In other words, the electrical assembly 36 includes the electrical energy generating device 60. The electrical cable 40 is electrically connected to the electrical energy generating device 60 via the electrical circuit board 44. In this way, the electric cable 40 can supply electric power generated by the hub assembly 10 to the rear derailleur RD, the battery pack BP, or another electric component. The electrical cable 40 may also be used to transmit signals from the electronic controller 48 of the electrical circuit board 44 to the rear derailleur RD or other electrical component via power line communication (PLC).

The electric power generator 60 is provided on the hub body 14 and is configured to generate electric power by rotating the hub body 14 . More specifically, the electric power generator 60 is provided on the hub body 14 between the hub axle 12 and a central portion of the hub body 14 . In the illustrated embodiment, the hub body 14 is rotatably supported on the hub axle 12 to rotate about the rotation center axis A<b>1 of the electric power generation device 60 . The electrical energy generating device 60 is designed to generate electrical energy by rotating the hub body 14 relative to the hub axle 12 . The electronic controller 48 of the electric circuit board 44 is electrically connected to the electric power generation device 60 to control the electric power output of the electric power generation device 60 . Thus, the electrical energy generated by the electrical energy generating device 60 can be stored and/or supplied directly to other components, such as the rotation detection sensor 52, the rear derailleur RD, etc.

Although the electric power generating device 60 is illustrated and described as part of the hub assembly 10, the electric power generating device 60 may be attached to a different part of the human-powered vehicle V. In general, the electric power generation device 60 includes an axle shaft, a stator, and a rotor. Thus, the following description of the electrical energy generating device 60 is not limited to use as part of the hub assembly. Rather, the following description of the electric power generation device 60 can be adapted to other parts of the human-powered vehicle V for generating electricity.

In the embodiment shown, the electrical power generation device 60 further includes a stator 62 and a rotor 64. The stator 62 is relative to the hub axle 12 non-rotatable. On the other hand, the rotor 64 is rotatably supported on the hub axle 12 to rotate about a rotation center axis A<b>1 of the electric power generation device 60 . Specifically, the rotor 64 is provided on the hub body 14 to rotate with the hub body 14 . Thus, when the hub body 14 rotates relative to the hub axle 12, the rotor 64 rotates relative to the stator 62 to generate power. Namely, an induced electromotive force is generated on the stator 62 by the rotation of the rotor 64 and an electric current flow from the stator 62 of the electric power generation device 60 .

As in the 6 , 9 and 10 1, electrical power is supplied from the stator 62 to the electrical component 38 via a pair of electrical cables 66 and 68. FIG. Electrical cables 66 and 68 are electrically connected to electrical circuit board 44 . Here, the electrical wires 66 and 68 are electrically connected to the side of the electrical circuit board 44 that is remote from the stator 62 . Also, the electrical cables 66 and 68 pass through openings in an end wall portion of the housing 42 and then pass through the electrical power generating device 60. As in FIG 14 As can be seen, the electrical cables 66 and 68 are electrically connected to the electrical circuit board 44 . As in the 9 and 10 As can be seen, the stator 62 has a pair of electrical cables 70 and 72 . Electrical cable 70 is electrically connected to electrical cable 66 and electrical cable 72 is electrically connected to electrical cable 68 .

In principle, the component assembly comprises an element and a wire rod. As mentioned above, in the embodiment shown, the electrical assembly 36 is an example of the component arrangement. Where the component assembly is the electrical assembly 36, the element of the component assembly corresponds to the housing 42, and a wire rod of the component assembly corresponds to each of the electrical cables 66 and 68. As mentioned above, the housing 42 (the element) is rotationally coupled to the hub axle 12 . Where the assembly of components is the electrical assembly 36 , the element is rotationally coupled to the hub axle 12 . In the embodiment shown, the housing 42 (element) is positioned between the gear support structure 30 and the stator 62 . Preferably, the case 42 (the member) is disposed adjacent to the stator 62 in the axial direction with respect to the rotation center axis A1.

Referring to the 15 until 18 An exemplary process for suppressing axial movement of the electrical cables 66 and 68 (ie, wire rods) with respect to the housing 42 (element) will now be discussed. The element basically comprises a wall having a first surface, a second surface opposite the first surface, and an opening. Where the component assembly is the electrical assembly 36, the housing body 45 of the housing 42 (component assembly member) includes a wall 73 having a first surface 73a, a second surface 73b opposite the first surface 73a, and an opening 73c. Aperture 73c is sized to receive electrical cord 66 as shown in FIGS 15 and 16 to see. Here, the wall 73 further includes a further opening 73d sized to receive the electrical cable 68 as shown in FIGS 15 and 16 to see. Thus, where the assembly of components is the electrical assembly 36, the housing 42 includes the member having the wall 73 with openings 73c and 73d, and the wire rod is the electrical cable 66 or 68 having a first end connected to the electrical Component 38 is electrically connected.

Here the electrical cables 66 and 68 pass through the openings 73c and 73d in the wall 73, as in FIGS 15 and 16 to see. Thus, the wire rod (the electric wire 66 or 68) includes a first portion located on the first surface 73a side of the wall 73 and a second portion located on the second surface 73b side of the wall 73 . Where the assembly of components is the electrical assembly 36, the electrical cable 66 (the wire rod) includes a first portion 66a and a second portion 66b, and the electrical cable 68 (the wire rod) includes a first portion 68a and a second portion 68b. The first portion 66a and the first portion 68a are located on the first surface 73a side of the wall 73 in a state where the electric wires 66 and 68 are arranged on the case 42 (member). The second portion 66b and the second portion 68b are located on the second surface 73b side of the wall 73 in a state where the electric wires 66 and 68 are arranged on the case 42 (member). Here, the second portion 66b of the wire rod (electrical cord 66) includes an insulated outer sheath 66b1. Also here, the second portion 68b of the wire rod (electrical cable 68) includes an insulated outer sheath 68b1. While first portion 66a and first portion 68a are not isolated in the embodiment shown, first portion 66a and first portion 68a may be isolated as needed and/or desired. However, if the electrical wires 66 and 68 are insulated, then one of the openings 73c and 73d can be omitted so that both of the electrical Cables 66 and 68 can pass through a single opening in wall 73.

For the electrical cable 66 (the wire rod) includes, as shown in FIGS 17 and 18 1, first portion 66a includes an abutment portion 66a1 that contacts first surface 73a adjacent opening 73c in wall 73 to permit axial movement of wire rod first portion 66a through opening 73c in wall 73 with respect to an axial direction with respect to a central axis of the opening 73c in the wall 73. Preferably, the abutting portion 66a1 is a deformed portion of the wire rod (the electric wire 66). In one embodiment, as shown in FIGS 17 and 18 As can be seen, the abutment portion 66a1 has a coil shape. However, the section 66a1 can be trained to other wise, such as by attaching a system that is one of the electrical cable 66 separate component, on the first section 66a of the electrical cable 66. As in the 19 and 20 As can be seen, the abutment section 66a1 alternatively comprises at least one crank shape.

For electrical cable 68 (the wire rod), first portion 68a includes an abutment portion 68a1 that contacts first surface 73a adjacent opening 73d in wall 73 to permit axial movement of wire rod first portion 68a through opening 73d in the wall 73 with respect to an axial direction with respect to a central axis of the opening 73d in the wall 73. Preferably, the abutting portion 68a1 is a deformed portion of the wire rod (the electric wire 68). In one embodiment, as shown in FIGS 17 and 18 As can be seen, the abutment portion 68a1 has a coil shape. However, the 68A1 section can be trained to other wise, such as by attaching a investment part that is one of the electrical cable 68 separate component, on the first section 68a of the electrical cable 68. As in the 19 and 20 As can be seen, the abutment section 68a1 alternatively comprises at least one crank shape.

In the illustrated embodiment, as shown in FIGS 18 and 20 1, the assembly of components further includes a fastener material 74 that couples abutment portions 66a1 and 68a1 to first surface 73a of wall 73. Preferably, the fixing material 74 comprises a sealing material that at least partially seals the openings 73c and 73d in the wall 73. Here, the fixing material 74 includes a resin material that at least partially covers the first surface 73a of the wall 73 and the abutment portion 66a1. The fixing material 74 is preferably applied in a liquid state to the case body 45 of the case 42 (component assembly member) to cover the abutment portion 66a1, the abutment portion 68a1 and the first surface 73a of the wall 73 adjacent to the openings 73c and 73d. Then, the fixing material 74 hardens with time to fix the abutment portion 66a1 and the abutment portion 68a1 to the first surface 73a of the wall 73. FIG. The fixing material 74 prevents the electric wire 66 and 68 from moving relative to the wall 73 in the longitudinal direction of the electric wire 66 and 67 . Further, the fixing material 74 prevents the electric wire 66 and 68 from rotating around the longitudinal direction of the electric wire 66 and 68 by fixing the abutting portions 66a1 and 68a1.

As in the 15 until 20 1, in the illustrated embodiment, the first surface 73a includes a border portion 75 configured to surround the openings 73c and 73d, and the fixing material 74 is placed in the border portion 75. FIG. In this way, the fixing material 74 is confined within the area surrounded by the confining portion 75 . Here, the enclosing portion 75 is an annular wall extending in a perpendicular direction with respect to the wall 73 to form a fixing material accommodating cavity. In the embodiment shown, the annular wall extends from the first surface 73a of the wall 73. Here a protrusion 75a is provided in the fixative material receiving cavity defined by the perimeter portion 75. FIG. When the fixing material 74 is applied to the case body 45 of the case 42 in a liquid state, the protrusion 75a is at least partially covered by the fixing material 74 . In the shown embodiment, the projection 75a is provided between the abutment portion 66a1 and the abutment portion 68a1. In this way, the fixing material 74 is fixed to the case body 45 of the case 42 more firmly. Here, the projection 75a is a single planar wall extending in a direction perpendicular to the wall 73. As shown in FIG. The projection extends from the first surface 73a of the wall 73. However, the projection 75a can have a variety of shapes. Additional protrusions may also be provided in the fixative material receiving cavity defined by the perimeter portion 75 .

As in the 6 , 7 and 10 and 11 As shown, the stator 62 includes an armature disposed on the axle shaft 12 . The armature of the stator 62 includes a winding coil 62a and a bobbin 62B. The winding coil 62A is wound on the bobbin 62B for supporting the winding coil 62A. The winding coil 62A is made of conductive metal wire mate rial, such as a copper wire or an aluminum alloy wire. The electric wires 70 and 72 are electrically connected to both ends of the winding coil 62A. The electrical wire 70 is electrically connected to the electrical wire 66 by a first electrical connector EC1. The electrical cable 72 is electrically connected to the electrical cable 68 by a second electrical connector EC2. In this way, electrical energy generated in the winding coil 62A is transmitted to the electrical circuit board 44 of the electrical component 38 via the electrical cables 66, 68, 70 and 72. The electrical circuit board 44 then regulates the electrical energy received from the winding coil 62A to selectively store the electrical energy in the capacitors 54 and/or transmit the electrical energy external to the hub assembly 10 via the electrical cable 40, as below explained.

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

The armature of the stator 62 further includes a plurality of first yokes 62C and a plurality of second yokes 62D. The first yokes 62C are arranged in the circumferential direction of the hub axle 12 . The second yokes 62D are similarly arranged in the circumferential direction of the hub axle 12 and alternate with the first yokes 62C. The winding coil 62A is located between the first yokes 62C and the second yokes 62D in the axial direction of the hub axle 12 Alternate yokes 62D in the circumferential direction about the rotation center axis A1. The first yoke 62C and the second yoke 62D may be fixed to the bobbin 62B by an adhesive, for example.

Each of the first yokes 62C may be a laminated yoke composed of a plurality of pieces of sheet metal, or may be a single piece. In the case of lamination yokes, the lamination pieces of the first yokes 62C are laminated together in the circumferential direction around the rotation center axis A1. The sheet pieces of the first yokes 62C 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 sheet pieces of the first yokes 62C are examples of a plate-like member.

Likewise, the second yokes 62D may be a laminated yoke made up of a plurality of pieces of sheet metal, or may be a single piece. In the case of laminated yokes, the laminated pieces of the second yokes 62D are laminated together in the circumferential direction around the rotation center axis A1. The sheet pieces of the second yokes 62D 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 sheet pieces of the second yokes 62D are examples of a plate-like member.

The rotor 64 includes at least one magnet. Here, in the embodiment shown, the rotor 64 includes a plurality of first magnet portions 64A and a plurality of second magnet portions 64B disposed within a tubular support 64C. The tubular carrier 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 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 64C can be omitted. Alternatively, the hub body 14 may have the magnet (rotor 64 ) such that the hub body 14 partially forms the electric power generation device 60 . The first magnetic parts 64A and the second magnetic parts 64B are arranged such that S poles and N poles of the first magnetic parts 64A and the second magnetic parts 64B are arranged alternately in the circumferential direction of the hub axle 12 . Therefore, the S poles of the first magnetic parts 64A and the S poles of the second magnetic parts 64B are not aligned with each other, and the N poles of the first magnetic parts 64A and the N poles of the second magnetic parts 64B are not aligned with each other in the axial direction of the hub axle 12 aligned.

As mentioned above, the winding coil 62A is shown as being fixed with respect to the hub axle 12 and the magnet (rotor 64) is shown as being fixed with respect to the hub body 14. Alternatively, the winding coil 62A may be fixed with respect to the hub body 14 and the magnet 64 may be fixed with respect to the hub axle 12 .

As in the 6 and 10 until 12 As can be seen, the electrical cables 66 and 68 are electrically connected to the stator 62 . The electrical cables 66 and 68 run axially through the armature of the stator 62. Specifically, the electrical cables 66 and 68 run axially between the first yokes 62C and the second yokes 62D of the stator 62. The electrical cables 66 and 68 thus run axially through the armature 62 at a point radially outward of the winding coil 62A.

Optionally, one of the pair of fixing plates 76 and 78 can be omitted.

Also, the housing 42 may be rotationally coupled to one of the locating plates 78 to restrain rotation of the housing 42 relative to the hub axle 12 . As in the 6 and 7 For example, as shown, a plurality of fitting lugs 79 of the housing 42 are formed to engage with openings 78c of the fixing plate 78 fitted into the groove 12d of the hub axle 12. As shown in FIG. The fixing plate 78 includes a plurality of openings 78c corresponding to the fitting bosses 79. As shown in FIG. In this way, the housing 42 is prevented from rotating relative to the hub axle 12 . Alternatively, the housing 42 may be attached to the bearing spacer 28 which is rotationally coupled to the hub axle 12 . A nut 80 threads onto the hub axle 12 to hold the stator 62 and housing 42 to the hub axle 12 .
