[0070] <First Embodiment>

[0071] Reference Figures 1 to 14 The following describes the implementation of the transmission system 40 and the transmission device 60 for a manually driven vehicle.

[0072] A human-powered vehicle is a means of transportation that has at least one wheel and can be propelled by at least human power. Examples of human-powered vehicles include various types of bicycles such as mountain bikes, road bikes, city bikes, freight bikes, hand-cranked bicycles, and recumbent bicycles. The number of wheels a human-powered vehicle has is not limited. Human-powered vehicles also include, for example, unicycles and vehicles with two or more wheels. Human-powered vehicles are not limited to vehicles that can be propelled solely by human power. Human-powered vehicles include E-bikes, which utilize both human power and the driving force of an electric motor for propulsion. E-bikes include electric-assisted bicycles that are propelled with the assistance of an electric motor. Hereinafter, in various embodiments, human-powered vehicles will be described as bicycles.

[0073] like Figure 1 As shown, the human-powered vehicle 10 includes at least one wheel 12 and a body 14. The at least one wheel 12 includes, for example, a front wheel 12F and a rear wheel 12R. The body 14 includes a frame 16. For example, a seat 16A is mounted on the frame 16.

[0074] The human-powered vehicle 10 also includes, for example, a crank 18 that is driven by human power. The crank 18 includes, for example, crank arms 20 and crank shaft 22. The crank shaft 22 is rotatable relative to the frame 16. Pedals 24 are connected to, for example, the crank arms 20. The crank arms 20 are, for example, located at the axial ends of the crank shaft 22.

[0075] A front fork 26 is connected to the frame 16. A front wheel 12F is mounted on the front fork 26. A handlebar 28 is connected to the front fork 26 via a stem 30. A rear wheel 12R is supported on the frame 16. For example, one of the front wheel 12F and the rear wheel 12R is a drive wheel, and the other of the front wheel 12F and the rear wheel 12R is a driven wheel. In this embodiment, the rear wheel 12R is the drive wheel, and the front wheel 12F is the driven wheel. Alternatively, the front wheel 12F may be the drive wheel, and the rear wheel 12R may be the driven wheel.

[0076] The drive mechanism 32 includes, for example, a first rotating body 34 connected to the crankshaft 22. The first rotating body 34 includes, for example, a front sprocket. The first rotating body 34 may also include a pulley or a bevel gear. The crankshaft 22 may also be connected to the front sprocket via a one-way clutch.

[0077] The drive mechanism 32 may also include, for example, a second rotating body 36 and a transmission member 38. The second rotating body 36 is connected, for example, to a drive wheel. The drive mechanism 32 may also include a drive wheel. The drive wheel is configured to rotate as the second rotating body 36 rotates. The transmission member 38 is configured to transmit the rotational force of the first rotating body 34 to the second rotating body 36. The transmission member 38 may include, for example, a chain. The transmission member 38 may also include a belt or a shaft. The second rotating body 36 may include, for example, a rear sprocket. The second rotating body 36 may also include a pulley or a bevel gear. The chain is, for example, wound around the front and rear sprockets. The drive mechanism 32 may also include, for example, a driven wheel. The driven wheel is configured to rotate via the ground if the drive wheel rotates.

[0078] like Figures 1 to 3 As shown, at least a portion of a human-powered vehicle transmission system 40 is installed on the human-powered vehicle 10. The human-powered vehicle transmission system 40 includes a human-powered vehicle transmission device 60, a generator 42, and an internal gearbox 44 mounted on the drive wheels of the human-powered vehicle 10. The human-powered vehicle 10 includes the internal gearbox 44 and the generator 42. The human-powered vehicle 10 includes the transmission device 60 for controlling the internal gearbox 44.

[0079] The internal transmission 44 is integrally formed with the rear wheel hub, for example. The internal transmission 44 includes, for example, a hub axle 46 and a hub housing 48. The hub axle 46 is supported, for example, on the frame 16. The hub housing 48 is mounted to the hub axle 46 in a rotatable manner relative to the hub axle 46. The spokes of the rear wheel 12R are mounted on the hub housing 48.

[0080] The built-in transmission 44 includes, for example, a transmission body 50. The transmission body 50 includes, for example, a planetary gear mechanism. The planetary gear mechanism includes, for example, multiple sun gears disposed on the hub shaft 46. The built-in transmission 44 changes the gear ratio, for example, by changing the rotational state of each of the multiple sun gears relative to the hub shaft 46. The built-in transmission 44 changes the gear ratio, for example, by configuring one of the multiple sun gears to be immobile relative to the hub shaft 46, while allowing the other sun gears to rotate relative to the hub shaft 46, so as to select one gear ratio from the multiple gear ratios. The number of multiple gear ratios is not limited. The number of multiple gear ratios is, for example, 11, 8, 7, 6, or 5. The transmission body 50 may also include a transmission with multiple spur gears instead of a planetary gear mechanism, or may include a continuously variable transmission (CVT) with continuously changing gear ratios.

[0081] The internal transmission 44 includes a transmission control member 52 that changes the transmission ratio of the internal transmission 44. The transmission control member 52 is configured, for example, to rotate about a hub shaft 46. By rotating about the hub shaft 46, the transmission control member 52 changes the transmission ratio of the internal transmission 44. For example, the transmission control member 52 changes the rotational state relative to the hub shaft 46 for each of the multiple sun gears. A portion of the transmission control member 52 protrudes, for example, from the exterior of the hub housing 48. A portion of the transmission control member 52 protrudes, for example, from the end of the hub housing 48 along the axial direction X of the hub shaft 46.

[0082] The generator 42 is, for example, provided on the rotating component of the human-powered vehicle 10. The generator 42 is configured to generate electricity based on the rotation of the rotating component included in the drive mechanism of the human-powered vehicle 10. The rotating component includes, for example, wheels 12. The rotating component includes, for example, at least one of a front wheel 12F and a rear wheel 12R. The rotating component includes, for example, a driven wheel. The rotating component includes, for example, a front wheel 12F. The generator 42 includes, for example, a generator. The generator 42 generates alternating current at a frequency corresponding to the rotational speed of the rotating component. The generator 42 generates, for example, a generator. The electricity generated by the generator 42 has a period corresponding to the number of poles of the magnets included in the generator during one revolution of the rotating component. The number of poles of the magnets included in the generator is, for example, 2 or more and 64 or less. The number of poles of the magnets included in the generator is, for example, 32 poles. When the rotating component includes wheels 12, the generator 42 generates alternating current at a frequency corresponding to the rotational speed of the wheels 12. The generator 42 is connected to the power input section 68 of the transmission device 60 via a power line 56. For example, a terminal 56A connected to the speed changer 60 is provided on the power line 56. The power input unit 68 is configured to receive power with a waveform corresponding to the rotational speed of the rotating member. The power input unit 68 is configured to receive power with a waveform corresponding to the number of poles of the magnets included in the generator during one revolution of the rotating member. If the waveform of the power input to the power input unit 68 maintains periodic information corresponding to the number of poles of the magnets included in the generator, it can also be processed using a filter or the like.

[0083] like Figures 3 to 6 As shown, the transmission 60 includes an electric actuator 62, an output section 64, a control device 66, and an electrical input section 68. The transmission 60 also includes, for example, a drive housing 70 that houses at least a portion of the electric actuator 62 and is separate from the built-in transmission 44. The drive housing 70 is mounted, for example, on a wheel hub axle 46. The drive housing 70 is mounted on the wheel hub axle 46 in a manner that prevents it from rotating relative to the wheel hub axle 46. The drive housing 70 is, for example, separately constructed from the rear wheel hub. The drive housing 70 is, for example, mounted around the wheel hub axle 46. The drive housing 70 has, for example, a wheel hub axle mounting section 70A arranged around the wheel hub axle 46. The wheel hub axle mounting section 70A includes, for example, a through hole 70B extending axially X-orientedly in the wheel hub axle 46.

[0084] The transmission 60 is disposed adjacent to the hub housing 48 in the axial direction X of the hub shaft 46, for example. The drive housing 70 includes, for example, an inner wall portion 70C housing the transmission 44; an outer wall portion 70D opposite to the inner wall portion 70C in the axial direction X of the hub shaft 46; and a connecting portion 70E connecting the inner wall portion 70C and the outer wall portion 70D. The second rotating body 36 and the transmission member 38 are disposed, for example, between the transmission 60 and the hub housing 48 in the axial direction X of the hub shaft 46. For the drive housing 70, for example, the dimension in the axial direction X of the hub shaft 46 is smaller than the dimension in the radial direction of the hub shaft 46.

[0085] The electric actuator 62 is configured to change the gear ratio of the manually driven vehicle 10. The electric actuator 62 is configured to change the gear ratio of the internal transmission 44. The gear ratio of the manually driven vehicle 10 depends on the gear ratio of the internal transmission 44. The electric actuator 62 is configured to change the gear ratio of the manually driven vehicle 10 by changing the gear ratio of the internal transmission 44. The output unit 64 engages with the transmission control member 52 and transmits the driving force of the electric actuator 62 to the transmission control member 52. The electric actuator 62 is, for example, integrally housed in the drive housing 70. The electric actuator 62 includes, for example, a motor 62A. The motor 62A is provided in the drive housing 70, for example, with the rotation center axis of the motor output shaft 62B of the motor 62A extending in a direction orthogonal to the axial direction X of the hub shaft 46.

[0086] The speed changer 60 includes, for example, a speed reducer 72. The speed reducer 72 connects, for example, the motor 62A and the output unit 64. The speed reducer 72 includes, for example, a plurality of gears 72B. The rotational axis of the plurality of gears 72B is, for example, orthogonal to the axial direction X of the hub shaft 46. One of the plurality of gears 72B meshes with, for example, a threaded gear 72C provided on the motor output shaft 62B. Alternatively, the threaded gear 72C may be a worm gear, and the gear 72B meshing with the threaded gear 72C may be a worm wheel. In the case where the gear 72B meshing with the threaded gear 72C is a worm wheel, the threaded gear 72C and the gear 72B meshing with the threaded gear 72C constitute a worm gear.

[0087] The output portion 64 is configured such that at least a portion protrudes from the through hole 70B. The output portion 64 engages, for example, with the transmission control member 52 that protrudes to the outside of the hub housing 48. The output portion 64 engages with the transmission control member 52 in a manner that allows it to rotate integrally with the transmission control member 52. The electric actuator 62 rotates the transmission control member 52 via the reducer 72 and the output portion 64.

[0088] like Figure 12 As shown, the control device 66 includes a control unit 74. (As indicated...) Figures 7 to 9As shown, the control device 66 includes, for example, a substrate 66A on which electrical components 66X are disposed. The substrate 66A extends, for example, in a direction intersecting the hub shaft 46. The substrate 66A extends, for example, in a direction orthogonal to the axial direction X of the hub shaft 46.

[0089] Electrical component 66X includes, for example, an information processing device 76. The information processing device 76 constitutes at least a part of the control unit 74. The information processing device 76 includes, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The information processing device 76 may also be located in multiple mutually separate locations. In the case where the information processing device 76 is located in multiple mutually separate locations, the various parts of the information processing device 76 may be connected to each other via a wireless communication device in a manner enabling communication.

[0090] Figure 12 The control unit 74 shown may also include a storage unit. For example, the storage unit stores control programs and information used in control processing. The storage unit may include, for example, non-volatile memory and volatile memory. Non-volatile memory may include, for example, at least one of ROM (Read-Only Memory), EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), and flash memory. Volatile memory may include, for example, RAM (Random Access Memory). The information processing device 76 may also be configured as a semiconductor component. The storage unit may be integrally configured as a semiconductor component with the information processing device 76, or it may be integrally configured as peripheral circuitry on the information processing device 76.

[0091] The control unit 74 is configured to control the electric actuator 62. The control unit 74 includes, for example, a drive circuit 74A that controls the motor 62A. The drive circuit 74A includes, for example, an inverter that controls the power supply to the motor 62A. The information processing device 76 is configured to send control signals to the drive circuit 74A when the drive motor 62A is being driven.

[0092] like Figure 6 as well as Figure 9As shown, the power input section 68 is provided, for example, at the connection portion 70E of the drive housing 70. The power input section 68 is configured, for example, to have a terminal 56A inserted in a direction intersecting the motor output shaft 62B. The power input section 68 is also configured, for example, to have a terminal 56A inserted in a direction parallel to the axial direction X of the hub shaft 46. Power generated by the generator 42 is input to the power input section 68. The power input section 68 is configured to be detachably connected to the terminal 56A that supplies power to it. The power input to the power input section 68 is supplied to at least one of the electric actuator 62 and the control device 66.

[0093] The transmission 60 may also include, for example, a power storage unit 78. The power storage unit 78 stores power input to the power input unit 68. Electrical components 66X may include, for example, the power storage unit 78. The power storage unit 78 may include, for example, a capacitor 78A. The capacitor 78A may include, for example, a lithium-ion capacitor. The capacitor 78A may also include an electrical double-layer capacitor (EDLC), a pseudocapacitor, or a redox capacitor. The power storage unit 78 may include multiple capacitors 78A. The power storage unit 78 may also include only one capacitor 78A. The capacitor 78A may be housed inside the drive housing 70. The capacitor 78A may have a longitudinal direction. The capacitor 78A may be provided in the drive housing 70 such that its longitudinal direction extends in a direction orthogonal to the axial direction X of the hub shaft 46. The capacitor 78A may have a cylindrical shape extending in the longitudinal direction. Capacitor 78A may have, for example, a cylindrical shape extending in the longitudinal direction. Capacitor 78A may also have a polygonal prism shape extending in the longitudinal direction.

[0094] The control device 66 includes, for example, a charging control circuit 80A located between the power input section 68 and the energy storage section 78. The charging control circuit 80A controls, for example, the power input from the power input section 68 to the energy storage section 78. For example, alternating current is input to the power input section 68. The control device 66 includes, for example, a converter 80B configured to convert the alternating current input to the power input section 68 into direct current.
