DETAILED DESCRIPTION OF THE INVENTION
[0013] {First embodiment} The saddle-ride type vehicle, the motor support attachment, and the method for manufacturing the saddle-ride type vehicle according to the first embodiment will be described below.
[0014] In this embodiment, an example will be described in which the saddle-ride type vehicle is a motorcycle. A saddle-ride type vehicle is a vehicle that is driven by a driver astride a seat. The saddle-ride type vehicle may be a scooter-type vehicle in which the driver straddles a seat and places their feet on steps. The saddle-ride type vehicle may also be an ATV (All Terrain Vehicle).
[0015] 1 is a schematic side view showing a saddle-ride type vehicle 10. The overall configuration of the saddle-ride type vehicle 10 will be described.
[0016] The saddle-ride type vehicle 10 includes a main frame 30, a front wheel 12, a rear wheel 14, and a handle device 20.
[0017] In the following description, when referring to up and down, front and rear, and left and right, each direction is defined as follows. First, the side where the front wheels 12 and rear wheels 14 of the saddle-ride type vehicle 10 come into contact with the road surface is the bottom, and the opposite side is the top. Also, the traveling direction when the saddle-ride type vehicle 10 is traveling is the front, and the opposite side is the rear. Furthermore, when a driver is riding on the saddle-ride type vehicle 10 facing forward, the left and right sides of the saddle-ride type vehicle 10 are based on the driver. In this embodiment, the left and right direction may be described as the vehicle width direction.
[0018] A front wheel 12 is rotatably supported on the front side of the main frame 30 via a front fork 17. A rear wheel 14 is rotatably supported on the rear side of the main frame 30 via a swing arm 28. A handle device 20 is supported on the front side of the main frame 30.
[0019] The vehicle 10 can travel on a road surface by rotating the front wheels 12 and rear wheels 14 while the wheels are in contact with the road surface. When the steering device 20 is rotated, the front wheels 12 rotate around the steering axis. This allows the vehicle 10 to change its direction of travel.
[0020] The saddle-ride type vehicle 10 also includes a motor unit 50. The motor unit 50 is supported by the main frame 30. The motor unit 50 includes an electric motor 52 for driving the vehicle. The motor unit 50 is supported by the main frame 30 via an attachment 60.
[0021] The rotational driving force of the motor unit 50 is transmitted to the rear wheel 14 via a transmission mechanism 27. The transmission mechanism 27 may be, for example, a chain wound around a gear provided on the output shaft of the motor unit 50 and a gear provided on the rear wheel 14. As another example, a circular belt such as a toothed belt may be used as the transmission mechanism.
[0022] The saddle-ride type vehicle 10 includes a battery 82 and a traveling drive circuit 84 for driving the motor unit 50. The battery 82 is a device that stores energy for driving the electric motor 52. Electrical energy supplied from the battery 82 is supplied to the electric motor 52 via the traveling drive circuit 84. The traveling drive circuit 84 is, for example, an inverter circuit. The battery 82 and the traveling drive circuit 84 are also supported by the main frame 30.
[0023] The saddle-ride type vehicle 10 further includes a driver's seat 26 on which a driver sits. The driver can operate the handle device 20 while seated in the driver's seat 26.
[0024] The saddle-ride type vehicle 10 may be provided with a cover 80 that covers the main frame 30 and the motor unit 50 from the left and right. The cover 80 is supported by the main frame 30 in a fixed position.
[0025] The configuration of the main frame 30 will be described in more detail.
[0026] The main frame 30 includes a head pipe 32, a pair of left and right front frames 34, a pair of left and right intermediate frames 36, and a pair of left and right rear frames 38.
[0027] The head pipe 32 is provided on the front side of the main frame 30. The head pipe 32 is disposed in a position that tilts forward as it extends downward.
[0028] A steering shaft 16 is rotatably inserted through the head pipe 32. An upper bracket 16A and an under bracket 16B are supported on the steering shaft 16. A front fork 17 is supported by the upper bracket 16A and the under bracket 16B so as to extend downward. The front wheel 12 is rotatably supported at the lower end of the front fork 17. The front fork 17 forms a front suspension and can absorb impacts that the vehicle 10 receives from the road surface and suppress vibrations of the vehicle 10.
[0029] A handle device 20 is supported by the upper bracket 16A. The handle device 20 includes a pair of left and right handlebars 22. When the rider steers the pair of handlebars 22, the upper bracket 16A, the under bracket 16B, and the front fork 17 rotate around the central axis of the head pipe 32, and the front wheel 12 also rotates around the central axis of the head pipe 32. As a result, the direction of the front wheel 12 can be changed by steering the handle device 20.
[0030] A brake lever is supported on one or both of the pair of handlebars 22. The brake lever is a lever for braking one or both of the front wheel 12 and the rear wheel 14.
[0031] A meter unit that displays information related to the traveling of the saddle-ride type vehicle 10, such as the speed, may be supported on the handle device 20. The meter unit may be supported directly or indirectly on the main frame 30 near the handle device 20.
[0032] The handle device 20 and the meter unit may be provided with an interface device such as a switch for receiving various instructions for the saddle-ride type vehicle 10 .
[0033] A pair of left and right front frames 34 extend rearward from the head pipe 32 while branching out into left and right halves.
[0034] The front frame 34 includes an upper frame portion 34a and a lower frame portion 34b.
[0035] The upper frame portion 34a extends rearward from an upper portion of the head pipe 32. The lower frame portion 34b extends rearward from a lower portion of the head pipe 32. The upper frame portion 34a and the lower frame portion 34b face diagonally downward and rearward from the head pipe 32 in a side view. The upper frame portion 34a extends rearward further than the lower frame portion 34b, reaching the rear end of the motor unit 50. In the portion on the head pipe 32 side, the lower frame portion 34b extends below and parallel to the upper frame portion 34a and faces the front side of the motor unit.
[0036] The upper frame portion 34a and the lower frame portion 34b are connected by a plurality of connecting frames 34c between the head pipe 32 and the motor unit 50. The plurality of connecting frames 34c connect the upper frame portion 34a and the lower frame portion 34b to form a truss structure.
[0037] The battery 82 may be positioned between the pair of left and right front frames 34 and supported by the front frames 34 .
[0038] On each of the left and right sides, the intermediate frame 36 extends downward from the rear end of the upper frame portion 34a.
[0039] The intermediate frame 36 extends from the rear end of the upper frame portion 34a, passing behind the motor unit 50, and up and down to the lower end position of the motor unit 50 or below this lower end position. A pivot shaft 37 is supported at the middle portion of the intermediate frame 36. The pivot shaft 37 has a central axis that extends along the vehicle width direction. The swing arm 28 is supported on the pivot shaft 37 so that it can swing.
[0040] The swing arm 28 extends obliquely downward from a longitudinally intermediate portion of the intermediate frame 36. The rear wheel 14 is rotatably supported at the rear end of the swing arm 28. The swing arm 28 swings to allow the rear wheel 14 to move up and down. The intermediate frame 36 may also be referred to as a pivot bracket. The intermediate frame 36 is located rearward of an attachment 60, which will be described later, and is an example of an arm support frame that supports the swing arm 28.
[0041] The main frame 30 includes a plurality of attachment targets 31A, 31B, 31C1, and 31C2. In this embodiment, the attachment targets 31A, 31B, 31C1, and 31C2 are provided at the rear end of the lower frame portion 34b, an upper portion of the intermediate frame 36, and a lower portion of the intermediate frame 36.
[0042] For example, the attachment target portion 31A is provided at the rear end portion of the lower frame portion 34b. For example, the attachment target portion 31A is a cylindrical member having a screw hole through which a screw S can be inserted along the vehicle width direction.
[0043] Also, for example, an attachment target portion 31B is provided in a lower portion of the intermediate frame 36. The attachment target portion 31B is, for example, a bracket formed at the lower end of the intermediate frame 36. The bracket is fixed to the lower portion of the intermediate frame 36 by welding or the like, and a screw insertion hole is formed in the bracket.
[0044] Also, for example, attachment targets 31C1 and 31C2 are provided in an upper portion of the intermediate frame 36. For example, as shown in Fig. 2, attachment target 31C1 is a screw hole portion formed between the upper end of the intermediate frame 36 and the pivot shaft 37. Also, for example, as shown in Fig. 3, attachment target 31C2 is a bracket attached by welding or the like between the upper end of the intermediate frame 36 and the pivot shaft 37. It is preferable that a screw hole is formed in the bracket.
[0045] Mounting targets 31A, 31B, and 31C1 are provided on the left side of vehicle 10, and mounting targets 31A, 31B, and 31C2 are provided on the right side. Mounting target 31A is an example of a front mounting target located forward of rotation axis X of electric motor 52. Mounting targets 31B, 31C1, and 31C2 are examples of rear mounting targets located rearward of rotation axis X.
[0046] The number and positions of the plurality of attachment targets 31A, 31B, 31C1, and 31C2 are not limited to the above example.
[0047] The motor unit 50 is attached to a plurality of attachment targets 31A, 31B, 31C1, and 31C2 via attachments 60.
[0048] Because the attachment 60 is attached to the attachment target portion 31A of the front frame 34 and also to the attachment target portions 31B, 31C1, and 31C2 of the intermediate frame 36, the attachment 60 can function as a rigid body that connects and supports the front frame 34 and the intermediate frame 36. Therefore, for example, a driving force for forward movement generated by contact between the ground and the rear wheels 14 is effectively transmitted from the intermediate frame 36 to the front frame 34 via the attachment 60, and the driving force is effectively received by the entire vehicle 10. Since the force at this time is received mainly by the attachment 60, the external force is unlikely to act on the electric motor 52.
[0049] On each of the left and right sides, a rear frame 38 extends obliquely upward and rearward from the rear half of the front frame 34. In this embodiment, the rear frame 38 is composed of multiple frames 38a, 38b. The first rear frame 38a extends obliquely upward from the longitudinal center of the upper frame portion 34a. The second rear frame 38b extends obliquely upward from the rear end of the upper frame portion 34a and is connected to the first rear frame 38a.
[0050] The traveling drive circuit 84 may be located between the pair of left and right rear frames 38 and supported by the pair of left and right rear frames 38 .
[0051] The driver's seat 26 may be located above the pair of left and right rear frames 38 and may be supported by the pair of left and right rear frames 38. A tandem seat may be provided behind the driver's seat 26.
[0052] A rear suspension 29 is interposed between the rear frame 38 and the swing arm 28. The rear suspension 29 can absorb shocks that the vehicle 10 receives from the road surface and suppress vibrations of the vehicle 10.
[0053] The main frame 30 is a rigid member made of metal or the like. The main frame 30 may be formed, for example, by a frame made by bending and welding metal pipes, a cast frame, or a combination thereof. The portion of the main frame 30 that includes the attachment targets 31A, 31B, 31C1, and 31C2 and that keeps the positional relationship of the attachment targets 31A, 31B, 31C1, and 31C2 constant may be formed as an integrated part by bending, casting, welding, or the like, and may be difficult to disassemble without being destroyed.
[0054] The specific frame shape of the main frame 30 can be changed as appropriate depending on the strength, support locations, or design requirements.
[0055] The structure for attaching the motor unit 50 to the main frame 30 will now be described in more detail.
[0056] FIG. 2 is a side view showing the motor unit 50 attached to the main frame 30 via the attachment 60. FIG. 3 is a side view seen from the opposite side to FIG. 2. FIG. 4 is a front view showing the motor unit 50 attached to the main frame 30 via the attachment 60. In FIG. 4, the main frame 30 is partially shown by a two-dot chain line. FIG. 5 is an explanatory diagram showing the motor unit 50 in the middle of being attached to the attachment 60. In FIG. 5, the motor unit 50 is shown by a two-dot chain line. FIG. 6 is an explanatory diagram showing the attachment 60 in the middle of being attached to the main frame 30. In FIG. 6, the motor unit 50 attached to the attachment 60 is omitted.
[0057] The motor unit 50 includes an electric motor 52. The electric motor 52 includes an armature and a field element therein and is formed, for example, in a cylindrical shape. The electric motor 52 is supported on the main frame 30 via an attachment 60 with the rotation axis X aligned along the vehicle width direction.
[0058] An introduction portion 52a into which a power line Wa drawn from the traveling drive circuit 84 is introduced may be provided at one axial end of the electric motor 52. An introduction portion 52b into which a signal line Wb is introduced may be provided at one axial end of the electric motor 52. The signal line Wb may be connected to, for example, a sensor for detecting the state of the electric motor 52. The introduction portions 52a, 52b may be connectors into which connectors provided at the ends of the power line Wa or the signal line Wb are connected, or may be insertion holes for electric wires or cables through which the power line Wa or the signal line Wb is directly inserted. If multiple of the multiple power line Wa and signal line Wb are bundled together and introduced into the electric motor 52, the space occupied by the wiring can be shortened and the connection to the electric motor 52 can be facilitated.
[0059] Motor unit 50 may include a rotational driving force transmission mechanism 56. The rotational driving force transmission mechanism is a mechanism that transmits power to rear wheel 14 on one side in the vehicle width direction. Rotational driving force transmission mechanism 56 may be a speed change mechanism that changes the rotational speed of electric motor 52 at a constant gear ratio or a variable gear ratio. For example, rotational driving force transmission mechanism 56 may be a constant speed change mechanism that includes a gear connected to the output shaft of electric motor 52, a gear whose rotation is transmitted to transmission mechanism 27, and a circular chain wound around these gears.
[0060] The rotational driving force transmission mechanism 56 may have a flat shape that is long in one direction so that multiple gears can be arranged at staggered positions. The rotational driving force transmission mechanism 56 may be arranged on one axial side of the electric motor 52 and integrated with the electric motor 52. As a result of the rotational driving force transmission mechanism 56 being formed in a flat shape that is long in one direction, a portion of the rotational driving force transmission mechanism 56 may protrude beyond the outer shape of the electric motor 52 in a side view. In this embodiment, the rotational driving force transmission mechanism 56 protrudes obliquely upward from the electric motor 52.
[0061] The rotational drive force transmission mechanism does not have to change the rotational speed of the electric motor 52. A driving drive circuit 84 such as an inverter circuit may be integrated into the motor unit 50. The rotational drive force transmission mechanism may not be integrated into the motor, but may be mounted on the vehicle as a separate entity from the motor.
[0062] The motor unit 50 includes motor-side mounting targets 53a, 53b, and 53c. The motor-side mounting targets 53a, 53b, and 53c may be, for example, portions that partially protrude from the outer periphery of the electric motor 52. For example, the motor-side mounting targets 53a, 53b, and 53c are provided protruding from each of three positions that divide the outer periphery of the electric motor 52 into equal parts. The motor-side mounting targets 53a, 53b, and 53c are formed in a protruding shape that is elongated in the axial direction of the electric motor 52. Threaded holes are formed at both ends of the motor-side mounting targets 53a, 53b, and 53c. The motor unit 50 may also have screw-fastening points prepared for other models.
[0063] The motor unit 50 is attached to the main frame 30 via an attachment 60 .
[0064] The attachment 60 is a component to which the motor unit 50 is attached. The attachment 60 may be formed of a metal plate or a metal pipe. The attachment 60 includes a plurality of mounting portions 68A, 68B, 68C, 78A, 78B, and 78C and rigid portions 63 and 73. The mounting portions 68A, 68B, 68C, 78A, 78B, and 78C are attached to the plurality of mounting targets 31A, 31B, 31C1, and 31C2, respectively. For example, on the left side, the mounting portions 68A, 68B, and 68C are attached to the plurality of mounting targets 31A, 31B, and 31C1, respectively. On the right side, the mounting portions 78A, 78B, and 78C are attached to the plurality of mounting targets 31A, 31B, and 31C2, respectively. Rigid portions 63 and 73 are portions that connect multiple mounting portions 68A, 68B, 68C, 78A, 78B, and 78C. More specifically, on the left side, rigid portion 63 connects multiple mounting portions 68A, 68B, and 68C and maintains a fixed positional relationship. On the right side, rigid portion 73 connects multiple mounting portions 78A, 78B, and 78C and maintains a fixed positional relationship.
[0065] In this embodiment, the attachment 60 includes a first attachment divided part 64, a second attachment divided part 74, and a connecting part 70.
[0066] The first attachment divided part 64 has a plurality of mounting portions 68A, 68B, 68C and a rigid portion 63 connecting the plurality of mounting portions 68A, 68B, 68C. The second attachment divided part 74 has a plurality of mounting portions 78A, 78B, 78C and a rigid portion 73 connecting the plurality of mounting portions 78A, 78B, 78C. A motor unit 50 is attached to each of the first attachment divided part 64 and the second attachment divided part 74.
[0067] The connecting part 70 is a long portion that connects the first attachment divided part 64 and the second attachment divided part 74 while arranging them side by side at an interval in the vehicle width direction.
[0068] A more specific example will be described.
[0069] The rigid portion 63 of the first attachment divided part 64 is formed in an annular shape surrounding the motor unit 50 in a side view. In this embodiment, the rigid portion 63 is formed in an annular shape surrounding the electric motor 52.
[0070] The rigid portion 63 has a lower component 65 and an upper component 66. The lower component 65 is formed in a partially annular shape that opens upward in a side view. In this embodiment, the lower component 65 is formed in a J-shape with its rear end longer upward than its front end. The upper component 66 is an elongated member that can be arranged to span both ends of the lower component 65. Here, the upper component 66 is curved so as to be convex upward.
[0071] By connecting both ends of the lower component 65 and both ends of the upper component 66, the lower component 65 and the upper component 66 are combined to form a ring. For example, screw insertion holes hc are formed at both ends of the lower component 65 and both ends of the upper component 66. With each end of the lower component 65 and each end of the upper component 66 overlapping, the lower component 65 and the upper component 66 are combined using screws S, nuts N, or the like. The upper component 66 functions as an upper rigid portion located above the motor unit 50.
[0072] Two screw insertion holes hm are formed in a longitudinally intermediate portion of the lower component 65. The two screw insertion holes hm are positioned apart in the longitudinal direction of the lower component 65. Screw insertion holes hm are formed in a longitudinally intermediate portion of the upper component 66. The motor side mounting targets 53a, 53b, and 53c of the motor unit 50 are disposed inside these screw insertion holes hm. The motor unit 50 is attached to the lower component 65 and the upper component 66 inside the screw insertion holes hm using screws S. In other words, the portions of the attachment 60 where the screw insertion holes hm for attaching the motor side mounting targets 53a, 53b, and 53c are formed are the motor mounting portions Pa.
[0073] A screw insertion hole hr is formed in a position near the front end of the lower component 65, a screw insertion hole hr is formed in a longitudinal intermediate portion of the lower component 65, and a screw insertion hole hr is formed in a position near the rear end of the lower component 65. The screw insertion hole hr in the longitudinal intermediate portion of the lower component 65 is located below the screw insertion hole hr near the rear end of the lower component 65.
[0074] The extension piece 67 is disposed via a boss in a portion of the lower component 65 where the screw insertion hole hr is formed near the rear end. The extension piece 67 is attached to the lower component 65 at a position near the rear end using a screw S or the like. The extension piece 67 extends toward the rear. For example, the extension piece 67 is formed in the shape of a plate that widens vertically as it extends rearward in a side view. A screw insertion hole he is formed at the rear end of the extension piece 67. Here, two screw insertion holes he are formed in the extension piece 67, one above the other.
[0075] The second attachment divided part 74 has a similar configuration to the first attachment divided part 64, and the following description will focus on the differences between the first attachment divided part 64 and the second attachment divided part 74.
[0076] That is, similar to the rigid portion 63, the rigid portion 73 of the second attachment divided part 74 is formed in a ring shape surrounding the motor unit 50 in a side view.
[0077] The rigid portion 73 has a lower part 75 and an upper part 76. The lower part 75 corresponds to the lower part 65, and the upper part 76 corresponds to the upper part 66.
[0078] The rear end of the lower component 75 is shorter than the rear end of the lower component 65, and has a shape that omits the portion of the rear end of the lower component 65 where the screw insertion hole hc is formed. The screw insertion hole hc for coupling with the upper component 76 is formed in a position near the rear end of the lower component 75 and closer to the middle in the longitudinal direction than the screw insertion hole hr in the rear end of the lower component 75.
[0079] Furthermore, the rear end of the upper component 76 is bent downward more than the rear end of the upper component 66. The rear end of the upper component 76 is placed over the portion of the lower component 75 where the screw insertion holes hc are formed. In this state, both ends of the upper component 76 are attached to both ends of the lower component 75 using screws S or the like.
[0080] The extension piece 67 is omitted in the second attachment divided part 74. The rear end of the lower part 75 is attached to the main frame 30 by utilizing the rear screw insertion hole hrc.
[0081] Other configurations of the lower part 75 and the upper part 76 of the second attachment divided part 74 may be the same as those of the lower part 65 and the upper part 66 described above.
[0082] In this embodiment, the portion of the lower components 65, 75 where the screw insertion hole hr is formed near the front end is the front mounting portion 68A, 78A that is mounted to the mounting target portion 31A as the front mounting target portion. The portion of the lower components 65, 75 where the screw insertion hole hr is formed in the middle in the longitudinal direction is the first rear mounting portion 68B, 78B that is mounted to the mounting target portion 31B as the rear mounting target portion. The portion of the lower component 65 where the screw insertion hole he is formed near the rear end is the second rear mounting portion 68C that is mounted to the mounting target portion 31C1 as the rear mounting target portion. The portion of the lower component 75 where the screw insertion hole hrc is formed near the rear end is the second rear mounting portion 78C that is mounted to the mounting target portion 31C2 as the rear mounting target portion. The first rear mounting portions 68B, 78B and the second rear mounting portions 68C, 78C are both examples of rear mounting portions located rearward of the rotation axis X.
[0083] In addition, the portions of the rigid portions 63, 73 between the front mounting portions 68A, 78A and the first rear mounting portions 68B, 78B are lower rigid portions 63A, 73A that connect the front mounting portions 68A, 78A and the first rear mounting portions 68B, 78B on the lower side of the motor unit 50.
[0084] At least one of the mounting portions 68A, 68B, 68C, 78A, 78B, and 78C is an outer mounting portion that is located on the outer side of the main frame 30 in the vehicle width direction and is attached to the main frame. In the present embodiment, the mounting portion 68C is an outer mounting portion that is arranged on the outer side of the mounting target portion 31C1 of the main frame 30 and is attached to the mounting target portion 31C1 by screwing or the like. The other mounting portions 68A, 68B, 78A, 78B, and 78C are inner mounting portions that are located on the inner side of the main frame 30 in the vehicle width direction and are attached to the main frame 30.
[0085] By arranging the other mounting portions 68A, 68B, 78A, 78B, 78C on the inner side in the vehicle width direction relative to the main frame 30, it becomes easier to arrange the mounting structure of the attachment 60 on the inner side of the main frame 30, making it possible to make the vehicle 10 more compact. Also, by making some, in this case only one mounting portion 68C, an outer mounting portion, it becomes easier to mount that mounting portion 68C to the main frame 30.
[0086] For example, if one were to attempt to place all of the attachment's mounting portions inside the main frame, the main frame itself would get in the way, potentially making it difficult to place the attachment inside the main frame. In this embodiment, the other mounting portions 68A, 68B, 78A, 78B, and 78C of the attachment 60 can be first placed inside the main frame 30, and then mounting portion 68C can be placed last outside the mounting target portion 31C1 of the main frame 30. This makes it easier to assemble the attachment 60 to the main frame 30.
[0087] The first attachment divided part 64 is located on the side where the transmission mechanism 27 is located in the vehicle width direction, in this case, the left side. At least one of the mounting parts 68A, 68B, 68C of the first attachment divided part 64 is attached to the intermediate frame 36 that supports the swing arm 28. In particular, the mounting part 68C extends further rearward from the rear end part of the lower part 65 and is attached to the mounting target part 31C1 of the intermediate frame 36.
[0088] The gear on the motor unit 50 side, around which the transmission mechanism 27 is wound, is located forward of the mounting portions 68B, 68C. The gear on the rear wheel 14 side, around which the transmission mechanism 27 is wound, is located rearward of the mounting portions 68B, 68C. For this reason, the tension caused by the circular rotation of the transmission mechanism 27 may act as a force pulling the left side portion of the motor unit 50 and the left side portion of the rear wheel 14 together. When the mounting portions 68B, 68C are attached to the intermediate frame 36, this force is effectively absorbed. In particular, the mounting portion 68C extends rearward from the attachment 60 and is supported by the intermediate frame 36, so that the force is effectively absorbed.
[0089] The connecting parts 70 are formed in an elongated shape, here, a cylindrical or columnar shape. In this embodiment, the attachment 60 includes three connecting parts 70. The connecting parts 70 are located between the mounting parts 68A and 78A, between the mounting parts 68B and 78B, and between the mounting part 78C and a portion of the lower part 65 where the screw insertion hole hr is formed near the rear end, and are fixed to the lower parts 65 and 75 by screws or the like. As a result, the first attachment separate part 64 and the second attachment separate part 74 are connected by the connecting parts 70 while being spaced apart in the vehicle width direction. Here, the screws used for screwing may be long screws that penetrate from left to right, or may be separate short screws on the left and right. For example, long screws may be used for at least the front mounting parts 68A and 78A, and separate short screws on the left and right may be used for the other mounting parts. Long screws are advantageous in terms of reducing the number of parts and increasing rigidity. For example, if long screws are used at least in the front mounting portions 68A and 78A, the long screws can more easily withstand the force caused by operating the handle. Also, short screws are advantageous in terms of weight reduction.
[0090] The connecting part 70 located between the mounting part 68A and the mounting part 78A is an example of a front connecting part located forward of the rotation axis X of the motor unit 90. The connecting part 70 located on the front side effectively receives the force resulting from the operation of the handle device 20.
[0091] The motor unit 50 is attached to the first attachment divided part 64 and the second attachment divided part 74 at the positions of the screw insertion holes hm, three screw insertion holes hm on each side in this example. The screw insertion holes hm are located between the attachment targets 31A, 31B, 31C1, and 31C2.
[0092] More specifically, in the attached state, the positions of attachment targets 31A, 31B, 31C1, and 31C2 correspond to the positions of attachment portions 68A, 68B, 68C, 78A, 78B, and 78C, respectively. In first attachment divided part 64, screw insertion holes hm are located between attachment portions 68A and 68B, between attachment portions 68B and 68C, and between attachment portions 68C and 68A. In second attachment divided part 74, screw insertion holes hm are located between attachment portions 78A and 78B, between attachment portions 78B and 78C, and between attachment portions 78C and 78A.
[0093] The mounting position of the motor unit 50 does not need to be the center of the adjacent mounting portions 31A, 31B, 31C1, and 31C2 in each of the first attachment separate part 64 and the second attachment separate part 74. However, the mounting position of the motor unit 50 may be located within a range of 30%, preferably 20%, of the entire straight line distance between the adjacent mounting portions 31A, 31B, 31C1, and 31C2, with the midpoint as the center.
[0094] The axial length of the electric motor 52 in the motor unit 50 may be set to be greater than the distance between the first attachment divided part 64 and the second attachment divided part 74. In this case, the motor-side mounting targets 53a, 53b, 53c should be formed to a length that allows them to be placed between the first attachment divided part 64 and the second attachment divided part 74.
[0095] The electric motor 52 is disposed between the first attachment divider 64 and the second attachment divider, and the motor-side mounting portions 53a, 53b, and 53c are disposed between the first attachment divider 64 and the second attachment divider 74. In this state, the screw S passes through the screw insertion hole hm of the first attachment divider 64, the screw insertion holes of the motor-side mounting portions 53a, 53b, and 53c, and further through the screw insertion hole hm of the second attachment divider 74, and is screwed into the nut N. This completes the attachment of the motor unit 50 to the attachment 60.
[0096] In this state, the introduction portions 52a and 52b of the electric motor 52 may be located on the outer side of the second attachment divided part 74 in the vehicle width direction, for example, on the outer right side.
[0097] Furthermore, the rotational drive force transmission mechanism 56 is integrated with the other end side of the electric motor 52. The rotational drive force transmission mechanism 56 may be located outward in the vehicle width direction from the first attachment divided part 64, for example, on the left outer side.
[0098] As described above, since the upper components 66, 76 are attached to the lower components 65, 75, the electric motor 52 can be placed inside the lower components 65, 75, and then the upper components 66, 76 can be attached to the lower components 65, 75. Therefore, even if the motor unit 50 partially protrudes outside the first attachment separate component 64 or the second attachment separate component in the vehicle width direction, the motor unit 50 can be easily assembled into the attachment 60.
[0099] An example of a procedure for attaching the motor unit 50 to the main frame 30 using the attachment 60 will now be described.
[0100] First, as shown in FIG. 5 , lower components 65, 75 connected via connecting component 70 are prepared. Then, electric motor 52 of motor unit 50 is placed inside lower components 65, 75 through the upper openings of lower components 65, 75. Then, screws S are inserted through screw insertion holes hm of lower components 65, 75 and motor-side mounting portions 53a, 53b of electric motor 52, and are screwed and fastened to nuts N. In this way, motor unit 50 is mounted to lower components 65, 75.
[0101] Thereafter, both ends of the upper components 66, 76 are attached to both ends of the lower components 65, 75 by screwing or the like. Also, before and after this attachment, screws S are inserted through the screw insertion holes hm of the upper components 66, 76 and the motor-side attachment target portion 53c of the electric motor 52, and are screwed and fastened to the nuts N. In this way, the motor unit 50 is also attached to the upper components 66, 76. Note that, because the rear end of the lower component 65 protrudes above the rear end of the lower component 75, the rear end of the upper component 66 and the rear end of the lower component 65 can be easily fastened together.
[0102] At an optional stage, an extension piece 67 is attached to the lower part 65.
[0103] Thereafter, as shown in Fig. 6, attachment 60 is attached to main frame 30. At this time, mounting portions 68A, 68B, 78A, 78B, and 78C are placed inside mounting targets 31A, 31B, and 31C2, and the mounting work is performed using screws or the like. After this, mounting portion 68C is placed outside mounting target 31C1. Then, mounting portion 68C is attached to mounting target 31C1 using screws or the like.
[0104] As a result, the motor unit 50 is attached to the main frame 30 via the attachment 60 .
[0105] When the motor unit 50 is attached to the main frame 30, the lead-in portions 52a, 52b of the electric motor 52 are located outside the attachment division parts 64, 74. This allows for easy routing and connection of the wiring Wa, Wb to the lead-in portions 52a, 52b.
[0106] The rotational drive force transmission mechanism 56 is also located outside the attachment dividers 64, 74. This allows for easy assembly of the transmission mechanism 27 to the rotational drive force transmission mechanism 56. The rotational drive force transmission mechanism 56 may be assembled to the electric motor 52 after the electric motor 52 is attached to the main frame 30. Even in this case, the rotational drive force transmission mechanism 56 is located outside the attachment dividers 64, 74, allowing for easy assembly of the rotational drive force transmission mechanism 56 outside the attachment dividers 64, 74.
[0107] There is a possibility that different types of motor units 50 may be prepared for attachment to the saddle-ride type vehicle 10. For example, there is a possibility that motor units with different specifications and different outputs may be prepared for the saddle-ride type vehicle 10. As shown in Figure 7, it is assumed that a motor unit 90 having a different shape from the motor unit 50 is mounted on the saddle-ride type vehicle 10.
[0108] It may be difficult to change the shape of the main frame 30 in accordance with the external shape of the motor unit 90. The main frame 30 is designed not only from the viewpoint of strength, which assumes various behaviors during driving, but also from various viewpoints such as production efficiency, design, and cost, and therefore, changing some of the support points of the main frame 30 may disrupt the overall balance, and may not satisfy all of the above viewpoints.
[0109] Therefore, an attachment 92 corresponding to a motor unit 90 of a different shape is prepared. The attachment 92 has mounting portions 68A, 68B, 68C, 78A, 78B, and 78C at the same positions as the attachment 60. However, the shape of the rigid portion 93 of the attachment 92 is changed according to the shape of the motor unit 90. Furthermore, a screw insertion hole hm corresponding to the shape of the motor unit 90 is formed in the changed rigid portion 93.
[0110] The motor unit 90 is attached to an attachment 92 , and the attachment 92 is attached to the main frame 30 .
[0111] It should be noted that differences in the external shape of the motor unit may be caused by changes in the design of the motor unit, etc.
[0112] The method of manufacturing the saddle-ride type vehicle 10 using the attachments 60, 92 will be explained as shown in the flowchart of FIG.
[0113] That is, for a saddle-ride type vehicle 10 having a predetermined main frame 30, a plurality of types of motor units 50, 90 are prepared as shown in step S1.
[0114] In the next step S2, a plurality of types of attachments 60, 92 are prepared in accordance with the plurality of types of motor units 50, 90.
[0115] In the next step S3, the type of the motor unit 50, 90 to be supported is determined.
[0116] In the next step S4, the types of attachments 60, 92 are selected according to the types of motor units 50, 90 to be supported.
[0117] In the next step S5, the motor units 50, 90 are attached to the selected attachments 60, 92.
[0118] In the next step S6, the motor units 50, 90 are attached to the main frame 30 via the attachments 60, 92.
[0119] This allows motor units 50 and 90 of different shapes to be attached to a common main frame 30.
[0120] In the case where the motor unit is attached to the main frame without an attachment, a motor unit of a different shape may be attached to the main frame via an attachment.
[0121] With the saddle-ride type vehicle 10 and attachment 60 configured as described above, the motor unit 50 is attached to the main frame 30 via the attachment 60. Therefore, by changing the shape of the attachment 60, 92 or by changing whether or not an attachment is present, different types of motor units 50, 90 can be mounted on the saddle-ride type vehicle 10. This allows for overall cost reduction when using multiple types of motor units 50. Furthermore, it is easy to accommodate changes in the shape and specifications of the motor unit 50. When the attachment 60 is used, the main frame is reinforced by the rigid portions 63, 73 of the attachment 60. Therefore, the rigidity of the saddle-ride type vehicle 10 is easily ensured.
[0122] Furthermore, since the force applied to the main frame 30 is not easily transmitted to the motor unit 50, the motor unit 50 is not easily distorted.
[0123] The number and positions at which the motor units 50 are attached to the attachment 60 are optional. For each of the first attachment divided part 64 and the second attachment divided part 74, the motor units 50 are preferably fixed to the attachment 60 at three locations.
[0124] Furthermore, the rigid portions 63, 73 have lower rigid portions 63A, 73A that connect the mounting portions 68A, 78A as front mounting portions and the first rear mounting portions 68B, 78B. Therefore, below the motor unit 50, the lower rigid portions 63A, 73A are interposed between the mounting target portion 31A as the front mounting target portion of the main frame 30 and the mounting target portion 31B as the rear mounting target portion, thereby ensuring the rigidity of the main frame 30. This effectively absorbs the transmission of force from the rear wheel 14 for forward travel and the fore-and-aft displacement of the front wheel 12. Furthermore, the lower rigid portions 63A, 73A can support the motor unit 50 from below.
[0125] Furthermore, the rigid portions 63, 73 have upper parts 66, 76 as upper rigid portions, and the motor unit 50 is attached to the upper parts 66, 76, so that the motor unit 50 can be supported as if suspended from the upper parts 66, 76.
[0126] Furthermore, since the rigid portions 63, 73 are formed in an annular shape surrounding the motor unit 50 in a side view, the rigidity of the saddle-ride type vehicle 10 is easily ensured and the motor unit 50 is easily supported firmly.
[0127] Furthermore, the rigid portion 63 has lower components 65, 75 that form a partial ring shape that opens upward, and upper components 66, 76 that close the upward openings of the lower components 65, 75 in a side view. This makes it easy to attach the motor unit 50 to the lower components 65, 75 while placing the motor unit 50 inside the lower components 65, 75. After this, the upper components 66, 76 can be attached to the lower components 65, 75, making the rigid portions 63, 73 ring-shaped. This makes it easy to attach the motor unit 50 inside the ring-shaped rigid portions 63, 73.
[0128] The attachment 60 also includes a first attachment divided part 64, a second attachment divided part 74, and a connecting part 70 that connects the attachment divided parts 64, 74 while arranging them at intervals in the vehicle width direction. The first attachment divided part 64 and the second attachment divided part 74 each have multiple mounting parts 68A, 68B, 68C, 78A, 78B, 78C and rigid parts 63, 73, and are attached to the motor unit 50. This allows the motor unit 50 to be firmly held. The first attachment divided part 64 and the second attachment divided part 74 also provide high rigidity to the main frame 30.
[0129] Furthermore, at least one of the multiple mounting portions 68A, 68B, 68C of the first attachment divided part 64 is an outer mounting portion that is located on the outer side of the main frame 30 in the vehicle width direction and is attached to the main frame 30. Therefore, mounting portion 68C as the outer mounting portion does not need to be positioned on the inner side of the main frame 30 in the vehicle width direction, making it easier to attach the attachment 60 to the main frame 30.
[0130] Furthermore, at least one of the mounting portions 68B, 68C of the first attachment divided part 64 is attached to the intermediate frame 36, which serves as an arm support frame. Therefore, the force of the transmission mechanism 27 is effectively received by the intermediate frame 36.
[0131] Furthermore, the introduction portions 52a, 52b of the wiring Wa, Wb to the motor unit 50 or the motor rotational drive force transmission mechanism 56 are located outside the first attachment divider 64 or the second attachment divider 74 in the vehicle width direction. This makes it easier to route the wiring Wa, Wb compared to when the introduction portions 52a, 52b are located between the attachment dividers 64, 74. Furthermore, if the rotational drive force transmission mechanism 56 is located outside the attachment dividers 64, 74 in the vehicle width direction, it becomes easier to assemble the motor unit 50 to the attachment 60. It also becomes easier to assemble the transmission mechanism 27.
[0132] Furthermore, the attachment position of the motor unit 50 on the attachment 60 is located between the multiple attachment targets 31A, 31B, 31C1, and 31C2. Therefore, deformation of the main frame 30 is unlikely to directly affect the motor unit 50.
[0133] Furthermore, according to the manufacturing method of the saddle-ride type vehicle 10, by changing the type of attachment 60, 92, different types of motor units 50, 90 can be easily mounted on the saddle-ride type vehicle 10 having a common main frame 30.
[0134] {Second embodiment} A saddle-ride type vehicle according to the second embodiment will be described. Fig. 9 is a schematic side view showing a state in which a motor unit 50 is attached via an attachment 160 to a main frame 130 corresponding to the main frame 30 in the saddle-ride type vehicle.
[0135] Unlike the main frame 30, the main frame 130 does not include the intermediate frame 36. The main frame 130 includes two attachment target portions 131A and 131B located at a distance from each other in the front and rear.
[0136] The attachment 160 includes a lower part 165 that is open at the top, and an upper part 166 that closes the upper opening of the lower part 165. The lower part 165 and the upper part 166 may be provided on each of the left and right sides.
[0137] The annular attachment 160 is formed by fastening both ends of the upper part 166 to both ends of the lower part 165 with screws or the like.
[0138] The front end of lower part 165 and the front end of upper part 166 are attached to attachment target part 131A by screwing etc. The rear end of lower part 165 and the rear end of upper part 166 are attached to attachment target part 131B by screwing etc.
[0139] The motor unit 50 is attached by screws or the like to two locations in the longitudinal middle of the lower part 165 and one location in the longitudinal middle of the upper part 166 .
[0140] Unlike the first embodiment, the attachment 160 includes a pivot support portion 170 that swingably supports the swing arm 28. In this embodiment, the pivot support portion 170 is provided on the rear portion of the lower part 165. The pivot support portion 170 is, for example, a tubular part that extends along the vehicle width direction, and is fixed to the lower part 165 by welding or the like.
[0141] According to this embodiment, when considering a change in the design of the swing arm 28, it can be accommodated mainly by changing the swing arm 28, without having to change the main frame. Also, the attachment 160 supporting the swing arm 28 can be attached to the main frame 130. The attachment 160 and the main frame 130 can be unitized in a location separate from the assembly location of the main frame 130, and the unitized attachment 160 and main frame 130 can be attached to the main frame 130, which simplifies manufacturing.
[0142] The attachment 160 may be provided with a support portion that supports the rear suspension or a link connected to the rear suspension.
[0143] {Variation} In the first and second embodiments, the motor unit only needs to include a motor. The motor is a prime mover that converts energy into power, and does not necessarily have to be an electric motor. The motor may also be an internal combustion engine.
[0144] The saddle-ride type vehicle may be a vehicle that includes both an electric motor and an internal combustion engine as motors.
[0145] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory.
[0146] {Note} The present specification and drawings disclose the following aspects.
[0147] The first aspect is a saddle-type vehicle comprising a main frame including a plurality of mounting targets, a motor unit including a motor, and an attachment to which the motor unit is attached, the attachment including a plurality of mounting parts attached to each of the plurality of mounting targets, and a rigid part connecting the plurality of mounting parts.
[0148] According to the first aspect, the motor unit is attached to the main frame via an attachment. Therefore, different types of motor units can be mounted on a saddle-ride type vehicle by changing the shape of the attachment or by changing whether or not an attachment is present, without making major changes to the main frame. In other words, different types of motor units can be mounted on a saddle-ride type vehicle by making small changes to the smaller attachment rather than a larger main frame. When an attachment is used, the main frame is reinforced by the rigid portion of the attachment. This makes it easier to ensure the rigidity of the saddle-ride type vehicle.
[0149] A second aspect is a saddle-type vehicle according to the first aspect, wherein the plurality of mounting targets include a front mounting target located forward of the rotation shaft of the motor and a rear mounting target located rear of the rotation shaft, the plurality of mounting targets include a front mounting portion attached to the front mounting target portion and a rear mounting portion attached to the rear mounting target portion, and the rigid portion includes a lower rigid portion below the motor unit that connects the front mounting portion and the rear mounting portion.
[0150] In this case, the lower rigid portion is interposed between the front and rear attachment target portions of the main frame below the motor unit, thereby ensuring the rigidity of the main frame.
[0151] A third aspect is a saddle-type vehicle according to the first or second aspect, wherein the rigid portion has an upper rigid portion located above the motor unit, and the motor unit is attached to the upper rigid portion.
[0152] In this case, the motor unit can be supported so as to be suspended from the upper rigid portion.
[0153] A fourth aspect is the saddle-ride type vehicle according to any one of the first to third aspects, wherein the rigid portion is formed in an annular shape surrounding the motor unit in a side view.
[0154] In this case, since the rigid portion has a ring shape surrounding the motor unit, the rigidity of the saddle-ride type vehicle is easily ensured, and the motor unit is easily supported firmly.
[0155] A fifth aspect is a saddle-type vehicle according to the fourth aspect, wherein the rigid portion has a lower part that is partially annular and opens upward in a side view, and an upper part that closes the upward opening of the lower part in a side view.
[0156] This allows the motor unit to be mounted to the lower component while the motor unit is positioned within the lower component. After this, the upper component can be mounted to the lower component to form the rigid portion into a ring shape. This makes it easy to mount the motor unit within the ring-shaped rigid portion.
[0157] A sixth aspect is a saddle-type vehicle according to any one of the first to fifth aspects, wherein the attachment includes a first attachment separate part, a second attachment separate part, and a connecting part that connects the first attachment separate part and the second attachment separate part in a state where they are spaced apart in the vehicle width direction, and each of the first attachment separate part and the second attachment separate part has the multiple mounting portions and the rigid portion and is attached to the motor unit.
[0158] This allows the motor unit to be firmly held by the first attachment divided part and the second attachment divided part, and also allows the main frame to have high rigidity due to the first attachment divided part and the second attachment divided part.
[0159] A seventh aspect is the saddle-ride type vehicle according to the sixth aspect, wherein the connecting part includes a front connecting part located forward of the rotation shaft of the motor.
[0160] This allows the force caused by the steering operation to be effectively received by the front connecting part.
[0161] An eighth aspect is a saddle-type vehicle according to the sixth or seventh aspect, wherein at least one of the plurality of mounting portions of the first attachment divided part is an outer mounting portion that is positioned on the outer side of the main frame in the vehicle width direction and is attached to the main frame.
[0162] In this case, the outer mounting portion does not need to be positioned on the inner side of the main frame in the vehicle width direction, making it easier to mount the attachment to the main frame.
[0163] A ninth aspect is a saddle-type vehicle according to any one of the sixth to eighth aspects, wherein the main frame is located rearward of the attachment and includes an arm support frame that supports a swing arm, the motor unit includes a transmission mechanism on one side of the vehicle width that transmits power to the rear wheel, the first attachment separate part is located on the side of the vehicle width where the transmission mechanism is located, and at least one of the multiple mounting portions of the first attachment separate part is attached to the arm support frame.
[0164] As a result, the force applied to the transmission mechanism is received by the arm support frame.
[0165] A tenth aspect is a saddle-type vehicle according to any one of the sixth to ninth aspects, wherein the wiring introduction portion to the motor unit or the rotational driving force transmission mechanism of the motor is located outside the first attachment separate part or the second attachment separate part in the vehicle width direction.
[0166] In this way, the wiring to the motor unit is easily routed. If the motor rotational drive force transmission mechanism is located on the outer side of the first attachment separate part or the second attachment separate part in the vehicle width direction, the rotational drive force transmission mechanism can be easily assembled to the motor unit.
[0167] An eleventh aspect is a saddle-ride type vehicle according to any one of the first to tenth aspects, wherein the mounting position of the motor unit on the attachment is located between the plurality of mounting target portions of the rigid portion.
[0168] This makes it difficult for deformation of the main frame to directly affect the motor unit.
[0169] A twelfth aspect is the saddle-ride type vehicle according to any one of the first to eleventh aspects, wherein the attachment includes a pivot support portion that supports a swing arm so that the swing arm can swing.
[0170] This allows the attachment with the swing arm to be attached to the main frame.
[0171] The attachment according to the thirteenth aspect comprises a plurality of mounting portions each attached to a main frame of a saddle-ride type vehicle, a rigid portion connecting the plurality of mounting portions, and a motor mounting portion to which a motor unit including a motor is attached.
[0172] In this case, the motor unit is attached to the main frame via an attachment. Therefore, by changing the shape of the attachment or by using or not using an attachment, different types of motor units can be mounted on a saddle-ride type vehicle. When an attachment is used, the main frame is reinforced by the rigid part of the attachment. This makes it easy to ensure the rigidity of the saddle-ride type vehicle.
[0173] Furthermore, a fourteenth aspect is a method for manufacturing a saddle-ride type vehicle in which a motor unit including a motor is supported by a main frame including an attachment target portion, and includes preparing multiple types of motor units, preparing multiple types of attachments for attaching the multiple types of motor units to the main frame, selecting the type of attachment depending on the type of motor unit to be supported from the multiple types of motor units, and attaching the motor unit of the type to be supported to the main frame.
[0174] This allows different types of motor units to be mounted on a saddle-ride type vehicle by changing the type of attachment without making major changes to the main frame.
[0175] The above description is illustrative in all respects and is not intended to limit the scope of the present invention. It is understood that numerous variations not illustrated can be envisaged without departing from the scope of the present invention. [Explanation of symbols]
