Description

The present invention relates to a saddle-type vehicle.

For example, Patent Document 1 discloses a saddle-type vehicle in which the steering shaft at the front of the vehicle body is covered with a front cover, a battery is placed in the internal space of the front cover, and a harness is routed in front of the battery.

Patent No. 3321673

However, the above-mentioned conventional technology does not disclose any scheme for consolidating and arranging the brake cable, which moves when the steering wheel is turned, and the vehicle body side harness, which does not move when the steering wheel is turned, on one side in the vehicle width direction in order to secure space for arranging a storage box inside the vehicle front cover.

The present invention aims to make effective use of the internal space of a saddle-type vehicle in which the steering shaft at the front of the vehicle body is covered with a front body cover by consolidating and arranging the rotating and non-rotating cord-like members inside the front body cover.

As a means for solving the above problem, a first aspect of the present invention is a saddle-type vehicle (1) in which a steering wheel (2) is supported on a vehicle body (22) so as to be rotatable about a steering shaft (23), and the periphery of the steering shaft (23) is covered with a vehicle body front cover (16), the vehicle body front cover (16) comprising: a first functional part (31) supported on the steering wheel (2) and rotating integrally with the steering wheel (2); a first cord-like member (33) connected to the first functional part (31); a second functional part (35) supported on the vehicle body (22) without rotating integrally with the steering wheel (2); and a second rope-like member (37) connected to a functional part (35), wherein the first rope-like member (33) and the second rope-like member (37) are arranged within an internal space (K2) formed inside the vehicle front cover (16), the vehicle body (22) is provided with a plurality of fixing portions (41-44) for fixing an intermediate portion of the second rope-like member (37), and a range (H1) of the second rope-like member (37) fixed to the plurality of fixing portions (41-44) is arranged radially outward from a region (R1) in which the first rope-like member (33) rotates around the steering shaft (23).
According to this configuration, the second rope-like member fixed to the vehicle body is disposed radially outward of the rotational range of the first rope-like member that rotates together with the steering wheel, so that the first rope-like member and the second rope-like member can be disposed compactly without interfering with each other in the limited space inside the vehicle front cover. This makes it easier to secure space for arranging other components inside the vehicle front cover, and makes it possible to effectively utilize the internal space of the vehicle front cover while keeping it compact.
In addition, by positioning the first rope-like member, which rotates together with the steering wheel, closer to the steering axis than the second rope-like member, the rotation area of the first rope-like member is reduced, making it easier to secure space for arranging electrical components and other components such as storage boxes, and enabling more effective utilization of the internal space of the vehicle front cover.
In addition, it becomes easier to arrange the first rope-like member and the second rope-like member together on one side of the vehicle width, allowing the space on the other side of the vehicle width to be effectively utilized as space for arranging a storage box, etc., and increasing the capacity of the storage box.

A second aspect of the present invention is that in the first aspect described above, the second functional component (35) includes a first vehicle body side electrical component (35b) arranged on one side of the vehicle width direction of the steering shaft (23) within the internal space (K2) of the vehicle body front cover (16), the second rope-like member (37) includes a first harness (37a3) connected to the first vehicle body side electrical component (35b), and in a range (H1) fixed to the multiple fixing portions (41 to 44) of the second rope-like member (37), the first harness (37a3) is arranged outer than the first vehicle body side electrical component (35b) in a radial direction centered on the steering shaft (23).
According to this configuration, by arranging the cord-like member (harness), which has a higher degree of freedom in shape than electrical components whose shapes are fixed, outside the electrical components in the radial direction of the steering shaft center, the electrical components whose shapes are fixed can be accommodated within the arrangement space on the radially inner side, while the harness, which has a higher degree of freedom in shape, can be arranged on the radially outer side and arranged along the vicinity of the vehicle front cover. This makes it possible to efficiently utilize the internal space of the vehicle front cover, which has limited space, while increasing the degree of freedom in design of the vehicle front cover.
In addition, by positioning the first harness radially outward of the first vehicle body side electrical component, which is biased to one side in the vehicle width direction within the vehicle body front cover, the harness can be retracted from the other side in the vehicle width direction, and the other side in the vehicle width direction within the vehicle body front cover can be effectively used as space for positioning other components.

A third aspect of the present invention is directed to the second aspect, in which the first cord-like member (33) is arranged radially inwardly of the first vehicle body side electrical component (35b) centered on the steering shaft (23).
According to this configuration, the first rope-like member, which is a steering component, is positioned radially inward from the electrical components around the center of the steering shaft, so that the first rope-like member and the second rope-like member (first harness) are spaced apart radially between the electrical components, making it easier to suppress interference between the rope-like members.

A fourth aspect of the present invention is that, in the above-mentioned second or third aspect, the vehicle body front cover (16) comprises a front cover (11a) covering the vehicle front side of the steering shaft (23) and a rear cover (11b) covering the vehicle rear side of the steering shaft (23), and in the range (H1) fixed to the multiple fixing portions (41-44) of the second rope-like member (37), the first harness (37a3) is arranged between the first vehicle body side electrical component (35b) and the front cover (11a).
With this configuration, while the vehicle body frame etc. is located behind the steering shaft, it is easier to secure space for arranging components on the front side of the steering shaft, so the gap between the first vehicle body side electrical component and the front cover can be effectively utilized. As a whole, by utilizing this area and arranging the first harness between the first vehicle body side electrical component and the front cover, the internal space of the vehicle body front cover can be made compact while being efficiently utilized.

A fifth aspect of the present invention is any one of the second to fourth aspects, wherein the vehicle body front cover (16) includes a front cover (11a) that covers a vehicle front side of the steering shaft (23) and a rear cover (11b) that covers a vehicle rear side of the steering shaft (23), and the second functional component (35) includes a second vehicle body side electrical component (35a) that is arranged between the steering shaft (23) and the front cover (11a) in an internal space (K2) of the vehicle body front cover (16), and the second functional component (35) includes a second vehicle body side electrical component (35a) that is arranged between the steering shaft (23) and the front cover (11a), and The second harness (37a1, 37a2) is connected to the second vehicle body side electrical component (35a), and in a range (H1) where the second harness (37a1, 37a2) is fixed to the multiple fixing portions (41-44) of the second rope-shaped member (37), the second harness (37a1, 37a2) is arranged on the vehicle forward side of the second vehicle body side electrical component (35a), and at least one of the multiple fixing portions (41-44) is fixed to a support member (39) that supports the second vehicle body side electrical component (35a).
According to this configuration, the electrical components with fixed shapes are arranged in a forward position relatively close to the steering shaft, while the harness with high degree of freedom in shape is arranged further forward of the electrical components and arranged along the vicinity of the vehicle body front cover. This increases the degree of freedom in design of the vehicle body front cover while efficiently utilizing the limited internal space of the vehicle body front cover. The second harness connected to the second vehicle body side electrical component is arranged at a distance from the second vehicle body side electrical component to the front of the vehicle, and is fixed to the support member immediately adjacent to the second vehicle body side electrical component, so that the second harness can be stably connected to the second vehicle body side electrical component.

A sixth aspect of the present invention is a vehicle according to any one of the second to fifth aspects, wherein the second functional component (35) is provided with a third vehicle-body side electrical component (35c) that is disposed on one side of the steering shaft (23) in the vehicle width direction in the internal space (K2) of the vehicle-body front cover (16) and that is disposed rearward of the first vehicle-body side electrical component (35b); and among the plurality of fixing portions (41 to 44), the third vehicle-body side electrical component (35c) is disposed radially outward of a region (R1) of the second rope-like member (37) in which the first rope-like member (33) rotates. A first fixed portion (41), which is the starting point of a range (H1) in which the electric component (35c) is placed, is positioned above the third vehicle-body side electrical component (35c) in a side view of the vehicle, the second rope-like member (37) is arranged to extend upward from the vicinity of the steering shaft (23) toward the first fixed portion (41), and extends downward and toward the front of the vehicle after passing through the first fixed portion (41), and the third vehicle-body side electrical component (35c) and the first fixed portion (41) at least partially overlap each other in a top view of the vehicle.
According to this configuration, the second rope-like member is routed up to one end near the steering shaft, and then routed downward in a range after passing through the first fixing part (a range in which the first rope-like member is arranged radially outward from the area in which the first rope-like member rotates). In this way, the second rope-like member is routed while avoiding the third body side electrical component in the vertical direction, making it easier to provide a space for arranging the third body side electrical component, thereby making effective use of the internal space of the vehicle front cover and increasing the degree of freedom in the connector direction of the harness of the third body side electrical component.

According to the present invention, in a saddle-type vehicle in which the steering shaft at the front of the vehicle body is covered with a front body cover, the rotating and non-rotating cord-like members can be concentrated and arranged inside the front body cover to effectively utilize the internal space.

<Harness>
The motorcycle 1 includes a harness 38 connected to various electrical components. The harness 38 includes a plurality of sub-harnesses (handle-side branch harness 33b, vehicle-side branch harness 37a) connected to each of the electrical components, and a main harness section 38a bundling the sub-harnesses 33b, 37a. The main harness section 38a extends from the front to the rear of the vehicle body. The main harness section 38a extends forward inside the floor step 6, and then extends upward along the rear surface of the down frame 21b. The main harness section 38a extends vertically between the inner cover 11b and the main frame (down frame 21b).

The electrical components arranged in various parts of the motorcycle 1 are electrically connected to each other via a harness 38. The harness 38 is made by bundling together multiple wires (electrical cables) that supply power from the battery 35a, which is the on-board power source, to the electrical components in each part of the vehicle, and attaching connectors to the ends of each wire.

The main harness section 38a, which extends upward behind the down frame 21b, reaches a branching point 38b near the rear surface of the head pipe 21a, and then branches into multiple branch harnesses 33b, 37a. The multiple branch harnesses 33b, 37a are divided into multiple vehicle body side branch harnesses 37a connected to vehicle body side electrical components, and multiple handle side branch harnesses 33b connected to handle side electrical components 31b. The branching point is located in a position that overlaps with the ECU 35c in a side view of the vehicle.

The multiple vehicle body side branch harnesses 37a are appropriately bundled downstream of the branch point 38b in the path from the main harness section 38a toward the vehicle body side electrical components. The multiple vehicle body side branch harnesses 37a branch off at suitable positions downstream of the branch point 38b and extend toward the target components.

The multiple vehicle body side branch harnesses 37a extend upward from the branch point 38b and curve toward the outside (right side) and downward in the vehicle width direction at a height above the ECU 35c. The multiple vehicle body side branch harnesses 37a are routed in an area forward of the steering shaft 23 and connected to corresponding vehicle body side electrical components.

The multiple vehicle body side branch harnesses 37a include a positive harness 37a1 and a negative harness 37a2 that are respectively connected to the positive and negative terminals of the battery 35a, a fuse harness 37a3 that is connected to the fuse box 35b, a control harness 37a4 that is connected to the ECU 35c, left and right turn signal harnesses 37a5 and 37a6 that are respectively connected to the left and right turn signals, a switch harness 37a7 that is connected to the main switch 29, and an accessory harness 37a8 that is connected to an accessory component such as a USB port.

The vehicle body side branch harnesses 37a are held (fixed) at multiple locations on the vehicle body main body 22 side at intermediate portions (not limited to the center) in the longitudinal direction downstream of the branch point 38b. The vehicle body side branch harnesses 37a are held (fixed) at multiple locations on the vehicle body main body 22 parts by annular clips 41a to 44a downstream of the branch point 38b.

Specifically, the multiple vehicle body side branch harnesses 37a are first held by the front body cover 16 or the like via a first clip 41a near the top of the ECU 35c. Next, the multiple vehicle body side branch harnesses 37a run from the outer side of the fuse box 35b in the vehicle width direction (right side of the vehicle body) to the front lower side of the fuse box 35b, curve inward in the vehicle width direction, pass in front of the battery 35a, reach the left side of the vehicle body, and are then held by the front left side of the battery case 39 via a second clip 42a.

Next, the multiple vehicle body side branch harnesses 37a extend and curve upward to the left of the battery 35a, and are held by the front body cover 16 or the like via a third clip 43a at a height above the battery 35a. The multiple vehicle body side branch harnesses 37a are held by the front body cover 16 or the like via a fourth clip 44a at a position where they curve inward in the vehicle width direction in front of and below the fuse box 35b. A right holding portion 39d that holds the bundle of vehicle body side branch harnesses 37a is provided on the front right side of the battery case 39, and a central holding portion 39e that holds the bundle of vehicle body side branch harnesses 37a and the connector of the spare accessory harness 37a8 is provided in the center of the left and right front of the battery case 39.

When the multiple vehicle body side branch harnesses 37a extend outside (right side) of the fuse box 35b in the vehicle width direction, they branch off the right indicator harness 37a6 (including the spare harness), the control harness 37a4, and the fuse harness 37a3. When the multiple vehicle body side branch harnesses 37a extend in front of the battery 35a, they branch off the positive and negative electrode harnesses 37a1, 37a2, and the spare accessory harness 37a9 (dummy harness). When the multiple vehicle body side branch harnesses 37a extend upward on the left side of the battery 35a, they branch off the left indicator harness 37a5 (including the spare harness) and the accessory harness 37a8. The multiple vehicle body side branch harnesses 37a branch off the switch harness 37a7 from the branch point 38b.

The multiple handlebar side branch harnesses 33b branch off from a branch point 38b separately from the vehicle body side branch harness 37a. The multiple handlebar side branch harnesses 33b extend upward near the head pipe 21a, reach inside the handlebar cover 2b, and are connected to the handlebar side electrical components 31b.

The multiple vehicle body side branch harnesses 37a are fixed to the vehicle body 22 at multiple points in the middle of their length.
In the figure, reference numeral 41 indicates a first fixing portion that fixes the vehicle body side branch harness 37a using a first clip 41a, reference numeral 42 indicates a second fixing portion that fixes the vehicle body side branch harness 37a using a second clip 42a, reference numeral 43 indicates a third fixing portion that fixes the vehicle body side branch harness 37a using a third clip 43a, and reference numeral 44 indicates a fourth fixing portion that fixes the vehicle body side branch harness 37a using a fourth clip 44a.

Referring to FIG. 4, the range H1 of the vehicle body side branch harness 37a that is fixed to the multiple fixing parts 41-44 (the range H1 from the first fixing part 41 on the most upstream side to the third fixing part 43 on the most downstream side) is held (fixed) on the vehicle body main body 22 side. This range H1 is located radially outward of the region R1 in which the first rope-like member 33 rotates around the steering shaft 23. Region R1 is particularly defined by the rotation region of the brake hose 33a. The rotation region of the handle side branch harness 33b is contained inside region R1.

The vehicle body side branch harness 37a extends from the right side of the internal space K2 of the front body cover 16 in a curved manner toward the front side downstream of the branch point 38b, and is connected to the vehicle body side electrical components. In addition to the vehicle body side branch harness 37a, the brake hose 33a is arranged on the right side of the internal space K2 of the front body cover 16. However, the region R1 in which the brake hose 33a rotates around the steering shaft 23 is provided on the inner periphery side of the range H1 in which the path of the vehicle body side branch harness 37a is fixed by the multiple fixing parts 41 to 44. This prevents the vehicle body side branch harness 37a and the brake hose 33a from interfering with each other while arranging them together on the right side of the vehicle body. In addition, since the vehicle body side branch harness 37a and the brake hose 33a are arranged together on the right side of the vehicle body, a large space can be secured for arranging a storage box on the left side of the vehicle body.
In addition, in Figure 4, the switch harness 37a7 is located more inward than the arc indicating the region R1. However, at the vertical height at which the switch harness 37a7 is arranged, the brake hose 33a is positioned close to the steering shaft 23 and rotates more inward than the switch harness 37a7, so there is no interference between the brake hose 33a and the switch harness 37a7.

As described above, the motorcycle 1 in the above embodiment is a saddle-ride type vehicle in which the steering wheel 2 is supported on the vehicle body 22 so as to be rotatable around the steering shaft 23, and the periphery of the steering shaft 23 is covered with a vehicle front cover (front body cover 16). The motorcycle 1 includes a first functional part 31 (right brake lever 31a, handle-side electrical parts 31b) supported on the steering wheel 2 and rotating integrally with the steering wheel 2, a first rope-like member 33 (brake hose 33a, handle-side branch harness 33b) connected to the first functional part 31, a second functional part 35 (battery 35a, fuse box 35b, ECU 35c) supported on the vehicle body 22 without rotating integrally with the steering wheel 2, and a second rope-like member 37 (vehicle-side branch harness 37a) connected to the second functional part 35. The first rope member 33 and the second rope member 37 are disposed within an internal space K2 formed inside the vehicle front cover. The vehicle body 22 is provided with a plurality of fixing parts 41-44 that fix the middle part of the second rope member 37. The range H1 of the second rope member 37 that is fixed to the plurality of fixing parts 41-44 is disposed radially outward of the region R1 in which the first rope member 33 rotates around the steering shaft 23.

According to this configuration, the second rope-like member 37 fixed to the vehicle body 22 is disposed radially outward of the rotation region R1 of the first rope-like member 33 that rotates together with the steering wheel 2, so that the first rope-like member 33 and the second rope-like member 37 can be disposed compactly without interfering with each other in the internal space K2 of the vehicle body front cover, which has limited space. This makes it easier to ensure space for arranging other components within the vehicle body front cover, and the internal space K2 of the vehicle body front cover can be effectively utilized while being made compact.
In addition, by positioning the first rope-like member 33, which rotates together with the steering wheel 2, closer to the steering axis 23 than the second rope-like member 37, the rotation area R1 of the first rope-like member 33 is smaller, making it easier to secure space for arranging electrical components and other components such as storage boxes, and enabling more effective use of the internal space K2 of the vehicle front cover.
In addition, it becomes easier to arrange the first rope-like member 33 and the second rope-like member 37 together on one side of the vehicle width direction, allowing the space on the other side of the vehicle width direction to be effectively utilized as space for arranging a storage box, etc., and also enabling the capacity of the storage box to be increased.

In addition, in the above motorcycle 1, the second functional component 35 includes a first vehicle body side electrical component (fuse box 35b) arranged on one side of the steering shaft 23 in the vehicle width direction within the internal space K2 of the vehicle body front cover, and the second rope-like member 37 includes a first harness (fuse harness 37a3) connected to the first vehicle body side electrical component, and in the range H1 fixed to the multiple fixing portions 41 to 44 of the second rope-like member 37, the first harness is arranged outer than the first vehicle body side electrical component in the radial direction centered on the steering shaft 23.
According to this configuration, the cord-like member (harness), which has a higher degree of freedom in shape than electrical components whose shapes are fixed, is arranged outside the electrical components in the radial direction of the center of the steering shaft 23, so that the electrical components whose shapes are fixed are accommodated within the arrangement space on the radially inner side, while the harness, which has a higher degree of freedom in shape, can be arranged on the radially outer side and arranged along the vicinity of the vehicle body front cover. Therefore, the interior space K2 of the vehicle body front cover, which has a limited space, can be efficiently utilized while increasing the degree of freedom in design of the vehicle body front cover.
In addition, by positioning the first harness radially outward of the first vehicle body side electrical component, which is biased to one side in the vehicle width direction within the vehicle body front cover, the harness can be retracted from the other side in the vehicle width direction, and the other side in the vehicle width direction within the vehicle body front cover can be effectively used as space for positioning other components.

In the motorcycle 1, the first rope-like member 33 is disposed radially inward from the first vehicle body side electrical component with the steering shaft 23 as the center.
According to this configuration, the first rope-like member 33, which is a steering component, is positioned radially inward from the center of the steering shaft 23 relative to the first vehicle body side electrical component, so that the first rope-like member 33 and the second rope-like member 37 (first harness) are spaced apart radially between the first vehicle body side electrical component, making it easier to suppress interference between the rope-like members.

In addition, in the above motorcycle 1, the vehicle body front cover includes a front cover (front cover 11a) that covers the vehicle front side of the steering shaft 23, and a rear cover (inner cover 11b) that covers the vehicle rear side of the steering shaft 23, and in the range H1 where the second rope-like member 37 is fixed to the multiple fixing portions 41 to 44, the first harness is arranged between the first vehicle body side electrical component and the front cover.
According to this configuration, while the body frame 21 etc. is present to the rear of the steering shaft 23, space for arranging components can be easily secured on the front side of the steering shaft 23, so that the gap between the first body side electrical component and the front cover can be effectively utilized, and by arranging the first harness between the first body side electrical component and the front cover by utilizing this area as a whole, the internal space K2 of the body front cover can be made compact while being efficiently utilized.

In addition, in the above motorcycle 1, the second functional component 35 includes a second vehicle body side electrical component (battery 35a) that is arranged between the steering shaft 23 and the front cover within the internal space K2 of the vehicle body front cover, the second rope-like member 37 includes a second harness (positive and negative harnesses 37a1, 37a2) that is connected to the second vehicle body side electrical component, and in the range H1 where the second rope-like member 37 is fixed to the multiple fixing portions 41 to 44, the second harness is arranged further forward of the vehicle than the second vehicle body side electrical component, and at least one of the multiple fixing portions 41 to 44 (second fixing portion 42) is fixed to a support member (battery case 39) that supports the second vehicle body side electrical component.
According to this configuration, the electrical components with fixed shapes are arranged in a forward position relatively close to the steering shaft 23, while the harness with high degree of freedom in shape is arranged further forward of the electrical components and arranged along the vicinity of the vehicle body front cover. This allows efficient use of the internal space K2 of the vehicle body front cover, which has limited space, while increasing the degree of freedom in design of the vehicle body front cover. The second harness connected to the second vehicle body side electrical component is fixed to the support member immediately adjacent to the second vehicle body side electrical component while being arranged away from the second vehicle body side electrical component, so that the second harness can be stably connected to the second vehicle body side electrical component.

In addition, in the above motorcycle 1, the second functional component 35 is arranged on one side of the steering shaft 23 in the vehicle width direction (right side) within the internal space K2 of the vehicle body front cover, and is provided with a third vehicle body side electrical component (ECU 35c) arranged rearward of the first vehicle body side electrical component, and among the multiple fixing portions 41 to 44, a first fixing portion 41 which is the starting point of a range H1 of the second rope-like member 37 which is arranged radially outward from a region R1 in which the first rope-like member 33 rotates is arranged above the third vehicle body side electrical component in a side view of the vehicle, the second rope-like member 37 is arranged to extend upward from the vicinity of the steering shaft 23 toward the first fixing portion 41, and extends downward and toward the front side of the vehicle after passing the first fixing portion 41, and in a top view of the vehicle, the third vehicle body side electrical component and the first fixing portion 41 at least partially overlap each other.
According to this configuration, the second rope-like member 37 is routed up to one end near the steering shaft 23, and then routed downward in a range H1 (a range H1 disposed radially outward from the region R1 in which the first rope-like member 33 rotates) after passing through the first fixing portion 41. In this manner, the second rope-like member 37 is routed while avoiding the third vehicle-body side electrical component in the vertical direction, making it easier to provide a space for arranging the third vehicle-body side electrical component, thereby making effective use of the internal space K2 of the vehicle-body front cover and increasing the degree of freedom in the connector direction of the harness of the third vehicle-body side electrical component.
