Summary of the Invention

Problems to be Solved by the Invention

[0004] As described in Patent Document 1, in a saddle-riding type vehicle, the ABS modulator is often provided at the front end of the vehicle body frame. This is because, in a saddle-riding type vehicle where layout constraints are likely to occur, by providing the ABS modulator at the front end of the vehicle body frame, the front end of the vehicle body frame can be effectively utilized as an equipment mounting space. However, since the front end of the vehicle body frame is likely to be immediately behind the front wheel, it is also a position where rainwater, mud, etc. are likely to splash. Therefore, when the ABS modulator is arranged at the front end of the vehicle body frame, it is likely that the fluid pipe connection part, which is a non-electric and non-electronic part, is arranged forward, and the electrical wiring connection part is arranged behind the fluid pipe connection part, making it difficult to have freedom in arranging the ABS modulator. The present invention has been made in view of the above circumstances, and an object thereof is to provide a saddle-riding type vehicle that can provide freedom in arranging the ABS modulator when the ABS modulator is provided at the front end of the vehicle body frame.

Means for Solving the Problem

[0005] A straddle-type vehicle includes a vehicle body frame having a head pipe and a monocross frame extending rearward from the head pipe, and an ABS modulator attached to the front end of the vehicle body frame. In the straddle-type vehicle, a modulator stay that supports the ABS modulator, and a modulator cover that is supported by the modulator stay and covers the ABS modulator are provided. The modulator stay is fastened to the front end of the vehicle body frame behind the head pipe to support the ABS modulator such that the electrical wiring connection part faces forward and the fluid pipe connection part faces rearward. The modulator cover overlaps a part of the electrical wiring connection part of the ABS modulator in a front view, side view, top view, and bottom view of the vehicle body.

Advantageous Effects of the Invention

[0006] A straddle-type vehicle can be provided that has a degree of freedom in arranging an ABS modulator when the ABS modulator is provided at the front end of the vehicle body frame.

[0044] A modulator cover 150 is supported by the modulator stay 120. The modulator cover 150 has a front portion 151 that covers the ABS modulator 110 from the front. An inner side surface portion 152 extending rearward is formed on the inner side in the vehicle width direction of the front portion 151. An outer side surface portion 153 extending rearward is formed on the outer side in the vehicle width direction of the front portion 151. The outer side surface portion 153 extends rearward further than the inner side surface portion 152. An upper surface portion 154 extending from the upper end of the front portion 151 is formed above the outer side surface portion 153. The upper surface portion 154 is formed such that the inner end in the vehicle width direction inclines outward in the vehicle width direction as it goes rearward, and the left - right width becomes narrower (see FIG. 10). A lower surface portion 155 extending from the lower end of the front portion 151 is formed below the outer side surface portion 153. The lower surface portion 155 is formed such that the inner end in the vehicle width direction inclines outward in the vehicle width direction as it goes rearward, and the left - right width becomes narrower (see FIG. 13). The lower surface portion 155 extends rearward further than the upper surface portion 154.

[0045] The front portion 151 is formed so as to curve rearward as it proceeds from the outer side surface portion 153 toward the inner side surface portion 152 (see FIG. 10). Thereby, compared with the case where the front portion 151 is flat, the running wind resistance can be suppressed. On the upper part of the outer side surface portion 153, a convex portion 156 protruding outward in the vehicle width direction more than the outer side surface portion 153 is formed. The convex portion 156 has a cover shape that is recessed and protrudes from the inner side in the vehicle width direction to the outer side in the vehicle width direction. The convex portion 156 extends in the front - rear direction. At the rear end portion of the outer side surface portion 153, a fixing hole 153a penetrating in the thickness direction is formed. At the front portion of the lower surface portion 155, a fixing portion 155a having a fixing hole penetrating in the thickness direction (see FIG. 13) is formed.

[0046] FIG. 9 is a perspective view of the ABS modulator support structure 100 seen from the left rear. FIG. 10 is a plan view of the vehicle body of the ABS modulator support structure 100. Next, an example of the assembling method of the ABS modulator support structure 100 will be described. In FIGS. 7 to 10, grommets (rubbers) 173, 171, 172 are attached to the rubber attachment holes 141a, 146a, 144a of the bottom surface portion 141, the inner side surface portion 142, and the rear surface portion 144 of the outer stay 140, respectively.

[0047] When grommets 173, 171, and 172 are attached, the inner stay 130 is disposed on the grommets 171 to 173 of the outer stay 140. Then, a bolt (fastening member) 161 is inserted into the grommet 171 on the inner side surface portion 142 of the outer stay 140 from the inner side in the vehicle width direction and fastened to the fastening portion 131a on the inner side surface portion 131 of the inner stay 130. Thereby, the inner stay 130 is temporarily fixed to the outer stay 140.

[0048] When the inner stay 130 is temporarily fixed to the outer stay 140, the ABS modulator 110 is disposed on the inner stay 130. Then, a bolt 162 is inserted into the grommet 172 on the rear surface portion 144 of the outer stay 140 from the rear, and the bolt 162 passes through the insertion hole 133a on the rear surface portion 133 of the inner stay 130 and is fastened to the rear surface fastening portion 112b (see FIG. 8) of the ABS modulator 110.

[0049] Also, a bolt 163 is inserted into the grommet 173 on the bottom surface portion 141 of the outer stay 140 from below, and the bolt 163 passes through the insertion hole 132a on the bottom surface portion 132 of the inner stay 130 and is fastened to the bottom surface fastening portion 112a (see FIG. 8) of the ABS modulator 110.

[0050] Thereby, the ABS modulator 110 is fixed to the outer stay 140 via the inner stay 130. At this time, since the grommets 171 to 173 are sandwiched between the inner stay 130 and the outer stay 140, it is difficult for vibrations from the outer stay 140 to be transmitted to the inner stay 130, and it is also difficult for vibrations to be transmitted to the ABS modulator 110 supported by the inner stay 130.

[0051] With the ABS modulator 110 fixed to the modulator stay 120, the modulator stay 120 is fixed to the vehicle body frame 11. That is, the tip 148 of the inner side surface portion 142 of the modulator stay 120 abuts against the right surface of the gusset 35. Also, the lower frame connection portion 145 abuts against a stay 36 (see FIG. 4) protruding rightward from the right surface of the down frame 33 from the rear.

[0052] Then, a bolt 160 is inserted into the fixing hole 148a of the tip 148 from the outside (right side) in the vehicle width direction, and the bolt 160 is fastened to the fastening portion of the gusset 35. Also, a pair of left and right bolts 166 are inserted from the front lower side of the stay 36, and each bolt 166 is fastened to the fastening portion 145c of the lower frame connection portion 145. Thereby, the ABS modulator 110 is attached to the vehicle body frame 11. Incidentally, at this time, the tip 148 overlaps the fuel tank 29 in a side view of the vehicle body (see FIG. 5).

[0053] FIG. 11 is a top view of the vehicle body of the ABS modulator support structure 100 showing a state in which an input brake hose 81, an output brake hose 86, and an electric harness 95 are connected to the ABS modulator 110. FIG. 12 is a front view of the vehicle body of the ABS modulator support structure 100 showing a state in which an input brake hose 81, an output brake hose 86, and an electric harness 95 are connected to the ABS modulator 110. FIG. 13 is a bottom view of the vehicle body of the ABS modulator support structure 100 showing a state in which an input brake hose 81, an output brake hose 86, and an electric harness 95 are connected to the ABS modulator 110.

[0054] The input brake hose 81 is connected to the input pipe connection portion 113 of the ABS modulator 110 via a metal joint portion 84. Also, the output brake hose 86 is connected to the output pipe connection portion 114 of the ABS modulator 110 via a metal joint portion 85. The brake piping system 80 (see Fig. 11) of the present embodiment is constituted by an input brake hose 81, a joint portion 84, a joint portion 85, and an output brake hose 86.

[0055] A sensor cable 90 is locked to the output brake hose 86 via a clamp 91. The sensor cable 90 is routed in parallel with the output brake hose 86 between the front wheel 13 and the ABS modulator 110. When the sensor cable 90 passes through the clamp 91 closest to the ABS modulator 110, it is routed upward on the inner side in the vehicle width direction and clamped by a clamp member 92 locked to the inclined portion 147 of the outer stay 140. The clamp member 92 is supported by inserting a locking claw 92a (see Fig. 12) into a claw hole 147a (see Fig. 7) of the inclined portion 147. The sensor cable 90 extends toward the inner side in the vehicle width direction and is electrically connected to an ECU (Electronic Control Unit) (not shown).

[0056] An electric harness (electrical wiring) 95 extends from this ECU and is electrically connected to the ABS modulator 110. That is, a connector 96 of the electric harness 95 is connected to a connector portion 115 of the ABS modulator 110. The connector 96 is formed with an outer peripheral shape larger than that of the connector portion 115, and is mounted so as to cover the connector portion 115. Thereby, the ABS modulator 110 and the electric harness 95 are electrically connected. The electric harness 95 is bent upward in a U shape (see Fig. 12) toward the inner side in the vehicle width direction from the connector 96 and is routed on the outer side in the vehicle width direction. The electric harness 95 routed on the outer side in the vehicle width direction is wound and held by a band 97 on the outer peripheral side of the connector 96.

[0057] When the electrical harness 95 extends beyond the outside in the vehicle width direction above the connector 96, it is routed rearward along the inner side in the vehicle width direction of the outer side surface portion 143 of the outer stay 140 (see Fig. 11). At this time, the electrical harness 95 is clamped by a clamp member (wiring support portion) 98 locked to the outer side surface portion 143. The insertion claw (insertion end) 98a of the clamp member 98 (see Fig. 11) is inserted and supported from the inner side in the vehicle width direction into the claw hole 143a of the outer side surface portion 143 (see Fig. 7).

[0058] When the electrical harness 95 extends beyond the outer side surface portion 143 of the outer stay 140 rearward, it is routed inward in the vehicle width direction, extends inward in the vehicle width direction, and is connected to an ECU (not shown). At this time, the electrical harness 95 is clamped by a clamp member 99 locked to the rear surface portion 144 of the outer stay 140. The insertion claw 99a of the clamp member 99 (see Fig. 13) is inserted and supported from above into the claw hole 144c of the bent portion 144b of the rear surface portion 144 (see Fig. 7).

[0059] In this state, the modulator cover 150 is attached. For the modulator cover 150, a bolt 164 is inserted from the outside in the vehicle width direction into the fixing hole 153a of the outer side surface portion 153, and the bolt 164 is fastened to the cover support hole 143b of the outer side surface portion 143 of the outer stay 140. Also, a bolt 165 is inserted from below into the fixing portion 155a of the lower surface portion 155, and the bolt 165 is fastened to the cover support hole 141b of the bottom surface portion 141 of the outer stay 140. Thereby, the modulator cover 150 is attached to the modulator stay 120. At this time, since a convex portion 156 protruding in a direction away from the insertion claw 98a (see Fig. 11) is formed on the modulator cover 150, it can be attached without interfering with the insertion claw 98a of the clamp member 98.

[0060] Here, when the modulator cover 150 covers the ABS modulator 110, it covers at least a part of the connector portion 115 in any of the top view of the vehicle body (see FIG. 11), front view of the vehicle body (see FIG. 12), side view of the vehicle body (see FIG. 5), and bottom view of the vehicle body (see FIG. 13). Therefore, even if rainwater or mud splashed by the front wheel 13 is directed towards the ABS modulator 110, the modulator cover 150 makes it easier to protect the connector portion 115 from rainwater and mud. In particular, since the connector 96 of the electrical harness 95 is mounted so as to cover the connector portion 115, the gap between the connector 96 and the connector portion 115 at the time of connection is located on the outer side in the vehicle width direction. For this reason, the modulator cover 150 having a structure that covers from the outer side in the vehicle width direction can efficiently prevent water and mud from entering the connector portion 115. Further, since the upper surface portion 154 overlaps a part of the connector portion 115 (see FIG. 10), it is easier to bend the electrical harness 95 into a U shape.

[0061] Also, as shown in FIG. 13, the pressure adjustment hole 110a of the ABS modulator 110 is covered by the bottom surface portion 141 of the outer stay 140 from below and the lower surface portion 155 of the modulator cover 150. Therefore, since it is covered from below in a double structure, it is difficult for water and mud splashed from the front wheel 13 to enter the pressure adjustment hole 110a. In particular, the pressure adjustment hole 110a is in a state of being separated from the outer stay 140 by the inner stay 130, and air can easily enter and exit.

[0062] Here, in the steering system 50, since the front fork 14 expands and contracts while being steered, the brake pipe system 80 straddling between the steering system 50 and the vehicle body frame 11 is routed and regulated so that the contact width and movement width are within a predetermined range during travel. In the present embodiment, the modulator cover 150, together with the shroud cover 72, can protect the ABS modulator 110 from rainwater, mud, etc. The ABS modulator 110 can be arranged with the connector portion 115 facing forward and the input pipe connection portion 113 and the output pipe connection portion 114 facing rearward, creating a margin for regulating the brake hoses 81 and 86 during steering and making it easier to have freedom in arranging the ABS modulator 110.

[0063] Therefore, when the ABS modulator 110 is provided at the front end portion of the vehicle body frame 11, it is possible to have freedom in arranging the ABS modulator 110. In particular, in the present embodiment, the front fender 26 is an off-road saddle-type vehicle 10 where the front wheel 13 is greatly separated, the expansion and contraction of the front fork 14 is likely to be large, and water and mud from the front wheel 13 are likely to be deflected to the front end portion of the vehicle body frame 11. Moreover, the fuel tank 29 is arranged below the main frame 31, the ABS modulator 110 is likely to be located below, and restrictions are likely to occur in regulating the brake hoses 81 and 86. In contrast, in the present embodiment, the modulator cover 150 can preferably provide the ABS modulator 110 at the front end portion of the vehicle body frame 11.

[0064] As described above, according to the present embodiment to which the present invention is applied, in the saddle-riding type vehicle 10 including the vehicle body frame 11 having the head pipe 18 and the main frame 31 extending rearward from the head pipe 18, and the ABS modulator 110 attached to the front end portion of the vehicle body frame 11, a modulator stay 120 that supports the ABS modulator 110 and a modulator cover 150 that is supported by the modulator stay 120 and covers the ABS modulator 110 are provided. The modulator stay 120 is fastened to the front end portion of the vehicle body frame 11 behind the head pipe 18, thereby supporting the ABS modulator 110 such that the connector portion 115 faces forward and the input pipe connection portion 113 and the output pipe connection portion 114 face rearward. The modulator cover 150 overlaps a part of the connector portion 115 of the ABS modulator 110 in a front view of the vehicle body, a side view of the vehicle body, a top view of the vehicle body, and a bottom view of the vehicle body.

[0065] According to this configuration, even if the ABS modulator 110 is arranged at the front end portion of the vehicle body frame 11 such that the connector portion 115 faces forward, the modulator cover 150 can protect the connector portion 115 from mud, water, etc. that the front wheel 13 picks up during traveling, and an improvement in the aerodynamic surface can also be expected, enhancing the traveling stability. Therefore, it becomes possible to arrange the ABS modulator 110 such that the input pipe connection portion 113 and the output pipe connection portion 114 face rearward, creating a margin for regulating the brake hoses 81 and 86 during steering and making it easier to have freedom in arranging the ABS modulator 110. Therefore, it is possible to provide a saddle-riding type vehicle 10 that can have a degree of freedom in layout when arranging the ABS modulator 110 when the ABS modulator 110 is provided at the front end portion of the vehicle body frame 11.

[0066] In the present embodiment, the ABS modulator 110 is arranged such that the connector portion 115 faces inward in the vehicle body width direction. According to this configuration, since the electrical harness 95 extending from the connector portion 115 is easily routed inside the vehicle width direction, it is possible to suppress the modulator cover 150 covering the connector portion 115 from bulging outward in the vehicle width direction.

[0067] Also, in the present embodiment, the ABS modulator 110 is arranged such that the input pipe connection portion 113 and the output pipe connection portion 114 face upward in the vehicle vertical direction. According to this configuration, since the input pipe connection portion 113 and the output pipe connection portion 114 face upward and rearward, it is easy to connect the brake hoses 81, 86 from above, and a margin can be provided for regulating the brake hoses 81, 86 during steering.

[0068] Also, in the present embodiment, the modulator cover 150 and the modulator stay 120 are fastened on the side surface and the bottom surface. According to this configuration, since they are fastened on a plurality of surfaces facing different directions, the fastening rigidity between the modulator cover 150 and the modulator stay 120 can be improved with a minimum number of fastening points.

[0069] Also, in the present embodiment, the modulator stay 120 is composed of an outer stay 140 and an inner stay 130 supported inside the outer stay 140. On the bottom surface and the rear surface, the outer stay 140, the inner stay 130, and the ABS modulator 110 are fastened with grommets 172, 173 disposed, and on the side surface, the outer stay 140 and the inner stay 130 are fastened with the grommet 171 disposed. According to this configuration, since the inner stay 130 is disposed between the outer stay 140 and the ABS modulator 110, and the grommets 171, 172, 173 are disposed at each fastening point, it is possible to make it difficult for the vibration of the vehicle body during traveling to be transmitted to the ABS modulator 110.

[0070] In the present embodiment, an electrical harness 95 connected to the connector portion 115 and a clamp member 98 that is inserted into the outer stay 140 of the modulator stage 120 and supports the electrical harness 95 are provided. On the side surface of the modulator cover 150, a convex portion 156 that protrudes while being recessed in a direction away from the insertion claw 98a of the clamp member 98 is provided. According to this configuration, the clamp member 98 can be sufficiently inserted into the outer stay 140 while avoiding interference with the modulator cover 150, the electrical harness 95 extending from the ABS modulator 110 can be firmly supported, and the electrical harness 95 can be efficiently accommodated in the modulator cover 150 in terms of space.
