[0003] [Patent Document 1] Patent No. 5396363 Summary of the Invention [Problem to be solved by the invention]

[0004] The technology described in Patent Document 1 basically detects the operation state of the clutch lever based on the detection results of one clutch switch, so it is only possible to detect whether or not the clutch lever has moved to a predetermined position, and there is not much need for precision in detecting whether the clutch lever has moved to a position other than the predetermined position. However, there are cases where the above detection accuracy is required depending on the vehicle. The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a saddle-ride type vehicle that can accurately detect when the clutch lever has moved between the gripped position and the non-gripped position, with a simple configuration that prevents the layout of components such as sensors from becoming complicated. [Means for solving the problem]

[0005] A saddle-ride type vehicle includes a clutch lever, a swing shaft that swingably supports the clutch lever, a lever pivot on which the swing shaft is mounted, and a first sensor and a second sensor having switches that are pressed by the clutch lever, wherein the first sensor is fixed to one surface of the lever pivot in the swing axis direction, and the second sensor is fixed to the other surface of the lever pivot in the swing axis direction, the switch of the first sensor and the switch of the second sensor are arranged concentrically on either side of the swing shaft when viewed in the axial direction of the swing shaft, and the switch of the first sensor is pressed when the clutch lever is moved to a gripped position, and the switch of the second sensor is pressed when the clutch lever is moved to a non-gripped position. [Effects of the Invention]

[0006] A saddle-type vehicle can be provided that can accurately detect when the clutch lever has moved between the gripped position and the non-gripped position, with a simple configuration that prevents the layout of components such as sensors from becoming complicated.

The lever cover 100 is not shown in Figs. The clutch lever 80 has a rod-shaped lever main body 81 extending in the left-right direction, and a plate-shaped lever base 82 provided on the right side of the lever main body 81. A slot-shaped cable engagement portion 83 is formed at the right end of the lever main body 81. The cable engagement portion 83 allows the inner cable of the clutch cable 132 to be hooked thereon with a retaining mechanism.

[0037] A lever base 82 is formed at the right end of the lever main body 81. The lever base 82 is formed to be thinner than the lever main body 81. The lever base 82 has a stepped recessed shape relative to the lever main body 81. A contact surface 81a extending in the front-to-rear direction is formed at the right end of the lever main body 81. A pair of contact surfaces 81a are formed above and below the lever base 82. The lever base 82 is housed in the lever housing portion 74 of the left lever pivot 70. At this time, the contact surface 81a can come into contact with the right surface of the lever support portion 73 of the left lever pivot 70.

[0038] The lever base 82 is formed with a pivot shaft hole 82a that penetrates in the thickness direction. The pivot shaft hole 82a is formed to correspond to the positions of the pivot shaft holes 73a1, 73b1. A columnar first protrusion 85 that protrudes upward is formed on the handle 21 side of the pivot shaft hole 82a. The first protrusion 85 is formed on the upper surface (one side surface in the pivot shaft direction) of the lever base 82. The first protrusion 85 protrudes upward beyond the lever main body 81. The first protrusion 85 is formed in a position that allows it to enter the first opening 75 of the left lever pivot 70.

[0039] When viewed in the axial direction, a columnar second protrusion 86 that protrudes downward is formed on the opposite side of the first protrusion 85 with the pivot shaft hole 82a (the pivot shaft 112) in between. The second protrusion 86 is formed on the lower surface (the other side in the pivot shaft direction) of the lever base 82. The second protrusion 86 protrudes downward further than the lever main body 81. The second protrusion 86 is formed in a position that allows it to enter the second opening 76 of the left lever pivot 70.

[0040] Between the first protrusion 85 and the pivot hole 82a, a recess 82b extending in the pivot direction and recessed to the left is formed on the right surface of the lever base 82 (see FIG. 10). The recess 82b is formed in accordance with the position of the communication hole 73b2 in the lower surface portion 72b of the left lever pivot 70. When the clutch lever 80 is moved to the disengaged position P1, the recess 82b is prevented from blocking the communication hole 73b2.

[0041] A disengagement detection sensor 91 and an engagement detection sensor 92 that detect the operation state of the clutch lever 80 are attached to the sensor attachment portions 77 and 78 of the left lever pivot 70, respectively. The sensors 91 and 92 have the same shape. In this embodiment, the disengagement detection sensor 91 and the engagement detection sensor 92 are sensors of the same type and standard.

[0042] 5, sensors 91 and 92 each have a substantially rectangular sensor main body 93 that is thick in the vertical direction, a pair of terminals 94 supported by sensor main body 93, and a rod-shaped switch 95 that is supported by sensor main body 93 so as to be able to advance and retreat. Switch 95 is configured to be able to advance and retreat in a direction perpendicular to the direction in which the pair of terminals 94 protrude from sensor main body 93.

[0043] A positioning protrusion 93a that protrudes in the thickness direction is formed on the sensor main body 93. The positioning protrusion 93a is provided in the vicinity of the switch 95. In this embodiment, when the sensor main body 93 is viewed from one side in the thickness direction, the positioning protrusion 93a overlaps with the advance / retract position of the switch 95. A fixing hole 93b that penetrates the sensor main body 93 in the thickness direction is formed at a position spaced from the positioning protrusion 93a.

[0044] A lever cover 100 is fastened to the cover fastening portion 79 of the left lever pivot 70. The lever cover 100 is shaped to cover the left lever pivot 70 from above and is open below. The lever cover 100 has a plate-shaped cover upper surface portion 101. The cover upper surface portion 101 overlaps with the lever support portion 73 of the left lever pivot 70 when viewed in the axial direction (see Figure 5). The cover upper surface portion 101 is formed with an insertion hole 101a (see Figure 7) that penetrates through in the thickness direction. The lower surface (inner surface) of the cover upper surface portion 101 is formed with a plurality of protrusions 101c, 101d that protrude downward.

[0045] A cover inner wall portion 102 extending downward is formed at the right end (inner end in the vehicle width direction) of the cover upper surface portion 101. The cover inner wall portion 102 is cut out in a generally U-shape from bottom to top, and a cable guide portion 102a protruding to the right in a semi-cylindrical shape is formed in the cover inner wall portion 102 (see FIG. 4). The clutch cable 132 is guided out from the cable guide portion 102a while entering the cable guide portion 102a.

[0046] A cover front surface portion 103 extending downward is formed at the front end of the cover upper surface portion 101. The cover front surface portion 103 extends downward the same length as the cover inner wall portion 102. A cover outer wall portion 104 extending downward is formed at the left end (outer end in the vehicle width direction) of the cover upper surface portion 101. The cover outer wall portion 104 extends downward a shorter length than the cover front surface portion 103. The lever cover 100 is fastened in a state where the protrusions 101c and 101d make it easy to maintain the space between the cover upper surface portion 101 and the lever support portion 73. The lever cover 100 covers the sensors 91 and 92 from above, the front side, and the right side.

[0047] Next, an example of assembly of the clutch lever support mechanism 63 will be described with reference to FIG. The left lever pivot 70 is fixed to the handle 21. That is, the handle 21 is inserted into the handle fixing portion 71, and a fastening member 111 is inserted from the front into the fastening hole 71b. When the fastening member 111 is fastened, the split groove 71a is tightened, and the left lever pivot 70 is fixed to the handle 21 (see FIGS. 5 and 6).

[0048] The clutch lever 80 has a lever base 82 accommodated in the lever accommodating portion 74 of the left lever pivot 70. A pivot shaft 112 is inserted from above through the pivot shaft holes 73a1, 73b1 of the left lever pivot 70 and the pivot shaft hole 82a of the clutch lever 80. In this embodiment, the pivot shaft 112 is bolt-shaped, and a fixing nut 113 is fastened to the lower end of the pivot shaft 112. This allows the clutch lever 80 to be pivotally supported on the left lever pivot 70. That is, the clutch lever 80 is supported to be pivotable between a connected position P0 (see FIGS. 11 and 12) where the abutment surface 81a of the clutch lever 80 abuts against the lever support portion 73 of the left lever pivot 70, and a disconnected position P1 (see FIGS. 11 and 12) where the first protrusion 85 of the clutch lever 80 abuts against the lever abutment portion 75a. At this time, the first protrusion 85 of the clutch lever 80 protrudes above the lever support portion 73 through the first opening 75. Also, the second protrusion 86 of the clutch lever 80 protrudes below the lever support portion 73 through the second opening 76.

[0049] A cylindrical joint 114 is fixed to the cable guide hole 74a of the left lever pivot 70. As shown in Figures 5 and 6, an outer cable 132a of the clutch cable 132 is fixed to the joint 114. The inner cable inside the outer cable 132a passes through the joint 114 and is engaged with the cable engaging portion 83 of the clutch lever 80 via a retainer.

[0050] The disconnection detection sensor 91 is attached to the sensor attachment portion 77 of the left lever pivot 70. That is, the positioning protrusion 93a of the disconnection detection sensor 91 is inserted into the positioning recess 77a of the sensor attachment portion 77, and the fixing hole 93b is aligned with the sensor fastening portion 77b of the sensor attachment portion 77. A fastening member 115 is inserted into the fixing hole 93b from above and fastened to the sensor fastening portion 77b. In this manner, the disconnection detection sensor 91 is attached to the sensor attachment portion 77 of the left lever pivot 70. At this time, when viewed in the axial direction from above (see FIG. 5), the terminal 94 of the disconnection detection sensor 91 is located on the side farther away from the handle 21 than the spacer portion 73c. Furthermore, the switch 95 of the disconnection detection sensor 91 is located within the first opening 75. The switch 95 of the disconnection detection sensor 91 can be pressed in by the first protrusion 85 of the clutch lever 80.

[0051] The connection detection sensor 92 is attached to the sensor attachment portion 78 of the left lever pivot 70. That is, the positioning protrusion 93a of the disconnection detection sensor 92 is inserted into the positioning recess 78a of the sensor attachment portion 78, and the fixing hole 93b is aligned with the sensor fastening portion 78b of the sensor attachment portion 78. A fastening member 116 is then inserted into the fixing hole 93b from below and fastened to the sensor fastening portion 78b. In this manner, the position detection sensor 92 is attached to the sensor attachment portion 78 of the left lever pivot 70. At this time, when viewed in the axial direction from below (see FIG. 6 ), the terminal 94 of the connection detection sensor 92 is located closer to the handlebar 21 than the spacer portion 73c. Furthermore, the switch 95 of the connection detection sensor 92 is located within the second opening 76. The switch 95 of the connection detection sensor 92 can be pressed in by the second protrusion 86 of the clutch lever 80.

[0052] A cable 133 is connected to the terminals 94 of the disconnection detection sensor 91 via a pair of connecting portions 133a. The cable 133 extends forward from the disconnection detection sensor 91, passes above the joint 114, is bent downward from the front side of the joint 114 in a U-shape, and extends rearward. When bent rearward, the cable 133 extends rearward so as to overlap below the joint 114 and the spacer portion 73c, as viewed in the axial direction from below (see FIG. 6), and passes below the left lever pivot 70 to be introduced into the left handle switch 62.

[0053] A cable 134 is connected via a pair of connecting portions 134a to the terminals 94 of the connection detection sensor 92. The cable 134 extends rearward from the connection detection sensor 92, passes below the left lever pivot 70, and is introduced into the left handlebar switch 62. The cables 133 and 134 introduced into the left handlebar switch 62 are led out from the left handlebar switch 62 as a harness 131 and connected to an ECU (not shown).

[0054] Figure 11 is an explanatory view of the operation as viewed from above in the axial direction, and Figure 12 is an explanatory view of the operation as viewed from below in the axial direction. In the clutch lever support mechanism 63, the clutch lever 80 can pivot about the pivot shaft 112. The clutch lever 80 can pivot between an engaged position P0 indicated by a solid line and a disengaged position P1 indicated by a two-dot chain line. When the clutch lever 80 pivots, the first convex portion 85 of the clutch lever 80 moves on an imaginary circle C1 centered on the pivot shaft 112. The second convex portion 86 of the clutch lever 80 moves on an imaginary circle C2 centered on the pivot shaft 112. Since the imaginary circles C1 and C2 are both imaginary circles centered on the pivot shaft 112, they are concentric circles. Therefore, the first convex portion 85 and the second convex portion 86 are located on concentric circles centered on the pivot shaft 112. Similarly, the first opening 75 and the second opening 76, through which the first convex portion 85 and the second convex portion 86 enter and move, are located on concentric circles centered on the pivot shaft 112.

[0055] In particular, in this embodiment, the first protrusion 85 and the second protrusion 86 are arranged on both sides of the oscillation shaft 112. Similarly, the first opening 75 and the second opening 76 are arranged on both sides of the oscillation shaft 112. In detail, in this embodiment, the first protrusion 85 and the second protrusion 86 are provided on both sides of a line L0 connecting the oscillation shaft 112 and the spacer portion 73c (the center of the oscillation shaft 112 and the front-to-rear center at the right end of the spacer portion 73c). Similarly, the first opening 75 and the second opening 76 are provided on both sides of the line L0. The sensor mounting portions 77, 78 are provided on both sides of the line L0.

[0056] When the clutch lever 80 is in the engaged position P0, the inner cable of the clutch cable 132 is pulled by a biasing member (not shown), and the abutment surface 81a is held in a state in which it abuts against the left lever pivot 70. At this time, the second protrusion 86 presses the switch 95 of the connection detection sensor 92, so the connection detection sensor 92 turns ON, and the fact that the connection detection sensor 92 is ON is input to the ECU. Therefore, the ECU can detect that the clutch lever 80 has moved to the engaged position P0 and the transmission is engaged. Note that at this time, the first protrusion 85 of the clutch lever 80 is separated from the switch 95 of the disengagement detection sensor 91, so the disengagement detection sensor 91 is OFF.

[0057] When the clutch lever 80 is operated to move to the disengaged position P1, it rotates about the swing shaft 112, and the cable engagement portion 83 moves in a direction away from the left lever pivot 70. As a result, the inner cable of the clutch cable 132 is pulled by the clutch lever 80, and the clutch of the transmission is disengaged. At this time, the first protrusion 85 of the clutch lever 80 moves toward the disengagement detection sensor 91 and presses the switch 95 of the disengagement detection sensor 91. As a result, the disengagement detection sensor 91 turns ON, and the fact that the disengagement detection sensor 91 is ON is input to the ECU. Therefore, the ECU can detect that the clutch lever 80 has moved to the disengaged position P1 and the transmission is disengaged. At this time, the second protrusion 86 of the clutch lever 80 is separated from the switch 95 of the position detection sensor 92, and the position detection sensor 92 is OFF.

[0058] In this embodiment, the ECU can accurately detect whether the clutch lever 80 is in the disengaged position P1 or the engaged position P0.

[0059] In this embodiment, the ECU executes idling stop processing based on inputs from sensors 91 and 92. For example, when the gear position of the transmission is in neutral, the ECU stops the power unit 12 serving as the engine. Also, for example, when the gear position of the transmission is in-gear, the ECU stops the power unit 12 upon detecting that the clutch lever 80 has moved to the disengaged position P1. In this way, in this embodiment, an appropriate idling stop function can be provided according to the driving situation.

[0060] As described above, according to this embodiment to which the present invention is applied, in the saddle-ride type vehicle 10 that includes the clutch lever 80, the swing shaft 112 that swingably supports the clutch lever 80, the left lever pivot 70 on which the swing shaft 112 is provided, and the disconnection detection sensor 91 and the connection detection sensor 92 that have a switch 95 that is pressed by the clutch lever 80, the disconnection detection sensor 91 is fixed to the upper surface portion 73a of the left lever pivot 70, the connection detection sensor 92 is fixed to the lower surface portion 73b of the left lever pivot 70, the switch 95 of the disconnection detection sensor 91 and the switch 95 of the connection detection sensor 92 are arranged concentrically on either side of the swing shaft 112 when viewed in the axial direction of the swing shaft 112, and the switch 95 of the disconnection detection sensor 91 is pressed when the clutch lever 80 moves to the disengaged position P1, and the switch 95 of the connection detection sensor 92 is pressed when the clutch lever 80 moves to the engaged position P0.

[0061] According to this configuration, the switch 95 of the disconnection detection sensor 91 and the switch 95 of the connection detection sensor 92 can be arranged concentrically on either side of the swing shaft 112 when viewed in the axial direction of the swing shaft 112, and a saddle-ride type vehicle 10 can be provided that can accurately detect when the clutch lever 80 has moved to the disengaged position P1 or the engaged position P0 with a simple configuration that prevents the layout of components such as the sensors 91 and 92 from becoming complicated. Therefore, even in saddle-ride type vehicles 10 of models such as LMCs (Light Motor Cycles), which require a small engine displacement and low price, it is possible to easily install an idle stop function appropriate for the driving situation.

[0062] In this embodiment, a first convex portion 85 is provided on the upper surface (one surface in the swing axis direction) of the clutch lever 80, which presses the switch 95 of the disconnection detection sensor 91 when the clutch lever 80 is moved to the disconnection position P1, and a second convex portion 86 is provided on the lower surface (the other surface in the swing axis direction) of the clutch lever 80, which presses the switch 95 of the connection detection sensor 92 when the clutch lever 80 is moved to the connection position P0, and the first convex portion 85 and the second convex portion 86 are arranged concentrically on either side of the swing axis 112 when viewed in the axial direction of the swing axis 112. According to this configuration, by adding a simple structure to the clutch lever 80, the switch 95 of the disconnection detection sensor 91 and the switch 95 of the connection detection sensor 92 can be pressed with high accuracy. Therefore, even in models such as LMCs, which require a small displacement and low price, it is easy to install an idle stop function appropriate for the driving situation.

[0063] In addition, in this embodiment, a first opening 75 is provided on the upper surface 73a of the left lever pivot 70, through which the first protrusion 85 of the clutch lever 80 can enter, and a second opening 76 is provided on the lower surface 73b of the left lever pivot 70, through which the second protrusion 86 of the clutch lever 80 can enter, and the first opening 75 and the second opening 76 are arranged concentrically on either side of the oscillating shaft 112 when viewed in the axial direction of the oscillating shaft 112. According to this configuration, the first protrusion 85 can enter the first opening 75 and the second protrusion 86 can enter the second opening 76, which makes it difficult for the switch 95 of the disconnection detection sensor 91 and the switch 95 of the connection detection sensor 92 to protrude from the left lever pivot 70 when viewed in the axial direction of the swing shaft 112.

[0064] In this embodiment, a lever cover 100 is fastened to the left lever pivot 70, and the lever cover 100 overlaps the disconnection detection sensor 91 and the connection detection sensor 92 in a plan view of the vehicle body. According to this configuration, the location of the switch 95 of the sensors 91, 92 can be easily protected from foreign matter, and the sensors 91, 92 can be easily protected from being wetted by rainwater or the like.

[0065] In this embodiment, the disconnection detection sensor 91 and the connection detection sensor 92 have the same shape. With this configuration, the disconnection detection sensor 91 and the connection detection sensor 92 can be realized by sensors of the same shape, so the layout of the sensors 91, 92 and the connecting parts of the sensors 91, 92 can be shared. Also, because the disconnection detection sensor 91 and the connection detection sensor 92 can be realized by a common sensor, it is easy to reduce the number of types of parts. Therefore, with this configuration, it is possible to prevent an increase in costs.

[0066] [Other embodiments] The above-described embodiment merely shows one aspect of the present invention, and any modifications and applications are possible without departing from the spirit of the present invention.

[0067] In the above embodiment, a motorcycle equipped with a power unit 12 having an internal combustion engine has been described as an example of the saddle-ride type vehicle 10, but the power unit may be an electric motor. In other words, the saddle-ride type vehicle may also be an electric vehicle.

[0068] In the above embodiment, a motorcycle having a front wheel 13 and a rear wheel 15 has been used as an example of the saddle-ride vehicle 10, but the present invention is not limited to this, and can be applied to a three-wheel saddle-ride vehicle having two front or two rear wheels, or a saddle-ride vehicle having four or more wheels.

With this configuration, the first sensor switch and the second sensor switch can be arranged concentrically on either side of the oscillating shaft when viewed in the axial direction of the oscillating shaft, and a saddle-ride type vehicle can be provided that can accurately detect when the clutch lever has moved between the gripped position and the ungripped position with a simple configuration that prevents the layout of components such as sensors from becoming complicated.
