And the like. Although the lead acid battery is illustrated as the battery 20, it is not specifically limited to this, A various storage battery is employable.

  The vehicle body of the motorcycle 10 is configured with a frame 21 as a base, and the frame 21 is covered with a cover (not shown). Above the cover, a seat (not shown) for the driver to get on is provided slightly behind the power unit 18. In other words, the power unit 18 is provided approximately in the middle between the front wheel 14 and the rear wheel 16 and slightly below the front of the seat.

  The control unit 19 and the battery 20 are disposed slightly forward from the lower side of the seat and are disposed inside the cover. In the vicinity of the power unit 18 on the right side of the motorcycle 10, a step 22 for the driver to place his / her foot is provided.

  Here, the power unit 18 includes an internal combustion engine 26 that generates a traveling driving force. That is, the motorcycle 10 is a hybrid type that uses both the power unit 18 and the internal combustion engine 26 as power sources, and brakes the front wheels 14 and the rear wheels 16 via the levers 15 and 17 by the driver's manual operation. The so-called manual brake type.

  The internal combustion engine 26 is connected to an exhaust pipe 27 (see FIG. 1) for discharging exhaust gas after combustion occurs in the combustion chamber 26a (see FIG. 2) of the internal combustion engine 26. A muffler 28 is connected to the exhaust pipe 27.

  Further, a stop lamp 34 is disposed below the tandem seat 29.

  The speed change method of the motorcycle 10 is a so-called four-speed rotary type, and the shift position value becomes neutral → 1 → 2 → 3 → 4 every time the rear of a shift pedal (not shown) provided on the left side of the motorcycle 10 is depressed. On the contrary, every time the front of the shift pedal is depressed, 4 → 3 → 2 → 1 → neutral is shifted down. In the four-speed rotary type, the clutch operation at the time of shifting is performed in sequence and automatically by the operation of the shift pedal, and therefore a clutch lever or the like is not necessary.

  The configuration of the power unit 18 will be described with reference to FIG. 2 is a cross-sectional plan view of the power unit 18, where the left-right direction corresponds to the vehicle width direction, the upper direction corresponds to the front of the vehicle, and the lower direction corresponds to the rear of the vehicle.

  As shown in FIG. 2, the power unit 18 includes an internal combustion engine 26 and a motor / generator 36 that generate travel driving force, a starting clutch 40 provided on a crankshaft 38 of the internal combustion engine 26, and the starting clutch 40. The transmission includes a step-shifted transmission 42 for rotating the crankshaft 38 and a shift clutch 44 provided between the start clutch 40 and the transmission 42. The motor / generator 36 functions as a starter motor that rotationally drives the crankshaft 38 when the internal combustion engine is started. In the power unit 18, the cylinder head 46a, the cylinder 46b, and the crankcase 46c are integrally coupled to form an extended portion. The crankshaft 38 is rotatably supported by a plurality of bearings 48a, 48b, 48c.

  The internal combustion engine 26 supplies sparks to a connecting rod 50 connected to a crankshaft 38, a piston 52 that is provided at the tip of the connecting rod 50 and reciprocates in the cylinder 46b, and a combustion chamber 26a at the inner end of the cylinder 46b. An ignition plug 54 and a cam mechanism 56 that opens and closes a valve (not shown) to intake and exhaust the combustion chamber 26a. The cam mechanism 56 is driven from the crankshaft 38 via a timing chain 56a.

  The motor / generator 36 is disposed at the left end portion of the crankshaft 38, is provided on the crankcase 46 c and is configured coaxially with the crankshaft 38, and is fixed to the end portion of the crankshaft 38 to be fixed to the stator 58. And an outer rotor 60 provided so as to cover. The stator 58 is provided with a plurality of coils 61 arranged in an annular shape. A plurality of magnets 62 arranged so as to form a narrow gap with respect to the coil 61 are fixed to the outer rotor 60. The motor / generator 36 is controlled to rotate under the action of the control unit 19.

  The starting clutch 40 connects and disconnects (hereinafter also referred to as disconnection) between the crankshaft 38 and the primary gear 67 when starting and stopping, and is disposed at the right end of the crankshaft 38. The starting clutch 40 includes a cup-shaped outer case 66 fixed to one end of a sleeve 64, a primary gear 67 provided at the other end, an outer plate 68 fixed to the right end of the crankshaft 38, and an outer plate. 68, a shoe 72 attached to the outer line portion 68 through the weight 70 so as to face radially outward, and a spring 74 for urging the shoe 72 radially inward. In the starting clutch 40, the outer case 66 and the shoe 72 are separated when the internal combustion engine speed N is equal to or less than a predetermined value, and the crankshaft 38 and the transmission clutch 44 are disconnected (a disconnected state in which no power is transmitted). ). When the internal combustion engine speed N increases and exceeds a predetermined value, the centrifugal force acting on the weight 70 resists the elastic force acting radially inward by the spring 74, and the weight 70 moves radially outward, thereby causing the shoe 72 to move. Presses the inner peripheral surface of the outer case 66 with a force equal to or greater than a predetermined value. As a result, the rotation of the crankshaft 38 is transmitted to the primary gear 67 through the outer case 66, and a connection state is established in which power is transmitted.

  The transmission clutch 44 connects and disconnects the primary gear 67 and the main shaft 76, and is disposed at the right end portion of the main shaft 76. The speed change clutch 44 includes a cup-shaped outer housing 78 that meshes with the primary gear 67, a boss 80 provided on the inner side of the outer housing 78, and an outer housing 78 and a boss 80 that are alternately stacked. A plurality of friction disks 82 and clutch disks 84, a pressure plate 86, a clutch spring 88 that elastically urges the pressure plate 86 to be in close contact with the boss 80, and a boss via a deep groove ball bearing 90. And a clutch operating mechanism 92 for pressing 80 in the axial direction. The clutch operation mechanism 92 operates in conjunction with the operation of the shift pedal.

  One of the plurality of friction disks 82 and clutch disks 84 provided in a stacked manner faces the pressure plate 86, and the other faces the support surface 80 a that is a part of the boss 80. When the clutch operating mechanism 92 is not operated by the shift pedal, the friction disk 82 and the clutch disk 84 are strongly held between the pressure plate 86 and the support surface 80a, and the torque input from the primary gear 67 is transmitted to the boss 80. Further, the boss 80 is transmitted to the main shaft 76 by the spline configuration, and is connected.

  When the boss 80 is pressed by the clutch operating mechanism 92, the boss 80 moves in the axial direction while compressing the clutch spring 88, and is separated from the friction disc 82 and the clutch disc 84. Therefore, the torque of the primary gear 67 is not transmitted to the main shaft 76, and is cut off.

  The speed change clutch 44 detects the output rotation speed No based on the input rotation sensor 94 for detecting the input rotation speed Ni based on the number of teeth of the outer housing 78 and the outer peripheral teeth at a predetermined position of the main shaft 76. An output rotation sensor 96 is provided. The input rotation sensor 94 and the output rotation sensor 96 are non-contact type, and supply the detected speed signal to the control unit 19.

  The transmission 42 transmits the rotation supplied from the shift clutch 44 to the rear wheel 16 by performing a step-shift based on the operation of the shift pedal. The transmission 42 includes the main shaft 76 as an input shaft, a counter shaft 100 arranged in parallel to the main shaft 76, and drive gears 102a, 102b, 102c and 102d provided on the counter shaft 100. The driven gears 104a, 104b, 104c and 104d provided on the main shaft 76, the shift fork 106a engaged with the drive gear 102a, the shift fork 106b engaged with the driven gear 104c, and the shift forks 106a and 106b are pivoted. And a shift drum 112 for sliding the end portions of the shift forks 106a and 106b along the grooves 110a and 110b. The drive gears 102a, 102b, 102c and 102d mesh with the driven gears 104a, 104b, 104c and 104d in this order. When the drive gear 102b slides left and right, the side dowels engage with the adjacent drive gear 102a or 102c, and when the driven gear 104c slides left and right, the side dowels engage with the adjacent driven gear 104b or 104d. To do.

  The drive gears 102 a and 102 c are held rotatably with respect to the main shaft 76, and the driven gears 104 b and 104 d are held rotatably with respect to the counter shaft 100. The drive gear 102b and the driven gear 104c are splined to the main shaft 76 and the counter shaft 100 and are slidable in the axial direction. The drive gear 102d and the driven gear 104a are fixed to the main shaft 76 and the counter shaft 100.

  A rotation mechanism 122 is provided at the end of the shift drum 112, and the operation of the shift pedal rotates the shift drum 112 via the shift spindle by the rotation mechanism 122. As a result, the shift forks 106a and 106b move in the axial direction along the grooves 110a and 110b, and the drive gear 102b and the driven gear 104c are slid according to the shift speed.

  When the drive gear 102b slides leftward, the torque of the main shaft 76 is transmitted to the counter shaft 100 via the drive gears 102b and 102a and the driven gear 104a. When the drive gear 102b is in the neutral position and the driven gear 104c slides to the left, the torque of the main shaft 76 is transmitted to the counter shaft 100 via the drive gear 102b, the driven gear 104b, and the driven gear 104c. When the driven gear 104c is in the neutral position and the drive gear 102b slides to the right, the torque of the main shaft 76 is transmitted to the counter shaft 100 via the drive gears 102b and 102c and the driven gear 104c. When the drive gear 102b is in the neutral position and the driven gear 104c moves to the right, the torque of the main shaft 76 is transmitted to the counter shaft 100 via the drive gear 102d, the driven gear 104d, and the driven gear 104c. In this way, the rotation of the main shaft 76 is shifted in four stages and transmitted to the counter shaft 100 or is in a neutral state.

  The main shaft 76 and the counter shaft 100 are rotatably held by bearings 114a, 114b, 116a, and 116b. A sprocket 118 is provided at the end of the counter shaft 100, and the sprocket 118 transmits rotation to the rear wheel 16 via the chain (not shown). A vehicle speed sensor 120 that detects the rotational speed of the counter shaft 100 in a non-contact manner is provided near the counter shaft 100, and supplies the detected rotational speed to the control unit 19. The rotational speed of the counter shaft 100 detected by the vehicle speed sensor 120 indicates the vehicle speed V.

  Here, as shown in FIG. 3, a tube hose 130 is connected to the rear wheel brake lever 17, and the rear wheel 16 is braked by hydraulic control via the tube hose 130.

  A lever pivot 134 is disposed on the side of the bracket 132 attached to the handle 13, and the rear wheel brake lever 17 is pivotally supported by the lever pivot 134. A pressing screw 137 is formed below the rear wheel brake lever 17 at the end of the lever pivot 134 side. The pressing screw 137 has a tongue piece 136 that is bent and extends vertically downward. One end of a pressing rod 140 (pressing member) that is surrounded and protected by the rod guide 138 contacts the tongue piece 136. A tunnel portion 141 is provided on the lower surface of the bracket 132, and the rod guide 138 is passed through the tunnel portion 141.

  On the other hand, a regenerative rotation sensor 144 (brake displacement amount detecting means) as a potentiometer is fixed to the lower surface of the bracket 132 via a sensor mounting bracket 142. As shown in FIG. 4, the regenerative rotation sensor 144 has a sensor main body 146 and a cam 150 (detected body) rotatably supported by a support shaft 148, and is connected to the sensor main body 146. The lead wires 152a to 152c send the rotational displacement amount of the cam 150 to the control unit 19 as signal information.

  The cam 150 is provided with a spiral protrusion 154, and the other end of the pressing rod 140 is in contact with the spiral protrusion 154.

  A coil spring (not shown) is wound around the cam 150 inside the sensor body 146. In other words, the cam 150 is elastically biased toward the pressing rod 140 by the coil spring.

  As shown in FIG. 3, the regenerative rotation sensor 144 is attached to the bracket 132 with the cam 150 facing upward, in other words, the cam 150 faces the bracket 132. For this reason, the cam 150 cannot be visually recognized from the outside.

  The motorcycle 10 according to the present embodiment is basically configured as described above. Next, the function and effect will be described.

  When the operation of the motorcycle 10 is started, one of the levers 15 and 17 is gripped by the driver. The case where the rear wheel brake lever 17 is gripped will be described as an example. As the gripped rear wheel brake lever 17 rotates in the direction of the arrow X in FIG. The part 136 begins to separate the pressing rod 140. As a result, the pressing rod 140 starts to move backward, and the pressing force of the pressing rod 140 on the cam 150 of the cam 150 is reduced.

  For this reason, it rotates in the direction of arrow A under the elastic action of the coil spring so that the position of the spiral convex portion 154 is displaced. That is, the cam 150 is rotationally displaced in the arrow A direction. The amount of rotation at this time is recognized by the control unit 19 as the amount of displacement of the rear wheel brake lever 17.

  The control unit 19 prevents the stop lamp 34 from being lit when the rotation amount is less than a predetermined first threshold value, while giving a control signal of “stop lamp lighting” when the rotation amount exceeds the first threshold value. When the rotation amount further increases and becomes equal to or greater than a predetermined second threshold value, a control signal for “startable start of internal combustion engine” is issued. When the control unit 19 receives this control signal, it is possible to start the internal combustion engine by pressing the cell switch.

  FIG. 5 is a graph showing the relationship between the amount of rotation of the brake lever 17 for the rear wheel, the amount of displacement of the brake lever, the lighting timing of the stop lamp 34, and the timing at which the internal combustion engine can be started. In FIG. 5, point M represents the stop lamp lighting start time, and point N represents the time when the internal combustion engine is ready to start. The vertical axis represents the output voltage of the sensor. As described above, in the present embodiment, the lighting timing of the stop lamp 34 and the timing at which the internal combustion engine can be started are determined based on the detection result of the regenerative rotation sensor 144.

  When the driver presses the cell switch in this state, the internal combustion engine 26 is started. Thereafter, when the driver releases his left hand from the rear wheel brake lever 17, the rear wheel brake lever 17 rotates in the direction of arrow Y in FIG. 4 to return to the original position. On the other hand, the cam 150 pressed by the tongue piece 136 rotates in the direction of arrow A against the elastic action of the coil spring and returns to the original position. Move forward and return to the original position.

  When the internal combustion engine speed N increases as the accelerator is operated, the starting clutch 40 shifts to the connected state based on the centrifugal action. As a result, the torque of the crankshaft 38 is transmitted to the rear wheel 16 via the start clutch, the shift clutch 44, the main shaft 76, and the transmission 42, and the motorcycle 10 starts.

  While the motorcycle 10 is traveling, the control unit 19 performs control processing of the power unit 18. In other words, the internal combustion engine speed N, the input speed Ni, the output speed No, the vehicle speed V, and the spindle rotation θ are input, and control is performed so that the gear is shifted up or down depending on the driving situation.

  The motor / generator 36 receives power from the battery 20 and rotates the crankshaft 38 together with the internal combustion engine 26 under the rotational control action of the control unit 19 according to the traveling state, or regenerates based on the rotational power of the crankshaft 38. Power generation is performed, and the generated power is charged in the battery 20.

  Thus, while the motorcycle 10 travels, fuel and air are supplied to the combustion chamber 26a (see FIG. 2) of the internal combustion engine 26, and these are burned by the sparks emitted from the spark plug 54. The high-temperature exhaust gas after combustion is discharged from the muffler 28 to the atmosphere via the exhaust pipe 27 from the combustion chamber 26a.

  When reducing the speed of the motorcycle 10 or stopping the motorcycle 10, the driver usually holds both the front wheel brake lever 15 and the rear wheel brake lever 17 to hold these levers 15, 17 is rotated. If the rear wheel brake lever 17 side is described as an example, the tongue piece 136 is moved away from the pressing rod 140 as the rear wheel brake lever 17 rotates in the direction of the arrow X in FIG. As a result, the pressing rod 140 moves backward and the pressing force of the cam 150 on the spiral convex portion 154 is reduced. The rotation amount of the cam 150 of the regenerative rotation sensor 144 at this time is recognized by the control unit 19 as the displacement amount of the rear wheel brake lever 17.

  As described above, when the rotation amount of the cam 150 is less than the first threshold value, the control unit 19 prevents the stop lamp 34 from being energized so that the stop lamp 34 is not lit. That is, even if the rear-wheel brake lever 17 is displaced, if the amount of rotation of the cam 150 based on the amount of displacement is less than the first threshold value, no current is supplied to the stop lamp 34. Therefore, the stop lamp 34 does not light up. In other words, the stop lamp 34 does not light up to the extent that the driver has slightly rotated the rear wheel brake lever 17.

  When the rear wheel brake lever 17 is further rotated, and the amount of rotation of the cam 150 becomes equal to or greater than the first threshold value, the control unit 19 issues a control signal of “stop lamp lighting”. As a result, the stop lamp 34 is energized, and the stop lamp 34 is turned on. While the cam 150 rotates in this way, a regenerative current is generated in the control unit 19 according to the amount of rotation.

  Then, at the same time as the rotation amount becomes equal to or greater than the first threshold value, hydraulic control is performed via the tube hose 130, and the rear wheel brake starts to operate effectively. That is, the rotation of the rear wheel 16 is reduced or stopped.

  Thus, according to the present embodiment, the displacement amount (operation amount) of the rear wheel brake lever 17 is detected from the rotational displacement amount of the cam 150 that is the detection target, and the stop is based on the detection result. The lighting timing of the lamp 34 and the startable timing of the internal combustion engine are determined. Accordingly, there is no need to provide a stop lamp switch and a start switch, and the number of parts can be reduced. Therefore, the motorcycle 10 can be manufactured by a simple assembling operation, and the configuration is also simplified. In addition, since the number of parts is reduced, the cost can be reduced.

  In the above-described embodiment, the motorcycle 10 in which the clutch operation and the shift operation are combined with the operation of the shift pedal has been described as an example. However, the present invention is not limited to this and is provided near the handle. It may be a motorcycle that performs clutch operation using a shift lever.

  Further, although the motorcycle 10 according to the present embodiment is a hybrid type, the present invention is not particularly limited to this, and may be an electric motorcycle using only a motor as a travel drive source, or an internal combustion engine. A motorcycle using only the engine as a driving source may be used.

  Furthermore, in the present embodiment, the rear wheel brake lever 17 side that the driver grips with the left hand has been described as an example, but the front wheel brake lever 15 side that the driver grips with the right hand may be configured similarly. Needless to say.

  Furthermore, the vehicle according to the present invention is not particularly limited to a motorcycle, and may be a four-wheeled vehicle. Of course, also in this case, the traveling drive source can be selected as appropriate, such as a hybrid type, only a motor, and only an internal combustion engine.
