An occupant (driver) J seated on the front portion of the seat 20 takes a driving posture in which the left and right grip portions of the handle 9 are gripped with both hands and both feet are placed on the left and right upper surfaces of the floor cover 19. At this time, the front cover 16 is located in front of the occupant J (front), and the front cover 16 protects the occupant J from the traveling wind pressure.

  Referring also to FIG. 2, a pair of left and right headlamps 21 extending at an angle so as to be inclined rearward and upward along the outer surface of the front cover 16 are arranged on both sides of the front portion of the front cover 16 so as to be spaced apart from each other. Established. A pair of left and right side mirrors 22 are attached to the left and right sides of the front cover 16 so as to protrude outward in the left and right directions so as to project forward of the left and right grip portions of the handle 9. Each side mirror 22 has a casing that becomes thinner toward the front side, and left and right front blinkers 23 are arranged at the front of the casing. In FIG. 2, the line CL indicates the left-right center line of the motorcycle 1.

  Here, referring also to FIG. 3, the upper and left and right inner portions of the front cover 16 are configured as a screen 25 made of, for example, a transparent or translucent transparent resin such as polycarbonate. The screen 25 includes a plate-like screen body 26 that forms a front wall portion (outer wall portion) that rises rearward in the upper portion of the front cover 16, and a plate-like screen body 26 that extends substantially in the left-right direction. The air duct 27 is provided.

  The air duct 27 has a predetermined thickness in the inside / outside direction of the front cover 16 (inside / outside direction of the cover), and is provided so as to enter the back side (inside the cover) of the screen body 26. The screen 25 is symmetrical and is disposed between both sides of the front cover 16 so that the occupant J can visually recognize the front of the vehicle through the screen 25. The portion of the front cover 16 excluding the screen 25 (cover main body 16a) is made of a colored impermeable resin such as ABS.

  An air inlet 28 to the air duct 27 opens toward the front of the vehicle at the lower end (front end) of the screen 25, and an air outlet 29 from the air duct 27 opens upward at the upper end of the screen 25. . The air introduction port 28 is located between the left and right headlamps 21 at the front end portion of the front cover 16 (right and left central portion), and the air blowing port 29 is located across the left and right ends of the upper edge portion of the front cover 16. The height of the upper edge portion of the screen 25 (front cover 16) is set so as not to obstruct the front view of the occupant J (about the chest height).

  The air inlet 28 opens along the front end surface of the front cover 16 that rises rearward, has an inverted trapezoidal shape with a narrow lower side when viewed from the front (front view), and has an upper side portion 28a that is convex downward. Is done. With the upper side portion 28a of the air introduction port 28 as a lower edge portion (front edge portion), the screen body 26 is provided so as to rise obliquely upward and rearward. The screen main body 26 is curved so as to be recessed obliquely downward and rearward in a side view (to be convex toward the inside of the cover), and air (running wind) from the front of the vehicle along the outer surface (front surface) 26a. ) Diagonally upward and backward. In addition, the both sides of the front cover 16 that supports both sides of the screen 25 form curved surfaces 16b (see FIG. 2) that wrap around to the rear in the left and right sides, and receive the traveling wind from the front of the vehicle to the rear and left and right sides.

  The air outlet 29 has a horizontally long rectangular shape that is long to the left and right with respect to the air inlet 28 and has a reduced thickness in the inside and outside of the cover (herein, the front-rear direction), and is slightly forward at the upper edge of the front cover 16. Open along the lower end face. The front side 29 a of the air outlet 29 is formed by the upper edge of the screen body 26. In addition, it can be said that the air outlet 29 is provided with a predetermined left-right width in the left-right center portion of the upper edge portion of the front cover 16.

  The air duct 27 includes a pair of left and right side walls 31 erected rearward from both side edges of the screen body 26, a rear wall 32 extending between the rear edges of the both side walls 31, and front and rear of both side walls 31. And a partition wall 33 extending between the intermediate portions. The rear wall portion 32 is curved in a convex shape toward the diagonally lower back in a side view along the screen main body 26, and is formed along the screen main body 26 by the rear wall portion 32, both side wall portions 31 and the screen main body 26. An air flow path 30 of an air duct 27 extending smoothly and continuously from the air inlet 28 to the air outlet 29 is formed.

  The air flow path 30 is divided into two outer and inner flow paths 30 a ′ and 30 b ′ by a partition wall 33 that is curved in a side view along the screen body 26 and the rear wall 32. The partition wall 33 is provided from the air inlet 28 to the air outlet 29, and imparts a rectifying effect to the traveling wind flowing in the air duct 27 and contributes to improvement of the rigidity of the entire screen 25.

  The left and right width of the upper side portion 28a of the air introduction port 28 and the left and right width of the front side portion 29a of the air blowing port 29 are substantially the same, and the left and right width of the screen body 26 is substantially the same across the top and bottom. The left and right width of the screen body 26 is provided substantially the same as the full left and right width of the air duct 27.

  On the other hand, the left and right widths of the partition wall portion 33 and the rear wall portion 32 in the air inlet port 28 are narrower than those in the air outlet port 29, respectively. The air introduction port 28 is formed so that the left and right widths are narrowed in the order of the screen main body 26, the partition wall portion 33, and the rear wall portion 32, and the air outlet 29 is formed of the screen main body 26, the partition wall portion 33, and the rear wall portion 32. This is because the left and right widths are formed in this order. The left and right width of the air duct 27 is maximized at the rear wall portion 32 in the vicinity of the air outlet 29.

  In the outer and inner passages 30a ′ and 30b ′ of the air duct 27, the left and right widths (average left and right widths) of the intermediate portions in the cover inner and outer directions are widened from the air inlet port 28 side toward the air outlet port 29 side. It is formed with smooth and gradual change. Further, the outer and inner flow paths 30a ′ and 30b ′ are formed by gradually and gradually changing so that the thicknesses in the cover inner and outer directions become narrower from the air inlet port 28 side toward the air outlet port 29 side. The

  The cross-sectional areas of the outer and inner flow paths 30 a ′ and 30 b ′ in the cross section orthogonal to the air flow direction are substantially the same from the air inlet 28 to the air outlet 29. Further, in order to make the cross-sectional areas of the outer and inner flow paths 30a ′ and 30b ′ substantially the same, the thickness of the outer flow path 30a ′ that is relatively wide on the air inlet 28 side in the cover inner and outer directions is the inner flow path. It is slightly narrower than that of 30b ′, and on the air outlet 29 side, the thickness of the relatively narrow outer flow path 30a ′ in the cover inside / outside direction is made slightly wider than that of the inner flow path 30b ′.

  As shown in FIG. 3, the lower part (front part) of the air flow path 30 is a curved part 30 a that is curved in a side view so that the rear side is steeper, and the upper part of the air flow path 30 is obliquely upward and rearward. It is set as the linear part 30b extended linearly toward side by side view.

  Referring also to FIG. 1, when the motorcycle 1 having the front cover 16 is traveling, a part of the traveling wind (see arrow A in the figure) that flows substantially horizontally from the front to the rear is the air inlet. 28 is taken into the air duct 27. The traveling wind that has entered the air duct 27 is blown out with directivity from the air outlet 29 obliquely upward and rearward while changing the direction of the flow rearwardly upward along the air flow path 30 (FIG. Middle arrow B).

  At this time, a negative pressure portion (low pressure portion, high flow velocity portion) F (see FIG. 3) is generated by bending the air flow in the curved portion 30a of the air flow path 30. This negative pressure portion F is the screen body. 26 and only a small amount are generated on the back side of the partition wall 33. That is, the partition wall 33 provides a rectifying effect to the traveling wind flowing in the air duct 27 (particularly in the curved portion 30a) and reduces the negative pressure portion F in the air flow path 30 to reduce the pipe resistance. In addition, it contributes to the improvement of the rigidity of the entire screen 25.

  The air flow blown out from the air blowout port 29 acts to change the flow of the traveling wind that passes over the screen 25 and reaches the occupant J diagonally upward and backward (see arrow C in FIG. 1). As a result, it is possible to suppress the amount of traveling airflow toward the occupant J while suppressing the screen height (that is, a good screen effect can be obtained). At this time, the airflow that has changed obliquely upward and rearward is mainly guided around the head of the occupant J (around the helmet). Since the air blowing port 29 is provided so as to extend to the left and right ends of the upper edge portion of the front cover 16, the blowing width of the traveling wind through the air duct 27 is widened, and the range for obtaining the screen effect is increased.

Here, as shown in FIG. 4, the motorcycle 1 includes a cool air device 40 that can cool the traveling wind through the air duct 27 and use this as cool air to supply to the passenger J side.
The cool air device 40 injects mist-like water into the air flow path 30 (inner flow path 30b ′) in the air duct 27 and cools the air blown out from the air duct 27 by the heat of vaporization of the water. In addition to the front cover 16) and the air duct 27, a water storage tank 41 that stores water for supply to the air flow path 30, and an injector 42 that injects water in the water storage tank 41 into the air flow path 30 in a mist form A water supply path 43 that connects the injector 42 and the water storage tank 41, a water pump 44 that is provided in the water supply path 43 and that pumps water to the injector 42 side, and controls the operation of the water pump 44 and the injector 42. A control unit 50, an air flow meter 51 for detecting the amount of traveling air flowing through the air flow path 30, and a water temperature for detecting the water temperature in the water storage tank 41 A sensor 52, an outside air temperature sensor 53 that detects the outside air temperature, a vehicle speed sensor 54 that detects the traveling speed of the motorcycle 1, and a water supply adjustment switch 55 that allows the occupant J to adjust the amount of water supplied to the air flow path 30. It has.

The injector 42 is an electromagnetic type that opens and closes the injection port 42a by reciprocating the plunger in the cylinder depending on whether or not the solenoid coil is energized. The water in the water storage tank 41 is supplied to the injector 42 via the water pump 44. Under pressure, the spray port 42a is opened in this state, thereby spraying mist-like water into the air flow path 30. The injection port 42a of the injector 42 is disposed so as to face upward along the straight line portion 30b on the rear wall portion 32 (outer peripheral side) of the curved portion 30a of the air flow path 30.
The control unit 50 operates the water pump 44 and the injector 42, that is, the air flow path 30 based on the detection information from the air flow meter 51, the vehicle speed sensor 54, the water temperature sensor 52 and the outside air temperature sensor 53 and the position of the water supply adjustment switch 55. Control the supply of water to the water.

  Specifically, the control unit 50 assumes that when the motorcycle 1 is at a low speed (for example, when the vehicle speed is less than 40 km / h), it cannot expect good vaporization of the supplied water due to insufficient running wind. Water supply to the air flow path 30 is stopped, and water supply to the air flow path 30 is performed only at the middle speed of the motorcycle 1 (for example, 40 km / h or more).

In addition to the vehicle speed information, the control unit 50 stops water supply to the air flow path 30 regardless of the vehicle speed information or the like for the same reason as described above when the air volume in the air flow path 30 is less than a predetermined value. To do.
Further, the control unit 50 assumes that the water supplied in the same manner as above cannot be vaporized well when the water temperature in the water storage tank 41 is lower than a predetermined value, or when the outside air temperature is lower than a predetermined value. Regardless of information or the like, water supply to the air flow path 30 is stopped.
That is, the control unit 50 controls the operation of the injector 42 in accordance with the vehicle speed, the air volume, the water temperature, and the outside air temperature, and appropriately increases or decreases the amount of water injected into the air flow path 30.

Thus, by supplying water to the air flow path 30 according to various surrounding conditions, the water can be surely vaporized, and thus the traveling wind can be cooled well through the air flow path 30.
By the way, in the said cold wind apparatus 40, execution / stop of the water supply to the air flow path 30 can be switched by ON / OFF etc. of the water supply adjustment switch 55 provided in the handle | steering-wheel 9, for example. That is, when the water supply adjustment switch 55 is ON, water is automatically supplied to the air flow path 30 by the above-described control, and when the water supply adjustment switch 55 is OFF, the air flow adjustment to the air flow path 30 regardless of the control described above. Stop water supply. In addition, the water supply adjustment switch 55 may have an intermediate position for switching not only the execution and stop of water supply but also the amount of water supply.

  As described above, the cold air device 40 of the motorcycle 1 in the first embodiment is provided at the front of the vehicle body of the motorcycle 1 to obtain a windproof effect on the passenger J behind it, and the front cover 16. The air duct 27 is provided on the cover 16 and guides the traveling wind toward the occupant J, and includes an injector 42 that supplies mist-like water to the air flow path 30 in the air duct 27. .

  According to this configuration, the traveling wind flowing through the air passage 30 is cooled by the heat of vaporization of the mist-like water supplied to the air passage 30 in the air duct 27, and the traveling wind (cold air) is appropriately sent to the passenger J side. By supplying the wind power to the occupant J by the front cover 16, it is possible to provide a comfortable drive by supplying cold air to the occupant J even when the outside air temperature is high.

  The cold air device 40 includes a water pump 44 that supplies the water in the water storage tank 41 to the injector 42 and a control unit 50 that controls the operation of the water pump 44, thereby providing water to the injector 42. As a result, the supply of water to the air flow path 30 can be freely controlled.

  Further, the cold air device 40 includes an air flow meter 51 for detecting the amount of traveling air flowing through the air flow path 30, and the control unit 50 responds to the detection information from the air flow meter 51 and the air flow path 30. By controlling the supply of water to water, water can be appropriately supplied according to the amount of traveling air flowing through the air flow path 30, and the traveling air can be reliably cooled.

  Furthermore, in the said cold wind apparatus 40, the water supply adjustment switch 55 which enables adjustment of the water supply to the said air flow path 30 by the said passenger | crew J is equipped with the air flow path 30 according to a passenger | crew's J preference. It is possible to adjust the temperature of the traveling wind flowing through the air flow path 30 by adjusting whether or not the water is supplied.

  Further, in the cold air device 40, the air flow path 30 has a curved portion 30a, and the injector 42 is disposed in the curved portion 30a, so that the injector 42 is directed toward the downstream side of the air flow path 30. It becomes possible to arrange it straight, and it is possible to promote the vaporization of water and cool the traveling wind well.

  Further, in the cold air device 40, the air duct 27 is provided at the front part of the front cover 16 and opens toward the front of the vehicle, and is provided at the upper part of the front cover 16 and is upward. And the air inlet port 28 and the air outlet port 29 communicate with each other via the air flow path 30 so that the traveling wind taken from the air inlet port 28 is blown out into the air. The air can be blown upward from the mouth 29, and an appropriate screen effect for the occupant J can be obtained while suppressing the height (screen height) of the front cover 16.

  Furthermore, in the cold air device 40, it is not possible to vaporize water from the injector 42 by supplying water to the air flow path 30 only when the detection value of the vehicle speed sensor 54 is within a predetermined range. The supply of water to the air flow path 30 at a low speed (when the traveling air volume is small) or the like can be stopped.

Next, a second embodiment of the present invention will be described with reference to FIG.
The cold air device 140 in this embodiment is mainly different from the first embodiment in that it includes a water supply nozzle 142 that supplies normal pressure water to the air flow path 30 instead of the injector 42. The same parts as those in the first embodiment are designated by the same reference numerals and their description is omitted.

  In addition to the screen 25 (front cover 16) and the air duct 27, the cool air device 140 includes the storage tank, the air flow meter 51, the water temperature sensor 52, the outside air temperature sensor 53, the vehicle speed sensor 54, the water supply adjustment switch 55, and the control unit 50. A spray section 146 for supplying water in the storage tank to the air flow path 30, a water supply path 43 for connecting the spray section 146 and the water storage tank 41, and a flow path provided in the water supply path 43. And an electromagnetic valve 145 that opens and closes.

  The spray unit 146 adjusts the opening of the water supply nozzle 142 that opens the water supply port 142 a in the air flow path 30, and the water supply port 142 a of the water supply nozzle 142, and configures the variable venturi part 147 in the air flow path 30. 148. The water supply port 142a of the water supply nozzle 142 is disposed so as to face substantially radially outward in the partition wall portion 33 (inner peripheral side) of the curved portion 30a of the air flow channel 30 (inner flow channel 30b '). The venturi piston 148 is disposed opposite the water supply port 142a, and reciprocates with a drive source (not shown) to change the opening degree of the water supply port 142a and the venturi diameter of the variable venturi portion 147.

  When the motorcycle 1 travels, the electromagnetic valve 145 opens the water supply path 43 and the venturi piston 148 strokes according to the vehicle speed, the air volume, and the like. As a result, the opening degree of the water supply port 142a and the venturi diameter of the variable venturi unit 147 change, an amount of water corresponding to the vehicle speed and the air volume is sucked from the water supply port 142a, and the water is supplied to the air flow path 30 in the form of a mist. Is done. At this time, the water supply port 142a of the water supply nozzle 142 opens into the negative pressure portion F formed on the inner peripheral side of the curved portion 30a, so that water can be satisfactorily sucked from the water supply port 142a. Vaporization of the supplied water is promoted by the high flow velocity traveling wind.

  The control unit 50 operates the solenoid valve 145 and the venturi piston 148 based on the detection information from the air flow meter 51, the vehicle speed sensor 54, the water temperature sensor 52 and the outside air temperature sensor 53, the position of the water supply adjustment switch 55, etc. Control the supply of water to 30. A specific example of the control is the same as that of the first embodiment, and the description thereof is omitted.
