According to this bulletin, the vehicle is provided with a driving unit for driving, which extends longer in the longitudinal direction (front-rear direction) of the vehicle body, and can be swung in a manner such that the rear side thereof can be shaken ^ Side axles (supported rotatably) on the vehicle body and rear wheels are arranged on the center in the width direction of the vehicle body and supported on the rear of the drive unit. The drive unit includes a driving source for driving ; The radiator is arranged from the center of the width direction of the vehicle body to one side, and cooling water for cooling the driving source is cooled; and the fan is provided with It can rotate around the axis extending in the width direction of the vehicle body, and g is placed inside the radiator in the width direction of the vehicle body, and air outside the vehicle width direction can be supplied to the radiator. The fan is provided with a plurality of blades arranged in a circumferential direction around the axis of the fan. The air outside the rotation of the fan is attracted to the blades through the core portion of the radiator from the radiator. The internal space of the track is rotated, and the air is discharged outside the diameter direction through the above-mentioned blades. By the dagger, the external air can be supplied to the radiator, and the cooling water in the radiator is cooled. .doc 1241249 When the vehicle is driving by the driving force output from the driving source, the driving source is driven back due to the driving force output. However, due to the exhaustion of the external space, the fan When supplied to the radiator, the water in the cold part is cooled, and the above driving source is cooled by this cooling water τ 1 so that the lettuce of this driving source can be prevented. In addition, to solve the problem that the invention wants to solve, in addition, to more surely prevent the drive source accompanying the spring cylinder wide cylinder α + 卞 丨 from being driven by the vehicle in the morning, the temperature of the radiator can be increased. The cooling capacity of the cooling water in the radiator is further increased. The radiator is configured as a self-propelled vehicle. However, if the radiator is only increased, as described above, in a saddle-type vehicle, the center of the width direction of the body is biased to one side. Therefore, when the shape of the vehicle is inclined while driving, the lower end of the radiator is likely to contact the road surface, that is, the inclination angle may become smaller. The present invention is based on the above situation, so the object of the present invention is to provide a The saddle-type vehicle is more reliable in water cooling device and the saddle-type vehicle equipped with the water-cooling device when it is driven by the temperature of the drive source, and the above-mentioned drive source is to prevent this high temperature, and even here In this case, a sufficiently large vehicle tilt angle can also be obtained.

This mixed gas is burned by the discharge of the ignition plug 41, and the combustion gas is discharged as the exhaust gas C through the exhaust gas f39. The driving force generated by the combustion in the steam red 34 is output from the crank car, and can be transmitted to the rear wheels 10 through the transmission mechanism 27 (FIG. 3), etc., so that the vehicle can travel. For the crankshaft 33, The water pump 48 is linked with the fan 51 and rotates in the direction of arrow A 95272.doc -21-1241249. The water pump 48 sucks the cooling water 44 in the radiator 46 through the first cooling water pipe 74, and supplies the cooling water 44 to the lower part of the water jacket in the cylinder 34 through the second cooling water pipe 75. The cooling water 44 flowing toward the upper part of the water jacket 0 is returned to the radiator 46 through the thermostat 77 and the third cooling water pipe. In the above-mentioned political heat, 46, the cooling water 44 flows downwards from the upper box 56 to the "meal body 57" and flows downward through the water passage pipes 60 of the core 58 to the above-mentioned fan 5 1 The air b is sucked from the outside of the radiator 46, and the jade gas B cools the cooling water 44 in each of the water passing pipes 60 through the radiating fins 6 丨 of the core portion 58. The cooled cooling water 44 is thereafter supplied to the water jacket 47 in the cylinder 34 again by the water pump 48, the first cooling water pipe 74, and the second cooling water pipe as described above, so that the cylinder 34 is cooled. According to the above configuration, the center 4 of the core portion 58 of the radiator 46 in the vertical direction is at the same position as the end of the rotation locus 86 of the blade 85 of the fan 51 in the longitudinal direction of the vehicle body 2 or at the same position as the rotation The front end of the track 86 is more forward, and the rear end of the central portion in the vertical direction of the core portion 58 and the rear end of the rotation track% in the length direction of the vehicle body 2 are located at substantially the same position, or located at the same position as the above. The rear end of the rotation track 86 is further rearward. Therefore, in the above-mentioned embodiment, the entirety of the fan 51 in the longitudinal direction of the vehicle body 2 is in the axial direction of the fan 51 and is opposed to the core portion 58 of the radiator 46. Therefore, by using the fan 51, it is possible to Supply sufficient air b to the core portion 5 8 with a heat dissipation of 4 6 as described above. With the radiator 4 6, the cooling water 44 can be sufficiently cooled, and the cooling water 44 can more surely prevent the height of the driving source 26 from being 95272. .doc -22- 1241249 Warming. Also, in the above embodiment, the central end of the central portion 58 of the radiator 46 in the vertical direction and the front end of the rotation locus 86 of the blade 85 of the fan 51 in the longitudinal direction of the vehicle body 2 are located at substantially the same position, or Located at a position more forward than the front end of the rotation track 86, and the rear end of the central portion in the vertical direction in the core portion 58 is located at approximately the same position as the rear end of the rotation track 86 in the length direction of the vehicle body 2, or It is located at a rear position compared with the rear end of the rotation track 86. Therefore, the shape of the radiator 46 is likely to become larger in the length direction of the vehicle body 2. However, the size in the vertical direction can be suppressed to be small. The above radiator 46 can ensure a specific vehicle. Thereby, when the vehicle 1 is turning at an angle while driving, the lower end portion of the radiator 46 can be prevented from contacting the road surface 25. That is, "the effect" can be obtained that not only the surface temperature of the drive source 26 can be more reliably prevented, but also the tilt angle of the vehicle can be sufficiently increased even in this case. In the above-mentioned embodiment, the lower end of the central portion 5 8 of the vehicle body 2 in the longitudinal direction of the core portion 58 of the radiator 与 is located at substantially the same height as the inner peripheral surface 88 of the rotation locus 86 of the blade 85, or at The position is higher than the lower end of the inner peripheral surface 88 of the rotation locus 86. Here, in the above-mentioned embodiment, when the lower end of the central portion in the longitudinal direction of the vehicle body 2 in the core portion 58 of the radiator 46 and the lower end of the inner peripheral surface 88 of the rotation track 86 of the blade 85 are located at approximately the same height, the above At least the lower part of the fan 51 is substantially entirely in the axial direction of the fan 51, and is opposed to the core portion 58 of the radiator 46, and can supply sufficient air b to the core portion 58, thereby dispersing 95272.doc -23-1241249. Heater 46: The cooling water 44 is sufficiently cooled, so that cooling the water material can more reliably prevent the drive source 26 from becoming hot. In the above-mentioned embodiment, the lower end of the central portion in the longitudinal direction of the vehicle body 2 in the core portion 58 of the radiator 46 and the lower end of the inner peripheral surface of the rotation track% of the blade 85 are located at substantially the same degree, or located at the same position as the rotation The lower end of the inner peripheral surface 88 of the track% is higher than the upper position, so that the lower end of the core portion 58 of the above-mentioned heat dissipation state 46 can be prevented from being too low, and a special vehicle can be ensured under this radiator. 1 When turning at an angle, it is possible to prevent the lower end of the radiator 46 from contacting the road surface 25. That is, not only the temperature of the drive source 26 can be prevented more reliably, but also the tilt of the vehicle can be sufficiently increased even in this case. Here, the radiator 46 is biased outward from the rear wheel 10, and at this time, the larger the width dimension of the rear wheel 10, the easier the radiator 46 is biased to the outside from the rear wheel 10. Therefore, when When the vehicle is moving and turning at an angle, the lower end of the radiator 46 is more likely to contact the road surface 25, which may make the inclination angle smaller. Therefore, in the above embodiment, the core portion 58 of the radiator 46 is made vertical The front end of the central portion in the direction is located at substantially the same position as the front end of the rotation track 86 of the blade 85 of the fan 51 in the length direction of the vehicle body 2, or is located more forward than the front end of the rotation track 86, and the core portion 58 is The rear end of the central portion in the middle vertical direction is located at substantially the same position as the rear end of the rotation track 86 in the longitudinal direction of the vehicle body 2 or at a position more rearward than the rear end of the rotation track 86. "Same as the above | Effect", but this "Effect" is particularly beneficial for the vehicle 1 with the rocking drive 95272.doc -24-1241249. In addition, the vehicle 1 is not limited to the above embodiment, and may be an automatic three-wheeled vehicle or a snow removing vehicle. In addition, the loading arm 9 and the work unit 24 may be two stand-alone units. Further, the fuel supply device 38 may be a person who supplies fuel through a fuel injection room. The drive source 26 may be a motor. The fan 51 may have a different axis from the crankshaft 33, and may be driven by another driving mechanism. [Schematic description]
