Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tricycle, etc., in which a radiator is arranged in the body frame in front of the engine.

(Prior Art) In a radiator for a tricycle or the like, it is known to provide a wind guide plate on the front surface of the radiator so that traveling wind can easily hit the radiator. At that time, the applicant had previously proposed that the cooling effect of the radiator be improved by forming the air guide plate vertically so that the mud that had adhered to the air guide plate due to vibrations during driving would fall off (Japanese Patent Application No. 57-177755) issue). However, if the baffle plate is simply formed vertically, mud thrown up by cars running in front or to the side will adhere to the radiator, which will impair the cooling effect of the radiator.

(Purpose of the invention) The present invention was made based on the above circumstances, and its purpose is to prevent mud from adhering to the radiator and improve the cooling effect of the radiator.

(Description of Examples) An example in which the present invention is applied to a three-wheeled motor vehicle for traveling on rough terrain will be described.

In the figure, reference numeral 1 denotes a vehicle body frame, which has a main pipe 3 extending rearward from a steering shaft tube 2 and a down tube 4 extending obliquely downward. A water-cooled type 2 is installed in the space surrounded by the main pipe 3 and down tube 4.
A cycle engine 5 is mounted. A front fork 6 is rotatably supported on the steering shaft tube 2. At the lower end of this front fork 6 is a front wheel 7 equipped with an ultra-low pressure so-called balloon tire.
is attached, and this front wheel 7 is covered by a front fender 8. Reference numeral 9 denotes a pair of left and right rear arms swingably supported by the vehicle body frame 1;
A pair of left and right rear wheels 10 equipped with balloon tires are attached to the rear end.

A pair of left and right radiators 11, 11a, and 11b are provided on both left and right sides of the down tube 4, located behind a ventilation space 12 provided above the front wheel 7. A wind blower 13 is installed in front of this radiator 11.
is installed. The airflow fan 13 includes a plurality of vertically elongated airflow plates 14, each of which has its front edge inclined toward the center of the vehicle body and faces the ventilation space 12. The wind guide plate 14 is formed to have a short length on the side toward the center of the vehicle body, so that the traveling wind sufficiently hits the radiator 11 on the center side of the vehicle body. 15 is a wind blower located below the headlight 16 and provided between the front forks 6;
The running wind passing through the ventilation space 12 is transferred to the radiator 11.
lead in a direction. Note that the radiator 11 is located approximately within the width of the front fork 6, which, together with being located behind the front fender 8, makes it difficult for mud to adhere to the radiator 11.

On the other hand, a plurality of running air intakes 17 are provided at a portion of the front fender 8 facing the radiator 11 to communicate the ventilation space 12 with the rear of the front fender 8 . A wall portion 18 extending rearward is integrally provided at the upper edge of the running wind intake 17. The running wind guided to the running wind intake 17 flows along the wind guide plate 14 tilted toward the center of the vehicle body, and hits the radiator 11.

According to such a configuration, mud thrown up by a car running in front is blocked by the air guide plate 14 and is less likely to adhere to the radiator 11. Furthermore, the front edge of the air guide plate 14 is tilted toward the center of the vehicle body to create a ventilation space 12 above the front wheels 7.
Since the vehicle faces the road, the mud thrown up by cars running on the side is also blocked by the wind guide plate 14, while the wind passing through the ventilation space 12 is guided to the wind blower 15 and the wind intake 17 to the radiator. 11, so the cooling effect of the radiator is improved.

(Effects of the invention) As described above, the present invention provides a plurality of vertically elongated air guide plates on the front of the radiator, and tilts the front edge of the air guide plates toward the center of the vehicle body so as to face the ventilation space above the front wheels. Therefore, the mud thrown up by cars running in front or to the side is blocked by the air guide plate and is difficult to adhere to the radiator, while the wind passing through the ventilation space hits the radiator, effectively cooling the radiator. There is.
