Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the arrangement structure of an oil cooler hose for a motorcycle.

(Prior art) A radiator is disposed facing forward in front of an engine and is composed of a core part and tank parts on both left and right sides of the core part, and is close to the inner end of the tank part from the front of the outer end of the tank part of the radiator. A motorcycle is known that is equipped with a guide plate that extends out and guides the running wind in front of the tank part to the core part (Utility Model No. 59-114414).
Publication No.).

(Problem to be solved by the invention) When attempting to install an oil cooler connected to the engine side with an oil cooler hose above the radiator in such a motorcycle, it is necessary to create a separate space for installing the oil cooler hose. There are various restrictions on space layout, especially for motorcycles equipped with a fairing that covers the front and sides of the vehicle body. This may cause problems such as oxidation.

The present invention was devised to solve the above-mentioned problems, and the purpose of the present invention is to allow the oil cooler hose to be installed without having to specifically secure a space for the oil cooler hose. To provide an arrangement structure for an oil cooler hose for a motorcycle that is advantageous in terms of space layout and can make the fairing compact in the case of a vehicle equipped with a fairing.

(Means for Solving the Problems) In order to achieve the above object, the present invention connects the oil cooler hose 71 to the engine 27 side through a space 73 defined by the guide plate 51 and the tank portion 41 of the radiator 37. I did it like that.

(Function) Guide plate 51 and tank portion 41 of radiator 37
An oil cooler hose 71 is disposed using a dead space 73 defined by the above. Therefore, there is no need to specifically secure a space for arranging the oil cooler hose 71, which is advantageous in terms of space layout. Further, in the case where the fairing 81 is attached, the fairing 81 can be made compact.

After being cooled in the core section 39, it reaches the left tank section 41B, and is then fed via the hose 43 to the water pump 45 on the side of the engine 27.

47 is a radiator grill, and the radiator grill 47 is arranged on the front side of the radiator 37.

The radiator grill 47 includes a protector 49 disposed in front of the core portion 39 and a protector 49.
a traveling wind guide plate 51 connected to both left and right sides of the
Upper and lower connecting plates 53 and 55 connect the upper and lower edges of the guide plate 51 and the upper and lower edges on both sides of the protector 49, and upper and lower connecting plates 53 and 55 that extend rearward from the upper edge of the protector 49 and are mounted on the upper surface of the radiator 37. It consists of an upper plate 57 and the like on which it is placed.

To attach the radiator grille 47 to the vehicle body, fit the protrusions 59 on the upper surface of the radiator 37 into the locking holes 61 of the upper plate 57, place the upper plate 57 on the upper surface of the radiator 37, and connect the connecting plates 55 on the lower side. This is done by locking a claw body protruding rearward to the lower surface side of the radiator 37.

The guide plate 51 has an outer end 51A connected to the outer end 4 of the tank, as shown in FIG.
1C, and the inner end 51B is formed to extend in an inclined manner so as to be close to the tank inner end 41D,
It is configured so that the traveling wind that hits the tank parts 41, 41 on both sides of the radiator 37 is guided to the core part 39.

A notch 63 is formed at the upper part of the guide plate 51, a notch 65 is formed at a part of the lower connecting plate 55 that protrudes rearward from the guide plate 51,
A notch 67 is formed in the lower part of the protector 49.

Reference numeral 69 denotes an oil cooler, and the oil cooler 69 is disposed above and in front of the radiator 37, and is supported by a stay extending vertically from the meter unit 21. Oil is fed from the oil pan to the right supply port of the oil cooler 69 via the oil cooler hose 71A, and after being cooled by the oil cooler 69, the oil is passed from the left outlet via the oil cooler hose 71 to the oil filter and the engine side. is supplied to

The oil cooler hose 71 is shown in FIGS.
As shown in the figure, it is disposed through a space 73 defined between the guide plate 51 and the tank portion 41. In the embodiment, an oil cooler hose 71 is passed through the cutouts 63, 65 and the space 73, and a screw 7 is installed on the side of the tank portion 41.
The oil cooler hose 71 is held in the space 73 by the holder 77 attached at 5 and 75.
