JP 2000-95170 A

However, in a conventional saddle-ride type vehicle, even if the body frame portion constitutes the exterior of the body, additional exterior parts such as a body cover may be required. Also, in a saddle-ride type vehicle, the location of the fuel tank becomes an issue.
The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a saddle-ride type vehicle that does not require any additional exterior parts.

The saddle-type vehicle includes an engine, a hollow body frame section that passes above the engine, and a saddle-shaped fuel tank that is attached across the body frame section, the engine being a horizontal engine in which the axis of a cylinder section extends substantially horizontally in the fore-and-aft direction of the vehicle in a side view of the vehicle, an exhaust pipe of the engine extends rearward from an exhaust port provided on the underside of the cylinder section, a connecting tube that connects an air cleaner and a throttle device extends forward above the engine along an upper surface of the crankcase and an upper surface of the cylinder section, the body frame section has a portion in which the frame width narrows as it approaches the head pipe and the frame width becomes wider at the rear, a through hole is formed in the vicinity of the head pipe, and a support member that supports the fuel tank is attached to the through hole, the support member includes a support shaft and a pair of plate-shaped members, one of the plate-shaped members and the support shaft are welded together, the support shaft is passed through the through hole, and the other plate-shaped member and the support shaft are welded together a support shaft protruding outside the body frame section, a rubber being fitted onto the support shaft, the body frame section having an upper surface portion convex in an upwardly convex shape as viewed in a vehicle width direction cross section, and a first lower member constituting a lower surface portion by forming an air layer between the upper surface portion and the first lower member, the first lower member having an upwardly convex shape as viewed in a vehicle width direction cross section with an air layer formed between the upper surface portion and the first lower member, the engine being positioned below the first lower member, the engine having a cylinder extending from a crankcase and a fin provided on an outer periphery of the cylinder, the width of the cylinder not including the fin is narrower than the width of the first lower member above the cylinder, the fuel tank having a bottom plate formed in a convex shape so as to cover the convex shape of the body frame section, and a pair of extensions covering both side portions of the body frame section when mounted on the body frame section , inner end surfaces of the pair of extensions being in close contact with outer end surfaces of the rubber .

This specification contains the entire contents of Japanese patent application No. 2021-058050, filed on March 30, 2021.
The present invention includes a saddle-shaped fuel tank that straddles the vehicle body frame, so that the fuel tank enhances the vehicle's design and eliminates the need for additional exterior components.
In addition, because the width of the cylinder excluding the fins is narrower than the width of the body frame portion above the cylinder, engine heat is not easily transferred to the fuel tank.

In this embodiment, as shown in FIG. 1, a saddle-shaped fuel tank 41 is attached across a main tube (body frame portion) 18 that constitutes the exterior of the vehicle body.
According to this, the arrangement of the saddle-shaped fuel tank 41 enhances the design of the vehicle, and therefore, additional exterior parts such as a body cover are not required.

A fuel tank 41 is disposed on the upper side of the main tube 18. The fuel tank 41 is a hollow container that straddles the upper side of the main tube 18 and is disposed between the head pipe 15 and the seat 14. A battery 42 and the air cleaner 38 are disposed behind the fuel tank 41.
A fuel pump (not shown) disposed in the fuel tank 41 is connected to a fuel supply device 67 by a fuel hose.

FIG. 5 is an enlarged side view of the main tube 18, and FIG. 6 is a cross-sectional view taken along line VI-VI of FIG.
The main tube 18 is a hollow monocoque frame that constitutes the exterior of the vehicle body.
5, components such as the ABS modulator 25 and a battery 42 are disposed inside the main tube 18. The main tube 18 is capable of housing these components and also accommodates a fuel tank 41.

In this embodiment, as shown in FIG. 6, motorcycle 1 includes engine 11, main tube 18 that passes above engine 11, and saddle-shaped fuel tank 41 that is attached across the upper side of main tube 18.
The engine 11 includes a cylinder 86 extending forward from the crankcase 31. The cylinder 86 includes a plurality of fins 88 on its outer periphery.
A width W1 of the cylinder 86 not including the fins 88 is narrower than a width W2 of the main tube 18 above the cylinder 86. The width W2 corresponds to the width of the first lower member 55 that constitutes the lower surface of the main tube 18.

In this embodiment, the width W1 of the cylinder 86 not including the fins 88 is narrower than the width W2 of the main tube 18 above the cylinder 86. This makes it difficult for heat from the engine 11 to be transmitted to the fuel tank 41.
The air layer in the main tube 18 provides insulation against heat from the engine 11, thereby reducing the amount of evaporation in the fuel tank 41.

Further, the bottom plate 141 of the fuel tank 41 is formed into a convex shape 142 so as to cover the convex shape 118 of the main tube 18 .
The fuel tank 41 is integrally provided with a pair of extensions 143, 144 located on both sides of the main tube 18 when the fuel tank 41 is mounted on the main tube 18. The fuel tank 41 is saddle-shaped and is installed straddling the main tube 18.
4, the bottom surface of the main tube 18 is formed by a first lower member 55. The first lower member 55 has an upwardly convex shape.

Since the first lower member 55 has an upwardly convex shape, the heat of the engine 11 remains in the first lower member 55 and is therefore less likely to be transmitted to the fuel tank 41 .
5, components such as the ABS modulator 25 and the battery 42 are disposed inside the main tube 18. In this way, heat from the engine 11 is insulated by the components, and is less likely to be transmitted to the fuel tank 41.

The procedure for mounting the fuel tank 41 will now be described with reference to FIGS.
As shown in Fig. 7, a through hole 80 is formed in the main tube 18 near the head pipe 15. A support member 81 is attached to the through hole 80, as shown in Fig. 8.
9, the support member 81 includes a support shaft 82 and plate-like members 83 and 93. The procedure for attaching the support member 81 is to weld one plate-like member 83 to the support shaft 82, pass the support shaft 82 through the through-hole 80, and weld the other plate-like member 93 to the support shaft 82, as shown in FIG.
As shown in FIG. 8, the pair of plate-like members 83, 93 each have an extending portion 84, 94 at the front that extends inward in the vehicle width direction.

The support shaft 82 protrudes to the outside of the main tube 18 as shown in FIGS. 8 and 10, and a rubber 85 is fitted onto the support shaft 82 as shown in FIG.
As shown in FIG. 12, the fuel tank 41 is fitted from rear to front (in the direction of arrow A) so that the inner end faces of the extensions 143 , 144 of the fuel tank 41 come into close contact with the outer end face of the rubber 85 .
Finally, as shown in FIG. 13, the bracket 146 at the rear of the fuel tank 41 is fixed to the main tube 18 with bolts (not shown).

3, the frame width W of the main tube 18 narrows as it approaches the head pipe 15. A support member 81 that supports the fuel tank 41 is attached to a point P where the frame width W narrows.
The support member 81 includes plate-like members 83, 93 attached to the outer side of the body frame portion 18 in the vehicle width direction, and the plate-like members 83, 93 include extending portions 84, 94 at the front thereof that extend inward in the vehicle width direction.
According to this, even if the main tube 18 has a shape that narrows in the width direction toward the head pipe 15 as shown in FIG. 12, the existence of the extending portions 84, 94 makes it possible to reduce the inclination in the width direction, making it easy to attach the fuel tank 41.

In this embodiment, the frame width W3 has a wide portion Q, and the engine 11 is located below the wide portion Q. This makes it difficult for heat from the engine 11 to be transmitted to the fuel tank 41.

It should be noted that a saddle-shaped storage box for storing luggage and the like may be placed on the upper side of the main tube 18 in place of the fuel tank 41. The saddle-shaped storage box improves the design of the vehicle and eliminates the need for additional exterior parts such as a body cover. In either case, the saddle-shaped storage box can be easily installed by drilling a through-hole 80 in advance near the head pipe 15 of the main tube 18 as shown in Figure 7, and then simply attaching and welding the support member 81 shown in Figure 9 to the through-hole 80.

The above-described embodiment shows one mode in which the present invention is applied, and the present invention is not limited to the above-described embodiment.
In the above embodiment, a motorcycle 1 has been used as an example, but the present invention is not limited to this, and the present invention is applicable to three-wheeled saddle-ride vehicles having two front or rear wheels, and saddle-ride vehicles having four or more wheels.

[Configuration supported by the above embodiment]
The above embodiment supports the following configurations.

(Configuration 1) A vehicle equipped with an engine, a hollow body frame portion passing above the engine, and a saddle-shaped fuel tank mounted across the body frame portion,
The engine includes a cylinder extending from a crankcase and a fin provided on an outer periphery of the cylinder,
A saddle-type vehicle, wherein a width of the cylinder excluding the fin is narrower than a width of the vehicle body frame portion above the cylinder.
With this configuration, the width of the cylinder is narrower than the width of the body frame above the cylinder, so engine heat is less likely to be transmitted to the saddle-shaped fuel tank. Also, the air layer inside the hollow frame blocks heat, so engine heat is less likely to be transmitted to the fuel tank, and the amount of evaporation in the fuel tank is reduced.

(Configuration 2) A saddle-type vehicle as described in Configuration 1, characterized in that the body frame portion is a monocoque frame that forms the exterior of the vehicle body.

(Configuration 3) The saddle-type vehicle according to configuration 1 or 2, characterized in that the frame width of the body frame portion narrows as it approaches a head pipe, and a support member for supporting the fuel tank is attached to the narrowed portion.
According to this configuration, since the body frame portion has a portion where the frame width is narrowed, heat from the engine is less likely to be transmitted to the saddle-shaped fuel tank.

(Configuration 4) A saddle-type vehicle as described in Configuration 3, characterized in that the support member comprises a plate-shaped member attached to the outer side of the body frame portion in the vehicle width direction, and the plate-shaped member comprises an extension portion at the front that extends inward in the vehicle width direction.
With this configuration, even if the body frame portion narrows toward the head pipe, the plate-shaped member has a portion at the front that extends inward in the vehicle width direction, so that the inclination in the width direction can be reduced and a saddle-shaped fuel tank can be easily attached.

(Configuration 5) A saddle-type vehicle according to any one of configurations 1 to 4, wherein the bottom surface of the body frame portion has an upwardly convex shape.
With this configuration, engine heat remains on the bottom surface of the body frame, and is therefore less likely to be transferred to the saddle-shaped fuel tank.

(Configuration 6) A saddle-type vehicle according to any one of configurations 1 to 5, characterized in that a component is disposed inside the body frame portion.
With this configuration, engine heat is insulated by components within the body frame, making it more difficult for heat to be transmitted to the saddle-shaped fuel tank.
