Description

Technical Field

[0001] This invention relates to a straddle-type vehicle. Background Technology

[0002] In recent years, more and more people are conducting research and development related to improving fuel efficiency in order to ensure access to suitable, reliable, sustainable and advanced energy. In some motorcycles, fuel efficiency is improved by providing a central fairing that covers the front of the vehicle body from the outside in the vehicle width direction, thereby improving aerodynamic characteristics and allowing more airflow to contact the radiator (for example, see Japanese Patent No. 6488372). Summary of the Invention

[0003] In this technology related to improved fuel efficiency, there is room for improvement in the shape of the intermediate fairing from the viewpoint of improving the heat dissipation effect of the radiator. On the other hand, if the intermediate fairing is reduced in size, the structure disposed on the inner side of the intermediate fairing will be exposed, which may reduce the appearance.

[0004] The present invention provides a motorcycle-type vehicle that suppresses the degradation of appearance and improves the heat dissipation effect of the radiator. Furthermore, the present invention contributes to energy efficiency.

[0005] The first aspect of the present invention provides a motorcycle-type vehicle comprising: a frame having a head tube; an engine supported on the frame; and a center fairing covering the head tube from the outside in the vehicle width direction. The engine has a cylinder with a cylinder head cover. A cutout is formed on the center fairing that opens rearward when viewed from the side of the vehicle. The center fairing comprises: an upper center fairing positioned above the cutout when viewed from the side of the vehicle; and a lower center fairing positioned below the cutout when viewed from the side of the vehicle. The rear end of the upper center fairing is located further rearward than the rear end of the lower center fairing when viewed from the side of the vehicle. The upper center fairing covers at least a portion of the cylinder head cover from the outside in the vehicle width direction when viewed from the side of the vehicle.

[0006] According to the first design, by covering the cylinder head cover with an upper intermediate fairing, the degradation of appearance can be suppressed. Furthermore, since the rear end of the lower intermediate fairing is located at the front relative to the rear end of the upper intermediate fairing, the radiator's exhaust air is less likely to be obstructed by the lower intermediate fairing. Therefore, the degradation of appearance can be suppressed while improving the radiator's heat dissipation efficiency.

[0007] The second embodiment of the present invention, based on the first embodiment of the straddle-type vehicle, may also have the rear end of the upper intermediate fairing located in a position further forward than the midpoint between the axle of the front wheel and the axle of the rear wheel.

[0008] According to the second scheme, the size of the intermediate fairing in the front-rear direction can be reduced, thereby achieving the lightweighting of the intermediate fairing.

[0009] The third embodiment of the present invention, based on the first or second embodiment of the straddle-type vehicle, may also have a middle fairing having a partition that divides the front and rear of the cut.

[0010] According to the third scheme, the upper and lower intermediate fairings are connected by a partition, which can suppress the swaying of the upper and lower intermediate fairings and improve the rigidity of the intermediate fairing.

[0011] The fourth embodiment of the present invention, based on any of the first to third embodiments of the straddle-type vehicle described above, may also have the front end of the cut located in a position further forward than the central axis of the head tube when viewed from the side of the vehicle.

[0012] According to the fourth design, compared to a structure where the front end of the cut is located behind the central axis of the head tube when viewed from the side of the vehicle, the area of ​​the cut can be enlarged. This reduces air resistance caused by the central fairing when the vehicle tilts to the left or right, thus improving handling stability.

[0013] The fifth embodiment of the present invention, based on the third embodiment of the straddle-type vehicle, may also include a radiator, wherein the partition covers the radiator from the outside in the vehicle width direction.

[0014] According to the fifth option, the radiator cover is hidden when viewed from the side of the vehicle, thus improving the appearance of the motorcycle.

[0015] The sixth embodiment of the present invention, based on the third or fifth embodiment of the straddle-type vehicle, may also have an outer intermediate fairing located on the outer side in the vehicle width direction and an inner intermediate fairing located on the inner side in the vehicle width direction. A first opening located in front of the partition and a second opening located behind the partition are formed on the outer intermediate fairing. The inner intermediate fairing has a channel at the position where it overlaps with the first opening when viewed from the side of the vehicle.

[0016] According to the sixth design, the airflow introduced into the channel can escape directly to the outside of the central fairing through the first opening. Therefore, a portion of the airflow guided to the inside of the central fairing can be efficiently discharged.

[0017] The seventh embodiment of the present invention, based on the sixth embodiment of the above-mentioned straddle-type vehicle, may also be such that the imaginary straight line of the rear end of the lower middle fairing and the front end of the cut intersects with the imaginary line segment connecting the axle of the front wheel and the axle of the rear wheel when viewed from the side of the vehicle.

[0018] According to the seventh scheme, the driving air discharged through the first and second openings is unlikely to come into contact with the upper body of the occupants.

[0019] According to the present invention, it is possible to provide a straddle-type vehicle that suppresses the decline in appearance and improves the heat dissipation effect of the radiator. Attached Figure Description

The pivot frame 13 supports the swingarm to allow it to swing up and down. The downframe 14 extends downward and rearward from the lower part of the head tube 11, and is steeper than the main frame 12.

[0031] Figure 2 This is a right-side view of the front of the motorized two-wheeled vehicle, representing the embodiment.

[0032] like Figure 2 As shown, the steering mechanism 20 includes: a pair of left and right front forks 21; a top bridge 22 and a bottom bridge 23 mounted between the upper parts of the pair of front forks 21; and a steering rod (not shown) mounted between the top bridge 22 and the bottom bridge 23. The pair of front forks 21 axle support the front wheel 2 at their lower ends. A front fender covering the front wheel 2 is mounted on the pair of front forks 21. The top bridge 22 supports the handlebars 25. The steering rod (not shown) passes through the head tube 11 of the frame 10 and is supported on the frame 10.

[0033] Figure 3 This is a right-side view of the front of the motorized two-wheeled vehicle, showing a perspective view of the outer center fairing.

[0034] like Figure 3 As shown, the engine 30 is positioned below the main frame 12 and in front of the pivot frame 13. The engine 30 includes: a crankcase 31 that houses the crankshaft; and a cylinder 32 that engages with the front portion of the crankcase 31. The rear portion of the crankcase 31 is supported by the pivot frame 13.

[0035] The cylinder 32 includes: a cylinder block 33 protruding forward and upward from the crankcase 31; a cylinder head 34 connected to the cylinder block 33 from the front and upward; and a cylinder head cover 35 connected to the cylinder head 34 from the front and upward. The front part of the cylinder block 33 is supported on the descending frame 14. A piston is fitted and mounted inside the cylinder block 33. A combustion chamber is formed between the piston and the cylinder head 34. The piston is connected to the crankshaft via a connecting rod and a crankshaft pin. The reciprocating motion of the piston is converted into the rotational motion of the crankshaft via the connecting rod. The cylinder head 34 holds a valve train mechanism, which includes intake valves, exhaust valves, etc. The cylinder head cover 35 covers the valve train mechanism from the front and upward. The cylinder head cover 35 has a pipe connection portion 36 for connecting a pipe (not shown). The pipe connection portion 36 protrudes forward and upward. The pipe connection portion 36 is connected to an air filter via a pipe.

[0036] The radiator 40 is positioned in front of the cylinder 32. Viewed from the side in the vehicle width direction, the radiator 40 is located between the downlift frame 14 and the front fork 21, and is supported by the downlift frame 14. The radiator 40 is a crossflow radiator 40. The radiator 40 includes a radiator core 41 (see reference) for dissipating heat from the coolant circulating inside. Figure 7 The radiator 40 includes a first tank 42 and a second tank (not shown) adjacent to the ends of the radiator core 41 in the vehicle width direction. The radiator 40 is configured with a slightly forward-leaning posture so that the air-receiving surface of the radiator core 41 faces forward. Although not shown, the radiator core 41 is configured to intersect the center of the vehicle width and overlaps with the cylinder 32 of the engine 30 in frontal view. The radiator core 41 includes multiple tubes and cooling fins. The tubes extend in the vehicle width direction in frontal view, allowing the interior of the first tank 42 to communicate with the interior of the second tank.

[0037] The first tank 42 is disposed adjacent to the right end of the radiator core 41 at the right end of the radiator 40. The second tank is disposed adjacent to the left end of the radiator core 41 at the left end of the radiator 40. When viewed from the side, the first tank 42 and the second tank are arranged in a forward-leaning posture with their upper ends positioned further forward than their lower ends, with the length of the first tank 42 along the vertical direction. A cap 43 is detachably fitted to the upper end of the first tank 42 to close the cooling water inlet. A cooling water outlet is formed at the lower end of one of the first tank 42 and the second tank. A cooling water inlet is formed at the lower end of the other of the first tank 42 and the second tank.

[0038] like Figure 2 As shown, the body cover 50 covers the frame 10, etc. The body cover 50 is formed approximately symmetrically with respect to the center of the vehicle's width. The body cover 50 includes an upper fairing 51, a middle fairing 52, and a lower fairing 53.

[0039] The upper fairing 51 is positioned in front of the front fork 21 when viewed from the side. The upper fairing 51 covers the instrument panel 6, which is positioned in front of the head tube 11, and the instrument panel 91 surrounding the instrument panel 6. The upper fairing 51 is formed in a way that tapers forward when viewed from above and from the side. The upper surface of the upper fairing 51 extends rearward and upward from its front end, and extends rearward towards the outer side in the vehicle width direction. A windshield 92 is mounted on the upper surface of the upper fairing 51. A headlight unit 7 is positioned inside the upper fairing 51. The lens 7a of the headlight unit 7 protrudes to the left and right sides of the upper fairing 51, projecting light forward.

[0040] Figure 4 This is a front view of the motorized two-wheeled vehicle representing the implementation method.

[0041] like Figure 3 and Figure 4 As shown, a pair of left and right openings 56 are formed on the upper fairing 51. The openings 56 open forward below the lens 7a of the headlight unit 7. Each pair of openings 56 is connected to a pair of left and right air filter passages 94. The air filter passages 94 guide airflow towards the air filter. The air filter passages 94 are cylindrical and extend rearward from the openings 56. The interior of the air filter passages 94 communicates with the space in front of the vehicle through the openings 56.

[0042] like Figure 2 As shown, the center fairing 52 is symmetrically arranged on the left and right sides of the vehicle. The center fairing 52 covers the head tube 11 from the outer side in the vehicle width direction. In a side view, the center fairing 52 is positioned from the area in front of the front fork 21 to the area behind it. In a side view, the front part of the center fairing 52 is positioned below and behind the lens 7a and overlaps with the side of the upper fairing 51. The center fairing 52 extends rearward from its front part and then downward. In a side view, the center fairing 52 is spaced apart from the front wheel 2 and is positioned from above the front wheel 2 to the rear along the outer periphery of the front wheel 2. As the center fairing 52 extends rearward from its front part, in a side view, it overlaps with the front fork 21, the lower part of the head tube 11, the radiator 40, the downlift frame 14, the cylinder 32, and the main frame 12 from the outer side in the vehicle width direction.

[0043] like Figure 4 As shown, the middle fairing 52 and the upper fairing 51 cooperate to form the tire cover of the front wheel 2. A radiator 40 is arranged in the center of the tire cover.

[0044] like Figure 2 and Figure 3As shown, each intermediate fairing 52 has an outer intermediate fairing 60 located on the outer side in the vehicle width direction and an inner intermediate fairing 80 located on the inner side in the vehicle width direction. The intermediate fairing 52 is formed by combining the outer intermediate fairing 60 and the inner intermediate fairing 80. An air filter passage 94 passes through the space between the outer intermediate fairing 60 and the inner intermediate fairing 80 in the front-rear direction.

[0045] Figure 5 This is a right-side view of the right outer intermediate fairing of a pair of outer intermediate fairings in the embodiment.

[0046] like Figure 2 and Figure 5 As shown, the outer center fairing 60 forms a substantial whole of the portion of the center fairing 52 that can be visually recognized from the outside in the vehicle width direction. That is, in this embodiment, the entire inner center fairing 80 is covered by the outer center fairing 60 when viewed from the side, so in terms of vehicle appearance, the side view shape of the center fairing 52 is consistent with the side view shape of the outer center fairing 60.

[0047] The outer center fairing 60 has a cutout 61 that opens rearward in a side view and a turn indicator opening 64 that opens outward in the vehicle width direction. The cutout 61 extends forward from a position overlapping with the cylinder 32 of the engine 30 in a side view. The front end 61f of the cutout 61 is located forward of the central axis C of the head tube 11 in a side view. The outer center fairing 60 has an upper center fairing 65 located above the cutout 61 in a side view; and a lower center fairing 67 located below the cutout 61 in a side view. That is, the upper center fairing 65 and the lower center fairing 67 are separated from each other by the cutout 61. The shaft supporting the lamp body of the turn indicator 96 passes through the turn indicator opening 64. The turn indicator opening 64 extends through the lower center fairing 67 in the vehicle width direction. The turn indicator opening 64 is located forward and below the front end 61f of the cutout 61.

[0048] Describe in detail the shape of the incision 61 from a side view. For example... Figure 5As shown, the edge of the cutout 61 includes an upper edge 61a formed on the upper intermediate fairing 65 and a lower edge 61b formed on the lower intermediate fairing 67. The upper edge 61a has a rear portion 61a1 extending forward and downward from the rear end portion 65r of the upper intermediate fairing 65; and a front portion 61a2 extending forward and upward from the front end of the rear portion 61a1. The lower edge 61b has a rear portion 61b1 extending forward and upward from the rear end portion 67r of the lower intermediate fairing 67; a middle portion 61b2 extending forward from the front end of the rear portion 61b1 at a gentler slope than the rear portion 61b1; and a front portion 61b3 extending forward and upward from the front end of the middle portion 61b2 at a steeper slope than the middle portion 61b2. The entire rear portion 61b1 of the lower edge 61b is located below the rear portion 61a1 of the upper edge 61a. The middle portion 61b2 of the lower edge 61b is provided in such a way that it spans the connection between the rear portion 61a1 and the front portion 61a2 of the upper edge 61a in the front-rear direction. The front end portion 61f of the cut 61 is located below the rear end of the upper edge 61a and above the rear end of the lower edge 61b.

[0049] like Figure 2 and Figure 5 As shown, the rear end 65r of the upper center fairing 65 overlaps with the main frame 12 in a side view. The upper center fairing 65 extends from its rear end 65r to the front end of the center fairing 52. In a side view, the upper center fairing 65 covers at least a portion of the cylinder head cover 35 from the outside in the vehicle width direction. In this embodiment, the rear portion 61a1 of the upper edge 61a of the cutout 61 in the upper center fairing 65 overlaps with the pipe connection portion 36 in the cylinder head cover 35 in a side view. Moreover, the upper center fairing 65 overlaps with the main frame 12, the downlink frame 14, the head tube 11, and the front fork 21 in a side view. The rear end 65r of the upper center fairing 65 is located further rearward than the rear end 67r of the lower center fairing 67. In other words, under side-view observation, an imaginary straight line P extending vertically through the rear end 65r of the upper intermediate fairing 65 passes behind the rear end 67r of the lower intermediate fairing 67. The rear end 65r of the upper intermediate fairing 65 is the rear end of the intermediate fairing 52. The rear end 65r of the upper intermediate fairing 65 is located forward of the midpoint M between the axle of the front wheel 2 and the axle of the rear wheel 3 (refer to...). Figure 1 ).

[0050] The lower center fairing 67, when viewed from the side, is configured in a manner that does not overlap with the main frame 12 and the pivot frame 13. The rear end 67r of the lower center fairing 67 overlaps with the cylinder head 34. The rear end 67r of the lower center fairing 67 is positioned vertically at the same location as the radiator core 41 of the radiator 40. The lower center fairing 67 includes: a lower portion 68 extending downward from the rear end 67r along the outer periphery of the front wheel 2 when viewed from the side; and an upper portion 69 extending forward and upward from the rear end 67r along the outer periphery of the front wheel 2 to the front end of the center fairing 52 when viewed from the side. The upper portion 69 of the lower center fairing 67 overlaps with the cylinder head 34, the downlink frame 14, the radiator 40, and the front fork 21 when viewed from the side. The lower center fairing 67 overlaps with the radiator 40 in a manner that causes the upper end of the radiator 40 to protrude towards the upper center fairing 65 when viewed from the side.

[0051] like Figure 1 As shown, the imaginary straight line L passing through the rear end 67r of the lower central fairing 67 and the front end 61f of the cutout 61 passes below the main frame 12 in a side view and overlaps with the crankcase 31 and pivot frame 13 of the engine 30. The imaginary straight line L intersects with the imaginary line segment S connecting the axle of the front wheel 2 and the axle of the rear wheel 3 in a side view.

[0052] Figure 6 This is a perspective view of the area around the cutout of the central fairing in the motorized two-wheeled vehicle as seen from the right rear.

[0053] like Figure 2 and Figure 6 As shown, the outer intermediate fairing 60 also includes a partition 71 that divides the cutout 61 front and back. Thus, the cutout 61 has a first opening 62 located in front of the partition 71 and a second opening 63 located behind the partition 71. The partition 71 extends in a manner that connects the upper intermediate fairing 65 and the lower intermediate fairing 67. The partition 71 connects to the front portion 61a2 of the upper edge 61a and the front portion 61b3 of the lower edge 61b of the cutout 61. The partition 71 overlaps with the cover 43 of the radiator 40 when viewed from the side. The partition 71 overlaps entirely with the cover 43 when viewed from the side. However, the partition only needs to overlap with at least a portion of the cover 43 when viewed from the side. Alternatively, the partition may overlap with the coolant inlet when viewed from the side.

[0054] like Figure 3 and Figure 4 As shown, the inner center fairing 80 divides the tire cover. The inner center fairing 80 functions as a shield that directs driving airflow toward the radiator 40.

[0055] Figure 7This is a perspective view of the area around the cut of the middle fairing in the motorized two-wheeled vehicle of the embodiment, viewed from the right rear, showing the state after the outer middle fairing has been removed.

[0056] like Figure 6 and Figure 7 As shown, the inner intermediate fairing 80 has a channel 81. The channel 81, when viewed from the side, is positioned overlapping with the first opening 62 (see reference). Figure 2 and Figure 3 The passage 81 has an opening that opens inward in the vehicle width direction and communicates with the tire cover. The passage 81 extends outward in the vehicle width direction and connects with the opening edge of the first opening 62 of the outer intermediate fairing 60. Thus, the passage 81 communicates the space outside the tire cover and the intermediate fairing 52.

[0057] like Figure 2 As shown, the lower fairing 53 covers the lower part of the crankcase 31 from below and outward in the vehicle width direction. The lower fairing 53 is separate from the intermediate fairing 52. The lower fairing 53 has a bottom 54 located below the crankcase 31 in side view and an extension 55 extending forward and upward from the bottom 54 in side view. The front end of the bottom 54 is connected to the lower end of the lower part 68 of the lower intermediate fairing 67. The upper end of the extension 55 is connected to the rear end 67r of the lower intermediate fairing 67. The lower fairing 53 is positioned below the imaginary straight line L passing through the rear end 67r of the lower intermediate fairing 67 and the front end 61f of the cutout 61 in side view (see reference). Figure 1 ).

[0058] As explained above, the motorized two-wheeled vehicle 1 of this embodiment includes a center fairing 52, which has an upper center fairing 65 positioned above the cutout 61 in side view and a lower center fairing 67 positioned below the cutout 61 in side view. The rear end 65r of the upper center fairing 65 is positioned further rearward than the rear end 67r of the lower center fairing 67 in side view, and the upper center fairing 65 covers at least a portion of the cylinder head cover 35 from the outside in the vehicle width direction in side view. According to this structure, by covering the cylinder head cover 35 with the upper center fairing 65, a decrease in aesthetics can be suppressed. Furthermore, since the rear end 67r of the lower center fairing 67 is positioned forward relative to the rear end 65r of the upper center fairing 65, the exhaust air of the radiator 40 is less likely to be obstructed by the lower center fairing 67. Therefore, a decrease in aesthetics can be suppressed and the heat dissipation effect of the radiator 40 can be improved.

[0059] The rear end 65r of the upper intermediate fairing 65 is located forward of the midpoint M between the axle of the front wheel 2 and the axle of the rear wheel 3. This structure allows for a reduction in the longitudinal dimension of the intermediate fairing 52, thus achieving a lighter intermediate fairing 52.

[0060] The intermediate fairing 52 has a partition 71 that divides the cutout 61 in front and behind. According to this structure, the upper intermediate fairing 65 and the lower intermediate fairing 67 are connected by the partition 71, thereby suppressing the swaying of the upper intermediate fairing 65 and the lower intermediate fairing 67 and improving the rigidity of the intermediate fairing 52.

[0061] The front end 61f of the cutout 61, when viewed from the side, is located forward of the central axis C of the head tube 11. This structure allows for a larger area of ​​the cutout 61 compared to a structure where the front end of the cutout 61 is located rearward of the central axis C of the head tube 11 when viewed from the side. This reduces air resistance caused by the central fairing 52 when the vehicle tilts to the left or right, thus improving handling stability.

[0062] The partition 71 covers the radiator 40 cover 43 from the outside in the vehicle width direction. According to this structure, the radiator 40 cover 43 is hidden when viewed from the side, thus improving the appearance of the motorized two-wheeled vehicle 1.

[0063] The center fairing 52 has an outer center fairing 60 located on the outer side in the vehicle width direction and an inner center fairing 80 located on the inner side in the vehicle width direction. A first opening 62 located in front of the partition 71 and a second opening 63 located behind the partition 71 are formed on the outer center fairing 60. The inner center fairing 80 has a channel 81 at a position overlapping the first opening 62 when viewed from the side. According to this structure, the airflow introduced into the channel 81 can escape directly to the outside of the center fairing 52 through the first opening 62. Therefore, a portion of the airflow guided to the inner side of the tire cover of the center fairing 52 can be efficiently discharged.

[0064] The imaginary straight line L, formed by the rear end 67r of the lower central fairing 67 and the front end 61f of the cutout 61, intersects, in a side view, the imaginary line segment S connecting the axle of the front wheel 2 and the axle of the rear wheel 3. This structure makes it difficult for the airflow exiting through the first opening 62 and the second opening 63 to contact the upper body of the occupant.

[0065] It should be noted that the present invention is not limited to the embodiments described above with reference to the accompanying drawings, and various modifications are possible within its technical scope.

[0066] For example, in the above embodiment, the entire inner center fairing 80 is covered by the outer center fairing 60 when viewed from the side, but this structure is not limited to this. That is, the inner center fairing can be visually identifiable from the side view of the vehicle exterior. In this case, the cutout of the center fairing can be formed in the inner center fairing, and the inner center fairing can be included in at least one of the upper center fairing and the lower center fairing.

[0067] Furthermore, in the above embodiment, the upper intermediate fairing 65 only covers a portion of the cylinder head cover 35 when viewed from the side, but this is not a limitation. The upper intermediate fairing may also cover the entire cylinder head cover when viewed from the side.

[0068] Furthermore, each outer intermediate fairing 60 can be formed from a single plate or from multiple plates. For example, the outer intermediate fairing 60 can be formed from a portion having a cutout 61 and a portion arranged to surround the portion having the cutout 61 by separate plates.

[0069] Furthermore, without departing from the spirit of the invention, the constituent elements in the above embodiments may be appropriately replaced with well-known constituent elements.
