Description

Technical Field

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

[0002] Japanese Patent Publication No. 9-301244 discloses a motorized two-wheeled vehicle with a bracket. The bracket is disposed in front of the head tube. The bracket is used for loading luggage. Summary of the Invention

[0003] In Japanese Patent Publication No. 9-301244, the bracket has a backrest support portion. The backrest support portion is bolted to the front fork via a bracket. Thus, the bracket is fixed to the front fork. In this case, when luggage is loaded onto the mounting portion of the bracket, the torque generated by the loaded luggage acts on the front fork supporting the bracket. As a result, there is a problem that the torque generated on the vehicle body when luggage is loaded onto the bracket increases.

[0004] The purpose of this invention is to solve the above-mentioned technical problems.

[0005] The present invention provides a straddle-type vehicle having a head tube and a bracket, wherein the head tube constitutes the vehicle body; the bracket is disposed in front of the head tube and is capable of carrying luggage; the straddle-type vehicle has an instrument support and a mounting part, wherein the instrument support is located in a position further forward than the head tube and further rear than the bracket, and is used to mount an instrument; the mounting part is used to mount the bracket to the vehicle body, and the mounting part is at least mounted on the instrument support.

[0006] Therefore, the connection point between the bracket and the instrument support is close to the bracket. As a result, the torque exerted on the vehicle body when loading luggage onto the bracket can be reduced.

[0007] In this embodiment of the invention, the straddle-type vehicle also has a top beam pivotally supported on the head tube, the upper end of which is located above the instrument support behind it.

[0008] Therefore, when a rider in a straddle-mounted vehicle looks ahead, the mounting section is not easily visible due to the upper beam. As a result, the appearance of the straddle-mounted vehicle can be improved.

[0009] In this invention, the straddle-type vehicle also has a headlight disposed in front of the head tube, and the bracket has a loading section and an extension, wherein the loading section is used to carry the luggage; the extension extends upward from the loading section, and the headlight is located below the loading section.

[0010] This prevents the bracket from obstructing the headlight's light distribution.

[0011] In this invention, the instrument is fixed to the instrument support behind the loading section, the loading section having a shape that expands as it approaches the instrument, and the bracket also having a bent portion that extends from the rear end of the loading section toward the instrument support, bending inward from the side of the instrument toward the rear in the width direction of the straddle vehicle.

[0012] This ensures sufficient space for instrument configuration while mounting the bracket and instrument onto the instrument support.

[0013] In this invention, the bracket further has a straight section that extends rearward in a straight line from the rear end of the loading section and is connected to the bent section, and a mounting support for mounting a wind deflector is installed on the straight section.

[0014] This allows for the installation of a windshield at the front of the motorcycle while ensuring space for the instrument panel.

[0015] In this invention, the instrument support is mounted on the upper beam and, when viewed from above, is positioned further forward than the upper beam.

[0016] This further reduces the torque on the vehicle body when loading luggage onto the rack.

[0017] In this invention, the straddle-type vehicle also has a lower beam pivotally supported on the head tube, and the plurality of mounting portions are a first mounting portion and a second mounting portion, wherein the first mounting portion has a first fastening portion for securing the bracket to the instrument support; and the second mounting portion has a second fastening portion for securing the bracket to the lower beam.

[0018] Therefore, since the bracket is fastened to the upper and lower parts of the vehicle body, it can be firmly fixed to the vehicle body. In addition, since the bracket and the vehicle body are not connected and fixed together, it is not easy for the fasteners to loosen.

[0019] In this invention, the bracket has a frame with a rod-shaped component, and the mounting portion has a planar portion formed by making the rear end of the bracket planar, the planar portion being in contact with the surface of the instrument support member.

[0020] This allows for both improved mountability of the bracket relative to the instrument support and improved appearance of the mounting section. Attached Figure Description

[0039] Reference Figures 1-5 The characteristic structure of the motorized two-wheeled vehicle 10 configured as described above will be explained. The characteristic structure refers to the structure related to the mounting of the bracket 50 to the vehicle frame 18. As mentioned above, the bracket 50 is disposed in front of the head tube 22 that constitutes the vehicle frame 18. The bracket 50 is capable of carrying luggage.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, an instrument support 120 is disposed between the head tube 22 and the bracket 50. An instrument 46 is mounted on the instrument support 120. The instrument support 120 is located in front of the head tube 22 and behind the bracket 50. The instrument support 120 is a flat plate. The instrument support 120 is fixed to the bottom surface of the top beam 24. The instrument support 120... Figure 5 In a top-down view, it is located further forward than the top beam 24. Therefore, as... Figure 2 As shown, the upper end 24a of the top beam 24 is located behind and above the instrument support 120. The instrument support 120 tilts downwards as it approaches the head tube 22. The tilt angle of the instrument support 120 relative to the horizontal direction is approximately the same as the tilt angle of the instrument 46 relative to the horizontal direction.

[0041] In the instrument support 120, a portion forward of the top beam 24 has mounting holes (not shown) formed along the left and right sides. The instrument 46 is fixed to the instrument support 120 with its mounting hole on the right side inserted through the right-side mounting hole. The accessory socket 48 is fixed to the instrument support 120 with its mounting hole on the left side inserted through the left-side mounting hole.

[0042] The bracket 50 is constructed by connecting rod-shaped components 122, such as cylindrical tubes. The bracket 50 has a loading section 124 and an extension 126. The loading section 124 extends horizontally above the headlight 42. Luggage is placed on the loading section 124. The extension 126 extends upward from the rear of the loading section 124. When luggage is placed on the loading section 124, the extension 126 functions as a backrest for the luggage.

[0043] Loading unit 124 Figure 4 In a top-down view, it has a shape that expands in width along the vehicle width direction as it approaches the instrument panel 46. The left and right rear ends of the loading section 124 extend toward the instrument panel support 120. More specifically, the rod-shaped member 122 forms the outer frame 128 of the loading section 124. The left and right ends of the rod-shaped member 122 form the left and right rear ends of the loading section 124. That is, the left and right ends of the rod-shaped member 122 at... Figure 4 In a top-view observation, each part has a straight section 130 and a bent section 132. Each straight section 130 extends in a straight line towards the rear and outward in the vehicle width direction. Each bent section 132 bends inward in the vehicle width direction at the rear end of the straight section 130 and extends rearward.

[0044] The rear ends of each bent portion 132 extend to the left and right ends of the instrument support 120. The rear ends of each bent portion 132 are configured as planar portions 134. Each planar portion 134 makes surface contact with the upper surface of the instrument support 120. Threaded holes (not shown) are formed in each planar portion 134. Threaded holes (not shown) are formed on both the left and right sides of the instrument support 120. The threaded holes of each planar portion 134 communicate with the threaded holes of the instrument support 120. Each planar portion 134 is fastened to the instrument support 120 by engaging the threaded holes of the planar portions 134 with the threaded holes of the instrument support 120 using screw members 136 (first fastening parts). Therefore, the bracket 50 is mounted to the instrument support 120 via each planar portion 134 and each screw member 136.

[0045] Thus, the first mounting portion 144 for mounting the bracket 50 to the vehicle body frame 18 (top beam 24) is constituted by each flat portion 134 and each screw component 136. Furthermore, in Figure 2 In a side view, a first mounting portion 144 is formed at the front end of the straight portion 130 of the bracket 50 that bends downward. The first mounting portion 144 coincides with the headlight 42 in the height direction.

[0046] Wind deflector supports 52 are mounted on the left and right straight sections 130. Each wind deflector support 52 extends upward from each straight section 130. The front end of each wind deflector support 52 is slightly inclined upward and backward. A wind deflector 54 is mounted to the front end of each wind deflector support 52 by a plurality of screw components 138. Thus, the wind deflector 54 is positioned behind the extension 126.

[0047] A cylindrical tube or similar rod-shaped component 56 is connected to the rear end of each windshield support member 52. The rod-shaped component 56 extends along the width direction in front of the handlebar 36 and above the instrument panel 46 and instrument panel support member 120. The left and right ends of the rod-shaped component 56 are fixed to the rear end of each windshield support member 52 in a manner that runs along the rear end of each windshield support member 52. Specifically, the left and right ends of the rod-shaped component 56 are supported on the rear end of each windshield support member 52 in a manner that is located further rearward than the rear end of each windshield support member 52.

[0048] A pair of bracket support portions 140 are connected to the bracket 50. The bracket support portions 140 extend downward from the bottom of the loading section 124, passing the outer side of the headlight 42 in the vehicle width direction, and are connected to the bottom beam 26. Specifically, the bracket support portions 140 are composed of rod-shaped components such as cylindrical tubes. A pair of bracket support portions 140... Figure 3 In a frontal view, the load-bearing section 124 extends downwards and outwards from the left and right sides of its bottom in the vehicle width direction. The pair of left and right bracket support portions 140 bend inwards in the vehicle width direction at the outer portion of the headlight 42, and extend inwards in the vehicle width direction. Thus, the pair of left and right bracket support portions 140 extend downwards and outwards from the left and right sides of the bottom of the load-bearing section 124, extending to the front of the bottom beam 26. That is, in Figure 3 In the front view, the pair of left and right bracket support portions 140 extend downward from the bottom left and right sides of the loading section 124, surrounding the headlights 42 from the outside in the vehicle width direction. Furthermore, each bracket support portion 140... Figure 1 and Figure 2 In a side view, it extends obliquely downward and backward from the bottom of the loading section 124.

[0049] A threaded hole (not shown) is formed at the lower end of the bracket support portion 140. Additionally, a threaded hole (not shown) is formed on the base beam 26. The threaded hole at the lower end of the bracket support portion 140 communicates with the threaded hole in the base beam 26. Therefore, by screwing the screw component 142 (second fastening portion) into these threaded holes, the bracket support portion 140 is fastened to the base beam 26. Thus, the bracket 50 is mounted to the base beam 26 via the lower end of the bracket support portion 140 and each screw component 142.

[0050] Thus, the lower end of the bracket support portion 140 and each screw component 142 constitute a second mounting portion 145 for mounting the bracket 50 to the vehicle frame 18 (bottom beam 26).

[0051] Furthermore, the present invention is not limited to the embodiments described above, and various structures can be adopted without departing from the spirit of the present invention.

[0052] The invention described below can be mastered based on the above-described embodiments.

[0053] The present invention is a straddle-type vehicle (10) having a head tube (22) and a bracket (50), wherein the head tube constitutes a body (18); the bracket is disposed in front of the head tube (22) and is capable of carrying luggage; the straddle-type vehicle (10) has an instrument support (120) and mounting parts (144, 145), wherein the instrument support is located in front of the head tube (22) and behind the bracket (50) for mounting an instrument (46); the mounting parts are used to mount the bracket (50) to the body (18), and the mounting parts (144, 145) are at least mounted on the instrument support (120).

[0054] Therefore, the connection point between the bracket and the instrument support is close to the bracket. As a result, the torque exerted on the vehicle body when loading luggage onto the bracket can be reduced.

[0055] In this embodiment of the invention, the straddle vehicle (10) also has a top beam (24) pivotally supported on the head tube (22), the upper end (24a) of which is located above the instrument support (120) behind it.

[0056] Therefore, when a passenger in a motorcycle is looking ahead, the mounting section is not easily visible due to the upper beam. As a result, the appearance of the motorcycle is improved.

[0057] In this embodiment of the invention, the straddle vehicle (10) also has a headlight (42) disposed in front of the head tube (22), and the bracket (50) has a loading section (124) and an extension (126), wherein the loading section is used to carry the luggage; the extension extends upward from the loading section (124), and the headlight (42) is located below the loading section (124).

[0058] This prevents the bracket from obstructing the headlight's light distribution.

[0059] In this embodiment of the invention, the instrument (46) is fixed to the instrument support (120) behind the loading part (124), the loading part (124) having a shape that expands as it approaches the instrument (46), and the bracket (50) also having a bend (132) that extends from the rear end of the loading part (124) toward the instrument support (120) and bends inward in the width direction of the straddle vehicle (10) from the side to the rear of the instrument (46).

[0060] This ensures sufficient space for instrument configuration while mounting the bracket and instrument onto the instrument support.

[0061] In this embodiment of the invention, the bracket (50) further has a straight section (130) that extends rearward in a straight line from the rear end of the loading section (124) and is connected to the bending section (132), on which a mounting support (52) for mounting a wind deflector (54) is mounted.

[0062] This allows for the installation of a windshield at the front of the motorcycle while ensuring space for the instrument panel.

[0063] In this invention, the instrument support (120) is mounted on the upper beam (24) and is positioned in front of the upper beam (24) when viewed from above.

[0064] This further reduces the torque on the vehicle body when loading luggage onto the rack.

[0065] In this embodiment of the invention, the straddle-type vehicle (10) further includes a lower beam (26) pivotally supported on the head tube (22), and the plurality of mounting portions (144, 145) are a first mounting portion (144) and a second mounting portion (145), wherein the first mounting portion has a first fastening portion (136) for fastening the bracket (50) to the instrument support (120); and the second mounting portion has a second fastening portion (142) for fastening the bracket (50) to the lower beam (26).

[0066] Therefore, since the bracket is fastened to the upper and lower parts of the vehicle body, it can be firmly fixed to the vehicle body. In addition, since the bracket and the vehicle body are not connected and fixed together, it is not easy for the fasteners to loosen.

[0067] In this invention, the bracket (50) has an outer frame (128) of a rod-shaped member (122), and the mounting part (144) has a planar part (134) formed by making the rear end of the bracket (50) planar, the planar part (134) being in contact with the instrument support (120).

[0068] This allows for both improved mountability of the bracket relative to the instrument support and improved appearance of the mounting section.
