[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6655728 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when a frame structure in which a main frame branches to the left and right is adopted for the body frame of a saddle-ride type vehicle, the space available on the inside in the vehicle width direction is restricted by the side frames where the main frame branches to the left and right. However, when a linked brake structure is adopted, clearance is required to take into account the range of movement of the equalizer, which requires that the space be expanded in the vehicle width direction, which can result in an increase in the vehicle width. The present invention has been made in consideration of the above-mentioned circumstances, and aims to make it easier to arrange an equalizer by effectively utilizing the space available on the inner side of the vehicle width direction, thereby making it easier to prevent the vehicle width from increasing. [Means for solving the problem]

Offset to the inside of the vehicle width Place in position To provide a saddle-ride type vehicle having an offset portion. [Effects of the Invention]

[0006] According to the present invention, the space available on the inner side in the vehicle width direction can be effectively utilized to facilitate placement of the equalizer, making it easier to suppress an increase in the vehicle width. [Brief explanation of the drawings]

[0015] A pair of steps 28 are provided on the left and right below the pivot shaft 22 and are used as driver's steps on which the driver places his or her feet. A fuel tank 29 is provided in front of the seat 17 and above the power unit 12, and is supported by the front frame 19. The fuel tank 29 is an example of an "energy storage unit" according to the present invention. The energy storage unit may be a battery, a fuel cell, or the like. In other words, the saddle-ride type vehicle 10 to which the present invention is applicable is not limited to vehicles that use fuel such as gasoline as an energy source, but may also be an electric vehicle that includes a power unit 12 having an electric motor and drives the power unit 12 with electricity from an energy storage unit consisting of a battery 44 or a fuel cell.

[0016] The front frame 19 includes a main frame 41 that branches into left and right sections toward the rear. The main frame 41 includes a center frame portion 41a that extends rearward from the head pipe 18 along the center of the vehicle width, and branch frame portions 41b that branch into left and right sections from the rear of the center frame portion 41a and extend downward toward the rear. The rear frame 20 includes left and right first rear frames 20a extending rearward from the middle of the main frame 41, and left and right second rear frames 20b extending rearward and upward from left and right branch frame portions 41b. The first rear frames 20a and second rear frames 20b can also be referred to as seat rails that support the seat 17. The left and right branch frame portions 41b, the left and right first rear frames 20a, and the left and right second rear frames 20b constitute a pair of side frames branching out from the main frame 41 to the left and right.

[0017] Intake system components 43, including a fuel supply device and an air cleaner box, are disposed behind the cylinder section 24. At least a portion of the intake system components 43 are disposed within a space SP1 surrounded by the main frame 41 and the left and right first and second rear frames 20a, 20b. A battery 44, which is one of the electrical components, is also disposed within the space SP1. In this configuration, the battery 44 is housed on one side (right side) of the space SP1 in the vehicle width direction, and the intake system components 43 are housed on the other side (left side) of the space SP1 in the vehicle width direction. The space SP1 is covered from the outside in the vehicle width direction by, for example, a side cover, and is not visible from the outside in the vehicle width direction.

[0018] An exhaust pipe 25a is connected to the front of the cylinder section 24. The exhaust pipe 25a extends downward from the front of the cylinder section 24, and then extends rearward below the power unit 12. An exhaust muffler 25b is connected to the rear end of the exhaust pipe 25a. The exhaust muffler 25b is disposed on one of the left and right sides (the right side in this embodiment) of the swing arm 16 and the rear wheel 15. The exhaust pipe 25a and the exhaust muffler 25b form an exhaust device 25. The configuration, shape, etc. of the exhaust device 25 may be changed as appropriate. In addition, a kick pedal 23p is disposed on the right side of the crankcase 23 and above the step 28.

[0019] The saddle-ride type vehicle 10 is equipped with a front wheel brake 51 that brakes the front wheel 13 and a rear wheel brake 52 that brakes the rear wheel 15. The front wheel brake 51 is connected to a brake lever 21r via a front wheel brake cable 51a that functions as a first front wheel brake force transmission member. The brake lever 21r is provided on one of the left and right ends (the right end in this embodiment) of the handlebar 21, and functions as a front wheel brake operator that is operated by the hand of the occupant (driver). When the brake lever 21r is operated by the occupant, the front wheel brake 51 is actuated, and a braking force is applied to the front wheel 13.

[0020] A disc brake, which is a type of hydraulic brake, is used for the front wheel brake 51. When a hydraulic brake is used, a master cylinder is provided that generates hydraulic pressure in response to braking operation, and a hydraulic hose is used for the front wheel brake cable 51a. The front wheel brake 51 is not limited to a disc brake, and may be a brake device other than a disc brake, such as a drum brake.

[0021] The rear wheel brake 52 is connected to a brake pedal 53 via a brake rod 52a that functions as a rear wheel brake force transmission member. The brake pedal 53 is provided near one of the left and right (right) steps 28 and functions as a rear wheel brake operator that is operated by the rider's foot. When the rider operates the brake pedal 53, the rear wheel brake 52 is actuated, and a braking force is applied to the rear wheel 15. A drum brake, which is a type of mechanical brake, is used for the rear wheel brake 52. The rear wheel brake 52 is not limited to a drum brake and may be a brake device other than a drum brake. Also, the brake rod 52a may be replaced with a brake cable or the like that can be used as a rear wheel braking force transmission member.

[0022] The saddle-ride type vehicle 10 having this configuration is provided with an interlocking brake mechanism 61 that activates both the front wheel brake 51 and the rear wheel brake 52 by operating the brake pedal 53. The interlocking brake mechanism 61 can also be called an interlocking brake, an interlocking brake structure, or an interlocking brake device. Fig. 2 is a right side view showing the main parts of the interlocking brake mechanism 61. In Fig. 2, the brake pedal 53 in the non-operated state is shown by a solid line, and the brake pedal 53 in the operated state is shown by a two-dot chain line. Fig. 3 is a perspective view showing the main parts of the interlocking brake mechanism 61 from the upper right. Note that Fig. 3 shows a state in which the area corresponding to the brake pedal 53 has been cut away. 2 and 3, an equalizer 63 is connected to the rear of the brake pedal 53 via a connecting pin 62a extending along the vehicle width direction. The equalizer 63 has a first connecting plate 71 connected to the brake pedal 53 via the connecting pin 62a and a second connecting plate 72 connected to the first connecting plate 71. In this embodiment, the swing arm 16 widens outward toward the rear of the vehicle (see Figure 3), so at least a portion of the equalizer 63 is positioned substantially above the swing arm 16 (corresponding to a position where they overlap vertically when viewed from the front-to-rear direction of the vehicle body).

[0023] FIG. 4 is a rear view of the main part of the interlocking brake mechanism 61. As shown in FIG. As shown in Figures 3 and 4, the first connecting plate 71 is formed of a single plate-like member extending in the vertical direction. The first connecting plate 71 is rotatably connected to the brake pedal 53 via the connecting pin 62a. The first connecting plate 71 integrally includes a first plate portion 71a extending downward in one longitudinal direction relative to the connecting pin 62a, and a second plate portion 71b extending upward in the other longitudinal direction relative to the connecting pin 62a. The front end of the brake rod 52a is connected to the lower part of the first plate portion 71a. The rear end of the brake rod 52a is connected to the rear wheel brake 52.

[0024] An intermediate portion 71c between the first plate portion 71a and the second plate portion 71b is formed as an inclined plate that is inclined inward in the vehicle width direction toward the second plate portion 71b when viewed in the vehicle front-rear direction. The second plate portion 71b extends upward from the intermediate portion 71c and is offset inward in the vehicle width direction relative to the first plate portion 71a. The second plate portion 71b is parallel to the first plate portion 71a and extends vertically. This second plate portion 71b constitutes an offset portion of the first connecting plate 71 that is offset inward in the vehicle width direction. Note that the second plate portion 71b does not have to be parallel to the first plate portion 71a and may have an appropriate shape.

[0025] 3, the lower part of the second connecting plate 72 is rotatably connected to the upper part of the second plate portion 71b via a connecting pin 62b that extends along the vehicle width direction. One end of an interlocking brake cable 51b that functions as a second front wheel brake force transmission member is connected to the upper part of the second connecting plate 72. The other end of the interlocking brake cable 51b is connected to the front wheel brake 51, and more specifically, to a master cylinder that generates hydraulic pressure for the front wheel brake 51.

[0026] 3, a rear end of a connecting rod 65, which corresponds to one longitudinal end, is connected to the vertical middle portion of the second connecting plate 72 via a connecting pin 62c extending along the vehicle width direction. A front end of the connecting rod 65, which corresponds to the other longitudinal end, is rotatably connected to a cross pipe 46 that forms part of the body frame 11 via a stay 47. The cross pipe 46 is a frame member that bridges the left and right branch frame portions 41b, and the stay 47 is a rigid member made of metal or the like that extends rearward from the cross pipe 46.

[0027] The connecting rod 65 is one of the members for setting the swing characteristics of the first connecting plate 71 and the second connecting plate 72. Therefore, the connecting rod 65 may have any appropriate shape and structure that can obtain the desired swing characteristics. The first connecting plate 71, the second connecting plate 72, and the connecting rod 65 are made from a single rigid plate member such as metal. For example, the plates 71, 72 and the connecting rod 65 may be made by bending a flat plate member or by molding, with holes drilled for attaching the connecting pins 62a to 62c. However, the structure, shape, and manufacturing method of the plates 71, 72 and the connecting rod 65 may be changed as appropriate. As shown in FIG. 4, a main harness 48 is routed below the intake system components 43 and on the inner side of the second connecting plate 72 in the vehicle width direction.

[0028] The interlocking brake mechanism 61 includes a biasing member 66 that biases the equalizer 63 in a direction that does not activate the front wheel brake 51 and the rear wheel brake 52. As shown in FIG. 3 , the biasing member 66 is attached to the upper part of the second connecting plate 72, and biases the second connecting plate 72 in a clockwise direction when viewed from the right side of the vehicle body. The biasing member 66 in this embodiment is a coil spring, but a biasing member other than a coil spring may also be used.

[0029] When the brake pedal 53 is operated, the first connecting plate 71 of the equalizer 63 rotates counterclockwise about the connecting pin 62a as viewed from the right side of the vehicle body, actuating the rear wheel brake 52 via the brake rod 52a. Furthermore, the second connecting plate 72 of the equalizer 63 rotates counterclockwise about the connecting pin 62c as viewed from the right side of the vehicle body, actuating the front wheel brake 51 via the interlocking brake cable 51b. The ratio between the braking force of the front wheel brake 51 and the braking force of the rear wheel brake 52 is set to an appropriate ratio by an equalizer 63. The shape and structure of each part of the interlocking brake mechanism 61 and the positions of each of the connecting pins 62a to 62c may be changed as appropriate. The interlocking brake cable 51b in this embodiment is a wire type having an inner wire inside an outer cable, but any member usable as a front wheel brake force transmission member may be used.

[0030] 2, at least a portion of the equalizer 63 is disposed in a space SP1 surrounded by the main frame 41, the left and right first rear frames 20a, and the left and right second rear frames 20b. Furthermore, at least a portion of the second connecting plate 72 of the equalizer 63 overlaps with the second rear frame 20b in a side view of the vehicle body. In this configuration, as shown in FIG. 4, the second plate portion 71b of the first connecting plate 71, which is offset inward in the vehicle width direction, is positioned more inward in the vehicle width direction than the second rear frame 20b on the right side, and the first plate portion 71a is positioned lower than the second rear frame 20b.

[0031] As described above, the space SP1 accommodates the intake system components 43 and the battery 44, which are large components among the vehicle body mounted components, and therefore the space available in the space SP1 in the vehicle width direction is restricted, for example, the space available on the inside of the right second rear frame 20b in the vehicle width direction is restricted. In this way, even when the space available on the inside of the right-side second rear frame 20b in the vehicle width direction is limited, the second plate portion 71b can be positioned with sufficient clearance by positioning the second plate portion 71b offset inward in the vehicle width direction. This makes it easier to position the first connecting plate 71 having the second plate portion 71b and the second connecting plate 72 connected to the first connecting plate 71 with an appropriate clearance without expanding the space SP1 in the vehicle width direction. Therefore, it becomes easier to position the equalizer 63 with an appropriate clearance without expanding the space SP1 in the vehicle width direction, and it becomes easier to suppress an increase in vehicle width even when the interlocking brake mechanism 61 including the equalizer 63 is positioned.

[0032] 2, the equalizer 63 is disposed in the space SP1, which is located behind the branch frame portion 41b of the main frame 41, below the battery 44, and on the inner side of the second rear frame 20b in the vehicle width direction, in a side view of the vehicle body. Therefore, the equalizer 63 can be disposed by effectively utilizing the space below the battery 44. This also makes it easier to dispose the equalizer 63 with an appropriate clearance without expanding the space SP1 in the vehicle width direction, making it easier to suppress an increase in the vehicle width.

[0033] 4, the second plate portion 71b is located below and inside the right-side second rear frame 20b in the vehicle width direction, and the second connecting plate 72 is connected to the inside of this second plate portion 71b in the vehicle width direction. This allows the second connecting plate 72, which is located inside the right-side second rear frame 20b in the vehicle width direction and overlaps the second rear frame 20b in the vehicle width direction, to be positioned using the space inside the right-side second rear frame 20b in the vehicle width direction. 4, the first plate portion 71a of the first connecting plate 71, which is located below the second plate portion 71b and on the outer side in the vehicle width direction, is positioned so as to overlap with the swing arm 16 in the vehicle width direction. This allows the first plate portion 71a to be positioned using the space available on the outer side in the vehicle width direction of the swing arm 16. This makes it easier to appropriately position the equalizer 63 by effectively utilizing a narrow space.

[0034] 4, the second connecting plate 72 is disposed in a position that overlaps the swing arm 16 in the vertical direction when viewed in the front-to-rear direction of the vehicle body. This allows the second connecting plate 72 to be disposed in the space that is free in the vertical direction of the swing arm 16. This also makes it easier to appropriately dispose the equalizer 63 by effectively utilizing a narrow space.

[0035] As described above, the saddle-ride type vehicle 10 of this embodiment is provided with the interlocking brake mechanism 61 in which one end of the interlocking brake cable 51b is connected to the brake pedal 53 via the equalizer 63, and the other end of the interlocking brake cable 51b is connected to the front wheel brake 51, so that both the rear wheel brake 52 and the front wheel brake 51 are actuated by operation of the brake pedal 53. The equalizer 63 of the interlocking brake mechanism 61 has a second plate portion 71b that forms an offset portion offset inward in the vehicle width direction.

[0036] According to this configuration, the second plate portion 71b offset inward in the vehicle width direction makes it possible to effectively utilize the space on the inner side in the vehicle width direction, making it easier to arrange the equalizer 63 with an appropriate clearance. This makes it easier to suppress an increase in vehicle width that would otherwise be caused by the arrangement of the interlocking brake mechanism 61 including the equalizer 63.

[0037] The body frame 11 also has left and right branch frame portions 41b constituting a pair of side frames branching out in the left-right direction from the main frame 41, and left and right first rear frames 20a and second rear frames 20b. The equalizer 63 has a first connecting plate 71 connected to the brake pedal 53 and having a second plate portion 71b, and a second connecting plate 72 connected to the first connecting plate 71 and to which one end of the interlocking brake cable 51b is connected, and at least a portion of the second plate portion 71b overlaps with the second rear frame 20b constituting a part of the side frames in a side view of the vehicle body.

[0038] With this configuration, even when the space in the vehicle width direction is narrowed by a pair of side frames branching out laterally from the main frame 41, the first connecting plate 71 having the second plate portion 71b can be positioned using that narrow space. Furthermore, by connecting the second connecting plate 72 to the second plate portion 71b, it can also be positioned using the space on the inner side in the vehicle width direction. As a result, the first connecting plate 71 and the second connecting plate 72 can be positioned using the space available on the inner side in the vehicle width direction, and the equalizer 63 can be easily positioned appropriately by effectively using the space available on the inner side in the vehicle width direction.

[0039] The vehicle also has a swing arm 16 that supports the rear wheel 15, and at least a portion of the second connecting plate 72 overlaps with the swing arm 16 in the vertical direction when viewed in the front-to-rear direction of the vehicle body. With this configuration, the second connecting plate 72 can be arranged using the space available above and below the swing arm 16. This makes it easier to appropriately arrange the equalizer 63 by effectively utilizing the space available above and below the swing arm 16.

[0040] Furthermore, the first connecting plate 71, which is a component of the equalizer 63 and has the second plate portion 71b that constitutes the offset portion, is formed from a single plate-like member, which makes it possible to make the first connecting plate 71 more compact in the vehicle width direction and easier to manufacture. This is advantageous for reducing the number of components of the equalizer 63 and simplifying the structure of the equalizer 63. The shape and configuration of each part of the equalizer 63, such as the first connecting plate 71 and the second connecting plate 72, may be changed as appropriate. The first connecting plate 71 is an example of a "first connecting member" in the present invention, and the second connecting plate 72 is an example of a "second connecting member" in the present invention.

[0041] [Other embodiments] The above-described embodiment merely shows one aspect of the present invention, and any modifications and applications are possible without departing from the spirit of the present invention.

[0042] In the above embodiment, the equalizer 63 has been exemplified as having two plate-shaped members consisting of a first connecting plate 71 and a second connecting plate 72, but it may also be configured as having a single connecting plate in which the first connecting plate 71 and the second connecting plate 72 are integrated. 5 and 6 are views showing essential parts of an interlocking brake mechanism 61 according to another embodiment. More specifically, FIG. 5 shows the essential parts of the interlocking brake mechanism 61 according to another embodiment from the rear, and FIG. 6 shows the essential parts from the right side. The interlocking brake mechanism 61 according to another embodiment differs in that the equalizer 63 has a single connecting plate. The single connecting plate serves as both the first connecting plate 71 and the second connecting plate 72 of the above embodiment, but has a similar configuration to the first connecting plate 71, and therefore, hereinafter, the single connecting plate will be referred to as the "first connecting plate 71." In FIG. 5, components similar to those of the above embodiment are designated by the same reference numerals, and redundant description will be omitted.

[0043] 5, the first connecting plate 71 is formed of a single plate-like member extending in the vertical direction and is rotatably supported on the brake pedal 53 via a connecting pin 62a. The second plate portion 71b of the first connecting plate 71 extends upward from the upper end of the middle portion 71c and forms an offset portion that is offset inward in the vehicle width direction relative to the first plate portion 71a. The second plate portion 71b forms part of the second connecting plate 72 in the above embodiment; in other words, it extends upward further than the first connecting plate 71 in the above embodiment, and one end of the interlocking brake cable 51b and one end of the biasing member 66 are connected to the second plate portion 71b. In other embodiments, the swing arm 16 also widens outward toward the rear of the vehicle, so that at least a portion of the equalizer 63 (second plate portion 71b) is positioned substantially above the swing arm 16 (corresponding to a position where they overlap vertically when viewed in the fore-and-aft direction of the vehicle body).

[0044] As shown in FIG. 6 , the interlocking brake cable 51b is pulled out rearward of the equalizer 63. The equalizer 63 is biased by a biasing member 66 in a counterclockwise direction as viewed from the right side of the vehicle body. In another embodiment, when the brake pedal 53 is operated, the first connecting plate 71 of the equalizer 63 rotates about the connecting pin 62a against the biasing force of the biasing member 66, thereby actuating the rear wheel brake 52 via the brake rod 52a and actuating the front wheel brake 51 via the interlocking brake cable 51b. As a result, operation of the brake pedal 53 actuates both the rear wheel brake 52 and the front wheel brake 51, and braking forces are applied to the rear wheel 15 and the front wheel 13.

[0045] 5 and 6, at least a portion of the second plate portion 71b constituting the offset portion overlaps, in a side view of the vehicle body, with the second rear frame 20b constituting part of a pair of side frames branching off in the left-right direction from the main frame 41. As a result, even if the space in the vehicle width direction is narrowed by the pair of side frames branching off in the left-right direction from the main frame 41, the first connecting plate 71 having the second plate portion 71b can be disposed in that narrow space. This makes it easier to appropriately dispose the equalizer 63 by effectively utilizing the space available on the inner side in the vehicle width direction, and makes it easier to suppress an increase in vehicle width that would be otherwise caused by disposing the interlocking brake mechanism 61 including the equalizer 63.

[0046] 5, the second plate portion 71b of the first connecting plate 71 overlaps the swing arm 16 in the vertical direction when viewed in the vehicle front-rear direction. With this configuration, the first connecting plate 71 can be positioned using the space available in the vertical direction of the swing arm 16, making it easier to appropriately position the equalizer 63 by effectively utilizing the space available on the inner side in the vehicle width direction.
