Summary of the Invention

Problem to be Solved by the Invention

[0004] In the technology described in Patent Document 1, the CBS mechanism has a configuration that has vertical height and front-to-back length above the pedal end, which tends to result in a relatively large installation space. Furthermore, in the CBS mechanism described in Patent Document 1, the link plate is supported via a support plate, resulting in a complex configuration for the CBS link, and a simpler structure that takes into account the input of the linked brake is desired. The present invention has been made in view of the above circumstances, and aims to suppress the complexity of the configuration in a CBS mechanism in which an equalizer to which a rear wheel brake operating member is connected and a link plate to which an interlocking brake operating member is connected are provided as separate components. [Means for solving the problem]

[0005] A saddle-type vehicle comprises a main frame extending rearward from a head pipe, a pivot frame extending downward from the main frame, a brake pedal pivotably supported on the pivot frame via a pedal pivot shaft, and a CBS mechanism that applies braking force to the front and rear wheels in response to the operation of the brake pedal, wherein the CBS mechanism comprises an equalizer to which a rear wheel brake operating member for operating the rear wheel brake is connected, and a link plate to which an interlocking brake operating member for operating the front wheel brake is connected, the brake pedal comprises a pedal end extending from the pedal pivot shaft, and the CBS mechanism comprises the equalizer pivotably supported on the pedal end, the link plate pivotably supported on the vehicle body, and a link member connecting the equalizer and the link plate. [Effects of the Invention]

[0006] In a CBS mechanism in which an equalizer to which a rear wheel brake operating member is connected and a link plate to which an interlocking brake operating member is connected are provided as separate components, it is possible to suppress the complexity of the configuration.

[Modes for carrying out the invention]

[0008] Embodiments of the present invention will be described below with reference to the drawings. In the description, directions such as front, back, left, right, and up and down refer to directions relative to the vehicle body unless otherwise specified. In each figure, the symbol FR indicates the front of the vehicle body, the symbol UP indicates the top of the vehicle body, and the symbol LH indicates the left side of the vehicle body.

[0009] [Embodiment] Figure 1 is a side view of a saddle-type vehicle 10 according to an embodiment of the present invention. The saddle-type vehicle 10 is a vehicle that comprises a body frame 11, a power unit 12 supported by the body frame 11, a front fork 14 that supports the front wheel 13 in a steerable manner, a swing arm 16 that supports the rear wheel 15, and a seat 17 for the rider. A straddle-type vehicle 10 is a vehicle in which an occupant sits astride a seat 17. The seat 17 is provided above a rear portion of a vehicle body frame 11.

[0010] The vehicle body frame 11 includes a head pipe 18 provided at a front end portion of the vehicle body frame 11, a front frame 19 positioned behind the head pipe 18, and a rear frame 20 positioned behind the front frame 19. A front end portion of the front frame 19 is connected to the head pipe 18. The seat 17 is supported by the rear frame 20.

[0011] A front fork 14 is supported by the head pipe 11 so as to be steerable left and right. A front wheel 13 is supported by an axle 13a provided at a lower end portion of the front fork 14. A steering handlebar 21 gripped by an occupant is attached to an upper end portion of the front fork 14.

[0012] A swing arm 16 is supported by a pivot shaft 22 supported by the vehicle body frame 11. The pivot shaft 22 is a shaft that extends horizontally in a vehicle width direction. The pivot shaft 22 is inserted through a front end portion of the swing arm 16. The swing arm 16 swings up and down about the pivot shaft 22. A rear wheel 15 is supported by an axle 15a provided at a rear end portion of the swing arm 16.

[0013] A power unit 12 is disposed between the front wheel 13 and the rear wheel 15, and is supported by the vehicle body frame 11. The power unit 12 is an internal combustion engine. The power unit 12 includes a crankcase 23 and a cylinder portion 24 that houses a reciprocating piston. An exhaust device 25 is connected to an exhaust port of the cylinder portion 24. Output of the power unit 12 is transmitted to the rear wheel 15 by a driving force transmission member that connects the power unit 12 and the rear wheel 15.

[0014] Further, the straddle-type vehicle 10 includes a front fender 26 that covers the front wheel 13 from above, a rear fender 27 that covers the rear wheel 15 from above, steps 28 on which an occupant places their feet, and a fuel tank 29 that stores fuel used by the power unit 12. The front fender 26 is attached to the front fork 14. The rear fender 27 and the steps 28 are provided below the seat 17. The fuel tank 29 is supported by the vehicle body frame 11.

[0015] In the present embodiment, the front frame 19 includes a main frame 31 extending rearward and downward from the head pipe 18, and a pivot frame 32 extending downward from the rear end of the main frame 31. A pivot shaft 22 extending in the vehicle width direction is supported at a midway position of the pivot frame 32 in the vertical direction. The swing arm 16 is swingably supported by the pivot shaft 22. The power unit 12 is supported by the main frame 31 and the pivot frame 32.

[0016] The rear frame 20 includes a pair of left and right seat frames 33 extending rearward from a rear portion of the main frame 31, and a pair of left and right rear sub-frames 34 extending rearward from the rear end of the main frame 31 and connected to a midway portion of the seat frames 33 in the front-rear direction.

[0017] The vehicle body frame 11 is covered by a vehicle body cover 40. The vehicle body cover 40 includes a front cover 41 that covers the front of the head pipe 18, a pair of left and right leg shields 42 disposed behind the front cover 41, a center cover 43 disposed between the leg shields 42 and covering the main frame 31 from above, a body cover 44 that covers the main frame 31, the seat frames 33, and the rear sub-frames 34 from the outer sides in the left-right direction, and a rear cover 45 that covers the rear ends of the seat frames 33 from the left and right sides.

[0018] The seat 17 of the present embodiment includes a front rider seat portion 17a and a rear pillion seat portion 17b located behind the rider seat portion 17a. A step 28 is positioned below the rider seat portion 17a. The step 28 is provided at both ends of a step rod 28a that extends in the vehicle width direction. The step rod 28a is fixed to the lower surface of the crankcase 23.

[0019] A pillion step 51 is provided on the lower front side of the pillion seat portion 17b. The pillion step 51 is supported by the rear subframe 34 via a pillion step bracket 52. The pillion step 51 is supported by the pillion step bracket 52 so as to be able to fold down.

[0020] As shown in Figure 1, the front wheel 13 is provided with a front wheel brake 61 that brakes the front wheel 13. In this embodiment, the front wheel brake 61 is a hydraulic disc brake. The front wheel brake 61 comprises a brake disc 61a integrally mounted on the front wheel 13 and a brake caliper 61b attached to the lower end of the front fork 14 that clamps the brake disc 61a to provide braking. A brake hose 62 is connected to the brake caliper 61b. The brake hose 62 extends upward and is connected to a master cylinder unit (master cylinder) 80 fixed to the right side of the handlebars 21. The master cylinder unit 80 is operable with the front wheel brake lever 63.

[0021] When the front brake lever 63 is operated by the occupant, the piston of the master cylinder unit 80 is pressed, and hydraulic pressure is applied to the brake caliper 61b via the brake hose 62. As a result, the brake caliper 61b clamps the brake disc 61a, and braking force is applied to the front wheel 13.

[0022] The rear wheel 15 is equipped with a rear wheel brake 64 for braking the rear wheel 15. In this embodiment, the rear wheel brake 64 is a drum brake. The rear wheel brake 64 includes a brake panel 64a, a brake arm 64b, brake shoes (not shown), etc. A torque rod 65 extending in the front-rear direction is connected to the lower part of the rear wheel brake 64. The torque rod 65 is supported at the front end of the swing arm 16.

[0023] A rear brake rod 66 extending forward is connected to the brake arm 64b of the rear brake 64. The rear brake rod (rear brake operating member) 66 is configured to be able to be linked to a brake pedal (rear brake operator) 53 located around the right-side step 28.

[0024] The brake pedal 53 is pivotably supported on the pivot frame 32. The brake pedal 53 is pivotably supported between a normal position when the brake is not applied (see solid line in Figure 1) and an applied position when the front end is pushed downward (see dashed line in Figure 1). When the brake pedal 53 is operated by the occupant, the rear brake rod 66 is pulled forward and the brake arm 64b rotates. This activates the rear wheel brake 64 and applies braking force to the rear wheel 15.

[0025] In this embodiment, the saddle-type vehicle 10 is provided with a CBS mechanism 100 around the pivot frame 32, which activates both the front wheel brake 61 and the rear wheel brake 64 by operating the brake pedal 53.

[0026] A linked brake cable (linked brake operating member) 67 is connected to the CBS mechanism 100. The linked brake cable 67 extends upward from the CBS mechanism 100, is routed upward along the pivot frame 32, and is routed forward along the main frame 31. The linked brake cable 67 is then routed upward along the head pipe 18 and is routed toward the master cylinder unit 80.

[0027] Figure 2 shows the area around the front brake lever 63 viewed from the front. Figure 3 shows the area around the front brake lever 63 viewed from above. Figure 4 shows the area around the front brake lever 63 viewed from below. Note that the directional arrows in Figures 3 to 8 are added for explanatory purposes and may not strictly coincide with the direction of the saddle-type vehicle 10. A grip portion 38, which the occupant holds with their right hand, is provided at the right end of the steering wheel 21. A master cylinder unit 80, which has a reservoir 81 integrated into it, is mounted inward from the grip portion 38 in the vehicle width direction.

[0028] The master cylinder unit 80 is integrally provided with a semi-circular mounting portion 80a (see Figure 4) that fits onto the underside of the handle 21. Opposite the mounting portion 80a, a mirror support member 83 is positioned on the upper side of the handle 21. The mirror support member 83 is integrally provided with a semi-circular mounting portion 83a (see Figure 3) that fits onto the upper side of the handle 21. The mounting portion 83a of the mirror support member 83 is fastened to the mounting portion 80a of the master cylinder unit 80 with a pair of bolts 89 (see Figure 3), sandwiching the handle 21 (not shown in Figures 2 to 4). In this way, the master cylinder unit 80 and the mirror support member 83 are attached to the handle 21. The mirror support portion 83b of the mirror support member 83 supports the right mirror 39 (see Figure 1).

[0029] Figure 5 is a perspective view of the area around the front brake lever 63, seen from the upper right. Inside the master cylinder unit 80, a piston rod 82 that supports a piston (not shown) is slidably supported. The piston rod 82 is slidably supported in the master cylinder unit 80 in the vehicle width direction. A hose connection portion 80b (see Figure 2) is provided at the inner end of the master cylinder unit 80 in the vehicle width direction. A brake hose 62 is connected to the hose connection portion 80b. As a result, when the piston rod 82 is pushed, hydraulic pressure is applied to the brake caliper 61b via the brake hose 62.

[0030] A stop switch 86 (see Figures 2 and 4) is mounted on the lower part of the master cylinder unit 80. The stop switch 86 has a detection element (not shown) that is configured to move forward and backward. The stop switch 86 detects whether or not the detection element has been pressed and inputs a detection signal to an ECU (Electronic Control Unit) (not shown) via a harness.

[0031] As shown in Figure 2, plate-shaped brackets 80c and 80d are integrally provided on the front of the master cylinder unit 80, spaced apart in the vertical direction. A support shaft 84 is supported by the brackets 80c and 80d, extending between the upper bracket 80c and the lower bracket 80d. The support shaft 84 has a head 84a and a screw shaft portion 84c at its lower end.

[0032] The support shaft 84 passes through the brackets 80c and 80d, and a nut 85 is fastened to the threaded shaft portion 84c. This fixes the support shaft 84 to the brackets 80c and 80d. In this fixed state, the head portion 84a of the support shaft 84 is spaced upward from the upper surface of the upper bracket 80c. A return spring (not shown) is installed between the head portion 84a and the upper bracket 80c to bias the front wheel brake lever 63 to a predetermined position.

[0033] Between the upper bracket 80c and the lower bracket 80d, the pivot shaft 84 supports a front wheel brake lever 63 and a knocker 87 that can be linked to the front wheel brake lever 63, so as to be able to swing. The knocker 87 is supported so as to be able to swing relative to the front wheel brake lever 63.

[0034] The knocker 87 has a swinging plate portion 87a that is swingably supported on a support shaft 84. A connecting portion 87b is formed at the front end of the swinging plate portion 87a, extending downward along the support shaft 84. An arm portion 87c is formed at the lower end of the connecting portion 87b, extending toward the support shaft 84 along the swinging plate portion 87a.

[0035] The oscillating plate portion 87a is provided with a piston pressing portion 87d (see Figure 5) that presses against the rear end of the piston rod 82. The piston pressing portion 87d presses against the piston rod 82 when the oscillating plate portion 87a oscillates around the pivot shaft 84. The oscillating plate portion 87a has a detection pressing portion 87e (see Figures 2 and 4) that extends downward on the opposite side of the connecting portion 87b, with the support shaft 84 in between. The detection pressing portion 87e can be used to press the detector of the stop switch 86.

[0036] In other words, when the knocker 87 is not oscillating, the detection pressing unit 87e presses the detector of the stop switch 86. Then, when the knocker 87 oscillates and the detection pressing unit 87e oscillates in a direction away from the detector of the stop switch 86, the detector protrudes from the stop switch 86. This makes it possible for the stop switch 86 to detect both the state in which the knocker 87 is not oscillating and the front wheel brake 61 is not activated, and the state in which the knocker 87 is oscillating and the front wheel brake 61 is activated.

[0037] A knocker pressing portion 63a (see Figures 2 and 4) is provided at the base of the front brake lever 63, which is the pivot point side, to press against the knocker 87. When the front brake lever 63 is operated, the knocker pressing portion 63a presses against the knocker 87, causing the knocker 87 to pivot as a whole. In other words, the front brake lever 63 presses against the piston rod 82 via the knocker 87.

[0038] The front brake lever 63 is biased by a return spring (not shown) in a direction away from the grip portion 38, that is, in a direction in which the knocker pressing portion 63a moves away from the knocker 87. The knocker 87 is able to follow the knocker pressing portion 63a of the front brake lever 63 due to the reaction force it receives from the piston rod 82 of the master cylinder unit 80.

[0039] Figure 6 is a rear view of the connection structure between the adjustment mechanism 90 of the interlocking brake cable 67 and the knocker 87. The arm portion 87c of the knocker 87 is connected to the interlocking brake cable 67 via the adjustment mechanism 90.

[0040] As shown in Figure 2, the adjustment mechanism 90 includes a cable holder 91 through which the inner cable 67b of the interlocking brake cable 67 passes, a cable joint (adjustment part) 92 through which the inner cable 67b is connected via a locking piece 67c, and a regulating spring 93 provided between the cable holder 91 and the cable joint 92.

[0041] The cable holder 91 is formed in a cylindrical shape. The cable holder 91 is supported by the master cylinder unit 80. A reduced diameter section (not shown) is formed inside the cable holder 91. The end of the regulating spring 93 abuts against the reduced diameter section.

[0042] A screw cylinder 94 is slidably inserted into the cable holder 91 in the vehicle width direction, inward from the reduced diameter portion. The screw cylinder 94 is fixed to the outer cable 67a of the interlocking brake cable 67. A screw groove is provided on the outer surface of the screw cylinder 94. An adjustment nut 95 and a lock nut 96 are screwed onto the screw cylinder 94. The length of the interlocking brake cable 67 is adjusted by changing the forward and backward positions of the adjustment nut 95 and the lock nut 96, so that the adjustment nut 95 comes into contact with the cable holder 91.

[0043] As shown in Figure 6, the cable joint 92 is a roughly U-shaped bent plate when viewed from the front. More specifically, the cable joint 92 comprises a base portion 92a extending in the vertical direction and a pair of extension portions 92b and 92c extending outward in the vehicle width direction from both the upper and lower ends of the base portion 92a. The extension portions 92b and 92c in this embodiment are identical in shape. On the tip side of the pair of extension portions 92b and 92c, that is, on the side opposite to the base portion 92a in the longitudinal direction of the extension portions 92b and 92c, a tapered portion 92d is formed that tapers towards the tip.

[0044] A C-shaped hole 92e (see Figure 2) is formed in the base portion 92a. The C-shaped hole 92e is a hole in which a portion in the circumferential direction is open in the radial direction. An inner cable 67b is inserted through the C-shaped hole 92e. The inner cable 67b is connected to the base portion 92a via a locking ring 67c.

[0045] An elongated hole 92f (see Figures 4 and 5) extending along the longitudinal direction is formed in the upper extension 92b and the lower extension 92c. An engagement pin 88 is inserted through the elongated hole 92f. The engagement pin 88 has a head portion 88a with a diameter larger than the width W2 (see Figure 7) of the elongated hole 92f, and a shaft portion 88b with a diameter smaller than the width W2 (see Figure 7) of the elongated hole 92f. The engagement pin 88 is supported by the arm portion 87c of the knocker 87. As a result, the interlocking brake cable 67 is connected to the arm portion 87c of the knocker 87 via the cable joint 92.

[0046] The regulating spring 93 is sandwiched between the reduced diameter portion of the cable holder 91 and the base portion 92a of the cable joint 92. The regulating spring 93 maintains a predetermined distance between the cable joint 92 and the cable holder 91 when the front wheel brake lever 63 and brake pedal 53 are not operated.

[0047] Figure 7 is a view of the cable joint 92 in the axial direction from which the engagement pin 88 extends. In other words, Figure 7 is a view of the engagement pin 88 in the axial direction. In the cable joint 92 of this embodiment, the extensions 92b and 92c have a width W1. The width W1 is the length in the direction perpendicular to the longitudinal direction of the extensions 92b and 92c.

[0048] The elongated hole 92f is formed by a pair of straight sections (straight inner edges) 92f1 extending along the longitudinal direction and a pair of semi-circular sections (curved inner edges) 92f2 extending from both ends of the pair of straight sections 92f1. The width W2 of the elongated hole 92f is determined by the distance between the straight sections 92f1. In the extensions 92b and 92c, the width W4 on both sides of the elongated hole 92f is half the value obtained by subtracting the width W2 of the elongated hole 92f from the width W1 of the extensions 92b and 92c. In other words, the width W4 is the distance from the straight section 92f1 of the elongated hole 92f to the ends of the extensions 92b and 92c. Having a width W4 ensures the rigidity of the extensions 92b and 92c in which the elongated hole 92f is formed.

[0049] The tapered portion 92d is formed closer to the tip 92d1 than the straight portion 92f1. The tapered portion 92d is symmetrical. The tapered portion 92d has a rounded triangular shape.

[0050] Here, position P11 is defined as a position that is separated from the end P1 on the tip 92d1 side of the elongated hole 92f by a distance equal to the width W4 of one side of the elongated hole 92f toward the tip 92d1 side. In this case, the tapered portion 92d has a tapered shape that protrudes in the longitudinal direction toward the tip 92d1 side from position P11. In other words, the tapered portion 92d has a tapered shape that is further away from the elongated hole 92f than the width W4. This ensures that sufficient area is secured even as a tapered shape, so that the end strength of the cable joint 92 is ensured while the tapered portion 92d is made visible.

[0051] As shown in Figures 5 to 7, a stepped portion 98 is formed at the end of the arm portion 87c of the knocker 87, corresponding to the position of the tapered portion 92d. The stepped portion 98 is formed on the upper surface of the arm portion 87c. That is, the stepped portion 98 has an inner end portion 98a extending downward from the upper surface of the arm portion 87c, a stepped surface portion 98b extending outward in the vehicle width direction from the lower end of the inner end portion 98a, and an outer end portion 98c extending downward from the outer end of the stepped surface portion 98b in the vehicle width direction. The inner end portion 98a and the outer end portion 98c extend so as to intersect with the direction of movement of the cable joint. In this embodiment, the inner end portion 98a and the outer end portion 98c extend in the front-rear direction. The inner end portion 98a and the outer end portion 98c form a predetermined distance δ when viewed in the axial direction of the engagement pin 88. The predetermined distance δ is about 1 mm.

[0052] The inner end 98a and the outer end 98c are formed in such a position that, when viewed axially from the engagement pin 88, the tip 92d1 of the cable joint 92 overlaps the stepped portion 98, the length of the interlocking brake cable 67 is as designed. Therefore, the spacing δ is the adjustment range of the cable joint 92. In other words, the spacing δ is an indicator that the tip 92d1 of the tapered portion 92d of the cable joint 92 should be within the range of spacing δ.

[0053] Figure 8 shows the state in which the cable joint 92 has moved relative to that shown in Figure 7. In Figure 8, the case where the tip 92d1 overlaps with the inner end 98a is shown by a dashed line. Also in Figure 8, the case where the tip 92d1 overlaps with the outer end 98c is shown by a double dashed line. In an axial view of the engagement pin 88, if the tip 92d1 of the cable joint 92 overlaps with the stepped portion 98, a gap is created between the shaft portion 88b of the engagement pin 88 and the semi-circular portion 92f2 at the tip of the elongated hole 92f. That is, whether the tip 92d1 overlaps with the inner end portion 98a (single dashed line) or the tip 92d1 overlaps with the outer end portion 98c (double dashed line), there is play A between the shaft portion 88b of the engagement pin 88 and the semi-circular portion 92f2 at the tip of the elongated hole 92f. This makes it possible to adjust the position of the engagement pin 88, which is fixed to the knocker 87, relative to the cable joint 92.

[0054] In an axial view of the engagement pin 88, when the tip 92d1 of the cable joint 92 overlaps with the outer end 98c of the stepped portion 98 (see the dashed line in Figure 8), the maximum overlap W0 in the width direction between the tapered portion 92d of the cable joint 92 and the stepped portion 98 is less than or equal to half the width W3 of the stepped portion 98. Therefore, in an axial view of the engagement pin 88, when the tip 92d1 of the cable joint 92 and the stepped portion 98 overlap, in other words, when the tip 92d1 of the cable joint 92 is included in the gap δ, the overlap W0 in the width direction between the tapered portion 92d of the cable joint 92 and the stepped portion 98 is less than or equal to half the width W3 of the stepped portion 98.

[0055] With this adjustment mechanism 90, when the front brake lever 63 is operated, the knocker pressing portion 63a of the front brake lever 63 presses against the knocker 87. As a result, the knocker 87 swings, pressing against the piston rod 82 of the master cylinder unit 80, and the front brake 61 is activated. At this time, since the engagement pin 88 of the arm portion 87c of the knocker 87 is movable along the elongated hole 92f, the knocker 87 can swing without being affected by the cable joint 92.

[0056] Furthermore, if the front brake lever 63 is not operated and only the brake pedal 53 is operated, the CBS mechanism 100 is activated. As a result, the inner cable 67b of the linked brake cable 67 is pulled, and a braking force is applied to the cable joint 92. At this time, the cable joint 92 will not move due to the regulating spring 93, and the knocker 87 will not swing, until the braking force exceeds the set load of the regulating spring 93.

[0057] In other words, in the initial stages of braking with the CBS mechanism 100, until a force corresponding to the set load of the regulating spring 93 acts on the interlocking brake cable 67, no pressing force from the knocker 87 acts on the master cylinder unit 80, and the front wheel brake 61 does not operate.

[0058] Then, when a force greater than the set load of the regulating spring 93 is applied from the linked brake cable 67, the cable joint 92 is pulled, and the knocker 87 swings around the pivot shaft 84 via the engagement pin 88. As a result, the pressing force from the knocker 87 acts on the piston rod 82 of the master cylinder unit 80, and the front wheel brake 61 is activated.

[0059] Thus, the operating behavior of the front brake 61 can be changed by the braking force applied by the linked brake cable 67. In this embodiment, the length of the linked brake cable 67 is adjusted by changing the forward and backward positions of the adjustment nut 95 and the lock nut 96 by bringing the adjustment nut 95 into contact with the cable holder 91. That is, by adjusting the position of the outer cable 67a relative to the cable holder 91, the path length of the inner cable 67b is adjusted, and the braking force of the inner cable 67b is adjusted.

[0060] At this time, the tip 92d1 of the cable joint 92 is adjusted to be located within the spacing δ of the stepped portion 98. In this embodiment, the tip 92d1 and the stepped portion 98 are easily visible in a plan view (see Figures 7 and 8), a side view (see Figure 5), and a rear view (see Figure 6), and adjustment is also possible in a predetermined axial direction view. Furthermore, in this embodiment, since the upper and lower extensions 92b and 92c have the same shape, it is possible to confirm in a bottom view (see Figure 4) that the adjustment range is exceeded, that is, the tip 92d1 of the cable joint 92 exceeds the outer end portion 98c.

[0061] Here, since the cable joint 92 has a tapered portion 92d on the tip 92d1 side, the shape of the stepped portion 98 is more easily exposed upwards compared to the case where the tip 92d1 side is rectangular. Therefore, the amount of upward exposure of the stepped portion 98 is easily secured, improving the visibility of the stepped portion 98, and making it easier to see the positional relationship between the stepped portion 98 and the tip 92d1. Therefore, when aligning the cable joint 92 of the adjustment mechanism 90 with the end of the knocker 87, visibility is improved, and the operation of adjusting the length of the interlocking brake cable 67 is made easier. Furthermore, visibility can be further improved by coloring the tapered portion 92d of the cable joint 92 or the stepped portion 98 of the knocker 87. Since the tapered portion 92d of the cable joint 92 has a tapered shape, it is possible to determine whether or not there is overlap even if it intersects the stepped portion 98 at an angle. Therefore, the cable joint 92 can also be used in vehicle types other than the saddle-type vehicle 10 of this embodiment.

[0062] Figure 9 is a right side view showing the peripheral area of ​​the CBS mechanism 100 and the cover member 70 that covers the CBS mechanism 100. The brake pedal 53 has an arm portion 53a extending in the front-rear direction, a cylindrical portion (pedal pivot shaft portion) 53b extending in the vehicle width direction and provided at the rear upper part of the arm portion 53a, and a swinging plate portion (pedal end portion) 53c extending upward from the cylindrical portion 53b. A shaft member 54 is inserted through the cylindrical portion 53b of the brake pedal 53. The brake pedal 53 is swingably supported on the pivot frame 32 via the shaft member 54.

[0063] A spring stay 53e is fixed to the arm portion 53a. One end of a return spring (not shown) is engaged with the spring stay 53e. This return spring biases the brake pedal 53 toward its normal position (see solid line in Figure 1). Furthermore, when the brake pedal 53 is operated against the biasing force of this return spring, the brake pedal 53 moves toward the operating position (see dashed line in Figure 1).

[0064] A bent rod-shaped hook portion 53f is formed on the side of the spring stay 53e. One end of a switch spring (not shown) extending from a brake switch (not shown) is engaged with the hook portion 53f. When the brake pedal 53 is operated and the brake switch is pulled via the switch spring, the stop lamp 30 (see Figure 1) at the rear of the vehicle illuminates.

[0065] A metal cover member 70 is supported on the pivot frame 32. The cover member 70 extends parallel to the pivot frame 32. The cover member 70 is positioned along the right side of the pivot frame 32.

[0066] The cover member 70 has a plate-shaped main body portion 71 that extends in the vertical direction. An upper support portion 72 and a lower support portion 73, both having a hole shape, are formed at the top and bottom of the main body portion 71. A bent plate-shaped spring engagement stay 74 that extends downward and rearward is fixed to the middle of the main body portion 71 in the vertical direction.

[0067] The spring engagement stay 74 is fixed to the inner surface of the main body 71, for example, by welding. A spring engagement portion 74a with a notch is formed at the rear end of the spring engagement stay 74. A plate support shaft (oscillating shaft) 75 is provided in front of the spring engagement stay 74. The plate support shaft 75 protrudes inward in the vehicle width direction from the inner surface of the main body portion 71.

[0068] The upper support portion 72 of the cover member 70 is fastened together with the swing arm 16 by the pivot shaft 22. Therefore, the support strength and rigidity of the cover member 70 can be ensured by utilizing the pivot shaft 22, which extends in the vehicle width direction and is firmly supported. A bolt (not shown) is inserted through the lower support portion 73 from the right side, and this bolt is fastened to the pivot frame 32.

[0069] Figure 10 is a right side view showing the peripheral part of the CBS mechanism 100. Figure 11 is a view of the peripheral part of the equalizer 111 of the CBS mechanism 100, seen from the front. The CBS mechanism 100 is positioned below the pivot axis 22 in a side view of the vehicle body (see Figures 1 and 9). The CBS mechanism 100 is positioned between the pivot frame 32 and the cover member 70. The CBS mechanism 100 is positioned on the outside in the vehicle width direction of the pivot frame 32.

[0070] The CBS mechanism 100 has an equalizer 111. The equalizer 111 is supported by the oscillating plate portion 53c of the brake pedal 53. The equalizer 111 extends in the vertical direction. The equalizer 111 is tilted backward as it extends upward. The equalizer 111 has an equalizer oscillating shaft portion 111a in the middle of the vertical direction. A connecting pin 121 extending in the vehicle width direction is inserted through the equalizer oscillating shaft portion 111a. As a result, the equalizer 111 is oscillatingly supported by the oscillating plate portion 53c.

[0071] More specifically, as shown in Figure 11, the connecting pin 121 is welded and fixed to the oscillating plate portion 53c of the brake pedal 53. A hole 121a is formed at the tip of the connecting pin 121, into which a retaining element 141 is fitted. The connecting pin 121 is then inserted through the equalizer oscillating shaft portion 111a, a washer 151 is fitted to the tip of the connecting pin 121, and the retaining element 141 is fitted to the hole 121a. As a result, the equalizer 111 is oscillatingly connected to the connecting pin 121 of the oscillating plate portion 53c.

[0072] The equalizer 111 has a rear brake rod connecting portion 111b above the equalizer pivot shaft portion 111a. The equalizer 111 has a link connecting portion 111c below the connecting pin 121. The link rod 112 is pivotably connected to the link connecting portion 111c. The link rod 112 extends in the front-rear direction. A connecting pin (pivot shaft) 122 extending in the vehicle width direction is provided at the front end (one end in the extension direction) of the link rod 112. A connecting pin (pivot shaft) 123 extending in the vehicle width direction is provided at the rear end (the other end in the extension direction) of the link rod 112. The connecting pins 122 and 123 are welded and fixed to the link rod 112.

[0073] The link rod 112 is pivotably connected to the equalizer 111 by inserting the connecting pin 122 at the front end of the link rod 112 into the link connecting portion 111c and securing it in place. Specifically, the connecting pin 122 of the link rod 112 is inserted into the equalizer 111, a washer 152 is attached to the tip of the connecting pin 122, and a retaining pin 142 is attached to the hole 122a. As a result, the link rod 112 is pivotably connected to the equalizer 111.

[0074] Furthermore, the connecting pin 123 at the rear end of the link rod 112 is inserted through the link connecting portion 113a of the link plate 113 to prevent it from coming loose, thereby allowing the link rod 112 to pivotably connect to the link plate 113. The connecting pin 123 of the link rod 112 is also prevented from coming loose by the washer 153 and retainer 143, allowing it to pivotably connect to the link plate 113.

[0075] The link plate 113 has a block shape with three peaks. In other words, the link plate 113 of this embodiment is roughly L-shaped when viewed from the side of the vehicle body. The link plate 113 has a link connecting portion (first peak, peak) 113a to which the link rod 112 is connected, a cable connecting portion (second peak, peak) 113c that pivotably supports the interlocking brake cable 67, and a pivoting support portion (third peak, peak, plate pivoting shaft portion) 113b provided between the link connecting portion 113a and the cable connecting portion 113c.

[0076] The link plate 113 is rotatably supported by the swing support portion 113b on the plate support shaft 75 (see Figure 9) of the cover member 70. Therefore, the link plate 113 is supported by the pivot frame 32, which is the vehicle body frame 11, via the cover member 70. In other words, the link plate 113 is swingably supported on the vehicle body, which is composed of the vehicle body frame 11 and the power unit 12, etc.

[0077] A delay spring 120 is connected to the link plate 113. The delay spring 120 is a coil-shaped tension spring. In this embodiment, one end of the delay spring 120 is connected to an engagement hole (engagement portion) 113d of the link plate 113. The engagement hole 113d is provided in the link plate 113 between the link connecting portion 113a and the swing support portion 113b. The other end of the delay spring 120 is hooked onto a spring engagement portion 74a of the cover member 70. As a result, the delay spring 120 biases the link plate 113 in a counterclockwise direction around the plate support shaft 75 when viewed from the right side of the vehicle body (see Figure 10). The delay spring 120 delays the timing at which the link plate 113 pulls the interlocking brake cable 67 when the brake pedal 53 is operated.

[0078] A stopper contact portion (stopper) 113e is formed at the rear end of the link plate 113. The stopper contact portion 113e contacts the stopper receiving portion 76 (see Figure 9) of the cover member 70, thereby restricting its rotation. This prevents the link plate 113, which is biased by the delay spring 120, from rotating excessively.

[0079] The rear brake rod 66 is pivotably connected to the rear brake rod connecting portion 111b of the equalizer 111 via a connecting pin 124 that extends in the vehicle width direction.

[0080] A pivoting member 131 is pivotably connected to the cable connection portion 113c of the link plate 113 via a connecting pin 125 that extends in the vehicle width direction. An interlocking brake cable 67 is connected to the pivoting member 131. In detail, the interlocking brake cable 67 is connected from above. The outer cable 67a of the interlocking brake cable 67 is appropriately supported by the vehicle frame 11. The inner cable 67b of the interlocking brake cable 67, which is led downward from the outer cable 67a, is pivotably connected to the link plate 113 via the pivoting member 131.

[0081] In the CBS mechanism 100, when the brake pedal 53 is operated, the equalizer 111, link rod 112, and link plate 113 are configured to move while maintaining various balances.

[0082] In an axial view of the connecting pin 123 (see Figure 10), a state is maintained in which the first line segment L1, which connects the axis Q0 of the plate support shaft 75 in the link plate 113 and the axis Q3 of the connecting pin 123 to which the link rod 112 is connected, and the second line segment L2, which connects the axis Q2 of the connecting pin 122 to which the equalizer 111 is connected in the link rod 112 and the axis Q3 of the connecting pin 123 to which the link plate 113 is connected, form an acute angle θ.

[0083] In this CBS mechanism 100, when the brake pedal 53 is operated, the oscillating plate portion 53c moves forward, and the connecting pin 121 fixed to the oscillating plate portion 53c also moves forward. Therefore, when viewed from the right side of the vehicle body, the equalizer 111 attempts to move forward as a whole together with the connecting pin 121. At this time, the lower link connecting portion 111c of the equalizer 111 is biased rearward by the delay spring 120 via the link rod 112 and the link plate 113.

[0084] Therefore, as the equalizer 111 attempts to rotate clockwise with respect to the connecting pin 121, the rear brake rod connecting portion 111b above the connecting pin 121 moves forward. That is, the rear brake rod 66 moves forward, and the rear wheel brake 64 is activated.

[0085] When the brake pedal 53 is operated further, the entire equalizer 111 moves forward as the oscillating plate portion 53c moves forward. Consequently, the link rod 112 also moves forward. At this time, the link connecting portion 113a of the link plate 113, to which the link rod 112 is connected, moves forward against the biasing force of the delay spring 120. Consequently, the link plate 113 rotates clockwise with respect to the plate support shaft 75.

[0086] Consequently, the cable connection portion 113c of the link plate 113 rotates downward, and the inner cable 67b of the interlocking brake cable 67 is pulled downward. Because the inner cable 67b is pulled, the knocker 87 rotates via the adjustment mechanism 90, pressing the piston rod 82 of the master cylinder unit 80, and the front wheel brake 61 is activated. When the brake pedal 53 is released, the brake pedal 53 returns to its normal position (see solid line in Figure 1) due to a biasing force such as a return spring (not shown).

[0087] In the CBS mechanism 100 of this embodiment, a portion of the equalizer 111, the link rod 112, and the link plate 113 are positioned below the connecting pin 121 of the oscillating plate portion 53c of the brake pedal 53. In particular, the equalizer 111, the link rod 112, and the link plate 113 are positioned so that their positions in the vertical direction overlap. Therefore, the CBS mechanism 100 can be easily arranged compactly.

[0088] As described above, according to this embodiment to which the present invention is applied, the device comprises a main frame 31 extending rearward from the head pipe 18, a pivot frame 32 extending downward from the main frame 31, a brake pedal 53 pivotably supported on the pivot frame 32 via a cylindrical portion 53b, and a CBS mechanism 100 that applies braking force to the front wheel 13 and rear wheel 15 in response to the operation of the brake pedal 53, wherein the CBS mechanism 100 is connected to an equalizer 111 and the front wheel, to which a rear brake rod 66 that operates the rear wheel brake 64 is connected. In a saddle-type vehicle 10, which includes a link plate 113 to which an interlocking brake cable 67 that operates a brake 61 is connected, the brake pedal 53 includes a swinging plate portion 53c extending from a cylindrical portion 53b, and the CBS mechanism 100 includes an equalizer 111 that is swingably supported on the swinging plate portion 53c, a link plate 113 that is swingably supported on the vehicle body which is composed of a vehicle frame 11 and a power unit 12, and a link rod 112 that connects the equalizer 111 and the link plate 113. In this configuration, in a CBS mechanism 100 in which an equalizer 111 to which a rear brake rod 66 is connected and a link plate 113 to which an interlocking brake cable 67 is connected are provided as separate components, the complexity of the configuration can be suppressed by supporting the link plate 113 on the vehicle body.

[0089] In this embodiment, the link plate 113 is pivotably supported on the vehicle body below the equalizer 111. With this configuration, since the link plate 113 is positioned below the oscillating plate portion 53c, the components of the CBS mechanism 100, which are connected from the oscillating plate portion 53c to the link plate 113, can be easily arranged to overlap with the oscillating plate portion 53c in a side view of the vehicle, and the CBS mechanism 100 can be arranged compactly.

[0090] In this embodiment, the equalizer 111 includes an equalizer pivot shaft portion 111a that is pivotably supported on the pivot plate portion 53c, and the equalizer 111 has a rear brake rod 66 connected to the upper part of the equalizer pivot shaft portion 111a and a link rod 112 connected to the lower part of the equalizer pivot shaft portion 111a. With this configuration, the rear brake rod 66 extending towards the rear wheel 15 extends from above the equalizer pivot shaft portion 111a, making it easier to create space below and rear of the equalizer pivot shaft portion 111a. This allows the components of the CBS mechanism 100 to be placed in the space below and rear, enabling a compact arrangement of the CBS mechanism 100.

[0091] In this embodiment, the link plate 113 is equipped with a swingable support portion 113b that is swingably supported on the vehicle body, and the link plate 113 has an interlocking brake cable 67 connected to the front of the swingable support portion 113b, and a link rod 112 connected to the rear of the swingable support portion 113b. With this configuration, the linked brake cable 67 extending to the front wheel 13 is positioned at the front, and the link rod 112 connecting the equalizer 111 and the link plate 113 is positioned using the space at the rear and lower side of the CBS mechanism 100, allowing the CBS mechanism 100 to be compactly arranged.

[0092] Furthermore, in this embodiment, the CBS mechanism 100 is positioned on the outside in the vehicle width direction of the pivot frame 32 and includes a cover member 70 that covers the CBS mechanism 100 from the outside in the vehicle width direction, and the link plate 113 is pivotably supported by the cover member 70. This configuration allows the CBS mechanism 100 to be protected from the outside in the vehicle width direction, and makes it easier to position the plate support shaft 75, which is the pivot axis of the link plate 113, away from the components of the CBS mechanism 100. This also makes it easier to set the position of the plate support shaft 75 regardless of the range of movement of the components of the CBS mechanism 100.

[0093] In this embodiment, the link plate 113 also includes an engagement hole 113d into which the delay spring 120 engages, and a stopper portion 113e that restricts the swinging of the link plate 113. With this configuration, the force of the delay spring 120 and the force of the stopper portion 113e act directly on the link plate 113, thus enabling precise oscillation of the link plate 113.

[0094] Furthermore, in this embodiment, in an axial view, a first line segment L1 connecting the axis Q0 of the pivot support portion 113b and the axis Q3 of the connecting pin 123 to which the link rod 112 is connected, and a second line segment L2 connecting the axis Q2 of the connecting pin 122 to which the equalizer 111 is connected and the axis Q3 of the connecting pin 123 to which the link plate 113 is connected, form an acute angle θ. This configuration makes it easier to reduce the vertical size of the CBS mechanism 100, allowing the CBS mechanism 100 to be arranged compactly.

[0095] [Other embodiments] The embodiments described above represent only one aspect of the present invention and can be modified and applied as needed without departing from the spirit of the invention.

[0096] In the above embodiment, a saddle-type vehicle 10 having a power unit 12 as an internal combustion engine was exemplified, but it is not limited to this. For example, the saddle-type vehicle 10 may be a vehicle that does not have a power unit 12 as an internal combustion engine, i.e., an electric vehicle. Therefore, in the above embodiment, a power unit 12 was exemplified as the power unit that drives the vehicle body, but the power unit may be a power unit equipped with an electric motor for driving. In this case, the saddle-type vehicle as an electric vehicle is equipped with a battery for driving the power unit instead of a fuel tank 29.

[0097] In the above embodiment, a configuration was described in which the pivot frame 32 is formed in the shape of a bent plate and fixed to the rear end of the main frame 31. However, the shape of the pivot frame 32 is not limited to this. For example, the pivot frame 32 may be formed to extend continuously from the main frame 31 and be integral to the appearance of the main frame 31.

[0098] In the above embodiment, a motorcycle having a front wheel 13 and a rear wheel 15 was used as an example to describe the saddle-type vehicle 10. However, the present invention is not limited thereto, and can be applied to three-wheeled saddle-type vehicles having two front or rear wheels, or saddle-type vehicles having four or more wheels.

[0099] [Configurations supported by the above embodiment] The above embodiment supports the following configuration.

This configuration allows the CBS mechanism to be protected from the outside in the vehicle width direction, makes it easier to position the pivot axis of the link plate away from the components of the CBS mechanism, and makes it easier to set the position of the pivot axis regardless of the range of movement of the components of the CBS mechanism.

[0105] (Configuration 6) The saddle-type vehicle according to any one of Configurations 1 to 5, characterized in that the link plate comprises an engagement portion into which a delay spring engages, and a stopper that restricts the swinging of the link plate.

This configuration makes it easier to reduce the vertical size of the CBS mechanism, allowing for a more compact arrangement of the CBS mechanism. [Explanation of symbols]
