Conventionally, brake devices have been used in straddle-type vehicles, such as motorcycles, which actuate a front wheel brake and a rear when one of the two brake levers provided on both the left and right handlebars is operated. Both of the rims, and they only actuate the front wheel brakes while the other brake lever is being operated. In the brake device, the brake lever (hereinafter referred to as "linking brake lever") for actuating both the front wheel brake and the rear wheel brake is connected to the rear wheel brake and includes a master cylinder and other materials for use by hydraulic pressure. A front wheel brake actuating mechanism that activates the front wheel brake (for example, see Patent Document 1).

[Patent Document 1] JP-A-Heilo-167154

However, in the conventional brake device, the front wheel brake actuating mechanism is disposed away from the interlocking brake lever, and thus an operating force sometimes suffers a transmission loss in the transmission path of the operating force from the linked brake lever to the front wheel brake actuation mechanism. .

For example, in the brake device disclosed in Patent Document 1, the front wheel brake actuation mechanism is disposed on the handlebar opposite to the handlebar on which the brake lever is located (the two handlebars are left and right handlebars), so that linkage The operating force of the brake lever is transmitted to the front wheel brake actuating mechanism via a cable. Therefore, there is a transmission loss due to the friction between the inner cable and the outer cable.

The present invention has been made in view of the above problems, and it is therefore an object to provide a transmission of an operating force from a linkage brake lever to a front wheel brake actuation mechanism. The transport path has a brake device that reduces transmission loss, and a straddle-type vehicle.

In order to achieve the above object, the present invention provides a brake device comprising: a front wheel brake lever provided on one of the handlebars; and a linkage provided on the other of the handlebars and connected to a rear wheel brake a front wheel brake actuating mechanism disposed on the other of the handlebars adjacent to the linked brake lever for operating the force by one of the front wheel brake lever or the linked brake lever Generating a fluid pressure in a hydraulic path of a front wheel brake to actuate the front wheel brake; and an operating force transmitting member extending from the one of the handlebars to the other to cause the front wheel to brake the lever The operating force is transmitted from the one of the handlebars to the other one prior to inputting the front wheel brake actuation mechanism.

The present invention also proposes a straddle type vehicle including the above brake device.

According to the present invention, it is possible to realize a brake device having a reduced transmission loss in a transmission path from a linkage brake lever to a front wheel brake actuation mechanism. The straddle type vehicle may be, for example, a motorcycle (including a speed-up locomotive), a four-wheeled truck (buggy) or the like.

In one aspect of the invention, a play for delaying transmission of the operating force from the linkage brake lever to the front wheel brake actuation mechanism may be provided between the linkage brake lever and the front wheel brake actuation mechanism . According to this aspect, when the linked brake lever is operated, it is possible to actuate the rear brake faster than the front brake.

In another aspect of the invention, the front wheel brake actuation mechanism includes a main a cylinder and an arm, the arm receiving the operating force of the front wheel brake lever or the linkage brake lever is pressed by the receiving operation force to generate a fluid pressure in the hydraulic path, and the arm is configured as a The operating force is displaceable relative to the operating force transmitting member from the input of the linked brake lever to the arm. According to this aspect, it is possible to suppress the transmission of the operating force of one of the linked brake levers to the side of the front wheel brake lever.

In still another aspect of the present invention, the brake device may further include: a rear wheel brake cable for transmitting an operating force of the one of the linked brake levers to the rear wheel brake; and an input member Receiving the operating force of the interlocking brake lever to pull the rear wheel brake cable and input the operating force to the front brake actuation mechanism, and the input member may be attached to the linkage brake lever.

In this aspect, the input member can be provided to receive a reaction force displacement from the front wheel brake actuation mechanism when the linkage brake lever is operated, and the rear wheel brake cable is resistant to receipt by the input member The reaction force suppresses displacement of the input member such that the input member inputs the operating force of the linked brake lever to the front wheel brake actuating mechanism against the reaction force in a state where the displacement of the input member is suppressed. According to this configuration, it is possible to prevent an operation force of one of the linked brake levers from inputting the front wheel brake lever actuating mechanism from the input member when the rear wheel brake cable is damaged.

In this aspect, the input member may have a support portion to be supported by the rear wheel brake cable and an operation force input portion for inputting the operation force of the linked brake lever into the front wheel brake actuation mechanism, and may be attached Connected to the interlocking lever for rotatably shifting. The support portion may constitute a rotation displacement of the input member by being supported by the rear wheel brake cable, and one from the The distance from one of the rotational displacements of the member to the operating force input portion is less than the distance from the center to the support portion. With this configuration, it is possible to increase an operating force input from the interlocking lever to the front wheel brake actuating mechanism via the input member.

In this aspect, the input member can be an equalizer, and the equalizer can have a rotary support portion to be supported by the linkage brake lever, and a position to be pulled away from the rotary support portion. A cable attachment portion of the rear wheel brake cable is provided, and an operation force input portion for inputting the operation force of the interlocking brake lever to the front wheel brake actuation mechanism at a position away from the rotation support portion. According to this configuration, it is possible to use the equalizer to divide the operating force of one of the linked brake levers into a force to be input to the front wheel brake via the front wheel brake actuating mechanism and to input the rear wheel via the rear wheel brake cable The force of the brakes is suppressed, and the proportional change is suppressed. In this case, the rotary support portion of the input member may be provided between the operating force input portion and the cable attachment portion.

According to this aspect, it is possible to delay the transmission of the operating force of one of the linked brake levers from the front wheel brake actuating mechanism to the front wheel brake, and to actuate the rear wheel brake earlier than the front wheel brake.

In still another aspect of the invention, the operating force transmitting member is a rod extending from one of the handlebars toward the other. Because the rod will not be compared to the cable As time passes, it becomes longer, and one rod is used as an operation force transmitting member, that is, it is not necessary to perform length adjustment work by a user and a length adjusting mechanism. Therefore, it is possible to prevent the user from making an incorrect adjustment. For example, it is possible to prevent the user from adjusting the operating force transmitting member to a length such that a hydraulic pressure is always generated in the liquid path by the front wheel brake actuating mechanism.

In this aspect, the lever can be coupled to the front wheel brake actuation mechanism and a coupling portion provided to the front wheel brake lever, and the lever can be provided with an adjustment mechanism for adjusting the front wheel brake actuation mechanism and the coupling One of the distances between the rooms. According to this configuration, it is possible to set an appropriate distance between the coupling portion and the front wheel brake actuating mechanism.

In this manner, the interlocking brake lever 40 is rotatable about the journal member 43. As shown in FIG. 6, a nut 44 is fitted to the distal end of the journal member 43 via a washer 45.

As shown in FIG. 7, the base portions 40c, 40d have respective rotation support portions 40b, 40b for supporting the rotation member 42 to be rotatable. The rotary support portions 40b, 40b are positioned in front of the respective rotary support portions 40a, 40a (as seen in the direction away from the handlebar 4). Specifically, the rotary support portions 40b, 40b are also provided with corresponding holes 40h, 40h at positions facing each other. The rotating member 42 is also provided with a hole 42g at a position corresponding to the holes 40h, 40h (see Fig. 9). As shown in FIG. 4, the rotating member 42 is disposed between the upper and lower base pairs 40c, 40d, and a journal member (here, a bolt) 46 passes through the hole 42g of the rotating member 42 and the holes 40h, 40h. In this way, the rotary support portions 40b, 40b will rotate Member 42 is supported for rotation. As shown in FIG. 6, a washer 47 is fitted to the distal end of the journal member 46. A retaining member (here an open tail pin) 48 passes through the distal end of the journal member 46 to secure the journal member 46 to the associated brake lever 40.

As shown in FIG. 6 or FIG. 7, the base portion 40d is provided with a stopper 40f that protrudes downward. On the other hand, as shown in FIGS. 5 to 8, the master cylinder 32 is provided with a rotation restricting portion 32c that protrudes forward, and the rotation restricting portion 32c is positioned in a non-operating state (the interlocking lever 40 is not operated). The state of rotation) interlocks the position of the stopper 40f of the brake lever 40. The rotation restricting portion 32c restricts the rotation of the interlocking lever 40 by contacting the stopper 40f in a state in which the interlocking lever 40 is not operated.

The rotating member 42 will be described below. As shown in FIG. 5 or FIG. 9, the rotating member 42 is disposed to extend from the rotation supporting portion 40b toward the center in the vehicle width direction (direction C in FIG. 5), and has a rotation supporting portion 42a, a cable attachment portion 42b, and One arm presses the portion 42c.

One end of the rear wheel brake cable 11 is attached to the cable attachment portion 42b. In the present example, as shown in Fig. 6, a cylindrical engaging portion 11d is provided at the corresponding end of the inner cable 11a. On the other hand, a recess for accommodating the cylindrical engaging portion 11d is formed in the cable attachment portion 42b, allowing the engaging portion 11d and the cable attaching portion 42b to be engaged with each other. As shown in Fig. 9, a notch 42e is formed in the cable attachment portion 42b. The inner cable 11a extends toward the center in the vehicle width direction through the notch 42e.

The arm pressing portion 42c is formed at a position facing one of the lever-side pressed portions 31c of the arm 31 (see below). In the present example, as shown in Fig. 5, the arm pressing portion 42c is formed to extend from the rotation supporting portion 42a toward the grip 4b.

As previously mentioned, the rotating member 42 is provided to be rotatable about the journal member 46. The rear wheel brake cable 11 resists the rotation (retraction) of the rotation member 42 receiving a reaction force from the arm 31 when the interlocking brake lever 40 is operated. The rotating member 42 inputs an operating force of the interlocking brake lever 40 to the arm 31 against the reaction force in a state where the rotation of the rotating member 42 is adjusted. That is, the cable attachment portion 42b is pulled by the inner cable 11a toward the center in the vehicle width direction to adjust the rotation of the rotary member 42. When the interlocking lever 40 is operated, the rotating member 42 is supported by the inner cable 11a on the arm 31 side, and the arm pressing portion 42c resists the reaction force received from the arm 31 to input an operating force of the interlocking lever 40 to the arm 31. .

When the knight performs a braking operation, the pressed portion 32a is pressed by a cylinder pressing portion 31a (see below) of the arm 31 to apply pressure to a piston (not shown) housed in the master cylinder 32. Then, the pressed portion 32a raises the hydraulic pressure of the brake oil in the hydraulic path 12 to actuate the front wheel brake 14. In the present example, the end surface of the pressed portion 32a faces the lateral direction in the vehicle width direction (in the direction opposite to the direction A shown in Fig. 3) such that the end surface of the pressed portion 32a faces the cylinder pressing portion 31a of the arm 31 (see Figure 5). The pressed portion 32a is urged laterally in the vehicle width direction by a spring (not shown) housed in the master cylinder 32.

The lever supporting portions 32d, 32d support the interlocking lever 40 and the arm 31 to be rotatable. In the present example, one of the arms 31 is provided with a rotary support portion 31d (see below) between the rotary bearing portions 40a, 40a of the interlocking brake lever 40 (see Fig. 11), and the rotary support portions are disposed on the upper and lower levers. The support portion is between 32d and 32d. The rod supporting portions 32d, 32d are provided with the aforementioned respective holes 32b, 32b (see Fig. 8). The journal member 43 passes through the holes 32b, 32b, interlocking the holes 40g, 40g of the brake lever 40 and the hole 31b of the arm 31 (see below). In this manner, the interlocking lever 40 and the arm 31 are supported to be rotatable by the lever supporting portions 32d, 32d. A washer 44 and a nut 45 are fitted to one end of the journal member 43 (see Fig. 6).

The stop light switch 35 is open when the interlocking brake lever 40 is not operated, and the stop light switch 35 is pressed by the stopper 40f of the brake lever 40. When the rider performs a brake operation, the stop light switch 35 is turned on and its The stoppers 40f are separated.

Next, the arm 31 will be described. As shown in Fig. 11, the arm 31 includes a cylinder pressing portion 31a, a rotation supporting portion 31d, a rod side pressure receiving portion 31c, and a tension portion 31e.

The hole 31b is formed at the center of the rotation support portion 31d, and the journal member 43 passes through the hole 31b as described above. When an operating force is input from the interlocking brake lever 40 or the front wheel brake lever 20, the arm 31 is rotated about the journal member 43 to press the cylinder pressing portion 31a toward the pressed portion 32a of the master cylinder 32.

The arm 31 has a raised portion 31f extending laterally from the rotary support portion 31d. One side of the swelled portion 31f presses the portion 42c toward the arm of the rotating member 42, and functions as a rod side pressed portion 31c (see Fig. 5).

One for delaying an operating force from the interlocking brake lever 40 to the brake actuation mechanism 30 The transmitted play is provided between the linked brake lever 40 and the arm 31. In this example, as shown in Fig. 5, when the interlocking brake lever 40 is in the non-operating state, a clearance h is provided as a play between the lever side pressure receiving portion 31c and the arm pressing portion 42c of the rotating member 42.

The cylinder pressing portion 31a is provided on the side opposite to the rod side pressure receiving portion 31c across the rotation supporting portion 31d. Specifically, the arm 31 has a raised portion 31g which is laterally raised from the rotary support portion 31d, and the cylinder pressing portion 31a is provided on one side of the raised portion 31g, facing the pressed portion 32a of the master cylinder 32. The distance from the center of the hole 31b to the cylinder pressing portion 31a is shorter than the distance from the center of the hole 31b to the rod side pressure receiving portion 31c. The raised portion 31f, the rotating support portion 31d, and the raised portion 31g constitute a thick plate.

The tension portion 31e is provided at a position separated from the ridge portion 31f, the rotation support portion 31d, and the ridge portion 31g in the vertical direction (in the direction D shown in Fig. 11), and faces the ridge portion 31g in the vertical direction.

A pulling portion 21c at one end of the inner cable 21a of the transmission cable 21 is held by the tension portion 31e (see Fig. 4). The pulling portion 21c is configured to pull the tension portion 31e to transmit the movement of the front wheel brake lever 20 to the front wheel brake actuation mechanism 30 when the front wheel brake lever 20 is operated, and to move away from the tension portion 31e when the linkage brake lever 40 is operated. The movement of the linked brake lever 40 is not transmitted to the front wheel brake lever 20 for a distance.

Specifically, as shown in Fig. 4, the pulling portion 21c has a base portion 21d and a pair of plates 21e, 21e extending perpendicularly from the base portion 21d. The plates 21e, 21e are provided with corresponding holes 21f, 21f which are elongated in the moving direction of the tension portion 31e when the interlocking lever 40 is operated (see Figs. 4 and 6). On the other hand, like As shown in Fig. 11, a hole 31h is formed at the center of the tension portion 31e. The tensioned portion 31e is disposed between the pair of plates 21e, 21e, and a pin 22 passes through the hole 31h and the holes 21f, 21f. The tensioned portion 31e is held in engagement with the pulling portion 21c by the pin 22. In this manner, the arm 31 can be displaced relative to the transmission cable 21 when an operating force is input from the interlocking brake lever 40 to the arm 31 (when the linkage lever 40 is operated). That is, the tension portion 31e moves together with the pin 22 in the space between the plates 21e, 21e with respect to the inner cable 21a. In this manner, even in the case where the interlocking brake lever 40 is operated, the movement of the interlocking brake lever 40 is not transmitted to the front wheel brake lever 20.

As shown in FIG. 6, a washer 25 is fitted to the distal end of the pin 22. A retaining member (here an open tail pin) 26 passes through the distal end of the pin 22 on the outside of the washer 25. The holding member 26 prevents the pin 22 from slipping off the pulling portion 21c. A coil spring 28 is disposed between the base portion 21d of the pulling portion 21c and the transmission cable supporting portion 32g. The coil spring 28 applies a force in a direction in which the distance between the base portion 21d and the transmission cable supporting portion 32g is increased. The coil spring 28 is disposed to surround the inner cable 21a. A tube 27 having an outer diameter equal to the inner diameter of the coil spring 28 is attached to the inner cable 21a. The tube 27 stabilizes the position of the coil spring 28 with respect to the inner cable 21a to prevent the coil spring 28 from swaying to make an audible sound.

As shown in Fig. 11, the tensioned portion 31e and the raised portion 31g are coupled by a post 31i extending in the vertical direction. The arm 31 is continuously urged to keep the cylinder pressing portion 31a in contact with the pressed portion 32a of the master cylinder 32. In the present example, as shown in FIG. 6, a torsion spring 34 provides extension across the post 31i and the journal member 43 to pull the post 31i toward the master cylinder 32.

The operation of the brake device 10 will be described below. Figures 12 and 13 are used to explain when A diagram of the operation of the brake device 10 when the brake lever 40 is operated. Figure 14 is a view showing how the tension portion 31e of the arm 31 is moved between the plates 21e, 21e of the transmission cable 21. Figure 15 is a diagram for explaining the operation of the brake device 10 when the current rim lever 20 is operated. First, the operation of the brake device 10 when the interlocking brake lever 40 is operated will be described.

As described above, in the initial state shown in FIG. 5 (the state in which the brake operation is not performed), the arm pressing portion 42c of the rotating member 42 is partitioned by the rod side pressure receiving portion 31c of the arm 31 with the gap h.

When the knight starts operating the interlocking lever 40 as shown in Fig. 12, the interlocking lever 40 starts to rotate about the journal member 43 toward the grip 4b. Therefore, the inner cable 11a of the rear wheel brake cable 11 is pulled by the rotating member 42 to start the rear wheel brake 17 . At this time, only the arm pressing portion 42c of the rotating member 42 and the rod side pressed portion 31c of the arm 31 are in contact with each other; therefore, the arm 31 has not been rotated, and the front wheel brake 14 has not started to be actuated.

After that, when the knight further operates the interlocking lever 40 as shown in FIG. 13 and the interlocking lever 40 is rotated about the journal member 43 toward the grip 4b, the arm pressing portion 42c of the rotating member 42 is toward the rod side of the arm 31. The pressed portion 31c is pressed. Therefore, the arm 31 also rotates around the journal member 43, and the cylinder pressing portion 31a presses the pressed portion 32a of the master cylinder 32. In this way, the front wheel brake 14 begins to be actuated.

At this time, the pin 22 is moved along the holes 21f, 21f formed in the transmission cable 21 plates 21e, 21e as shown in Fig. 14, allowing the tension portion 31e of the arm 31 to move between the plates 21e, 21e of the transmission cable 21 without changing. Pull the position of the portion 21c. This prevents the operation of one of the linked brake levers 40 from being transmitted when the linked brake lever 40 is operated. Lost to the front wheel brake lever 20.

As described above, the distance L1 from the rotational displacement center P of the rotating member 42 to the arm pressing portion 42c is shorter than the distance L2 from the center P to the cable attachment portion 42b (see Fig. 10). With this configuration, the pressing force applied to the rod-side pressed portion 31c by the arm pressing portion 42c is increased, allowing the arm 31 to be rotated against the reaction force received from the rod-side pressure receiving portion 31c without being greatly rotated. (Retracting) the rotating member 42.

Next, the operation of the brake device 10 when the current rim lever 20 is operated will be described.

When the knight operates the front wheel brake lever 20, the front wheel brake lever 20 pulls the transmission cable 21, and the pulling portion 21c pulls the tension portion 31e of the arm 31. Therefore, as shown in Fig. 15, the arm 31 rotates around the journal member 43, and the cylinder pressing portion 31a presses the pressed portion 32a of the master cylinder 32. In this way, the front wheel brake 14 is actuated. At this time, the arm pressing portion 42c of the rotating member 42 and the rod side pressed portion 31c of the arm 31 are spaced apart from each other farther than the initial state.

Finally, the operation of the brake device 10 when the inner cable 11a of the rear wheel brake cable 11 is cut or released from the rotating member 42 will be described. Figure 16 is a view for explaining the operation of the brake device 10 when the inner cable 11a is released from the rotating member 42.

When the kiosk operates the interlocking lever 40 in a state where the inner cable 11a is released from the rotating member 42, the interlocking lever 40 rotates around the journal member 43 toward the grip 4b as shown in FIG. At this time, the arm pressing portion 42c of the rotating member 42 is in contact with the rod side pressed portion 31c of the arm 31. However, the rotating member 42 is rotated (retracted) around the journal member 46, and thus the arm pressing portion 42c of the rotating member 42 cannot press the rod side pressed portion 31c against the expansion force of the spring housed in the master cylinder 32. This prevents When the interlocking brake lever 40 is operated while the inner cable 11a is released from the rotating member 42, only the front wheel brake 14 is actuated.

In the above-described brake device 10, the front wheel brake actuating mechanism 30 is disposed in the vicinity of the interlocking brake lever 40. Therefore, it is possible to reduce an operating force as compared with the case where the interlocking brake lever and the front wheel brake actuating mechanism are disposed apart from each other and the operation of interlocking the brake lever is transmitted to the front wheel brake actuating mechanism via a wire or the like. The transmission loss in the transmission path from the interlocking brake lever 40 to the front wheel brake actuation mechanism 30 at an operating force.

The present invention is not limited to the above-described brake device 10, and various modifications can be made thereto. For example, in the above description, the rear wheel brake cable 11 is coupled to the interlocking brake lever 40 via the rotating member 42. However, the rear wheel brake cable can also be directly connected to the linked brake lever. Figure 17 is a plan view showing a brake device 10A as an example of a brake device according to this embodiment. In FIG. 17, portions similar to those described above will be given similar reference numerals and will not be described again.

The brake device 10A includes a linkage brake lever 40A and a rotating member 42A. The interlocking brake lever 40A includes a cable attachment portion 40k, and the engaging portion 11d of the rear wheel brake cable 11 is held by the cable attachment portion. A pulling force from the coil spring 11c acts on the inner cable 11a of the rear wheel brake cable 11 (see Fig. 1). The interlocking brake lever 40A has a rotation support portion 40L. The rotation support portion 40L is positioned at the cable attachment portion 40k and the rod side pressure receiving portion 31c of the arm 31, and supports the rotation member 42A to be rotatable. The rotating member 42A has a rotation supporting portion 42h, and a journal member (for example, a bolt) 46 passes through the rotating support portion 42h and the rotating support portion 40L of the interlocking lever 40A. The rotating member 42A also has a cable side supporting portion 42i. Cable side support portion 42i and receiving The inner cable 11a is in contact with the pulling force. This restricts the rotation (retraction) of the rotating member 42A in the direction away from the side where the arm 31 is located.

Next, the operation of the brake device 10A will be described. When the interlocking brake member 40A is rotated by the knight to the knight (toward the grip 4b), the arm pressing portion 42c of the rotating member 42A presses the rod-side pressed portion 31c of the arm 31, and The rod side pressure receiving portion 31c receives a reaction force. The inner cable 11a of the rear wheel brake cable 11 is in contact with the cable side support portion 42i, and the rotary member 42A is supported on the side of the rod side pressure receiving portion 31c against the reaction force received by the rotary member 42A from the arm 31. Since the rotating member 42A is supported by the inner cable 11a, the rotating member 42A presses the rod side pressed portion 31c without rotating in the reverse direction (direction E in Fig. 17), and inputs the operating force of the interlocking brake lever 40A to the arm 31. .

Next, the operation of the brake device 10A in a state where the inner cable 11a is not connected will be described. In a state where the inner cable 11a is not connected, the rotating member 42A is allowed to rotate in the direction opposite to the side where the arm 31 is located. Therefore, as in the example described with reference to Fig. 16, when the interlocking lever 40A is rotated toward the knight, the arm pressing portion 42c of the rotating member 42A receives a reaction force from the rod side pressed portion 31c of the arm 31, and the rotating member 42A cannot The reaction is reversed in the direction of the rod-side pressed portion 31c (direction E in Fig. 17). In this manner, it is possible to prevent only the front wheel brake 14 from being actuated in the case where the interlocking brake lever 40A is operated when the inner cable 11a is not connected. The operation of the brake device 10A has been as described above.

In the aforementioned braking device 10, a gap h is provided between the rod-side pressed portion 31c of the arm 31 and the arm pressing portion 42c of the rotating member 42 (see Fig. 5). This gap delays the actuation of the front wheel brake 14 when the linked brake lever 40 is operated. At the beginning of the operation of the rear wheel brakes 17. However, the mechanism for delaying the operation of the front wheel brake 14 is not limited thereto. For example, a force may be applied to the arm 31 in a direction opposite to the direction of movement of the arm 31 to delay the actuation of the front wheel brake 14.

In the aforementioned braking device 10, the rotating member 42 is regarded as a member that inputs an operating force of the interlocking lever 40 to the arm 31. However, an equalizer can also be used as a member for inputting an operating force of the linked brake lever 40 to the arm 31.

Figure 18 is a plan view showing a brake device 10B as an example of a brake device according to this embodiment. Figure 19 is an exploded perspective view of an equalizer 64 and an arm 61 of a brake device 10B. Figure 20 is a plan view of an equalizer 64 and an arm 61. 21 is an enlarged view of an equalizer 64. Figure 22 is a perspective view of a master cylinder 32B of a brake device 10B as viewed from the front. In these drawings, portions similar to those of the aforementioned brake device 10 will be given similar reference numerals and will not be described again. In the brake device 10B, the arm 61 and the master cylinder 32B constitute a front wheel brake actuating mechanism 30B.

As shown in FIG. 18, in addition to the equalizer 64 and the arm 61, the brake device 10B further includes a linkage brake lever 40B and a biasing member 65 for previously moving in the opposite direction of the arm 61 during the braking operation. Apply a force to the direction. The arm 61 includes a lever side arm 62 and a cylinder side arm 63 that is rotatable independently of the lever side arm 62 (see Fig. 19).

The cylinder side arm 63 is rotated by the lever side arm 62 or pulled by the transmission cable 21 as described above, thereby pressing the pressure receiving portion 32a of the master cylinder 32B. As shown in Fig. 19, the cylinder side arm 63 has a cylinder pressing portion 63a, a pair of upper and lower rotation supporting portions 63d, 63d, a pressed portion 63c, and a tension portion 63e. Rod The side arm 62 has a rotation support portion 63d, a rod side pressure receiving portion 62c, a pressing portion 62a, a stopper 62e, and a biasing member attachment portion 62f.

As shown in Fig. 20, the pressing portion 62a of the rod side arm 62 faces the pressed portion 63c of the cylinder side arm 63, and is pressed toward the pressed portion when the rod side pressed portion 62c of the rod side arm 62 is pressed by the equalizer 64 63c pressure. This causes the lever side arm 62 and the cylinder side arm 63 to rotate together with each other.

The rod side pressure receiving portion 62c of the rod side arm 62 is pulled by the urging member 65 to the equalizer 64 to be in contact with the arm pressing portion 64c of the equalizer 64. In this example, the urging member 65 is an elastic member (for example, a spring) having a contracting force and extends between the rod side arm 62 and the master cylinder 32B (see Fig. 18). Specifically, the urging member attachment portion 62f of the rod side arm 62 protrudes upward from the rod side pressure receiving portion 62c (see FIG. 19), and one end of the urging member 65 is attached to the urging member attachment portion 62f. The master cylinder 32B is provided with a biasing member attachment portion 32j. As shown in Fig. 22, in the master cylinder 32B, the urging member attachment portion 32j is formed to extend forward in the middle portion of the rear wheel brake cable supporting portion 32h. The force applying member attachment portion 32j is a protruding portion that protrudes upward, and the other end of the urging member 65 is attached to the urging member attachment portion 32j. The urging member 65 pulls the urging member attachment portion 62f of the lever side arm 62 in a direction opposite to the direction in which the lever side arm 62 moves when the brake operation is performed.

As shown in Figs. 18 and 22, the master cylinder 32B has a positioning portion 32k which is slightly raised forward at a position facing the stopper 62e of the lever side arm 62. The stopper 62e is in contact with the positioning portion 32k (see Fig. 18), and the position of the lever side arm 62 is determined by restricting the rotation of the lever side arm 62 when being pulled by the biasing member 65. Set.

The cylinder pressing portion 63a, the rotation supporting portions 63d, 63d, and the tension portion 63e of the cylinder side arm 63 and the cylinder pressing portion 31a, the rotation supporting portion 31d, and the tension portion 31e of the arm 31 described above, respectively. That is, the cylinder pressing portion 63a comes into contact with the pressed portion 32a of the master cylinder 32B, and applies pressure to the pressure receiving portion 32a in response to an operating force of the interlocking lever 40B. The rotation support portion 62d of the lever side arm 62 is disposed between the pair of upper and lower rotation support portions 63d, 63d. As shown in Fig. 19, the rotary support portion 63d and the rotary support portion 62d of the lever side arm 62 are provided with holes 63b, 62b, respectively, and the journal member 43 passes through the holes 63b, 62b so that the lever side arm 62 and the cylinder side arm 63 can be Rotation around the journal member 43. The inner cable 21a of the transmission cable 21 is held by the tension portion 63e, so that the tension portion 63e is pulled by the inner cable 21a when the front wheel brake lever 20 is operated. In Fig. 18, the pulling portion 21c attached to one end of the inner cable 21a is not shown, and only the inner cable 21a is shown in a long double dashed line.

As shown in Fig. 19 or Fig. 20, the equalizer 64 has a rotary support portion 64a positioned at its center, a cable attachment portion 64b provided at a position away from the rotary support portion 64a, and a same also provided away from the rotary support. An arm pressing portion 64c at one position of the portion 64a, and a raised portion 64f. The engaging portion 11d of the rear wheel brake cable 11 is held by the cable attachment portion 64b as well as the cable attachment portion 42b of the aforementioned rotating member 42 (see Fig. 18 or Fig. 20). The rear wheel brake cable 11 pulls the cable attachment portion 64b by the elastic force of the coil spring 11c (see Fig. 1). The rotary bearing portion 64a is a hole through which the journal member 64 passes. The equalizer 64 is rotatable about the journal member 46. As shown in Fig. 20, the raised portion 64f is rotatably supported in a direction away from the cable attachment portion 64b. Part 64a is raised. The arm pressing portion 64c is formed on a wall portion of one of the swelled portions 64f opposite to the rod-side pressure receiving portion 62c of the rod side arm 62. The arm pressing portion 64c is positioned on the side opposite to the cable attachment portion 64b across the rotation support portion 64a and is in contact with the rod side pressure receiving portion 62c of the lever side arm 62. When the cable attachment portion 64b is pulled by the rear wheel brake cable 11, a rotational force about the journal member 46 acts on the equalizer 64. Therefore, the arm pressing portion 64c presses the rod side pressure receiving portion 62c.

In the present example, as shown in Fig. 21, the line P1 of the connection ridge portion 64f, the center P2 of the rotation support portion 64a, and the center P3 of the cable attachment portion 64b are substantially straight (the straight line L3 in Fig. 21). ). The inner cable 11a pulls the cable attachment portion 64b in a direction substantially perpendicular to the straight line L3 (direction V1 shown in the drawing). The arm pressing portion 64c presses the rod side pressure receiving portion 62c of the lever side arm 62 in a direction substantially perpendicular to the straight line L3 (direction V2 shown in the drawing).

As shown in Fig. 18, the interlocking lever 40B has a stopper 40i for limiting the amount of rotation of the equalizer 64 to a predetermined amount. Figure 23 is a front elevational view of the base portions 40c, 40d of a linkage brake lever 40B. As shown, the stopper 40i is a projection that protrudes from the base portion 40d toward the base portion 40c. As shown in Fig. 18, the stopper 40i is formed at a position slightly apart from the arm pressing portion 64c in the direction in which the arm pressing portion 64c of the equalizer 64 is moved when the interlocking lever 40B is operated.

The operation of the brake device 10B will now be described. 24 and 25 are diagrams for explaining the operation of the brake device 10B when the interlocking brake lever 40B is operated. Fig. 26 is a view for explaining the operation of the brake device 10B when the current rim lever 20 is operated. Figure 27 is a view for explaining the inner cable 11a of the rear wheel brake cable 11 A diagram of the operation of the brake device 10B when not connected. Figure 28 is a diagram for explaining the operation of the brake device 10B in the case where the oil leaks from the hydraulic path 12. In these drawings, the master cylinder 32B and the interlocking brake lever 40B are simplified, and the rotation restricting portion 32c of the master cylinder 32B and the stopper 40f of the interlocking brake lever 40B are not shown. The inner cable 11a of the rear wheel brake cable 11 is shown by a long double dashed line.

First, the operation of the brake device 10B when the interlocking brake lever 40B is operated will be described with reference to Figs. 24 and 25. When the interlocking lever 40B is pulled to the grip 4b as shown in Fig. 24 and starts to rotate, the equalizer 64 starts moving together with the interlocking lever 40B in the lateral direction of the vehicle width (direction W1 shown in the drawing). At this time, the cable attachment portion 64b of the equalizer 64 pulls the inner cable 11a of the rear wheel brake cable 11 outward in the vehicle width direction, and the arm pressing portion 64c presses the rod side pressure receiving portion 62c of the lever side arm 62. In this way, the rear wheel brake 17 begins to be actuated.

On the other hand, since the urging member 65 has previously pulled the urging member attachment portion 62f of the lever side arm 62, the front wheel brake 14 does not start to operate. That is, the urging member 65 pulls the urging member attachment portion 62f of the lever side arm 62 in a direction opposite to the direction in which the equalizer 64 presses the lever side arm 62. Therefore, the lever side arm 62 and the cylinder side arm 63 do not rotate until the urging force of the urging member 65 and the arm pressing portion 64c of the equalizer 64 are used to urge the lever side pressure receiving portion 62c to balance each other. Therefore, the front wheel brake 14 is not immediately actuated when the interlocking brake lever 40B is initially operated.

When the interlocking lever 40B is further pulled toward the grip 4b as shown in Fig. 25, and when the equalizer 64 is used to urge the lever side arm 62 to a greater force than the biasing member 65, the lever side arm 62 and the cylinder side The arms 63 rotate together with each other, and the cylinder side arms 63 The cylinder pressing portion 63a presses the pressure receiving portion 32a of the master cylinder 32B. In this way, the front wheel brake 14 is also actuated.

The equalizer 64 is positioned between the arm pressing portion 64c and the cable attaching portion 64b by the rotating support portion 64a supported by the interlocking lever 40B (see Fig. 21). One of the operating forces of the interlocking brake lever 40B is divided into a force input from the cable attachment portion 64b to the rear wheel brake 17 (the force at which the cable attachment portion 64b pulls the inner cable 11a) and a input from the arm pressing portion 64c to The force of the front wheel brake 14 (the force applied by the arm pressing portion 64c to the lever side arm 62). The division ratio is determined by the ratio of the distance from the center P2 of the rotation support portion 64a to the center P3 of the cable attachment portion 64b to the distance from the center P2 of the rotation support portion 64a to the arm pressing portion 64c. Therefore, the division ratio of the equalizer 64 is substantially constant throughout the rotation of the interlocking brake lever 40B.

Next, the operation of the brake device 10B will be described with reference to FIG. When the front rim lever 20 is pulled toward the grip 4a (see Fig. 3), the inner cable 21a of the transmission cable 21 pulls the tension portion 63e of the cylinder side arm 63 toward the vehicle width direction (direction W2 shown in the drawing). center. In this manner, the cylinder pressing portion 63a of the cylinder side arm 63 presses the pressure receiving portion 32a of the master cylinder 32B to actuate the front wheel brake 14 as shown in FIG. At this time, the pressed portion 63c of the cylinder side arm 63 is removed from the pressing portion 62a of the lever side arm 62, and the lever side arm 62 and the interlocking brake lever 40B are maintained at their respective positions.

Next, the operation of the brake device 10B will be described with reference to FIG. When the interlocking brake lever 40B is pulled to the grip 4b in a state where the inner cable 11a of the rear wheel brake cable 11 is not connected, the rotary support portion 64a of the equalizer 64 moves outward in the vehicle width direction. At this time, the equalizer 64 does not need to resist the arm pressing portion 64c from the rod side. The lever side of the arm 62 is rotated by the reaction force received by the pressed portion 62c. Therefore, the lever side arm 62 and the cylinder side arm 63 maintain their positions. In this manner, it is possible to prevent only the front wheel brake 14 from being actuated in the case where the interlocking brake lever 40B is operated when the inner cable 11a of the rear wheel brake cable 11 is not connected.

Next, the operation of the brake device 10B will be described with reference to FIG. When the interlocking brake lever 40B is pulled to the grip 4b in the case where the oil leaks from the hydraulic path 12, as in the case shown in Fig. 24, the equalizer 64 is biased toward the lever side arm 62 at the arm pressing portion 64c of the equalizer 64. The rear wheel brake cable 11 is only pulled before the force applied by the rod side pressed portion 62c and the urging force of the urging member 65 are balanced with each other. Subsequently, when the interlocking lever 40B is further pulled toward the grip 4b, the reaction force received by the arm pressing portion 64c of the equalizer 64 from the rod side pressure receiving portion 62c of the lever side arm 62 cannot become larger than the biasing member 65. Driven or higher. Therefore, the equalizer 64 is pulled by the rear wheel brake cable 11 to rotate. Then, as shown in Fig. 28, the arm pressing portion 64c of the equalizer 64 becomes in contact with the stopper 40i previously provided in front of the arm pressing portion 64c, thereby restricting further rotation of the equalizer 64. Therefore, the equalizer 64 pulls the rear wheel brake cable 11 further outward in the vehicle width direction, allowing the rear wheel brake 17 to further apply a braking force.

In the above-described brake device 10B, the equalizer 64 is used as a member for inputting an operation force of the interlocking brake lever 40B to the rear wheel brake 17 and the front wheel brake 14. The equalizer 64 divides the operating force of one of the linked brake levers 40B into a force input to the rear wheel brake 17 and a force input to the front wheel brake 14, the division ratio being from the center of the rotary support portion 64a of the equalizer 64 to The distance of the arm pressing portion 64c and the distance to the cable attachment portion 64b are determined. therefore, Even in the case where the inner cable 11a becomes slightly lengthened, for example, due to aging, the division ratio of the operating force of one of the interlocking brake levers 40B is not affected by the aging phenomenon of the inner cable 11a, so that the initial ratio is maintained.

In the above-described brake devices 10, 10A and 10B, the operation of the front wheel brake lever 20 by the knight is transmitted from the transmission cable 21 to the interlocking brake lever 40. However, the knight's operation on the front wheel brake lever 20 can be transmitted to the interlocking brake lever 40 by one lever.

Figure 29 is a schematic view of a brake device 10C according to this embodiment. Figure 30 is a cross-sectional view taken along line A-A of Figure 29. Figure 31 is a cross-sectional view taken along line B-B of Figure 29. Figure 32 is a cross-sectional view taken along line C-C of Figure 29. In the drawings, parts similar to those described above will be given similar reference numerals and will not be described again.

In the brake device 10C, as shown in Fig. 29, the aforementioned interlocking lever 40 is provided on the left handlebar 4, and a front wheel lever 20C is provided on the right handlebar 4. The brake device 10C includes a lever 51 as an operating force transmitting member that transmits the operation of the front wheel brake lever 20C to the front wheel brake actuating mechanism 30. The rod 51 is made of a rigid material such as metal. The rod 51 can be straight or can be slightly curved in an intermediate portion. The rod may be covered by a covering for covering the front of the vehicle body or may be placed behind a meter such as a speedometer so as not to be exposed to the outside.

The rod 51 is arranged to extend from one of the handlebars 4 to the other. One end of the rod 51 is coupled to the tension portion 31e of the arm 31, and unlike the aforementioned transmission cable 21, the relative movement between the rod 51 and the tension portion 31e is restricted.

Specifically, as shown in FIG. 30, one is used for the end and the tension of the coupling rod 51. A coupler 52 of portion 31e is provided at the end of the rod 51. The coupler 52 includes a base portion 52a and a pair of plates 52b, 52b extending perpendicularly from the base portion 52a. The rod 51 passes through a hole 52c formed in the base 52a. An engaging portion 51a having a diameter larger than the hole 52c is formed at the end of the rod 51. The joint portion 51a is provided in the coupler 52, and is held by the base portion 52a and the projecting portions 52d, 52d formed by the inward deformation of the pair of plates 52b, 52b. The tensioned portion 31e is disposed between the pair of plates 52b, 52b, and is coupled by a pin 53. That is, a hole having a size corresponding to the diameter of the pin 53 is formed in each of the pair of plates 52b, 52b and the tensioned portion 31e, and the pin 53 passes through the holes. An open end pin 54 is inserted into one end of the pin 53 to prevent the pin 53 from slipping off. In this manner, the rod 51 and the tension portion 31e are coupled together in a state in which relative movement therebetween is restricted. Therein, a hole having a size corresponding to the diameter of the pin 53 is formed in each of the pair of plates 52b, 52b. Alternatively, as shown above, an elongated hole for the transmission cable 21 of the brake device 10 is formed in the pulling portion 21c (see Fig. 14), and the hole of the pair 52b, 52b is replaced with an elongated hole.

As shown in FIG. 29, the front wheel brake lever 20C is rotatably supported by an attachment member 23C attached to the handlebar 4. That is, like the aforementioned front wheel brake lever 20, the support portion 20c is provided at the base of the front wheel brake lever 20C. The journal member 24 (e.g., a bolt) passes through a hole formed in the support portion 20c and a hole formed in the attachment member 23C, and the front wheel lever 20C is rotatable about the journal member 24.

In addition to the support portion 20c, a rod coupling portion 20d is provided at the base of the front wheel brake lever 20C. The rod 51 is restricted not only by its relative movement to the tension portion 31e of the arm 31 but also by its relative movement to the rod coupling portion 20d. It is coupled to the limit state. The lever 51 is provided with an adjustment mechanism 55 (see Fig. 31) for adjusting the distance between the rod coupling portion 20d and the tension portion 31e.

Specifically, as shown in FIG. 31, the other end of the rod 51 is coupled to the rod coupling portion 20d by a coupler 56. Like the aforementioned coupler 52, the coupler 56 includes a base portion 56a and a pair of plates 56b, 56b having a rod 51 passing through a hole 56c. The rod coupling portion 20d is disposed between the pair of plates 56b, 56b and is coupled by a pin 57. An open tail pin 58 is inserted into the distal end of the pin 57 to prevent the pin 57 from slipping off. A thread 51b is formed on the outer peripheral surface of the other end of the rod 51, and the base portion 56a is held between the two nuts 55a, 55b fitted to the thread 51b.

In this manner, the rod 51 is coupled to the rod coupling portion 20d by the coupling 56. The relative movement between the rod 51 and the rod coupling portion 20d is limited. Therefore, in the brake device 10C, when the interlocking lever 40 is operated to rotate toward the grip 4b, the movement of the interlocking lever 40 is transmitted to the front wheel lever 20C so that the front wheel lever 20C is also rotated toward the grip 4a. In this way, it is possible to enhance the operability of both of the linked brake lever 40 and the front wheel brake lever 20C in the case where the operation is successful. That is, when one of the front wheel brake levers 20C is started while the interlocking brake lever 40 is rotated toward the grip 4b, the movement of the front wheel brake lever 20C is immediately transmitted to the arm 31, so that the front wheel brake 14 can be applied to the front wheel brake The operating force of the lever 20C is actuated.

The size and position of the interlocking brake lever 40, the front wheel brake lever 20C, the arm 31, and other portions are set such that when the interlocking brake lever 40 is operated (when the interlocking brake lever 40 is moved to contact with the grip 4b), the front wheel The amount of movement of the brake lever 20C does not exceed the movable range of the front wheel brake lever 20C (the range from the position before the operation to the position where it comes into contact with the grip 4a). For example, the arm The size of the front wheel brake lever 20C and the front wheel brake lever 20C are set such that the distance from the center of rotation of the front wheel brake lever 20C (the center of the journal member 24) to the rod coupling portion 20d is greater than the center of rotation of the slave arm 31 (the center of the journal member 43) ) the distance to the tension portion 31e.

As shown in Figs. 29 and 31, the adjustment mechanism 55 is composed of two nuts 55a, 55b and a thread 51b, and the distance between the rod coupling portion 20d and the tension portion 31e is adjusted by rotating the thread 51b. That is, by rotating the thread 51b relative to the nut 55a, 55b to move the position of the nut 55a, 55b on the rod 51, the attachment position of the coupler 56 is moved in the longitudinal direction of the rod 51 to adjust the rod coupling. The distance between the connecting portion 20d and the tension portion 31e.

The front wheel brake lever 20C is configured to be rotated in a direction away from the grip 4a beyond the initial position of the front wheel brake lever 20C (see FIG. 29) in a state before the lever 51 is connected, that is, a position when the front wheel brake lever 20C is not operated ( Figure 29 shows the position of the front wheel brake lever 20C). The initial position of the front wheel brake lever 20C can be set at an appropriate position within the movable range of the front wheel brake lever 20C via the adjustment mechanism 55 adjusting the distance between the bar coupling portion 20d and the tension portion 31e. That is, the initial position of the grip portion 20a of the front wheel brake lever 20C may be due to the rotation lever 51, the attachment position of the movement coupling 56 on the rod 51, and the between the enlarged rod coupling portion 20d and the tension portion 31e. The distance is brought closer to the grip 4a. In contrast, the initial position of the grip portion 20a can be brought away from the grip 4a by reducing the distance between the rod coupling portion 20d and the tension portion 31e.

In some cases, the attachment position of the attachment member 23C on the handlebar 4 may be misaligned due to manufacturing tolerances or the like, and thus the initial position of the front wheel brake lever 20C may be too close or too far from the grip 4a. Also, in these cases, The initial position of the grip portion 20a can be appropriately set by adjusting the distance between the rod coupling portion 20d and the tension portion 31e.

As shown in Fig. 32, the brake device 10C is provided with a spring 29 for pushing the front wheel lever 20C in the direction of the pull rod 51. In the example, a spring retaining portion 23a is provided at a position where the attachment member 23C faces the base of the front rim lever 20C. One end of the spring 29 is fitted in a recess 23b formed in the spring holding portion 23a, and the other end is fitted in a recess 20e formed in the base of the front rim lever 20C. The spring 29 is a compression spring and exerts a force in a direction in which the base of the front wheel brake lever 20C and the spring holding portion 23a are separated from each other. The spring 29 prevents the front wheel brake lever 20C from swaying to make a sound.

In the above-described brake device 10C, the lever 51 is regarded as an operation force transmission member. Therefore, it is possible to further reduce the transmission loss of an operating force in a transmission path from the front rim brake lever to the front wheel brake actuation mechanism. Since the rod does not become longer than the cable over time, the user does not need to perform the length adjustment work. Therefore, it is possible to prevent the user from making improper adjustments.
