JP 2009-202650 A

  In such a motorcycle, when a brake lock mechanism that keeps the vehicle in a stopped state is adopted, it is desirable to operate the brake lock mechanism with a braking force applied only to the rear wheel brake.

  However, since the brake lock mechanism interposes a brake interlocking device, when a braking force is applied to the rear wheel brake, the front wheel brake is also in a braking state. When the brake lock mechanism is operated in this state, the rear mechanical brake can be maintained in the braking state, but the front hydraulic brake is also maintained in the braking state, and the hydraulic pressure is maintained in a high state. Become.

  Therefore, it is necessary to use high-load compatible pipes, joints, etc., and the entire brake system tends to increase in size and cost.

  On the other hand, a brake lock operation element is provided separately from the interlock operation element for braking the rear wheel brake, and a transmission member such as a wire for transmitting the brake lock operation is used from the brake lock operation element to the rear mechanical brake. Is also possible.

  However, in this case, the total length of the transmission member is increased, the wiring length is increased, and the number of work steps is increased. Further, since the two transmission members act on the brake arm of the rear mechanical brake, the brake arm is increased in size.

  Even if an interlocking device capable of interlocking a hydraulic brake and a mechanical brake is provided, the present invention keeps the rear mechanical brake in the braking state when the brake is locked while suppressing an increase in the transmission member as much as possible. It is an object of the present invention to provide a vehicular brake lock device capable of preventing a hydraulic pressure from being generated in a hydraulic brake and a saddle riding type vehicle including the same.

  The invention according to claim 1 is an interlock device that applies a braking force to a rear mechanical brake and a front hydraulic brake in accordance with an operation of the interlock operator, and a brake lock that can hold the interlock operator in a predetermined operation state. A brake block device for a vehicle, comprising: a cylinder block having a master cylinder that generates hydraulic pressure for applying a braking force to the front hydraulic brake in response to being pressed; A pressing arm having a contact portion on one end side, a pressing portion on the other end side, and having a first shaft at an intermediate portion between both ends, the cylinder block being interposed via the first shaft The pressing portion is urged and attached so that the abutting portion comes into contact with the cylinder block by the urging force of the urging member and is rotated against the urging force. Part A pressing arm that presses the master cylinder, and is attached to the other end side of the pressing arm via a second shaft so as to be rotatable, and an intermediate portion between both ends having the second shaft as one end side. A first transmission member extending from the interlocking operation element, and an equalizer connected to the second transmission member extending from the rear mechanical brake on the other end side, and the brake lock operation element The other end portion of the third transmission member whose one end portion is connected to the one end side of the pressing arm is connected, and the equalizer is pulled through the first transmission member by the operation of the interlocking operation element. Thus, the equalizer rotates around the second axis to apply a braking force to the rear mechanical brake via the second transmission member, and further, the pressing against the urging force of the urging member The arm is When the brake lock operating element is operated after turning around the axis of the front hydraulic brake and applying a braking force to the front hydraulic brake, the pressing arm moves toward the initial position via the third transmission member. By being pulled, the pressing of the master cylinder is released, and the interlocking operation element is held in a locked state.

  In addition to the structure of Claim 1, in the invention of Claim 2, the said press arm has a 1st long hole in the said one end side, and the said one end part of the said 3rd transmission member is the said It is connected movably along the first long hole.

  According to a third aspect of the invention, in addition to the configuration of the first aspect, the brake lock operator has a second elongated hole, and the other end of the third transmission member is the first It is characterized by being connected movably along the two long holes.

  According to a fourth aspect of the invention, in addition to the configuration of the third aspect, the urging member is provided on the brake lock operating element, and the other end of the third transmission member is connected to the first transmission member. It is urging | biasing in the direction away from the said press arm along 2 long holes.

  In the invention according to claim 5, in addition to the structure according to any one of claims 1 to 4, the interlock operation element and the brake lock operation element have different rotation centers on the handles. Supported, the interlock operator has an engaging portion, the brake lock operator has a locking portion, and the engaging portion is locked to the locking portion, thereby The locked state is maintained.

  In a sixth aspect of the invention, in the saddle riding type vehicle including the vehicle brake lock device according to any one of the first to fourth aspects, the head pipe and the head pipe extend downward and rearward. A main frame extending rearward from the lower end, and the interlocking device is provided in the vicinity of the head pipe.

  According to the first aspect of the present invention, when the brake lock operator is operated in the operation state of the interlocking operator, the pressing arm is returned to the initial position. For this reason, the master cylinder is not pressed, and no braking force is generated in the front hydraulic brake. On the other hand, since the operation state of the interlocking operation element is held by the brake lock operation element, a braking force is generated in the rear mechanical brake via the equalizer and the second transmission member, and the brake lock state is established.

  And even if it has an interlocking device that gives the braking force to the rear mechanical brake and the front hydraulic brake, no hydraulic pressure is generated when the brake is locked, so there is no need to use piping or fittings that can handle high loads. Thus, it is possible to reduce the size and cost of the brake system.

  Moreover, since it is sufficient that the transmission member for brake lock extends from the brake lock operator to the interlocking device, the transmission member can be shortened, and the wiring length can be shortened to suppress an increase in work man-hours. Further, since only one second transmission member is connected to the rear wheel brake arm, it is possible to suppress an increase in the size of the rear wheel brake arm.

  According to the second aspect of the invention, since the first elongated hole is formed in the pressing arm, even if the pressing arm rotates, the one end portion of the third transmission member becomes the first elongated hole. The third transmission member and the brake lock operating element are not activated only by moving along the path. Therefore, it becomes possible to improve the operation feeling.

  According to the invention which concerns on Claim 3, even if the 3rd transmission member is pulled by rotation of a press arm by forming a 2nd long hole in a brake lock operation element, the other end part is the 2nd. It only moves along the long hole, and the brake lock operator does not operate. Therefore, it is possible to prevent the passenger from feeling uncomfortable.

  According to the invention which concerns on Claim 4, since the urging | biasing member is provided not on the interlocking device but on the brake lock operator side, it becomes possible to make the interlocking device compact.

  According to the invention which concerns on Claim 5, since a brake lock mechanism is comprised by simple structure, cost can be reduced.

  According to the sixth aspect of the present invention, there is provided the vehicle brake lock device that keeps the mechanical brake in the braking state when the brake is locked and prevents the hydraulic brake from generating the hydraulic pressure while suppressing the increase of the transmission member as much as possible. A riding vehicle can be provided.

Next, the operation of the brake lock device 60 will be described with reference to FIGS.
FIG. 8A is a plan view showing an inoperative state of the interlocking operation element and the brake lock operation element. FIG. 8B is a front view of the interlocking device in that state. Fig.9 (a) is a top view which shows the operating state of an interlocking operation element. FIG. 9B is a front view of the interlocking device in that state. FIG. 10A is a plan view showing a state in which the interlocking operator is further operated from the state shown in FIG. FIG. 10B is a front view of the interlocking device in that state. Fig.11 (a) is a top view which shows the operating state of a brake lock operation element. FIG.11 (b) is a front view of the interlocking device in the state.

As shown in FIG. 8A, when both the interlocking operation element 62 and the brake lock operation element 67 are in the inoperative state, the interlocking device 70 is in the initial state as shown in FIG. 8B.
That is, in the interlocking rotation lever 81, the contact portion 83 is in contact with the contact surface 71 a of the cylinder block 71 due to the biasing force of the delay spring 85. The knocker 91 abuts against the abutting surface 71 a of the cylinder block 71 at the stopper portion 92 by the urging force of the return spring 75 of the unit-side master cylinder 73. The equalizer 100 is in contact with the stopper portion 76 of the cylinder block 71.

When the interlocking operation element 62 is operated and pulled as shown by a solid line in FIG. 9A, the interlocking device 70 is operated as shown in FIG. 9B.
That is, when the operator-side transmission member 65 is pulled as indicated by an arrow M1, the equalizer 100 rotates around the second rotation shaft 86 as indicated by an arrow E1. By the rotation of the equalizer 100, the brake-side transmission member 66 is pulled as shown by an arrow B1, so that a braking force is applied to the rear mechanical brake 61 (see FIG. 2).

Such a brake operation of the rear mechanical brake 61 gradually and strongly acts until the force M1 for pulling up the equalizer 100 exceeds the urging force D of the delay spring 85.
That is, while the force M1 for pulling up the equalizer 100 is lower than the biasing force D of the delay spring 85, the interlocking rotation lever 81 and the knocker 91 are maintained in the initial state. Therefore, the front hydraulic brake 51 (see FIG. 2) is held in a non-operating state.

When the interlocking operator 62 is further operated and further pulled as shown by the solid line from the position indicated by the chain line in FIG. 10A, the interlocking device 70 is operated as shown in FIG. 10B. .
That is, the operating element side transmission member 65 is pulled as indicated by an arrow M2. This pulling force is greater than the biasing force D of the delay spring 85. Therefore, the interlocking rotation lever 81 rotates around the first rotation shaft 82 as shown by the arrow C <b> 1 against the urging force of the delay spring 85. When the contact portion 93 of the knocker 91 is pushed by the contact portion 83 of the interlocking rotation lever 81, the knocker 91 resists the urging force of the return spring 75 of the unit-side master cylinder 73 and the first rotation shaft. Rotate around 82 as indicated by arrow N1.

  When the knocker 91 rotates as indicated by the arrow N1, the pressing portion 95 of the knocker 91 presses the piston 74 of the unit-side master cylinder 73 to operate the unit-side master cylinder 73. When the unit-side master cylinder 73 supplies oil from the unit-side hydraulic pipe 64 to the front hydraulic brake 51, a braking force is applied to the front hydraulic brake 51 (see FIG. 2).

  In the case of a normal brake operation, when the interlocking operation element 62 is returned in the operating state of the rear mechanical brake 61 and the front hydraulic brake 51, the interlocking device 70 is shown in FIG. Return to the initial state. As a result, both the rear mechanical brake 61 and the front hydraulic brake 51 return to the non-operating state.

On the other hand, in the case of a brake lock operation, the brake lock operator 67 is operated in a state where the interlocking operator 62 is pulled as shown by a solid line in FIG. It is pulled as shown in (a). Thereby, the interlocking device 70 is operated as shown in FIG.
That is, the brake lock transmission member 68 is pulled as shown by the arrow L1. Then, the knocker 91 is returned to the initial state by this pulling force. As a result, the pressing portion 95 of the knocker 91 does not press the piston 74, the unit-side master cylinder 73 becomes inoperative, and the front hydraulic brake 51 is released.

When the contact portion 83 of the interlocking rotation lever 81 is pushed by the contact portion 93 of the knocker 91, the interlocking rotation lever 81 rotates together with the knocker 91 around the first rotation shaft 82 as shown by an arrow C2. To return to the initial state. At this time, the equalizer 100 is pulled down somewhat as indicated by an arrow M3. In response to this, the interlocking operator 62 is somewhat returned.
Specifically, the interlocking operator 62 is returned from the position indicated by the chain line to the position indicated by the solid line in FIG. Then, the engaging part (recessed part) 62b of the interlocking operation element 62 is engaged with the engaging part (protrusion) 67b of the brake lock operation element 67, so that the interlocking operation element 62 is held in the locked state.

  That is, the interlocking operator 62 is rotatably supported by the left handle holder 26L via the support shaft 62a. The brake lock operator 67 is rotatably supported by the left handle holder 26L via a support shaft 67a.
