　本発明は、鞍乗り型車両の連動ブレーキ装置に関する。 The present invention relates to an interlocking brake device for a saddle-riding vehicle.
　従来、鞍乗り型車両の後輪に付与される制動力を前輪に分配する連動ブレーキ装置が知られている。連動ブレーキ装置は、イコライザ（操作力分配リンク）を備える。
　例えば、特許文献１では、イコライザをブレーキペダル（後ブレーキ操作子）の周辺に配置している。
　一方、特許文献２では、イコライザを後輪の車軸の後方に配置している。 Conventionally, an interlocking braking device that distributes the braking force applied to the rear wheels of a saddle-riding vehicle to the front wheels has been known. The interlocking brake device includes an equalizer (operating force distribution link).
For example, in Patent Document 1, the equalizer is arranged around the brake pedal (rear brake operator).
On the other hand, in Patent Document 2, the equalizer is arranged behind the axle of the rear wheel.

　しかし、特許文献１のようにイコライザをブレーキペダルの周辺に配置すると、ブレーキペダル周辺の部品配置が複雑になる。これにより、車両が車幅方向に肥大化する可能性がある。
　一方、特許文献２のようにイコライザを後輪の車軸の後方に配置すると、部品点数が多く且つ複雑な構造となる。これにより、後輪周辺の外観性が低下するとともに、コストが高くなる可能性がある。 However, if the equalizer is arranged around the brake pedal as in Patent Document 1, the arrangement of parts around the brake pedal becomes complicated. As a result, the vehicle may become bloated in the vehicle width direction.
On the other hand, if the equalizer is arranged behind the axle of the rear wheel as in Patent Document 2, the number of parts is large and the structure becomes complicated. As a result, the appearance around the rear wheels may be deteriorated and the cost may be increased.
　そこで本発明は、後ブレーキ操作子の周辺を簡素化するとともに、後輪周辺の外観性を向上し、かつ、低コスト化を図ることを目的とする。 Therefore, an object of the present invention is to simplify the periphery of the rear brake operator, improve the appearance around the rear wheel, and reduce the cost.
本発明の一態様の鞍乗り型車両の連動ブレーキ装置は、鞍乗り型車両（１）の前輪（１２）に制動力を付与する前ブレーキ機構（２０）と、ブレーキアーム（３１）を有し、前記ブレーキアーム（３１）の回動操作に応じて後輪（１３）に制動力を付与する後ブレーキ機構（３０）と、前記後輪（１３）の車軸（１５）と、前記後ブレーキ機構（３０）を操作するための後ブレーキ操作子（４０）と、車体側に固定されたブレーキパネル（５０）と、前記ブレーキパネル（５０）に回動可能に支持されるとともに、回動中心（Ｃ３）から離間した部位が前記前ブレーキ機構（２０）の操作入力部（２１）に連動可能に接続された反転リンク（６０）と、前記反転リンク（６０）の前記操作入力部（２１）との接続部とは反対側の端部に一端が回動可能に支持され、前記ブレーキアーム（３１）の回動中心（Ｃ２）から離間した部位に他端が連動可能に接続されたイコライザ（６９）と、前記イコライザ（６９）の前記一端から離間した部位と前記後ブレーキ操作子（４０）とを連動可能に連結するブレーキロッド（７０）と、を備え、前記イコライザ（６９）は、前記ブレーキアーム（３１）の前方に配置され、前記イコライザ（６９）の少なくとも一部は、側面視で前記ブレーキパネル（５０）と重なる。
　この構成によれば、イコライザを後ブレーキ操作子の周辺に配置する場合と比較して、後ブレーキ操作子の周辺が簡素化する。加えて、イコライザを後輪の車軸の後方に配置する場合と比較して、部品点数を削減することができる。加えて、イコライザを後輪の車軸の後方に配置する場合と比較して、ブレーキロッドの長さを短くすることができる。したがって、後ブレーキ操作子の周辺を簡素化するとともに、後輪周辺の外観性を向上し、かつ、低コスト化を図ることができる。 The interlocking braking device for a saddle-riding vehicle according to one aspect of the present invention has a front braking mechanism (20) for applying a braking force to the front wheels (12) of the saddle-riding vehicle (1) and a brake arm (31). A rear brake mechanism (30) that applies a braking force to the rear wheels (13) in response to a rotation operation of the brake arm (31), an axle (15) of the rear wheels (13), and the rear brake mechanism. The rear brake operator (40) for operating (30), the brake panel (50) fixed to the vehicle body side, and the brake panel (50) are rotatably supported and the center of rotation (30). A reversing link (60) in which a portion separated from C3) is interlocked with an operation input unit (21) of the front brake mechanism (20), and the operation input unit (21) of the reversing link (60). An equalizer (69) in which one end is rotatably supported at the end opposite to the connection portion of the brake arm (31) and the other end is interlocked with a portion separated from the rotation center (C2) of the brake arm (31). ), A brake rod (70) for interlocking a portion of the equalizer (69) separated from the one end and the rear brake operator (40), and the equalizer (69) is the brake. Arranged in front of the arm (31), at least a portion of the equalizer (69) overlaps the brake panel (50) in side view.
According to this configuration, the periphery of the rear brake operator is simplified as compared with the case where the equalizer is arranged around the rear brake operator. In addition, the number of parts can be reduced as compared with the case where the equalizer is arranged behind the axle of the rear wheel. In addition, the length of the brake rod can be shortened as compared with the case where the equalizer is arranged behind the axle of the rear wheel. Therefore, the periphery of the rear brake operator can be simplified, the appearance around the rear wheel can be improved, and the cost can be reduced.
　本発明の一態様において、前記イコライザ（６９）は、前記車軸（１５）の前方に配置され、前記ブレーキアーム（３１）は、前記車軸（１５）の後方に配置されてもよい。
　この構成によれば、イコライザとブレーキアームとが干渉しないレイアウトを容易に実現することができる。加えて、側面視でイコライザとブレーキアームとが重ならないため、車幅方向外側への張り出しを抑えることができる。 In one aspect of the present invention, the equalizer (69) may be arranged in front of the axle (15) and the brake arm (31) may be arranged behind the axle (15).
According to this configuration, it is possible to easily realize a layout in which the equalizer and the brake arm do not interfere with each other. In addition, since the equalizer and the brake arm do not overlap in the side view, it is possible to suppress the protrusion to the outside in the vehicle width direction.
　本発明の一態様において、前記反転リンク（６０）は、前記ブレーキアーム（３１）の前方に配置されるとともに、側面視で前記ブレーキパネル（５０）と重なってもよい。
　この構成によれば、反転リンクもイコライザと同様に側面視でブレーキパネルと重なるため、後輪周辺の外観性が更に向上する。 In one aspect of the present invention, the reversing link (60) may be arranged in front of the brake arm (31) and may overlap the brake panel (50) in a side view.
According to this configuration, the reversing link also overlaps with the brake panel in a side view like the equalizer, so that the appearance around the rear wheels is further improved.
　本発明の一態様において、前記ブレーキロッド（７０）は、前記イコライザ（６９）に対して着脱可能であってもよい。
　この構成によれば、後輪の脱着が簡単になるため、メンテナンス性が向上する。 In one aspect of the present invention, the brake rod (70) may be detachable from the equalizer (69).
According to this configuration, the rear wheels can be easily attached and detached, so that maintainability is improved.
　本発明の一態様において、鞍乗り型車両の連動ブレーキ装置は、前記車軸（１５）の上方に配置される前ブレーキケーブル（２６）を更に備え、前記ブレーキロッド（７０）は、前記車軸（１５）の下方に配置されてもよい。
　この構成によれば、前ブレーキケーブルとブレーキロッドとが干渉しないレイアウトを容易に実現することができる。 In one aspect of the present invention, the interlocking brake device for a saddle-mounted vehicle further includes a front brake cable (26) arranged above the axle (15), and the brake rod (70) is the axle (15). ) May be placed below.

The motorcycle 1 includes an interlocking braking device 2 that distributes the braking force applied to the rear wheels 13 to the front wheels 12. The interlocking brake device 2 operates the front brake mechanism 20 that applies braking force to the front wheels 12, the rear braking mechanism 30 that applies braking force to the rear wheels 13, the axle 15 of the rear wheels 13, and the rear braking mechanism 30. Brake pedal 40 (rear brake operator) for this purpose, a brake panel 50 fixed to the vehicle body side, a reversing link 60 rotatably supported by the brake panel 50, and an equalizer 69 connected to the reversing link 60. , The brake rod 70 that enables the equalizer 69 and the brake pedal 40 to be interlocked, the adjuster 80 for adjusting the relative positions of the equalizer 69 and the rear brake arm 31, and the load input from the equalizer 69 to the reversing link 60 are threshold values. It is provided with a delay spring 25 (elastic member) that restricts the rotation of the reversing link 60 until it exceeds the above, and a front brake cable 26 that is arranged above the axle 15.
　前ブレーキ機構２０は、基本的に、前ブレーキ操作子であるブレーキレバー（不図示）によって操作される。後ブレーキ機構３０は、後ブレーキ操作子であるブレーキペダル４０によって操作される。連動ブレーキ装置２は、ブレーキペダル４０に入力された操作荷重が所定の値（閾値）を越えた場合、操作荷重の一部を前ブレーキ機構２０にも作用させる。 The front brake mechanism 20 is basically operated by a brake lever (not shown) which is a front brake operator. The rear brake mechanism 30 is operated by a brake pedal 40 which is a rear brake operator. When the operating load input to the brake pedal 40 exceeds a predetermined value (threshold value), the interlocking brake device 2 also applies a part of the operating load to the front brake mechanism 20.
　前ブレーキ機構２０は、ドラム式ブレーキによって構成されている。前ブレーキ機構２０は、前輪１２と一体に回転するブレーキドラム（不図示）と、前輪１２の制動時にブレーキドラムの内周面に圧接されるブレーキシュー（不図示）と、ブレーキシューをブレーキドラムの内周面に圧接させる方向に押し動かすためのカム（不図示）と、カムを操作するための前ブレーキアーム２１と、を備える。ブレーキドラム、ブレーキシュー及びカム等の部品は、ブレーキハウジング２２の内部に配置されている。 The front brake mechanism 20 is composed of a drum type brake. The front brake mechanism 20 has a brake drum (not shown) that rotates integrally with the front wheel 12, a brake shoe (not shown) that is pressed against the inner peripheral surface of the brake drum when braking the front wheel 12, and a brake shoe of the brake drum.

　前ブレーキアーム２１は、ブレーキハウジング２２の車幅方向外側に配置されている。前ブレーキアーム２１は、前ブレーキ機構２０の操作入力部である。前ブレーキアーム２１は、操作力をうけて一方向（前輪車軸を中心とする時計回り方向）に回動することにより、前ブレーキ機構２０に制動力を生じさせる。前ブレーキアーム２１は、不図示の操作ケーブルを介して操作ハンドル上のブレーキレバーに接続されている。 The front brake arm 21 is arranged outside the brake housing 22 in the vehicle width direction. The front brake arm 21 is an operation input unit of the front brake mechanism 20. The front brake arm 21 receives an operating force and rotates in one direction (clockwise with respect to the front wheel axle) to generate a braking force in the front brake mechanism 20. The front brake arm 21 is connected to the brake lever on the operation handle via an operation cable (not shown).
　後ブレーキ機構３０は、ドラム式ブレーキによって構成されている。後ブレーキ機構３０は、後輪１３と一体に回転するブレーキドラム（不図示）と、後輪１３の制動時にブレーキドラムの内周面に圧接されるブレーキシュー（不図示）と、ブレーキシューをブレーキドラムの内周面に圧接させる方向に押し動かすためのカム（不図示）と、カムを操作するための後ブレーキアーム３１（ブレーキアーム）と、を備える。ブレーキドラム、ブレーキシュー及びカム等の部品は、ブレーキパネル５０の内部に配置されている。 The rear brake mechanism 30 is composed of a drum type brake. The rear brake mechanism 30 brakes a brake drum (not shown) that rotates integrally with the rear wheel 13, a brake shoe (not shown) that is pressed against the inner peripheral surface of the brake drum when braking the rear wheel 13, and a brake shoe. A cam (not shown) for pushing and moving in a direction of pressure contact with the inner peripheral surface of the drum, and a rear brake arm 31 (brake arm) for operating the cam are provided. Parts such as the brake drum, the brake shoe and the cam are arranged inside the brake panel 50.
図２に示すように、後ブレーキアーム３１は、上下方向に延びている。後ブレーキアーム３１は、後ブレーキ機構３０の操作入力部である。後ブレーキアーム３１は、自身の上端部に回動中心Ｃ２を有する。後ブレーキアーム３１は、車軸１５の後方に配置されている。後ブレーキアーム３１の回動中心Ｃ２の上下高さは、車軸１５（車軸中心Ｃ１）の上下高さよりも低い。側面視で、後ブレーキアーム３１の回動中心Ｃ２は、車軸中心Ｃ１の後下方に配置されている。 As shown in FIG. 2, the rear brake arm 31 extends in the vertical direction. The rear brake arm 31 is an operation input unit of the rear brake mechanism 30. The rear brake arm 31 has a rotation center C2 at its upper end. The rear brake arm 31 is arranged behind the axle 15. The vertical height of the rotation center C2 of the rear brake arm 31 is lower than the vertical height of the axle 15 (axle center C1). From the side view, the rotation center C2 of the rear brake arm 31 is arranged rearward and downward of the axle center C1.
　図１に示すように、ブレーキペダル４０は、車体側部に回動自在に支持されるピボット軸４１から前方に延びる操作アーム４２と、ピボット軸４１から上方に延びる作動アーム４３と、を備える。操作アーム４２の先端側上面は、ブレーキ操作時に運転者によって踏み込まれるようになっている。図中において、符号４５はブレーキペダル４０を初期位置に付勢するリターンスプリング、符号４６はブレーキペダル４０の回動変位を規制するストッパをそれぞれ示す。 As shown in FIG. 1, the brake pedal 40 includes an operation arm 42 extending forward from the pivot shaft 41 rotatably supported on the side of the vehicle body, and an operating arm 43 extending upward from the pivot shaft 41. The upper surface of the operation arm 42 on the tip end side is stepped on by the driver when the brake is operated. In the figure, reference numeral 45 indicates a return spring that urges the brake pedal 40 to the initial position, and reference numeral 46 indicates a stopper that regulates the rotational displacement of the brake pedal 40.
ブレーキパネル５０は、スイングアーム１１の後端部に連結されている。図２の側面視で、ブレーキパネル５０は、円形状のパネル本体５１と、パネル本体５１の上部から前方に延びる前方延在部５２と、を備える。例えば、パネル本体５１及び前方延在部５２は、同一の部材（例えば金属）で一体に形成されている。図中において、符号５３はディレイスプリング２５を係止するための係止爪、符号５４は反転リンク６０の過度の回動（回動中心Ｃ３の反時計回りの過度の回動）を規制するストッパをそれぞれ示す。係止爪５３は、前方延在部５２の前端部から下方に突出している。ストッパ５４は、車軸１５の上方位置で上方に凸の弧状をなしている。 The brake panel 50 is connected to the rear end of the swing arm 11. In the side view of FIG. 2, the brake panel 50 includes a circular panel main body 51 and a front extending portion 52 extending forward from the upper part of the panel main body 51. For example, the panel body 51 and the front extending portion 52 are integrally formed of the same member (for example, metal). In the figure, reference numeral 53 is a locking claw for locking the delay spring 25, and reference numeral 54 is a stopper for restricting excessive rotation of the reversing link 60 (excessive rotation of the rotation center C3 counterclockwise). Are shown respectively. The locking claw 53 projects downward from the front end portion of the front extending portion 52. The stopper 54 has an upwardly convex arc shape at a position above the axle 15.
図３に示すように、ブレーキパネル５０は、車幅方向に延びる支軸５６を挿通可能に車幅方向に開口する貫通孔５５を有する。図中において、符号５７は支軸５６の一端部（車幅方向内端部）に係合する抜け止めクリップ、符号５８は支軸５６の他端部（車幅方向外端部）に取り付けられるＯリングをそれぞれ示す。 As shown in FIG. 3, the brake panel 50 has a through hole 55 that opens in the vehicle width direction so that a support shaft 56 extending in the vehicle width direction can be inserted. In the figure, reference numeral 57 is attached to a retaining clip that engages with one end (inner end in the vehicle width direction) of the support shaft 56, and reference numeral 58 is attached to the other end (outer end in the vehicle width direction) of the support shaft 56. Each O-ring is shown.
　反転リンク６０は、支軸５６を中心としてブレーキパネル５０に対して回動可能に支持されている。反転リンク６０は、回動中心Ｃ３から離間した部位が前ブレーキアーム２１（図１参照、前ブレーキ機構２０の操作入力部）に連動可能に接続されている。 The reversing link 60 is rotatably supported with respect to the brake panel 50 about the support shaft 56. The reversing link 60 is connected to the front brake arm 21 (see FIG. 1, the operation input portion of the front brake mechanism 20) so as to be interlocked with a portion separated from the rotation center C3.
　図２に示すように、支軸５６の上下高さは、車軸１５の上下高さと実質的に同じである。側面視で、支軸５６は、ブレーキパネル５０の前部の前後中央部に配置されている。側面視で、反転リンク６０は、ブレーキパネル５０のパネル本体５１と重なる。 As shown in FIG. 2, the vertical height of the support shaft 56 is substantially the same as the vertical height of the axle 15. From the side view, the support shaft 56 is arranged at the front-rear central portion of the front portion of the brake panel 50. From the side view, the reversing link 60 overlaps the panel body 51 of the brake panel 50.
　側面視で、反転リンク６０は、支軸５６と重なる部位から後上方へ湾曲して延びる湾曲延在部６１と、支軸５６と重なる部位から下方へ延びる下方延在部６２と、を備える。例えば、湾曲延在部６１及び下方延在部６２は、同一の部材（例えば金属）で一体に形成されている。 From a side view, the reversing link 60 includes a curved extending portion 61 extending rearwardly and upwardly from a portion overlapping the support shaft 56, and a downward extending portion 62 extending downward from the portion overlapping the support shaft 56. For example, the curved extending portion 61 and the downward extending portion 62 are integrally formed of the same member (for example, metal).
　例えば、反転リンク６０は、ブレーキパネル５０と同一の部材（例えば金属）で形成されることが好ましい。例えば、反転リンク６０は、ブレーキパネル５０と同一の金属光沢を有することが好ましい。この場合、側面視で反転リンク６０とブレーキパネル５０とが同化して見えるようになるため、外観性の向上に寄与する。 For example, the reversing link 60 is preferably formed of the same member (for example, metal) as the brake panel 50. For example, the reversing link 60 preferably has the same metallic luster as the brake panel 50. In this case, the reversing link 60 and the brake panel 50 appear to be assimilated when viewed from the side, which contributes to the improvement of the appearance.
　湾曲延在部６１の上端部は、前ブレーキケーブル２６の他端（後端）に接続されている。反転リンク６０は、前ブレーキケーブル２６を介して前ブレーキアーム２１（図１参照）に連動可能に接続されている。図中符号は、前ブレーキケーブル２６の一部（反転リンク６０寄りの部位）を案内するガイド片を示す。 The upper end of the curved extension portion 61 is connected to the other end (rear end) of the front brake cable 26. The reversing link 60 is interlockably connected to the front brake arm 21 (see FIG. 1) via the front brake cable 26. Reference numerals in the figure indicate a guide piece that guides a part of the front brake cable 26 (a portion near the reversing link 60).

A portion 66d and a second lower extending portion 66e extending downward from the lower end of the second lower inclined portion 66d are provided. The second connecting portion 66a, the second upper inclined portion 66b, the second upper extending portion 66c, the second lower inclined portion 66d, and the second lower extending portion 66e are integrally formed of the same member.

The second connecting portion 66a is connected to the first connecting portion 65a from the outside in the vehicle width direction. The second upper inclined portion 66b and the second upper extending portion 66c are separated from the first upper inclined portion 65b and the first upper extending portion 65c in the vehicle width direction, respectively. The second lower inclined portion 66d and the second lower extending portion 66e are separated from the first lower inclined portion 65d and the first lower extending portion 65e in the vehicle width direction, respectively.
　図２に示すように、反転リンク６０は、ディレイスプリング２５の一端が係止される係止孔６３を有する。係止孔６３は、反転リンク６０の厚み方向（車幅方向）に開口している。係止孔６３は、反転リンク６０の上端部と支軸５６の接続部との間に形成されている。図３に示すように、係止孔６３は、反転リンク６０の連結部６５ａ，６６ａにおける上傾斜部６５ｂ，６６ｂの近傍に形成されている。 As shown in FIG. 2, the reversing link 60 has a locking hole 63 in which one end of the delay spring 25 is locked. The locking hole 63 opens in the thickness direction (vehicle width direction) of the reversing link 60. The locking hole 63 is formed between the upper end portion of the reversing link 60 and the connecting portion of the support shaft 56. As shown in FIG. 3, the locking hole 63 is formed in the vicinity of the upward inclined portions 65b and 66b in the connecting portions 65a and 66a of the reversing link 60.
　イコライザ６９は、上下方向に延びる板部材である。イコライザ６９は、反転リンク６０の下端部（反転リンク６０の前ブレーキアーム２１との接続部とは反対側の端部）に上端（一端）が回動可能に支持されている。図２に示すように、イコライザ６９は、後ブレーキアーム３１の下端部（後ブレーキアーム３１の回動中心Ｃ２から離間した部位）に下端（他端）が連動可能に接続されている。イコライザ６９の下端は、前後方向に延びるアジャスタ８０を介して後ブレーキアーム３１の下端部に接続されている。 The equalizer 69 is a plate member extending in the vertical direction. The upper end (one end) of the equalizer 69 is rotatably supported by the lower end portion of the reversing link 60 (the end portion of the reversing link 60 opposite to the connection portion with the front brake arm 21). As shown in FIG. 2, the lower end (the other end) of the equalizer 69 is interlocked with the lower end portion of the rear brake arm 31 (a portion separated from the rotation center C2 of the rear brake arm 31). The lower end of the equalizer 69 is connected to the lower end of the rear brake arm 31 via an adjuster 80 extending in the front-rear direction.
　イコライザ６９は、後ブレーキアーム３１の前方に配置されている。イコライザ６９は、車軸１５の前方に配置されている。側面視で、イコライザ６９の上部は、ブレーキパネル５０の前下部と重なる。 The equalizer 69 is arranged in front of the rear brake arm 31. The equalizer 69 is arranged in front of the axle 15. From the side view, the upper part of the equalizer 69 overlaps the front lower part of the brake panel 50.
例えば、イコライザ６９は、ブレーキパネル５０と同一の部材（例えば金属）で形成されることが好ましい。例えば、イコライザ６９は、ブレーキパネル５０と同一の金属光沢を有することが好ましい。この場合、側面視でイコライザ６９とブレーキパネル５０とが同化して見えるようになるため、外観性の向上に寄与する。 For example, the equalizer 69 is preferably made of the same member (for example, metal) as the brake panel 50. For example, the equalizer 69 preferably has the same metallic luster as the brake panel 50. In this case, the equalizer 69 and the brake panel 50 appear to be assimilated when viewed from the side, which contributes to the improvement of the appearance.
　ブレーキロッド７０は、イコライザ６９の上下中央部（イコライザ６９の一端から離間した部位）とブレーキペダル４０（図１参照）とを連動可能に連結している。ブレーキロッド７０は、車軸１５の下方に配置されている。ブレーキロッド７０は、前後方向に延びている。ブレーキロッド７０の前端部は、作動アーム４３（図１参照）の上端部に回動可能に連結されている。ブレーキロッド７０の後端部は、イコライザ６９の上下中央部に回動可能に連結されている。 The brake rod 70 is interlockably connected to the upper and lower central portions of the equalizer 69 (a portion separated from one end of the equalizer 69) and the brake pedal 40 (see FIG. 1). The brake rod 70 is arranged below the axle 15. The brake rod 70 extends in the front-rear direction. The front end of the brake rod 70 is rotatably connected to the upper end of the actuating arm 43 (see FIG. 1). The rear end portion of the brake rod 70 is rotatably connected to the upper and lower central portions of the equalizer 69.
　ブレーキロッド７０の後端部は、イコライザ６９に対して着脱可能である。ブレーキロッド７０の後端部は、イコライザ６９の上下中央部を前側から囲うように後方を開放する断面Ｕ字状のブラケット７１の前面に連結されている。図３に示すように、ブラケット７１は、車幅方向に延びる係止ピン７２、係止ピン７２に係止される係止リング７３、および係止ピン７２の先端部に取り付けられる抜け止めクリップによってイコライザ６９に連結されている。例えば、係止ピン７２、係止リング７３及び抜け止めクリップ７４は、専用の工具によって分解可能である。係止ピン７２を抜け止めクリップ７４から抜くことにより、ブレーキロッド７０とイコライザ６９との結合を解除することができる。 The rear end of the brake rod 70 is removable from the equalizer 69. The rear end portion of the brake rod 70 is connected to the front surface of a bracket 71 having a U-shaped cross section that opens rearward so as to surround the upper and lower central portions of the equalizer 69 from the front side. As shown in FIG. 3, the bracket 71 is provided by a locking pin 72 extending in the vehicle width direction, a locking ring 73 locked to the locking pin 72, and a retaining clip attached to the tip of the locking pin 72. It is connected to the equalizer 69. For example, the locking pin 72, the locking ring 73, and the retaining clip 74 can be disassembled by a dedicated tool. By pulling out the locking pin 72 from the retaining clip 74, the connection between the brake rod 70 and the equalizer 69 can be released.
　図２に示すように、アジャスタ８０は、前後方向に延びるボルト８１（ロッド）と、ボルト８１に螺合するナット８２と、を備える。ボルト８１の前端部は、ブラケット８３を介してイコライザ６９の下端部に接続されている。ボルト８１の前端部は、車幅方向に延びる軸回りにイコライザ６９の下端部に対して回動可能とされている。後ブレーキアーム３１の下端部は、ボルト８１の一部（図では後端部）に接続されている。後ブレーキアーム３１の下端部は、不図示の付勢部材によってナット８２に向けて付勢されている。ナット８２をボルト８１の軸線回りに回転させることにより、ナット８２はボルト８１の軸線に沿って移動する。これにより、イコライザ６９の下端部及び後ブレーキアーム３１の下端部の相対位置が調整可能とされている。 As shown in FIG. 2, the adjuster 80 includes a bolt 81 (rod) extending in the front-rear direction and a nut 82 screwed into the bolt 81. The front end portion of the bolt 81 is connected to the lower end portion of the equalizer 69 via the bracket 83. The front end portion of the bolt 81 is rotatable with respect to the lower end portion of the equalizer 69 around an axis extending in the vehicle width direction. The lower end of the rear brake arm 31 is connected to a part of the bolt 81 (the rear end in the figure). The lower end of the rear brake arm 31 is urged toward the nut 82 by an urging member (not shown). By rotating the nut 82 around the axis of the bolt 81, the nut 82 moves along the axis of the bolt 81. As a result, the relative positions of the lower end of the equalizer 69 and the lower end of the rear brake arm 31 can be adjusted.
　ディレイスプリング２５は、常時、反転リンク６０を初期位置の方向（図２の初期状態）に付勢している。ディレイスプリング２５の一端は、反転リンク６０に係止されている。ディレイスプリング２５の他端は、ブレーキパネル５０の前方延在部５２の係止爪５３に係止されている。ディレイスプリング２５は、反転リンク６０の上端部を前方へ付勢している。 The delay spring 25 always urges the reversing link 60 in the direction of the initial position (initial state in FIG. 2). One end of the delay spring 25 is locked to the reversing link 60. The other end of the delay spring 25 is locked to the locking claw 53 of the front extending portion 52 of the brake panel 50. The delay spring 25 urges the upper end of the reversing link 60 forward.
　ディレイスプリング２５は、イコライザ６９から反転リンク６０に入力される荷重が閾値を超えるまで、反転リンク６０の回動を規制する。ディレイスプリング２５は、イコライザ６９から反転リンク６０に入力される荷重が閾値を越えた後に、反転リンク６０の図中反時計回り方向（支軸５６を中心とする反時計回り方向）の回動を許容する。 The delay spring 25 regulates the rotation of the reversing link 60 until the load input from the equalizer 69 to the reversing link 60 exceeds the threshold value. After the load input from the equalizer 69 to the reversing link 60 exceeds the threshold value, the delay spring 25 rotates the reversing link 60 in the counterclockwise direction (counterclockwise direction centered on the support shaft 56) in the figure. Tolerate.
　前ブレーキケーブル２６は、後ブレーキ機構３０の操作時にその操作力の一部を入力する連動用の操作ケーブルである。前ブレーキケーブル２６は、車軸１５の前上方に配置されている。前ブレーキケーブル２６は、前後方向に延びている。前ブレーキケーブル２６の前端（一端）は、前ブレーキアーム２１（図１参照）に接続されている。前ブレーキケーブル２６の後端（他端）は、反転リンク６０の上端部に接続されている。図３に示すように、前ブレーキケーブル２６の後端は、車幅方向に延びるピン２７を介して第一上延在部６５ｃ及び第二上延在部６６ｃに連結されている。 The front brake cable 26 is an interlocking operation cable that inputs a part of the operating force when operating the rear brake mechanism 30. The front brake cable 26 is arranged above the front of the axle 15. The front brake cable 26 extends in the front-rear direction. The front end (one end) of the front brake cable 26 is connected to the front brake arm 21 (see FIG. 1). The rear end (other end) of the front brake cable 26 is connected to the upper end of the reversing link 60. As shown in FIG. 3, the rear end of the front brake cable 26 is connected to the first upper extending portion 65c and the second upper extending portion 66c via a pin 27 extending in the vehicle width direction.
＜連動ブレーキ装置の動作＞
　ブレーキペダル４０が踏み込み操作されない初期状態では、反転リンク６０は、ディレイスプリング２５の付勢力を受けて図２の初期位置にある。反転リンク６０が初期位置にある場合、前ブレーキケーブル２６は引き込まれていないため、前ブレーキ機構２０には制動力が作用していない。 <Operation of interlocking brake device>
In the initial state in which the brake pedal 40 is not depressed, the reversing link 60 is in the initial position shown in FIG. 2 by receiving the urging force of the delay spring 25. When the reversing link 60 is in the initial position, the front brake cable 26 is not pulled in, so that no braking force is applied to the front brake mechanism 20.
　図２の状態からブレーキペダル４０が踏み込まれると、ブレーキペダル４０が図１中時計回り（ピボット軸４１を中心とする時計回り）に回動する。すると、ブレーキペダル４０の作動アーム４３の変位に伴って操作力（図４の矢印Ｖ１方向の力）がブレーキロッド７０を通してイコライザ６９に入力される。このとき、イコライザ６９に入力された操作力の一部は、反転リンク６０に伝達される。イコライザ６９に入力された操作力の残りの一部は、アジャスタ８０を介して後ブレーキアーム３１に伝達される。 When the brake pedal 40 is depressed from the state shown in FIG. 2, the brake pedal 40 rotates clockwise in FIG. 1 (clockwise around the pivot axis 41). Then, the operating force (force in the direction of arrow V1 in FIG. 4) is input to the equalizer 69 through the brake rod 70 with the displacement of the operating arm 43 of the brake pedal 40. At this time, a part of the operating force input to the equalizer 69 is transmitted to the inverting link 60. The remaining part of the operating force input to the equalizer 69 is transmitted to the rear brake arm 31 via the adjuster 80.
　ブレーキペダル４０が踏み込まれた初期の段階（図４の状態）では、イコライザ６９から反転リンク６０に入力される荷重が閾値（連動開始閾値）を超えない。そのため、反転リンク６０の回動は、ディレイスプリング２５によって規制されている。そのため、イコライザ６９の上端部側の変位が反転リンク６０によって規制されつつ、イコライザ６９の長手方向の中央部がブレーキロッド７０によって前方に引き込まれ、後ブレーキアーム３１が図４中反時計回り（回動中心Ｃ２回りの矢印Ｖ２方向）に回動する。その結果、後ブレーキ機構３０のみがブレーキペダル４０の踏み込み量に応じた制動力を発生する。すなわち、前ブレーキ機構２０は制動力を発生しない。 In the initial stage (state of FIG. 4) when the brake pedal 40 is depressed, the load input from the equalizer 69 to the reversing link 60 does not exceed the threshold value (interlocking start threshold value). Therefore, the rotation of the reversing link 60 is regulated by the delay spring 25. Therefore, while the displacement on the upper end side of the equalizer 69 is regulated by the reversing link 60, the central portion of the equalizer 69 in the longitudinal direction is pulled forward by the brake rod 70, and the rear brake arm 31 is rotated counterclockwise in FIG. It rotates in the direction of the arrow V2 around the center of motion C2). As a result, only the rear brake mechanism 30 generates a braking force according to the amount of depression of the brake pedal 40. That is, the front brake mechanism 20 does not generate a braking force.
　また、この状態からブレーキペダル４０の踏み込み量が増加すると、イコライザ６９から反転リンク６０に入力される荷重が閾値を超える。この場合、反転リンク６０がディレイスプリング２５の付勢力に抗して、図５中反時計回り（回動中心Ｃ３回りの矢印Ｖ３方向）に回動する。すると、反転リンク６０に連結された前ブレーキケーブル２６が引き込まれる。これにより、前ブレーキケーブル２６を介して前ブレーキ機構２０の前ブレーキアーム２１が回動する。この間、後ブレーキ機構３０の後ブレーキアーム３１もイコライザ６９を介して回動する。その結果、後ブレーキ機構３０及び前ブレーキ機構２０において、ブレーキペダル４０の踏み込み量に応じた制動力を発生する。 Further, when the amount of depression of the brake pedal 40 increases from this state, the load input from the equalizer 69 to the reversing link 60 exceeds the threshold value. In this case, the reversing link 60 rotates counterclockwise in FIG. 5 (in the direction of arrow V3 around the center of rotation C3) against the urging force of the delay spring 25. Then, the front brake cable 26 connected to the reversing link 60 is pulled in. As a result, the front brake arm 21 of the front brake mechanism 20 rotates via the front brake cable 26. During this time, the rear brake arm 31 of the rear brake mechanism 30 also rotates via the equalizer 69. As a result, the rear brake mechanism 30 and the front brake mechanism 20 generate a braking force according to the amount of depression of the brake pedal 40.
＜作用効果＞
以上説明したように、上記実施形態における自動二輪車１の連動ブレーキ装置２は、自動二輪車１の前輪１２に制動力を付与する前ブレーキ機構２０と、後ブレーキアーム３１を有し、後ブレーキアーム３１の回動操作に応じて後輪１３に制動力を付与する後ブレーキ機構３０と、後輪１３の車軸１５と、後ブレーキ機構３０を操作するためのブレーキペダル４０と、車体側に固定されたブレーキパネル５０と、後ブレーキパネル５０に回動可能に支持されるとともに、回動中心Ｃ３から離間した部位が前ブレーキ機構２０の前ブレーキアーム２１に連動可能に接続された反転リンク６０と、反転リンク６０の前ブレーキアーム２１との接続部とは反対側の端部に一端が回動可能に支持され、後ブレーキアーム３１の回動中心から離間した部位に他端が連動可能に接続されたイコライザ６９と、イコライザ６９の一端から離間した部位とブレーキペダル４０とを連動可能に連結するブレーキロッド７０と、を備え、イコライザ６９は、後ブレーキアーム３１の前方に配置され、イコライザ６９の上部は、側面視でブレーキパネル５０と重なる。
　本実施形態によれば、イコライザ６９をブレーキペダル４０の周辺に配置する場合と比較して、ブレーキペダル４０の周辺が簡素化する。加えて、イコライザ６９を後輪１３の車軸１５の後方に配置する場合と比較して、部品点数を削減することができる。加えて、イコライザ６９を後輪１３の車軸１５の後方に配置する場合と比較して、ブレーキロッド７０の長さを短くすることができる。したがって、ブレーキペダル４０の周辺を簡素化するとともに、後輪１３周辺の外観性を向上し、かつ、低コスト化を図ることができる。 <Effect>
