Definitions
- the present invention relates to a vehicle bracket that supports auxiliary equipment such as a brake reservoir (also referred to as a “brake reservoir tank”) and a clutch reservoir (also referred to as a “clutch reservoir tank”) disposed in an engine room of the vehicle, for example.
- auxiliary equipment such as a brake reservoir (also referred to as a “brake reservoir tank”) and a clutch reservoir (also referred to as a “clutch reservoir tank”) disposed in an engine room of the vehicle, for example.
- an auxiliary device that indirectly assists the traveling is attached to the inner wall surface of the engine room with a bolt via a bracket.
- the brake reservoir (reservoir tank) is generally disposed immediately below the hood as described in Patent Documents 1 and 2.
- the hood can protect the pedestrian when the vehicle collides with the pedestrian by jumping up the pedestrian with a front bumper and using the hood as a cushioning material. For this reason, the hood is thin and easily deformed and has a cushioning property so as to sufficiently absorb the impact force of the pedestrian at the time of collision.
- Patent Document 3 A tank mounting structure is known.
- FIG. 6 is an exploded perspective view showing a bracket, a support jig, and a brake fluid vacuum filling jig used when attaching a conventional brake reservoir to a vehicle body.
- FIG. 7 is a perspective view showing a state in which a lower support jig and a brake fluid vacuum filling jig are attached to a brake reservoir attached to a vehicle body with a conventional bracket.

Abstract
Description
また、ブラケット300は、衝突した際に歩行者を保護するために、金属製板材からなるブラケット本体310をL字状に折曲させて上側支持片301に弾性を持たせ、強度をやや低下させることによって、衝撃エネルギーを吸収する機能を向上させている。
このため、ブレーキフルード真空充填時に、下支え治具500を使用してブレーキフルード真空充填治具400を下から支えなければならないので、これに使用する加工工具の数や作業工数が多くなるので、充填作業の作業性が悪いという問題点があった。

車両用ブラケット3(以下、単に「ブラケット3」という)は、取り付ける被取付部の状態によって設置する向きが変化する。以下、便宜上、車両1の進行方向を「前」、後退方向を「後」、車幅方向を「左」、「右」として説明する。まず、ブラケット3を説明する前に、このブラケット3が取り付けられる車両1及び車体11について説明する。
図1に示すように、車両1は、車体11の前方部分にエンジンルーム12を有する自動車であり、そのエンジンルーム12内に、補機2を支持するブラケット3が取り付けられている。
なお、車両1は、エンジンルーム12を有する自動車であればよく、車両1の型式等は特に限定されない。つまり、車両1は、バスやトラックや作業車等であってもよい。以下、車体11の前方部分にエンジンルーム12を配置したボンネット形の乗用車を例に挙げてブラケット3を説明する。
図1に示すように、車体11は、自動車の骨格を形成する不図示の骨格フレームと、パネルボディと、から主に構成されている。この車体11には、車室Rの前方に、フード13によって上部開口部が開閉される前記エンジンルーム12が形成されている。
図1に示すように、エンジンルーム12は、エンジン(図示省略)を収納する空間であり、内壁12aと、フード13とを備えて中空状に形成されている。そのエンジンルーム12内には、エンジンを駆動させて車両1を走行させるのに必要な周辺機器である補機2が配置されている。
側壁12b,12bは、不図示の左右一対のサイドメンバ(図示省略)に固定された金属製パネル材によって形成されている。
隔壁12cは、前記左右のサイドメンバと、このサイドメンバに直交して配置されたクロスメンバ(図示省略)に固定された金属製パネル材からなる。
前記補機2は、エンジンを駆動させて車両1を走行させるのに必要な機器であればよく、その機器については、特に限定されない。補機2は、例えば、フットブレーキ用のブレーキリザーバ21やクラッチリザーバ22(図4参照)からなり、ブラケット3を介在してエンジンルーム12の内壁12aにボルト締めされる。
図1に示すように、ブレーキリザーバ21は、ブレーキに用いられるブレーキフルードを貯溜しておくためのタンクである。ブレーキリザーバ21は、樹脂製のタンク本体21aと、タンク本体21aの開口部21c(図2参照)を塞ぐキャップ21bと、から主に構成されている。ブレーキリザーバ21は、ブレーキフルードをその供給先であるブレーキのブレーキマスタシリンダ(図示省略)に供給するときに、エアの吸い込みを防止するために、エンジンルーム12内において、ブレーキマスタシリンダ(図示省略)より高い位置に配置されている。
下ケース21eには、前記取付片21fと、一端がマスタシリンダ(図示省略)に接続されたチューブ5(図1参照)の他端が接続されるチューブ接続部21iと、が形成されている。
鍔部21gは、開口部21cからブレーキリザーバ21内にブレーキフルードを注入するブレーキフルード真空充填治具4の連結部41が係止される部位である(図3参照)。
なお、ブレーキフルード真空充填治具4は、前記した従来のブレーキフルード真空充填治具400(図6及び図7参照)と同じ構造をしている。
図4に示すように、クラッチリザーバ22は、クラッチに用いられるクラッチフルードを貯溜しておくためのタンクである。クラッチリザーバ22は、樹脂製の第2タンク本体22aと、第2タンク本体22aの開口部(図示省略)を塞ぐ蓋部22bと、から主に構成されている。クラッチリザーバ22は、クラッチフルードをクラッチ装置のクラッチマスタシリンダ(図示省略)にスムーズに供給できるようにするために、クラッチマスタシリンダより高いエンジンルーム12内の上方部位に配置されている。
係合片22cは、第2タンク本体22aの側面に垂直に一体形成された四角形の厚板状のものからなる。
当接部22dは、係合片22cの上端部から第2タンク本体22aの側面に亘って水平に一体形成された平板状のものからなる。
図2に示すように、ブラケット3(車両用ブラケット)は、補機2を車体11に固定するための固定部材である。ブラケット3は、例えば、第1板部材31、第2板部材32、第3板部材33及び第4板部材34をそれぞれ所望形状にプレス加工した金属製板部材から構成されており、これらの4つの金属製板部材が溶接手段によって一体に溶接接合して形成されてなる。ブラケット3は、それぞれ後記する上側固定部3aと、下側固定部3bと、第1支持部3cと、第2支持部3dと、を有している。
なお、ブラケット3が取り付けられる部位は、エンジンルーム12内であればよく、以下、隔壁12c(内壁12a)に取り付けた場合を例に挙げて説明する。このブラケット3は、上側固定部3aと下側固定部3bとの二箇所を隔壁12c(車体11)にボルト締めして二点支持される。
図5に示すように、第1板部材31には、ブラケット3をエンジンルーム12の内壁12aに固定した際に、内壁12aに当接する第1当接面31aと、前記取付片21f(図2参照)が載置される座面31bと、内壁12aから離間した位置に配置される垂下部31cと、が形成されている。
垂下部31cは、座面31bの前側端部から下側に向かって折曲されて垂下した状態に形成された部位であり、前記第1当接面31a及び後記する第2当接面32aから前側方向に離間して配置されている。
固定孔31dは、ブラケット3を隔壁12cに取り付ける際の基準位置となる孔である。
図5に示すように、第2板部材32は、第1板部材31の前側端部に接合されて連結される板部材である。第2板部材32には、ブラケット3をエンジンルーム12の隔壁12cに固定した際に、隔壁12cに当接する第2当接面32aと、第2当接面32aから前方側に延設された腕部32bと、内壁12aから離間した位置に配置される立設部32cと、が形成されている。
腕部32bは、全体が縦断面視して略V字状に折曲されると共に、中心線上部位に上方向に向けて半円状に湾曲させて突出させた補強凸部32eが形成されている。
立設部32cは、腕部32bの先端から上方向に折曲して形成された部位であり、上端部が前記垂下部31cに溶接手段等によって接合されている。立設部32cの上側最先端部は、前側方向に向けて水平に折曲されている。
図5に示すように、第3板部材33は、第1板部材31の左側端部に溶接手段等によって一体に接合されて、平面視して略L字状の板部材である。第3板部材33には、下端部及び前側端部の縁に形成された補強用折曲部33aと、上端縁に上方向に向けて形成された突出片33bと、クラッチリザーバ22(図2参照)の当接部22dが抱持される抱持部33cと、が形成されている。
第4板部材34は、第3板部材33の左側表面に重ねるように接合された補強部材である。
上側固定部3aは、ブラケット3の上側部位を隔壁12cに当接させて、第1固定ボルト61を固定孔31dに挿入し、その第1固定ボルト61で車体11に固定される部位である。
先端部の下側固定部3bは、ブラケット3を隔壁12cに固定する部位である。下側固定部3bは、上側固定部3aから離間されて配置され、上側固定部3aよりも下側に設けられて、ブラケット3の隔壁12cへの支持スパンが大きくなっている。
図5に示すように、第1支持部3cは、ブレーキリザーバ21(図2参照)が取り付けられる補機取付用部位であり、環状部位3eにおいて、上側固定部3aと下側固定部3bとの間の上側部分に形成されている。第1支持部3cは、前述した座面31bが形成される部位であって、上側固定部3aから前方向(離間する方向)に延出して形成されている。つまり、第1支持部3cは、ブラケット3を隔壁12cに固定する上側固定部3aと下側固定部3bとの間において、上側固定部3aと水平方向に離間させて配置されている。この第1支持部3cは、隔壁12cに取り付けた際に、隔壁12cとで略環状に形成されて、環状部位3eを形成する。
図5に示すように、第2支持部3dは、ブラケット3にブレーキリザーバ21以外の補機2であるクラッチリザーバ22を取り付けるための部位である(図2参照)。第2支持部3dは、上側固定部3aから第1支持部3cと左方向(水平方向)に対向する側へ延出して形成されている。つまり、第2支持部3dは、上下方向に延出して形成されて、垂直な面でクラッチリザーバ22(図2参照)を支持する。
図2に示すように、リザーバ固定ボルト7は、ブレーキリザーバ21をブラケット3に固定するためのボルトである。
締結部材6は、ブラケット3を隔壁12c等の車体11に固定するための締結具であり、例えば、座付ボルト、汎用ボルトあるいは溶接ボルトからなる。締結部材6は、上側固定部3aを隔壁12cに固定する第1固定ボルト61と、下側固定部3bを隔壁12cに固定する第2固定ボルト62との二本からなる。
第1固定ボルト61は、隔壁12cに形成された雌ねじ部12dに螺着される。第2固定ボルト62は、隔壁12cに形成された雌ねじ部12eに螺着される。なお、雌ねじ部12d,12eは、隔壁12cの後側に固定されたナット(図示省略)でもよい。
次に、図1~図5を参照して、本発明の実施形態に係る車両用ブラケットの作用をブレーキリザーバ21を車体11に取り付けるときの取付手順と共に説明する。
この場合は、まず、ブレーキリザーバ21の取付片21fをブラケット3の第1支持部3c上に載置し、リザーバ固定ボルト7の雄ねじ部を挿通孔21j,31fに挿入して固定ナット35に螺着させることによって、ブレーキリザーバ21をブラケット3に固定させる。
注入後は、ブレーキリザーバ21からブレーキフルード真空充填治具4を取り外し、開口部21cにキャップ部21b(図1参照)を外嵌させる。
その結果、従来使用していた下支え治具500(図6参照)が不用となるため、製造ライン上での作業工数を削減することができる。
この場合、歩行者がフロントバンパによって跳ね上げられてフード13で受け止められると、フード13は、図1に二点鎖線で示すように、下側に湾曲するように変形して、衝突時の歩行者の衝撃力を十分吸収するクッション性を有している。そして、フード13が下側に大きく変形した場合には、そのフード13がエンジンルーム12内のブレーキリザーバ21のキャップ部21bを下方向に押圧することもある。
この場合は、図4に示すように、クラッチフロードを注入したクラッチリザーバ22の係合片22cを、隔壁12cに取り付けられたブラケット3の抱持部33cに挿入して、当接部22dを抱持部33cの上端に当接させることによって、クラッチリザーバ22をブラケット3に固定させることができる。
よって、ブラケット3は、クラッチリザーバ22もクッション性及び強度を兼ね備えた状態で支持することができる。
前記実施形態では、ブラケット3に取り付けられる補機2の一例として、ブレーキリザーバ21とクラッチリザーバ22を隔壁12cに取り付ける場合を例に挙げて説明したが、それ以外のタンク類や機器類や部品8であっても構わない。
このため、ブラケット3は、どのような形式の車両1であっても、部品8を取り付けるためのものとして適用することができる。
