Description
【０００１】[0001]
本考案は、主として自動車の２系統式ブレーキ装置に用いられるマスタシリン ダ及びリザーバの組立体に関し、特に、タンデム型マスタシリンダの第１及び第 ２作動油導入筒に、単一のリザーバ下面に突設された第１及び第２送油管をシー ル部材を介してそれぞれ嵌入し、両作動油導入筒の間を横切るように配置される 連結ボルトによりマスタシリンダ及びリザーバを相互に連結したものゝ改良に関 する。 The present invention relates to an assembly of a master cylinder and a reservoir mainly used in a two-system brake device of an automobile, and more particularly, to a first reservoir and a second hydraulic fluid introducing cylinder of a tandem master cylinder, which are provided on a lower surface of a single reservoir. The first and second oil supply pipes are inserted through the seal members, respectively, and the master cylinder and the reservoir are connected to each other by connecting bolts that are arranged so as to cross between the hydraulic oil introducing cylinders. To be involved.

かゝる組立体は、例えば実開昭５６−１７００５９号公報に開示されているよ うに、既に知られている。 Such an assembly is already known, for example, as disclosed in Japanese Utility Model Publication No. 56-170059.
【０００３】[0003]
一般にかゝる組立体における連結ボルトは、他物との干渉を避けて両作動油導 入筒の中央から一方へ偏らせて配置されている。それにも拘わらずマスタシリン ダの第１、第２作動油導入筒、並びにリザーバの第１、第２出口管はそれぞれ互 いに同寸法に形成されている。したがって、かゝる組立体及びそれに連なる油圧 回路に作動油を充填する際、作動油ガンを使用してリザーバの給油口筒から作動 油を高圧で供給する圧送方式を採用すると、作動油の充填圧力が各作動油導入筒 内でリザーバを押上げる力を発生し、これらによってリザーバには方向が反対の ２つのモーメントが作用するが、前述の寸法設定により両モーメントの大きさが 相違するため、傾動モーメントが発生し、これによりリザーバが傾動して、各作 動油導入筒及び送油管の間のシール部材を変形させ、そのシール機能を損じる虞 れがある。 In general, the connecting bolts in such an assembly are arranged so as to be offset from the center of both hydraulic oil introducing cylinders to one side while avoiding interference with other objects. Nevertheless, the first and second hydraulic oil introducing cylinders of the master cylinder and the first and second outlet pipes of the reservoir are formed to have the same size. Therefore, when filling such an assembly and the hydraulic circuit connected to it with hydraulic oil, if a pressure feed system is used in which the hydraulic oil gun is used to supply the hydraulic oil at a high pressure from the oil supply port cylinder of the reservoir, The pressure generates a force that pushes up the reservoir in each hydraulic oil introducing cylinder, and these exert two moments in opposite directions on the reservoir. However, the magnitudes of both moments differ due to the above-mentioned dimension setting. A tilting moment is generated, which tilts the reservoir, which may deform the seal member between each working oil introducing cylinder and the oil feed pipe, and impair the sealing function.
【０００４】 本考案は、かゝる事情に鑑みてなされたもので、圧送方式によりリザーバから 作動油を充填するとき、リザーバに傾動モーメントが発生しないようにした、前 記マスタシリンダ及びリザーバの組立体を提供することを目的とする。The present invention has been made in view of such circumstances, and when the hydraulic oil is filled from the reservoir by the pressure feeding method, the tilting moment is prevented from being generated in the reservoir. The purpose is to provide a solid.
【０００５】[0005]
上記目的を達成するために、本考案は、リザーバに、その給油口筒の開放端に 押し当てられる作動油ガンを係止させる係止部を設け、第１作動油導入筒でのリ ザーバの軸方向受圧面積をＡ1 、第２作動油導入管でのリザーバの軸方向受圧面 積をＡ2 、第１作動油導入筒及び連結ボルト間の距離をＬ1 、第２作動油導入筒 及び連結ボルト間の距離をＬ2 としたとき、これらの寸法を次式、 Ａ1 ・Ｌ1 ＝Ａ2 ・Ｌ2 が成立するように設定したことを特徴とする。In order to achieve the above object, the present invention provides a reservoir with a locking portion that locks a hydraulic oil gun that is pressed against the open end of the oil supply cylinder, and the reservoir of the first hydraulic oil introducing cylinder is provided. The axial pressure receiving area is A 1 , the axial pressure receiving area of the reservoir in the second hydraulic oil introducing pipe is A 2 , the distance between the first hydraulic oil introducing pipe and the connecting bolt is L 1 , the second hydraulic oil introducing pipe and When the distance between the connecting bolts is L 2 , these dimensions are set so that the following equation, A 1 · L 1 = A 2 · L 2 is established.
【０００６】[0006]
以下、図面により本考案の一実施例について説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【０００７】 先ず図１において、自動車のブレーキ用マスタシリンダＭは、シリンダ本体１ のシリンダ孔１ａに前後一対のピストン２ｆ，２ｒを摺動自在に嵌装してタンデ ム型に構成される。シリンダ孔１ａの内部は両ピストン２ｆ，２ｒにより前、後 部油圧室３ｆ，３ｒに区画され、これら油圧室３ｆ，３ｒの出力ポート４ｆ，４ ｒは、シリンダ本体１の外側面に突設された出力ボス５ｆ，５ｒに穿設される。 出力ボス５ｆ，５ｒには、前、後輪ブレーキＢｆ，Ｂｒにそれぞれ連なる油圧導 管６ｆ，６ｒがそれぞれ接続される。而して、図示しないブレーキペダルにより プッシュロッド７を介して後部ピストン２ｒを前方へ押動すれば、油圧室３ｆ， ３ｒに発生した油圧を出力ポート４ｆ，４ｒから出力させて前、後輪ブレーキペ ダルＢｆ，Ｂｒへそれぞれ供給し、それらを作動させることができる。First, in FIG. 1, a master cylinder M for a brake of an automobile is constructed in a tandem type in which a pair of front and rear pistons 2f and 2r are slidably fitted in a cylinder hole 1a of a cylinder body 1. The inside of the cylinder hole 1a is divided into front and rear hydraulic chambers 3f and 3r by both pistons 2f and 2r, and the output ports 4f and 4r of these hydraulic chambers 3f and 3r are provided on the outer surface of the cylinder body 1 so as to project therefrom. The output bosses 5f and 5r are provided. The output bosses 5f and 5r are respectively connected to hydraulic guide pipes 6f and 6r connected to the front and rear wheel brakes Bf and Br, respectively. When the rear piston 2r is pushed forward via the push rod 7 by a brake pedal (not shown), the hydraulic pressure generated in the hydraulic chambers 3f, 3r is output from the output ports 4f, 4r, and the front and rear wheel brake pedals are output. It can be supplied to the dulls Bf and Br, respectively, to activate them.
【０００８】 シリンダ本体１の上面には、前、後部油圧室３ｆ，３ｒにそれぞれ作動油を補 給し得る前後一対の第１及び第２作動油導入筒８ｆ，８ｒが一体に突設されてお り、作動油を貯留する合成樹脂製のリザーバＲの下面に一体に突設された前後一 対の第１及び第２送油管９ｆ，９ｒが上記第１及び第２作動油導入筒８ｆ，８ｒ にグロメット型のシール部材１０ｆ，１０ｒをそれぞれ介して嵌入される。On the upper surface of the cylinder body 1, a pair of front and rear first and second hydraulic oil introducing cylinders 8f and 8r capable of supplying hydraulic oil to the front and rear hydraulic chambers 3f and 3r, respectively, are integrally projected. The pair of front and rear first and second oil feed pipes 9f and 9r integrally provided on the lower surface of the reservoir R made of synthetic resin for storing the hydraulic oil are the first and second hydraulic oil introduction cylinders 8f, The grommet type sealing members 10f and 10r are fitted into the 8r.
【０００９】 両作動油導入筒８ｆ，８ｒ間において、シリンダ本体１及びリザーバＲの相対 向面には、図３に示すように互いに重なる連結腕１１，１２が一体に突設される 。リザーバＲの連結腕１１には金属製のカラー１３が埋設され、またシリンダ本 体１の連結腕１２にはねじ孔１４が穿設され、カラー１３に挿通された連結ポー ト１５をねじ孔１４に螺合、緊締することにより、両連結腕１１，１２は結合さ れる。その場合、連結ボルト１５は、その着脱を容易にするために、両作動油導 入筒８ｆ，８ｒ間を横切るように配置される。As shown in FIG. 3, connecting arms 11 and 12 that overlap with each other are integrally provided on the relative surfaces of the cylinder body 1 and the reservoir R between the two hydraulic oil introducing cylinders 8 f and 8 r. A metal collar 13 is embedded in the connecting arm 11 of the reservoir R, and a screw hole 14 is formed in the connecting arm 12 of the cylinder body 1, and the connecting port 15 inserted into the collar 13 is screwed into the screw hole 14. The connecting arms 11 and 12 are joined by screwing and tightening. In this case, the connecting bolt 15 is arranged so as to cross between the hydraulic oil introducing cylinders 8f and 8r in order to facilitate its attachment and detachment.
【００１０】 図２に示すように、第１作動油導入管８ｆ及び連結ボルト１５間の距離をＬ1 、第２作動油導入筒８ｒ及び連結ボルト１５間の距離をＬ2 、第１作動油導入筒 ８ｆにおけるリザーバＲの軸方向受圧面積をＡ1 、第２作動油導入筒８ｒにおけ るリザーバＲの軸方向受圧面積をＡ2 としたとき、これらの寸法は下記（１）式 が成立するように設定される。As shown in FIG. 2, the distance between the first hydraulic oil introducing pipe 8f and the connecting bolt 15 is L 1 , the distance between the second hydraulic oil introducing cylinder 8r and the connecting bolt 15 is L 2 , the first hydraulic oil. When the axial pressure receiving area of the reservoir R in the introduction cylinder 8f is A 1 and the axial pressure receiving area of the reservoir R in the second hydraulic oil introduction cylinder 8r is A 2 , these dimensions satisfy the following formula (1). Is set to do.
【００１１】 Ａ1 ・Ｌ1 ＝Ａ2 ・Ｌ2 ………（１） 図示例の場合、シール部材１０ｆ，１０ｒは、各下端に形成されたシールリッ プ１０ａを対応する作動油導入筒８ｆ，８ｒの内周面に密接させている。したが って、各作動油導入筒８ｆ，８ｒにおけるリザーバＲの軸方向受圧面積Ａ1 ，Ａ 2 は、シールリップ１０ａの外径Ｄ1 ，Ｄ2 と送油管９ｆ，９ｒの内径ｄ1 ，ｄ 2 との間の面積、即ち Ａ1 ＝π（Ｄ1 −ｄ1 ）2 ／４ ……（２） Ａ2 ＝π（Ｄ2 −ｄ2 ）2 ／４ ……（３） となる。A1・ L1= A2・ L2 (1) In the illustrated example, the seal members 10f and 10r have the seal lip 10a formed at the lower end thereof in close contact with the inner peripheral surfaces of the corresponding hydraulic oil introducing cylinders 8f and 8r. Accordingly, the axial pressure receiving area A of the reservoir R in each hydraulic oil introducing cylinder 8f, 8r1, A 2 Is the outer diameter D of the seal lip 10a1, D2And the inner diameter d of the oil transfer pipes 9f and 9r1, D 2 Area between and1= Π (D1-D1)2/ 4 (2) A2= Π (D2-D2)2/ 4 (3)
【００１２】 また図示例の場合、後部出力ボス４ｒは、両作動油導入筒８ｆ，８ｒの中央部 のシリンダ本体１上面に僅かに***するように配置されており、これと干渉しな いように連結腕１１，１２は後部出力ボス４ｒより僅か後方に配置される。その 結果、第１作動油導入筒８ｆ及び連結ボルト１５間の距離Ｌ1 は、第２作動油導 入筒８ｒ及び連結ボルト１５間の距離Ｌ2 より大きくなっている。したがって、 前記（１）式を満足させるために、前記Ａ2 はＡ1 より大きく設定される。Further, in the case of the illustrated example, the rear output boss 4r is arranged so as to slightly bulge on the upper surface of the cylinder body 1 in the central portion of both the hydraulic oil introducing cylinders 8f and 8r, so that it does not interfere with this. The connecting arms 11 and 12 are arranged slightly rearward of the rear output boss 4r. As a result, the distance L 1 between the first hydraulic oil introducing cylinder 8f and the connecting bolt 15 is larger than the distance L 2 between the second hydraulic oil introducing cylinder 8r and the connecting bolt 15. Therefore, in order to satisfy the expression (1), A 2 is set to be larger than A 1 .
【００１３】 再び図１において、リザーバＲの上面には、開放端外周にフランジ１６ａ（係 止部）を有する給油口筒１６が一体に突設されており、その開放端には、通常、 キャップ１７が嵌められる。またリザーバＲの底壁には、その内部で両送油管９ ｆ，９ｒの間を仕切る隔壁が一体に形成される。Referring again to FIG. 1, on the upper surface of the reservoir R, an oil supply port cylinder 16 having a flange 16a (locking portion) on the outer periphery of the open end is integrally projected, and the open end thereof is usually a cap. 17 is fitted. Further, a partition wall is formed integrally with the bottom wall of the reservoir R so as to partition the two oil feed pipes 9f and 9r therein.
【００１４】 図４により、マスタシリンダＭから前、後輪ブレーキＢｆ，Ｂｒに至る油圧系 に作動油を充填するための作動油ガンＧについて説明する。作動油ガンＧは、中 心部に噴油孔１８を有するガン本体１９と、このガン本体１９の両側部に開閉可 能に軸支される一対のロック爪２０とからなっており、ガン本体１９の下端部に は、リザーバＲの給油口筒１６上面に密着させるパッキング２１が付設される。 各ロック爪２０は、図示しないアクチュエータにより開閉作動されるもので、そ の開き状態で前記給油口筒１６のフランジ１６ａから離脱し、閉じ状態で該フラ ンジ１６ａの下面に係合するようになっている。A hydraulic oil gun G for filling the hydraulic system from the master cylinder M to the front and rear wheel brakes Bf and Br with hydraulic oil will be described with reference to FIG. The hydraulic oil gun G is composed of a gun body 19 having a spray oil hole 18 in the center thereof, and a pair of lock claws 20 rotatably supported on both sides of the gun body 19, and the gun body At the lower end of 19, a packing 21 is attached to be brought into close contact with the upper surface of the fuel filler tube 16 of the reservoir R. Each of the lock claws 20 is opened and closed by an actuator (not shown). When the lock claws 20 are opened, the lock claws 20 are disengaged from the flange 16a of the fuel filler cylinder 16, and are engaged with the lower surface of the flange 16a in the closed state. ing.
【００１５】 次にこの実施例の作用について説明する。Next, the operation of this embodiment will be described.
【００１６】 マスタシリンダＭから前、後輪ブレーキＢｆ，Ｂｒに至る油圧系に作動油を充 填する際には、図４に示すように、キャップ１７を外した状態でリザーバＲの給 油口筒１６上端面にパッキング２１を介してガン本体１９を押し当て、ロック爪 ２０を閉じてフランジ１６ａの下面に係合させる。こうして作動油ガンＧをリザ ーバＲに係止してからガン本体１９の噴油孔１８から高圧をもって作動油をリザ ーバＲ内に供給すると、その作動油は第１，第２送油管９ｆ，９ｒからマスタシ リンダＭの前、後部油圧室３ｆ，３ｒへ、更に油圧導管６ｆ，６ｒを経て前、後 輪ブレーキＢｆ，Ｂｒへと充填される。その際、前、後輪ブレーキＢｆ，Ｂｒの ブリード栓は開けて、油圧系の空気の排出を同時に行うものである。When filling the hydraulic system from the master cylinder M to the front and rear wheel brakes Bf and Br with hydraulic oil, as shown in FIG. 4, the oil supply port of the reservoir R is removed with the cap 17 removed. The gun body 19 is pressed against the upper end surface of the cylinder 16 via the packing 21, and the lock claw 20 is closed to engage with the lower surface of the flange 16a. In this way, when the hydraulic oil gun G is locked to the reservoir R and then the hydraulic oil is supplied into the reservoir R with a high pressure from the injection oil hole 18 of the gun body 19, the hydraulic oil is supplied to the first and second oil pipes. The front and rear hydraulic chambers 3f and 3r are filled from 9f and 9r to the front and rear hydraulic chambers 3f and 3r, and the front and rear wheel brakes Bf and Br are further filled via hydraulic conduits 6f and 6r. At that time, the bleed plugs of the front and rear wheel brakes Bf and Br are opened to discharge the hydraulic system air at the same time.
【００１７】 ところで、作動油の充填時、その充填圧力ｐが各作動油導入筒８ｆ，８ｒにそ れぞれ作用すると、リザーバＲには、図２に示すように、互いに方向が反対の下 記２つのモーメントｍ1 ，ｍ2 が加わる。By the way, when the filling pressure p of the hydraulic oil acts on each of the hydraulic oil introducing cylinders 8f and 8r at the time of filling the hydraulic oil, as shown in FIG. Note Two moments m 1 and m 2 are added.
【００１８】 ｍ1 ＝ｐ・Ａ1 ・Ｌ1 ……（４） ｍ2 ＝ｐ・Ａ2 ・Ｌ2 ……（５） しかしながら、前記（１）式で示したように、Ａ1 ・Ｌ1 ＝Ａ2 ・Ｌ2 である から、ｍ1 ＝ｍ2 となる。結局、リザーバＲに傾動モーメントは発生せず、連結 ボルト１５周りに傾くことがない。したがってシール部材１０ｆ，１０ｒの無用 な変形を未然に防止し得る。M 1 = p · A 1 · L 1 (4) m 2 = p · A 2 · L 2 (5) However, as shown in the equation (1), A 1 · L Since 1 = A 2 · L 2 , m 1 = m 2 . After all, no tilting moment is generated in the reservoir R, and the reservoir R does not tilt around the connecting bolt 15. Therefore, unnecessary deformation of the seal members 10f and 10r can be prevented.
【００１９】 尚、上記実施例においては、本考案の要旨を逸脱することなく、種々の設計変 更が可能である。例えば、Ｌ1 ＝Ｌ2 となるように連結ボルト１５を配置した場 合には、前記（１）式に従いＡ1 ＝Ａ2 に設定すればよい。In the above embodiment, various design changes can be made without departing from the gist of the present invention. For example, when the connecting bolts 15 are arranged so that L 1 = L 2 , it may be set to A 1 = A 2 according to the equation (1).
【００２０】[0020]
以上のように本考案によれば、リザーバに、その給油口筒の開放端に押し当て られる作動油ガンを係止させる係止部を設け、第１作動油導入筒でのリザーバの 軸方向受圧面積をＡ1 、第２作動油導入管でのリザーバの軸方向受圧面積をＡ2 、第１作動油導入筒及び連結ボルト間の距離をＬ1 、第２作動油導入筒及び連結 ボルト間の距離をＬ2 としたとき、これらの寸法を次式、 Ａ1 ・Ｌ1 ＝Ａ2 ・Ｌ2 が成立するように設定したので、作動油ガンによる作動油のリザーバからの充填 時、その充填圧力による傾動モーメントの発生を防止して、リザーバの連結ボル ト周りの傾動を抑えることができ、したがって各作動油導入筒及び送油管の間の シール部材の無用な変形を防止してそのシール機能を確保することができる。As described above, according to the present invention, the reservoir is provided with the locking portion for locking the hydraulic oil gun that is pressed against the open end of the oil supply port cylinder, and the axial pressure receiving of the reservoir in the first hydraulic oil introducing cylinder is performed. The area is A 1 , the axial pressure receiving area of the reservoir in the second hydraulic oil introducing pipe is A 2 , the distance between the first hydraulic oil introducing cylinder and the connecting bolt is L 1 , the second hydraulic oil introducing cylinder and the connecting bolt are between When the distance is L 2 , these dimensions are set so that the following equation, A 1 · L 1 = A 2 · L 2, is established. Therefore, when filling the hydraulic oil from the reservoir with the hydraulic oil gun, The tilting moment due to pressure can be prevented and tilting around the connecting bolt of the reservoir can be suppressed. Therefore, unnecessary deformation of the seal member between each hydraulic oil introducing cylinder and the oil feed pipe can be prevented, and its sealing function can be prevented. Can be secured.
