かゝるディスクブレーキは、例えば実開平１−８０８３３号公報に開示されて いるように、既に知られている。 Such disc brakes are already known, for example, as disclosed in Japanese Utility Model Laid-Open No. 1-80833.
【０００３】[0003]
かゝるディスクブレーキでは、ブレーキキャリパの２分割により、ピストンを 装着する油圧シリンダを第１腕部に、第２腕部に何等邪魔されることなく容易に 形成し得る利点を有するが、その反面、ブレーキキャリパの剛性確保が難しく、 ブリッジ部の大きな窓孔がそれを一層困難にする。 Such a disc brake has an advantage that a hydraulic cylinder for mounting a piston can be easily formed on the first arm portion without being disturbed by the second arm portion by dividing the brake caliper into two parts. , It is difficult to secure the rigidity of the brake caliper, and the large window in the bridge makes it more difficult.
【０００４】 本考案は、かゝる事情に鑑みてなされたもので、２分割されたブレーキキャリ パの剛性を効果的に強化し得る前記ディスクブレーキ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 an object of the present invention is to provide the disc brake which can effectively enhance the rigidity of the brake caliper divided into two parts.

When the distance between the first connecting bolts is L 1 and the distance between both the second connecting bolts is L 2 , L 1 <L 2 is satisfied, and the center of the total pressing force of the piston is orthogonal to the radial line of the brake disc. When the distance from the line to the first connecting bolt is H 1 and the distance from the second connecting bolt is H 2 , set all connecting bolts on the outer peripheral surface of the brake disc so that H 1 <H 2 is satisfied. It is characterized by being arranged along.

以下、図面により、本考案を自動車用ディスクブレーキに適用した一実施例に ついて説明する。 An embodiment in which the present invention is applied to an automobile disc brake will be described below with reference to the drawings.
【０００７】 図１ないし図３において、自動車の車輪と共に回転するブレーキディスクＤの 一側にブラケットＢが隣接して配置される。このブラケットＢは自動車のナック ル（図示せず）にボルト１で固着されるもので、これにはブレーキディスクＤの 周方向に互いに離隔してブレーキディスクＤを跨ぐ一対の逆Ｕ字状部２，２（図 ６参照）が形成されている。In FIGS. 1 to 3, a bracket B is arranged adjacent to one side of a brake disc D that rotates together with a vehicle wheel. The bracket B is fixed to a knuckle (not shown) of an automobile with a bolt 1, and includes a pair of inverted U-shaped portions 2 that are spaced apart from each other in the circumferential direction of the brake disc D and straddle the brake disc D. , 2 (see FIG. 6) are formed.
【０００８】 ブラケットＢには、上記逆Ｕ字状部２，２においてブレーキキャリパＣが一対 の摺動ピン４，４を介して連結される。即ち、これら摺動ピン４，４はブレーキ キャリパＣに螺着されると共に、逆Ｕ字状部２，２の頂部に形成された袋状の支 持孔５，５に摺動自在に嵌合される。各摺動ピン４の支持孔５からの露出部は伸 縮性の防塵ブーツ６で覆われる。A brake caliper C is connected to the bracket B at the inverted U-shaped portions 2 and 2 via a pair of sliding pins 4 and 4. That is, these sliding pins 4 and 4 are screwed onto the brake caliper C and slidably fitted into bag-shaped supporting holes 5 and 5 formed on the tops of the inverted U-shaped portions 2 and 2. To be done. The exposed portion of each sliding pin 4 from the support hole 5 is covered with a stretchable dustproof boot 6.
【０００９】 ブレーキキャリパＣは、ブレーキディスクＤの両側面に摩擦パッドＰ，Ｐ′を それぞれ挟んで対向する第１及び第２腕部７1 ，７2 と、ブレーキディスクＤを 跨ぐようにこの両腕部７1 ，７2 間を一体的に連結するブリッジ部８とから構成 され、このブリッジ部８には、ブラケットＢ及び両摩擦パッドＰ，Ｐ′を臨ませ る窓孔９が設けられる。この窓孔９は、ブラケットＢのナックルへの取付時に車 両前方へ向けられる。したがって、自動車の走行中、走行風がこの窓孔９に進入 して摩擦パッドＰ，ＰやブレーキディスクＤを効果的に冷却する。The brake caliper C includes first and second arm portions 7 1 and 7 2 that are opposed to each other on both sides of the brake disc D with the friction pads P and P ′ sandwiched between the brake caliper C and the brake disc D. It is composed of a bridge portion 8 that integrally connects the arm portions 7 1 and 7 2 , and the bridge portion 8 is provided with a window hole 9 through which the bracket B and both friction pads P and P ′ are exposed. The window hole 9 is directed toward the front of the vehicle when the bracket B is attached to the knuckle. Therefore, while the automobile is traveling, the traveling wind enters the window holes 9 to effectively cool the friction pads P, P and the brake disc D.

One of the hydraulic cylinders 10 is provided with a hydraulic pressure introducing port 13 for introducing the output hydraulic pressure of a known master cylinder, and a communicating hole 14 is provided between the hydraulic cylinders 10 and 10 to connect them. Therefore, when the master cylinder is operated, the output hydraulic pressure can simultaneously pressurize both hydraulic cylinders 10, 10 to press both pistons 12, 12 against one friction pad P. The center of the total pressing force at this time is shown by O in FIG.

【００１８】 次にこの実施例の作用について説明する。 ブレーキペダルの操作により図示しないマスタシリンダを作動して、その出力 油圧を油圧導入ポート１３を通して油圧シリンダ１０，１０に供給すれば、両ピ ストン１２，１２が前進して一方の摩擦パッドＰの背面を押圧するので、該摩擦 パッドＰはハンガピン２１及びトルク受け面２２，２２上を摺動してブレーキデ ィスクＤの一側面に圧接する。すると、その反作用によりブレーキキャリパＣは 、第１及び第２摺動ピン４，４をそれぞれ支持孔５，５に摺動させながらピスト ン１２，１２の前進と反対方向に移動して、第２腕部７2 により他方の摩擦パッ ドＰ′の背面を押圧し、これをブレーキディスクＤの他側面に圧接させる。以上 により車輪と共に回転するブレーキディスクＤに制動力を加えられる。Next, the operation of this embodiment will be described. By operating a master cylinder (not shown) by operating the brake pedal and supplying the output hydraulic pressure to the hydraulic cylinders 10 and 10 through the hydraulic pressure introducing port 13, both pistons 12 and 12 move forward and the rear surface of one friction pad P is moved. Since the friction pad P is pressed, the friction pad P slides on the hanger pin 21 and the torque receiving surfaces 22 and 22 and comes into pressure contact with one side surface of the brake disk D. Then, the reaction causes the brake caliper C to move in the direction opposite to the forward movement of the pistons 12, 12 while sliding the first and second sliding pins 4, 4 in the support holes 5, 5, respectively. the arms 7 2 presses the back of the other friction pad P ', which is pressed against the other side of the brake disc D. As described above, the braking force is applied to the brake disc D that rotates with the wheels.
【００１９】 この制動中、ブレーキディスクＤから摩擦パッドＰ，Ｐ′に作用する制動トル クはブラケットＢの、ブレーキディスクＤ回転方向側のトルク受け面２２で支承 される。During this braking, the braking torque acting on the friction pads P, P ′ from the brake disc D is supported by the torque receiving surface 22 of the bracket B on the rotation direction side of the brake disc D.
【００２０】 またブレーキキャリパＣの第１及び第２腕部７1 ，７2 間には、ピストン１２ ，１２の押圧力と、それに対する反力とが拡張力として作用するが、各一対の第 １及び第２連結ボルト１６1 ，１６1 ；１６2 ，１６2 の引張り及び曲げ応力が 上記拡張力に抗してブレーキキャリパＣの第１及び第２ブロックＣ1 ，Ｃ2 の結 合状態を維持する。Further, between the first and second arm portions 7 1 and 7 2 of the brake caliper C, the pressing force of the pistons 12 1 and 12 and the reaction force against them act as an expanding force. The tensile and bending stresses of the first and second connecting bolts 16 1 , 16 1 ; 16 2 , 16 2 resist the expansion force and bring the first and second blocks C 1 , C 2 of the brake caliper C into a connected state. maintain.
【００２１】 ところで、前記（１）及び（２）式から明らかなように、第１連結ボルト１６ 1 は、ピストン１２，１２の総合押圧力中心Ｏまでの距離が第２連結ボルト１６ 2 から同押圧力中心Ｏまでの距離よりも短いので、第２連結ボルト１６2 よりも 引張応力が大きいが、曲げ応力は第１連結ボルト１６1 より第２連結ボルト１６ 2 の方が大きい。このように第１及び第２連結ボルト１６1 ，１６2 の引張応力 及び曲げ応力の分担割合を大小異らせることにより、応力の均等化が図られ、結 局第１及び第２連結ボルト１６1 ，１６2 の協働によりブレーキキャリパＣの剛 性を効果的に強化することができる。また摺動ピン４及び第１，第２連結ボルト １６1 ，１６2 は、ブレーキディスクＤとの同心円１７上に配列されるので、い ずれもブレーキディスクＤに可及的近接して配置されることになり、ブレーキキ ャリパＣのコンパクト化を図ることができる。By the way, as is apparent from the expressions (1) and (2), the first connecting bolt 16 1 Is the distance from the total pressing force center O of the pistons 12, 12 to the second connecting bolt 16 2 Is shorter than the distance from the pressing force center O to the second connecting bolt 162Although the tensile stress is larger than that of the first connecting bolt 161Second connecting bolt 16 2 Is bigger. Thus, the first and second connecting bolts 161, 162The stresses are equalized by varying the proportions of the tensile stress and the bending stress of each of the first and second connecting bolts 16.1, 162The rigidity of the brake caliper C can be effectively strengthened by the cooperation of the above. In addition, the sliding pin 4 and the first and second connecting bolts 161, 162Are arranged on the concentric circle 17 with the brake disc D, so that they are arranged as close to the brake disc D as possible, and the brake caliper C can be made compact.
【００２２】 メンテナンス時には、ハンガピン２１を外せば、直ちにブレーキキャリパＣの 窓孔９から摩擦パッドＰ，Ｐ′の抜差しができるので、摩擦パッドＰ，Ｐ′の新 規部品との交換を、ブレーキキャリパＣをブラケットＢから外すことなく容易に 行うことができる。At the time of maintenance, if the hanger pin 21 is removed, the friction pads P and P'can be immediately inserted and removed from the window hole 9 of the brake caliper C. Therefore, the friction pads P and P'can be replaced with new parts. It can be easily performed without removing C from the bracket B.
【００２３】 尚、上記実施例では、第１腕部７1 に一対のピストン１２，１２を設けたが、 本考案はピストン１２を１個または３個以上とすることもできる。Although the pair of pistons 12, 12 are provided in the first arm portion 7 1 in the above embodiment, the present invention may have one piston 3 or three or more.

以上のように本考案によれば、ブレーキキャリパの第１及び第２ブロックを、 それぞれ窓孔を挟んで並列する各一対の第１及び第２連結ボルトにより一体に連 結し、両第１連結ボルト間の距離をＬ1 、両第２連結ボルト間の距離をＬ2 とし たとき、Ｌ1 ＞Ｌ2 を満足させ、またピストンの総合押圧力中心でブレーキディ スクの半径線と直交する線から第１連結ボルトまでの距離をＨ1 、第２連結ボル トまでの距離をＨ2 としたとき、Ｈ1 ＜Ｈ2 を満足させるように、全連結ボルト をブレーキディスクの外周面に沿って配列したので、第１及び第２連結ボルトの 引張及び曲げ応力の分担割合を大小異らせて、応力の均等化を図ることができ、 したがって第１及び第２連結ボルトの協働によりブレーキキャリパの剛性を効果 的に強化することができる。しかもいずれの連結ボルトもブレーキディスクに可 及的近接して配置されるので、ブレーキキャリパのコンパクト化にも寄与し得る 。As described above, according to the present invention, the first and second blocks of the brake caliper are integrally connected to each other by the pair of first and second connecting bolts which are arranged in parallel with each other with the window hole interposed therebetween. When the distance between bolts is L 1 and the distance between both second connecting bolts is L 2 , L 1 > L 2 is satisfied, and a line orthogonal to the radius line of the brake disc at the center of the total pressing force of the piston. From the first connecting bolt to H 1 and the second connecting bolt to H 2 , set all connecting bolts along the outer peripheral surface of the brake disc so that H 1 <H 2 is satisfied. Since they are arranged, the proportions of the tensile and bending stresses of the first and second connecting bolts can be made different to make the stress equalization. Therefore, the cooperation of the first and second connecting bolts allows the brake caliper to cooperate. Effectively strengthening the rigidity of It can be. Moreover, both connecting bolts are arranged as close to the brake disc as possible, which can contribute to the compactness of the brake caliper.
