Description

本発明は、ブレーキペダルと、ピン部材を介してブレーキペダルが揺動可能に接続された連係部材と、当該連係部材を介して前記ブレーキペダルに加えられる操作力が伝達され、当該操作力に基づいてブレーキ液圧回路にブレーキ液圧を付与するマスタシリンダとを備えたブレーキ装置に関する。   The present invention relates to a brake pedal, a linkage member that is swingably connected via a pin member, and an operating force applied to the brake pedal via the linkage member, and is based on the operating force. The present invention relates to a brake device including a master cylinder that applies brake fluid pressure to a brake fluid pressure circuit.

この種のブレーキ装置においては、ブレーキペダルに対する操作量が少ないブレーキ操作初期にマスタシリンダ側で発生した振動がブレーキペダルに伝達されやすい。そこで、この種のブレーキ装置では、ブレーキペダルに振動が伝わるのを防止するために、ブレーキペダルとマスタシリンダとの間に振動防止装置を設ける場合がある。従来、このような振動防止装置として、例えば特許文献１及び特許文献２に記載されたものが公知である。この振動防止装置は、連係部材として、マスタシリンダに連結されるロッドと、ロッドに対してブレーキペダルを揺動可能に連結するクレビスとを備えている。このロッドの端部とクレビスの端部とは、装置を構成するリテイナーの内部で対向している。当該ロッドの端部及びクレビスの端部には夫々フランジが設けてあり、このフランジの間に弾性を有するクッション部材を配置してある。このように、ロッドとクレビスとの間にクッション部材を介装することにより、マスタシリンダ側からの振動がブレーキペダルに伝達されるのを防止している。   In this type of brake device, vibration generated on the master cylinder side at the initial stage of brake operation with a small amount of operation with respect to the brake pedal is easily transmitted to the brake pedal. Therefore, in this type of brake device, there is a case where a vibration preventing device is provided between the brake pedal and the master cylinder in order to prevent vibration from being transmitted to the brake pedal. Conventionally, as such a vibration preventing device, for example, those described in Patent Document 1 and Patent Document 2 are known. This vibration preventing device includes a rod connected to a master cylinder and a clevis for connecting a brake pedal so as to be able to swing with respect to the rod. The end of this rod and the end of the clevis are opposed to each other inside the retainer constituting the device. A flange is provided at each of the end of the rod and the end of the clevis, and an elastic cushion member is disposed between the flanges. In this way, by interposing the cushion member between the rod and the clevis, vibration from the master cylinder side is prevented from being transmitted to the brake pedal.

しかし、上述の装置では、クッション部材の他に、当該クッション部材を介装するための部材として、フランジやリテイナーが必要となり部品点数が増加して、製造工程が煩雑になる。   However, in the above-described apparatus, in addition to the cushion member, a flange or a retainer is required as a member for interposing the cushion member, so that the number of parts increases and the manufacturing process becomes complicated.

本発明は、上述の問題点に鑑みてなされたものであり、より簡素な構造を有すると共に、ブレーキペダルの振動を有効に防止するブレーキ装置を提供することにある。   The present invention has been made in view of the above-described problems, and has an object to provide a brake device that has a simpler structure and effectively prevents vibration of a brake pedal.

本発明の第１特徴構成は、ブレーキペダルと、ピン部材を介して前記ブレーキペダルが揺動可能に接続された連係部材と、当該連係部材を介して前記ブレーキペダルに接続し、当該ブレーキペダルに対するブレーキ操作に従って、接続するブレーキ液圧回路にブレーキ液圧を付与するマスタシリンダとを備え、前記ブレーキ操作が所定の操作量を超える前には、前記ブレーキペダルと前記ピン部材、及び、前記ピン部材と前記連係部材、とが直接に当接することがなく、所定の操作量を超えた後に、前記ブレーキペダルと前記ピン部材、及び、前記ピン部材と前記連係部材、とが直接に当接するよう、前記ブレーキペダルと前記ピン部材との間、或いは、前記ピン部材と前記連係部材との間に弾性部材を設けた点にある。 A first characteristic configuration of the present invention includes a brake pedal, a linkage member to which the brake pedal is swingably connected via a pin member, and the brake pedal connected to the brake pedal via the linkage member. A master cylinder that applies brake fluid pressure to a brake fluid pressure circuit to be connected in accordance with a brake operation, and before the brake operation exceeds a predetermined operation amount, the brake pedal, the pin member, and the pin member So that the brake pedal and the pin member, and the pin member and the linkage member directly abut after exceeding a predetermined operation amount without directly contacting the linkage member. An elastic member is provided between the brake pedal and the pin member or between the pin member and the linkage member.

上述の構成により、ブレーキ操作が所定の操作量を超えるまでのブレーキ操作の初期は、ブレーキペダル・ピン部材・前記連係部材が直接当接するのではなく、弾性部材を介してブレーキペダルへの操作力が連係部材に伝達されることになる。このため、マスタシリンダ側で振動が発生した場合であっても、弾性部材で振動を減衰することにより、振動がブレーキペダルまで伝達されることを防止することができる。また、ブレーキペダルとピン部材との間、或いは、ピン部材と連係部材との間に弾性部材を設けるだけでよいので、ブレーキ装置の構造を簡素化できると共に、部品点数を削減でき、製造工程を簡略化することができる。   With the above-described configuration, in the initial stage of the brake operation until the brake operation exceeds the predetermined operation amount, the brake pedal, the pin member, and the linkage member do not directly contact each other, but the operation force applied to the brake pedal via the elastic member Is transmitted to the linkage member. For this reason, even when vibration occurs on the master cylinder side, the vibration can be prevented from being transmitted to the brake pedal by attenuating the vibration with the elastic member. Moreover, since it is only necessary to provide an elastic member between the brake pedal and the pin member, or between the pin member and the linking member, the structure of the brake device can be simplified, the number of parts can be reduced, and the manufacturing process can be reduced. It can be simplified.

本発明の第２特徴構成は、前記弾性部材は、前記ピン部材の外周に巻き回したゴム部材であり、前記ブレーキペダル或いは前記連係部材は、ブレーキ操作の当初に前記ゴム部材に当接する第１当接部と、その後のブレーキ操作に際して前記ピン部材に当接する第２当接部とを備えた点にある。   According to a second characteristic configuration of the present invention, the elastic member is a rubber member wound around the outer periphery of the pin member, and the brake pedal or the linking member contacts the rubber member at the beginning of a brake operation. The contact portion includes a contact portion and a second contact portion that contacts the pin member during a subsequent brake operation.

本構成のごとく、ピン部材の外周にゴム部材を巻き回すものであれば、構成が非常に簡単であるうえに、組立て時および使用時においてピン部材が回転した場合でも方向性が問題となることはない。よって、構造および組立性等において合理的なブレーキ装置を得ることができる。   If the rubber member is wound around the outer periphery of the pin member as in this configuration, the configuration is very simple, and directionality becomes a problem even when the pin member rotates during assembly and use. There is no. Therefore, it is possible to obtain a brake device that is rational in terms of structure and assemblability.

本発明の第３特徴構成は、前記ピン部材の外周に前記ゴム部材が嵌り込む小径部を備えた点にある。   The third characteristic configuration of the present invention is that a small-diameter portion into which the rubber member is fitted on the outer periphery of the pin member is provided.

ピン部材の周囲に巻き回したゴム部材をブレーキペダル等で圧縮する場合、ゴム部材の機能を繰り返し利用するためには、ゴム部材を完全に圧縮するのは得策ではない。この点、本構成では、ゴム部材がピン部材の外周に設けた小径部に嵌り込んだ状態で固定されているから、ゴム部材の圧縮程度を、ある程度の弾性が発揮される状態に留めておくことができる。
また、例えば、小径部の深さとゴム部材の厚みとを適宜設定することで、発揮される弾性力を容易に調節することができ、設計の自由度に富んだブレーキ装置を得ることができる。 When the rubber member wound around the pin member is compressed with a brake pedal or the like, it is not a good idea to completely compress the rubber member in order to repeatedly use the function of the rubber member. In this respect, in this configuration, since the rubber member is fixed in a state of being fitted into a small diameter portion provided on the outer periphery of the pin member, the degree of compression of the rubber member is kept in a state where a certain degree of elasticity is exhibited. be able to.
In addition, for example, by appropriately setting the depth of the small diameter portion and the thickness of the rubber member, the elastic force exerted can be easily adjusted, and a brake device with a high degree of design freedom can be obtained.

本発明の第４特徴構成は、前記弾性部材が、前記ピン部材と前記ブレーキペダルとの間に介装したばね部材であり、前記ブレーキペダル或いは前記連係部材は、ブレーキ操作の当初に前記ばね部材に当接する第１当接部と、その後のブレーキ操作に際して前記ピン部材に当接する第２当接部とを備えた点にある。   According to a fourth aspect of the present invention, the elastic member is a spring member interposed between the pin member and the brake pedal, and the brake pedal or the linking member is the spring member at the beginning of a brake operation. And a second abutting portion that abuts against the pin member during a subsequent brake operation.

上述の構成のごとく、ゴム以外の弾性部材としてばね部材をピン部材とブレーキペダルとの間に介装することもできる。本構成によっても比較的簡単な構造で振動を防止することができる。   As described above, a spring member can be interposed between the pin member and the brake pedal as an elastic member other than rubber. Also with this configuration, vibration can be prevented with a relatively simple structure.

以下、本発明の実施形態を図面に基づいて説明する。図１は、本発明のブレーキ装置の構成を模式的に示す概略図である。図１に示すように、ブレーキ装置は、ブレーキペダル１に対する操作に基づいて作動し、ブレーキ液圧回路６にブレーキ液圧を付与するマスタシリンダ５を備えている。ブレーキ液圧回路６は、車両の各車輪に対応して設けられたホイールシリンダ７にブレーキ液圧を付与し、各車輪を制動する。ブレーキペダル１に与えられた操作力は、ピン部材３によりブレーキペダル１が揺動可能に支持された連係部材２を介してブースタ４に伝達され、該ブースタ４によって増幅されてマスタシリンダ５に伝えられる。
このブレーキ装置においては、ブレーキペダル１とピン部材３との間に弾性部材８（図２参照）が設けられている。ブレーキ操作が所定の操作量を超える前のブレーキペダル１の踏み操作の初期においては、ブレーキペダル１・ピン部材３・連係部材２の全てが直接に当接せず、ブレーキ操作が所定の操作量を超えるその後のブレーキ操作に際しては、これらの部材が全て直に当接してブレーキ操作力をマスターシリンダに伝えるように構成してある。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view schematically showing the configuration of the brake device of the present invention. As shown in FIG. 1, the brake device includes a master cylinder 5 that operates based on an operation on the brake pedal 1 and applies brake fluid pressure to the brake fluid pressure circuit 6. The brake fluid pressure circuit 6 applies brake fluid pressure to a wheel cylinder 7 provided corresponding to each wheel of the vehicle to brake each wheel. The operating force applied to the brake pedal 1 is transmitted to the booster 4 via the linkage member 2 in which the brake pedal 1 is swingably supported by the pin member 3, amplified by the booster 4, and transmitted to the master cylinder 5. It is done.
In this brake device, an elastic member 8 (see FIG. 2) is provided between the brake pedal 1 and the pin member 3. In the initial stage of the stepping operation of the brake pedal 1 before the brake operation exceeds a predetermined operation amount, the brake pedal 1, the pin member 3, and the linkage member 2 are not in direct contact with each other, and the brake operation has a predetermined operation amount. When the brake operation is subsequently exceeded, all of these members are in direct contact with each other and transmit the brake operation force to the master cylinder.

図２は、図１のＩＩ−ＩＩ断面図である。図２に示すように連係部材２は、ブレーキペダル１に与えられるブレーキ操作力をブースタ４に伝達するロッド２３と、ロッド２３の端部に設けられたクレビス２１とを備える。ピン部材３は、クレビス２１に形成された穴部２２とブレーキペダル１に形成された穴部１１とに亘って挿通される。これにより、ブレーキペダル１は連係部材２に対して揺動可能になっている。   2 is a cross-sectional view taken along the line II-II in FIG. As shown in FIG. 2, the linkage member 2 includes a rod 23 that transmits a brake operation force applied to the brake pedal 1 to the booster 4, and a clevis 21 provided at an end of the rod 23. The pin member 3 is inserted through the hole 22 formed in the clevis 21 and the hole 11 formed in the brake pedal 1. Thereby, the brake pedal 1 can swing with respect to the linkage member 2.

ピン部材３は、断面円形状を有する。円形状であれば、ピン部材３の方向性がないため、製造時および組み付け時において取り扱いが容易となる。また、ピン部材３は、長手方向中央部に小径部３１が形成され、当該小径部３１を挟んで両側に小径部３１よりも径の大きい大径部３２が形成されている。小径部３１には、ゴム部材８１が巻き回され、ゴム部材８１の外周面は、大径部３２の外周面より径方向外側に突出している。ピン部材３のうちこのゴム部材８１を巻き回した領域は、ブレーキペダル１の穴部１１の幅方向中央部に位置させる。
なお、小径部３１をピン部材３自体の径とし、大径部３２はピン部材３の両端部に別部材のカラー等を取り付けても良い。また、同径のピン部材３にゴム部材８１を巻き回しても良い。ピン部材３の断面形状は、円形状に限られるものではなく、例えば六角形状など、何れの形状であっても良い。 The pin member 3 has a circular cross section. If it is circular, since the direction of the pin member 3 is not present, handling becomes easy during manufacturing and assembly. The pin member 3 has a small-diameter portion 31 formed at the center in the longitudinal direction, and large-diameter portions 32 having a diameter larger than that of the small-diameter portion 31 on both sides of the small-diameter portion 31. A rubber member 81 is wound around the small diameter portion 31, and the outer peripheral surface of the rubber member 81 protrudes radially outward from the outer peripheral surface of the large diameter portion 32. The region of the pin member 3 around which the rubber member 81 is wound is positioned at the center in the width direction of the hole 11 of the brake pedal 1.
The small-diameter portion 31 may be the diameter of the pin member 3 itself, and the large-diameter portion 32 may be provided with a collar or the like of another member at both ends of the pin member 3. Further, the rubber member 81 may be wound around the pin member 3 having the same diameter. The cross-sectional shape of the pin member 3 is not limited to a circular shape, and may be any shape such as a hexagonal shape.

図２に示すように、乗員がブレーキペダル１を操作すると、操作量が所定の値を超える前のブレーキ操作の初期においては、ゴム部材８１とブレーキペダル１とが当接して、ブレーキペダル１に対する操作力がゴム部材８１を介して連係部材２に伝達される（図２（ａ））。さらに操作を続けると、ゴム部材８１が弾性変形して押しつぶされ、ピン部材３の大径部３２とブレーキペダル１の穴部１１の内周面とが直接当接して、ブレーキペダル１に対する操作力がクレビス２１（連係部材２）に伝達される（図２（ｂ））。このように、ブレーキ操作の初期であってブレーキ操作量が所定の値を超えるまでの間は、ブレーキペダル１・ピン部材３・連係部材２の全てが直に当接する状態となることが阻止される。その後のブレーキ操作に際して、ブレーキ操作量が所定の値を超えると、これらの部材のうちゴム部材８１を挟む二つの部材同士が当接するようになる。ここで、ブレーキペダル１の穴部１１の内周面のうちゴム部材８１と当接する部分は本発明の第１当接部１３に該当し、ピン部材３と直接当接する部分は本発明の第２当接部１４に相当する。   As shown in FIG. 2, when the occupant operates the brake pedal 1, the rubber member 81 and the brake pedal 1 come into contact with each other at the initial stage of the brake operation before the operation amount exceeds a predetermined value. The operating force is transmitted to the linking member 2 via the rubber member 81 (FIG. 2 (a)). When the operation is further continued, the rubber member 81 is elastically deformed and crushed, and the large diameter portion 32 of the pin member 3 and the inner peripheral surface of the hole portion 11 of the brake pedal 1 are in direct contact with each other. Is transmitted to the clevis 21 (linking member 2) (FIG. 2B). As described above, the brake pedal 1, the pin member 3, and the linkage member 2 are all prevented from coming into direct contact until the brake operation amount exceeds a predetermined value at the initial stage of the brake operation. The In the subsequent brake operation, when the brake operation amount exceeds a predetermined value, two members that sandwich the rubber member 81 come into contact with each other. Here, the portion of the inner peripheral surface of the hole 11 of the brake pedal 1 that contacts the rubber member 81 corresponds to the first contact portion 13 of the present invention, and the portion that directly contacts the pin member 3 corresponds to the first portion of the present invention. 2 corresponds to the contact portion 14.

上述のように、ブレーキ操作の初期においては、ピン部材３に巻き回したゴム部材８１を介してブレーキペダル１への操作力が連係部材２に伝達されることになる。このため、マスタシリンダ５の側で振動が発生した場合であっても、ゴム部材８１で振動を減衰することにより、振動がブレーキペダル１まで伝達されることを防止することができる。また、ゴム部材８１をピン部材３に巻き回すものであるから、装置の構成を簡便にできる上、装着等の取り扱いも容易であり、合理的なブレーキ装置を得ることができる。   As described above, in the initial stage of the brake operation, the operation force to the brake pedal 1 is transmitted to the linkage member 2 through the rubber member 81 wound around the pin member 3. For this reason, even when vibration is generated on the master cylinder 5 side, the vibration can be prevented from being transmitted to the brake pedal 1 by attenuating the vibration with the rubber member 81. Further, since the rubber member 81 is wound around the pin member 3, the configuration of the device can be simplified, and handling such as mounting is easy, and a rational brake device can be obtained.

［別実施形態］
（１）上述の実施形態においては、ブレーキペダル１の穴部１１のうち弾性部材８と当接する第２当接部１４の内径を大きくして、第１当接部１３を第２当接部１４よりもピン部材３の側に突出させても良い。特に、ピン部材３に小径部３１を形成せずにゴム部材８１を巻き回す場合は、ピン部材３からのゴム部材８１の突出量が大きくなるので、ブレーキペダル１の穴部１１をこのように形成すると良い。 [Another embodiment]
(1) In the above-described embodiment, the inner diameter of the second contact portion 14 that contacts the elastic member 8 in the hole portion 11 of the brake pedal 1 is increased, and the first contact portion 13 is changed to the second contact portion. You may make it protrude in the side of the pin member 3 rather than 14. In particular, when the rubber member 81 is wound around the pin member 3 without forming the small-diameter portion 31, the protrusion amount of the rubber member 81 from the pin member 3 increases, and thus the hole 11 of the brake pedal 1 is formed in this way. It is good to form.

（２）上述の実施形態では、ピン部材３にゴム部材８１を巻き回す例を説明したが、ブレーキペダル１の穴部１１の内側沿ってゴム部材８１を設けても良い。 (2) In the above-described embodiment, the example in which the rubber member 81 is wound around the pin member 3 has been described. However, the rubber member 81 may be provided along the inside of the hole portion 11 of the brake pedal 1.

（３）上述の実施形態では、弾性部材８として、ゴム部材８１を用いる場合を例に説明したが、弾性部材８としては、ばね部材などゴム部材以外の弾性部材を用いても良い。図３に示すように、この実施形態では、屈曲した板ばね部材８２がピン部材３とブレーキペダル１の穴部１１との間に介装されている。板ばね部材８２は、ピン部材３の小径部３１に嵌め込まれて固定されている。この実施形態でも、上述の実施形態と同様に、ブレーキ操作量が所定の操作量を超える前には、板ばね部材８２とブレーキペダル１とが当接してブレーキペダル１に対する操作力が板ばね部材８２を介してクレビス２１（連係部材２）に伝達される。その後、ブレーキ操作量が所定の操作量を超えた後に、板ばね部材８２が弾性変形して、ピン部材３の大径部３２とブレーキペダル１とが直接当接して、ブレーキペダル１に対する操作力が直接にクレビス２１（連係部材２）に伝達される。ここで、ブレーキペダル１の穴部１１の内周面のうち板ばね部材８２と当接する部分は本発明の第１当接部１３に該当し、ピン部材３と直接当接する部分は本発明の第２当接部１４に相当する。 (3) Although the case where the rubber member 81 is used as the elastic member 8 has been described as an example in the above-described embodiment, an elastic member other than the rubber member such as a spring member may be used as the elastic member 8. As shown in FIG. 3, in this embodiment, a bent leaf spring member 82 is interposed between the pin member 3 and the hole 11 of the brake pedal 1. The leaf spring member 82 is fitted and fixed to the small diameter portion 31 of the pin member 3. In this embodiment as well, the leaf spring member 82 and the brake pedal 1 are brought into contact with each other before the brake operation amount exceeds the predetermined operation amount, and the operation force on the brake pedal 1 is applied to the leaf spring member. It is transmitted to the clevis 21 (linking member 2) via 82. Thereafter, after the brake operation amount exceeds a predetermined operation amount, the leaf spring member 82 is elastically deformed, and the large diameter portion 32 of the pin member 3 and the brake pedal 1 are brought into direct contact with each other. Is directly transmitted to the clevis 21 (linking member 2). Here, the portion of the inner peripheral surface of the hole 11 of the brake pedal 1 that contacts the leaf spring member 82 corresponds to the first contact portion 13 of the present invention, and the portion that directly contacts the pin member 3 of the present invention. It corresponds to the second contact portion 14.

（４）図４に示す実施形態では、弾性部材８として、コイルばね８３を用いた例について説明する。この実施形態では、ブレーキペダルに穴部１１と垂直に連通する穴部１２が形成され穴部１２にコイルばね８３が介装されている。コイルばね８３は圧縮ばねでありその一端が穴部１２に形成されたストッパ１５に当接し、他端がピン部材３に当接している。この実施形態では、ブレーキ操作量が所定の操作量を超える前には、ブレーキペダル１に対する操作力がコイルばね８３を介してクレビス２１（連係部材２）に伝達される。その後、ブレーキ操作量が所定の操作量を超えた後には、コイルばね８３が圧縮されて、ピン部材３とブレーキペダル１とが直接当接して、ブレーキペダル１に対する操作力が直接にクレビス２１（連係部材２）に伝達される。 (4) In the embodiment shown in FIG. 4, an example in which a coil spring 83 is used as the elastic member 8 will be described. In this embodiment, the brake pedal is formed with a hole 12 that communicates perpendicularly with the hole 11, and a coil spring 83 is interposed in the hole 12. The coil spring 83 is a compression spring, one end of which is in contact with the stopper 15 formed in the hole portion 12 and the other end is in contact with the pin member 3. In this embodiment, before the brake operation amount exceeds a predetermined operation amount, the operation force applied to the brake pedal 1 is transmitted to the clevis 21 (linking member 2) via the coil spring 83. After that, after the brake operation amount exceeds a predetermined operation amount, the coil spring 83 is compressed, the pin member 3 and the brake pedal 1 are brought into direct contact, and the operation force on the brake pedal 1 is directly applied to the clevis 21 ( Is transmitted to the linking member 2).

（５）上述の実施形態では、ピン部材３とブレーキペダル１との間に弾性部材８を介装する例を説明したが、ピン部材３と連係部材２との間に弾性部材８を介装しても良い。この場合例えば、ピン部材３とクレビス２１の穴部２１との間に弾性部材８が介装される。 (5) In the above-described embodiment, the example in which the elastic member 8 is interposed between the pin member 3 and the brake pedal 1 has been described. However, the elastic member 8 is interposed between the pin member 3 and the linkage member 2. You may do it. In this case, for example, the elastic member 8 is interposed between the pin member 3 and the hole 21 of the clevis 21.
