JP 2002-178893 A JP 10-310035 A

ところで上記特許文献１、２に記載されたものは、車両の衝突時にクラッチペダルあるいはブレーキペダルの車体後方への移動を規制するためには、ペダルがドライバーの足から車体前方への反力を受けることが必要であり、そのためにドライバーの足に加わる荷重を充分に低減することができない可能性があった。   By the way, in Patent Documents 1 and 2, the pedal receives a reaction force from the driver's foot to the front of the vehicle in order to restrict the movement of the clutch pedal or the brake pedal to the rear of the vehicle in the event of a vehicle collision. Therefore, there is a possibility that the load applied to the driver's foot cannot be sufficiently reduced.

本発明は前述の事情に鑑みてなされたもので、車両の衝突時にペダルからドライバーの足に加わる荷重を低減することを目的とする。   The present invention has been made in view of the above-described circumstances, and an object thereof is to reduce a load applied from a pedal to a driver's foot when a vehicle collides.

上記目的を達成するために、請求項１に記載された発明によれば、ペダルにプッシュロッドを介して接続されて液圧を発生するマスタシリンダを、エンジン室および車室を仕切るダッシュパネルよりも車室側に配置した車両用ペダル装置において、ステアリングシャフトを車体に支持するステアリングハンガーの前方にマスタシリンダを配置し、車両の衝突時にダッシュパネルに押されて後退するマスタシリンダをステアリングハンガーに当接させて回転させることで、プッシュロッドを介してペダルを前方に移動させることを特徴とする車両用ペダル装置が提案される。   In order to achieve the above object, according to the invention described in claim 1, the master cylinder connected to the pedal via the push rod to generate the hydraulic pressure is provided more than the dash panel that partitions the engine compartment and the vehicle compartment. In a vehicle pedal device arranged on the passenger compartment side, a master cylinder is arranged in front of a steering hanger that supports the steering shaft on the vehicle body, and a master cylinder that is pushed back by a dash panel when the vehicle collides is brought into contact with the steering hanger. Thus, a pedal device for a vehicle is proposed in which the pedal is moved forward via a push rod by rotating the pedal.

また請求項２に記載された発明によれば、請求項１の構成に加えて、マスタシリンダを支持するマスタシリンダ支持ブラケットを、ペダルをダッシュパネルに支持するペダル支持ブラケットに固定し、マスタシリンダ支持ブラケットは、マスタシリンダがステアリングハンガーに当接した荷重で分離してペダル支持ブラケットとの連結を解除される分離部と、前記荷重で変形してマスタシリンダの回転を許容する脆弱部とを備えたことを特徴とする車両用ペダル装置が提案される。   According to the second aspect of the present invention, in addition to the configuration of the first aspect, the master cylinder support bracket that supports the master cylinder is fixed to the pedal support bracket that supports the pedal on the dash panel. The bracket includes a separation portion that is separated by a load that the master cylinder is in contact with the steering hanger and is disconnected from the pedal support bracket, and a weak portion that is deformed by the load and allows the rotation of the master cylinder. A vehicular pedal device is proposed.

尚、実施例のクラッチペダル２０は本発明のペダルに対応し、実施例のリベット２３は本発明の分離部に対応し、実施例の第１折り線Ｌ１は本発明の脆弱部に対応する。   In addition, the clutch pedal 20 of an Example respond | corresponds to the pedal of this invention, the rivet 23 of an Example respond | corresponds to the isolation | separation part of this invention, and the 1st folding line L1 of an Example respond | corresponds to the weak part of this invention.

請求項１の構成によれば、ステアリングシャフトを車体に支持するステアリングハンガーの前方にマスタシリンダを配置したので、車両の衝突時にダッシュパネルに押されて後退するマスタシリンダがステアリングハンガーに当接して回転すると、回転するマスタシリンダに接続されたプッシュロッドを介してペダルを前方に移動させることができる。このとき、ドライバーの足からペダルに反力を加える必要がなく、しかもペダルを積極的に前方に移動させることができるので、ペダルからドライバーの足に加わる荷重を一層効果的に低減することができる。   According to the configuration of the first aspect, since the master cylinder is disposed in front of the steering hanger that supports the steering shaft on the vehicle body, the master cylinder that is pushed back by the dash panel when the vehicle collides is in contact with the steering hanger and rotates. Then, the pedal can be moved forward via a push rod connected to the rotating master cylinder. At this time, there is no need to apply a reaction force to the pedal from the driver's foot, and the pedal can be actively moved forward, so the load applied to the driver's foot from the pedal can be more effectively reduced. .

請求項２の構成によれば、ペダル支持ブラケットに固定されたマスタシリンダ支持ブラケットが分離部と脆弱部とを備えているので、衝突の衝撃でマスタシリンダがステアリングハンガーに当接した荷重で分離部が分離してマスタシリンダ支持ブラケットとペダルブラケットとの連結を解除し、かつ前記荷重で脆弱部が変形してマスタシリンダの回転を許容することで、ペダルを前方に移動させることができる。   According to the configuration of the second aspect, since the master cylinder support bracket fixed to the pedal support bracket includes the separation portion and the weak portion, the separation portion is caused by the load that the master cylinder contacts the steering hanger due to the impact of the collision. Is separated to release the connection between the master cylinder support bracket and the pedal bracket, and the weak portion is deformed by the load to allow the master cylinder to rotate, thereby allowing the pedal to move forward.

以下、本発明の実施の形態を、添付の図面に示した本発明の実施例に基づいて説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on examples of the present invention shown in the accompanying drawings.

図１〜図４に示すように、自動車のエンジン室１１と車室１２とを仕切るダッシュパネル１３の後面（車室１２側の面）にペダル支持ブラケット１４が４本のボルト１５…で固定される。ペダル支持ブラケット１４は左右一対の側板１６，１７と、両側板１６，１７を後縁を左右方向に連結する連結板１８とを備えており、各々の側板１６，１７から前方に張り出す各２本の取付部１６ａ，１６ｂ；１７ａ，１７ｂが前記ボルト１５…でダッシュパネル１３に固定される。   As shown in FIGS. 1 to 4, a pedal support bracket 14 is fixed with four bolts 15 to the rear surface (surface on the vehicle compartment 12 side) of the dash panel 13 that partitions the engine compartment 11 and the vehicle compartment 12 of the automobile. The The pedal support bracket 14 includes a pair of left and right side plates 16, 17 and a connecting plate 18 that connects the side plates 16, 17 in the left-right direction. The mounting portions 16a, 16b; 17a, 17b of the book are fixed to the dash panel 13 with the bolts 15.

ペダル支持ブラケット１４の左右の側板１６，１７に跨がる支軸１９に、下端に踏面２０ａを備えたクラッチペダル２０のアーム部２０ｂの上部が前後揺動可能に枢支される。捩じりばねよりなるリターンスプリング２１の両端がペダル支持ブラケット１４の左側の側板１６およびクラッチペダル２０の前面上部に係止されており、このリターンスプリング２１の弾発力でクラッチペダル２０は最も後退した初期位置に向けて付勢される。ペダル支持ブラケット１４の左右の側板１６，１７の上部間にマスタシリンダ支持ブラケット２２が固定される。   An upper portion of the arm portion 20b of the clutch pedal 20 having a tread surface 20a at the lower end is pivotally supported by a support shaft 19 straddling the left and right side plates 16 and 17 of the pedal support bracket 14 so as to be swingable back and forth. Both ends of a return spring 21 made of a torsion spring are engaged with the left side plate 16 of the pedal support bracket 14 and the front upper portion of the clutch pedal 20, and the clutch pedal 20 is most retracted by the elastic force of the return spring 21. It is biased toward the initial position. A master cylinder support bracket 22 is fixed between upper portions of the left and right side plates 16 and 17 of the pedal support bracket 14.

図６および図７から明らかなように、マスタシリンダ支持ブラケット２２は所定形状に打ち抜かれた１枚の金属板を折り曲げて構成されるもので、中央の第１連結部２２ａおよび第２連結部２２ｂと、第１連結部２２ａの左右両側に延びる一対の第１固定部２２ｃ，２２ｃと、第２連結部２２ｂの左右両側に延びる一対の第２固定部２２ｄ，２２ｄとを備えており、第１連結部２２ａと第２連結部２２ｂとの間の第１折り線Ｌ１は「ヘ」字状に折り曲げられ、第１連結部２２ａと一対の第１固定部２２ｃ，２２ｃとの間の第２折り線Ｌ２，Ｌ２は９０°に折り曲げられ、第２連結部２２ｂと一対の第２固定部２２ｄ，２２ｄとの間の第３折り線Ｌ３，Ｌ３は９０°に折り曲げらる。第２連結部２２ｂにはマスタシリンダ２５との干渉を避けるためのＵ字状の切欠２２ｅが形成される。   As apparent from FIGS. 6 and 7, the master cylinder support bracket 22 is formed by bending a single metal plate punched into a predetermined shape, and has a first connecting portion 22a and a second connecting portion 22b in the center. And a pair of first fixing portions 22c, 22c extending on the left and right sides of the first connecting portion 22a, and a pair of second fixing portions 22d, 22d extending on the left and right sides of the second connecting portion 22b. The first fold line L1 between the connecting portion 22a and the second connecting portion 22b is bent in a “H” shape, and the second fold between the first connecting portion 22a and the pair of first fixing portions 22c and 22c. The lines L2 and L2 are bent at 90 °, and the third fold lines L3 and L3 between the second connecting portion 22b and the pair of second fixing portions 22d and 22d are bent at 90 °. A U-shaped notch 22e for avoiding interference with the master cylinder 25 is formed in the second connecting portion 22b.

図１〜図４に戻り、マスタシリンダ支持ブラケット２２は、その一対の第１固定部２２ｃ，２２ｃがペダル支持ブラケット１４の左右の側板１６，１７の上部内面に溶接Ｗ，Ｗで固定され、かつ一対の第２固定部２２ｄ，２２ｄがペダル支持ブラケット１４の左右の側板１６，１７の上部内面に所定の荷重で破断可能なリベット２３，２３で固定される。一対の第２固定部２２ｄ，２２ｄの内面にそれぞれステー２４，２４が固定されており、そこにマスタシリンダ２５の外周面に突設した一対のステー２６，２６が重ね合わされてボルト２７，２７およびナット２８，２８で締結される。これにより、概略円筒状のマスタシリンダ２５は、前下方に傾斜した状態で前端部分をマスタシリンダ支持ブラケット２２に固定される。マスタシリンダ２５から前下方に突出するプッシュロッド２９の前端に固定した二股のヨーク３０が、クラッチペダル２０のアーム部２０ｂの上部前端にピン３１で枢支される。   1 to 4, the master cylinder support bracket 22 has a pair of first fixing portions 22c and 22c fixed to the upper inner surfaces of the left and right side plates 16 and 17 of the pedal support bracket 14 by welding W and W, and The pair of second fixing portions 22d and 22d are fixed to the upper inner surfaces of the left and right side plates 16 and 17 of the pedal support bracket 14 with rivets 23 and 23 that can be broken by a predetermined load. Stays 24, 24 are fixed to the inner surfaces of the pair of second fixing portions 22d, 22d, respectively, and a pair of stays 26, 26 projecting from the outer peripheral surface of the master cylinder 25 are superposed on the bolts 27, 27 and Fastened with nuts 28, 28. Thereby, the substantially cylindrical master cylinder 25 is fixed to the master cylinder support bracket 22 at the front end portion in a state where the master cylinder 25 is inclined forward and downward. A bifurcated yoke 30 fixed to the front end of a push rod 29 protruding forward and downward from the master cylinder 25 is pivotally supported by a pin 31 on the upper front end of the arm portion 20 b of the clutch pedal 20.

クラッチペダル２０の支軸１９に固定した揺動部材３２の上下両端に第１、第２スイッチ作動部材３３，３４が設けられており、これら第１、第２スイッチ作動部材３３，３４により作動する第１、第２スイッチ３５，３６が連結板１８に設けられる。クラッチペダル２０が初期位置にあるときに第１スイッチ作動部材３３によって第１スイッチ３５がオンし、クラッチペダル２０が踏込位置にあるときに第２スイッチ作動部材３４によって第２スイッチ３６がオンし、これによりクラッチペダル２０の操作が検出される。   First and second switch actuating members 33 and 34 are provided at both upper and lower ends of a swing member 32 fixed to the support shaft 19 of the clutch pedal 20, and are actuated by the first and second switch actuating members 33 and 34. First and second switches 35 and 36 are provided on the connecting plate 18. When the clutch pedal 20 is in the initial position, the first switch 35 is turned on by the first switch operating member 33, and when the clutch pedal 20 is in the depressed position, the second switch 36 is turned on by the second switch operating member 34, Thereby, the operation of the clutch pedal 20 is detected.

図５から明らかなように、マスタシリンダ２５は、シリンダ本体３７と，シリンダ本体３７に摺動自在に嵌合するピストン３８とを備えており、プッシュロッド２９の端部に形成した凸状の球面２９ａとピストン３８の端部に形成した凹状の球面３８ａとが首振り可能に当接する。マスタシリンダ２５が上記取付状態にあるとき、ステアリングシャフトを車体に支持するために車体左右方向に配置された強度部材であるステアリングハンガー３９の前方に、前下方に向けて傾斜するマスタシリンダ２５の後端部が当接可能に対向する。   As is clear from FIG. 5, the master cylinder 25 includes a cylinder body 37 and a piston 38 that is slidably fitted to the cylinder body 37, and has a convex spherical surface formed at the end of the push rod 29. 29a and a concave spherical surface 38a formed at the end of the piston 38 come into contact with each other so as to be able to swing. When the master cylinder 25 is in the mounted state, the rear of the master cylinder 25 is inclined forward and downward in front of the steering hanger 39, which is a strength member disposed in the lateral direction of the vehicle body to support the steering shaft on the vehicle body. The end portions face each other so that they can come into contact with each other.

次に、上記構成を備えた本発明の実施例の作用を説明する。   Next, the operation of the embodiment of the present invention having the above configuration will be described.

ドライバーがクラッチペダル２０の踏面２０ａを踏むと、アーム部２０ｂがリターンスプリング２１の弾発力に抗して支軸１９まわりに揺動し、ピン３１およびヨーク３０を介してプッシュロッド２９を後上方に押圧することで、マスタシリンダ２５のピストン３８がシリンダ本体３７内に押し込まれてクラッチの締結を解除する油圧が発生する。このとき、プッシュロッド２９の球面２９ａとピストン３８の球面３８ａとが首振り可能に当接することで、プッシュロッド２９のコジリが防止される。   When the driver steps on the tread surface 20 a of the clutch pedal 20, the arm portion 20 b swings around the support shaft 19 against the elastic force of the return spring 21, and pushes the push rod 29 rearward and upward via the pin 31 and the yoke 30. The piston 38 of the master cylinder 25 is pushed into the cylinder main body 37 and the hydraulic pressure is released to release the clutch. At this time, the spherical surface 29a of the push rod 29 and the spherical surface 38a of the piston 38 come into contact with each other so as to be able to swing, thereby preventing the push rod 29 from being twisted.

車両が衝突してダッシュパネル１３が図９の鎖線位置から実線位置へと後退すると、ダッシュパネル１３に支持されたマスタシリンダ２５も一体に後退し、その後部下面がステアリングハンガー３９に当接する。その結果、マスタシリンダ２５が後端を前上方に押し上げられることで、マスタシリンダ支持ブラケット２２の第２固定部２２ｄ，２２ｄに設けたリベット２３，２３が破断し（図８〜図１０参照）、マスタシリンダ２５がボルト２７，２７およびナット２８，２８で固定された第２固定部２２ｄ，２２ｄおよび第２連結部２２ｂが第１連結部２２ａに対して第１折り線Ｌ１まわりに折れ曲がり、マスタシリンダ２５が鉛直姿勢に起立する（図９および図１０の矢印Ａ参照）。   When the vehicle collides and the dash panel 13 retreats from the chain line position of FIG. 9 to the solid line position, the master cylinder 25 supported by the dash panel 13 also retreats integrally, and the lower surface of the rear part comes into contact with the steering hanger 39. As a result, when the master cylinder 25 is pushed up at the rear end, the rivets 23 and 23 provided on the second fixing portions 22d and 22d of the master cylinder support bracket 22 are broken (see FIGS. 8 to 10). The second fixing portions 22d and 22d and the second connecting portion 22b, to which the master cylinder 25 is fixed by bolts 27 and 27 and nuts 28 and 28, are bent around the first fold line L1 with respect to the first connecting portion 22a. 25 stands upright (see arrow A in FIGS. 9 and 10).

その結果、プッシュロッド２９が図９および図１０の矢印Ｂ方向に引き上げられることで、クラッチペダル２０は支軸１９を中心として図９および図１０矢印Ｃ方向に揺動する。その結果、クラッチペダル２０の踏面２０ａはドライバーの足から離れるように車体前方に移動し、ドライバーの足に荷重が加わるのを防止することができる。特に、クラッチペダル２０は踏面２０ａがドライバーの足から受ける反力で車体前方に移動するのではなく、ドライバーの足とは無関係にマスタシリンダ２５の回転によって車体前方に移動するので、ドライバーの足に荷重が加わるのを一層確実に防止することができる。   As a result, when the push rod 29 is pulled up in the direction of arrow B in FIGS. 9 and 10, the clutch pedal 20 swings about the support shaft 19 in the direction of arrow C in FIGS. 9 and 10. As a result, the tread surface 20a of the clutch pedal 20 moves to the front of the vehicle body away from the driver's foot, and it is possible to prevent a load from being applied to the driver's foot. In particular, the clutch pedal 20 is not moved forward by the reaction force received by the tread 20a from the driver's foot, but is moved forward by the rotation of the master cylinder 25 regardless of the driver's foot. It can prevent more reliably that a load is added.

以上、本発明の実施例を説明したが、本発明はその要旨を逸脱しない範囲で種々の設計変更を行うことが可能である。   The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

例えば、実施例ではクラッチペダル２０を例示したが、本発明はブレーキペダルに対しても適用することができる。   For example, although the clutch pedal 20 is illustrated in the embodiment, the present invention can also be applied to a brake pedal.

また本発明の破断部は実施例のリベット２３，２３に限定されず、シヤピンのような荷重の入力によって破断する任意の手段を採用することができる。   Further, the breaking portion of the present invention is not limited to the rivets 23 and 23 of the embodiment, and any means for breaking by inputting a load such as a shear pin can be adopted.

また本発明の脆弱部は実施例のシリンダ支持ブラケット２２の第１折り線Ｌ１に限定されず、ヒンジのような容易に屈曲可能な任意の手段を採用することができる。   Moreover, the weak part of this invention is not limited to the 1st fold line L1 of the cylinder support bracket 22 of an Example, The arbitrary means which can be bent easily like a hinge can be employ | adopted.
