Description

車両のペダル装置vehicle pedal device
　本開示は、車両のペダル装置に関する。 The present disclosure relates to a pedal device for a vehicle.
　車両のペダル装置は、ペダルアームと、伸縮装置と、リンク機構と、を備えている。
　ペダルアームは、ペダル固定軸から上方に向けて延びている。ペダルアームは、車両の運転者による踏み込み操作に伴ってペダル固定軸の中心軸線周りに回転する。 A vehicle pedal device includes a pedal arm, a telescoping device, and a link mechanism.
The pedal arm extends upward from the pedal fixing shaft. The pedal arm rotates around the center axis of the pedal fixing shaft as the driver of the vehicle depresses the pedal.
　伸縮装置は、ペダルアームよりも車両の前方側に位置している。伸縮装置は、上下方向に伸縮することが可能となっている。伸縮装置としては、車両のブレーキ装置に対し同装置を作動させるための油圧を付与するマスタシリンダ、及び、運転者が前記ペダルアームを踏み込んだとき、同ペダルアームに対し反力を付与する反力装置等があげられる。 The telescoping device is located further forward of the vehicle than the pedal arm. The expansion and contraction device is capable of expanding and contracting in the vertical direction. The expansion and contraction device includes a master cylinder that applies hydraulic pressure to the brake device of the vehicle to operate the device, and a reaction force that applies a reaction force to the pedal arm when the driver depresses the pedal arm. Examples include equipment.
　リンク機構は、ペダルアームと伸縮装置とに連結されている。リンク機構は、運転者の踏み込み操作によってペダルアームがペダル固定軸の中心軸線周りに回転したとき、そのペダルアームの回転運動を伸縮装置の伸縮運動に変換するものである。 The link mechanism is connected to the pedal arm and the telescoping device. The link mechanism converts the rotational movement of the pedal arm into the telescopic movement of the telescoping device when the pedal arm rotates around the central axis of the pedal fixing shaft due to a pedal operation by the driver.
　上記リンク機構としては、例えば特許文献１に示すものが知られている。特許文献１に開示されているリンク機構は、連結リンクと、中心軸と、補助リンクと、を備えている。
　連結リンクは、ペダルアームと伸縮装置との間に配置されている。連結リンクは、車両に固定された中心軸の中心軸線周りに回転可能となっている。連結リンクの第１端部は伸縮装置に連結されており、連結リンクの第２端部は補助リンクを介してペダルアームに連結されている。 As the above-mentioned link mechanism, for example, one shown in Patent Document 1 is known. The link mechanism disclosed in Patent Document 1 includes a connecting link, a central shaft, and an auxiliary link.
A connecting link is arranged between the pedal arm and the telescoping device. The connecting link is rotatable around a central axis of a central shaft fixed to the vehicle. A first end of the connecting link is connected to the telescoping device, and a second end of the connecting link is connected to the pedal arm via an auxiliary link.
　車両の運転者がペダルアームを踏み込むと、ペダルアームのペダル固定軸の中心軸線周りの回転運動が、補助リンクを介して連結リンクの中心軸の中心軸線周りの回転運動に変換される。このように回転運動する連結リンクによって伸縮装置が縮められる。 When the driver of the vehicle depresses the pedal arm, the rotational movement around the central axis of the pedal fixing shaft of the pedal arm is converted to the rotational movement around the central axis of the connecting link via the auxiliary link. The telescoping device is retracted by the connecting link that rotates in this manner.

　上下方向に伸縮する伸縮装置がペダルアームの前方に配置される場合、ペダルアームの踏み込み（回転）によって伸縮装置を必要量縮めるためには、リンク機構を大型化しなければならなくなる。 If a telescoping device that expands and contracts in the vertical direction is placed in front of the pedal arm, the link mechanism must be made larger in order to retract the telescoping device by the necessary amount by stepping on (rotating) the pedal arm.
　詳しくは、中心軸の中心軸線周りに回転する連結リンクを大きくすることにより、伸縮装置と繋がる連結リンクの第１端部を回転軸から大きく離すとともに、補助リンクを介してペダルアームと繋がる連結リンクの第２端部を回転軸から大きく離す必要がある。更に、連結リンクとペダルアームとの間に補助アームを介在させる必要がある。これらの構成を採用することにより、ペダルアームの回転運動が効率よく伸縮装置の伸縮運動に変換される。その結果、上下方向に伸縮する伸縮装置がペダルアームの前方に配置される場合であっても、ペダルアームの踏み込み（回転）によって上記伸縮装置を必要量縮められるようになる。 Specifically, by increasing the size of the connecting link that rotates around the central axis of the central axis, the first end of the connecting link that connects to the telescoping device is separated from the rotating shaft by a large distance, and the connecting link that connects to the pedal arm via the auxiliary link It is necessary to separate the second end of the rotary shaft from the rotation axis by a large distance. Furthermore, it is necessary to interpose an auxiliary arm between the connecting link and the pedal arm. By employing these configurations, the rotational motion of the pedal arm is efficiently converted into the telescopic motion of the telescoping device. As a result, even if the telescoping device that expands and contracts in the vertical direction is arranged in front of the pedal arm, the telescoping device can be retracted by the necessary amount by pressing (rotating) the pedal arm.
　ただし、上述した構成の採用によってリンク機構が車両の前後方向に大型化する。このため、ペダル装置の設置スペースの確保が困難になる。 However, by adopting the above-described configuration, the link mechanism becomes larger in the longitudinal direction of the vehicle. This makes it difficult to secure an installation space for the pedal device.
　本開示の一態様に係る車両のペダル装置は、ペダルアームと、伸縮装置と、リンク機構と、を備える。ペダルアームは、ペダル固定軸から上方に向けて延びており、車両の運転者による踏み込み操作に伴ってペダル固定軸線の中心線周りに回転するように構成される。伸縮装置は、ペダルアームよりも車両の前方側に位置し、上下方向に伸縮するように構成される。リンク機構は、ペダルアームと伸縮装置とに連結され、運転者の踏み込み操作によってペダルアームがペダル固定軸の中心軸線周りに回転したとき、そのペダルアームの回転運動を伸縮装置の伸縮運動に変換するように構成される。上記リンク機構は、連結リンクと、回転レバーと、を備える。連結リンクは、ペダルアームと前記伸縮装置とを繋ぐようにペダルアームと伸縮装置との間で延びている。連結リンクは、連結リンクの長手方向において第１端部と第２端部とを有する。第１端部は、ペダル固定軸と平行な中心軸線を有する第１ピンを介してペダルアームに対し連結され、それにより、第１ピンの中心軸線周りに回転するように構成される。第２端部は、ペダル固定軸と平行な中心軸線を有する第２ピンを介して伸縮装置に対し連結され、それにより、第２ピンの中心軸線周りに回転するように構成される。回転レバーは、ペダル固定軸と平行なレバー固定軸から上方に向けて延び、前記レバー固定軸の中心軸線周りに回転するように構成される。回転レバーの上端部は、ペダル固定軸と平行な中心軸線を有する第３ピンを介して連結リンクにおける第１及び第２端部の間に連結され、それにより、第３ピンの中心軸線周りに回転するように構成される。 A pedal device for a vehicle according to one aspect of the present disclosure includes a pedal arm, a telescoping device, and a link mechanism. The pedal arm extends upward from the pedal fixing axis, and is configured to rotate around the center line of the pedal fixing axis as the driver of the vehicle depresses the pedal. The expansion and contraction device is located on the front side of the vehicle rather than the pedal arm, and is configured to expand and contract in the vertical direction. The link mechanism is connected to the pedal arm and the telescoping device, and when the pedal arm rotates around the central axis of the pedal fixing shaft due to the driver's depression operation, the link mechanism converts the rotational motion of the pedal arm into the telescoping motion of the telescoping device. It is configured as follows. The link mechanism includes a connecting link and a rotating lever. A connecting link extends between the pedal arm and the telescoping device to connect the pedal arm and the telescoping device. The connecting link has a first end and a second end in the longitudinal direction of the connecting link. The first end is coupled to the pedal arm via a first pin having a central axis parallel to the pedal fixation axis, and is thereby configured to rotate about the central axis of the first pin. The second end is connected to the telescoping device via a second pin having a central axis parallel to the pedal fixation axis and is thereby configured to rotate about the central axis of the second pin. The rotating lever extends upward from a lever fixing shaft parallel to the pedal fixing shaft, and is configured to rotate around the central axis of the lever fixing shaft. The upper end of the rotating lever is connected between the first and second ends of the connecting link via a third pin having a central axis parallel to the pedal fixing axis, so that configured to rotate.

　　［第１実施形態］
　以下、車両のペダル装置の第１実施形態について図１及び図２を参照して説明する。
　図１及び図２に示すように、車両のペダル装置は、ペダルアーム１１と、伸縮装置１２と、リンク機構１３と、を備えている。 [First embodiment]
Hereinafter, a first embodiment of a pedal device for a vehicle will be described with reference to FIGS. 1 and 2.
As shown in FIGS. 1 and 2, the vehicle pedal device includes a pedal arm 11, a telescoping device 12, and a link mechanism 13.
　ペダルアーム１１は、車両に固定されたペダル固定軸１４から上方に向けて延びている。ペダルアーム１１は、車両の運転者による踏み込み操作に伴って、ペダル固定軸１４の中心軸線周りに回転する。図１は、ペダルアーム１１が踏み込まれていないときのペダル装置を示している。図２は、ペダルアーム１１が踏み込まれているときのペダル装置を示している。 The pedal arm 11 extends upward from a pedal fixing shaft 14 fixed to the vehicle. The pedal arm 11 rotates around the central axis of the pedal fixing shaft 14 as the driver of the vehicle depresses the pedal. FIG. 1 shows the pedal device when the pedal arm 11 is not depressed. FIG. 2 shows the pedal device when the pedal arm 11 is depressed.
　伸縮装置１２は、ペダルアーム１１よりも車両の前方側、すなわち図１の左側に位置している。伸縮装置１２は、車両に対し固定されているとともに、上下方向に伸縮することが可能となっている。ここで言う上下方向とは、水平面に対し垂直な方向だけでなく、その垂直な方向に対しある程度傾斜した方向も含む。 The telescoping device 12 is located on the front side of the vehicle relative to the pedal arm 11, that is, on the left side in FIG. The expansion/contraction device 12 is fixed to the vehicle and can be expanded/contracted in the vertical direction. The vertical direction mentioned here includes not only a direction perpendicular to a horizontal plane but also a direction inclined to some extent with respect to the perpendicular direction.
　伸縮装置１２は、その長手方向が図２に示される状態のペダルアーム１１の長手方向とほぼ一致するように配置されている。ペダルアーム１１に対して車両の前方側には車両が有する他の部品、例えば衝突補強材１５が配置されている。ペダルアーム１１の上方には、運転者がペダルアーム１１を踏み込む際の足の動きを許容するためのワークスペースを確保する必要がある。伸縮装置１２は、上記衝突補強材１５との干渉を避けること、及び、上記ワークスペースを確保することを目的として、上述したように配置される。 The telescopic device 12 is arranged so that its longitudinal direction substantially coincides with the longitudinal direction of the pedal arm 11 in the state shown in FIG. Other parts of the vehicle, such as a collision reinforcement member 15, are arranged on the front side of the vehicle with respect to the pedal arm 11. It is necessary to secure a work space above the pedal arm 11 to allow the driver to move his or her feet when stepping on the pedal arm 11. The expansion and contraction device 12 is arranged as described above for the purpose of avoiding interference with the collision reinforcement member 15 and securing the work space.
　伸縮装置１２としては、車両のブレーキ装置に対し同装置を作動させるための油圧を付与するマスタシリンダ、及び、運転者が前記ペダルアーム１１を踏み込んだとき、同ペダルアーム１１に対し反力を付与する反力装置等があげられる。この実施形態ではマスタシリンダが伸縮装置１２として用いられている。 The telescoping device 12 includes a master cylinder that applies hydraulic pressure to the brake device of the vehicle to operate the device, and a master cylinder that applies a reaction force to the pedal arm 11 when the driver depresses the pedal arm 11. Examples include reaction force devices. In this embodiment, a master cylinder is used as the telescoping device 12.
　リンク機構１３は、ペダルアーム１１と伸縮装置１２とに連結されている。リンク機構１３は、運転者の踏み込み操作によってペダルアーム１１がペダル固定軸１４の中心軸線周りに回転したとき、そのペダルアーム１１の回転運動を伸縮装置１２の伸縮運動に変換する。以下、リンク機構１３の構造について詳しく述べる。 The link mechanism 13 is connected to the pedal arm 11 and the telescoping device 12. When the pedal arm 11 rotates around the central axis of the pedal fixing shaft 14 due to the driver's depression operation, the link mechanism 13 converts the rotational movement of the pedal arm 11 into an elastic movement of the extension/retraction device 12 . The structure of the link mechanism 13 will be described in detail below.
　＜リンク機構１３の構造＞
　リンク機構１３は、連結リンク１６と、回転レバー２０と、を備えている。
　連結リンク１６は、ペダルアーム１１と伸縮装置１２とを繋ぐようにペダルアーム１１と伸縮装置１２との間で延びている。連結リンク１６における長手方向の第１端部は、ペダル固定軸１４と平行な中心軸線を有する第１ピン１８を介してペダルアーム１１に対し連結されている。第１ピン１８は、ペダル固定軸１４よりも上側に位置している。連結リンク１６の第１端部は、第１ピン１８の中心軸線周りに回転することが可能となっている。 <Structure of link mechanism 13>
The link mechanism 13 includes a connecting link 16 and a rotating lever 20.
The connecting link 16 extends between the pedal arm 11 and the telescoping device 12 so as to connect the pedal arm 11 and the telescoping device 12. A first longitudinal end of the connecting link 16 is connected to the pedal arm 11 via a first pin 18 having a central axis parallel to the pedal fixing shaft 14 . The first pin 18 is located above the pedal fixing shaft 14. The first end of the connecting link 16 is rotatable around the central axis of the first pin 18 .
　連結リンク１６における長手方向の第２端部は、ペダル固定軸１４と平行な中心軸線を有する第２ピン１９を介して伸縮装置１２に対し連結されている。第２ピン１９は、伸縮装置１２の下端部に位置している。この下端部の上下動によって伸縮装置１２が伸縮する。連結リンク１６の第２端部は、第２ピン１９の中心軸線周りに回転することが可能となっている。 The second end of the connecting link 16 in the longitudinal direction is connected to the telescoping device 12 via a second pin 19 having a central axis parallel to the pedal fixing shaft 14. The second pin 19 is located at the lower end of the telescoping device 12 . The expansion and contraction device 12 expands and contracts by this vertical movement of the lower end. The second end of the connecting link 16 can rotate around the central axis of the second pin 19.
　回転レバー２０は、ペダルアーム１１と伸縮装置１２との間で上下方向に延びるように配置されている。ここで言う上下方向とは、水平面に対し垂直な方向だけでなく、その垂直な方向に対しある程度傾斜した方向も含む。 The rotating lever 20 is arranged to extend in the vertical direction between the pedal arm 11 and the telescoping device 12. The vertical direction mentioned here includes not only a direction perpendicular to a horizontal plane but also a direction inclined to some extent with respect to the perpendicular direction.
　回転レバー２０の下端部は、ペダル固定軸１４と平行なレバー固定軸２１に固定されている。レバー固定軸２１は、ペダル固定軸１４よりも車両の前方側（図１の左側）に位置している。レバー固定軸２１は車両に固定されている。回転レバー２０は、レバー固定軸２１から上方に向けて延び、レバー固定軸２１の中心軸線周りに回転することが可能となっている。 The lower end of the rotating lever 20 is fixed to a lever fixing shaft 21 parallel to the pedal fixing shaft 14. The lever fixing shaft 21 is located further forward of the vehicle (on the left side in FIG. 1) than the pedal fixing shaft 14. The lever fixing shaft 21 is fixed to the vehicle. The rotating lever 20 extends upward from the lever fixing shaft 21 and can rotate around the central axis of the lever fixing shaft 21.
　回転レバー２０の上端部は、ペダル固定軸１４と平行な中心軸線を有する第３ピン２２を介して、連結リンク１６における第１及び第２端部の間の部分に連結されている。回転レバー２０の上端部は、第３ピン２２の中心軸線周りに回転することが可能となっている。 The upper end of the rotating lever 20 is connected to a portion of the connecting link 16 between the first and second ends via a third pin 22 having a central axis parallel to the pedal fixing shaft 14. The upper end of the rotary lever 20 can rotate around the central axis of the third pin 22.
　次に、本実施形態における車両のペダル装置の作用効果について説明する。
　（１－１）車両の運転者が図１に示すペダルアーム１１を踏み込むと、図１の矢印Ｙ１で示すようにペダルアーム１１がペダル固定軸１４の中心軸線周りに回転する。このペダルアーム１１の回転に伴い、同ペダルアーム１１と連結リンク１６を介して繋がる回転レバー２０も、レバー固定軸２１の中心軸線周りに図１の矢印Ｙ２で示すように回転する。 Next, the effects of the vehicle pedal device in this embodiment will be explained.
(1-1) When the driver of the vehicle depresses the pedal arm 11 shown in FIG. 1, the pedal arm 11 rotates around the central axis of the pedal fixing shaft 14 as shown by arrow Y1 in FIG. As the pedal arm 11 rotates, the rotating lever 20 connected to the pedal arm 11 via the connecting link 16 also rotates around the central axis of the lever fixing shaft 21 as shown by arrow Y2 in FIG.
　そして、このように回転する回転レバー２０の連結リンク１６との連結箇所が伸縮装置１２に向けて移動する。更に、ペダルアーム１１と共に移動する連結リンク１６が第３ピン２２の中心軸線周りに図１の矢印Ｙ３で示すように回転する。これにより、図２に示すように、連結リンク１６における伸縮装置１２の下端部に繋がる箇所が上方に移動することによって、伸縮装置１２を上方に向けて収縮させる。上述した回転レバー２０及び連結リンク１６の動きにより、伸縮装置１２を必要量縮めることができる。 Then, the connection point of the rotating lever 20 that rotates in this way with the connecting link 16 moves toward the telescopic device 12. Furthermore, the connecting link 16 that moves together with the pedal arm 11 rotates around the central axis of the third pin 22 as shown by arrow Y3 in FIG. As a result, as shown in FIG. 2, the portion of the connecting link 16 connected to the lower end of the telescopic device 12 moves upward, thereby causing the telescopic device 12 to contract upward. The movement of the rotary lever 20 and the connecting link 16 described above allows the telescoping device 12 to be retracted by the required amount.
　このように伸縮装置１２を必要量縮めるために、従来のように連結リンクを大きくしたり、連結リンクとペダルアーム１１との間に補助リンクを介在させたりしなくてもよい。そのため、リンク機構１３が車両の前後方向に大型化することを抑制できる。その結果、ペダル装置の設置スペースを容易に確保することができる。 In order to contract the telescopic device 12 by the necessary amount in this way, there is no need to make the connecting link larger or to interpose an auxiliary link between the connecting link and the pedal arm 11 as in the conventional art. Therefore, it is possible to suppress the link mechanism 13 from increasing in size in the longitudinal direction of the vehicle. As a result, installation space for the pedal device can be easily secured.
　　［第２実施形態］
　次に、車両のペダル装置の第２実施形態について図３Ａ～図６を参照して説明する。第１実施形態と同一の構成については、第１実施形態と同一の符号を付して詳細な説明を省略する。 [Second embodiment]
Next, a second embodiment of a pedal device for a vehicle will be described with reference to FIGS. 3A to 6. The same components as in the first embodiment are given the same reference numerals as in the first embodiment, and detailed description thereof will be omitted.
　図３Ａ及び図４Ａに示す本実施形態のペダル装置は、伸縮装置１２として用いられる反力装置を備えており、その伸縮装置１２とは別にマスタシリンダ３１を備えている。マスタシリンダ３１は、リンク機構１３の下側に位置している。マスタシリンダ３１は、車両に対し固定されているとともに、車両の前後方向（図３Ａの左右方向）に伸縮することが可能となっている。マスタシリンダ３１は、ペダルアーム１１に連結される先端部（図３Ａの右端部）を有しており、運転者によるペダルアーム１１の踏み込み操作に伴って収縮する。マスタシリンダ３１は、ペダルアーム１１の踏み込み操作の解除に伴って伸長する。 The pedal device of this embodiment shown in FIGS. 3A and 4A includes a reaction force device used as a telescoping device 12, and is provided with a master cylinder 31 separately from the telescoping device 12. The master cylinder 31 is located below the link mechanism 13. The master cylinder 31 is fixed to the vehicle and can expand and contract in the longitudinal direction of the vehicle (the left-right direction in FIG. 3A). The master cylinder 31 has a tip (right end in FIG. 3A) connected to the pedal arm 11, and contracts as the driver depresses the pedal arm 11. The master cylinder 31 extends as the pedal arm 11 is released from the depression operation.
　このペダル装置が搭載される車両は、ブレーキ装置をバイワイヤ動作モードとバイワイヤ非動作モードとのいずれかの動作モードで動作させる。バイワイヤ動作モードでは、運転者がペダルアーム１１を踏み込んだときのペダルアーム１１の操作量がセンサによって検出される。そして、検出された上記操作量に基づきブレーキ装置が動作される。バイワイヤ動作モードでのマスタシリンダ３１は、ペダルアーム１１の踏み込み操作に伴う収縮時、ブレーキ装置に対する油圧の付与を行わない。このため、バイワイヤ動作モードのときにペダルアーム１１を踏み込んでも、マスタシリンダ３１からの反力がペダルアーム１１に作用することはない。 A vehicle equipped with this pedal device operates the brake device in either a by-wire operation mode or a by-wire non-operation mode. In the by-wire operation mode, the amount of operation of the pedal arm 11 when the driver depresses the pedal arm 11 is detected by a sensor. Then, the brake device is operated based on the detected operation amount. In the by-wire operation mode, the master cylinder 31 does not apply hydraulic pressure to the brake device when the pedal arm 11 is contracted due to a depression operation. Therefore, even if the pedal arm 11 is depressed in the by-wire operation mode, no reaction force from the master cylinder 31 will act on the pedal arm 11.
　ペダルアーム１１の操作量を検出する上記センサの故障時等には、車両はブレーキ装置をバイワイヤ非動作モードで動作させる。バイワイヤ非動作モードでは、マスタシリンダ３１は、その収縮に伴いブレーキ装置に対する油圧の付与を行って同ブレーキ装置を動作させる。従って、バイワイヤ非動作モードでは、運転者がペダルアーム１１を踏み込んだとき、マスタシリンダ３１が収縮することに伴ってブレーキ装置に対し油圧が付与される。そして、その付与された油圧によりブレーキ装置が動作される。このため、バイワイヤ非動作モードのときにペダルアーム１１が踏み込まれると、マスタシリンダ３１からの反力がペダルアーム１１に作用する。 When the sensor that detects the amount of operation of the pedal arm 11 fails, the vehicle operates the brake system in a by-wire non-operation mode. In the by-wire non-operation mode, the master cylinder 31 applies hydraulic pressure to the brake device as it contracts to operate the brake device. Therefore, in the by-wire non-operation mode, when the driver depresses the pedal arm 11, the master cylinder 31 contracts and hydraulic pressure is applied to the brake device. Then, the brake device is operated by the applied hydraulic pressure. Therefore, when the pedal arm 11 is depressed in the by-wire non-operation mode, a reaction force from the master cylinder 31 acts on the pedal arm 11.
　ペダル装置は、切換機構３２を備えている。切換機構３２は、バイワイヤ動作モード時には、反力装置である上記伸縮装置１２からの反力をペダルアーム１１に作用させる。切換機構３２は、バイワイヤ非動作モード時には、上記伸縮装置１２からペダルアーム１１への上記反力の伝達を遮断する。このため、バイワイヤ非動作モード時、ペダルアーム１１にマスタシリンダ３１からの反力に加えて、伸縮装置１２からの反力も作用するということを回避できる。 The pedal device includes a switching mechanism 32. The switching mechanism 32 applies a reaction force from the expansion and contraction device 12, which is a reaction force device, to the pedal arm 11 in the by-wire operation mode. The switching mechanism 32 interrupts transmission of the reaction force from the telescoping device 12 to the pedal arm 11 during the by-wire non-operation mode. Therefore, in the by-wire non-operation mode, it is possible to avoid the fact that in addition to the reaction force from the master cylinder 31, the reaction force from the expansion and contraction device 12 acts on the pedal arm 11.
　＜切換機構３２の構造＞
　切換機構３２は、切換ブラケット３３と、カラー３４と、を備えている。切換ブラケット３３は、ペダルアーム１１に沿って延びるように配置されている。切換ブラケット３３における長手方向の両端部の間の箇所は、第４ピン３５を介してペダルアーム１１に連結されている。第４ピン３５は、第１ピン１８とペダル固定軸１４との間に位置している。切換ブラケット３３は、ペダルアーム１１に対し第４ピン３５の中心軸線周りに相対回転することが可能となっている。 <Structure of switching mechanism 32>
The switching mechanism 32 includes a switching bracket 33 and a collar 34. The switching bracket 33 is arranged to extend along the pedal arm 11. A portion of the switching bracket 33 between both ends in the longitudinal direction is connected to the pedal arm 11 via a fourth pin 35. The fourth pin 35 is located between the first pin 18 and the pedal fixing shaft 14. The switching bracket 33 can rotate relative to the pedal arm 11 around the central axis of the fourth pin 35.
　第１ピン１８は、図３Ａに示す連結位置Ｐ１と図４Ａに示す非連結位置Ｐ２との間で、移動することが可能となっている。第１ピン１８は、反力装置である上記伸縮装置１２からの反力を受けて、上記連結位置Ｐ１に保持される。図５は、図３Ａ中の符号５で示される円によって囲んだ部分を拡大して示している。図６は、図４Ａ中の符号６で示される円によって囲んだ部分を拡大して示している。 The first pin 18 is movable between a connected position P1 shown in FIG. 3A and a non-connected position P2 shown in FIG. 4A. The first pin 18 receives a reaction force from the expansion and contraction device 12, which is a reaction force device, and is held at the connection position P1. FIG. 5 shows an enlarged view of the portion surrounded by the circle indicated by the reference numeral 5 in FIG. 3A. FIG. 6 shows an enlarged view of a portion surrounded by a circle indicated by the reference numeral 6 in FIG. 4A.
　図５に示すように、ペダルアーム１１には凹部３６が形成されている。凹部３６は、車両の前方、すなわち図５の左方に向けて開口している。凹部３６には第１ピン１８が収容されている。第１ピン１８は、伸縮装置１２（図３Ａ）からの反力を受けて凹部３６の内壁に押し付けられることにより、連結位置Ｐ１に保持される。第１ピン１８は、連結位置Ｐ１に保持されることにより、ペダルアーム１１に対し連結される。この状態においては、伸縮装置１２からの反力が、リンク機構１３の第１ピン１８を介してペダルアーム１１に作用する。連結位置Ｐ１に保持された第１ピン１８には、図５に示すように切換ブラケット３３の上端部が当接している。 As shown in FIG. 5, a recess 36 is formed in the pedal arm 11. The recess 36 opens toward the front of the vehicle, that is, toward the left in FIG. 5 . The first pin 18 is housed in the recess 36 . The first pin 18 is held at the connection position P1 by being pressed against the inner wall of the recess 36 in response to a reaction force from the expansion and contraction device 12 (FIG. 3A). The first pin 18 is connected to the pedal arm 11 by being held at the connection position P1. In this state, a reaction force from the telescoping device 12 acts on the pedal arm 11 via the first pin 18 of the link mechanism 13. As shown in FIG. 5, the upper end of the switching bracket 33 is in contact with the first pin 18 held at the connection position P1.
　図３Ａに示すように、切換機構３２のカラー３４は、マスタシリンダ３１、ペダルアーム１１、及び、切換ブラケット３３の下端部と連結されている。詳しくは、カラー３４は、マスタシリンダ３１における先端部、すなわちマスタシリンダ３１の図３Ａにおける右端部に固定されている。カラー３４の中心軸線は、ペダル固定軸１４と平行になっている。マスタシリンダ３１の上記先端部は、カラー３４を介して、切換ブラケット３３の下端部と連結されている。切換ブラケット３３の下端部は、カラー３４に対し、カラー３４の中心軸線周りに相対回転することが可能となっている。 As shown in FIG. 3A, the collar 34 of the switching mechanism 32 is connected to the master cylinder 31, the pedal arm 11, and the lower end of the switching bracket 33. Specifically, the collar 34 is fixed to the tip of the master cylinder 31, that is, to the right end of the master cylinder 31 in FIG. 3A. The center axis of the collar 34 is parallel to the pedal fixing shaft 14. The tip of the master cylinder 31 is connected to the lower end of the switching bracket 33 via a collar 34. The lower end of the switching bracket 33 can rotate relative to the collar 34 around the central axis of the collar 34.
　ペダルアーム１１におけるペダル固定軸１４と第４ピン３５との間の部分には、カラー３４を通すための孔３７が形成されている。孔３７は、カラー３４よりも大径となっている。これにより、カラー３４は、ペダルアーム１１に対し、マスタシリンダ３１の伸縮方向についての定められた範囲での相対移動が可能とされている。 A hole 37 for passing the collar 34 is formed in a portion of the pedal arm 11 between the pedal fixing shaft 14 and the fourth pin 35. The hole 37 has a larger diameter than the collar 34. This allows the collar 34 to move relative to the pedal arm 11 within a predetermined range in the direction of expansion and contraction of the master cylinder 31.
　バイワイヤ動作モードのとき、カラー３４は図３Ｂに示すように位置する。一方、バイワイヤ非動作モードのときには、マスタシリンダ３１によってブレーキ装置に対する油圧の付与が行われるようになる。マスタシリンダ３１に上記油圧が作用することに伴ってマスタシリンダ３１が伸長すると、マスタシリンダ３１に連結されたカラー３４が図４Ｂに示すようにペダルアーム１１に対し上記定められた範囲で相対移動する。このカラー３４の相対移動に伴い、カラー３４に連結された切換ブラケット３３が、ペダルアーム１１に対し第４ピン３５の中心軸線周りに図４Ａに矢印Ｙ４で示すように相対回転する。 When in the by-wire mode of operation, the collar 34 is positioned as shown in Figure 3B. On the other hand, in the by-wire non-operation mode, the master cylinder 31 applies hydraulic pressure to the brake device. When the master cylinder 31 expands as the hydraulic pressure acts on the master cylinder 31, the collar 34 connected to the master cylinder 31 moves relative to the pedal arm 11 within the predetermined range as shown in FIG. 4B. . With this relative movement of the collar 34, the switching bracket 33 connected to the collar 34 rotates relative to the pedal arm 11 around the central axis of the fourth pin 35 as shown by arrow Y4 in FIG. 4A.
　この切換ブラケット３３の相対回転は、反力装置である上記伸縮装置１２の反力に抗して行われる。すなわち、マスタシリンダ３１が上記油圧によって伸長するときに発生する力よりも、伸縮装置１２の反力が小さくなるように設定されている。言い換えれば、切換ブラケット３３に作用する伸縮装置１２の反力とマスタシリンダ３１の上記油圧に基づく力との関係は、伸縮装置１２の反力よりもマスタシリンダ３１の上記油圧に基づく力の方が大きくなるよう設定されている。これにより、カラー３４の上記相対移動、すなわち切換ブラケット３３の上記相対回転が可能になる。切換ブラケット３３の上記相対回転により、第１ピン１８が切換ブラケット３３の上端部によって図４Ａの左方に押される。その結果、第１ピン１８は、図６に二点鎖線で示す連結位置Ｐ１から実線で示す非連結位置Ｐ２まで移動する。 This relative rotation of the switching bracket 33 is performed against the reaction force of the telescopic device 12, which is a reaction force device. That is, the reaction force of the expansion/contraction device 12 is set to be smaller than the force generated when the master cylinder 31 is expanded by the above-mentioned hydraulic pressure. In other words, the relationship between the reaction force of the telescoping device 12 acting on the switching bracket 33 and the force based on the hydraulic pressure of the master cylinder 31 is such that the force based on the hydraulic pressure of the master cylinder 31 is stronger than the reaction force of the telescoping device 12. It is set to be large. This allows the relative movement of the collar 34, that is, the relative rotation of the switching bracket 33. Due to the relative rotation of the switching bracket 33, the first pin 18 is pushed to the left in FIG. 4A by the upper end of the switching bracket 33. As a result, the first pin 18 moves from the connected position P1 shown by the two-dot chain line in FIG. 6 to the unconnected position P2 shown by the solid line.
　第１ピン１８が非連結位置Ｐ２に移動すると、ペダルアーム１１の凹部３６から第１ピン１８が抜き出されるため、ペダルアーム１１に対する第１ピン１８の連結が解除される。このため、反力装置である上記伸縮装置１２（図４Ａ）から、リンク機構１３の第１ピン１８を介してのペダルアーム１１への反力の伝達が遮断される。その結果、ペダルアーム１１が踏み込まれる際に伸縮装置１２からペダルアーム１１に反力が伝達されなくなる。 When the first pin 18 moves to the uncoupled position P2, the first pin 18 is pulled out from the recess 36 of the pedal arm 11, so that the first pin 18 is disconnected from the pedal arm 11. Therefore, transmission of reaction force from the telescopic device 12 (FIG. 4A), which is a reaction force device, to the pedal arm 11 via the first pin 18 of the link mechanism 13 is blocked. As a result, when the pedal arm 11 is depressed, no reaction force is transmitted from the expansion/contraction device 12 to the pedal arm 11.
　次に、本実施形態における車両のペダル装置の作用効果について説明する。
　（２－１）第１実施形態と同様に、リンク機構１３が車両の前後方向に大型化することを抑制できる。 Next, the effects of the vehicle pedal device in this embodiment will be explained.
(2-1) Similar to the first embodiment, it is possible to suppress the link mechanism 13 from increasing in size in the longitudinal direction of the vehicle.
　（２－２）バイワイヤ動作モードのとき、反力装置である伸縮装置１２の反力により、リンク機構１３の第１ピン１８が連結位置Ｐ１に保持される。このとき、運転者によってペダルアーム１１が踏み込まれると、リンク機構１３を介して伸縮装置１２が収縮する。そのことに伴って伸縮装置１２からの反力が連結リンク１６及び第１ピン１８を介してペダルアーム１１に作用する。このときにはペダルアーム１１の踏み込みに伴ってマスタシリンダ３１が収縮しても、その収縮に伴うブレーキ装置に対する油圧の付与が行われないため、ペダルアーム１１にマスタシリンダ３１からの反力が伝達されることはない。 (2-2) In the by-wire operation mode, the first pin 18 of the link mechanism 13 is held at the connection position P1 by the reaction force of the expansion and contraction device 12, which is a reaction force device. At this time, when the pedal arm 11 is depressed by the driver, the telescoping device 12 contracts via the link mechanism 13. Accordingly, a reaction force from the expansion/contraction device 12 acts on the pedal arm 11 via the connecting link 16 and the first pin 18. At this time, even if the master cylinder 31 contracts as the pedal arm 11 is depressed, no hydraulic pressure is applied to the brake device due to the contraction, so the reaction force from the master cylinder 31 is transmitted to the pedal arm 11. Never.
　バイワイヤ非動作モードのときには、マスタシリンダ３１によってブレーキ装置に対する油圧の付与が行われるようになる。そして、マスタシリンダ３１に上記油圧が作用することに伴ってマスタシリンダ３１が伸長すると、マスタシリンダ３１に連結されたカラー３４がペダルアーム１１に対し上記定められた範囲で相対移動する。このカラー３４の相対移動に伴い、カラー３４に連結された切換ブラケット３３がペダルアーム１１に対し第４ピン３５の中心軸線周りに相対回転するため、連結位置Ｐ１に保持された第１ピン１８が非連結位置Ｐ２に移動する。これにより、ペダルアーム１１に対する第１ピン１８の連結が解除されるため、伸縮装置１２から連結リンク１６及び第１ピン１８を介してのペダルアーム１１への反力の伝達が遮断される。その結果、ペダルアーム１１が踏み込まれる際に伸縮装置１２からペダルアーム１１に反力が伝達されなくなる。 In the by-wire non-operation mode, the master cylinder 31 applies hydraulic pressure to the brake device. When the master cylinder 31 expands as the hydraulic pressure acts on the master cylinder 31, the collar 34 connected to the master cylinder 31 moves relative to the pedal arm 11 within the predetermined range. With this relative movement of the collar 34, the switching bracket 33 connected to the collar 34 rotates relative to the pedal arm 11 around the central axis of the fourth pin 35, so that the first pin 18 held at the connecting position P1 Move to uncoupled position P2. As a result, the connection of the first pin 18 to the pedal arm 11 is released, so that the transmission of reaction force from the expansion/contraction device 12 to the pedal arm 11 via the connection link 16 and the first pin 18 is interrupted. As a result, when the pedal arm 11 is depressed, no reaction force is transmitted from the expansion/contraction device 12 to the pedal arm 11.
　バイワイヤ非動作モードのときには、ペダルアーム１１が踏み込まれることに伴ってマスタシリンダ３１が収縮すると、その収縮に基づきブレーキ装置に対する油圧の付与が行われるため、ペダルアーム１１にはマスタシリンダ３１からの反力が作用する。このときには伸縮装置１２からペダルアーム１１への反力の伝達が上述したように遮断されるため、ペダルアーム１１が踏み込まれる際に伸縮装置１２からペダルアーム１１に反力が伝達されることはない。従って、マスタシリンダ３１からの反力に加えて伸縮装置１２からの反力がペダルアーム１１に伝達されることがないので、ペダルアーム１１に作用する反力が大きくなることを回避できる。 In the by-wire non-operation mode, when the master cylinder 31 contracts as the pedal arm 11 is depressed, hydraulic pressure is applied to the brake device based on the contraction, so the pedal arm 11 receives no reaction from the master cylinder 31. Force acts. At this time, the transmission of the reaction force from the telescoping device 12 to the pedal arm 11 is interrupted as described above, so no reaction force is transmitted from the telescoping device 12 to the pedal arm 11 when the pedal arm 11 is depressed. . Therefore, since the reaction force from the expansion and contraction device 12 in addition to the reaction force from the master cylinder 31 is not transmitted to the pedal arm 11, it is possible to avoid an increase in the reaction force acting on the pedal arm 11.
　また、バイワイヤ動作モードとバイワイヤ非動作モードとで、ペダルアーム１１に作用する反力を、伸縮装置１２からの反力とマスタシリンダ３１からの反力との間で切り換えるに当たり、電磁バルブ等の高価な部品をペダル装置に設ける必要がない。このため、ペダル装置の製造コストを低く抑えることができる。 In addition, when switching the reaction force acting on the pedal arm 11 between the reaction force from the expansion and contraction device 12 and the reaction force from the master cylinder 31 between the by-wire operation mode and the by-wire non-operation mode, expensive electromagnetic valves and the like are required. There is no need to provide additional parts to the pedal device. Therefore, the manufacturing cost of the pedal device can be kept low.
