Description

【０００１】
【発明の属する技術分野】
本発明は、衝突試験をより精度よく実施するのに好適な車両衝突試験装置に関する。
【０００２】
【従来の技術】
車両の衝突試験を実施するには、実際の車両をバリア（固定壁）に衝突させる実車試験が一般的に行われる。
このような試験を行う車両衝突試験装置としては、例えば、特開平８−１４５８３９号公報「車両衝突試験装置における連結ワイヤーの外れ止め装置」が知られている。
【０００３】
同公報の図１及び図２には、衝突バリア１１（符号は公報に記載されているものを使用した。以下同様。）の手前の走行路に溝部１を設け、この溝部１にガイドレール２を敷設し、このガイドレール２にテスト車両Ｖを衝突バリア１１へ誘導するためのスケーターＳを移動可能に取付けるとともに、ガイドレール２に、牽引用ワイヤロープＷａに取付けるとともにスケーターＳに連結したスケーター２６を移動可能に取付け、ガイドレール２の衝突バリア１１側の端部に、スケーターＳ，２６を衝突させるためのストライカー３５を取付けた車両衝突試験装置が記載されている。
【０００４】
【発明が解決しようとする課題】
上記技術では、スケーターＳ、スケーター２６及びストライカー３５は、どれも床面より上方に突出している。
例えば、衝突バリア１１をテスト車両Ｖの進行方向に対して左右にオフセットさせて衝突させるオフセット衝突試験では、基準のオフセット量に対するテスト車両Ｖのオフセット誤差を小さくするために衝突バリア１１にテスト車両ＶをスケーターＳでできるだけ近づけて衝突させる必要があり、衝突直後にテスト車両Ｖが上記したスケーターＳ、スケーター２６又はストライカー３５に当たったり、テスト車両Ｖの走行路の溝部１の幅が大きいために、衝突後にテスト車両Ｖの車輪が溝部１に嵌まって、衝突試験が精度よく実施されず、再試験などの手間を要していた。
【０００５】
そこで、本発明の目的は、車両衝突試験装置を改良することで、衝突試験をより精度よく実施することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために請求項１は、試験車をけん引手段を用いてバリアの近傍までけん引し、バリアから所定距離手前の位置で前記試験車をけん引手段から切り離し、このけん引手段を制動手段で停止させるようにした車両衝突試験装置において、けん引手段と、このけん引手段をバリアに導くガイドレールと、制動手段とを、試験車が走行する走行路面よりも下方に配置し、試験車をけん引するためにけん引手段に取付けた試験車連結用フックの幅をガイドレールの幅よりも小さくするとともに試験車連結用フックを走行路面より上方に突出させ、試験車連結用フックをけん引手段にスイング可能に取付け、けん引手段がバリアから所定距離手前の位置に達したときに試験車連結用フックを走行路面より下方に倒すフック傾倒手段を制動手段に設けたことを特徴とする。
【０００７】
けん引手段、ガイドレール及び制動手段を走行路面よりも下方に配置し、試験車連結用フックを走行路面より上方に突出させたことで、走行路面上には必要最小限の試験車連結用フックしか突出せず、試験車の走行を阻害することがない。従って、試験車の衝突試験をより精度よく実施することができる。
【０００８】
また、フック傾倒手段を制動手段に設けたことで、けん引手段がバリアから所定距離手前の位置に達したときは、フック傾倒手段で試験車連結用フックを走行路面より下方に倒すことができ、試験車がバリアに衝突するとき及び衝突した後に走行路面から突出するものが全くなくなるため、試験車の走行を阻害することがなく、試験車の衝突試験をより一層精度よく実施することができる。
【０００９】
請求項２は、けん引手段を、ガイドレールに走行自在に取付けた主けん引部と、この主けん引部に取付けた試験車連結用フックと、主けん引部の走行方向に一定距離移動可能に取付けたスライド部材と、このスライド部を高位置に保持すべく主けん引部に内蔵したスライド部材保持部とから構成し、このスライド部材保持部に載った状態のスライド部材と試験車連結用フックとで、バリア側に送るようにしたけん引ワイヤを挟み、制動手段を、前進中のスライド部材を止めてスライド部材保持部から脱落させるためのストッパと、このストッパ作動後に試験車連結用フックを走行路面下方へ倒すフック傾倒手段とから構成した。
【００１０】
主けん引部、スライド部材、けん引ワイヤ、ストッパ、フック傾倒手段は走行路面下に配置し、試験車連結用フックは走行路面上から走行路面下へ傾けるようにしたことで、試験車がバリアに衝突する前から衝突した後にかけて試験車連結用フックに当たるのを防止することができる。従って、試験車の衝突試験をより精度よく実施することができる。
【００１１】
また、試験車を走行させる走行路にフックを移動させるために設ける隙間を小さくすることができ、衝突した試験車の車輪が隙間に嵌まることを防止することができ、より一層精度よく衝突試験の実施が可能になる。
【００１２】
請求項３は、走行路面に、けん引手段、ガイドレール及び制動手段を収納する凹部を形成し、この凹部の上部開口部のうち、少なくとも試験車連結用フックが移動する部分を除いて着脱可能なカバーで塞いだことを特徴とする。
【００１３】
カバーを外すことにより、凹部内のけん引手段、ガイドレール及び制動手段のメンテナンスを容易に行うことができる。
【００１４】
請求項４は、試験車をけん引手段を用いてバリアの近傍までけん引し、バリアから所定距離手前の位置で前記試験車をけん引手段から切り離し、このけん引手段を制動手段で停止させるようにした車両衝突試験装置において、けん引手段と、このけん引手段をバリアに導くガイドレールと、制動手段とを、試験車が走行する走行路面よりも下方に配置し、試験車連結用フックをけん引手段にスイング可能に取付け、けん引手段がバリアから所定距離手前の位置に達したときに試験車連結用フックを走行路面より下方に倒すフック傾倒手段を制動手段に設けたことを特徴とする。
【００１５】
けん引手段、ガイドレール及び制動手段を走行路面よりも下方に配置したことで、試験車の走行を阻害することがない。従って、試験車の衝突試験をより精度よく実施することができる。
【００１６】
また、フック傾倒手段を制動手段に設けたことで、けん引手段がバリアから所定距離手前の位置に達したときは、フック傾倒手段で試験車連結用フックを走行路面より下方に倒すことができ、試験車がバリアに衝突するとき及び衝突した後に走行路面から突出するものが全くなくなるため、試験車の走行を阻害することがなく、試験車の衝突試験をより一層精度よく実施することができる。
【００１７】

スライド部材３２は、板状の部材の上面に中間部材３４に当てたローラ４３，４３を取付け、下面にスライド部材保持部３３，３３に当てたローラ４４，４４を設けたものである。なお、３４ａ，３４ｂはローラ４３，４３に当てるために中間部材３４に設けたローラ当て部である。
【００２１】

【００２６】
以上に述べた車両衝突試験装置の作用を次に説明する。
図７（ａ）〜（ｄ）は本発明に係る車両衝突試験装置の作用を説明する第１作用図であり、車両が停止した状態から衝突するまでの過程を順に説明する。
（ａ）は車両が停止した状態を示す。車両１１は、けん引装置１６及び引張装置１７に連結されていない。
【００２７】
（ｂ）はケーブル２１のバリア１３側への送りを開始し、けん引装置１６で車両１１をけん引するとともに引張装置１７で車両１１に後方への引張力を作用させた状態を示す。
【００２８】
（ｃ）は車両１１がバリア１３へ衝突する直前に、バリア１３から所定距離手前の位置でけん引装置１６を制動装置１８に当て始め、けん引装置１６の制動を開始するとともにけん引装置１６から車両１１を切り離す状態を示す。
【００２９】
（ｄ）は車両１１がバリア１３に衝突した際に、制動装置１８にてけん引装置１６の制動を継続するとともに、けん引装置１６に引張装置１７を当てて引張装置１７を制動する状態を示す。
【００３０】
図８（ａ），（ｂ）は本発明に係る車両衝突試験装置の作用を説明する第２作用図であり、（ａ）は図７（ａ）に示したけん引装置１６及び引張装置１７の拡大図、（ｂ）は図７（ｂ）に示したけん引装置１６及び引張装置１７の拡大図である。
（ａ）において、けん引装置１６のフック３１は前部連結ワイヤ２２から外れた状態にあり、引張装置１７のフック６２は後部連結ワイヤ２３から外れた状態にある。
【００３１】
（ｂ）において、ケーブル２１が前方に送られると、ケーブル２１の自重によってケーブル２１と中間部材３４，３４とに摩擦力が発生する。この時、引張装置１７側の中間部材３４をけん引装置１６側の中間部材３４よりも低くしておけば、ケーブル２１と引張装置１７側の中間部材３４との摩擦力を小さくすることができ、引張装置１７のバリア１３側への進行速度をけん引装置１６のバリア１３側への進行速度よりも遅くすることができる。
【００３２】
従って、けん引装置１６が進行することで、フック３１を前部連結ワイヤ２２に掛けることができ、この結果、けん引装置１６で車両１１（図７（ｂ）参照）を引き、更に、車両１１を引くことで、後部連結ワイヤ２３をフック６２に掛けることができ、引張装置１７によって車両１１に後方への引張力を与えることができる。
【００３３】
図９（ａ），（ｂ）は本発明に係る車両衝突試験装置の作用を説明する第３作用図であり、（ａ）は図７（ｃ）に示したけん引装置１６の拡大図、（ｂ）は図７（ｄ）に示したけん引装置１６の拡大図である。
（ａ）において、けん引装置１６のスライド部材３２の先端が、制動装置１８のマス５４に当たると、マス５４は白抜き矢印の向きにスプリング５５の弾性力に抗して移動し、制動装置１８はけん引装置１６の衝突時の衝撃を緩和する。
これとともに、スライド部材３２はスライド部材保持部３３，３３から矢印の向きに落下し始める。
【００３４】
この結果、スライド部材３２のローラ４３，４３に載っていた中間部材３４がケーブル２１とともに下降し始める。
更に、制動装置１８のストッパ用バー５７がフック３１の前部に当たるため、上記したケーブル２１の下降も手伝って、フック３１は支軸４２を中心にして矢印の向きに倒れ始める。
このようにして、前部連結ワイヤ２２からフック３１が外れ始める。
【００３５】
（ｂ）において、更に、けん引装置１６が移動すると、スライド部材３２の先端はマス５４を更に前方へ移動させるとともにスライド部材３２は落下し、これに伴って、中間部材３４及びケーブル２１は更に下降し、また、フック傾倒用バー５７はフック３１を更に押し倒すため、フック３１は車両が衝突する直前に走行路面１２ａの下に隠れ、衝突時及び衝突後もフック３１はその状態を継続する。
【００３６】
図１０は本発明に係る車両衝突試験装置の作用を説明する第４作用図であり、図７（ｄ）に示した引張装置１７の拡大図である。
車両が衝突する直前からそれ以降では、引張装置１７のスライド部材３２がけん引装置１６の後部に衝突する。これによって、スライド部材３２はスライド部材保持部６３，６３から落下するため、これに伴って中間部材３４及びケーブル２１が落下する。この結果、フック６２の下方にフック６２の回転を規制するものがなくなり、衝突時の慣性力がフック６２に作用して、フック６２は支軸６７を中心にして矢印の向きに倒れ、走行路面１２ａの下に隠れる。
【００３７】
図１１は本発明に係る車両衝突試験装置の作用を説明する第５作用図であり、車両１１がバリア１３に衝突した直後にバリア１３に跳ね返されて斜めに後退した状態を示す。この時、走行路面１２ａにはフック３１，６２が突出しないため、衝突直後に車両１１に当たることがない。また、スリット５２の幅を小さくしたため、車輪１１ｄ…がスリット５２に嵌まることがない。
【００３８】
以上の図１、図３、図４及び図５で説明したように、本発明は第１に、車両１１をけん引装置１６を用いてバリア１３の近傍までけん引し、バリア１３から所定距離手前の位置で車両１１をけん引装置１６から切り離し、このけん引装置１６を制動装置１８で停止させるようにした車両衝突試験装置１０において、けん引装置１６と、このけん引装置１６をバリア１３に導くガイドレール２６と、制動装置１８とを、車両１１が走行する走行路面１２ａよりも下方に配置し、車両１１をけん引するためにけん引装置１６に取付けたフック３１の幅ＷＨをガイドレール２６，２６の幅ＷＲよりも小さくするとともにフック３１を走行路面１２ａより上方に突出させたことを特徴とする。
【００３９】
けん引装置１６、ガイドレール２６，２６及び制動装置１８を走行路面１２ａよりも下方に配置し、フック３１を走行路面１２ａより上方に突出させたことで、走行路面１２ａ上には必要最小限のフック３１しか突出せず、車両１１の走行を阻害することがない。従って、車両１１の衝突試験をより精度よく実施することができる。
【００４０】
本発明は第２に、フック３１をけん引装置１６にスイング可能に取付け、けん引装置１６がバリア１３から所定距離手前の位置に達したときにフック３１を走行路面１２ａより下方に倒すフック傾倒用バー５７を制動装置１８に設けたことを特徴とする。
【００４１】
フック傾倒用バー５７を制動装置１８に設けたことで、けん引装置１６がバリア１３から所定距離手前の位置に達したときは、フック傾倒用バー５７でフック３１を走行路面１２ａより下方に倒すことができ、車両１１がバリア１３に衝突するとき及び衝突した後に走行路面１２ａから突出するものが全くなくなるため、車両１１の走行を阻害することがなく、車両１１の衝突試験をより一層精度よく実施することができる。
【００４２】
本発明は第３に、けん引装置１６を、ガイドレール２６に走行自在に取付けた主けん引部２８と、この主けん引部２８に取付けたフック３１と、主けん引部２８の走行方向に一定距離移動可能に取付けたスライド部材３２と、このスライド部３２を高位置に保持すべく主けん引部２８に内蔵したスライド部材保持部３３とから構成し、このスライド部材保持部３３に載った状態のスライド部材３２とフック３１とで、バリア１３側に送るようにしたケーブル２１を挟み、制動装置１８を、前進中のスライド部材３２を止めてスライド部材保持部３３から脱落させるためのマス５４と、このマス５４の作動後にフック３１を床面１４下方へ倒すフック傾倒用バー５７とから構成した。
【００４３】
主けん引部２８、スライド部材３２、ケーブル２１、マス５４、フック傾倒用バー５７は床面１４下方に配置し、フック３１は床面１４上から床面１４下方へ傾けるようにしたことで、車両１１がバリア１３に衝突する前から衝突した後にかけてフック３１に当たるのを防止することができる。従って、車両１１の衝突試験をより精度よく実施することができる。
【００４４】
また、車両１１を走行させる走行路１２の床面１４にフック３１を移動させるために設けるスリット５２を小さくすることができ、衝突前から衝突後の車両１１の車輪１１ｄ（図１１参照）がスリット５２に嵌まることを防止することができ、より一層精度よく衝突試験の実施が可能になる。
【００４５】
本発明は第４に、走行路面１２ａに、けん引装置１６、ガイドレール２６，２６及び制動装置１８を収納する凹部１５を形成し、この凹部１５の上部開口部のうち、少なくともフック３１が移動する部分を除いて着脱可能なカバー１４で塞いだことを特徴とする。
【００４６】
カバー１４を着脱可能にしたことで、カバー１４を外すことにより、凹部１５内のけん引装置１６、ガイドレール２６，２６及び制動装置１８のメンテナンスを容易に行うことができる。
【００４７】

【００５２】
請求項４の車両衝突試験装置は、けん引手段と、このけん引手段をバリアに導くガイドレールと、制動手段とを、試験車が走行する走行路面よりも下方に配置したので、試験車の走行を阻害することがない。従って、試験車の衝突試験をより精度よく実施することができる。
【００５３】
また、試験車連結用フックをけん引手段にスイング可能に取付け、けん引手段がバリアから所定距離手前の位置に達したときに試験車連結用フックを走行路面より下方に倒すフック傾倒手段を制動手段に設けたので、けん引手段がバリアから所定距離手前の位置に達したときは、フック傾倒手段で試験車連結用フックを走行路面より下方に倒すことができ、試験車がバリアに衝突するとき及び衝突した後に走行路面から突出するものが全くなくなるため、試験車の走行を阻害することがなく、試験車の衝突試験をより一層精度よく実施することができる。

BACKGROUND OF THE INVENTION
  The present invention relates to a vehicle collision test apparatus suitable for conducting a collision test with higher accuracy.
[0002]
[Prior art]
  In order to perform a vehicle collision test, an actual vehicle test in which an actual vehicle collides with a barrier (fixed wall) is generally performed.
  As a vehicle collision test apparatus for performing such a test, for example, Japanese Patent Application Laid-Open No. 8-145839 “Connecting Wire Detachment Device in a Vehicle Collision Test Apparatus” is known.
[0003]
  In FIGS. 1 and 2 of the publication, a groove portion 1 is provided in a traveling path before a collision barrier 11 (the reference numeral is the same as that described in the publication. The same applies hereinafter), and a guide rail 2 is provided in the groove portion 1. A skater S for guiding the test vehicle V to the collision barrier 11 is movably attached to the guide rail 2, and the skater 26 is attached to the guide rail 2 to the tow wire rope Wa and connected to the skater S. A vehicle collision test apparatus is described in which a striker 35 for causing the skater S, 26 to collide is attached to the end of the guide rail 2 on the side of the collision barrier 11.
[0004]
[Problems to be solved by the invention]
  In the above technique, the skater S, the skater 26, and the striker 35 all protrude upward from the floor surface.
  For example, in an offset collision test in which the collision barrier 11 is caused to collide with the traveling direction of the test vehicle V by offsetting left and right, the test vehicle V is placed on the collision barrier 11 in order to reduce the offset error of the test vehicle V with respect to the reference offset amount. Must be caused to collide with the skater S as close as possible. The test vehicle V hits the skater S, the skater 26 or the striker 35 immediately after the collision, or the width of the groove portion 1 of the travel path of the test vehicle V is large. After the collision, the wheel of the test vehicle V was fitted into the groove portion 1 and the collision test was not performed with high accuracy, requiring time and effort such as a retest.
[0005]
  Accordingly, an object of the present invention is to improve the vehicle collision test apparatus and perform the collision test with higher accuracy.
