Description

【０００１】
【発明の属する技術分野】
この発明は、例えば自動車等の複数のモードを有する４輪駆動車で、各モードのポジションの切換を行う４輪駆動・２輪駆動切換スイッチを備えた４輪駆動・２輪駆動切換ギヤシフトレバーに関するものである。
【０００２】
【従来の技術】
従来、主として坂道や悪路等の走行時に利用して能力を発揮する自動車などの車両の複数のモードを有する４輪駆動車において、各モードのポジションの切換を行うための４輪駆動・２輪駆動切換スイッチを備えた４輪駆動・２輪駆動切換ギヤシフトレバーとしては、例えば実公平３−１８２６７号公報及び実開昭６１−８３２２号公報に開示された技術のものが提案されている。
【０００３】
そして、上記４輪駆動・２輪駆動切換スイッチは、通常は自動車の運転者が操作するコントロールノブの把持部の上端に配設した押釦スイッチの構成から成り、この押釦スイッチは、前者では、主変速用のシフトレバーとは独立して副変速用の高低速切換レバーの先端のギヤシフトノブに配設されており、後者では、自動車の運転者が直接に作動するマニュアルトランスミッションをリモートコントロールするシフトレバーのノブの上面に配設されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した従来の４輪駆動・２輪駆動切換スイッチは、４輪駆動と２輪駆動の２つのモードに対する２つのポジションの切換を行う押釦スイッチの構成から成っている。ところで、自動車等に実用されている４輪駆動車には、一般の道路面を走行する時の２輪駆動（２Ｈ）と雨天時やアイスバーン等の突然に状態が変化する路面を走行する時の４輪駆動（４Ｈ）の２つのモード以外に、砂地や深い雪道などの条件の悪い状態の路面を走行する時の４輪駆動（４ＨＬｃ）、岩場や泥沼地などの極悪状態の路面を走行する時の４輪駆動（４ＬＬｃ）の２つのモード、合計して２Ｈ、４Ｈ、４ＨＬｃ，４ＬＬｃの４つのモードを備えた４輪駆動車が現実に存在している。
【０００５】
従って、上記したような２Ｈ、４Ｈ、４ＨＬｃ，４ＬＬｃの４つのモードを備えた４輪駆動車では、上記した従来の４輪駆動と２輪駆動の２つのモードのポジションの切換を行う押釦スイッチを使用した場合に、４つのモードを備えた４輪駆動車用の切換スイッチとしては全く使用することができないという問題点があった。
【０００６】
この発明は、上記のような問題点を解消するためになされたもので、複数の各モードのポジションに対し揺動自在に軸支した４輪駆動・２輪駆動切換ギヤシフトレバーの下方部に操作杆を突設し、この操作杆と係合して連動する可動盤により各モードのポジションに対応する各可動接点と各固定接点とを摺動接離させる４輪駆動・２輪駆動切換スイッチを配設した構成を有し、特に、４輪駆動と２輪駆動の２つのモード以上の複数のモードを有する４輪駆動車に適合した４輪駆動・２輪駆動切換スイッチを備えた４輪駆動・２輪駆動切換ギヤシフトレバーを提供することを目的とする。

【００１７】
【発明の実施の形態】
この発明に係る４輪駆動・２輪駆動切換ギヤシフトレバーは、複数の各モードのポジションに対し揺動自在に軸支した４輪駆動・２輪駆動切換ギヤシフトレバーの下方部に操作杆を突設し、この操作杆と係合して連動する可動盤により各モードのポジションに対応する各可動接点と各固定接点とを摺動接離させる４輪駆動・２輪駆動切換スイッチを配設した構成を備えたものである。
【００１８】
従って、上記のような構成を備えた４輪駆動・２輪駆動切換ギヤシフトレバーを複数のモードを有する４輪駆動車に適用して実施した場合に、通常の４輪駆動（４Ｈ）と２輪駆動（２Ｈ）の２つのモードのポジションに対する駆動切換操作は勿論のこと、２つのモード以上のポジションに対する駆動切換操作、例えば非常に条件の悪い状態の路面を走行する時の４輪駆動（４ＨＬｃ、又は４ＬＬｃ））においても、単に１つの４輪駆動・２輪駆動切換ギヤシフトレバーを使用し、複数の各モードのポジションに対応して前後方向へ揺動操作したり、時には横方向へ回動操作又は下方向へ押圧操作したり、あるいは付属の操作釦を操作することにより、２Ｈ、４Ｈ、４ＨＬｃ、４ＨＬＬｃの４つの各モードのポジションに対応する駆動切換操作を極めて簡単に、かつ正確に行うことができるものである。
【００１９】
それゆえ、この発明による４輪駆動・２輪駆動切換ギヤシフトレバーは、この４輪駆動・２輪駆動切換ギヤシフトレバーを支持するケース体の内部空間を利用して各モードのポジションに対応する節度機構、スイッチユニット等の各部品を配設したので、装置自体を小型化できると共に、４輪駆動車の室内空間への影響を小さくでき、さらに、ケース体の下方部にスイッチユニットを設けたことにより、容易にストロークを確保できるために駆動切換操作を確実に実現できるなどの優れた効果を発揮するものである。
【００２０】
【実施例】
実施例１．
以下、この発明の実施例について説明する。図１は、この発明の第１の実施例である４輪駆動・２輪駆動切換ギヤシフトレバーの構成を概略的に示す断面図、図２は、図１をＡ−Ａ線で切断して示す断面図、図３は、図１の構成を概略的に示す分解斜視図である。図１、図２及び図３において、１は４輪駆動・２輪駆動切換ギヤシフトレバー（略呼称名はギヤシフトレバー）であり、このギヤシフトレバー１は複数の各モードのポジションに対して揺動自在に、ケース体７内の軸支部２により軸支される。また、ギヤシフトレバー１はケース体７に対して揺動自在に、ケース体７内の軸支部２とは直交するピン軸部２ａにより軸支される。
【００２１】
また、ギヤシフトレバー１は、その上方部にノブ１ａを装着しており、軸支部２の下方部に４輪駆動・２輪駆動切換スイッチ（略呼称名は切換スイッチ）３の可動盤４の係合部４ａに係合する操作杆５を突設している。切換スイッチ３は、操作杆５と連動して左右方向へ、かつ水平方向へ移動する各モードのポジションに対応する各可動接点６ａを設けた可動盤４と、この可動盤４の各可動接点６ａと摺動接離する各モードのポジションに対応する各固定接点６ｂを設けた基板１２とから構成される。
【００２２】
さらに、ギヤシフトレバー１は、その下端部に形成した嵌入穴１ｂ内へ挿入した節度ばね９により弾性付勢された球状体から成る節度体８を配設しており、この節度体８はギヤシフトレバー１の下端面より突出して配置される。節度体８は、ケース体７の下面の開口部に嵌着される極盤１０の盤面に形成した波形状の節度溝１１に対し、節度ばね９の弾性力により圧接した状態で配設されており、これにより、ギヤシフトレバー１を各モードの所定のポジションに確実に設定して保持することができる。
【００２３】
極盤１０は、節度溝１１を形成した盤面に隣接して可動盤４と基板１２とから成る切換スイッチ３を内部に配設する収納部１３を形成しており、この収納部１３は、その下面を極盤１０を覆う蓋部材１４で閉塞されている。収納部１３は、図１及び図２に示されるようにケース体７の下方部に配設されており、また、収納部１３は、操作杆５に係合する可動盤４の係合部４ａを左右方向へ、かつ水平方向へ移動自在に案内する第１案内溝１０ａと、可動盤４の側面に形成したガイド凸部４ｂが係合する第２案内溝１０ｂとを形成している。
【００２４】
また、極盤１０は、ギヤシフトレバー１を各モードのポジションに保持するために極盤１０の盤面に形成した節度溝１１の一部に、ギヤシフトレバー１の移動方向を規制する規制突起１５を形成している。
【００２５】
上記した構成を有するこの発明の第１の実施例である４論駆動・２輪駆動切換ギヤシフトレバーにおいて、運転者が図２に示すノブ１ａを把持してギヤシフトレバー１を軸支部２を軸として前後方向へ揺動操作し、図１に示す各モードのポジションである２輪駆動（２Ｈ）、自動選択駆動（ＡＵＴＯ）及び４輪駆動（４Ｈ）の各設定位置を選択すると、ギヤシフトレバー１の下端部に配設している節度ばね９で弾性付勢された節度体８は、極盤１０の盤面に形成した波形状の節度溝１１に圧接した状態で位置するため、ギヤシフトレバー１は各モードの所定のポジションに確実に設定され、かつ保持される。
【００２６】
次に、通常の４輪駆動（４Ｈ）以外の４輪駆動（４ＨＬｃ又は４ＬＬｃ）の各ポジションを選択する時には、ギヤシフトレバー１の揺動操作に応じて移動する節度体８は、節度溝１１の一部に形成した図３に示す規制突起１５に当接するために、ギヤシフトレバー１の移動は阻止された状態にある。そこで、図２に示すギヤシフトレバー１を軸支部２と直交するピン軸部２ａを軸として横方向へわずかに回動操作すると、ギヤシフトレバー１に対する移動の阻止状態が解除される。次いで、再びギヤシフトレバー１を上記と同方向へ揺動操作することにより、４輪駆動（４ＨＬｃ又は４ＬＬｃ）の各設定位置を容易に選択することができるようになる。
【００２７】
上記したようにギヤシフトレバー１を各モードのポジションに対応して揺動操作する時、ギヤシフトレバー１の下方部に突設した操作杆５と係合する係合部４ａを介して切換スイッチ３の可動盤４は、第１案内溝１０ａ及び第２案内溝１０ｂに案内されて左右方向へ、かつ水平方向へ移動する。可動盤４の移動に応じて、この可動盤４に設けた各モードのポジションに対応する各可動接点６ａは、基板１２に設けた各モードのポジションに対応する各固定接点６ｂと摺動接離し、そのため、電子制御回路（図示しない）による各モードのポジションに対する駆動切換操作が行われることになる。
【００２８】
実施例２．
図４は、この発明の第２の実施例である４輪駆動・２輪駆動切換ギヤシフトレバーの構成を概略的に示す断面図、図５は、図４をＢ−Ｂ線で切断して示す断面図、図６は、図５の一部をＣ−Ｃ線で切断して示す拡大断面図、図７は、図４の構成を概略的に示す分解斜視図である。図４、図５、図６及び図７において、１８はギヤシフトレバーであり、このギヤシフトレバー１８は下端部をスプリング１６を介して支持部材１７に配設している。また、ギヤシフトレバー１８は複数の各モードのポジションに揺動自在に軸支部１９により軸支される。
【００２９】
また、ギヤシフトレバー１８は、その上方部にノブ１８ａを装着しており、軸支部１９の下方部に切換スイッチ２０の可動盤２１の係合部２１ａに係合する操作杆２２を突出している。切換スイッチ２０は、上記第１の実施例である図２に示す切換スイッチ３と同一な構成を備えているものであるから、その説明は省略する。
【００３０】
支持部材１７にピンガイド２５を上下動自在に配設しており、このピンガイド２５は第１ピン２３と第２ピン２４を備えている。第１ピン２３はギヤシフトレバー１８とピンガイド２５に固着すると共に、第１ピン２３の先端部は支持部材１７に形成した案内溝１７ａに上下動自在に配設している。第２ピン２４はピンガイド２５に固着しており、この第２ピン２４はガイドプレート２７に形成したガイド溝２６に係合している。
【００３１】
ガイド溝２６は、図４及び図７に示すようにギヤシフトレバー１８を各モードのポジションに揺動操作させることを可能にする横溝２６ａを備えており、また、ギヤシフトレバー１８をスプリング１６の弾性力に抗して下方向へ押圧した時にのみ、ギヤシフトレバー１８を上下移動させることを可能にする縦溝２６ｂを備えている。ギヤシフトレバー１８を各モードのポジションに揺動操作した時、ギヤシフトレバー１８を各モードの所定のポジションに設定し、かつ保持する節度機構については、上記第１の実施例である図１及び図２に示す節度機構の構成とほぼ同一であるので、その説明は省略する。
【００３２】
上記した構成を有するこの発明の第２の実施例である４輪駆動・２輪駆動切換ギヤシフトレバーにおいて、運転者が図５に示すノブ１８ａを把持してギヤシフトレバー１８を軸支部１９を軸として前後方向へ揺動操作し、図４に示す各モードのポジションである２輪駆動（２Ｈ）、自動選択駆動（ＡＵＴＯ）及び４輪駆動（４Ｈ）の各設定位置を選択すると、ギヤシフトレバー１８は、上記第１の実施例の図１及び図２に示すものと同一の構成の節度機構によって各モードの所定のポジションに確実に設定され、かつ保持される。この時、ピンガイド２５に固着した第２ピン２４は、ガイドプレート２７に形成したガイド溝２６の横溝２６ａと係合して移動し、ギヤシフトレバー１８の揺動操作を可能とさせる。
【００３３】
次に、通常の４輪駆動（４Ｈ）以外の４輪駆動（４ＨＬｃ又は４ＬＬｃ）の各ポジションを選択する時には、ガイド溝２６の横溝２６ａと係合している第２ピン２４は、横溝２６ａの一部に形成した縦溝２６ｂの存在によって移動が阻止され、その結果、ギヤシフトレバー１８もその揺動操作が阻止された状態にある。そこで、図４及び図５に示すようにノブ１８ａを介してギヤシフトレバー１８をスプリング１６の弾性力に抗して下方向へ押圧すると、ギヤシフトレバー１８に固着した第１ピン２３は案内溝１７ａに案内されて下方向へ移動し、これと同時にピンガイド２５に固着した第２ピン２４は、係合しているガイド溝２６の横溝２６ａと連通する縦溝２６ｂと係合して下方向へ移動する。
【００３４】
その後、ギヤシフトレバー１８に付加した押圧力を解除すると、ギヤシフトレバー１８はスプリング１６の弾性力によって元の位置に復帰し、そのため、第２ピン２４はガイド溝２６の横溝２６ａと係合することにより、ギヤシフトレバー１８の揺動操作を可能とさせる状態となる。それゆえ、ギヤシフトレバー１８を４輪駆動（４ＨＬｃ又は４ＬＬｃ）の各ポジションの設定位置に選択的に設定することができるようになる。
【００３５】
上記したギヤシフトレバー１８を各モードのポジションに対応して揺動操作する時、ギヤシフトレバー１８の支持部材１７に突設した操作杆２２と係合する係合部２１ａを介して切換スイッチ２０の可動盤２１は、左右方向へ、かつ水平方向に移動するので、切換スイッチ２０は上記第１の実施例である図２に示す切換スイッチ３と同様に作動する。
【００３６】
実施例３．
図８は、この発明の第３の実施例である４輪駆動・２輪駆動切換ギヤシフトレバーの構成を概略的に示す断面図、図９は、図８をＤ−Ｄ線で切断して示す断面図である。この発明の第３の実施例のものは、ギヤシフトレバーの構成の一部について、上記第２の実施例のものと相違している。図８及び図９において、３１はギヤシフトレバーであり、このギヤシフトレバー３１の上方部に横方向に突出した把持部２８を有するノブ２９を装着している。このノブ２９の把持部２８に形成した嵌合穴２８ａ内に、操作釦３０を移動自在に配設している。３３は下端部にピン３２を配設したロッドであり、このロッド３３はギヤシフトレバー３１に上下動自在に内設している。
【００３７】
ロッド３３の上端部は、ノブ２９に揺動自在に軸支した揺動杆２８ｂの一端部を回動自在に連結しており、揺動杆２８ｂの他端部は操作釦３０に回動自在に連結している。また、操作釦３０は、その一端の操作面３０ａをノブ２９の把持部２８の下面に突出して配置している。ロッド３３の下端部に配設したピン３２は、ガイドプレート３５に形成したガイド溝３４に係合している。
【００３８】
ガイドプレート３５のガイド溝３４は、図８に示すようにギヤシフトレバー３１を各モードのポジションに揺動操作させることを可能にする横溝３４ａを備えており、また、ギヤシフトレバー３１を弾性力に抗して下方向へ押圧した時にのみ、ギヤシフトレバー３１を上下移動させることを可能にする縦溝３４ｂを備えている。
【００３９】
上記した構成を有するこの発明の第３の実施例である４輪駆動・２輪駆動切換ギヤシフトレバーにおいて、上記第２の実施例のものが４輪駆動（４ＨＬｃ又は４ＬＬｃ）の各ポジションを選択する時に、ギヤシフトレバー１８自体を弾性力に抗して下方向へ押圧して駆動切換操作を行っているのに対し、この発明の第３の実施例のものでは、ギヤシフトレバー３１に上下動自在に内設しているロッド３３を操作釦３０を介し、弾性力に抗して下方向へ押圧して駆動切換操作を行っている点で相違している。
【００４０】
よって、上記相違点について説明する。運転者が図９に示すノブ２９の把持部２８を把持し、この把持部２８の下面に突出している操作釦３０の操作面３０ａに対し押圧力を付加して操作釦３０を嵌合穴２８ａ内に押し込むと、操作釦３０に回動自在に連結している揺動杆２８ｂを介して、この揺動杆２８ｂの一端部と回動自在に連結しているロッド３３の上端部は、操作釦３０に対する上記押圧力に連動し、かつ弾性力に抗して下方向へ押圧作動される。
【００４１】
ロッド３３の下方向への移動に伴って、ロッド３３の下端部に配設したピン３２は、図８に示すガイドプレート３５に形成したガイド溝３４の横溝３４ａと係合している状態から、この横溝３４ａと連通する縦溝３４ｂと係合して下方向へ移動する。このような動作態様は、上記第２の実施例のものにおける図４に示すように、ガイドプレート２７に形成されたガイド溝２６の横溝２６ａ及び縦溝２６ｂと、この各横溝２６ａ及び縦溝２６ｂに係合して移動する第２ピン２４との関連動作と同様である。
【００４２】
【発明の効果】
以上のように、この発明によれば、ノブを装着しノブの操作に応じて複数の各モードのポジションの切換を行う４輪駆動・２輪駆動切換スイッチを備えた４輪駆動・２輪駆動切換ギヤシフトレバーにおいて、上記４輪駆動・２輪駆動切換ギヤシフトレバーは、各モードのポジションに揺動自在に軸支部で軸支すると共に、この軸支部よりノブの装着方向とは反対方向の下方の位置に上記４輪駆動・２輪駆動切換スイッチの可動盤に係合する操作杆を突設して成る構成とし、下端部に、節度ばねにより弾性付勢された節度体を配設して成る構成とし、上記節度体は、上記ケース体の下方側の開口部に嵌着され上記４輪駆動・２輪駆動切換スイッチを配設した極盤の盤面に形成した波形状の節度溝に上記節度ばねの弾性力により圧接して成る構成とし、上記４輪駆動・２輪駆動切換スイッチは、上記操作杆と連動して移動する各モードのポジションに対応する各可動接点を設けた上記可動盤と、この可動盤の各可動接点が摺動接離する各モードのポジションに対応する各固定接点を設けた基板とから成る構成とし、上記極盤は、上記節度溝を形成した盤面に隣接して上記可動盤と上記基板とを内部に配設する収納部を形成して成る構成を備えたので、このような構成を備えた４輪駆動・２輪駆動切換ギヤシフトレバーを複数のモードを有する４輪駆動車に実施した場合に、通常の４輪駆動（４Ｈ）と２輪駆動（２Ｈ）の２つのモードのポジションに対する駆動切換操作は勿論のこと、２つのモード以上のポジションに対する駆動切換操作、例えば４輪駆動（４ＨＬｃ又は４ＬＬｃ）においても、単に１つの４輪駆動・２輪駆動切換ギヤシフトレバーを使用するのみで、２Ｈ、４Ｈ、４ＨＬｃ、４ＬＬｃの４つに各モードのポジションに対応する駆動切換操作を極めて簡単、かつ正確に行うことができるものである。
【００４３】
また、この発明に係わる４輪駆動・２輪駆動切換ギヤシフトレバーを支持するケース体の内部空間を利用して各モードのポジションに対する節度機構、スイッチユニット等の各部品を配設したので、装置自体を小型化できると共に、４輪駆動車の室内空間への影響を小さくでき、さらに、ケース体の下方部にスイッチユニットを設けたことにより、容易にストロークを確保できるために駆動切換操作を確実に実現できるなど優れた効果を奏する。
