Abstract

<P>PROBLEM TO BE SOLVED: To provide a traveling device with a simple constitution at low cost which carries out smooth turning with no skid and off-road traveling without damaging a road surface. <P>SOLUTION: The traveling device is provided with a pair of left/right driving wheels capable of carrying out separate speed control respectively; and a pair of left/right omnidirectional traveling wheels 3 arranged at a front side or a rear side of the respective driving wheels respectively and connected through a transmission mechanism so as to rotate at the same speed as the driving wheel at a rear side or a front side respectively. In the omnidirectional traveling wheel 3, a plurality of free rollers 13 are rotatably supported in a plane perpendicular to an axis of an outer peripheral part and a ground contact surface is formed by the free rollers. Thereby, if the speed of the respective driving wheels is made same, the device advances and if difference of the speed exists, the device can be turned by largely moving the omnidirectional traveling wheel connected to the faster wheel in a lateral direction without sliding by the free roller. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は走行装置に関し、詳しくは、スムーズに旋回可能なスキッドステア走行装置に関する。
【0002】
【従来の技術】
多車輪の不整地走行車やクローラ型の建設機械等に用いられているスキッドステア方式は、左右の車輪またはクローラの回転数を変えるだけで方向転換ができるため複雑な操舵装置が不必要であり、その場回転も可能というメリットがある。また、全輪を駆動することにより不整地走行能力も高いが、旋回時に路面と車輪またはクローラの間で横滑りが生じるため旋回がスムーズでなく、路面に傷をつけるというデメリットがある。
【0003】
また、前輪に自在キャスタを有する車椅子等では、スキッドステアと同様に左右の車輪回転数を変えて旋回を行い、シンプルでその場回転も可能というメリットがあり、自在キャスタを使用しているため路面を傷つけることもないが、自在キャスタは駆動できないため不整地走行能力が低いという問題点がある。
【0004】
更に、全輪を駆動する車輪型の車両の場合は、一般に旋回のために操舵輪の向きを変える方式であり旋回半径が小さくできない。また、操舵機構と駆動機構の両方を備える必要があるため機構が複雑であり、コストが高くなるという問題がある。
【0005】
この様な点を考慮してなされたもので、横滑りをおこさずに旋回可能なクローラ型の機構が知られており(例えば、特許文献1参照)、また、鼓型ローラを使用することでシンプルな構成で操舵輪の駆動を可能とした車輪型移動体が提案されている(例えば、特許文献2参照)。
【0006】

【特許文献2】
特開2001−63645号公報(第2−8頁,図1)
【0007】
【発明が解決しようとする課題】
前者はクローラ型の無限軌道にフリーローラを並べて横方向に動けるように構成したものであり、滑りを生じることなく旋回が可能であるが、この機構は横方向の規制がないため、同じものを3個以上組合わせて制御する必要があり、製造、制御方法とも複雑であり不整地移動にも向かない。また、後者は、鼓型ローラを使用することでシンプルな構成で操舵輪の駆動を可能としているが、操舵機構は別に必要であり、コストが高くなる。
【0008】
本発明は上記した点に鑑みてなされたもので、横滑りがなくスムーズな旋回が可能で路面を傷つけずに不整地走行が可能であり、かつシンプルで低コストな走行装置を提案するものである。
【0009】
【課題を解決するための手段】
本請求項1発明の走行装置は上記課題を解決するため、相対的に速度を変えられる左右少なくとも一対の駆動車輪と、各駆動車輪前方又は後方の少なくとも一方或いは両方にそれぞれ配置させるとともに、後方又は前方又は中央の駆動車輪とそれぞれ同速度の回転が可能にそれぞれ伝達機構を介して連結した左右少なくとも一対の全方向走行車輪を備え、上記全方向走行車輪は、外周部の軸心と直行する面内において回転自在に複数のフリーローラを支持させるとともに、フリーローラにより接地面を形成してなることを特徴とする走行装置として構成した。
【0010】
また、請求項2発明の走行装置は、上記左右少なくとも一対の駆動車輪が、各々個別の動力を介しての速度制御により相対的に速度を変えられる左右少なくとも一対の駆動車輪である請求項1記載の走行装置として構成した。
【0011】
また、請求項3発明の走行装置は、上記左右少なくとも一対の駆動車輪が、単一動力により駆動するとともに、車軸中央部に差動機構を設け、且つ、前後方向に対する変角方向への人力による推進力に対応させて相対的に速度を変えられる左右少なくとも一対の駆動車輪である請求項1記載の走行装置として構成した。
【0012】
また、請求項4発明の走行装置は、相対的に速度を変えられる左右一対の駆動車輪と、各駆動車輪間中央の前方又は後方の少なくとも一方或いは両方に配置させるとともに、各駆動車輪間の車軸中央部に設けた差動機構により平均化した各駆動車輪の回転速度を伝達機構を介して同速度の回動が可能に連繋した全方向走行車輪とを備え、上記全方向走行車輪は、外周部の軸心と直行する面内において回転自在に複数のフリーローラを支持させるとともに、フリーローラにより接地面を形成してなることを特徴とする走行装置として構成した。
【0013】
また、請求項5発明の走行装置は、上記左右一対の駆動車輪が、各々個別の動力を介しての速度制御により相対的に速度を変えられる左右一対の駆動車輪である請求項4記載の走行装置として構成した。
【0014】
また、請求項6発明の走行装置は、上記左右一対の駆動車輪が、単一動力により駆動するとともに、前後方向に対する変角方向への人力による推進力に対応させて相対的に速度を変えられる左右一対の駆動車輪である請求項4記載の走行装置として構成した。
【0015】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【0016】
本請求項1発明の走行装置1は、駆動車輪2と、全方向走行車輪3とを備えている。
【0017】
駆動車輪2は左右少なくとも一対設けており、相対的に速度を変えられる如く構成している。具体的には、図1の実施例の如く、各々別個の動力を介しての速度制御により相対的に速度を変えられる如く構成したもの、或いは図4に示す実施例の如く、人の力によって相対的に速度を変えられる如く構成したものが挙げられる。尚、駆動車輪2は、上記実施例の如く左右一対設けたものに限らず、左右一対の駆動車輪を前後に複数対設けた場合も本発明では該当する。その場合、同様に各々個別の複数の動力を介しての速度制御により相対的に速度を変えられる如く構成したもの、或いは、人の力によって相対的に速度を変えられる如く構成したものが挙げられる。
【0018】
全方向走行車輪3は後述する如き特殊構成をなし、また、各駆動車輪の前方又は後方にそれぞれ配置して、基本的に四輪形態の本発明走行装置を現出し、或いは各駆動車輪の前方及び後方の両方にそれぞれ配置して六輪形態の本発明走行装置を現出するものである。また、前方又は後方の駆動車輪と同速度の回転が可能に伝達機構を介して連結している。尚、駆動車輪を上記した如く複数対(例えば二対)設けた場合には、それぞれ四輪形態のものが六輪形態、六輪形態のものが八輪形態となる。
【0019】
図1は、左右一対の駆動車輪2の前方に左右一対の全方向走行車輪3を備えた例を示す。各車輪は装置本体Aより垂設した固定アーム4にそれぞれ軸着している。
【0020】
また、各駆動車輪2は各々個別の動力を介しての速度制御により相対的に速度が変えられる如く構成している。この場合の速度の制御機構は公知機構を採用でき、例えば、図示例の如く、左駆動車輪2a及び右駆動車輪2bにそれぞれ設けた各モータ5,5を速度コントローラー6介してジョイスティック7と連繋させ、ジョイスティック7の操作により左右の駆動車輪2の速度を調整できる如く構成している。尚、図示例に於いて8はバッテリーを示す。
【0021】
また、全方向走行車輪3として、各駆動車輪2の前方にそれぞれ左前部全方向走行車輪3a及び右前部全方向走行車輪3bを配置させ、伝達機構として、それぞれ後方の駆動車輪2との間にチェーン9を掛け渡している。
【0022】
各全方向走行車輪3は、上記した如く車輪本体の外周部にそれぞれ軸心と直行する面内において回転自在に複数のフリーローラを支持させるとともに、フリーローラにより接地面を形成してなるものであり、図示例の全方向走行車輪3は、図2に拡大図で示す如く二層構造をなすもので、互いに対向して対をなす複数の支持板10を周囲に突設した一対の回転板11を互いに45°回動させた状態で固定して車輪本体12を構成しており、各支持板10間に樽型のフリーローラ13をそれぞれ回動可能に軸着させている。
【0023】
尚、本発明に於ける全方向走行車輪の具体的構成はこの実施例のものに限定されず、上記要件を満たしていれば種々の形態のものが採用でき、例えば、フリーローラの数は図示例の如き数に限らず適宜選択することができ、また、その形状も樽型のものに限らない。更に、上記二層構造のものに限らず一層構造であっても三層以上の構造であっても良い。
【0024】
本発明では左右の駆動車輪の速度を変えることにより、例えば、図3に示す如く、左右の駆動車輪の軸を延長した線上の点を中心とした角速度ωの旋回動作を行う場合、全方向走行車輪の移動のベクトルは前方への駆動による走行Vと横方向へのフリーローラによる移動Sが構成されたVとなり、路面に対して滑ることなくスムーズに旋回可能である。また、全輪が駆動されているため、不整地においても一般の自在キャスターを用いた2輪駆動の車両などに比べて格段に高い走破性を有している。尚、駆動車輪が浮かないように例えばスプリングを利用したサスペンションを設けることができ、その場合さらに不整地の走破性を高めることができる。このサスペンションは後述する各実施例においても設けることができる。
【0025】
図4は左右一対の駆動車輪2の後方に左右一対の全方向走行車輪3を備えた例を示し、各駆動車輪2が人の力によって相対的に速度を変えられる如く構成した例を示すものである。
【0026】
本実施例では、全方向走行車輪3として、各駆動車輪2の後方にそれぞれ左後部全方向走行車輪3c及び右後部全方向走行車輪3dを配置させ、伝達機構として、それぞれ前方の駆動車輪2との間にチェーン9を掛け渡している。また、各駆動車輪2を単一動力により駆動するとともに、車軸中央部に差動機構を設け、更に前後方向に対する変角方向への人力による推進力に対応させて相対的に速度を変えられる如く構成している。
【0027】
具体的には、各駆動車輪2間の車軸17中央部に於いて、後述する差動機構と同様構成の差動機構15を備え、且つ、該差動機構を回動させるモータ5を備えたモータ付き差動機構を設けている。モータ5は公知手段(図示せず)により装置本体Aの把手23に備えたアクセルグリップ24に連繋している。
【0028】
この場合には人が走行装置に追いていっての操作が可能であり、通常の直進の場合にはアクセルグリップ24を操作してモータ5を回動させることにより行える。また、走行装置Aを旋回する場合には人が曲がりたい方向と逆方向に把手23に力を加えれば各全方向走行車輪3がその方向に移動するとともに、各駆動車輪2の速度が変化して所定方向への回動を行う。この際各駆動車輪2の速度の差は差動機構15により中和する。尚、本実施例以外の全ての実施例に於いて、本実施例と同様に各駆動車輪間の車軸中央部に於いて、モータ付き差動機構を採用すれば、同様に人による直進,旋回操作を行える。
【0029】
図5は左右の駆動車輪3を中央部に配置し、それぞれ前後の全方向走行車輪を駆動する6輪車の構成例を示す。左右一対の全方向走行車輪3を前後に各一対配置し、各前後の全方向走行車輪3間に各々個別の動力を介して速度制御が行える左右一対の駆動車輪2を配置しており、各駆動車輪2とその前後の全方向走行車輪3とをそれぞれリンク14を介して相互の上下動が可能に連繋させている。ここでいうリンク14は、両端を回転可能に連結した連結板状のものを示す。
【0030】
図示例を具体的に説明すると、前部には、左前部全方向走行車輪3aと右前部全方向走行車輪3bを所定間隔をあけて左右一対配置し、また、各前部全方向走行車輪後方に所定間隔をあけて左駆動車輪2a及び右駆動車輪2bをそれぞれ配置し、更に各駆動車輪後方に所定間隔をあけて左後部全方向走行車輪3c及び右後部全方向走行車輪3dをそれぞれ配置している。また、左前部全方向走行車輪3aと左駆動車輪2aとの間には、前部に左前部全方向走行車輪3aの車軸を軸着するとともに、後部に左駆動車輪2aを軸着した左前部リンク14a を設け、同様に左駆動車輪2aと左後部全方向走行車輪3cとの間に左後部リンク14b を設けている。また、右側も同様に右前部リンク14c 及び右後部リンク14d を設けている。
【0031】
また、上記前後部いずれか一方の左右対をなすリンク14の全方向走行車輪と駆動車輪の間でそれぞれ固定アーム4を介して装置本体Aを支持するとともに、他方の左右対をなすリンク14の全方向走行車輪と駆動車輪の間でそれぞれリンク14e を介して装置本体Aを支持する如く構成している。図示例では、各前部のリンク14a ,14c をそれぞれ装置本体A前部両側より垂設した固定アーム4,4の下端部に軸着し、また、各後部のリンク14b 14dをそれぞれ装置本体A後部両側より垂設したリンク14e ,14e の下端部に軸着している。従って、これら各リンク14a 〜14e により各駆動車輪2a,2b及び各全方向走行車輪3a〜3dが走行面の凹凸或いは段部等に対応して上下動をして無理のないスムーズな走行を可能にしている。
【0032】
また、各駆動車輪とその前後の全方向走行車輪とを同速度での回転が可能に伝達機構を介して連繋させている。図示例では、左前部全方向走行車輪3aと左駆動車輪2aとの間及び左駆動車輪2aと左後部全方向走行車輪3cとの間にそれぞれチェーン9を掛け渡して左駆動車輪2aと前後の左前部全方向走行車輪3a及び左後部全方向走行車輪3cとが同速度で回転する如く構成している。同様にして右駆動車輪2bと右前部全方向走行車輪3b及び右後部全方向走行車輪3dとが同速度で回転する如く構成している。
【0033】
この場合の各全方向走行車輪の構成も上記図1の実施例の所で説明したものと同様であり、また、各駆動車輪の速度制御機構も上記実施例の所で説明したものと同様のものが使用できるためその部分の図示及び説明を省略する。
【0034】
本請求項4発明の走行装置1も、駆動車輪2と、全方向走行車輪3とを備えている。この場合も駆動車輪2は左右一対設けており、同様に相対的に速度を変えられる如く構成している。
【0035】
また、全方向走行車輪3は上記した如き特殊構成をなし、また、各駆動車輪間中央の前方又は後方に配置して三輪車形態の本発明走行装置を現出し、或いは、各駆動車輪間中央の前方及び後方の両方にそれぞれ配置して四輪車形態の本発明走行装置を現出するものである。また、各駆動車輪間の車軸中央部に設けた差動機構により平均化した各駆動車輪の回転速度を伝達機構を介して同速度の回転が可能に連繋する如く構成している。
【0036】
図6は三輪車の形態の一例を示す。図示例に於いて、左右各駆動車輪2a,2bは装置体Aの後部両側より垂設した固定アーム4の下端部に軸着させており、また、全方向走行車輪3は装置本体Aの前部所定位置より垂設した固定アーム4の下端部に軸着しており、全方向走行車輪3を左右各駆動車輪間中央の前方に配置している。
【0037】
また、上記差動機構は公知のものが使用でき、例えば図7に示す如く、差動機構15は各駆動車輪を結ぶ車軸17を中央部で分割し、分割した左駆動車輪2aの車軸17a の先端に設けた傘歯車18a と右駆動車輪2bの車軸17b の先端に設けた傘歯車18b とを、ボックス19内に回動可能に突設した一対の傘歯車18c ,18d に歯合させてボックス19を各駆動車輪2a,2bの平均化した回転速度に回転させる如く構成している。そして、このボックス18の回転を伝達機構としてのチェーン9を介して全方向走行車輪3に伝達する如く構成している。
【0038】
この場合の各全方向走行車輪の構成も上記図1の実施例のところで説明したものと同様であり、また、各駆動車輪の速度制御機構も上記実施例のところで説明したものと同様のものが使用できるためその部分の図示及び説明を省略する。この場合にはサスペンションがなくても二つの駆動車輪が必ず接地するメリットがある。全方向走行車輪の駆動方向が旋回する円の駆動方向となり、路面との滑りが生じることなくスムーズに旋回可能となる。
【0039】
図8は四輪車の例を示す。この走行装置1は、各々個別の速度制御が行える左右一対の駆動車輪2a,2bと、各駆動車輪間中央の前方及び後方に配置させた前後一対の前部全方向走行車輪3e及び後部全方向走行車輪3fと、環状フレーム20とを備えている。
【0040】
この場合の各全方向走行車輪3の構成も上記図1の実施例の所で説明したものと同様であり、また、各駆動車輪2の速度制御機構も上記実施例の所で説明したものと同様のものが使用できるため省略する。また、環状フレーム20は、両側前後方向中間部の相対向する位置をそれぞれ上下方向の屈曲が可能に形成するとともに、両屈曲部分21を上記各駆動車輪2で屈曲可能に支持し、且つ、前後中央部を上記各全方向走行車輪3で支持している。
【0041】
図示例では、環状フレーム20を、両駆動車輪2に開口部両端を軸着して駆動車輪前方へ延設した半環状の前部フレーム20a と、両駆動車輪2に開口部両端を軸着して駆動車輪後方へ延設した半環状の後部フレーム20b とで構成している。また、前部の全走行車輪3eは前部フレーム20a の前部所定位置より垂設した固定アーム22の下部に軸着させており、後部の全方向走行車輪3fは後部フレーム20b の後部所定位置より垂設した固定アーム22下部に軸着させている。
【0042】
また、各駆動車輪2間の車軸中央部に設けた差動機構15により平均化した各駆動車輪2の回転速度を伝達機構を介して上記各全方向走行車輪3に連繋している。差動機構15は上記した図6の実施例で説明したのと同様のものが使用できる。また、伝達機構としては、前部の全方向走行車輪3eと作動機構15のボックス19との間及び後部の全方向走行車輪3fとボックス19との間にそれぞれチェーン9を掛け渡している。
【0043】
更に、上記環状フレーム20の各前後部いずれか一方中間位置の両側部分に於いて固定アーム4を介して装置本体Aを支持するとともに、他方の中間位置の両側部分に於いてリンク14を介して装置本体Aを支持している。図示例では、装置本体Aの前部両側よりそれぞれ垂設した固定アーム4の下端部を前部フレーム20a 両側中間部にそれぞれ軸支しており、また、装置本体Aの後部両側よりそれぞれ垂設したリンク14の下端部を後部フレーム20b 両側中間部にそれぞれ軸支して構成している。従って、上記図4に示す実施例と同様に走行面に凹凸や段差があっても各車輪がそれによって上下動し充分対応してスムーズな走行を可能にしている。
【0044】
【発明の効果】
以上説明した如く、本請求項1発明の走行装置は、既述構成としたことにより、シンプルな構成で、低コストで不整地や段差の走行が可能で、路面を傷つけることのない走行車が可能となり、建築現場の仕上げ工程での資材運搬や、屋内で使用できる電動車椅子へ適用することが可能である。
【0045】
また、請求項4発明の走行装置に於いて三輪車形態にした場合には、上記効果に加え、サスペンションがなくても二つの駆動車輪が必ず接地する利点を兼ね備えている。また、四輪車にした場合には、その場旋回が極めて容易となり、狭隘地などでの走行がし易くなり、また、車輪数が多いため輪荷重が小さくなり、段差乗り越えなどの不整地走行性能がより高まる利点を兼ね備えている。
【0046】
また、各々個別の動力を介しての速度制御により相対的に速度を変えられる左右少なくとも一対の駆動車輪を設けたものにあっては、人が装置本体上に乗っての自動操作が可能となる。
【0047】
また、単一動力により駆動するとともに、車軸中央部に差動機構を設け、前後方向に対する変角方向への人力による推進力に対応させて相対的に速度を変えられる左右一対の駆動車輪を設けたものにあっては、人が走行装置に付いていってその直進、旋回操作を容易におこなえることが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a traveling device, and more particularly to a skid steer traveling device capable of smoothly turning.
[0002]
[Prior art]
The skid steer method used in multi-wheeled rough terrain vehicles and crawler-type construction machines can change the direction by simply changing the rotation speed of the left and right wheels or crawlers, and does not require a complicated steering system. There is an advantage that it can be rotated on the spot. In addition, driving on all the wheels has a high level of rough terrain driving ability, but there is a demerit that the side surface is slipped between the road surface and the wheel or the crawler during turning, and the turning is not smooth and the road surface is damaged.
[0003]
In addition, wheelchairs that have a free caster on the front wheel have the advantage of being able to turn on the same wheel while changing the rotational speed of the left and right wheels, just like skid steer. However, since the free caster cannot be driven, there is a problem that the running ability on rough terrain is low.
[0004]
Furthermore, in the case of a wheel-type vehicle that drives all wheels, generally, the direction of the steered wheels is changed for turning, and the turning radius cannot be reduced. Moreover, since it is necessary to provide both a steering mechanism and a drive mechanism, there exists a problem that a mechanism is complicated and cost becomes high.
[0005]
A crawler-type mechanism that is capable of turning without causing side-sliding is known (for example, see Patent Document 1), and simple by using a drum-type roller. There has been proposed a wheel-type moving body capable of driving a steered wheel with a simple configuration (see, for example, Patent Document 2).

[Patent Document 2]
JP 2001-63645 A (page 2-8, FIG. 1)
[0007]
[Problems to be solved by the invention]
The former is a crawler-type endless track with free rollers arranged so that it can move in the lateral direction, and it can be swiveled without slipping, but this mechanism has no lateral restrictions, so the same thing can be used. It is necessary to control in combination of three or more, the manufacturing and control methods are complicated, and it is not suitable for moving on rough terrain. The latter uses a drum-type roller to enable driving of the steered wheels with a simple configuration, but requires a separate steering mechanism and increases costs.
[0008]
The present invention has been made in view of the above points, and proposes a simple and low-cost traveling device that can be smoothly turned without skidding, can travel on rough terrain without damaging the road surface. .
[0009]

A traveling device is characterized in that a plurality of free rollers are rotatably supported inside and a ground contact surface is formed by the free rollers.
