Description

明 細 書
技術分野
本発明は、 自動車等の動力伝達機構の差動装置に関する。 背景技術
従来より自動車等の車両において左右の車輪の駆動軸と一体に回転する 対峙させたかさ歯車間に数個のかさ歯車を挟み差動伝達させる差動装置が 公知である。 また片側の駆動軸が無負荷の状態の場合に反対の駆動軸に動 力を伝達出来なくなる事を防止する必要性からビスカスカツプリング等を 組み合わせ左右の駆動軸の回転差による滑り抵抗を発生させ差動回転を制 限をする差動装置がある。 発明の開示
本発明は、 差動装置自体に差動制限作用を有し、 差動回転の大きさに比 例して差動回転の制限力を生じる差動制限付差動装置である。 太陽歯車と 遊星歯車で構成する 2組の遊星歯車機構を歯車ハウジング内に仕切壁を挟 み対峙させて収納密封し、 左右の太陽歯車と各々一体に回転する駆動軸を 回転自由に歯車ハウジング外部に貫通させる。 歯車ハウジングは入力かさ 歯車と一体に組み立てられ入力回転を得て歯車ハウジング内の左右の遊星 歯車に公転を与える。
左右の遊星歯車の歯車嚙合い部の前後に、 作動液の流入排出のための空 隙部を各々設ける。 仕切壁を挟んで隣り合う左右の遊星歯車機構の空隙部 間は導通路にて通じ、 作動液の移動を可能にしている。 導通路は作動液の 流量を設定したオリフィス、 或いは使用条件に応じて流量を制御するため の制御弁を設置する事が可能である。 この密閉された歯車ハウジング内に 作動液を充填する。
歯車ハウジングに入力回転を与えると左右の遊星歯車は公転を得て自転 方向側の太陽歯車との嚙合い部の作動液に圧力を生じさせる。 左右の駆動 軸の負荷が等しい場合、 作動液は移動しないため遊星歯車は自転出来ずに 与えられた公転力はそのまま太陽歯車を回転させ左右に等しい駆動回転を 伝達する。 また左右の駆動軸が異なる負荷を受ける場合、 負荷の大きい側 の遊星歯車は太陽歯車上を負荷の差に応じて自転し作動液を排出し、 仕切 壁を挟んだ反対側の圧力の低い空隙部に導通路を通じて流出させる。 流出 した作動液は負荷の低い側の歯車嚙合い部に加圧作用して太陽歯車の回転 力を增加させ左右の駆動軸に回転差を生じさせる。 負荷の高い側の遊星歯 車機構はギアポンプとして、 また負荷の低い側の遊星歯車機構はギアモー タの作用をする状態となる。
また自動車等の車両において一方の駆動軸の負荷が極端に小さい、 例え ば片側の車輪が脱輪し地表から浮いたような場合、 他方の車輪が接地して いる負荷の大きい駆動軸側の遊星歯車機構は作動液を排出し負荷の小さい 駆動軸側に導通路より流出させるが、 導通路において作動液は流速の 2剰 に比例した抵抗を受けるため、 負荷の大きい側の静圧を上昇させ歯車嚙合 い部に作用して太陽歯車に静圧に応じたトルクを駆動軸に発生させる事に なる。 従って、 接地している側の車輪は回転力を得て車両を移動させる事 が出来る。 本差動装置は作動液の導通路における流速、 即ち差動回転に比 例した差動制限作用を生じさせる特性を有する。 また導通路に一定量以上 の作動液が流れると流路を閉にする制御弁を設置することで、 左右の駆動 軸を直結し一体回転する状態にさせることも可能である。
左右の負荷に差が生じると作動液は導通路を通じて移動するが歯車の回 転に伴い遊星歯車機構内を移動し、 排出作用の歯車嚙み合い部より流出し 導通路を通じて、 再び元の遊星歯車機構の流入可能な空隙部に戻り左右の 遊星歯車機構間を循環する事になる。
実施例では運転に伴う作動液の温度上昇による膨張等に対処するために 外部に設けた作動液タンクと接続させるため自動切替弁を本体ケーシング 蓋部に設置した。 自動切替弁は駆動軸の回転方向に応じて歯車嚙合い部の 低圧側の空隙部を差動装置外部と常に導通させ、 高圧側とは閉となる構造 とした。 或いは本体ケ一シング内と歯車ハゥジングとの空隙部に作動液を 充填し作動液タンクとして自動切替弁と導通させる方法も考えられる。 この自動切替弁と歯車嚙み合いの空隙部に通じる導通穴は、 歯車ハウジ ング蓋部に設けられた 2本の環状溝と通じ、 歯車嚙合い部の前方と後方の 2つの経路に分けて同一条件の空隙部と各々導通する。 この導通穴は数個 の遊星歯車が同一の作動液の圧力条件で太陽歯車と嚙み合い、 回転の伝達 作用を均一化する効果を生じさせる。 図面の簡単な説明
