Description
ースの内部に収容すると共に、同旋回用無段変速機はミッションケースの横一側の外壁部に集中装着して、その入力軸をミッションケース内部の前後進クラッチの出力側に連動連結するとともに、出力軸は正逆回転分割機構を介して前記左右遊星歯車機構に連動連結して構成したため、ミッションケース内の伝動系をコンパクトにかつ合理的にまとめて収容することができ、直進動力伝達系の無段変速機を省略したことと相俟って、伝動系を簡素化することができて、大幅な製造コストの低減を達成することができ、また、ステアリングホイルを操作しなくても、前後進クラッチの切換と同時に旋回用無段変速機の出力回転方向が切り換わり、ステアリングホイルの操作方向と作業車の旋回方向とが一定の関係を保持し、ホイルタイプの車両の操向操作と略同様の感覚で旋回操作を行うことができる。

Claims (1)
- エンジン(23)に直進動力伝達系(M)と旋回動力伝達系(H)とを介して左右遊星歯車機構(74a,74b)を連動連結して、同左右遊星歯車機構(74a,74b)により直進動力伝達系(M)と旋回動力伝達系(H)の回転速度を合成して、合成回転速度にて左右走行装置(1a,1b)を個別に駆動すべく構成し、直進動力伝達系(M)は歯車式変速機構により構成する一方、旋回動力伝達系(H)にはステアリングホイル(21)の操作により出力回転速度を変更可能とした旋回用無段変速機(54)を設けた作業車において、上記直進動力伝達系(M)と旋回動力伝達系(H)は旋回用無段変速機(54)を除いてミッションケース(40)の内部に収容すると共に、同旋回用無段変速機(54)はミッションケース(40)の横一側の外壁部に集中装着して、その入力軸(55)をミッションケース(40)内部の前後進クラッチ(50a,50b)の出力側に連動連結するとともに、出力軸(72)は正逆回転分割機構(75)を介して前記左右遊星歯車機構(74a,74b)に連動連結して構成したことを特徴とする作業車。
