CRAWLER TYPE WORKING MACHINE
To provide a crawler type working machine capable of inhibiting power loss of an engine being turning slowly.SOLUTION: When an operation amount of a steering lever 35 is larger than a first predetermined amount TH1 and smaller than a second predetermined amount TH2, a bulldozer 1 causes right and left steering clutches 40L and 40R to engage with each other, releases right and left steering brakes 50L and 50R, and causes a swivel motor 80 to drive so that a rotation speed of an inner output shaft 60IN becomes further lower than a rotation speed of an outer output shaft 60OUT as the operation amount of the steering lever 35 increases. When the operation amount of the steering lever 35 is equal to or greater than the second predetermined amount TH2, a controller 100 reduces an engagement rate of an inner steering clutch 40IN and causes an inner steering brake 50IN to perform braking operation.SELECTED DRAWING: Figure 3
【課題】緩旋回中のエンジンの動力ロスを抑制可能な履帯式作業機械を提供する。【解決手段】ブルドーザ１は、操向レバー３５の操作量が第１所定量ＴＨ１より大きく第２所定量ＴＨ２より小さい場合、左右のステアリングクラッチ４０Ｌ，４０Ｒを係合させ、左右のステアリングブレーキ５０Ｌ，５０Ｒを開放させ、操向レバー３５の操作量が大きくなるに従って内側出力軸６０ＩＮの回転数が外側出力軸６０ＯＵＴの回転数より低くなるように旋回モータ８０を駆動させる。コントローラ１００は、操向レバー３５の操作量が第２所定量ＴＨ２以上である場合、内側ステアリングクラッチ４０ＩＮの係合率を低下させ、内側ステアリングブレーキ５０ＩＮを制動させる。【選択図】図３
