Crawler-type working machine
The invention provides a crawler-type work machine. In a bulldozer (1), when the operation amount of a direction operation lever (35) is greater than a first predetermined amount (TH1) and less than a second predetermined amount (TH2), left and right steering clutches (40L, 40R) are engaged, left and right steering brakes (50L, 50R) are released, and a turning motor (80) is driven such that the number of revolutions of an inner output shaft (60IN) is lower than the number of revolutions of an outer output shaft (60OUT) as the operation amount of the direction operation lever (35) increases. When the operation amount of the direction operation lever (35) is equal to or greater than a second predetermined amount (TH2), the controller (100) reduces the engagement rate of the inner steering clutch (40IN) and brakes the inner steering brake (50IN).
本发明提供一种履带式作业机械。推土机(1)在方向操作杆(35)的操作量比第一规定量(TH1)大且比第二规定量(TH2)小的情况下，使左右转向离合器(40L、40R)卡合，使左右转向制动器(50L、50R)释放，并使内侧输出轴(60IN)的转数随着方向操作杆(35)的操作量增大而比外侧输出轴(60OUT)的转数低地使转弯马达(80)驱动。控制器(100)在方向操作杆(35)的操作量为第二规定量(TH2)以上的情况下，使内侧转向离合器(40IN)的卡合率降低，使内侧转向制动器(50IN)制动。
