초록

An articulated loader has an articulated chassis, two A-frames, and four track assemblies. A narrow portion each of the A-frames faces a narrow portion of the other A-frame. The articulated chassis includes a front portion and a rear portion. Likewise, there is a front or first A-frame and a rear or second A-frame. The A-frames are connected to the overall chassis at points close to but offset from the point of vehicle articulation via ball joints and via hydraulic suspension cylinders toward the wider portions of the "A"s. The chassis of the vehicle is ...
