Direct load path structure

DIRECT LOAD PATH STRUCTURE Abstract of the Disclosure 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 suspended above the first and second A-frames. The vehicle is propelled along the ground by tracks that are independently suspended. The bulk of the load from the blade, i.e., the blade load, is transferred directly to the tracks via the first and second Aframes; the first and second ball joints and pivot connections between the first and second A frames and the track frames for each track assembly. Thus the chassis sees little of the blade load allowing for a lighter, less bulky vehicle. i:iz -~1 -I o e
