Blade motion reduction
First Claim
1. An articulated dozer, comprising:
- a first chassis portion;
a second chassis portion;
a first A-frame;
a second A-frame;
a C-frame having a first side and a second side;
a first controlling cylinder;
a second controlling cylinder;
a grader blade having a first blade side and a second blade side, the first A-frame attached to the front chassis portion such that relative lateral movements are constrained and relative vertical movements increase with increased distance from a point of articulation, the blade being operatively attached to the C-frame, the C-frame being operatively attached to the A-frame, the first controlling cylinder connecting the first blade side to the first chassis portion, the second controlling cylinder connecting the second blade side to the first chassis portion.

Abstract
An articulated loader has an articulated chassis and corresponding A-frames. The points of the A-frames face each other. 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 tracks are independently suspended. The C-frame and blade are mounted to the first A-frame while the controlling cylinders are mounted to the front chassis portion. This allows the blade to follow the tracks or ground and yet stabilize its motion.
