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.

A method of reducing fuel consumption in a machine with an internal combustion engine. The machine has a hybrid mode in which the engine is used for simultaneous ground propulsion via a torque convertor and hydraulic implement propulsion via a hydraulic pump. The engine controller uses a first engine map that defines primary operating constraints. The method comprises: obtaining an initial torque limit from a torque limit profile providing operating constraints that fall within the primary operating constraints. The method further comprises: implementing a torque limit that corresponds to the initial torque limit value such that in an event that a torque demand exceeds the torque limit then the engine speed will drop below the desired engine speed. The method further comprises, in an event that torque converter speed ratio between engine and ground propulsion drops below a speed ratio threshold, removing the torque limit profile and reverting to primary operating constraints.

The invention provides a push wheel driving type ground sweeper which is composed of ground sweeping brushes, arc shovels, abutting plates, brush wheels, spindle belt pulleys, dust scraping brushes, a box body, a storage box, wheels, change wheels, belt pulleys and a pushing handle, wherein the ground sweeping brushes are fixed on the brush wheels along the radial direction; the widths of the brush wheels can be determined as required; the brush wheels are fixed on the spindle belt pulleys; the arc shovels are used for guide surfaces for guiding the direction of the swept garbage; shovel ports of the arc shovels are formed in the positions, in contact with a top surface, of the brush wheels; a slope is formed at the rear end of each arc shovel, and an involute distance is formed between the slope and each ground sweeping brush; and when the ground sweeping brushes roll forward, garbage and dust can be swept backward. When the push wheel driving type ground sweeper is used, the pushing handle is held by hands to push the ground sweeper to move towards the ground with garbage and dust, and then the garbage can be swept by the ground sweeping brushes; and if the ground is not cleaned, the ground sweeper can be repeatedly pushed back and forth for several times.

An articulated loader has an articulated chassis and two 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 vehicle is propelled along the ground by tracks that are independently suspended. The A-frames are of approximate equal length along the axis of the vehicle and the ball joints are located as close as practical to the articulation joint. Thus, any vertical forces at the ball joints due to variations in tractive efforts for the vehicle tend to be equal and opposite in direction and to, therefore, minimize any chassis height variations.
