At this year’s Agritechnica, Bonfiglioli launched a compact hydraulic wheel drive unit designed specifically for the agricultural industry. The new 600WT drive series integrates a new axial piston motor developed with agricultural vehicles in mind.
A Bonfiglioli spokesman said, “The 606WT wheel drive perfectly combines proven mechanical systems with a new integrated 68cc/rev swashplate motor and thus represents the best choice for agricultural machinery, having closed-loop circuits such as self-propelled sprayers.”
This drive unit, which provides an output torque of up to 17,000Nm, integrates the Th68 axial piston motor designed for a continuous pressure of 450 bar and a maximum volumetric flow rate of 160 l/min. It is also capable of zero displacement.
Additional features of the 606WT drive units are the two-position hydraulic displacement
control, an electric proportional continuously variable displacement control, and the built-in speed sensor. Mechanical gear disengagement, an integrated parking brake, and a spring-actuated hydraulically released or dynamic brake, which includes an inspection port, are also available as options.
