The A6VM improves driving and steering behavior of pavers and crawler-type machines, such as loading tractors and bulldozers, with precise control and power usage for applications with high-feed requirements. Combined with the Series 40 A4VG axial piston variable pump in closed-circuit operation, the A6VM motor is ideal for hydrostatic travel drives in mobile equipment.
The Series 71 A6VM axial piston variable motor achieves high power density by increasing nominal pressure, rotational speed, and specific displacement. The nine-piston motor efficiency has improved, particularly with small swivel angles. The motor ensures smooth low-running speed operation at very low output speeds over the entire swivel angle range. The motor‚â€™s starting behavior is also improved. Its ability to switch to the zero position also allows the addition of various drive functions.
The sealing points of the threaded connections are designed to use seal rings. The improved temperature behavior and reduced case pressure cuts down on wear and increases service life, even though the main case dimensions remain the same as the previous series. Speed and temperature sensors can also be connected.
