The VARIPOWER transmission in the SCORPION 1033, 741, 736, 732 and 635 has now been replaced by the new VARIPOWER 2 twin motor, designed and manufactured exclusively for CLAAS. The compact drive unit from the JAGUAR forage harvester promises a long service life, improved drive efficiency and reduced noise levels.
VARIPOWER 2 comprises two hydrostatic motors inside a compact housing which share a common shaft and swash plate. Both motors have a maximum swivel range of 23 degrees, with both traction units controlled by a common distribution unit.
As before, the operator can select three driving ranges – 0 to 15 km/h, 0 to 30 km/h and 0 to 40 km/h – with the simple press of a thumb. The top speed is reached at a reduced, fuel-saving engine speed.
VARIPOWER 2 transfers just as high torque to the wheels as the previous VARIPOWER transmission. The simple, compact design, which dispenses with the need for transfer gears, ensures a high level of wear tolerance and long service life. The new feature is that the housing oil is continuously extracted from the drive housing by a powerful Venturi tube, which significantly reduces churning losses when driving at speed. This ensures maximum efficiency and low fuel consumption even on fast road journeys.
