Fendt VarioDrive – the new drive train
The stepless Vario transmission has been setting worldwide standards in tractor drives for more than 20 years. Now a newly developed, comprehensive drive train with variable four-wheel drive takes the Fendt 1000 Vario to the top.
From Vario to VarioDrive
Fendt Vario means stepless, dynamic driving with plenty of pulling power for speeds from 0.02 to 60 km/h. The new drive on the Fendt 1000 Vario was specifically developed to exploit the high engine power in any situation, independent of ground conditions, and to keep speeds especially low. The solution: Fendt VarioDrive – the first drive train that drives both axles independently.
Power distribution through Fendt Torque Distribution
Conventional four-wheel drives usually have a fixed torque ratio between the front and rear axle. Fendt VarioDrive enables a variable four-wheel drive. The torque is distributed over two transmission outputs independently on both axles. With the help of an intelligently controlled four-wheel clutch, torque can be shifted between the axles according to need, Fendt Torque Distribution.
500 hp with variable four-wheel drive
The flexible torque distribution of the variable fourwheel drive is achieved through a T-piece, which is located between the hydraulic pump and the hydraulic motors for the front and rear axles. It acts as a hydrostatic differential between the axles and permits the oil flow between the pump and hydraulic motor to be adjusted freely. As a result, there is no tension. If needed, torque can be automatically shifted from one axle to the other via the intelligently controlled fourwheel clutch. Frictional loss and wear are reduced effectively.
New, larger high-capacity hydrostats with 370 cm³ ensure
very high transmission efficiency
Meisterwerk with grip
During field operations, torque is transferred flexibly to the axle. The result is tremendous pulling power. As the speed increases, a clutch completely decouples the front axle drive at approx. 25 km/h – this eliminates drag losses in the drive train and increases efficiency.
Tightest turning circle thanks to pull-in turn
Since there is no fixed drive ratio with the variable fourwheel drive, the front wheel drive can actively pull the tractor into the curve – this is the so-called “pull-in turn” effect. This effect alone reduces the turning circle in the field by up to 10 percent. VarioDrive minimises the otherwise usual tyre wear on the front tyres that is caused by cornering on firm substrates (specifications turning radius for standard tyres).
