Transmission units offer increased torque for high-mileage vehicles

The Hydrotrac GFT series 8000 is a rotating planetary gearbox developed by Bosch Rexroth to offer increased power density and torque for wheel and track driven equipment, such as subsea crawlers, bulldozers and agricultural sprayers.

The drive units feature a two or three-stage planetary gearbox with a bent-axis design axial piston motor, providing a compact transmission unit capable of saving space in wheeled and tracked vehicles.

The gearbox is suitable for use in open or closed hydraulic circuits and comes in nine different sizes with a torque range of 10 to 130kNm.

The new drive unit can be integrated with the existing Rexroth A6VE hydraulic motor, increasing power density and torques by approximately ten percent compared to previous versions.

As an option, versions 8120, 8130 and 8150 can be retrofitted with a dynamic multi-disc brake, which is not only 75 percent lighter than traditional brakes, but ensures safety criteria can be met for self-propelled equipment. The multi-disc brake is located inside the gearbox for maximum protection.
