Transmission units offer increased torque for high-mileage vehicles

19 November, 2015

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

The Hydrotrac GFT series 8000 is ideal for use in open or closed hydraulic circuits and comes in nine different sizes with a torque range of 10 to 130kNm, ensuring the needs of almost any high-mileage vehicle are met.

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

As an optional extra, versions 8120, 8130 and 8150 can be retrofitted with a dynamic multi-disc brake, which is not only 75 per cent lighter than traditional brakes, but ensures stringent safety criteria can be met for self-propelled equipment.

In addition, the multi-disc brake is located inside the gearbox and is therefore protected from grime and the weather to keep maintenance costs to a minimum.

Alex King, industry sector manager for UK power transmissions at Bosch Rexroth, said: “Mechanical planetary gearboxes are generally used in very tough conditions, so end-users are looking for a solution that can operate efficiently in difficult environments, whilst keeping maintenance to a minimum.

“The Hydrotrac GFT series 8000 not only offers increased performance levels to meet the needs of a wide range of high-mileage applications, but its compact design and fast configuration keep installation quick and simple.”
