osch Rexroth’s HYDROTRAC GFT 8000 gearbox enables an ap-

proximate 10

% increase in drive train performance

for larger

mobile working machines. Launched earlier this year and now

available from Hytec, a Hytec Group Company, these transmission

units are based on a modular design. Ideal for use in harsh, rugged

environments including African mining operations, they have two-

and three-stage combined planetary gearing with axial piston motors

to match the needs of heavy and bulky mobile working machines

such as trucks and excavators.

An optional internal brake reduces the installation space needed, but

adheres to the safety specifications for worldwide roadworthiness cer-

tification. The mechanical planetary drives in these transmission units

transfer the torque from the hydrostatic drive to the wheels or tracks.

Bosch Rexroth uses the newest versions of variable axial piston motors

or fixed-displacement axial piston motors, which operate in either an

open or closed circuit.

Travel capacity is significantly improved as the higher fluid capacity of

the motors and the higher hydraulic pressures, along with the exact

matching with the two- and three-stage planetary drives, boost torque,

and therefore performance, by approximately 10%.

At the same time, vehicle manufacturers can sometimes select a

smaller nominal size to achieve the same output. This saves instal-

lation space.

The optional integrated multi-disk brake inside the unit requires min-

imal maintenance and is designed for protection against soiling, an

added advantage when working in demanding environments. Also,

when used in conjunction with Bosch Rexroth’s High Level Braking

System, they satisfy the exacting safety requirements for speeds up

to 50 km/h.

All units are delivered as complete assemblies, ready for installa-

tion, and vehicle manufacturers can select a smaller nominal size to

achieve the same output, which saves on installation space. Owing to

the platform’s modular concept, OEMs can vary the drive torques and

transmission rations, closely matching them to the vehicle used.

Two models in the 8000 series, which achieve nominal torques of

20 and 30 kNm, are available off-the-shelf, and an additional seven

models are currently being rolled out to the market.
