TPT 11 Transaxle

ZF has introduced the TPT 11, a powershift transaxle in the 85 to 115 hp power range.

December 18, 2013

With the TERRAPOWER Transaxle (TPT) 11, ZF is laying the cornerstone for the modular expansion of its ever important and popular transmission range for tractor power ratings between 85 and 115 hp.

Includes fast responding and conveniently matched four-way powershift facilitated by proportional valve control
Smooth acting shuttle shift (Power Shuttle) and PTO clutch operates free of jerks and shocks, and starts up under closed-loop control dependent on the load
Offers 32 forward and 32 reverse gears, as well as four PTO speeds
Divided into 16 gears in the field-work range and 16 gears in the road-driving range, fine gradation of transmission ratios is provided for each type of deployment
Fine gradation combined with ability to adapt selected transmission ratio up to four times under load ensures work is always carried out at the optimum speed
Integrated pump drive helps increase energy efficiency by powering both a controllable axial piston pump and tandem pump simultaneously with low losses, ensuring sufficient hydraulic power for all applications
Comfort features including Comfort Shift, Intelligent Power Shift (IPS) and Speed Matching are available on request, as is a ground speed PTO
In-line design places input shaft and center of rear axle at the same height, enabling production of vehicles with lowest possible center of gravity and reduced total height
Proportional valve control allows each switching element to have its own proportional valve for individual pressure control for each single clutch
Switching behavior is independent of temperature and load status of the transmission
Includes integrated overload protection
Increased transfer capacity of clutches provide an increased reversing speed
Load-dependent "electronic" control of the system (Load Sensing) creates closed-loop control for optimum adaptation to actual load conditions, avoiding sudden stresses
Load-dependent control ensures powershift or run-up process of PTO is more comfortable, as well as prevents possible overload
