ZF presents its TraXon automatic transmission system for medium and heavy special vehicles and mobile cranes.

  • Features modular concept
  • Offers higher torques without compromising the power-to-weight ratio
  • Provides higher gear spread while at the same time improved noise quality
  • Can be driven by a dry clutch or torque converter clutch, or can be combined with an engine-dependent PTO depending on the application
  • Features compact dimensions with a splitter group, main group, and range change group, as well as two countershafts and one main shaft
  • Transmits torques above 3,000 Nm, making it well suited for vehicles with a gvw of 72 T
  • Available with 12 or 16 speeds, and available as Direct Drive or Overdrive versions
  • Overdrive version features particularly long ratio of the highest gear
  • All versions have very high transmission spacing, enabling the driver to maneuver vehicle in balanced and comfortable way without causing wear due to excessive load on the clutch
  • Introduction of new gearing design, innovations for housing, and integration of an anti-rattling damper enables average noise reduction of 6 dB compared to AS Tronic transmission
  • Allows for use of two additional reverse gears, or total of four reverse gears for longer, quicker reversing
  • DirectDrive version provides efficiency of about 99.7%
  • Includes Concentric clutch release unit, ConAct, featuring push-type clutch design protected inside bell housing
  • Modular design enables combination with three starting or shift modules
  • Can include dry single-disk or – for particularly high-torque applications – double-disk clutch which is robustly designed
  • Can be combined with torque converter clutch for use in heavy road tractors and heavy mobile cranes
  • Equipped with optional secondary retarder with a braking torque of 4,000 Nm, the ZF-Intarder, which provides advantages for brake operations at speeds higher than 25 km/h
  • Standard software platform for control unit draws on a number of sensors to determine pitch, direction of rotation, or speeds, enabling functions such as the anticipatory shifting strategy, rolling function, and more comfort when maneuvering or starting
  • Anticipatory GPS-based driving strategy PreVision GPS provides opportunity to link up transmission with GPS data and digital map material
  • PreVision GPS prevents gearshifts that may be unnecessary within the context of the terrain 
  • Rolling function for slightly sloping roads causes transmission to o out of gear, decoupling the driveline during the rolling phase and the engine to run idle, avoiding possible drag losses to save on fuel and emissions
  • Topography-based control unit immediately detects steep slopes and applies engine and transmission brake instead of rolling function in order to preserve service brakes
