SOF - Shift On Fly
Function
The new Shift on Fly shifting concept enables the operator to change gears while moving without having to have selected the travel range beforehand. This was accomplished by modifying a 2-gear standstill transmission by adding a synchro component.

Required components:

A4VG variable pump and A6VM variable motor: Higher power density due to increased pressure up to 500 bar
SOF transmission: Compact design for small footprint
BODAS hard- and software components for Shift On Fly: Flexible due to modular construction of the BODAS system.

Function SOF
Features of the respective system versions:

  • Shift On Fly with speed-based hydromechanical pump adjustment (DA):
    • The BODAS Electronics system with sensors and AGS (Automatic Gear Shifting) software are responsible for controlling the transmission
  • Shift On Fly with electrically controlled pump adjustment (EV):
    • The system is expanded to include the full-electronic travel drive, possible by means of the BODAS Electronics system modular design
    • Electronics makes it possible to directly affect the acceleration response and maximum speed, thereby allowing optimal and reliable adjustment of the overall driver response

  • Shift On Fly with automatic mode:
    • Fully automatic gear shifting
    • uses the actual drive conditions and driver intention to automatically determine the optimal shift characteristics
    • Individual adaptation of the automatic shift characteristics for each machine
