Integrale DFT™

Integrated with Gearbox and Differential

After the development of the Hi-Perm-Mag series, Solaredge e-Mobility division's idea was to couple a transmission to it. The transmission consists in a system with self-locking differential engaged using fixed gears installed in a specially designed aluminum housing.

The transmission gears have ground teeth and have been treated to lower noise emissions and increase system efficiency.

Integrale DFT™


Features

Since the frame connection system is universal, the Hi-Perm-Mag DFT is also suitable for vehicles already in circulation and with different motorizations.

The auto-locking differential is equipped with increased gears and with the recovery of wear system that guarantee a long life.

The differential above mentioned has been developed by IET to permit swift maneuvering at low speeds with an increase in grip during cornering:

  • Better drive in curve
  • Better torque/speed curve
  • Swift maneuvering at low speed
  • Consumption optimization
