Brogen OESTEA40000Z is a generation 1.6 heavy-duty electric drive axle designed for tractor and freight truck applications requiring extremely high torque density and robust durability under continuous heavy-load operation. It delivers up to 40,000 N·m of wheel-end torque through a combined architecture of a two-speed gearbox and integrated hub reduction, enabling strong low-speed pulling force and efficient high-speed cruising in a single compact drivetrain unit.
