Punch Powertrain Disconnect Control Unit DCU

The DCU handles engine disconnect in hybrid and electric drivetrains.

Compared to conventional electromagnetic disengagement mechanisms, it reduces energy consumption by up to 18%.

It is completely isolated from the transmission system with its own independent lubrication chamber, which simplifies integration and reduces contamination risk. It also uses an end-face tooth structure for high torque transmission capacity and enhanced torque adaptability.

It is a bistable electromagnetic design, meaning it holds its engaged or disengaged state without continuous power draw. For hybrid and electric architectures where disconnect frequency is high, that matters.
