Amsted Automotive Group has developed a Dynamic Controllable Clutch (DCC), an electro-mechanical eAxle disconnect system, which addresses the need for new torque-management solutions for EVs, providing seamless shifting technology and performance, while significantly extending the battery range, the company says.

Amsted Automotive adapted the technology for EVs, since traditional clutches are not conducive to the demands of electric propulsion systems. The patented DCC, as an electro-mechanical eAxle disconnect solution, enables the driveline system to efficiently engage and disengage rear electric drivetrains from their drive eAxles while conserving energy and maintaining on-road and off-road capabilities, the company says. DCC uses electric actuation to create substantial packaging and system efficiencies by eliminating complex hydraulic systems. It magnetically latches in each state, significantly reducing the energy requirements to keep AWD and 4WD systems engaged. This application of mechatronics enables shift times of less than 20 milliseconds. Additionally, EV range can be extended by 10-20%, depending on the application, the company says.
