Amsted Automotive Brings Revolutionary E-axle Disconnect Technology to EVs

E-axle Disconnect Technology

The Amsted DCC and E-axle disconnect technology allows for seamless engagement and disengagement of AWD and 4WD systems in electric vehicles.

Early 2021 marked the formation of the new Amsted Automotive Group, which combined Amsted Industries with two of its core Tier 1 automotive supply business units, Means Industries and Burgess-Norton. This innovative powerhouse got to work immediately on developing a revolutionary E-axle solution for electric pickup trucks and SUVs. Just one year later, the cutting-edge technology is now leading the advancement of EV propulsion worldwide.

The Dynamic Controllable Clutch (DCC), an Electro-Mechanical E-axle Disconnect system, addresses the need for new torque-management solutions for EVs, providing seamless shifting technology and performance, while significantly extending the battery range. Amsted Automotive adapted the technology for the customer’s EVs, since traditional clutches are not conducive to the demands of electric propulsion systems.

The patented DCC, as an Electro-Mechanical E-axle Disconnect solution, enables the driveline system to efficiently engage and disengage rear electric drivetrains from their drive axles while conserving energy and maintaining on-road and off-road capabilities. 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. A comprehensive white paper on the Electro-Mechanical E-axle Disconnect solution and its technologies is available at AmstedAuto.com.
