The patented DCC allows the driveline system to engage and disengage the drive axles while conserving energy and maintaining on-road and off-road capabilities. A comprehensive white paper on this Electro-Mechanical E-axle Disconnect solution and its technologies is available at AmstedAuto.com. The controllable disconnect clutch and actuation technology has full disconnect and locking engagement, with additional aptitude in controlled bi-directional one-way-clutch operation. It can be combined with multi-speed shift, hill-hold, and park-lock features to create multi-functional clutch solutions for this next generation of EV drivetrains.
Another important consideration for Amsted Automotive was to ensure the system provided quick and reliable shifts between power, regeneration, and coasting modes. And design flexibility had to be adaptable at multiple locations between the eMachine and the wheels.
There are electric pickups currently in production utilizing Amsted Automotive DCC technology, which can extend an EV’s range by 10-20%, depending on the application.

The group combines design and engineering expertise, strategically aligned to be a nimble leader in advanced metal-forming and powder metal manufacturing with electro-mechanical clutch design capabilities for electrified propulsion solutions and builds on Amsted Automotive Group’s integral role in global advanced automatic transmissions designed in North America, Europeand Asia.
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, the EV range can be extended by 10-20%, depending on the application.
