The Amsted-specific innovations include:

  • Torque management systems using unique Amsted Controllable Mechanical Diodes (CMD) and Mechanical Diodes (MD)
  • Production Dynamic Controllable Clutch (DCC) and Electro-Mechanical E-Axle Disconnect that enables seamless and reliable AWD and 4WD shifting in EV applications
  • Production 10-speed transmission featuring Amsted CMD clutch technology
  • An innovative wheel-end disconnect system designed for commercial vehicle applications

The event is expected to draw more than 500 exhibitors and have over 1,100 booths. Engineers from global auto companies can see the Amsted technology and systems in booth #431.

The Amsted DCC and Electro-Mechanical E-Axle Disconnect have been in production vehicles since 2021. This technology offers significant advantages over dog-clutch style clutches including smooth and consistent shifts without the possibility of blocked shifts, simplified system controls and additional functionality. Calibration is also easier, reducing engineering loads. It can also improve EV driving range up to 10 percent.

Amsted clutch technology can also be found in prominent Japanese automotive manufacturer's production vehicles. These systems use Amsted CMD and MD technology, including a forward direction one-way clutch for seamless shifts between First and Second gears, and controllable reverse direction clutch for engine braking and Reverse gear. This reduces drag and friction, and the system also minimizes packaging space and mass.

Amsted's global business units provide expertise in product, process, and manufacture, resulting in unmatched innovation and performance.
