Amsted Automotive’s Controllable Mechanical Diode (CMD) offers unmatched efficiency, durability, and seamless operation for internal combustion engine (ICE), hybrid, and electric propulsion systems. Many OEMs chose for their best-selling vehicles to use Amsted Automotive’s CMD because they combine the best attributes of traditional Mechanical Diode (MD) technology and selectable one-way clutches (SOWCs).
A CMD is a selectable one-way clutch (SOWC) system that enables active, on-demand engagement and disengagement of torque transfer within propulsion systems.
Key Benefits:
- Supports high torque density applications.
- Improves overall system efficiency to increase fuel economy and/or battery range.
- Requires less packaging space for compact system integration.
- Features electromechanical or hydraulic actuation for precise engagement and disengagement.
- Enables full system integration by reducing complexity and improving reliability.
- Optimized for energy regeneration and power transfer in electrified propulsion systems.
- Decreased system response time for smooth transitions between driving modes.
- Aluminum compatibility enables cost savings and mass reduction.
Applications:
- Shifting Elements
- Driveline Disconnects
