Primary Semi-Active Suspensions Contact Us

Originally developed for military applications, MR semi-active suspension systems have since been demonstrated on other industrial applications with the verified benefits of improved ride comfort, vehicle stability, safety, speed, productivity and durability. Each primary suspension system consists of a set of semi-active dampers, a control unit, sensor network, and wire harness.

Customized Semi-Active Suspension Solutions

LORD can also develop new solutions with unique product requirements for applications requiring instantaneous and precise control of variable force.

Benefits of LORD MR Semi-Active Suspension Systems

Customized controllable damping significantly improves vehicle ride comfort, handling and safety.

  • Improved driver responsiveness, efficiency and pleasure
  • Reduced operator fatigue and risk of injury
  • Improved vehicle stability for safe maneuverability at higher speeds
  • Easily integrated with other vehicle electronic systems (braking, steering) to enable sophisticated vehicle dynamic control capability
  • Fail-safe (becomes a passive damper) or fail-firm (becomes rigid) design options if electrical power is lost
  • Better protection for cargo or goods
Simple electro-mechanical design is easy to integrate, improves reliability and reduces total cost.
  • No additional packaging space required versus conventional passive dampers
  • No maintenance required
  • Reduced wear on suspension and drivetrain components
  • Low power requirements (typically less than 5A)
  • Broad operating temperature range (-40°C to 120°C)
