MRD integrated motor active frame (suitable for luxury high-end cars)

MRD integrated motor active frame (suitable for luxury high-end cars)

Magnetorheological damper integrated motor active suspension is an advanced suspension system that combines semi-active damping regulation and fully active force control, aiming to achieve multi-dimensional vibration suppression and dynamic attitude optimization through electromechanical integration. Its core lies in utilizing the fast damping adjustment capability of magnetorheological dampers, combined with the precise force output of motor-driven active actuators, breaking through the passive response limitations of traditional suspensions, and suitable for scenarios with extremely high requirements for handling, comfort, and energy efficiency (such as high-performance electric vehicles, luxury cars, and special vehicles).

The magneto rheological damper is physically connected in parallel with the motor actuator, acting together on the suspension strut (such as between the unsprung mass and the vehicle body)

Parallel type

The motor actuator is connected in parallel to the outside of the magneto rheological damper, directly driving the movement of the piston rod (customized design required).

Energy recovery

The motor recovers vibration energy during suspension vibration and assists in outputting active power during discharge (applicable to new energy vehicle models).

Multidimensional control of degrees of freedom

Simultaneously adjust damping force and active force, covering the entire frequency range of vibration (0.1-50Hz).


Ultimate Performance Performance

Comfort: The high-frequency vibration attenuation rate is increased by 30% -50%, and the RMS value of vehicle acceleration is reduced by 40%.

Handling: The roll angle is reduced by 50% -70%, the fluctuation of tire ground pressure is reduced, and the cornering limit is increased.


Energy efficiency:

Motor actuators can recover vibration energy (such as unsprung mass kinetic energy), reducing the net power consumption of the system.

The low current characteristics of magnetorheological dampers reduce the burden on electrical systems.


Active adjustment of vehicle height

Lift and lower by extending and retracting the motor actuator (such as lifting the chassis in off-road mode).
