| The magneto-spring
suspension unit combines a positive/negative "magneto-spring"
with spring properties derived from the repulsion force of similar
poles and the attraction force of opposite poles of a set of
magnets; in combination with a metal spring assembly, it achieves
vibration damping within a very short stroke of 40mm. The unit's
damping properties can be fine-tuned by adjusting the magnets'
positions, the metal spring's force, etc. in response to the
type of vibrations to which it will be exposed. |

As with a typical spring,
the unit combines a torsion bar with linear load properties and
a magneto-spring with non-linear load properties to create a "spring-zero"
state of consistent load, independent of the amount of flexure.
The "Spring-zero" condition accomplishes phase control
and exhibits effective damping to curb vibration. |

This suspension unit's design incorporates
permanent magnets, so doesn't require a power source; it is extremely
durable, as it is virtually maintenance-free. |

Due to the phase control provided
by the magneto-spring, this unit absorbs vibration across a much
smaller stroke compared to a damper that the converts it to heat
energy to be absorbed. Absorption of the same vibration is accomplished
within half the stroke length of a traditional damper, which makes
the unit's extremely compact design possible. |

The magneto-spring used
in this suspension unit incorporates magnets facing each other left
to right and separate magnets in between that move vertically; in
this manner, reaction force and attraction force create an upward
spring force on the upper side of the neutral seated position, and
also create a downward spring force on the lower side of the neutral
position. |

| The magneto-spring suspension
unit is currently available as an option on the Mitsubishi Canter
light-duty truck seat for increased vibration reduction. |
