Abstract
A suspension arm bushing provided in a vehicle includes coils. First magnetic viscoelastic elastomers are arranged at both ends in an axial direction of a housing, respectively, to sandwich the coils. A second magnetic viscoelastic elastomer is arranged in the housing so as to be sandwiched between the coils. A controller selectively switches directions of magnetic fields generated by the coils between the same direction and opposite directions.
Claims5
A suspension arm bushing provided in a vehicle, comprising:
- a housing which includes an inner cylindrical part having a hollow axial region and made of a magnetic material, and an outer cylindrical part arranged coaxially with the inner cylindrical part on a radially outer side of the inner cylindrical part and made of a magnetic material;
- a magnetic viscoelastic elastomer arranged in the housing;
- and
- coils arranged in the housing and applying magnetic fields to change viscoelasticity of the magnetic viscoelastic elastomer, wherein
- the coils include at least two coils,
- the magnetic viscoelastic elastomer includes first magnetic viscoelastic elastomers arranged at both ends in an axial direction of the housing, respectively, so as to entirely sandwich the coils, and
- a controller is provided to selectively switch directions of the magnetic fields generated by the coils between a same direction and opposite directions through the first magnetic viscoelastic elastomers.
