Abstract

A shock absorber mounting device joins a shock absorber provided between an axle and a vehicle body to the vehicle body. The shock absorber mounting device includes a magnetic rubber mount having magnetic particles thereinside and being provided between the shock absorber and the vehicle body, an electromagnetic coil configured to apply a magnetic field to the magnetic particles, and a controller configured to supply an excitation current to the electromagnetic coil.

First claim

1 . A shock absorber mounting device that joins a shock absorber provided between an axle and a vehicle body to the vehicle body, the shock absorber mounting device comprising:
a magnetic rubber mount having magnetic particles thereinside and being provided between the shock absorber and the vehicle body; an electromagnetic coil configured to apply a magnetic field to the magnetic particles; and a controller configured to supply an excitation current to the electromagnetic coil.

2 . The shock absorber mounting device according to claim 1 , further comprising:
a vehicle body side joining member that joins the magnetic rubber mount to the vehicle body; a shock absorber side joining member that joins the magnetic rubber mount to the shock absorber; and a yoke member that directs the magnetic field produced by the electromagnetic coil between the vehicle body side joining member and the shock absorber side joining member, wherein the magnetic rubber mount is arranged on an inner side of the electromagnetic coil, and the vehicle body side joining member, the shock absorber side joining member, and the yoke member cover the electromagnetic coil.

3 . The shock absorber mounting device according to claim 2 , wherein
the shock absorber is an extendable and retractable cylindrical shock absorber, and the magnetic field produced by the electromagnetic coil acts on the magnetic rubber mount along a direction of extension and retraction of the shock absorber.

4 . The shock absorber mounting device according to claim 1 , wherein
the controller performs control to reduce the excitation current supplied to the electromagnetic coil as an up-down acceleration of the shock absorber increases.

5 . The shock absorber mounting device according to claim 1 , wherein
the controller performs control to increase the excitation current supplied to the electromagnetic coil as a running speed of the vehicle body increases.
