Velocity transducer for vehicle suspension system

摘要

The transducer is directly associated with a fluid-type damper having a cover member and a cylinder member that undergo telescopic movement relative to each other in response to relative movement between vehicle components interconnected by the damper. In the preferred embodiments, both a passive electrical coil and a magnet are mounted upon the cover member, in fixed relationship to each other. Relative axial telescoping movement between the cover member and the cylinder member of the damper changes the flux field of the magnet and induces in the coil a voltage which is proportional to the relative velocity between the damper members and thus between the vehicle components interconnected by the damper. In an alternative embodiment, the magnet is mounted upon an end portion of the damper cylinder member.
