Suspension strut

摘要

The strut includes a reciprocative load bearing assembly and one, two or more sets of springs, either elastomeric or coil type, which operate either singularly, in parallel or in series to provide a variable rate spring force. A frictional or "coulomb" damper is operated by one or more of the spring sets to provide a variable rate damping force. The strut provides a substantially constant ride frequency over a wide range of load conditions and is especially adapted for rubber tired vehicle application.
