Abstract

Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.

Claims (4)

1. A vehicle suspension damper comprising:

a hydraulic damping cylinder comprising an inner wall and an outer wall, said inner wall and said outer wall defining an annular space therebetween;

a cooling circuit having an attachment to an said hydraulic damping cylinder, wherein said attachment is configured to facilitate heat transfer between said cooling circuit and said hydraulic damping cylinder; and

a power conditioner coupled to said cooling circuit and a set of winding terminals that are attached to said hydraulic damping cylinder and a wire motor winding positioned in said annular space between said inner wall and said outer wall, wherein said power conditioner is configured to power said cooling circuit, and wherein conditioned power is conducted, via a set of conduits, from a set of output terminals of said power conditioner to a set of input terminals of said cooling circuit.
