Abstract
Presented herein, inter alia, are suspension system components having tuned accumulator sizing and/or stiffness. Such suspension system components are envisioned for use in a distributed active suspension system of a vehicle. In particular, through appropriate sizing of accumulators of a suspension system component of a vehicle, ride quality of the vehicle may be improved and so called “rough ride” issues may be precluded. Alternatively or additionally, various valves or alternative compliant mechanisms may be included in the suspension system component, so that desirable performance may be obtained for a range of operating conditions.
Claims11
A nested accumulator assembly for a hydraulic system, the nested accumulator assembly comprising:
- a first accumulator including:
- a first accumulator housing that at least partially defines a first internal volume;
- and
- a first piston that divides the first internal volume into a first gas-charged chamber and a first hydraulic fluid chamber;
- and
- a second accumulator including:
- a second accumulator housing that at least partially defines a second internal volume;
- and
- a second piston that divides the second internal volume into a second gas-charged chamber and a second hydraulic fluid chamber;
- wherein at least a portion of the second accumulator is disposed within the first internal volume.
