1. A system comprising:
- a roadarm having a first end, a second end, and an opening near the first end;
a collar that fits within the opening, the collar being attachable to, or an integral part of, a vehicle hull; and
a bearing positioned around the collar and inside the opening;
a passive spring attached to the second end of the roadarm and positioned outside of the roadarm;
where the opening is configured for interchangeable use with any of;
(a) a passive suspension system damping element, (b) a semi-active suspension system damping element, and (c) an active suspension system actuator.

Abstract
In some embodiments, the present systems include, consist of, or consist essentially of a roadarm having a first end, a second end, and an opening near the first end; where the second end is configured for attachment to a passive spring (e.g., an air spring, a coil spring, a compressible fluid spring, or a leaf spring), and the opening is configured for interchangeable use with any of: (a) a passive suspension system damping element, (b) a semi-active suspension system damping element, and (c) an active suspension system actuator. Other systems are included, such as those with common control systems for the active and semi-active suspension systems. Methods relating to such systems.

8. A system comprising:
-
a roadarm having an opening; a collar that fits within the opening; a bearing positioned around the collar and inside the opening; a passive spring attached to and positioned outside of the roadarm; and one of a semi-active suspension system damping element and an active suspension system actuator surrounded, at least in part, by the collar; the opening and collar being configured such that, without modifying either of them, the system will operate at different times with the other of the semi-active suspension system damping element and the active suspension system actuator. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
creating a female common space envelope in an end of a roadarm that is configured to be attached to a vehicle hull, the roadarm having a spindle and a trailing end that is positioned closer to the spindle than to the end of the roadarm that is configured to be attached to a vehicle hull; placing a collar within the female common space envelope; and placing a bearing around the collar and within the female common space envelope, the female common space envelope being configured such that any of the following will fit at least partially within the collar at different times and can be used during operation of the vehicle;
a passive suspension system, a semi-active suspension system, and an active suspension system. - View Dependent Claims (16, 17, 18)
