Embodiment Construction

[0024] The present disclosure relates to active vibration isolation systems. Active vibration will be described in terms of providing isolation for equipment (which will contain a suspended platform on which the payload resides, but may contain other elements as well) from vibration input applied to the base to which the vibration isolation system is coupled isolate the system. An active vibration system applies a controlled force between the base and the suspended platform to provide vibration isolation for the suspended platform on which the payload resides. Many of the embodiments disclosed herein will discuss active vibration systems applied to vehicle seats. It should be understood, however, that the described vibration isolation system is not limited to application in vehicle seating. Any application where it is desirable to isolate a payload from some vibration input is contemplated herein.

[0025] The isolated equipment consists of the entire structure isolated fro...

Abstract

An active vibration isolation system for isolating a suspended platform from vibration input to the vibration isolation system base includes an exoskeleton which supports the suspended platform relative to the base. The exoskeleton includes first and second scissors mechanisms with main links of unequal length. The main links pass through a parallel condition as the suspended platform moves over its intended range of travel relative to the base. The vibration isolation system may include a rotary actuator and a drive mechanism separate from the exoskeleton for providing force output from the rotary actuator to the suspended platform. The rotary actuator may include inner and outer rotors which rotate relative to each other and may be free to rotate relative to the exoskeleton. The rotary actuator may be free to translate relative to the vibration isolation system base and the suspended platform.

Description

[0001] Cross References to Related Applications Background technique [0002] Vibration isolation systems attempt to isolate the payload from vibration disturbances. Vibration isolation systems can be passive, semi-active or fully active. A fully active vibration isolation system uses as part of the isolation system a source capable of applying a force of arbitrary magnitude and phase without any disturbance. Some applications for vibration isolation systems are ground vehicles, ships or aircraft. Vehicles such as passenger cars, long-haul trucks, construction equipment, or the like typically employ some type of suspension system as a vibration isolation system in order to separate the vehicle occupants from the vehicle along its path (where the path may be on and / or off) Vibration isolation induced by disturbances encountered while driving. In some vehicles, however, the vehicle suspension may not be sufficient to effectively isolate the vehicle occupants from road-induce...
