| 20150091228 | SPRING-DAMPER SYSTEM FOR USE IN BEARINGS OR AS A DAMPER - A spring-damper system for use in bearings or as a damper, in particular as a spring-damper system in active engine bearings includes a coupling device which can be coupled to a load and to a supporting device at a bearing or damping point, in order to mount the load in such a way that it can vibrate on the supporting device. The coupling device is designed to transmit a load input generated by the load substantially without loss to a spring-damper device and to absorb a reaction thereto by the spring-damper device and to feed said reaction back to the load, in order to counteract the load input in a vibration-damping fashion. In this context, the spring-damper device can be arranged and/or is arranged spatially separate from the bearing or damping point. | 04-02-2015 |
| 20150377317 | MULTI-STATE ELECTRONICALLY SWITCHABLE ENGINE MOUNT ASSEMBLY - An engine mount assembly includes a housing, an inertia track received in the housing and an elongated fluid damped first path that is adapted to communicate with an associated first fluid chamber on a first side and an associated second fluid chamber on a second side. A non-damped second path is adapted to communicate with the associated first and second fluid chambers. A decoupler is received in the housing, an idle diaphragm in the housing that selectively controls communication between the first and second fluid chambers to selectively alter the damping. First and second ports in the housing communicate with the decoupler and the idle diaphragm, respectively. A first solenoid selectively controls fluid flow through the first port and a second solenoid selectively controls fluid flow through the second port. | 12-31-2015 |
| 20160091047 | VIBRATION ISOLATION SYSTEM - Apparatus and methods to reduce unwanted motion in a payload of a precision instrument are described. The payload may be supported by an intermediate mass. A feedback signal based upon sensed motion of the intermediate mass may be applied to an intermediate-mass actuator arranged to drive the intermediate mass. Additionally, a feedforward signal may be applied to a payload actuator arranged to drive the payload and used to suppress unwanted motion of the payload. The feedforward signal may be derived from a source within the apparatus or external to the apparatus that would otherwise cause unwanted motion of the payload. | 03-31-2016 |
| 20160097436 | VIBRATION ISOLATION SYSTEMS INCLUDING MULTI-PARAMETER ISOLATORS PROVIDING PIEZOELECTRIC-BASED DAMPING - Embodiments of a vibration isolation system are provided. In one embodiment, the vibration isolation system includes a first isolator having opposing mounting interfaces, a tuning spring disposed between the opposing mounting interfaces, and a piezoelectric actuator disposed between the opposing mounting interfaces and coupled in series with the tuning spring, as taken along a first load path through the first isolator. A controller is operably coupled to the piezoelectric actuator. During operation of the isolation system, the controller varies a control voltage supplied to the piezoelectric actuator to dampen vibrations transmitted through the first load path. | 04-07-2016 |
| 20160123426 | ELECTRONIC SEMI ACTIVE CONTROL ENGINE MOUNT HAVING VARIABLE AIR CHAMBER - An electronic semi active control engine mount having a variable air chamber includes a variable air chamber diaphragm that absorbs the exciting force of fluid due to an external force by elastically deforming. An air chamber supports the variable air chamber diaphragm with the atmospheric pressure. A fork is separated from the diaphragm to keep the air chamber into which air flows in idling of an engine, and comes in close contact with the variable air chamber diaphragm to remove the air chamber into which the air flows when a vehicle is driven. An actuator either separates the fork from the variable air chamber diaphragm or allows the fork to be in close contact with the variable air chamber diaphragm. | 05-05-2016 |
| 20160138671 | ACTIVE ENGINE MOUNT FOR VEHICLE - An active engine mount for a vehicle includes an upper body which has a main rubber and an upper liquid chamber, and a lower body which is coupled to a lower portion of the upper body. An orifice circular plate divides an interior of the upper and lower bodies into the upper liquid chamber and a lower liquid chamber inside the upper and lower bodies, and has an orifice through which a fluid flows between the upper and lower liquid chambers. A diaphragm is installed below the orifice circular plate inside the upper and lower bodies, and forms the lower liquid chamber. A semi-active mount is in contact with a central portion of the diaphragm by a plunger inside the lower body, and operates by an electromagnet. | 05-19-2016 |
