Abstract
An elastomeric mount for automotive application is provided having a preassembled, sealed fluid composite with a first and a second fluid chamber connected by means of a restricted orifice. The fluid package is accepted into and supported by an upper and a lower compliance member which provide general damping of vibration and oscillation of an automotive component. Means are provided to regulate the flow of the fluid and/or the fluid flow characteristics between the first and the second chamber in response to a stimulus to selectively isolate and dampen undesired vibration.
Claims7
An elastomeric vehicle mount comprising a top resiliently deformable compliance member and a bottom resiliently deformable compliance member which when secured together have opposing internal surfaces that define an inner chamber, and an integral fluid tight damping chamber containing damping fluid to dampen resilient deformation of said mount, said damping chamber being adjacent at least one of said compliance members;
- said fluid tight damping chamber being sealed prior to assembly in position adjacent said at least one of said compliance members.
A fluid-damped resilient mounting device in which damping fluid occupies a damping chamber defined adjacent at least one resiliently deformable member of the device, to dampen resilient deformations thereof, characterized in that
- the damping fluid is contained in a fluid-tight module having a diaphragm wall, the fluid-tight module being sealed prior to assembly against the resiliently deformable members with the diaphragm wall thereof conforming against the resiliently deformable member.
