摘要： A vibration damping device is mounted between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. A cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with an outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. A fluid transfer duct is formed between the housing and piston and provides communication between fluid subchambers formed on opposite sides of the piston within the piston chamber. An electrode is attached to either the housing or piston for applying a voltage across the duct to affect the rheological response of an electrorheological (ER) fluid flowing therethrough to provide a controllable mechanism to modify the damping force characteristics of the device. Each end of the piston rod is slidably supported by a slide bushing assembly which is mounted within an end of the housing. The slide bushing assemblies are separated from the ER fluid contained in the fluid chamber by elastomeric seals to reduce bushing wear and deterioration of the ER fluid.

A blend of a high molecular weight high-cis polybutadiene and the low molecular weight high-cis polybutadiene is also disclosed for use in pneumatic tire treads. Desirably both the high and the low molecular weight polymers have high cis contents, with the low molecular weight polymer being at least 70 percent cis and the high molecular weight polymer being at least 92 percent cis. Desirably both polymers are made with a neodymium catalyst system. The blends provide a balance of properties including good snow traction, wet traction, and rolling resistance while providing a balance of good physical properties including tension at break, modulus etc.

摘要： A vibration damping system for absorbing shock loads includes a hydraulic damper containing a piston slidably reciprocating within an oil filled chamber and dividing the chamber into a pair of subchambers. A hydraulic motor is in fluid communication with and located between the subchambers and is controlled by a field responsive fluid, such as an electrorheological (ER) actuated device. The hydraulic motor transforms fluid motion into rotating motion by a pair of meshing gears. The ER device is a flow cell and is connected to a shaft of one or both of the meshing gears. The magnitude of an electric field applied to the ER fluid controls the flow rate of the hydraulic fluid passing through the hydraulic motor by controlling the resistive force to the rotary motion of the gears. A plurality of check valves controls the direction of flow of the hydraulic fluid between the hydraulic motor and the subchambers.
