A gas cup for a damper assembly comprises a body including an upper surface, a lower surface, an exterior surface and an interior surface. The body defines an aperture extending through the upper surface and the lower surface. A decoupler is located in the aperture and secured to the body. A bridging member is located between the decoupler and the body and coupled to the decoupler and the body. The decoupler and the bridging member is made from materials having different elasticity to allow the decoupler to move in the aperture in response to a volumetric change in the damper assembly and to provide variable tuning of the damper assembly. A damper assembly including the gas cup is also disclosed herein.

A hydraulic mount apparatus includes a housing having an upper portion and a lower portion disposed on a center axis and defining a housing chamber. A partition member is disposed in the housing chamber dividing the housing chamber into a pumping chamber and a receiving chamber. The pumping chamber extends between the upper portion and the partition member. The receiving chamber extends between the lower portion and the partition member. A decoupler is attached to the partition member separating the pumping chamber and the receiving chamber. A moving member is disposed in the pumping chamber and attached to the decoupler. The moving member is made from a non-elastomeric polymer sheet secured to the decoupler for providing the additional damping force.

A fluid damper assembly for use in a vehicle includes a piston subassembly which includes a plurality of inflow passages and at least one rebound disk for restricting flow of hydraulic fluid through the inflow passages. A rod extends through the piston subassembly to actuate the piston subassembly between a rebound stroke and a compression stroke. An actuator supported by and within the rod includes a piezoelectric device and an amplifier for adjusting the damping force during the rebound stroke, thereby adjusting the suspension of the vehicle. A shaft within the rod is connected to a retainer to transmit motion from the amplifier to compress a spring and disengage the retainer from the rebound disk to allow the rebound disk to flex solely in response to hydraulic fluid pressure from the rebound stroke to open the inflow passages and reduce the damping force during the rebound stroke.

Actuation mechanism for controllable damper

A top mount assembly including a housing for being connected to the frame of the vehicle. A rod connection assembly is disposed in the housing for being attached to a piston rod of the damper assembly. A chamber is defined between the rod connection assembly and the housing for receiving a fluid. A resilient member is disposed between the rod connection assembly and the housing. A partition assembly is positioned between the resilient member and the housing and axially divides the chamber into an upper chamber region and a lower chamber region. The partition assembly defines at least one passage that extends between the upper chamber region and the lower chamber region. At least one electromagnetic coil is disposed adjacent to the passage for selectively modifying the characteristics of the fluid passing through the passage to modify the damping characteristics of the top mount assembly.
