A monotube shock absorber assembly includes a housing (), a gas cup () slidably disposed in the interior () of the housing (), and a piston () slidably disposed in the interior () of the housing () to define an oil compression chamber () between the piston () and the gas cup (). A cushion () engages one of the piston () and the gas cup () and extends axially into the oil compression chamber () for intermittent contact with the other of the piston () and the gas cup (). The cushion () is a resilient material and deforms in response to the cushion () contacting the other of the piston () and the gas cup (). In a preferred embodiment, the cushion () defines a central opening () for decreasing the axial stiffness of the cushion () and engages the gas cup () for intermittent contact with the piston (). In a preferred embodiment the cushion () presents an anchor () for retaining the cushion () against the piston () for intermittent contact with the gas cup ().

Fluid damper with internal compression spring

A powertrain mount comprises an upper orifice plate, a lower orifice plate, and a generally planar diaphragm having an enlarged central node. The central node is in constant contact with the upper orifice plate and in contact with the lower orifice plate. A periphery of the diaphragm is free to move between the upper orifice plate and the lower orifice plate.

Hydraulic engine mount with center-clamped decoupler

A hydraulic mount provides passive rate dip performance through use of a secondary orifice track-mass resiliently constrained within a first orifice track for reciprocating movement within the first orifice track under conditions such as engine idle, and constrained against reciprocating motion within the first orifice track for conditions imposing large amplitude, low frequency loads on the mount.

Hydraulic mount with reciprocating secondary orifice track-mass

A mount for a powertrain component of a motor vehicle comprises first and second mounting members, an elastomeric body connected to the first mounting member and connected to the second mounting member, and a plate. The plate defines first and second chambers, and has an orifice for the passage of fluid therethrough. A plunger having at least one hole is connected to the first mounting member, and a compliance member is disposed proximate the at least one hole.

Powertrain mount with high frequency plunger

A hydraulic engine mount includes opposed mounting members secured to an elastomeric body and a base, respectively, with an orifice plate assembly interposed the body and the base to define a pumping chamber and a reservoir for hydraulic fluid to flow therebetween through an orifice track formed by the orifice plate assembly. An elastomeric decoupler disk is secured in a recess formed between two orifice plates of the orifice plate assembly and defines a gas spring or cushion space which may be filled or vented by a removable plug in one of the orifice plates. Improved dynamic rate and damping at low amplitude inputs to the mount are provided by the gas cushion biased decoupler as compared with a decoupler type mount without the gas cushion bias. The mount provides an advantage over conventional decoupled hydraulic mounts in that very strict dimensional tolerances are relaxed and performance characteristics, as well as ease of manufacturing, are improved.
