A method for forming and installing a retaining ring comprises: feeding a wire in a linear path into a forming die having a circular bore; forming, using the forming die, the wire into a formed ring having a ring shape; transferring the formed ring from the forming die to a transfer puck; and installing the formed ring, as a retaining ring, in a tube of a product assembly. The formed ring is maintained in a constrained state between forming in the forming die and installation in the product assembly. A system for forming and installing a retaining ring into a product assembly includes a forming die configured to form a wire into a formed ring having a ring shape; and a transfer puck to transfer the formed ring from the forming die. The formed ring is maintained in a constrained state from forming through installation.

A bracket comprises a body extending along a center axis between a first end and a second end. The body defines a first groove and a second groove. The first groove, located at the first end and flaring radially outwardly, presents a first slanted surface. The second groove, located at the second end and flaring radially outwardly, presents a second slanted surface. A pair of coupling members including a first and a second coupling member are respectively located in the first and second grooves for engagement with a housing of a hydraulic damper assembly. The first end includes at least one first deformation for retaining the first coupling member. The second end includes at least one second deformation for retaining the second coupling member. A hydraulic damper assembly including the bracket and a method of joining the bracket and the hydraulic damper assembly are also disclosed herein.

A control system for an active powertrain mount includes a control signal which is based on the input velocity of the chassis at the active powertrain mount. The control signal may be proportional to the input velocity or to the mount velocity, which is the difference between the input velocity of the chassis at the active powertrain mount and the output velocity of the powertrain component at the active powertrain mount. The input velocity of the chassis at the active powertrain mount may be determined by a controller based on the CG heave and the roll and pitch velocities of the chassis. The output velocity of the powertrain component at the active powertrain mount is determined by the controller by integrating an acceleration signal from a component accelerometer disposed on the powertrain component proximate to the active powertrain mount. Corresponding methods for controlling an active powertrain mount are also provided.

A tie bar assembly includes front and rear units each including inner inserts interconnected with outer inserts with webs of elastomeric material. A pole sub-assembly is disposed between the units. The pole sub-assembly and the units define front and rear fluid chambers containing a magneto-rheological fluid. Fluid orifices are disposed through the pole sub-assembly for flow of the magneto-rheological fluid between fluid chambers. An electromagnet coil generates an electromagnetic field to affect viscosity of the magneto-rheological fluid. A connecting rod connects inner inserts and is slidably disposed through the pole sub-assembly for causing movement of the magneto-rheological fluid between fluid chambers. A displacement sensor detects movement to generate a signal to the electromagnet coil. Front and rear travel cushions are each disposed on the inner inserts for limiting the movement of the inner inserts toward the pole sub-assembly.
