Abstract: A damper includes a pressure tube, a piston assembly, a piston rod, a reserve tube, and a reserve chamber. The damper also includes a base valve assembly having a valve body and a compression disc assembly. The compression disc assembly engages a first end face of the valve body to restrict flow through at least one compression passage. The base valve assembly also includes a rebound disc assembly. The rebound disc assembly engages a second end face of the valve body to restrict flow through at least one rebound passage. The rebound disc assembly includes at least one rebound bending disc that directly engages the second end face to close the at least one rebound passage. The rebound bending disc bends in response to pressure within the at least one rebound passage to permit flow through the at least one rebound passage.

Abstract: A frequency sensing system for a vehicle includes a shock absorber. The shock absorber has a frequency sensor configured to generate signals indicative of a shock frequency. The frequency sensing system includes a transmitter. The frequency sensing system includes an output device. The output device has a receiver for receiving the signals indicative of a shock frequency from the transmitter. One of the shock absorber and the output device is configured to compare the signals indicative of a shock frequency with a target frequency range. Further, the output device displays a notification when the shock frequency is outside of the target frequency range.

Abstract: A damper includes a piston coupled to a piston rod slidably positioned in a damper tube. A piston rod seal is positioned radially between the piston rod and a first end of the damper tube. A cap is positioned over the first end of the damper tube and includes a side wall positioned in contact with and extending annularly about the first end of the damper tube. An end wall extends radially inwardly from the side wall. A collector radially outwardly extends from the side wall. The cap includes a vent. The side wall includes an end face at an opposite end of the cap as the end wall. The collector is positioned axially between the vent and the end face of the side wall. The collector includes surfaces on which oil passing by the piston rod seal will accumulate.

Abstract: A single axle suspension system including right and left dampers, first and second hydraulic circuits, a first pressurizing mechanism connected in fluid communication with the first and second hydraulic circuits, and a second pressurizing mechanism connected in series with the first pressurizing mechanism. The first pressurizing mechanism is a gerotor pump that provides roll control by generating a pressure differential between the first and second hydraulic circuits, which increases fluid pressure inside either the first working chamber of the right damper and the second working chamber of the left damper or inside the first working chamber of the left damper and the second working chambers of the right damper to provide roll stiffness that counters vehicle roll during cornering. The second pressurizing mechanism adjusts static pressure within the first and second hydraulic circuits by adding and removing hydraulic fluid to and from the first and second hydraulic circuits.

Abstract: A single axle suspension system including right and left dampers, first and second hydraulic circuits, and a first pressurizing mechanism connected in fluid communication with the first and second hydraulic circuits. The first pressurizing mechanism includes a dual chamber ball/screw mechanism to adjust the volumetric capacity of a pair of first and second variable volume chambers that are arranged in fluid communication with the first and second hydraulic circuits. Thus, the first pressurizing mechanism provides roll control by generating a pressure differential between the first and second hydraulic circuits, which causes an increase in the fluid pressure inside either the first working chamber of the right damper and the second working chamber of the left damper or inside the first working chamber of the left damper and the second working chambers of the right damper to provide roll stiffness that counters vehicle roll during cornering.

Abstract: A damper including inner and outer tubes is provided. A piston is slidably disposed within the inner tube. An intermediate tube is positioned radially between the inner and outer tubes. An intermediate channel is disposed radially between the intermediate and inner tubes. A slanted elliptical seal is positioned at an oblique angle relative to a longitudinal axis of the inner tube and divides the intermediate channel into first and second intermediate channel portions. A first control valve is in fluid communication with the second intermediate channel portion via a first intermediate tube opening. A second control valve is in fluid communication with the first intermediate channel portion via a second intermediate tube opening.

Abstract: A valve arrangement for improved high frequency performance comprises: a valve seat member adapted in size and shape to define a valve seat and a flow-through opening; a valve member adapted to be displaceable relative the valve seat along a displacement axis during use in response to a damping fluid pressure force overcoming an opening force threshold, wherein the damping fluid pressure force is provided by damping fluid pressure acting on an inlet side of the valve member, the opening force threshold being at least partly adjustable by a force actuator, wherein the valve member and the valve seat member are adapted to provide a chamfer restriction provided with an opening cross-section which decreases from an inner lateral position to an outer lateral position relative the displacement axis. A shock absorber comprising the valve arrangement and a method for adjusting damping fluid flow are disclosed.
