Abstract: A damper includes a damper tube (a pressure tube or a reserve tube for a mono-tube or a double tube damper respectively) including a first end and a second end opposite to the first end. The damper includes a base member. The base member includes a cup portion at least partially enclosing the first end of the damper tube, and a sleeve portion extending from and integral with the cup portion. The sleeve portion surrounds a length of the damper tube. The sleeve portion is attached to the damper tube. Further, the damper includes a knuckle engaged with the sleeve portion such that the sleeve portion is disposed between the knuckle and the damper tube.

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 suspension system including four dampers is disclosed where each damper includes a compression chamber and a rebound chamber. First and second hydraulic circuits interconnect the compression and rebound chambers of the front left and back right dampers, while third and fourth hydraulic circuits interconnect the compression and rebound chambers of the front right and back left dampers. A first bi-directional pump is connected between the first and second hydraulic circuits and a second bi-directional pump is connected between the third and fourth hydraulic circuits. The first and second bi-directional pumps can either pump in the same direction or in opposite directions. The level of pitch and roll stiffness can be adjusted by running the first and second bi-directional pumps to change the pressure in select hydraulic circuits of the system.

Abstract: A method of assembling an accumulator for a suspension damper where the method includes the steps of forming an outer shell of an accumulator, assembling a bellows assembly by connecting distal and proximal plates to opposite ends of an annular bellows wall, and inserting the bellows assembly into the outer shell. The outer shell is formed such that it includes a distal end with an end wall and an open end opposite the distal end. The bellows assembly is inserted into the open end of the outer shell with the distal plate facing the end wall of the outer shell. The method proceeds with coupling the distal plate of the bellows assembly to a stem of a gas charging port on the end wall of the outer shell at a fixed axial position using a fixation component that engages the stem of the gas charging port.

Abstract: A suspension system including four dampers each having a compression chamber and a rebound chamber. First and second hydraulic circuits interconnect the compression and rebound chambers of the front dampers, while third and fourth hydraulic circuits interconnect the compression and rebound chambers of the back dampers. A first longitudinal hydraulic line extends between and connects the first and third hydraulic circuits and a second longitudinal hydraulic line extends between and connects the second and fourth hydraulic circuits. A first bi-directional pump is connected in-line with a fluid distribution line that extends between and connects the first and second longitudinal hydraulic lines a can pump fluid in opposite directions through the fluid distribution line to provide active roll stiffness.

Abstract: A suspension system including hydraulic circuits that extend between dampers located at opposite corners of the vehicle and at least one load distribution unit that is connected in fluid communication with at least two hydraulic circuits. The load distribution unit includes a manifold block with a cylinder bore, a pair of pressure tubes, a piston rod assembly, and a pair of reserve tubes. The pressure tubes are partially received in the cylinder bore to define a pair of opposed cylinders. The piston rod assembly includes a piston rod and a pair of opposed pistons that are slidingly received within the opposed cylinders. The reserve tubes are at least partially received in the cylinder bore and are arranged annularly about the pressure tubes to define a first pair of reservoir chambers between the pressure tubes and the reserve tubes.

A first hydraulic circuit includes a first hydraulic line fluidly connecting the first rebound chamber of the first damper and the second compression chamber of the second damper. A second hydraulic circuit includes a second hydraulic line fluidly connecting the first compression chamber of the first damper and the second rebound chamber of the second damper. A proportional pressure accumulator in fluid communication with at least one of the first and second hydraulic circuits includes an accumulation chamber, a pressurized gas chamber and a volume varying mechanism.

Abstract: A single axle suspension system that includes right and left dampers, first and second hydraulic circuits, a first pressurizing mechanism that is connected in fluid communication with the first hydraulic circuit, and a second pressurizing mechanism that is connected in fluid communication with the second hydraulic circuit. The first and second pressurizing mechanisms are configured to provide active roll control by adding and removing hydraulic fluid to and from the first and second hydraulic circuits to increase and decrease pressure inside the first and second hydraulic circuits independent of damper movements. This in turn causes a simultaneous increase in the fluid pressure inside either the first working chamber of the right and the second working chamber of the left damper or 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.
