Abstract: A continuously variable damper is disclosed. The damper includes an elongate outer tube and inner tube with a piston in the inner tube. The piston defines a rebound working chamber and compression working chamber. An active rebound valve is in fluid communication with the rebound working chamber through a rebound down tube, and an active compression valve is in fluid communication with the compression working chamber through a compression down tube. An intake compression valve is in fluid communication with the rebound working chamber through the rebound down tube, and an intake rebound valve is in fluid communication with the compression working chamber through the compression down tube. The opposite position of the intake valves balance the active rebound and compression valves to avoid asymmetric/bending loads on the inner tube in the damper.

Abstract: A steering damper assembly includes a cylindrical pressure tube defining a working chamber; a piston assembly disposed in the working chamber; a reserve tube extending circumferentially around the pressure tube and defining a reservoir chamber that is radially between the reserve tube and the pressure tube; a base valve fluidly connecting the working chamber and the reservoir chamber; and a piston rod fixed to the piston assembly. The reserve tube includes a cylindrical portion and a bulged portion. The cylindrical portion extends concentrically around the pressure tube. The bulged portion includes a first circumferential section and a second circumferential section, the first circumferential section having a maximum radial distance at most equal to an inner radius of the cylindrical portion, and the second circumferential section having a maximum radial distance greater than the inner radius of the cylindrical portion.

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.
