A hydraulic rebound stop assembly for a hydraulic damper is provided. The rebound stop assembly includes a movable rod, a retention feature fixed to the movable rod, and a ring circumscribing and slidingly engaging the movable rod. The ring axially extends between a first end surface and an axially spaced apart second end surface. The ring includes an outer wall and an inner wall defining a cavity. The retention feature is at least partially received in the cavity. The ring is axially movable between a first position and a second position. A dimension of the cavity is greater than a dimension of axial travel of the ring between the first position and the second position. In the first position, the retention feature constrains axial movement of the ring in a first direction.

A hydraulic fluid reservoir fluidly couple to a shock absorber. The hydraulic fluid reservoir having a flexible housing, a fluid channel, and a pump provided along the fluid channel. The flexible housing having a flexible wall defining a first interior, with the first interior a variable volume of hydraulic fluid and no air. The fluid channel fluidly coupling the first interior with the shock absorber. The pump being configured to move the flow of hydraulic fluid into or out of the flexible housing. The flexible housing being configured to move between a first position and a second position.

A hydraulic fluid tank assembly for use with a suspension system for a vehicle is provided. The hydraulic fluid tank assembly includes a tank having a chamber configured to contain a volume of hydraulic fluid and a volume of gas, and a breather cap assembly. The breather cap assembly includes a breather cap having a passageway and a recess, a filter having one or more openings configured to permit gas to pass therethrough, and a splash guard coupled to the breather cap, the splash guard retaining the filter in the recess of the breather cap, and the splash guard having a distal opening. The passageway of the breather cap, the openings of the filter, and the distal opening of the splash guard are fluidly connected and configured to permit gas to pass therethrough to and from the chamber of the tank and the atmosphere.

A suspension system and method of controlling the same is provided. The suspension system includes a damper and a pump assembly fluidly connected with the damper, the pump assembly having a pump and a pump motor. The method includes: (i) monitoring real-time data reflecting at least one of a dynamic state of the vehicle and an input from a vehicle operator; (ii) calculating a damper force based on the real-time data, the damper force being a force to be output by the damper; (iii) determining a hydraulic torque to be output by the pump based on the calculated damper force; (iv) determining a current to be applied to the pump motor based on the determined hydraulic torque; (v) applying the determined current to the pump motor to operate the pump; and (vi) applying a force to the vehicle by the damper.

An actively controlled valve assembly and a method for assembling an actively controlled valve assembly comprising a coil housing, a valve housing, an intermediate member and a resilient locking member which is to be pre-tensioned into a pre-tensioning aperture, where the intermediate member comprises a guiding projection for pre-tensioning the resilient locking member which assures that it is brought into the correct position when the assembly is in the final assembled position where the resilient locking member is locked in a locking aperture of the valve housing.

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.

A shock absorber for a vehicle including a pressure tube, a piston body slidably positioned within the pressure tube, a blowoff disc having a first surface in contact with a surface of the piston body and an opposite second surface, a disc stack, and a preload ring axially positioned between the disc stack and the blowoff disc. The preload ring is in direct contact with the second surface of the blowoff disc and includes a circular outer surface and a substantially constant thickness. The preload ring further includes a cross-sectional width that varies along its circumference. The preload ring increases smoothness of the blowoff opening behavior of the shock absorber, which can result in an improved comfort level of the vehicle.

A damper including a pressure tube, a reserve tube, an intermediate tube positioned between the pressure and reserve tubes, and one or more external control valves. A piston divides the pressure tube into first and second working chambers. A control valve seat provides a connection interface for the external control valve(s). The control valve seat includes a neck portion and a flange portion with a pair of cut-outs that are circumferentially spaced from one another to define first and second windows that are arranged in fluid communication with a reserve tube opening and first and second wings that extend out from the neck portion and sit/rest against the reserve tube.

A damper assembly includes a rod elongated along an axis. The damper assembly includes a body supported by the rod, the body having a first surface and a second surface opposite the first surface. The body and the rod define a passage between the body and the rod, the passage extending from the first surface of the body to the second surface of the body.

The present application relates to an interface element adapted for use in a shock absorber, the interface element comprising a cylindrical shape coaxially arranged around an axis A, wherein the interface element further comprises a first engaging end, a second engaging end, an engaging part, and at least one valve slot. The interface element forms a sealing interface between a first central cylinder, a second central cylinder, an inner cylinder and at least one valve in a shock absorber. The disclosure further relates to a shock absorber and a method for installing an interface element into a shock absorber.
