Abstract: An end member assembly (EMI) with a longitudinal axis is securable to a flexible spring member (400). The end member assembly (EMI) has first and second ends. The end member assembly (EMI) includes first end member component (500) with a first component wall (502) includes an end wall portion (504) and a side wall portion (506). A second end member component (600) extends peripherally around and is permanently attached to the first end member component (500). The second end member component (600) includes a second component wall (602) with an outer surface portion (604). In some cases, the side wall portion (506) of the first component wall includes a plurality of first annular ribs (524) extending radially outward. The second component wall (602) includes a plurality of second annular ribs (612) extending radially inward. The pluralities of first and second annular ribs (524, 612) are axially interleaved with one another. Gas spring assemblies, gas spring and damper assemblies and methods of assembly are also included.

Abstract: The disclosure relates to a device for holding at least two valves within a component, such as, for example, an air spring, an air suspension strut, or an air suspension damper. In embodiments, a may device comprise at least two fixing bodies fixedly connected to each other for fixing the valves in valve seats of the component and at least two securing elements fixedly connected to the fixing bodies for securing the device in an assembly position on the component. Thus, the disclosure may provide an improved device for holding valves in which the number of parts may be reduced and/or which may be inexpensive.

Abstract: An air spring height sensor has a PCR (Pulsed-Coherent-Radar) sensor encased in a housing attached to an air spring. The housing also provides an integral channel for adding air to an air spring or releasing air. The PCR sensor is aligned with a connector to orient the sensor with respect to the air spring to accurately determine the height of the air spring.

Abstract: An air suspension strut for a motor vehicle comprises an air spring having an air spring cover and a rolling piston. A shock damper is integrated with the air spring and has a damper tube and a piston rod receivable within the damper tube. A rolling bellows is secured between the spring cover and the rolling piston thereby delimiting a variable volume pressure chamber filled with compressed air. The rolling bellows rolls on the rolling piston with a rolling fold being formed. A damper bearing is accommodated in a bearing socket of the air spring cover and connected to the piston rod. The damper bearing comprises a supporting piece, an elastomer body, and a sleeve. A closure element inserted in the bearing socket above the damper bearing. An elastic element arranged between the sleeve and the closure element.

Abstract: An air spring has an air-spring lobe made of elastomer material, which is clamped at the lobe ends thereof via connection parts between the sprung mass and the unsprung mass and is connected by way of the connection parts to the fastening parts of the sprung and the unsprung mass. The connection parts and the air-spring lobe enclose the working chamber that is under internal pressure and contains the air-spring volume. The working chamber is in connection with at least one air connection provided in the connection parts. At least one of the connection parts is connected to the associated fastening part by a releasable snap-in or latching connection and the snap-in or latching connection includes at least one air connection, to which a feed line or a hose for the compressed air supply is connected.

Abstract: Gas spring end members can include an end member body formed substantially entirely from a polymeric material. The end member body can have a longitudinal axis and can include a body wall with an end wall portion oriented transverse to the longitudinal axis. The end wall portion can at least partially define a mounting plane of the gas spring end member that is dimensioned to abuttingly engage an associated structural component. The body wall can also include an outer peripheral wall portion disposed radially outward of the end wall portion and that at least partially defines an outer peripheral edge of the gas spring end member. The outer peripheral wall portion can be axially offset from the end wall portion in a direction away from the mounting plane. Gas spring assemblies, suspension systems and methods are also included.

Abstract: An end closure (260) is dimensioned for securement to a gas spring end member (204). The end closure is dimensioned to form a substantially fluid-tight, friction-fit connection with a flexible spring member (206) that is in an at least substantially-cured condition. The end closure (260) can include an end wall portion (298), a first side wall portion (300) that extends from along the end wall portion (298) and a second side wall portion (304) that is disposed radially inward of the first side wall portion and is axially-offset relative to the end wall portion. The second side wall portion at least partially forms a mounting seat that is dimensioned to form a substantially fluid-tight, friction-fit connection between at least the second side wall portion of the end closure (260) and the flexible spring member (204). A gas spring assembly as well as a suspension system and methods of assembly are also included.
