The bellow is disposed within the guide tube and the plurality of tabs are received within a corresponding one of the fixing openings.

An air suspension assembly comprises a top and a bottom disposed on a center axis and spaced apart from one another. A bellows of an elastomeric material extends between a first end secured to the top and a second end secured to the bottom defining a chamber. The chamber extends between the top, the bottom, and the bellows for containing pressurized air, whereby a pressure of the pressurized air is controlled based on a force applied. The bellows has an interior surface and an exterior surface and including a plurality of convolutes extending between the first end and the second end. Each convolute of the plurality of convolutes includes a pair of outer lobes and an inner lobe with each outer lobe of the pair of outer lobes having an outer lobe thickness extending between the interior surface and the exterior surface of the bellows.

A communication and power transmission module includes a communication connection portion adapted for communicative coupling with an associated controller. A wireless power and communication portion is adapted for communicative coupling with an associated sensing device operatively associated with an associated suspension component and/or an associated wheel. The wireless power and communication portion is operable to communicate wireless data and/or signals to and/or from the associated sensing device and operable to wirelessly transmit power to the associated sensing device. Gas spring assemblies and vehicles including one or more of such communication and power transmission modules are also included.

A user accessible shock travel spacer assembly is disclosed herein. The system is used on a shock assembly having a shaft with an initial predefined stroke length. A retaining cap having a retaining cap thickness and a retaining cap opening therethrough. The retaining cap opening having a diameter that is larger than an outer diameter (OD) of a shaft of a shock assembly. At least one fastener to fasten the retaining cap with a portion of the shock assembly about the shaft, such that the retaining cap reduces a stroke length of the shaft of the shock assembly by the retaining cap thickness.

A multi-dimensional magnetic negative-stiffness mechanism and a multi-dimensional magnetic negative-stiffness vibration isolation system composed thereof are provided. The multi-dimensional damping system is composed of a positive-stiffness mechanism, a multi-dimensional negative-stiffness mechanism, a floating frame, a vibration isolated body, and a mounting base. The positive-stiffness mechanism is a traditional elastic element connected to the vibration isolated body and the mounting base, and provides supporting forces in an X direction, a Y direction, and a Z direction, and a basic vibration isolation function. The multi-dimensional negative-stiffness mechanism is composed of at least two negative-stiffness magnetic groups. Each negative-stiffness magnetic group may provide one-dimensional or two-dimensional negative stiffness. Through a series connection of the at least two negative-stiffness magnetic groups, a two-dimensional or three-dimensional negative-stiffness effect may be implemented to improve the vibration isolation performance of the system in multiple dimensions.

A vibration attenuating fluid mount with a partitioned compensator includes an inner member, an outer member, a flexible member having a castellated transition between a fluid passageway and at least one operating chamber. A membrane may be disposed in a volume compensator in fluid communication with one or more operating chambers. The inner member and outer member may be connected via a castellated connection, a swaged lock ring, or a split-lock ring.

A gas spring consisting of a gas cylinder (2), a piston rod (3) which is movable in the axial direction in the gas cylinder (2), a guide (4), wherein an axially outwardly open gap (6) exists between the guide (4) and the gas cylinder. A protection (10) is arranged so that it extends radially over the width of the gap (6). The protection (10) is fixed in the guide (4) or in the cylinder wall (5). The protection is configured so that, when an axial force (F) is applied to the protection, a first part of the force (F) is transmitted to the guide (4) and a second part of the force to the cylinder wall (5), and thus the protection (10) relieves the load on the guide (4).
