Abstract: A spring wall for securement between associated end members for forming an associated gas spring assembly includes a first wall portion that extends axially along a longitudinal axis and circumferentially thereabout. The first wall portion is formed from an unreinforced elastomeric material, and the first wall portion has a first nominal stiffness value. A second wall portion extends along the longitudinal axis and circumferentially thereabout. The second wall portion is disposed in longitudinal relation to the first wall portion and has a second nominal stiffness value that is different from the first nominal stiffness value of the first wall portion such that a non-constant stiffness profile is established along a longitudinal length of the spring wall. A gas spring and a gas spring and reservoir assembly utilizing such a spring wall as well as a method of manufacturing a gas spring are also included.

Abstract: A rigid jounce bumper includes a body and at least one support segment projecting axially from an end of the body. The rigid jounce bumper is formed from a substantially non-elastic material such that the rigid jounce bumper can support axially-applied loads without undergoing substantial axial deflection. The at least one support segment is capable of displacement relative to the body when under laterally-applied loads. A gas spring assembly having such a rigid jounce bumper is also included.

Abstract: A connector fitting and air spring assembly includes a connector fitting supported on an end member of an air spring. The connector fitting is secured on the air spring by a retaining member engaging the end member of the air spring.

Abstract: A fluid suspension member having a flexible wall at least partially defining a fluid chamber and having a passage formed therethrough. A connector fitting is received within the passage, and a groove extends into the flexible wall adjacent the passage. A method is also disclosed.

Abstract: A protective curtain assembly for an associated fluid suspension system of an associated vehicle includes a section of curtain material and a first securement device securing the second of material along at least a portion of the associated suspension system. A suspension system including a protective curtain is also described.

Abstract: A modular piston assembly is associated with an air spring assembly that has a bellows rolling over a surface of the piston assembly. The modular piston assembly includes a first piston portion adapted to fasten to an associated air spring bellows. A second piston portion separate from the first portion, is adapted to fasten to an associated mounting component. Interlocking members are provided to secure the first and second piston portions together, and/or any desired intermediate piston portions. Discrete air reservoirs may also be included in the modular piston assembly to increase the volume of the air spring.

The at least one support segment is capable of displacement relative to the body when under laterally-applied loads. A gas spring assembly having such a rigid jounce bumper is also included.

Abstract: A jounce bumper assembly includes a jounce bumper and a bumper retainer. The jounce bumper includes opposing end walls and a side wall extending therebetween. The bumper retainer includes a side wall for engaging the side wall of the jounce bumper and thereby restricting radially outward deflection of the jounce bumper. A gas spring assembly and a vehicle suspension system including a jounce bumper assembly are included. A method of utilizing a jounce bumper assembly is also included.

Abstract: A reflector includes a first end surface, an opposing second end surface and a plurality of reflector surfaces. A first reflector surface extends from adjacent the first end surface toward the second end surface. A second reflector surface extends from adjacent the first reflector surface toward the second end surface. One or more of the plurality of reflector surfaces can include a plurality of facets or reflector zones. A gas spring assembly and suspension system using the reflector is also disclosed.

Abstract: A vehicle air spring assembly having a pair of spaced end members which sealingly engage a flexible bladder to form an internal air chamber having an internal volume. One of the end members is a bead plate which has an annular outer end portion which is crimped to the bladder to provide an air tight seal therebetween. The end plate has a recessed portion located between the outer end portion which projects into the air chamber to reduce the volume of the air chamber to change the spring characteristic of the air spring. A plurality of reinforcing gussets extend between the recessed portion of the bead plate and a surrounding upstanding wall which extends between the outer end portion and recessed portion to enable the bead plate to be clamped by fasteners against an adjacent vehicle component and resist deformation when subjected to internal pressure.

Abstract: A vehicle air spring assembly has a pair of spaced end plates which sealing engage a bladder to form an air chamber. A pair of bead skirts are attached to the end plates to guide the bladder radially outwardly as the air spring is compressed. By guiding the bladder as it expands radially outwardly, the bead skirts control the effective area with respect to the air spring height, thus controlling the dynamic load and dynamic spring rate of the air spring. The bead skirts are formed complementary in shape and nestle together as they move towards one another. This nestling reduces pinching of the bladder when the air spring is compressed during use.
