A load sensor having a centrally disposed aperture element through which a fastening element of a vehicle air suspension assembly passes to affix the load sensor between the vehicle air suspension assembly and the vehicle suspension, wherein the load sensor has a force measurement sensor disposed proximate an elongate slot to generate a load signal which varies based on an amount of strain in the load sensor, wherein the load signal received by a load calculator allows calculation of the load exerted from the vehicle frame to the vehicle suspension.

A suspension arrangement for a vehicle includes a piston for supporting a flexible bellows assembly of the suspension arrangement, said piston having a first portion connectable to the flexible bellows assembly and a second portion connectable to a wheel axle, said piston further having an outer side and an inner side, and wherein said suspension arrangement further comprises a mounting structure for positioning an insertable sensor device toward the flexible bellows assembly, said mounting structure extending at least from the outer side to the inner side and having an outer opening for receiving the insertable sensor device from an outside of the piston.

An air spring strut assembly includes a top cap with a metal flange overmolded within a plastic overmold housing. The metal flange carries structural loads through the top cap and the plastic overmold housing includes non-load bearing complex shapes ands surfaces. A shock absorber and bellows are attached to the top cap to complete the air spring strut assembly.

An air-suspension module for a rigid axle including an air-bellows mount and an air-bellows module supported on the air-bellows mount in the operational state of the air-suspension module, the air-bellows module having an air-suspension bellows designed to change its shape and a supporting body connected to the air-suspension bellows, one of the components of the air-bellows mount and the supporting body having a coupling projection protruding along a virtual projection path, which engages with a coupling recess formed at the respectively other component along the projection path, a translatory relative movement of the supporting body being physically limited relative to the air-bellows mount, orthogonally with respect to the projection path and in a direction along the projection path; one of the components of the air-bellows mount and the supporting body having a latching body and the respectively other component of the air-bellows mount and the supporting body having a latching recess such that the latching body is in a form-locking latching engagement with the latching recess, so that a translatory relative movement of the supporting body relative to the air-bellows mount is physically limited in the two opposite directions along the projection path.

Gas spring end members include an end member wall with a longitudinal axis. End member wall includes an end wall portion and an outer wall portion. Outer wall portion extends peripherally about axis and is dimensioned to receivingly engage a flexible spring member. Rib wall portions are spaced around axis with each of rib wall portions projecting axially from end wall portion toward a rib end surface portion. Rib wall portions also include a rib edge surface portion spaced inward from an inner side surface portion of outer peripheral wall portion such that a gap is formed therebetween. Gas spring assemblies including one or more of such end members, and suspension systems including one or more of such gas spring assemblies are also included.

An end member assembly is dimensioned for securement to an associated flexible spring member. End member assembly includes first, second and third end member sections. First end member section includes a first outer peripheral wall portion. Second end member section includes a second outer peripheral wall portion. Second end member section is positioned in abutting engagement with the first end member section such that a groove extends peripherally around first and second end member sections between first and second outer peripheral wall portions. Third end member section is injection molded in situ with first and second end member sections such that third end member section extends peripherally around first and second end member sections within groove. Gas spring assemblies and vehicle suspension systems are also included.

A spring guide includes: a main body portion of which a coil spring is placed on a vehicle side, the main body portion being formed of a resin material; and a covering portion that covers an anti-spring side of the main body portion opposite to the coil spring. The covering portion is formed of a material having a physical property different from that of the resin material forming the main body portion.

A damping air spring for heavy-duty vehicle axle/suspension systems. The damping air spring includes a first chamber and a second chamber and at least one opening between the first chamber and second chamber to provide restricted fluid communication between the first chamber and the second chamber. An adsorptive material is disposed within the first chamber or the second chamber and works in conjunction with the at least one opening to provide damping characteristics to the air spring over a first and second critical range of frequencies.

Mounting assembly dimensioned for securement between a vehicle structure and a gas spring and damper assembly include a first end plate securable to the vehicle structure. A second end plate is attached in substantially fixed relation to the first end plate such that a mounting cavity is disposed therebetween. A connector housing is disposed within the mounting cavity and operatively connectable to the gas spring and damper assembly. A first bearing assembly is disposed between the connector housing and the first end plate and permits rotation of the connector housing relative to the first end plate while transferring forces acting longitudinally therebetween. A second bearing assembly is disposed between the connector housing and the second end plate and permits rotation of the connector housing relative to the second end plate while transferring forces acting longitudinally therebetween. Gas spring and damper assemblies are also included.

An end member assembly can include a first end member section and a second end member section that together form an end member volume. A partition section is provided separately and is disposed within the end member volume to separate the end member volume into at least two volume portions. At least one passage extends through the partition section and at least one control device is disposed in fluid communication along the passage. The control device substantially fluidically isolates the two volume portions under conditions of use below a predetermined differential pressure threshold. The control device permits fluid communication between the two volume portions under conditions of use in which the predetermined pressure threshold is exceeded. Gas spring assemblies including such an end member assembly as well as suspension systems and methods of manufacture are also included.
