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.

An adapter piece may be employed to connect a damper tube and an air spring piston in a non-positive manner. The adapter piece may comprise a spring region. The adapter piece may also include a first ring region and a second ring region, and the spring region may be positioned between the first ring region and the second ring region. Further, an air spring damper system may utilize the spring region of such an adapter piece to connect a damper tube and an air spring piston in a non-positive connection. The damper tube may include a bulge with a supporting element positioned on the bulge. The adapter piece may lie on the supporting element.

A suspension component for a vehicle may include a spring section performing a support function for supporting a portion of the vehicle and a shock absorbing section performing a damping function to damp action of the spring section. The spring section may be adjustable to provide adjustable support characteristics and the shock absorbing section is adjustable to provide adjustable damping characteristics. The spring section may be adjustable independent of the shock absorbing section. The spring section of the suspension component may define a gas chamber for holding a quantity of a gas to provide a spring support for the vehicle, and the shock absorbing section of the suspension component may define a fluid chamber to provide damping of movement of the spring section.

A spring assembly for a vehicle is provided. The spring assembly may include a piston, and a sleeve with a noncircular cross section, the sleeve made from an unreinforced synthetic elastomeric material and being free of reinforcing fibers. The sleeve is coupled with a plurality of end components and defines a deformable pressure vessel, the deformable pressure vessel supplies a support force, and at least one of the end components is the piston.

An air spring for a cab of a heavy truck with automatic height adjustment, in which the air spring is provided between the cab and a frame of a truck and supports the cab with a pressure of air filling in the air spring, includes a canister in which an internal space is formed, and a piston movably mounted in the internal space of the canister and configured to ascend and descend relative to the canister. A port opening unit is provided adjacent to an intake port and an exhaust port of the piston, respectively. When the cab ascends or descends, each of the port opening units comes into contact with guides, each having an inclined surface, formed in the canister to open either the intake port or the exhaust port.

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.

Disclosed are a shock absorber and an automobile. The shock absorber includes a shock absorber cylinder and an air spring arranged around the shock absorber cylinder. The air spring includes a damping spring and a piston. A free end of the damping spring is supported at a free end of the piston. A support is disposed between the piston and the shock absorber cylinder. The free end of the piston is supported on the shock absorber cylinder by the support. In the shock absorber according to the invention, the piston and the shock absorber cylinder can be connected in a simple way.

A spring-damper assembly includes a damper and an adjustable gas spring system coupled to the damper. The spring-damper assembly can be coupled to a vehicle as part of a suspension thereof. The adjustable gas spring system maintains the ride height of the vehicle while absorbing forces from changes in the terrain. The dampers control unwanted movement of the coil spring and dissipate forces from the suspension.

End members are supportable along a damper housing and dimensioned for securement to a flexible spring member. The end members include a wall with a first wall portion having an outer surface portion dimensioned to receivingly engage the flexible spring member. A second wall portion includes an inner surface portion dimensioned to receivingly engage a torsional isolator supported on the damper housing. A third wall portion extends radially outward beyond the second wall portion and includes a passage surface at least partially defining a passage extending axially through the third wall portion. The passage is dimensioned to receive a projection of the torsional isolator. End member assemblies including such an end member as well as gas spring and damper assemblies and suspension systems are also included.
