A suspension system having a knuckle that rotatably supports a wheel end assembly. The knuckle may include a first platform that may have a toe link mount, a second platform that may have a stabilizer bar mount, a brake torque plate that may facilitate mounting of a brake subsystem, or combinations thereof.

End members are supportable along a damper housing and dimensioned for securement to flexible spring member. End members include a wall with a side wall portion including an inner side surface portion. First projections extend toward a first inner edge with a first shoulder surface portion faces a second end. Second projections extend inward beyond the inner side surface portion toward a second inner edge with a second shoulder surface portion facing a first end. Second projections are spaced axially from first projections such that a groove is formed inward of the inner side surface portion between first and second shoulder surface portions. End member assemblies including such an end member as well as gas spring and damper assemblies and suspension systems are also included.

An air spring for a motor vehicle or a driver's cab of a motor vehicle has a cover, a rolling piston and at least one air spring bellows. At least two damping devices are integrated into the air spring.

Air suspension strut for a motor vehicle comprising an air spring with a shock damper, wherein the air spring comprises an air spring cover and a rolling piston, wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston, the air spring cover comprises a damper bearing receptacle having a base and receiving a damper bearing of the shock damper, and the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached, wherein the air spring cover is manufactured from a plastic material and comprises a reinforcing core in order to increase the strength of the damper bearing receptacle, the reinforcing core being arranged in the base of the damper bearing receptacle and being at least partially surrounded by the plastic material of the air spring cover.

A suspension system having a knuckle that rotatably supports a wheel end assembly. The knuckle may include a first platform that may have a toe link mount, a second platform that may have a stabilizer bar mount, a brake torque plate that may facilitate mounting of a brake subsystem, or combinations thereof.

An air spring assembly for a vehicle having a damper body which is decoupled from the bellow of a piston, allowing the damper to rotate freely without inducing torsion into the piston. The design includes a two-piece piston having both an inner piston and an outer piston which are connected together, and a portion of the inner piston is positioned over the damper tube. The piston having the two-piece design allows for the two-piece piston to fully decouple from the damper without leakage. The inner piston retains a rotary O-ring which seals to a damper rod to keep air within the air spring assembly. The air spring assembly also includes a thrust bearing located between the inner piston and the top surface of the damper tube. The thrust bearing allows full decoupling from the inner piston and the damper, ensuring that there is no torsion translated to the bellow.

An air spring strut for a motor vehicle comprising an air spring with a shock damper for the spring-cushioning and damping of oscillations of a motor vehicle chassis, wherein the air spring comprises an air spring cover and a rolling piston, wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston, wherein the air spring cover comprises a damper bearing receptacle in which a damper bearing of the shock damper is arranged, and wherein the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached, wherein at least the damper bearing receptacle of the air spring cover is produced from a plastic material.

A method for making an air spring assembly, including the steps of providing a bellow, a support ring, and a guide tube. The support ring is positioned relative to a bellow adapter such that a portion of the bellow adapter extends through the support ring. The bellow is then positioned such that a portion of the bellow extends over the support ring and a portion of the bellow adapter. The guide tube is then positioned relative to the bellow and the support ring, such that a portion of the bellow extends into the guide tube and the guide tube is supported by the bellow adapter, and a portion of the guide tube is supported by a ridge support fixture. The first clamp and second clamp are then moved towards the guide tube, applying force to the guide tube, simultaneously forming a first crimp and a second crimp.

A decoupling bearing for a suspension strut or a pneumatic suspension strut may include a suspension strut cup and a connecting element that can be connected to a vehicle body. A damping element may be arranged between the suspension strut cup and the connecting element. The suspension strut cup may be connected to the connecting element by the damping element. Further, the damping element may be adhesively bonded to the connecting element and the suspension strut cup in a force-transmitting manner, and/or the damping element may be adhesively bonded to the connecting element and an intermediate element in a force-transmitting manner. The intermediate element may be connected to the suspension strut cup.

End member assemblies having a longitudinal axis are dimensioned for securement to a flexible spring member. The end member assemblies include a first end member with a first surface portion and a plurality of projections disposed in peripherally-spaced relation to one another about the longitudinal axis. A second end member includes a plurality of grooves dimensioned to receive one of projections. Gas spring and damper assemblies include a damper assembly and a gas spring assembly that includes an end member assembly as well as an end member assembly with a flexible spring member secured between the end member assemblies. A suspension system including one or more gas spring and damper assemblies is also included.
