The present invention relates to a stopper (10) for vehicle which is disposed between a vehicle body side member (31) and a wheel side member (32) to restrict a relative amount of movement of both members (31, 32). The stopper includes a cylindrical holding member (11) attached to one of both members (31, 32), and an elastic body (12) which faces the other of both members (31, 32). A folded-back portion (18) bent outward in the radial direction of the holding member (11) and folded back is formed in the holding member (11).

An axle-to-beam connection for an axle/suspension system of a heavy-duty vehicle that includes an axle, a beam with an alignment assembly, and an axle mount assembly. The alignment assembly is integrally formed with or is rigidly attached to the beam. The axle mount assembly intimately contacts and captures the axle. The axle is rigidly secured to the axle mount assembly without line welds. The axle mount assembly is removably connected to the alignment assembly to secure the axle to the beam.

A bump stop for a suspension system. The bump stop comprises an outer shell around an internal structure; and one or more ports. The outer shell retains air within the bump stop. Air is vented through the one or more ports. The internal structure includes a variable density infill structure. The outer shell is detached from the internal structure at one or more locations. A core includes sidewalls with accordion-style bellows. A base region has a higher density than the internal structure.

End member assemblies are dimensioned for securement to an end of a flexible spring member for forming gas spring assemblies. An end member assembly can include an end member body and at least one connector fitting. The end member body includes a base section and a cap section that are secured together at a single flowed-material joint. The base section and the cap section together at least partially define a reservoir chamber within the end member body. The at least one connector fitting is at least partially embedded within the end member body. Gas spring assemblies including at least one end member assembly and suspension systems including at least one gas spring assembly are also included.

A suspension includes a knuckle to which a wheel of a vehicle is fastened, a steering drive portion connected to the knuckle, a lower arm positioned at a lower end portion of the steering drive portion and including a first end portion connected to the knuckle and a second end portion connected to a vehicle body frame, a connecting link including a first end portion connected to an upper end portion of the steering drive portion, an upper arm connected to a second end portion of the connecting link, a damper connecting the upper arm and the vehicle body frame, and a push rod including a first end portion connected to the upper arm and a second end portion connected to the lower arm.
