Abstract: A piston for use in forming a gas spring assembly includes a longitudinally extending axis, a first end wall extending approximately transverse to the axis, and an outer side wall extending longitudinally from adjacent the first end wall. The outer side wall includes a first side wall portion that forms a fully circumferential outer surface and a second side wall portion that forms a partially circumferential outer surface that extends longitudinally beyond the fully circumferential outer surface. A gas spring assembly including such a piston is also included.

Abstract: A cooperative mounting arrangement for an end member or spacer of a gas spring assembly includes a recess formed into one of the end member and the spacer. A projection is provided on or along an associated structural component. The recess receives the projection such that lateral forces acting on the end member of the gas spring assembly can be transferred to the associated structural component.

Abstract: A turn-up device (40) for making a molded body of an airspring on a mechanical drum having expandable end portions. The device (40) comprises a support member (42), a plurality of turning arms (44) pivotally mounted to the support member (42), and a sleeve (46) resiliently mounted to the support member (42). The turning arms (44) are movable between radially inner and outer positions and are biased to the radially inner position. The sleeve (46) is movable relative to the arms (44) between a position whereat it holds the arms (44) in the radially outer position and a position whereat it releases the arms (44) so that they can be biased to the radially inner position. The airspring can be used in a large vehicle wheel suspension (i.e., a bus or a truck) and/or can be used to manipulate the lift axle of, for example, a large dump truck.
