摘要： A vehicle air spring assembly has a pair of spaced end plates which sealing engage a bladder to form an air chamber. A pair of bead skirts are attached to the end plates to guide the bladder radially outwardly as the air spring is compressed. By guiding the bladder as it expands radially outwardly, the bead skirts control the effective area with respect to the air spring height, thus controlling the dynamic load and dynamic spring rate of the air spring. The bead skirts are formed complementary in shape and nestle together as they move towards one another. This nestling reduces pinching of the bladder when the air spring is compressed during use.

摘要： An integral one-piece end plate and bracket combination is formed of a high strength plastic and is mounted in an airtight sealing engagement with an open end of a flexible elastomeric sleeve which forms the fluid pressure chamber of an air spring. The end plate includes a semi-circular wall which extends perpendicular to a longitudinal axis of the air spring and a semi-circular opening. The bracket includes an upstanding wall perpendicular to the semi-circular wall of the end plate and a half dome-shaped wall, which together with the upstanding wall, forms an auxiliary fluid chamber which is in fluid communication through the semi-circular opening with the main fluid chamber of the flexible sleeve. The upstanding wall includes attachments for securing the bracket and end plate to a support structure which aligns with a longitudinal axis of the air spring. A fluid inlet conduit extends outwardly from the upstanding bracket wall to provide fluid communication between the auxiliary fluid chamber of the bracket and an external source of pressurized fluid. A plurality of reinforcing ribs are formed on the walls of the bracket and on the end plate to provide a rigid structure.

摘要： The air spring is comprised of a flexible airsleeve, a retainer, and a main piston. The airsleeve is secured at one end by the retainer and at the opposing end by the main piston. A hollow restraining piston extends from the retainer and into the main piston. The restraining piston acts as a lateral stabilizer, over extension restraint and height control. The hollow region in the restraining piston communicates through at least one passage with an air chamber formed between the airsleeve and the outer surfaces of the restraining piston and the main piston. Fluid is admitted to or exhausted from the air spring through a valve which functions relative to the displacement of the restraining piston and the main piston.

摘要： A dual volume air spring for a truck suspension, which has an air bag chamber providing a variable volume and a fixed volume chamber. The chambers are interconnected by a closable orifice. The air bag is provided with a post-like orifice closer which is pushed into the orifice when the air bag is sufficiently compressed ad withdrawn from the orifice when the air bag is not compressed. In normal operation the orifice is open and the combined volumes of the chambers are available resulting in a low spring rate. The orifice closer has an orifice closing portion which is relatively pliant and a rigid or semi-rigid portion which acts as a bump-stop when the pliant portion is substantially completely compressed. When the orifice is completely closed the spring has a high spring rate.

摘要： This invention concerns a pneumatic spring consisting of a hose roll bellows of elastomer material which is equipped, in particular, with stiffening supports. The ends of the hose roll bellows are pushed onto a connecting element and attached there by a radially ductile clamping ring particularly made out of metal. According to the invention, the connecting element and/or clamping ring are made thicker with a covering elastomer strip in the area of clamping. The elastomer strip is a component which is separate from the hose roll bellows. Several variants are presented.
