An airshock assembly is disclosed. The airshock assembly includes a shock absorber an airspring, and an air compressor assembly. The airspring is axially coupled with a portion of the shock absorber and used to modify a ride height of the shock absorber. The air compressor assembly is coupled with a portion of the shock absorber. The air compressor assembly is used to modify an air pressure in the airspring without requiring the airshock assembly to utilize an air reservoir.

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. The air spring cover comprises a damper bearing receptacle in which a damper bearing of the shock damper is arranged, and the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached. At least the damper bearing receptacle of the air spring cover is produced completely from a plastic material, and the plastic material is a thermoplastic.

A gas spring and damper assembly includes a damper assembly and a gas spring assembly. The gas spring assembly is axially coextensive with the damper assembly and includes a flexible spring member, a first end member assembly and a second end member assembly. The first end member assembly includes a first wall portion that extends about a longitudinal axis and defines an end member chamber. A second wall portion projects outwardly beyond an outer peripheral surface portion of the first wall portion. The second wall portion at least partially defines an intermediate chamber in fluid communication with the end member chamber and is dimensioned to receive an associated control device. A third wall portion at least partially defines an end member passage through which the end member chamber can be selectively placed in fluid communication with the spring chamber by way of the intermediate chamber and the associated control device.

A device for fastening an air spring to a body portion of a motor vehicle, at least comprising an air spring cover, wherein the air spring cover comprises at least one fastening means, by means of which the air spring can be connected to the body portion of the motor vehicle, wherein, for attachment of the air spring, the fastening means is plugged through an opening of the body portion and is fixed to said body portion in a force-fitting manner by a securing element, wherein a first and a second plastics part are provided for acoustic decoupling of the air spring, wherein the first plastics part, is clamped between the body portion and the securing element, and the second plastics part is provided so as to be positioned below the body portion.

An air suspension strut for a motor vehicle, comprising an air spring having a shock, 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 rolling bellows, together with the air spring cover and the rolling piston, delimit a working chamber filled with compressed air, wherein the shock damper is supported via a damper bearing arranged on a piston rod in a pot-shaped bearing holder of the air spring cover. The closure cap seal comprises an inner sleeve and a closure part radially enclosing the inner sleeve, wherein the inner sleeve is pushed onto an end section of the piston rod, and the closure part is pushed sealingly into the bearing holder.

A vehicle shock absorber has a body extending between a first end and a second end. Translation of a primary shaft within an interior cavity of the body communicates a first volume of fluid within the interior cavity to a secondary reservoir where it increases pressure in a gas cavity therein. The primary shaft has an annular member engaged thereon which contacts a bump shaft slidably located in an opening at the first end of the body. The contact of the annular member translates the bump shaft within the interior cavity to cause communication of a secondary volume of the fluid to the secondary reservoir.
