A closure package for a vibration damper may include a base body that is connectable to a damper tube and comprises a first end and a second end. The first end forms an end side of the damper tube and the second end is disposed in the damper tube. A seal for sealing a piston rod may be disposed in the base body. A seal holder may be disposed between the seal and the base body at the first end. The seal holder for axially fixing the seal may be connected to the base body in a form-fitting and/or force-fitting manner. The seal holder may be fusible in an emergency. For releasing the connection to the base body, the seal holder may be thermoplastically deformable upon overheating of the vibration damper.

The first nozzle disc may include a sealing member made of a second material and abut the second nozzle disc to seal the damping channel. A hydraulically damping mount for mounting a motor vehicle unit may having a separating device.

A drive assembly for a motor vehicle includes a drive, a transmission that can be driven by the drive, a drive housing, a transmission housing, and a fastening device. The drive is arranged in the drive housing, and the transmission is arranged in the transmission housing. The drive housing or the transmission housing can be fastened on a carrier by way of the fastening device. The fastening device includes a plurality of vibration dampers and sleeve elements. The sleeve elements surround the vibration dampers.

An insulator for a vehicle suspension and a method of manufacturing the same, may include an insulator having a housing which is configured to be engaged with a vehicle body and in which a hook protrusion is formed to protrude from an upper end opening of the housing; a bush which is configured to be engaged with a piston rod of a shock absorber, wherein a vibration-proof rubber, a core, and an outer pipe are integrally mounted in the bush, and wherein the bush is press-inserted into and fixed in an inner space of the housing so that the bush becomes hooked upward to the hook protrusion; and a fixing plate press-inserted into and fixed in the inner space of the housing so that the fixing plate is in contact with a lower end portion of the bush and supports the bush from a lower side thereof.

An isolation coupler for coupling a functional element to a support structure includes a first bracket. The first bracket includes a number of first-bracket sides. The number of first-bracket sides forms a closed polygonal shape, in plan view. The isolation coupler further includes a number of isolators coupled to each one of the first-bracket sides. The isolation coupler also includes a second bracket. The second bracket includes a number of second-bracket sides. The second bracket sides are coupled to the isolators. The number of second-bracket sides is equal to the number of first-bracket sides and forms the closed polygonal shape, in plan view. The isolators separate each one of the first-bracket sides from a corresponding one of the second-bracket sides to attenuate a load transferred from the first bracket to the second bracket.

A damper assembly comprises a main tube defining a fluid chamber. The main tube includes a first section, a second section, and an intermediate portion. A sleeve is disposed about the main tube. An external tube is disposed about the main tube and the sleeve. The external tube defines a compensation chamber between the sleeve and the external tube. A main piston divides the fluid chamber into a rebound chamber and a compression chamber. A piston rod couples to the main piston for moving the main piston between a compression stroke and a rebound stroke. The sleeve is in an abutment relationship with the second section of the main tube, radially spaced apart from the first section of the main tube, defining a compartment extending between the sleeve and the first section of the main tube. A housing for the damper assembly is also disclosed herein.

An elastomeric bearing includes an inner member that has a spherical exterior surface and is symmetric about a central axis and a hollow annular outer structure that is axially split thereby forming a first outer segment and a second outer segment. The first outer segment and second outer segment form a substantially cylindrical exterior surface. One or more shim structures are formed around the inner member and are disposed at least partially inside the hollow annular outer structure. The shim structure has a radially outward facing surface and a radially inward facing surface. One or more layers of elastomeric material are disposed on each of the radially outward facing surface and the radially inward facing surface.

A damper with inner and outer tubes and a piston disposed within the inner tube to define first and second working chambers. A fluid transport chamber is positioned between the inner and outer tubes. A collector chamber is positioned outside the outer tube. An intake valve assembly, abutting one end of the inner tube, is positioned inside the outer tube to define a first intermediate chamber that is arranged in fluid communication with the collector chamber. The intake valve assembly includes a central passage that is arranged in fluid communication with the second working chamber and one or more intake valves that control fluid flow through the intake valve assembly between the first intermediate chamber and the central passage and between the first intermediate chamber and the fluid transport chamber.

The invention relates to an air spring having: a rolling bellows (1) with an opening which has a bead (2) reinforced by a core (3) and a rolling piston (4) with a seat (5) for the rolling bellows (1) and a support shoulder (7) for the rolling bellows (1),

wherein when the rolling bellows (1) is in the mounted state, its end assigned to the rolling piston (4) is connected to the rolling piston (4) in an airtight manner by means of a clamping fit between the bead (2) and the seat (5) of the rolling piston (4), and the bead (2) of the rolling bellows (1) rests at least partly on the support shoulder (7), wherein the rolling piston (4) is made of a thermoplastic material. The object of the invention is to improve an air spring of the type outlined above such that the bellows (1) can very reliably and simply be prevented from slipping off the piston (4), in particular in view of the use of plastic as the piston material. This is achieved in that on the seat (5) for the rolling bellows (1), the rolling piston (4) has an axially protruding, substantially cylindrical securing ring (8), which protrudes axially beyond the bead (2) of the rolling bellows (1) after mounting of the rolling bellows (1) on the seat (5), can be plasticized by an at least partial heating process, and in the plasticized state can be deformed radially outwardly over the bead (2) of the rolling bellows (1) by means of a forming die (9, 10, 11) such that the bead (2) is at least partly surrounded by the deformed securing ring (8).
