摘要:
A rolling piston composed of plastic for an air spring U-type bellows (19), wherein the rolling piston (1) is formed as a plunger piston and has a preferably central support (2) for a stop buffer (3) which acts in an axial direction of the air spring, wherein the support (2) is composed preferably of steel and can be received in a recess, which is of complementary shape to the support, of the rolling piston and connected to the latter.
摘要:
The present invention relates to laminated membranes formed by multilayer processing techniques including alternating layers of thermoplastic urethane and a barrier material such as a copolymer of ethylene and vinyl alcohol. The membranes are characterised in that significant hydrogen bonding occurs between the layers of thermoplastic urethane and the barrier material. The membranes are specifically characterised in that hydrogen bonds are formed between the layer including thermoplastic urethane and the layer including at least one copolymer of ethylene and vinyl alcohol. Products in the form of cushioning devices made from flexible membranes employing at least one layer including thermoplastic urethane and at least one layer of a copolymer of ethylene and vinyl alcohol are inflatable to a relatively high pressure. The cushioning devices maintain the internal inflatant pressure for extended periods of time by employing a phenomenon referred to in the industry as diffusion pumping. Ideally, the cushioning devices of the present invention can be permanently inflated with gases such as nitrogen or air. Still other products such as bladders useful for inflatable objects, such as footballs, basketballs, soccer balls and inner tubes; food packaging films; fuel liner; fuel storage tanks and pressurised accumulators, among others, are formable utilising the laminated membranes described herein.

Torsion damper forming a dual damping flywheel with air flowing between the parts of two coaxial bodies. According to the invention, the second body (14) includes a disk (28) forming a plate rotatably linked by a bearing to the first body (12), an annular ventilation space (48) being formed between this disk, the platen (27) in the second body (14) and a disk (32) in the first body (12).
摘要:
A controllable vibration apparatus such as a linear fluid damper in which an electrical connection to a controllable valve, preferably located in the piston assembly, is made through a single-strand electrical conductor. In one embodiment, the piston and piston rod (24a) are preferably used as the source of low potential (ground or retun electrical path). An accumulator assembly (44a) preferably including a flexible diaphragm (76a) thereon can be used to provide separation of the fluid-containing chambers from a pressurized accumulator chamber. In magnetorheological (MR) fluid dampers, a special sealing system including a defined relationship between surface finish on the piston rod and magnetically soft particle size is described which enhances life of the seal system. A metal bushing (36a) with a friction-reducing surface treatment is used in combination with an energized lip seal (38a) to prevent escape of the magnetic particles from the damper and support side loads. The magnetically controlled valve can be formed from separate top (80a) and bottom (85a) pole pieces that are spaced from an outer annular ring (82a) to define a fluid passageway. The top pole piece and the annular ring can be secured together by bridging elements such as non-magnetic welds, spot welded plates, or alternatively, formed as a single unit using powdered metal processes such as PIM or MIM. The coil assembly (88a) can be configured with axially-extending pins (94a, 96a) to easily connect with a conductor. An elastomeric element (98a) provides electrical and fluid sealing engagement against the single-strand conductor. Push-on connectors (83a) preferably make the connection between the single-strand conductor and the axially extending pins. In a two single-strand conductor version, one single-strand carries the incoming current and the other the outgoing current.

摘要:
A flywheel comprising two coaxial members (1, 2) mutually rotatable counter to a torsional damper device (3) with a friction device (9) and a disc (31) attached to a reaction plate (21) of one of the members. The other member comprises an axially projecting centring nose (4) engaging centre bores in the disc (31) and the reaction plate (21). A sliding-contact bearing is located between said centre bores and the central nose (4) while the friction device (9) is housed in a recess defined mainly by the disc (31) and the plate (21). Application in motor vehicles.

Es wird eine Kupplungsscheibe für eine Kraftfahrzeug-Reibungskupplung vorgeschlagen, bei welcher eine Seitenscheibe (21) eines Last-Drehschwingungsdämpfers (13) der Kupplungsscheibe an Federzungen (51) radial zentriert gelagert ist, die von einer Nabe (5) der Kupplungsscheibe entweder axial oder in Umfangsrichtung verlaufend abstehen. Die Federzungen (51) greifen radial vorgespannt in eine zentrische Öffnung (47) der Seitenscheibe (21). Zur Begrenzung des Federwegs können in Umfangsrichtung zwischen den einzelnen Federzungen (51) radial wirkende Anschläge an der Nabe (5) vorgesehen sein.
