A vibration damper includes a damping element and a pneumatic spring, where the damping element has a container tube, a fastening part, and a piston rod, and where the pneumatic spring consists of a spring bellows acting as a roll bellows, an outer tube connected to the mass whose vibrations are to be minimized, and a roll-over tube carrying a roll-over profile. The spring bellows forms one boundary of an elastic space filled with a pressurized gas, whereas the roll-over tube seals off the gas space from the container tube and is attached thereto. A stamped and formed support ring, which supports the roll-over tube on the container tube and serves to suppress tilting movements, is installed between the container tube and the roll-over tube.

A shock absorber includes a damping element and an air spring, the damping element having a container tube, a fixing part and a piston rod. The air spring has a spring bellows acting as a rolling bellows, an outer tube connected to a mass to be held with little oscillation, and a rolling tube bearing a rolling profile. The spring bellows bounds a gas chamber provided with a gas filling under pressure, while the rolling tube seals off the gas chamber with respect to the container tube and is fixed to the latter in the axial direction. Between the container tube and the rolling tube there is arranged a compression stop cap having three webs and thickened ends, which serve as a stop on the container tube for the rolling tube and to dissipate the radial force component acting on the latter.
摘要:
Multilayer plastic composites containing at least two incompatible plastics, A and B, in which the layering sequence alternates between A and B, the layers of plastic B are discontinued at regular intervals, and the resulting gaps in the layers are filled in with plastic A, exhibit good adhesion between the layers. In preferred embodiments of the invention, the amorphous, crystalline, or semi-crystalline plastic B has a higher coefficient of thermal expansion than the amorphous plastic A. The plastic composite is preferably produced via coextrusion.

In a weight sensor operating according to the principle of electromagnetic force compensation, the essential parts are fabricated from a single block of material. The weight sensor has a load receiver (10), which is connected through an upper guide (12) and a lower (11) guide to the housing-integral base body (1) of the material block. The weight sensor also has several force-reduction translating levers (21,22; 24, 25,25′; 27,27′,28) and coupling elements (18,18′, 23, 26,26′) between the translating levers (21, 22; 24 ,25,25′; 27,27′,28). The housing-integral base body (1) projects in the direction of the load receiver (10), extends into the space between the two guides (11, 12) and forms a support point for the first translating lever (21, 22). The weight sensor is equipped with a coil (34), which is fastened at the longer lever arm (28) of the last translating lever (27,27′,28,29,29′) and is situated in the magnetic field of a permanent magnet. To reduce the overall height and to receive higher loads, at least one translating lever is at least partially split into two partial levers (25, 25′; 27,27′; 29,29′). At least one coupling element is split into two partial coupling elements (26,26′; 38,38′). The partial levers and the partial coupling elements are arranged symmetrically on both sides of the projecting part (3) of the base body (1).
