Abstract: The invention relates to a spring support for a coil spring (15), comprising an annular receiving element (5) having a top side and a bottom side, wherein the top side is provided to receive one end of the coil spring (15), and comprising an annular damping element (3), which is in contact with the bottom side of the receiving element (5), wherein the damping element (3) furthermore has on its inside a collar which extends from the bottom side of the receiving element (5) in the direction of the coil spring (15), and wherein the collar is formed by bending from a disk-shaped basic form of the damping element (3). The invention furthermore relates to a method for producing a spring support according to the invention, in which a disk-shaped damping element (3) is first of all placed in a casting mold, and an annular receiving element (5) is then produced by being molded or injection-molded to the damping element (3), with the result that the bottom side of the receiving element (5) is in contact with the annular damping element (3).

Abstract: The present invention relates to a method of preparing a polyurethane elastomer, said method comprising the step of reacting at least one isocyanate composition (ZI) and one polyol composition (ZP) comprising a poly-ε-caprolactone polyol and an α-hydro-ω-hydroxy-poly(oxytetramethylene) polyol to obtain an isocyanate-functional prepolymer and the step of reacting the prepolymer obtained as per step (i) with at least one chain extender (KV). The present invention further relates to a polyurethane elastomer obtained or obtainable according to a method of the invention and also to the method of using a polyurethane elastomer according to the invention or a polyurethane elastomer obtained or obtainable according to a method of the invention in the manufacture of a shaped article, especially a damping element, a shock absorber or a stop buffer or part of a shoe or of a shoe sole, for example part of an insert sole or of a midsole.

Abstract: The invention relates to a spring support (1, 1′, 1″) configured to receive a coil spring (50) of a motor-vehicle spring system (100), where the coil spring (50) has a length in the direction of a longitudinal axis (L) that is variable between a state of minimal compression and a state of maximal compression, and said coil spring comprises a terminal coil section (51) that rests on an annular surface of the spring support (1, 1″). An elastically deformable projecting element (18) is arranged between the annular surface of the spring support and the coil spring, and is configured to maintain contact with the terminal coil section (51) of the coil spring (50) during both maximal and minimal compression of the coil spring (50).

Abstract: The present invention relates to a method of preparing a polyurethane elastomer. The method includes a step of reacting at least one isocyanate composition and one polyol composition containing a poly-ε-caprolactone polyol obtained by reacting ε caprolactone and a diol having a number average molecular weight of from 80 to 1500 g/mol to obtain an isocyanate-functional prepolymer; and a step of reacting the prepolymer with at least one chain extender. The polyol composition contains α-hydro-ω-hydroxypoly(oxytetramethylene) polyols in an amount ranging from 0 to 1 wt % based on the entire polyol composition. The present invention further relates to a polyurethane elastomer prepared by such a method and also to the use of the polyurethane elastomer in the manufacture of a shaped article, especially a damping element, a shock absorber, a stop buffer, or a part of a shoe, such as a shoe sole, in particular, an insert sole or a midsole.
