Embodiment

[0034] exist figure 1 An embodiment of a spring carrier 1 according to the invention is shown in longitudinal section. In this embodiment, the component is configured to be rotationally symmetrical about an axis shown in dotted lines. The spring carrier 1 comprises a thermoplastic-based annular receiving element 5 . In one embodiment, based on thermoplastic polyurethane (trade name Depend on BASF Polyurethanes GmbH) material is added, while in another embodiment a polyethylene-based material is added. The receiving element 5 has a top side and a bottom side. A top side is provided for receiving one end of the coil spring. In this embodiment, the area 7 provided for receiving the spring is configured as an annular cavity formed by the clamping element 9 . The clamping element 9 is integrally connected to the body of the element 5 and has a gap at the top end of the clamping element 9 through which the helical spring can be pressed into the cavity 7 .

Abstract

The invention relates to a spring support for a helical spring (15), comprising an annular receiving element (5) with a top side and a bottom side, and comprising an annular damper in contact with the bottom side of said receiving element (5) element (3), said top side is arranged to receive one end of said helical spring (15), said damping element (3) also has a collar on its inner side, said collar from said receiving element ( The bottom side of 5) extends in the direction of the coil spring (15), and the collar is formed by bending from the disk-shaped basic shape of the damping element (3). The invention also relates to a method for producing the spring carrier according to the invention, wherein the disc-shaped damping element (3) is first inserted into a mold and the ring is subsequently produced by casting or injection molding on the damping element (3) shaped receiving element (5) so that the bottom side of said receiving element (5) is in contact with the annular damping element (3).

Description

technical field [0001] The invention relates to a spring carrier for a helical spring, said spring carrier comprising an annular receiving element with a top side and a bottom side, and comprising an annular damping element in contact with the bottom side of said receiving element, wherein The top side is adapted to receive one end of the coil spring. Background technique [0002] Spring mounts of the general type are well known for use inside the chassis of motor vehicles. They are used in wheel suspension systems to hold coil springs in their intended positions between the vehicle body and its chassis parts. In addition to the fastening of the coil springs, the spring mounts usually also take over the task of damping or decoupling the oscillations resulting from driving on more or less uneven roads. At the same time, it should also be ensured that the coil springs and body parts are not in direct contact. In interaction with other chassis components, they play an import...
