Problems solved by technology

[0003] Due to the high material thickness of the known spring backing plates, they are very heavy and have high production costs due to the material used and the long cooling or vulcanization times required
The recesses introduced into the spring backing only slightly reduce weight and mass accumulation However, additional recesses are not possible for mold-technical reasons without reducing the strength of the gasket in an unreliable manner

Embodiment Construction

[0031] figure 1 The spring backing plate 10 according to the invention is shown in the mounted state in a strut housing of a motor vehicle shock absorber. especially available from figure 1 As seen in (b), the end of the shock absorber spring 11 is partially accommodated in the spring backing plate 10, where it rests against, for example, image 3 at the spring support element 14 shown in .

[0032] exist Figure 2-4 The detailed construction of the spring washer 10 according to this embodiment is shown in . In addition to the above-mentioned spring support element 14 , the spring backing plate 10 has a holding element 12 , wherein the two components 12 , 14 are connected to one another in a form-fitting manner. The holding element 12 consists of a thermoplastic such as polyamide with a high glass fiber content (approximately 30% to 50%), while the spring support element 14 consists of an elastomer such as styrene-butadiene rubber (SBR) constitute.

Abstract

The invention relates to a spring support (10), particularly for a spring hanger of a motor vehicle comprising an annular retaining element (12) made of a thermoplastic material and a spring support element (14) made of an elastomer material applied to the retaining element (12), wherein the retaining element (12) comprises at least one closed hollow space (18). The invention further relates to a method for producing such a spring support (10), wherein the method comprises introducing a melt of a thermoplastic material into an injection mold comprising at least two mold cores for configuring at least two through-openings (16) in the thermoplastic material, injecting an expansion material for configuring a closed hollow space (18) in the melt of the thermoplastic material and applying an elastomer material to the thermoplastic material. During the step of injecting the expansion material, the at least two mold cores are cooled and the expansion material is injected into at least two regions of the thermoplastic material separated from each other by the at least two mold cores, in order to implement one closed hollow space (18) in each of said regions.

Description

technical field [0001] The invention relates to a spring mount, in particular for a spring seat of a motor vehicle, and to a method for producing such a spring mount. Background technique [0002] Spring spacers are known from the prior art, which are used to accommodate the shock absorber springs at the body of the motor vehicle (at the shock strut housing) and contain in the middle a spring through which the shock absorber is guided. hole. The known spring backing plate consists of a solid thermoplastic molded part with a material thickness of up to 17 mm, into which a likewise very strong elastomer component is injected in the insertion method and thus form-fitted ground is held at the thermoplastic molding. Here, the thermoplastic component serves for the correct placement of the spring backing plate in the strut housing and provides support, especially at the sides, for the elastomer component, which itself accommodates the ends of the shock absorber springs and provi...
