Abstract
A spring assembly for a vehicle chassis may include a spring that features a coating, a spring support, and an intermediate layer. The intermediate layer can be arranged between the spring and the spring support. The intermediate layer may be at least materially connected to the spring, in particular to the coating on a side facing the spring. The intermediate layer lies entirely or partially against the spring support on a side facing away from the spring and is connected to the spring support by a connection other than a material connection.

1-15. (canceled)
A spring assembly for a vehicle chassis, comprising:
- a spring that has a coating, a spring support, and an intermediate layer, wherein the intermediate layer is arranged between the spring and the spring support, wherein the intermediate layer is at least materially connected to the coating on a side facing the spring, wherein the intermediate layer lies entirely or partially against the spring support on a side facing away from the spring and is connected to the spring support by a connection other than a material connection, wherein the connection is a positive connection, wherein the positive connection is configured with a positive element and a negative receptacle that receives the positive element, wherein either
- the intermediate layer is received as the positive element in cavities of the spring support that form the negative receptacle, or
- projections with undercuts of the spring support form the positive element, with the positive element being received in the negative receptacle, wherein cavities in the intermediate layer form the negative receptacle.
A method for producing a spring assembly for a vehicle chassis, the method comprising:
- a) providing a spring that has a coating;
- b) providing a spring support that has an adhesive-repellent supporting region for supporting the spring;
- c) providing a filler;
- d) applying the filler to the spring and/or to the adhesive-repellent supporting region of the spring support;
- e) producing an intermediate layer between the spring and the spring support by bringing into contact
- i) the spring with the adhesive-repellent supporting region of the spring support, to which supporting region the filler has been applied,
- ii) the spring, to which the filler has been applied, with the adhesive-repellent supporting region of the spring support, or
- iii) the spring, to which the filler has been applied, with the adhesive-repellent supporting region of the spring support, to which supporting region the filler has been applied;
- and
- f) forming a material, adhesive connection between the intermediate layer produced in step (e) and the spring, wherein a connection other than a material connection is formed between the adhesive-repellent supporting region of the spring support and the intermediate layer produced in step (e).
