With its level control, the pneumatic vehicle suspension increases driving stability with changing loads and loading conditions and enables the vehicle to drive over obstacles on rough terrain, kerbs, underground garage entrances, height-restricted access roads, ferries, bridges and other obstacles.
At Schröder, we know the high loads that suspension components are exposed to. And yet we still manage to reduce the use of materials, simplify production processes and guarantee quality. Transparent and seamless.
We would be happy to talk to you.
Our products for pneumatic vehicle suspension vary in complexity. We supply simple pistons with an overmoulded ring for stabilization, but also air suspension covers with a variety of individual assembly and testing processes.
Thanks to our very high degree of automation, our know-how and our flexibility, we are experts in all air suspension components.
A key production step for air spring covers is the joining of two housing halves using hot gas welding. The joining zones of the complex geometries of air spring pots are plasticized and joined together without particle formation or thermal damage.
We use special test procedures for highly resilient and safety-relevant components. One example is the burst test, in which a sealable housing is tested for tightness and pressure resistance. These procedures are also often very useful for welded parts, such as hydraulic connections.
Helium is non-toxic and does not react with other materials. The ‘small’ gas molecule is inert and can therefore be used safely without reacting with any of the materials inside the part being tested. The small atomic radius enables fast testing and detection of even the smallest leaks. We also use a recovery system to reduce costs.
We offer the entire package from the first simulation to series production and assemble the vehicle suspension components largely fully automatically. Following the injection molding of the complex multi-chamber air suspension pots, we screw together Voss fittings, assemble connecting pins after pre-heating, join housing halves using hot gas welding, label components – and carry out close-meshed product testing during production.
Complete traceability and protection against liability claims: Lasering a data matrix code has long proven its worth. In contrast to one-dimensional barcodes, DMCs’ require less contrast for machine readability and are more error-tolerant. This method is particularly suitable for sensitive, safety-relevant thermal management components. During assembly, we assign codes for each individual part as well as for the final assembly.
As part of the international OKE Group, we develop and produce components and sub-assemblies for thermal management applications. We currently use the following technologies at our site in Herscheid:
