This proposal is addressed to obtain integrated security sub-modules (constituting the suspension and steering module) in the car manufacturing industry. The final objective is to give SMEs an advantageous a roach to the modularisation requirements nowadays demanded in the sector. The sub-modules are made up of a steel structure and anchorage elements (rubber-metal or plastic-metal), which undergo separate surface treatments to prevent corrosion. Afterwards, the elements are traditionally joined by means of adhesives and screws. This process supposes a great number of stages, low quality union methods and generation of corrosion nucleuses that shorten its useful life. This proposal would change this work methodology. The first point in its implementation would be the construction of metallic structure in high strength low alloy steel (HSLA), instead of traditional one, in order to profit from its safety performance and lower weight at affordable cost. Once this done, the improvement proposed is based on the use of laser welding as joint method, a high quality way to reduce anchorage points and to increase the resistance of the sub-module.
Thus, it would achieve a completely integrated, lighter and reliable security sub-module The further surface treatment of the integrated piece will provide an unaltered coating. Overcoming the currently need of assembly processes, which usually cause serious damages on the protective surface, will suppose an improvement in the response against corrosion of the pieces. In order to be applied to the sub module, the traditional treatment would have to be modified so as to respect the different natures of its elements, ie, steel, rubber and thermoplastics With regards to this aspect, it is proposed the development of an organic treatment with lower required temperatures (max 100°C), drawing particularly the attention to the removal of pollutant elements (Cr (VI), Zn and Ni) involved in traditional methods...
