| Research Abstract |
In this work structural simplification, compact, light and ecological design of a vehicle suspension is achieved by using a colloidal damper with a dual function of absorber and compression helical spring. Concretely, the classical suspension, consisted of an oil damper connected in parallel with a compression helical spring, is replaced by a colloidal suspension, in which case the spring and the oil are unnecessary. Thus, the oil is replaced by an ecological colloid consisted of water and hydrophobized porous silica gel (particles of artificial sand). In the same time, it is possible to achieve a simpler, lighter and compact design for both the internal and external structure of the vehicle suspension.
