Abstract

In un procedimento per la produzione di un portasatelliti (1), in particolare per ammortizzatori torsionali idraulici, da un corpo di base fuso, di forma anulare, questo viene prodotto nel procedimento cold-box con anime per cavità (2, 3) inserite nel portasatelliti (1). In un'ulteriore fase le cavità (2, 3) vengono portate alle dimensioni finali precise nel procedimento di brocciatura.Descrizione del trovato L'invenzione concerne un procedimento per la produzione di un portasatelliti, in particolare per ammortizzatori torsionali idraulici, di un corpo di base di forma anulare, ottenuto per colata. Ammortizzatori torsionali idraulici vengono impiegati, tra l'altro, nel campo degli autoveicoli e dei natanti e nella costruzione di macchine in generale. Un possibile campo di impiego è, per esempio, la disposizione nel flusso di trasmissione di azionamento diIn a process for the production of a satellite holder (1), in particular for hydraulic torsional shock absorbers, from an annular-shaped base body, this is produced in the cold-box process with cavity cores (2, 3) inserted in the satellite holder (1). In a further step the cavities (2, 3) are brought to the precise final dimensions in the broaching process. Description of the invention The invention relates to a process for the production of a satellite holder, in particular for hydraulic torsional shock absorbers, of a body of annular base, obtained by casting. Hydraulic torsional shock absorbers are used, among other things, in the field of motor vehicles and boats and in the construction of machines in general. One possible area of use is, for example, the arrangement in the drive transmission flow of
