Abstract

Boghiul pentru vagon de marfa folosit pe calea ferata este format dintr-o pereche de cadre laterale, distantate si rezemate pe o pereche de osii cu roti montate. în scopul cresterii rigiditatii boghiului reducerii unghiului de înclinare a penei, maririi fortei arcului amortizor si reducerii rotirii orizontale si verticale a penei legatura între organul purtator în care sunt practicate niste locasuri de îmbinare si pana de frictiune este strînsa pentru a împiedica rotirea între elementele purtaoare si pana de frictiune care poate fi formata dintr-o singura bucata sau din mai multe semipene. locasul de amplasare a penei sau semipenelor au o suprafata de fund plana sau profilata cu orientare conjugata între perechile de locasuri. Niste suprafete adiacente plane sau profilate ale penelor sau semipenelor au pante conjugate cu cele ale fetelor corespondente din locasurile de asamblare.
