Description

Pierwszenstwo: ' Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 25.11.1974 72473 KI. 20k, 4 MKPB60m.l/02 (czytelnia] 1 Urzedu Patentowego ^^m_ _j t 4 t Twórcywynalazku: Jerzy Zalopa, Jerzy Wolczyk, Leszek Bednarek Uprawniony z patentu tymczasowego: Osrodek Badawczo—Rozwojowy Pojazdów Szynowych, Poznan (Polska) Wezel uziemiajacy do pojazdów szynowych Przedmiotem wynalazku jest wezel uziemiajacy do pojazdów szynowych, w szczególnosci do lokomotyw elektrycznych, lokomotyw spalinowych z ogrzewaniem elektrycznym, jednostek elektrycznych oraz wagonów osobowych.Dotychczasowe rozwiazania wezla uziemiajacego charakteryzuja sie tym, ze powierzchnia szczotki przy¬ legajaca do plytki kontaktowej jest plaska, lecz nie zapewnia to wlasciwego styku, gdyz drganiamaznicy powoduja stozkowe scieranie sie szczotki a tym samym zmniejszenie powierzchni styku. Na koncu szczotki w wyniku scierania sie tworzy stozek, który ulega czesto odlamaniu.Celem wynalazku jest usuniecie tych wad, zapobiezenie nadmiernemu zuzyciu szczotek uziemiajacych oraz zapewnienie prawidlowego styku szczotki z plytka kontaktowa.Cel ten osiagnieto poprzez wydrazenie otworu w szczotce uziemiajacej od strony powierzchni stykajacej sie z plytka kontaktowa oraz przez nadanie tym stykajacym sie powierzchniom postaci czaszy kulistej.Zaleta tego rozwiazania jest równiez to, ze pozostale elementy wezla uziemiajacego pozostaja bez zmian, co umozliwia zalozenie szczotek i plytek kontaktowych wedlug wynalazku na pojazdach szynowych be dacych juz w eksploatacji.Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na rysunku, na którym szczotka uzie¬ miajaca 1 styka sie swa powierzchnia kulista z plytka kontaktowac. Szczotka od strony styku z wypukla czescia 3 plytki kontaktowej ma wydrazony otwór 4.

Previous solutions of the grounding node are characterized by the fact that the surface of the brush adjacent to the contact plate is flat but This does not ensure proper contact, as the vibrations of the moth cause the brush to taper, thus reducing the contact surface. At the end of the brush, abrasion forms a cone that is often broken off. The purpose of the invention is to remove these defects, prevent excessive wear of the grounding brushes and ensure proper wear. the contact between the brush and the plate This goal was achieved by making a hole in the grounding brush on the side of the contact plate and by making these contacting surfaces a spherical bowl. The advantage of this solution is also that the remaining elements of the grounding junction remain unchanged, which allows the installation of the brushes and contact plates according to the invention on rail vehicles already in service. The subject of the invention is shown in an exemplary embodiment in the drawing, in which the grounding brush 1 contacts its spherical surface with the plate. The brush on the side of contact with the convex part 3 of the contact plate has a protruding hole 4. PL PL
