Abstract

Bei einem Herzstück (1) mit einer Herzspitze (2) aus gegosse­ nem Hartmanganstahl, bei welchem im Überlaufbereich ein Teil der Flügelschiene (3) an die Herzspitze (2) angegossen ist, weist das Herzstück (1) quer verlaufende Stege (9) im Bereich der Schwellen auf, wobei die Stege (9) unmittelbar an den Schwellen oder Unterlagsplatten abstützbar sind, und das Herzstück (1) ausschließlich über die Stege (9) an den Schwellen abgestützt wird, wodurch bei hoher Stabilität und kleinen Abmessungen des Herzstückes eine hohe Präzision der Lage der Fahrkanten und der Herzstückspitze (2) ohne aufwen­ dige Einpassarbeiten erzielt wird. With a heart (1) with a heart tip (2) made of cast Hard manganese steel, in which a part is in the overflow area the wing splint (3) is cast onto the heart tip (2), the centerpiece (1) has transverse webs (9) in the area the thresholds, the webs (9) directly on the Thresholds or underlay panels can be supported, and that Centerpiece (1) only via the webs (9) to the Thresholds is supported, which ensures high stability and small dimensions of the centerpiece a high precision of the Position of the driving edges and the centerpiece tip (2) without expending fitting work is achieved.
