Abstract

Vorgeschlagen ist ein Schwinghebel (1a, 1 b) für einen hubvariablen Ventiltrieb einer Brennkraftmaschine. Der Schwinghebel weist stirnseitig eines ersten Endabschnitts (3) eine um eine Schwingachse (8) verlaufende Abstützfläche (9), stirnseitig eines zweiten Endabschnitts (5) eine mit dem Schwinghebel starr verbundene Hubübertragungsfläche (10) für einen Ventilhebel und in einem Mittelabschnitt (13) eine Nockenanlauffläche (14) auf. Dabei sollen die Abstützfläche und/oder die Nockenanlauffläche als mit dem Schwinghebel starr verbundene Gleitflächen (7, 18) ausgebildet sein.
