Intermediate lever for a variable valve train of an internal combustion engine
摘要:
The invention proposes an intermediate lever (1) for a variable valve train of an internal combustion engine, said intermediate lever (1) comprising a loading end (2) and a pivoting end (3), a cam contacting surface (4) and a support (5) for a resetting spring (6), the loading end (2) extending on a front end of the intermediate lever (1) and comprising a sliding surface (7) for making contact with a lever-type valve opener, the pivoting end (3) being designed so as to cooperate with eccentric means for effecting a change of position of the intermediate lever (1), and the cam contacting surface (4) being arranged between the loading end (2) and the pivoting end (3), wherein the intermediate lever (1) is made of a thin-walled sheet metal and is manufactured substantially by a punching plus bending method and wherein the support (5) is arranged on an upper side (8, 9) of the intermediate lever (1) in an edge region (10) adjoining the loading end (2) and has a convex portion extending towards the upper side (8, 9) for contact by a leg (11) of a torsion spring constituting the resetting spring (6), said support (5) being laterally delimited by two guide tabs (12, 13).
