Valve control for at least one of an internal combustion engine

摘要

Valve control for at least one valve of an internal combustion engine, in which the movement of at least one cam (2) of a camshaft (3) can be transmitted to a valve stem (5) of the valve (1) by a transmission mechanism (4), the transmission mechanism (4) including at least one transmission element (7) which is mounted rotatably on an axis (6) and is preferably designed as a rocker arm (10) or drag lever and which is connected to the camshaft (3) via a contact element (8) arranged on the transmission element (7), the contact surface (19) of the contact element (8) and the circumferential surface (20) of the cam (2) having, at least in regions, curved and mutually corresponding contours in the axial direction (21), and the transmission element (7) being mounted axially moveably on an axial body (11) of the axis (6).

主权项

1. A valve control for at least one valve for an internal combustion engine comprising:
a rotatable camshaft (3) including at least one cam (2); an axis (6) and an axial body (11); a transmission mechanism for transmitting a movement of said at least one cam (2) to a valve stem of the at least one valve, said transmission mechanism comprising at least one transmission element (7) mounted rotatably and axially moveable on said axial body (11); a contact element (8) arranged on said transmission element (7) for connecting said transmission element (7) to said camshaft (3); said contact element (8) having a contact surface (19) and said at least one cam (2) having a circumferential surface (20), said contact surface (19) and said circumferential surface (20) having, at least in regions, curved and mutually corresponding contours in an axial direction configured so as to provide a form-fit between said contact surface (19) and said circumferential surface (20) of said cam (2)and to maintain the axial position of said transmission element (7) on said axial body (11); and wherein said contact element (8) is constructed as a roller body (17) mounted on said transmission element (7) for rotation about a roller body axis (18), said contact surface (19) constructed as a circumferential surface (22) of said roller body (17).
