SLIDING CAM ARRANGEMENT FOR VARIABLE ACTUATING GAS EXCHANGE VALVES OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a sliding cam arrangement for variable actuation of gas exchange valves of an internal combustion engine, which exhibits improved dynamic behavior.SOLUTION: Provided is a sliding cam arrangement for variable actuation of gas exchange valves of an internal combustion engine, having a camshaft (6) which has toothing regions (10) with an external toothing (12). The toothing regions (10) mesh in each case with an internal toothing (14) of a cam carrier (16). The ratio of the base circle radius R2 of the cam carrier (16) to the tip circle radius R1 of the toothing (12) of the camshaft (6) satisfies the following criteria: R2/R1<1.55.
