Vorrichtung zum Verändern der Steuerzeiten einer Brennkraftmaschine

摘要

In a device (1) for varying the valve-timing of an internal combustion engine arranged inside a control drive of at least one camshaft, its drive wheel is to be secured on a component (3) on the side of the device economically and by simple means. According to the invention, a drilling (14) in the drive wheel (2) is to have knurled-like toothed sections (15). The drive wheel (2) is secured to the component (3) via these sections (15) so as to project and be secured against rotation.
