Vorrichtung zur Drehwinkelverstellung

摘要

A device for adjustment of the angular position of a shaft, preferably a camshaft of an internal combustion engine, relative to a driving wheel, comprising an adjusting device for adjustment of the angular position starting from a base position and comprising an arresting device for arresting the angular position in the base position is proposed. Between components (2, 3) capable of being respectively connected non-rotatably to the shaft and to the driving wheel, an interface (11) located eccentrically to the shaft and having a longitudinal extension running circumferentially of the shaft is provided. One part of the arresting device is formed as an arresting pin element (13) movable at an angle to the interface and the other part as an arresting recess (39) into which a portion of the arresting pin element (13) can engage when in the base position, the arresting pin element being mechanically preloaded in the engagement direction and being movable counter to the engagement direction by the pressure of a control fluid.
