A device (1) which is used to modify the control times of an internal combustion engine (100) is provided. The device (1) includes a drive wheel (13), a drive element (4) and a swashplate mechanism (4). The torque of the crankshaft (101) is transferred via a primary drive to the drive wheel (13) and then, via the swashplate mechanism (2) to the drive element (4) which is secured to the camshaft (11) in a rotationally fixed manner. The configuration of the mounting of the drive wheel (13) on the tooth support (9) of the drive element (4) reduces the axial area of the device (1) due to the construction measures. The invention also relates to an embodiment, wherein the device (1) is fixed to the camshaft (11) by means of a securing screw (12a) without the need for additional space.
Device for modifying the control times of gas-exchange valves of an internal combustion engine with comprising a drive wheel in driven connection with a crankshaft and with a swashplate gear mechanism, which has a housing and a driven element in driving connection with a camshaft, a radial outer ring section of the driven element is constructed as a teeth carrier, a toothed ring is formed on an axial side surface of the teeth carrier and a drive wheel or the housing is supported on the driven element so that it can rotate relative to the driven element, an outer casing surface of the teeth carrier is used as a radial bearing surface for the housing or the drive wheel.
Device for modifying the control times of gas-exchange valves of an internal combustion engine comprising a swashplate gear mechanism including at least one swashplate, which is supported on an adjustment shaft, the adjustment shaft is supported on a hollow shaft, the hollow shaft is locked in rotation with the camshaft by an attachment screw, and a radially inwardly extending collar, on which a screw head of the attachment screw is supported, is formed on an inner casing surface of the hollow shaft.
