  • Patent number: 8176886
    Abstract: A camshaft adjusting device for an internal combustion engine of a motor vehicle. The camshaft adjusting device has a stator which is driven via a crankshaft of the internal combustion engine and a rotor which is connected in a rotationally fixed manner to the camshaft. The rotary angle position of the rotor can be varied with respect to the stator by way of a piston which can be displaced in the radial direction.

  • Publication number: 20110041789
    Abstract: A device for adjusting the rotational position of a camshaft relative to a crankshaft of an internal combustion engine having a rotor (1), which is connected rotationally fixed to the camshaft, and a stator (2), which is driven by the crankshaft. The rotor (1) or the stator (2) has a hole (10), in which a fixing unit (3) is disposed for fixing a target position of the rotor (1) to the stator (2), which engages so it can be detached in a locking link (5) disposed on the other part. The position of the fixing unit (3) can be set in the longitudinal direction of the hole (10) and the hole (10) is disposed at an acute angle (F) to the adjustment direction (G) of the rotor (1) relative to the stator (2).

  • Patent number: 7597076
    Abstract: A device for changing the control times of an internal combustion engine (camshaft adjuster) having a pressure medium distributor arranged within a camshaft is provided. The pressure medium distributor is provided at its front end with a radially extending shoulder, this shoulder forming part of the camshaft axial mounting.

  • Patent number: 7475660
    Abstract: An internal-combustion engine with a device for adjusting the rotational angle (camshaft adjuster (1)) of a camshaft (2) relative to a crankshaft is provided. The device comprises a driving wheel (3) connected in a rotationally locked way to the crankshaft, a driven part (6) connected in a rotationally locked way to the camshaft (2), and an adjusting mechanism, with which the phase position between the crankshaft and camshaft (2) can be set and maintained in a certain range of angles. A reduction of the required axial structural space of the camshaft adjuster (1) and the number of individual parts is achieved in that the driven part (6) is fixed to the camshaft (2) with a frictional, positive-fit, or interference-fit connection.
