Embodiment Construction

[0024] figure 1 Shows a camshaft adjuster 1 illustrating its various components. Camshaft adjuster for adjusting a camshaft 2 with respect to the (not shown) of the phase of the crankshaft. The camshaft adjuster 1 is used in the internal combustion engine in a motor vehicle powertrain. The camshaft adjuster 1 has a driven element 3. Driven element 3 may be connected to the camshaft 2 rotatably connected or coupled mode. The driven element 3 is designed / used to prepare the drive member relative to the camshaft adjuster 1 is 4 within a limited angular range (in order to adjust the phase) rotation. The driven element 3 is configured as a hub. 4 with a crankshaft drive element rotatably connected or coupled connections.

[0025] The camshaft adjuster 1 has a driven anchor 5. 5 follower shaft-like anchor member configured. Follower structure 5 i.e. the anchor axis. 5 follower anchoring element configured in particular as a hollow shaft. Follower anchoring element 5 is designed / int...

Abstract

The invention relates to a camshaft adjuster (1) for adjusting the phase of a camshaft (2), comprising a driven element (3), which is designed to rotate relative to a drive element (4) of the camshaft adjuster (1), and a shaft-like output anchor (5), which is intended to connect the driven element (3) to the camshaft (2) in a rotationally fixed manner, wherein the driven element (3) and the driven anchor (5) are connected to each other via a connecting part (6) having at least one first section (7) with a higher surface roughness and at least one second section (8) with a lower surface roughness, which adjoin each other in the circumferential direction. The invention further relates to a camshaft adjuster arrangement comprising the camshaft adjuster (1) and the camshaft (2) which is connected in a rotationally fixed manner to the driven anchor (5) by means of a surface-structured press-fit (14).

Description

Technical field [0001] The present invention relates to a camshaft adjuster for a motor vehicle powertrain modulating the phase of camshaft relative to the crankshaft. The present invention also relates to a camshaft adjuster means, the adjuster means camshaft having a camshaft adjuster and the camshaft is connected thereto. Background technique [0002] Camshaft adjuster is known in the prior art. For example, DE 10 2004 026 863 A1 discloses a method for adjusting and fixing the camshaft relative to its crankshaft of the engine phase of the camshaft adjuster, comprising: a driving wheel driven by the crankshaft; a driven member fixed to the camshaft the driven member disposed on the camshaft or camshafts driven by the drive wheel and the extended portion, wherein the driven member with respect to the phase of the driving wheel can be adjusted within a certain angular range, wherein the driven member secured in a force fit the extended portion of the camshaft or camshafts.
