Problems solved by technology

[0006] However, it is problematic that the locking play may be defective due to the tolerance chain formed during the assembly of the camshaft phaser, so that a jamming of the locking pin and the locking disc during operation of the camshaft phaser is entirely possible.

Embodiment Construction

[0033] According to the prior art camshaft phase adjuster 1 (see figure 1 ) permits a change of the opening side and the closing side of the gas exchange valve of the internal combustion engine to be brought about during the operation of the internal combustion engine (not shown in detail).

[0034] For this purpose, the relative angular position of a camshaft (not shown in detail) of the internal combustion engine relative to a crankshaft (not shown in detail) of the internal combustion engine is continuously varied by means of a camshaft phaser 1 , the camshaft relative to the crank The shaft turns. By rotating the camshaft, the opening and closing times of the gas exchange valves are displaced in such a way that the internal combustion engine achieves its optimum performance at the corresponding rotational speed.

[0035]The camshaft phaser 1 has a cylindrical stator 2 which is connected in a rotationally fixed manner to a drive wheel of the camshaft, not shown in detail. ...

Abstract

The invention relates to an oscillating motor-type phaser (1) in which a locking device (1) is formed that comprises a spring-loaded locking bolt (23) and a locking disk (19) having a locking bore (26) for at least partially accommodating the locking bolt (23) in order to lock the stator (2) to the rotor (9) in an end position; the locking bolt (23) is accommodated in one of the blades (7'); when the blade (7') supporting the locking bolt (23) is locked to the adjacent link member (5), a locking play (31) providing mobility of the rotor (9) relative to the stator (2) is formed; the stator (2) is secured to the locking disk (19) using connecting elements (33). According to the invention, the locking disk (19) includes a stop element (32) in order to adjust the locked end position.

Description

technical field [0001] The invention relates to a camshaft phase adjuster for a camshaft according to the preamble of claim 1 . Background technique [0002] Camshaft phasers for camshafts of internal combustion engines are known. In a typical camshaft phasor, a controllably adjustable locking pin is slidably disposed in a hole in the rotor vane of the camshaft phasor so that under defined operating conditions of the phasor and motor Rotational blocking of the rotor relative to the stator is permitted. Known bolt locking mechanisms include a compression spring to tension the end of the bolt in a generally hardened position provided in the pulley or in the sprocket of the camshaft phaser so that the rotor is in relation to the pulley or chain. The stator to which the wheel is fixedly connected is locked. [0003] The rotor can be made of aluminum, for example, and the steel bushing is pressed in a defined axial position and inserted into the bore, so that the bolt can be g...
