Abstract
The disclosure relates to an electromagnetic actuating device for a hydraulic camshaft adjuster. The electronic actuating device includes a housing, a yoke, a pole core, an armature, and an actuating pin and a bearing unit. The actuating pin is led out of the housing by means of the bearing unit, and the bearing unit forms a press-fit connection with the housing or with a component connected to the housing. To improve the connection, the bearing unit, the housing and/or the component connected to the housing have a recess that increases the elasticity of the press-fit connection.
Claims8
An electromagnetic actuating device for a hydraulic camshaft adjuster, comprising:
- a housing
- a yoke,
- a pole core,
- an armature,
- an actuating pin, and
- a bearing unit;
- the actuating pin is led out of the housing via the bearing unit, and;
- a first round surface of the bearing unit forms a press-fit connection with a second round surface of one of the housing or with a component connected to the housing,
- wherein a recess is arranged on the first round surface of the bearing unit so as to increase an elasticity of the press-fit connection, the recess extending radially inwardly from the first round surface.
An electromagnetic actuating device for a hydraulic camshaft adjuster, comprising:
- a housing,
- a coil disposed within the housing,
- an armature disposed within the coil,
- a bearing unit disposed within an end of the housing via a press-fit connection,
- an actuating pin:
- configured to be axially actuated by the armature,
- disposed within and slidably guided by the bearing unit,
- extending outside of the housing from the bearing unit,
- wherein the press-fit connection:
- is defined by a first round surface of the bearing unit and a second round surface of one of the housing or a separate component attached to the housing, and
- the first round surface includes circumferentially arranged recesses that extend radially inwardly from the first round surface, the circumferentially arranged recesses configured to increase an elasticity of the press-fit connection.
