Constructed plastic rotor with integrated cartridge and spring suspension
View Patent ↗A cover ( 4 ) for covering an axial side of a rotor core ( 6 ) that is arranged in a camshaft adjuster ( 50 ) and has a passage bore ( 28 ) for holding a locking pin ( 30 ) with which the rotor core ( 6 ) can be secured against rotation relative to a stator ( 54 ) of the camshaft adjuster ( 50 ). The specified cover includes a base body ( 8 ) for axially covering at least one area of the rotor core ( 6 ) with the passage bore ( 28 ) and a support element ( 38 ) that is arranged on the base body ( 8 ) for the axial counter support of the locking pin ( 30 ).
1. A cover for covering an axial side of a rotor core that is arranged in a camshaft adjuster, the rotor core includes a passage bore for holding a locking pin with which the rotor core can be secured against rotation relative to a stator of the camshaft adjuster, the cover comprising a base body for axial covering of at least one area of the rotor core with the passage bore, and a support element is arranged on the base body and axially extends from the base body for an axial counter support of the locking pin.
2. The cover according to claim 1 , comprising a ventilation channel with an opening in an area of the support element.
3. The cover according to claim 2 , wherein the ventilation channel is guided at least partially in the axial direction by the base body.
4. The cover according to claim 2 , wherein the ventilation channel is guided out from an opening in an area of the support element along a surface of the base body on which the support element is arranged.
5. The cover according to claim 1 , further comprising a cartridge that can be inserted concentrically in the passage bore and is held by the support element, the cartridge is provided for engagement in a recess on the locking pin.
6. The cover according to claim 1 , further comprising a suspension for a restoring element by which the locking pin is counter supported on the support element.
7. The cover according to claim 1 , further comprising a recess located in the base body that is arranged in a different location than the support element.
8. A rotor for a camshaft adjuster comprising a rotor core that has a hub for holding a camshaft and a passage bore guided through the hub for holding a locking pin with which the rotor core can be secured against rotation relative to a stator of the camshaft adjuster, and a cover according to claim 1 that is set axially on the rotor core, and the support element covers the passage bore of the hub in the axial direction.
9. The rotor according to claim 8 , comprising the locking pin held in the passage bore of the hub.
10. A camshaft adjuster comprising a stator for storing rotational energy from a crankshaft of an internal combustion engine and a rotor that is arranged so that it can rotate in the stator and that is constructed according to claim 8 for output of the rotational energy from the crankshaft to the camshaft.
