Abstract
This disclosure relates to a trigger wheel for a camshaft adjuster, having a side wall extending along a central longitudinal axis, wherein a formed feature made to project in a radial direction of the longitudinal axis is formed in a circumferential region of the side wall. The formed feature is provided at least in part with a wave profile. Moreover, the disclosure relates to a camshaft adjuster having this trigger wheel.
Claims16
A camshaft adjuster configured for an internal combustion engine, the camshaft adjuster comprising:
- a stator,
- a rotor rotatable relative to the stator, and
- a trigger wheel having:
- a rotational axis, and
- a side wall extending along the rotational axis, the side wall having a tab formed with a wave profile, the tab cut from the side wall forming two opposite axial sides of the tab so that each axial side of the tab is separated from the side wall, and a first end of the tab and a second end of the tab are formed integrally with the side wall.
A camshaft adjuster configured for an internal combustion engine, the camshaft adjuster comprising:
- a stator,
- a rotor rotatable relative to the stator, and
- a trigger wheel having:
- a rotational axis,
- a disk region that extends radially from the rotational axis, the disk region merging into a side wall, the side wall extending from a radially inner portion of the disk along the rotational axis, and
- at least one protrusion, a first portion of the at least one protrusion projecting radially outward from a circumferential region of the side wall, a second portion of the at least one protrusion forming a tab, the tab cut and separated from the at least one protrusion or the side wall on two opposite axial sides, and a first end of the tab and a second end of the tab are formed integrally with the side wall.
