Abstract
A hydraulic, vane-type camshaft adjuster (1) having a rotor (2) and a stator (3) mounted such as to be rotatable relative to each other and to form vanes, wherein, for the radial positioning of the rotor (2) relative to the stator (3), a return spring (5) is or can be secured at one end to the rotor (2) and at the other end to the stator (3), and a spring contact component (15), especially in the shape of a ring, for centering the return spring (5) and/or limiting the radial position thereof, is fixed to the rotor (2) in at least two points.
Claims18
A hydraulic camshaft adjuster comprising:
- a rotor;
- a stator mounted in such a way that the rotor and stator are rotatable relative to one another and form vane cells, a return spring for radially positioning the rotor relative to the stator being fixable to the rotor on the one hand and to the stator on the other hand, a spring contact component for centering the return spring or limiting a return spring radial position, the spring contact component being fixed to the rotor at two or more points by at least two fasteners, wherein a first end of the return spring engages with and/or encloses one of the at least two fasteners.
A hydraulic camshaft adjuster comprising:
- a rotor;
- a stator mounted in such a way that the rotor and stator are rotatable relative to one another and form vane cells, a return spring for radially positioning the rotor relative to the stator being fixable to the rotor on the one hand and to the stator on the other hand, a spring contact component for centering the return spring or limiting a return spring radial position being fixed to the rotor at two or more points,
- wherein the spring contact component includes at least one detent projection protruding radially into a central opening of the spring contact component, and a trigger wheel is situated on the hydraulic camshaft adjuster, passing through the central opening with a flange section, the at least one detent projection axially fixing the trigger wheel.
A hydraulic camshaft adjuster comprising:
- a rotor;
- a stator mounted in such a way that the rotor and stator are rotatable relative to one another and form vane cells, a return spring for radially positioning the rotor relative to the stator being fixable to the rotor on the one hand and to the stator on the other hand, a spring contact component for centering the return spring or limiting a return spring radial position, the spring contact component being fixed to the rotor at two or more points by at least two fasteners,
- wherein the spring contact component includes projections which protrude from a plane of the spring contact component in a same axial direction, the projections each corresponding to a position of one of the at least two fasteners.
