Camshaft adjuster
View Patent ↗A camshaft adjuster ( 1 ) has a plurality of locking mechanisms ( 5 ) arranged on different pitch circles concentrically with respect to the axis of rotation ( 7 ) of the camshaft adjuster ( 1 ).
1. A camshaft adjuster comprising:
a driving element;
an output element, the driving element and the output element having multiple vanes, the vanes of the driving element and the output element sectioning off oppositely acting working chambers, the working chambers pressurizable with a hydraulic medium for the purpose of achieving a relative rotation between the driving element and the output element; and
multiple locks for blocking or unblocking the relative rotation between the driving element and the output element, each lock having a locking axis, the lock being locked or unlocked in the direction of the locking axis, the locking axes of the locks having distances to a rotation axis of the camshaft adjuster different from each other; wherein the locking axes are situated in parallel to the rotation axis of the camshaft adjuster, the multiple locks being arranged in one of the driving element and the output element.
2. The camshaft adjuster as recited in claim 1 wherein the locks are rotationally symmetrical.
3. The camshaft adjuster as recited in claim 1 wherein the locks each have one locking pin and one locking spring.
4. The camshaft adjuster as recited in claim 1 wherein, in a locked state, one lock defines a relative angular position of the driving element to the output element, in which the vanes sectioning off one of the working chambers are spaced a distance apart.
5. The camshaft adjuster as recited in claim 1 wherein, in their locked states, multiple locks together define a relative angular position of the driving element to the output element, in which the vanes sectioning off one of the working chambers are spaced a distance apart.
6. The camshaft adjuster as recited in claim 1 further comprising locking gates associated with the locks on different components of the camshaft adjuster.
7. The camshaft adjuster as recited in claim 1 further comprising locking gates associated with the locks on a same component of the camshaft adjuster.
8. The camshaft adjuster as recited in claim 7 wherein the same component is a side cover or the driving element of the camshaft adjuster.
9. The camshaft adjuster as recited in claim 1 wherein one lock is situated within a vane and another lock is situated outside of the vane or another vane.
10. The camshaft adjuster as recited in claim 1 wherein the multiple locks are arranged in the output element.
