Abstract
A device for adjusting the angle of rotation between two rotating shafts, in particular a drive shaft of a reciprocating-piston internal combustion engine and a camshaft for actuating gas-exchange valves is provided, having a rotation element that is connected in a rotationally fixed manner to the drive shaft, a rotor that is connected in a rotationally fixed manner to the camshaft, and an angle of rotation adjustment system with a locking device which has at least one locking bolt, which is mounted movably in one of the components, and at least one corresponding opening in the other component. The locking bolt can be displaced into and out of the opening by a spring and/or hydraulic force.
Claims11
Device for adjusting an angle of rotation between first and second rotating shafts, the first shaft being a drive shaft and the second shaft being a camshaft of an internal combustion engine, the device comprising a rotation element, which is locked in rotation with the drive shaft, a rotor, which is locked in rotation with the camshaft, a device for adjusting the angle of rotation, and a locking device, which has at least one locking bolt mounted movably in one of the rotation element or the rotor and at least one corresponding opening in the other of the rotation element or the rotor, wherein the locking bolt can be displaced into and out of the opening by spring force hydraulic force, and a contact region of the locking bolt coming into active connection with the opening has an outwardly curved contour.
