TRAPPED SUPPORT PIN FOR SPIRAL SPRING RETENTION IN A CAMSHAFT PHASER

摘要

A camshaft phaser, including: an axis of rotation; a drive sprocket arranged to receive torque; a stator non-rotatably connected to the drive sprocket; a rotor at least partially rotatable with respect to the stator, arranged to non-rotatably connect to a camshaft and including first and second radially disposed sides facing, respectively, in first and second opposite axial directions parallel to the axis of rotation, a through-bore connecting the first and second radially disposed sides, and a support pin including a first portion disposed in the through-bore and a second portion extending past the second radially disposed side in the second axial direction; and a positioning spring engaged with the second portion and the stator to urge the rotor in a circumferential direction, wherein a line parallel to the axis of rotation passes through the first portion and material forming the rotor.
