摘要： A target wheel for a camshaft phaser stamped and drawn from sheet metal stock. The hub region of the target wheel may be drawn such that it extends through the phaser cover plate and seals directly against the face of the rotor, allowing a shorter cam bolt and resulting in reduction in mass and cost of the phaser. Alternatively, a separate hub is formed and then attached to a simplified stamped and drawn target wheel, or a target wheel hub is formed integrally with the rotor and extends through the cover plate to mate with a simplified stamped and drawn target wheel. Preferably, the hub is formed having a neck extending through a central opening in the target wheel, which neck is peened over during assembly to secure the wheel to the hub.

摘要： A target wheel/rotor pre-assembly for a camshaft phaser. A phaser rotor includes a central bore. A target wheel axial extension having a plurality of barbs is entered into the bore to fix the target wheel to the rotor, both axially and rotationally, prior to assembly of the rotor into a phaser stator during manufacture of the phaser. Simple gauge blocks or a fixture can be used to index the target wheel to the rotor such that all such rotor/wheel subassemblies are substantially identical, to a high degree of precision. Alternatively, the axial extension may be formed without barbs, the extension inserted into the rotor bore, and then the extension immobilized as by stamping of the barbs, tack welding, or the like. For another example, the axial extension may be formed as a separate intermediate barbed retainer that engages both the rotor bore and the target wheel.

摘要： In a first embodiment of a camshaft phaser, the rotor is split along an equatorial plane thereof, defining first and second rotor portions. A resilient seal is compressively disposed between the rotor portions to prevent leakage therebetween and to urge the rotor vanes against the cover plate and sprocket surfaces to prevent leakage around the vanes. Preferably, the seal includes radial seal elements to seal against the stator wall. Preferably, pressurized hydraulic fluid can enter between the first and second rotor portions and thereby assist the resilient seal in urging the rotor portions apart. In a second embodiment, the rotor is not split, and a resilient seal is provided on at least one axial face of the rotor vanes to seal the rotor vanes against the cover plate and sprocket surfaces.

摘要： A vane-type camshaft phaser includes a rotor having a plurality of vanes disposed in a stator having a plurality of lobes, the interspersion of vanes and lobes defining a plurality of alternating valve timing advance and valve timing retard chambers. Each vane and lobe tip is provided with an axially extending groove having an outward expansion of width. A wiper seal element, formed by stamping and folding from a single piece of sheet material, has folded wings that extend under compression into the groove. The spring loading of the wings against the tapered walls of the groove acts to urge the wiper seal element out of the groove and toward the opposing stator or rotor wall, thus ensuring a continuous forced sealing contact of the wiper seal element with the opposing wall and the groove walls during operation of the camshaft phaser.

摘要： In a prior art camshaft phaser having a biasing spring, the stator spring tang is anchored to a first binder screw passing through a stator lobe adjacent the locking pin-containing vane of the rotor, and the rotor spring tang is anchored to a first target wheel protrusion opposite such a vane. In an improved installation method in accordance with the invention, during assembly of an improved phaser the biasing spring is rotated about 180° from the prior art position such that the stator spring tang is anchored to a first fixed stop generally opposite the pin-containing vane, and the rotor spring tang is anchored to a second fixed stop generally adjacent such a vane.
