摘要： A variable cam phaser has drive and driven members connected by helical splines of an annular phase control piston and a lash control piston, axial motion of which varies the angular phase relation between the drive and driven members. A single wave spring received in a groove in one of the pistons biases them apart to take up lash in the splines. A return spring biases the phase control piston to an initial phase setting. Pre-timing of the members is provided for by a driven (or drive) member comprising two components, a hub flange that supports the other member and a splined hub carried by and initially rotatable on a tubular protrusion of the hub flange. After assembly of the phasing mechanism, the hub is rotated on the hub flange to pre-time the initial phasing of the members. An end of the tubular protrusion is then deformed into a flange engaging an annular shoulder on the hub to lock the hub and hub flange members together and maintain the pre-timing. An annular cover is then installed and retained by a retaining ring to close a hydraulic pressure chamber and help support the members. Upon assembly to a camshaft, a center bolt clamps the cover, hub and hub flange to the camshaft and relieves the locking means from operational torque loads.

摘要： A die cast aluminum front cover plate for application in a vane-type camshaft phaser includes a plurality of bores and a plurality of steel threaded inserts press fitted into the bores. Steel threaded inserts add the required strength to the stator bolt threads to enable a shorter thread engagement, which in turn enables a thinner aluminum front cover plate that may be packaged in tight applications where prior art aluminum front covers cannot be used due to their larger thickness. The steel threaded inserts not only provide a higher stiffness but also have a flanged shape that effectively spreads the clamp load generated during the tightening of the stator bolts further out preventing local clamp load points and, consequently, reducing cover deflection over the span of the front cover plate.

摘要： A camshaft phaser controllably varies the phase relationship between a crankshaft and a camshaft in an internal combustion engine. The camshaft phaser includes an input member rotatable by the crankshaft. The input member is connected through a gear drive to an output member which is fixed to the camshaft. A rotational actuator acting on the gear drive unit causes relative rotation between the input member and the output member. A first stop member is rotatable with the input member in a one-to-one relationship. A second stop member is rotatable with the output member in a one-to-one relationship to limit relative angular travel between the input member and the output member. A torque absorption means is provided for limiting the rate at which torque is applied from the rotational actuator to the gear drive unit when the second stop member makes contact with the first stop member.

摘要： A torque bias coil spring for a camshaft phaser disposed in an annular well formed in the phaser rotor and having a central arbor for supporting the spring. The radius of the central arbor is such that the spring has radial operating clearance of 5-10%, as in the prior art. However, the improved arbor includes regions of higher radius at the arbor ends supporting the innermost and outermost coils of the spring. These regions serve to prevent the spring from being laterally displaced during torsional motion, thus minimizing the relative motion at the spring contact points, reducing stress on the spring, and improving the efficiency of the spring by reducing frictional hysteresis.
