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 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.
摘要翻译：用于叶片式凸轮轴相移器的压铸铝前盖板包括多个孔和多个压制在孔中的钢螺纹刀片。钢螺纹插入件为定子螺栓螺纹增加了所需的强度，以实现较短的螺纹接合，从而使更薄的铝前盖板可以在紧密的应用中被包装，其中现有技术的铝前盖由于其较大的厚度而不能使用。钢螺纹插入件不仅提供更高的刚度，而且还具有凸缘形状，其有效地扩展在定子螺栓紧固期间产生的夹紧负载，进一步防止局部夹紧负载点，并因此减小前部跨度上的盖挠曲盖盘。

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： An electromechanical camshaft phasing system comprising a first pinion gear mounted on the end of an engine camshaft and engaged by a worm gear mounted on a transverse shaft extending from and journalled by bearings in a phaser drive sprocket to cause the camshaft to rotate in response to the engine crankshaft. The first pinion gear is surrounded by a ring gear having a hub keyed to an armature or stator shaft of a motor mounted on the engine coaxially of the camshaft and first pinion gear. A second pinion gear mounted on the worm gear shaft engages the ring gear such that motor rotation of the ring gear about the first pinion gear causes rotation of the second pinion gear, worm gear, first pinion gear, and thus the camshaft with respect to the sprocket, thus varying the phase of the camshaft with respect to the crankshaft.

摘要： A self-contained lash adjuster includes a closed end cylinder body and a plunger in the cylinder defining a pressure chamber at the closed end of the cylinder and an internal reservoir connected with the chamber by a one-way passage in the plunger. A diaphragm sealing the reservoir is loaded by a spring piston to pressurize the reservoir and apply a differential pressure extending force to the plunger. The plunger is preferably made in two parts with the diaphragm in the lower part defining the chamber and the piston in the upper part distal from the chamber. The two-part construction permits leakdown testing before permanent installation of the diaphragm. A seal in the lower part beyond a return port seals the plunger walls to the cylinder. Installation during assembly of excess fluid for make-up is controlled by positioning of the plunger lower part during filling in a hyper extended position beyond the fully extended position to which the plunger is limited after full assembly of the lash adjuster.

摘要： A vane-type camshaft phaser having a rotational authority between 40 crank degrees before TDC and 30 crank degrees after TDC. The phaser includes a stator seat formed at a rotation position intermediate between full advance and full retard. A locking pin in a vane of the rotor engages the seat, locking the rotor at the intermediate position. The pin is disengaged by pressurized engine oil independent of oil flows for advance and retard of the rotor. The oil is controlled by a dedicated valve. Preferably, the seat and the ends of the locking pin are vented by passages in the rotor and stator which are aligned when the rotor is at the selected locking angle to remove oil resistance to entry of the pin into the seat. To position the locking pin over the seat, phasing rate is reduced to allow time for the locking pin to engage the seat.
