摘要： A strain sensor includes a load carrying body configured to strain in response to a load applied along a load path. The sensor further includes a magnetostrictive electrical conductor affixed to the body but out of the load path. Application of the load causes the body to strain, which in turn results in a proportional stress being imparted to the magnetostrictive conductor, altering its magnetic permeability. A circuit is electrically connected to the conductor to detect such changes in permeability, which are indicative of the applied load.

摘要： A camshaft phaser comprising first and second harmonic gear drive (HD) units disposed in back-to-back relationship. Each HD includes an elliptical wave generator (WG), a flexspline (FS) deformable by the WG, and a circular spline (CS) for engaging the FS. A dynamic spline (DS) connects the first and second FSs. The first HD is an input HD driven by an engine crankshaft via a sprocket wheel connected to the input CS. The second HD is an output HD driving an engine camshaft. The DS is meshed with both the input FS and the output FS. The phase relationship between the crankshaft and the camshaft may be changed by changing the angular relationship between the first and second WGs. Such change is effected by holding the first WG stationary and varying the angular position of the second WG via an electric motor.

摘要： A camshaft phaser comprising a differential bevel gear arrangement to vary the phase relationship of a camshaft to a crankshaft in an internal combustion engine. In the differential gear system, a 45° beveled input gear is mounted parallel to and coaxial with a 45° beveled output gear. One or more 45° beveled spider gears is disposed in meshed relationship with the input and output gears in a gear pattern having a rectangular cross-sectional appearance. Rotation of the input gear causes an opposite rotation of the output gear. The phase relationship between the input and output gears may be varied by varying the position of the spider gear. The input gear and spider gears may be driven via a sprocket in time with the crankshaft in a plurality of arrangements.

摘要： A vane-type camshaft phaser includes a vaned camshaft rotor disposed within a lobed stator, defining phase advance and retard chambers filled with oil. The height of the rotor is less than the height of the stator, providing space for a vaned brake rotor alongside the camshaft rotor. The brake rotor is free to rotate independently of the camshaft rotor. The volume of each advance and retard chamber is a function of the rotational position of both the camshaft rotor and the brake rotor, and the volume of each chamber is constant. Rotation of the brake rotor in one direction causes rotation of the camshaft rotor in the opposite direction. The brake rotor is connected to a controllable brake mechanism. By sensing of the camshaft rotor position and feedback control of the braking mechanism, the camshaft rotor may be maintained at any position.

摘要： A mechanically-actuated camshaft phaser for varying the phase of a camshaft in an internal combustion engine. The phaser comprises two colinear helical mechanisms having opposite-handed helices engaging a common nut for common rotation. One helical mechanism is operatively attached to a sprocket or pulley in time with an engine crankshaft. The other helical mechanism is operatively attached to an engine camshaft. A motive system drives the nut axially of itself along the helical mechanisms, causing a phase shift between the mechanisms and hence between the crankshaft and the camshaft. The preferred helical mechanisms are ball screws, and the preferred motive system is a worm gear driven by a worm on the shaft of an electric motor.
