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： In one embodiment, a sensor assembly has a magnetostrictive (MS) element and a sensor housing defining at least one active wall. A sensor channel is disposed on a first side of the active wall, with the MS element being disposed in the sensor channel and closely received therein. A fluid is on a second side of the active wall, and the active wall is the wall through which stress from pressure of the fluid causes stress on the MS element. The sensor channel defines an axis parallel to the active wall, and the MS element is positioned adjacent the active wall by sliding the MS element into an end of the sensor channel in a direction parallel to the active wall.

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 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.
