摘要： A CVVL system including a self-locking helical gear pair with, optionally, a transmission to increase output torque of the actuator. The self-locking helical gear pair provides high forward efficiency and a fully mechanically self-locking feature. The actuator therefore requires a smaller motor to perform the same actuation as a prior art worm-gear system. The CVVL system comprises two helical gears having a radial pressure angle {acute over (α)} between 45° and 75° and a helix angle β between 60° and 80°. An asymmetric tooth profile is presently preferred, reducing contact stress and permitting higher torque density. Preferably, the helical gears are discontinuous and comprise laminated spur gear slices and hence are less costly to produce than continuous helical gears. Configurations are possible within the scope of the present invention include a single stage gear system; a multiple stage gear system; a planetary gear system; and an internal or external gear system.
摘要翻译：一种CVVL系统，包括一个自锁螺旋齿轮对，可选地是一个传动装置，以增加致动器的输出扭矩。自锁螺旋齿轮对提供高前向效率和全机械自锁功能。因此，致动器需要较小的电动机来执行与现有技术的蜗轮系统相同的致动。 CVVL系统包括两个螺旋齿轮，其具有45°至75°之间的径向压力角（锐角（α）}）和60°至80°之间的螺旋角β。目前优选不对称的齿形，减少接触应力并允许较高的扭矩密度。优选地，螺旋齿轮是不连续的，并且包括层压的正齿轮片，因此与连续的斜齿轮相比，制造成本更低。在本发明的范围内，构造是可能的，包括单级齿轮系统; 多级齿轮系统; 一个行星齿轮系统; 以及内部或外部齿轮系统。

摘要： A hybrid camshaft phaser comprising a conventional vane-type hydraulically-actuated phaser to which is coupled an electric motor and gear transmission. The transmission output shaft is coupled to the phaser rotor, optionally via an intermediate clutch mechanism. Under engine operating conditions in which the response of a hydraulic phaser is poor, the electric motor operates to augment the hydraulic actuation. Such conditions include at least low ambient temperatures at which oil viscosities are high, and high ambient temperatures and/or low engine speeds at which oil pressures are low. Preferably, at engine speeds above about 1500 rpm, the electric motor is de-energized.

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.
