    • 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.
    • 凸轮轴相位器可控地改变内燃机中的曲轴和凸轮轴之间的相位关系。 凸轮轴相位器包括可由曲轴旋转的输入构件。 输入构件通过齿轮传动连接到固定到凸轮轴的输出构件。 作用在齿轮驱动单元上的旋转致动器引起输入构件和输出构件之间的相对旋转。 第一止动构件可以与输入构件以一对一的关系旋转。 第二止动构件可与输出构件以一对一关系旋转,以限制输入构件和输出构件之间的相对角行程。 提供了一种扭矩吸收装置,用于当第二止挡件与第一止动件接触时,限制从旋转致动器向齿轮传动单元施加扭矩的速度。

    • A system for providing reliable, unalterable mechanical data associated with the mechanical properties of a concrete mass. The system includes a logger, a second memory device and an outbound data transfer device. The logger is provided with one or more sensors, a microprocessor and a first memory device. The one or more sensors measure physical properties of the concrete mass and generate data associated with the physical properties. The microprocessor receives the data from the sensor and calculates maturity data and mechanical strength data. The first memory device stores the mechanical strength data within the concrete mass in an unalterable form. The second memory device is located outside the concrete mass. The outbound data transfer device transfers the mechanical strength data from the first memory device to the second memory device.

    • 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.
    • 可变凸轮移相器具有通过环形相位控制活塞的螺旋花键和间隙控制活塞连接的驱动和驱动构件,其轴向运动改变了驱动构件和被驱动构件之间的角度相位关系。 接收在其中一个活塞中的凹槽中的单波形弹簧将它们分开偏压以在花键中卷起睫毛。 复位弹簧将相位控制活塞偏置到初始相位设置。 构件的预定时由包括两个部件的驱动(或驱动)构件提供,支撑另一个构件的轮毂凸缘和由轮毂凸缘的管状突起承载并最初可旋转的花键毂。 在相位机构的组装之后,轮毂在轮毂凸缘上旋转以预先准备构件的初始定相。 然后,管状突起的端部变形成与轮毂上的环形肩部接合的凸缘,以将轮毂和轮毂凸缘构件锁定在一起并保持预定时。 然后通过保持环安装并保持环形盖以关闭液压室并帮助支撑构件。 在组装到凸轮轴上时,中心螺栓将盖,轮毂和轮毂凸缘夹紧到凸轮轴,并且使锁定装置免于操作扭矩负载。
