    • A non-synchronous camshaft phasing device 46 for use with an internal combustion engine E. The internal combustion engine E includes an engine control unit ECU, a camshaft 42 and a crankshaft 12. The non-synchronous phasing device 46 is located between the crankshaft 12 and the camshaft 42 for controlling a phase shift angle between the camshaft 42 and the crankshaft 12. The phasing device 46 comprises an input shaft 36 coupled to the crankshaft 12 via a non-synchronous belt 40. The phasing device 46 also comprises an output shaft 42 coupled to the camshaft 44; a planetary gear train 48 co-axially aligned around and coupled with the input shaft 36 and the output shaft 42; and an motor 50 coupled to the planetary gear train 48 by a carrier 56. A controller operatively connects to the engine control unit ECU, wherein the controller is configured to receive engine operating signals generated by the engine control unit ECU and to receive signals from position sensors 51 coupled to the input shaft 36 and to the output shaft 42. In response to the signals, the controller generates and sends a torque command signal to the motor 50 to command the motor 50 to control the planetary gear train 48 through the carrier 56 to adjust the phase shift angle between the camshaft and the crankshaft 12.
    • 一种与内燃机E一起使用的非同步凸轮轴相位装置46.内燃机E包括发动机控制单元ECU,凸轮轴42和曲轴12.非同步定相装置46位于曲轴12 以及用于控制凸轮轴42和曲轴12之间的相移角的凸轮轴42.定相装置46包括通过非同步带40联接到曲轴12的输入轴36。定相装置46还包括输出轴 42连接到凸轮轴44; 行星齿轮系48与输入轴36和输出轴42同轴地对准并联接; 以及通过载体56联接到行星齿轮系48的马达50.控制器可操作地连接到发动机控制单元ECU,其中控制器被配置为接收由发动机控制单元ECU产生的发动机操作信号并从位置接收信号 耦合到输入轴36和输出轴42的传感器51.响应于该信号,控制器产生并向马达50发送扭矩指令信号,以命令马达50通过载体56来控制行星齿轮系48 以调节凸轮轴和曲轴12之间的相移角。
