摘要： An electrical camshaft phaser arrangement for controllably varying the phase relationship between a crankshaft and a camshaft in an internal combustion engine includes an adjusting gear drive unit formed as a three shafts transmission having a drive shaft connected with the crankshaft, an output shaft connected with the camshaft, and an adjusting shaft connected with the control shaft of an electrical machine. The electrical machine allows phasing the camshaft with regards to the crankshaft by increasing or decreasing control shaft speed, the control shaft being spinning during phase holding modes. The adjusting gear drive unit is configured such that an energy recovering mode is provided wherein a braking torque is applied to the control shaft in order to generate electrical energy.

摘要： Improved stiffening and minimized distortion of a housing for an eVCP achieved by forming a plurality of radial housing stiffeners into the housing around the motor mount end and into the eVCP's hub. A back plate is press fit into the rear of the housing, and a straight axial knurl is applied to the surface of the back plate or housing, which knurl permits a larger tolerance-higher press fit class to be used without resulting in significant deformation of the housing. The knurled back plate is harder than the housing, causing the high points of the knurl to plastically deform or plow the housing material during assembly, resulting in less radial deformation of the bore and the journal bearing. An interface between the housing and the hub provides a journal bearing interface to improve axial stability between the hub and housing.

摘要： An eVCP camshaft phaser comprising a harmonic gear drive unit having a circular spline and a dynamic spline linked by a common flexspline, and a single wave generator disposed within the flexspline. The circular spline is connectable to either of a crankshaft-connectable sprocket or an engine camshaft, the dynamic spline being connectable to the other thereof. The wave generator is driven selectively by an eMotor to cause the dynamic spline to rotate past the circular spline, thereby changing the phase relationship between the crankshaft and the camshaft. A coaxial coil spring is connected to the sprocket and to the phaser hub and is positioned and tensioned to bias the phaser and camshaft to a stop position wherein the engine can run or be restarted after the eMotor is de-energized. Preferably, the spring comprises a spring cassette for easy assembly into the eVCP.
