    摘要: A camshaft phaser includes a housing with a harmonic gear drive unit disposed therein. The harmonic gear drive unit includes a circular spline and a dynamic spline, a flexspline disposed radially within the circular spline and the dynamic spline, a wave generator disposed radially within the flexspline, and a rotational actuator connectable to the wave generator. One of the circular spline and the dynamic spline is fixed to the housing. A hub is rotatably disposed radially within the housing and attachable to the camshaft and fixed to the other of the circular spline and the dynamic spline. A first arcuate input stop member is rotatable with one of the circular spline and the dynamic spline and is received within a first arcuate output opening defined by at least a first arcuate output stop member rotatable with the other of the circular spline and the dynamic spline.

    摘要: A camshaft phaser includes a housing with a harmonic gear drive unit disposed therein. The harmonic gear drive unit includes a circular spline and a dynamic spline, a flexspline disposed within the circular spline and the dynamic spline, a wave generator disposed within the flexspline, and a rotational actuator connectable to the wave generator. A coupling adapter is disposed coaxially within the housing bore and fixed to the wave generator and supported in the housing by a bearing which is press fit onto a bearing surface of the coupling adapter. The coupling adapter has a coupling adapter bore with opposing drive lugs extending radially inward therefrom which are axially coincident with the bearing surface. A coupling of the rotational actuator is disposed within the coupling adapter bore and has opposing drive slots which receive the opposing drive lugs, thereby transmitting motion from the coupling to the coupling adapter.

    摘要: A valve train for an internal combustion engine includes a camshaft and a variable cam phaser connected to the camshaft for driving the camshaft. The variable cam phaser includes an input shaft rotationally coupled to a crankshaft drive member; and an output shaft rotationally coupled to the camshaft and coaxial with the input shaft. Electrically operated adjusting means drivingly connect the input and output shafts enabling the input and output shafts to be selectively, angularly adjusted while maintaining driving engagement therebetween. The input and output shafts are coupled to the drive member and camshaft via respective, rotationally stiff, flexible couplings.

    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.
