Abstract: A camshaft phaser is provided for controllably varying the phaser relationship between a crankshaft and a camshaft in an internal combustion engine which includes a camshaft bearing for supporting the camshaft and which defines a mounting bore for mounting the camshaft phaser to the internal combustion engine. The camshaft phaser includes a housing with a gear drive unit disposed within the housing. The gear drive unit includes an input gear member and an output gear member such that the input gear member is attachable to the crankshaft and such that the input gear member is attached to an output shaft of an electric motor. The output gear member is attachable to the camshaft such that rotation of the input gear member by the electric motor causes relative rotation between the crankshaft and the camshaft. The camshaft phaser is disposed between the mounting bore and the camshaft bearing.

Abstract: An internal combustion engine includes a crankshaft rotatable about a crankshaft axis; a camshaft rotatable by the crankshaft about a camshaft axis; an engine cover defining an engine cover volume within the internal combustion engine; a drive member disposed within the engine cover volume which transfers rotational motion from the crankshaft to the camshaft; a camshaft phaser disposed within the engine cover volume which controllably varies the phase relationship between the crankshaft and the camshaft; an actuator which operates the camshaft phaser; and an actuator mount within the engine cover volume which mounts the actuator structurally independent of the engine cover, thereby allowing removal of the engine cover independently of the actuator.

Abstract: A camshaft phaser for controllably varying the phase relationship between a crankshaft and a camshaft of an internal combustion engine includes a housing connectable to the crankshaft and having a housing bore extending therethrough along an axis. A back cover is attached to one axial end of the housing while a front cover is attached to the other axial end of the housing. An output hub connectable to the camshaft is disposed coaxially within the housing and captured axially between the back cover and the front cover. A harmonic gear drive unit is disposed operationally between the housing and the output hub and is connected to a rotational actuator for imparting rotation on the harmonic gear drive unit such that rotation of the harmonic gear drive unit by the rotational actuator causes relative rotation between the housing and the output hub.

Abstract: A camshaft phaser includes a housing having a housing bore extending along an axis and a plurality of lobes extending radially inward. The camshaft phaser also includes a stroke limiter having a central hub with a plurality of vanes extending radially outward such that the vanes are interspersed with lobes. The camshaft phaser also includes a harmonic gear drive unit disposed operationally between the housing and the stroke limiter, the harmonic gear drive unit being connected to a rotational actuator for imparting rotation on the harmonic gear drive unit such that rotation of the harmonic gear drive unit by the rotational actuator causes relative rotation between the housing and the stroke limiter. The amount of relative rotation between the housing and the stroke limiter is limited by at least one of the plurality of lobes and at least one of the plurality of vanes.

Abstract: An internal combustion includes a crankshaft and a camshaft rotatable by the crankshaft. The internal combustion engine also includes an oil source, an engine cover, and a drive member disposed within the engine cover for transferring rotational motion from the crankshaft to the camshaft. A camshaft phaser actuated by an electric motor is disposed within the engine cover for controllably varying the phase relationship between the crankshaft and the camshaft. A supply passage communicates oil from the oil source to the camshaft phaser in order to lubricate the camshaft phaser and a drain passage drains oil from the camshaft phaser to the oil source. A sealing arrangement defines a dry zone within the engine cover to isolate the drive member from oil used to lubricate the camshaft phaser.
