    Abstract: A detent assembly and a method of assembling the detent assembly are disclosed. The detent assembly includes a first shaft rotatable about a longitudinal axis and has an outer surface. The first shaft defines a cavity having an opening defined by the outer surface. The detent assembly further includes a camshaft defining an aperture along the longitudinal axis to present an inner wall of the camshaft that circumscribes the longitudinal axis. The inner wall defines a plurality of recesses spaced from each other. The detent assembly also includes a self-contained plunger unit that is secured to the first shaft in the cavity as a unit. A plunger of the self-contained plunger unit engages the inner wall as the camshaft is disposed over the self-contained plunger unit so that the plunger rests in one of the recesses of the camshaft to selectively secure together the first shaft and the camshaft.

    Abstract: A camshaft assembly includes a camshaft rotatable about a cam axis, and a lobe pack slideably attached to the camshaft. The lobe pack includes a barrel cam that defines a control groove disposed annularly about the cam axis. When the camshaft and the lobe pack rotate about the cam axis in a first rotational direction, the control groove is shaped to react against either a first or second shifting pin, to guide the lobe pack along a first or third path respectively, into a first or second axial position respectively. When the camshaft and the lobe pack rotate about the cam axis in a second rotational direction, the control groove is shaped to react against the first and second shifting pins to guide the lobe pack along a second path, into the second axial position.

    Abstract: A camshaft assembly can control the motion of the intake or exhaust valves of an internal combustion engine and includes a base shaft extending along a longitudinal axis. The camshaft assembly further includes an axially movable structure mounted on the base shaft and axially movable relative to the base shaft. The axially movable structure includes a plurality of lobe packs. Each lobe pack includes a plurality of cam lobes. The axially movable structure includes a barrel cam defining a control groove. The camshaft assembly additionally includes an actuator including an actuator body and a pin movably coupled to the actuator body between a retracted position and an extended position. The axially movable structure can move axially relative to the base shaft when the base shaft rotates about the longitudinal axis and the pin is in the extended position and at least partially disposed in the control groove.

    Abstract: A camshaft assembly includes an actuator and an axially moveable structure mounted to a base shaft wherein the axially moveable structure includes a plurality of lobe packs and a cam barrel. The axially movable structure moves along the base shaft in the axial direction along a longitudinal axis of the base shaft, but is rotationally fixed to the base shaft. The barrel cam includes an inner wall and an outer wall which defines a control groove therebetween. The control groove further defines first and second regions wherein the first region includes a fixed narrow control groove width and the second region includes a progressively decreasing control groove width. The actuator shifts the axially moveable structure relative to the base shaft between a first position and a second position. A recess is defined in the outer wall such that the recess is disposed adjacent to the first region.

    Abstract: A camshaft assembly for a vehicle engine includes a camshaft member, a cam phaser and a cam nose. The camshaft member includes a front end and a rear end. The camshaft member may be configured to actuate at least one intake valve of a combustion chamber. The cam phaser affixed to the front end of the camshaft member while the cam nose may be disposed at the front end of the camshaft. The cam nose further includes a cam nose face with a curvilinear groove surrounding a central axis region of the cam nose. The curvilinear groove may be configured to engage with the cam phaser to prevent oil leakage out from the central axis region and/or to rotationally lock the cam phaser to the camshaft member.
