  • FIGS. 1-6 illustrate a unitized valve train assembly 10 including a rocker arm or a spherical-end pivoting, roller cam follower assembly or roller finger follower 14 , a hydraulic lash adjuster (“HLA”) 18 , and a coupling device 22 for unitizing or coupling the follower 14 and the HLA 18 .
  • the follower 14 includes a ball socket having a pocket 24 in which the spherical-pivot component of the HLA, customarily the piston or plunger 26 , is received.
  • a similar follower 14 is shown in published PCT Patent Application No. WO 2008/002746, the entire content of which is incorporated herein by reference.
  • the HLA 18 includes a housing or body 30 in which the plunger 26 is supported, and the plunger 26 includes a shank 34 and a spherical end portion 38 which engages the pocket 24 of the follower 14 (see FIG. 19 ).
  • a unitized valve train assembly 10 may be used, for example, in an engine having an overhead camshaft configuration.
  • FIGS. 1-3 illustrate a cam lobe 42 of an overhead camshaft actuating the follower 14 and a corresponding valve 46 .
  • the body 30 of the HLA 18 includes a cap 50 crimped to the upper portion of the body 30 , thereby forming an integrated part of the body 30 .
  • the cap 50 axially secures the plunger 26 within the body 30 and limits the axial extent to which the plunger 26 can extend from the body 30 .
  • the plunger 26 of the HLA 18 is configured with an undercut 54 , a portion of which is defined by the shank 34 .
  • the plunger 26 of the HLA 18 may be configured without an undercut. Such a plunger without an undercut is shown and described in published PCT Patent Application No. WO 2008/002746.
  • the coupling device 22 is comprised of a clip 58 made from a single piece of resilient material (e.g., steel wire) that is bent or otherwise formed into the illustrated shape.
  • the steel wire utilized to form the clip 58 has a diameter between about 0.5 and about 0.75 mm.
  • other wire diameters may be utilized depending on the sizing of the other valve train components.
  • the wire diameter utilized to form the clip 58 also affects the positional tolerance where the clip 58 may be attached to the plunger shank 34 .
  • the clip 58 should be secured to the plunger shank 34 in an axial position on the plunger shank 34 in which no portion of the clip 58 substantially interferes with movement of the plunger 26 or the follower 14 during operation of the engine. As such, decreasing the wire diameter of the clip 58 proportionally increases the positional tolerance where the clip 58 may be attached to the plunger shank 34 .
  • the clip 58 includes a first or upper arm 62 selectively engageable with the follower 14 , a second or lower arm 66 configured to engage and clamp onto the plunger 26 , and an intermediate portion 70 interconnecting the upper and lower arms 62 , 66 .
  • the upper arm 62 of the clip 58 is configured to extend around the ball socket of the follower 14 (see FIGS. 1 and 2 ).
  • the upper arm 62 includes an arcuate lip portion 74 engageable with the ball socket of the follower 14 to facilitate the connection of the clip 58 and the follower 14 , and to provide resistance to the disconnection of the clip 58 and the follower 14 .
  • the lower arm 66 of the clip 58 includes a semi-circular portion or a hook portion 78 having opposite ends 82 a , 82 b and a splayed end portion 86 disposed toward the distal end of the hook portion 78 .
  • the hook portion 78 of the clip 58 includes an inner diameter D 1 less than the outer diameter D 2 of the plunger shank 34 (see FIG. 19 ), resulting in an interference fit between the clip 58 and the plunger shank 34 when the hook portion 78 of the clip 58 is engaged or clamped to the plunger shank 34 .
  • the interference between the inner diameter D 1 of the hook portion 78 and the outer diameter D 2 of the plunger shank 34 may be between about 1% and about 8% of the outer diameter D 2 of the plunger shank 34 .
  • the inner diameter D 1 of the hook portion 78 may be between about 92% and about 99% of the outer diameter D 2 of the plunger shank 34 .
  • the interference between the inner diameter D 1 of the hook portion 78 and the outer diameter D 2 of the plunger shank 34 may be about 4% of the outer diameter D 2 of the plunger shank 34 .
  • the respective ends 82 a , 82 b of the hook portion 78 when the clip 58 is removed from the plunger shank 34 and when the clip 58 is in its undeformed or undeflected state, may be spaced by a length or gap dimension D 3 less than the outer diameter D 2 of the plunger shank 34 .
  • the gap dimension D 3 may be between about 5% and about 13% less than the outer diameter D 2 of the plunger shank 34 when the clip 58 is removed from the plunger shank 34 and when the clip 58 is in its undeformed or undeflected state.
  • FIGS. 1-6 illustrate the clip 58 attached to the HLA 18 .
  • the hook portion 78 is axially aligned with the plunger 26 and the clip 58 is moved toward the plunger 26 in a direction substantially transverse to a central axis 90 of the plunger 26 (see FIG. 19 ).
  • the hook portion 78 snaps onto the plunger shank 34 to secure the clip 58 to the plunger 26 .
  • the gap dimension D 3 between the respective ends 82 a , 82 b of the hook portion 78 is greater than the gap dimension D 3 when the clip 58 is removed from the plunger shank 34 .
  • the gap dimension D 3 between the respective ends 82 a , 82 b of the hook portion 78 after the clip 58 is engaged to the plunger shank 34 is about 2% to about 5% less than the outer diameter D 2 of the plunger shank 34 . Because the hook portion 78 of the clip 58 cannot fully return to its undeformed or undeflected state shown in FIGS.
  • a clamping force is exerted on the plunger shank 34 by the hook portion 78 sufficient to generate frictional forces on the plunger shank 34 along and about the central axis 90 of the plunger 26 to substantially prevent the hook portion 78 from rotating, pivoting, or rocking with respect to the plunger shank 34 during operation of the engine.
  • the clip 58 may co-rotate with the plunger 26 with respect to the plunger body 30 and the follower 14 .
  • the intermediate portion 70 of the clip 58 may come into contact with a side wall of the follower 14 should the plunger 26 and the clip 58 co-rotate about the central axis 90 during operation of the engine.
  • the side walls of the follower 14 limit the extent to which the plunger 26 and the clip 58 may co-rotate during operation of the engine.
  • the unitized clip 58 and HLA 18 may be assembled onto the follower 14 in substantially the same fashion as disclosed in published PCT Patent Application No. WO 2008/002746.
  • the follower 14 may initially be oriented such that its pocket 24 may receive the spherical end portion 38 of the plunger 26 .
  • the arcuate lip portion 74 of the upper arm 62 may engage an upper surface of the follower 14 , causing the clip 58 to deflect or elastically bend to an “open” position to complete the insertion of the spherical end portion 38 of the plunger 26 in the pocket 24 of the follower 14 .
  • the clip 58 will resume its undeflected shape or its “closed” position to secure the follower 14 to the HLA 18 , as shown in FIGS. 1-6 .
  • the follower 14 and the HLA 18 may be pre-assembled by positioning the spherical end portion 38 of the plunger 26 into the pocket 24 of the follower 14 , and the clip 58 may be brought in from the side of the pre-assembled follower 14 and HLA 18 , in a direction substantially transverse to the central axis 90 of the plunger 26 , to engage the hook portion 78 of the clip 58 and the plunger shank 34 .
  • the upper arm 62 may or may not be deflected to clear the side wall of the follower 14 upon attachment of the clip 58 in this manner.
  • the follower 14 and HLA 18 can now be handled as a unit, without substantial concern that the HLA 18 may be unintentionally separated from the follower 14 .
  • the arcuate lip portion 74 must be forced to pass over the upper surface of the follower 14 , thereby causing the clip 58 to deflect back to its “open” position to allow removal of the spherical end portion 38 of the plunger 26 from the pocket 24 .
  • the resilient property of the clip 58 allows it to be bent slightly to permit insertion and removal of the follower 14 between the upper arm 62 of the clip 58 and the spherical end portion 38 of the plunger 26 without permanently distorting the clip 58 to the extent that its retention is substantially compromised.
  • the arm 66 is positioned on the plunger shank 34 such that it is spaced, in a direction parallel to the longitudinal axis 90 , from a bottom surface of the follower 14 , and particularly a peripheral surface 92 adjacent the pocket 24 , to prevent binding between the clip 58 and the follower 14 .
  • the arm 66 is positioned on the plunger shank 34 such that it is spaced, in a direction parallel to the longitudinal axis 90 , from the cap 50 of the HLA 18 to prevent binding between the clip 58 and the HLA 18 .
  • the clip 58 facilitates handling of the follower 14 and the HLA 18 as a unit, without substantial concern that the follower 14 and the HLA 18 may become unintentionally separated, without requiring any special features on either the follower 14 or the HLA 18 , such as an undercut of the plunger shank 34 , and without impeding the intended motion of either the follower 14 or the HLA 18 , particularly the rotation of the plunger 26 in the body 30 .
  • FIGS. 20 and 21 illustrate the unitized valve train assembly 10 prior to engine installation.
  • the clip 58 maintains the spherical end portion 38 of the plunger 26 at least partially within the pocket 24 of the follower 14 when only the follower 14 is grasped and picked up.
  • the arcuate lip portion 74 may be spaced from the upper surface of the ball socket of the follower 14 by as much as about 2 mm to about 3 mm to allow sufficient play between the HLA 18 and the follower 14 yet prevent the HLA 18 from unintentionally disengaging and separating from the follower 14 .
  • more or less spacing between the arcuate lip portion 74 and the upper surface of the follower ball socket may be utilized.
  • the clip 58 is no longer needed to keep the follower 14 assembled to the HLA 18 . Rather, the clip 58 is only needed to keep the follower 14 from unintentionally separating from the HLA 18 when the engine is only partially assembled. Therefore, during operation of the fully assembled engine, little or no contact between the upper surface of the follower ball socket and the underside of the upper arm 62 or the arcuate lip portion 74 occurs because repeated contact may lead to wear or breakage of the clip 58 .
  • FIGS. 10-16 illustrate a unitized valve train assembly 94 including another construction of the coupling device 98 .
  • Like components are labeled with like reference numerals.
  • the coupling device 98 is secured to the body 30 of the HLA 18 .
  • the coupling device 98 comprises a clip 102 made from a single piece of resilient material (e.g., steel wire) that is bent or otherwise formed in symmetrical halves about a plane containing the central axis 90 of the HLA 18 .
  • the steel wire utilized to form the clip 102 has a diameter between about 0.5 mm and about 0.75 mm.
  • other wire diameters may be utilized depending on the sizing of the other valve train components, and the spacing between the body 30 of the HLA 18 and the follower 14 .
  • the clip 102 includes a first or upper portion 106 selectively engageable with the follower 14 , a second or lower portion 110 configured to engage the body 30 of the HLA 18 , and an intermediate portion 114 interconnecting the upper and lower portions 106 , 110 .
  • the upper portion 106 and the intermediate portion 114 of the clip 102 each include dual parallel segments 118 of the wire that extend from the hoop portion 126 .
  • Each wire segment 118 comprising the upper portion 106 also includes a splayed distal end 122 selectively engageable with the ball socket of the follower 14 to facilitate the connection of the clip 102 and the follower 14 , and to provide resistance to the disconnection of the clip 102 and the follower 14 .
  • the lower portion 110 of the clip 102 includes a circular portion or a hoop portion 126 having an inner diameter D 4 less than the outer diameter D 5 of the cap 50 of the HLA 18 (see FIG. 14 ), resulting in an interference fit between the clip 102 and the body 30 when the hoop portion 126 of the clip 102 is engaged to the body 30 .
  • Such an interference fit substantially prevents the lower portion 110 of the clip 102 from rotating, pivoting, or rocking with respect to the body 30 during operation of the engine.
  • the hoop portion 126 of the clip 102 may have a diameter D 4 between about 5% and about 10% less than the effective diameter D 5 of the cap 50 to yield the interference fit between the clip 102 and the body 30 .
  • the clip 102 may be configured with only a single wire segment comprising the intermediate portion 114 of the clip 102 , and only a single wire segment comprising the upper portion 106 of the clip 102 .
  • FIGS. 10-16 illustrate the clip 102 attached or clamped to the HLA 18 .
  • the hoop portion 126 of the clip 102 is aligned with the central axis 90 of the plunger 26 , the plunger 26 is inserted through the hoop portion 126 , and the individual wire segments 118 comprising the upper and intermediate portions 106 , 114 of the clip 102 are spread apart to receive the body 30 of the HLA 18 .
  • the wire segments 118 are spread apart to allow the hoop portion 126 to move over the cap 50 , after which the wire segments 118 may be released to allow the clip 102 to clamp onto the cap 50 or another portion of the body 30 .
  • a clamping force is exerted on the body 30 by the hoop portion 126 of the clip 102 sufficient to generate frictional forces on the body 30 along and about the central axis 90 of the plunger 26 to substantially prevent the hoop portion 126 of the clip 102 from rotating, pivoting, or rocking with respect to the body 30 during operation of the engine.
  • FIGS. 22 and 23 illustrate the unitized valve train assembly 94 prior to engine installation.
  • the discussion above relating to the unitized valve train assembly 10 in FIGS. 20 and 21 also applies to the unitized valve train assembly 94 in FIGS. 22 and 23 .
  • the arm 110 is positioned on the cap 50 such that it is spaced, in a direction parallel to the longitudinal axis 90 , from the bottom surface of the follower 14 , and particularly the peripheral surface 92 adjacent the pocket 24 , to prevent binding between the clip 102 and the follower 14 .
