Definitions

  • the present invention relates to variable valve lift and duration systems for internal combustion engines, and more specifically to the manufacture of components within such systems.
  • This invention relates to the variable lift and duration mechanism (VLD) previously developed by the applicants of the present invention. It utilises two concentric camshafts the phase of which may be altered relative to one another. The purpose of these two camshafts is that the lift imparted to the valve is determined by the sum of the lift contributed by each camshaft profile. No lift is imparted to the valve when either camshaft is "off-cam”. By varying the phase of the two camshafts, the cumulative lift and duration can be altered. This results in directly altering the opening duration and lift of the engine valve, be it inlet or exhaust.
  • VLD variable lift and duration mechanism
  • the cumulative lift is achieved by the use of a summation lever having cam followers in contact with both sets of cams. If either cam follower is on the base circle of the associated cam, the summation lever merely rocks about a pivot axis connecting it to a valve actuating lever. If both cam followers are in contact with the cam lobes, the summation lever is displaced downwards, and pushes down on the actuating rocker which then pivots about a hydraulic lash adjuster to open the engine valve.
  • the present invention provides a variable valve actuating mechanism as set forth in claim 1 of the appended claims.
  • a three fingered summation lever assembly 110 from a known variable lift and duration (VLD) rocker assembly is shown.
  • the lever assembly 110 includes three cam followers or rollers 112a and 112b, one disposed on each finger, for contacting three cam lobes 150.
  • Two of the three lobes having the same cam profile rotate as a pair on one camshaft and the third rotates on the other coaxial camshaft.
  • Both coaxial camshafts rotate together at the same speed, but also may rotate relative to one another altering the phasing and in turn affecting the valve duration and lift.
  • a typical VLD summation lever assembly 110 and rocker system as described in GB2378729 are shown in figures 1a to 1f .
  • the main body 114 of the summation lever is made up of a single solid component. Such a component, whilst relatively easy to make in low volume or prototype quantities, is relatively heavy and costly to manufacture in high volume production.
  • the main body 114 is cast or machined with a pivot shaft through bore 130 and follower shaft through bores 118. These receive the pivot shaft 120, and follower shafts 122a and 122b respectively.
  • the shafts are typically a form of interference fit within the bores, obtained by heating the summation lever body 114 and then cooling after insertion of the shafts 120, 122a and 122b.
  • the cam followers/rollers 112b are retained on the follower shaft 122b by caps 124.
  • roller bearing elements 126 are installed between the follower and the follower shaft.
  • valve actuating levers 140 are assembled to the summation lever assembly 110, by sliding each of them on to opposite ends of the pivot shaft 120.
  • the pivot shaft acts as a bearing surface within the valve actuating lever allowing the relative rotation of the two levers.
  • the valve actuating levers are prevented from sliding laterally relative to the pivot shaft by virtue of their location on both the engine valve and a hydraulic lash adjuster. There has therefore been no need to provide means for retaining the valve actuating lever to the summation lever assembly.
  • Figures 2a, b and c show a summation lever assembly 210 according to a first embodiment of the present invention.
  • the present invention lies in the construction of the summation lever 210.
  • the summation lever was a cast individual component 114
  • this embodiment is formed from two sheet metal end plates 214a that are press formed, stamped or forged. Holes 216, 218 can be formed at the same time during the stamping process or may be machined to achieve their finished size.
  • the plates are held in relation to one another by mutual connection to a hub 214b.
  • the hub 214b is a simple cylindrical shape allowing it to be inexpensively cast or turned.
  • the hub 214b is received at each of its axial ends within holes 216 of each end plate 214a.
  • end plates are heated prior to insertion of the hub 214b in the holes 216.
  • the end plates may then be cooled to form a heat shrunk engagement with the hub.
  • Any alternative method of attachment may be considered such as brazing, welding, gluing, or interference press fitting.
  • either or both the components may be made from a soft metal, it is possible to provide the surface texturing described above (splines etc.) on only one component, and to rely on the interference fit between the hub 214b and the face plates 214a, to cut or tap a complimentary shape from the engaging opposite component.
  • the hub 214b has an inner bore 230 for receiving the pivot shaft 220.
  • the shaft 220 may or may not be free to rotate inside the inner bore 230.
  • the remaining stamped holes 218 receive the shafts 222a and 222b which support rollers 112a and 112b respectively, in much the same way as the prior art shown in figure 1c .
  • the shaft 222a may be retained in the stamped holes 218 by any suitable means but is preferably held by heat shrinking.
  • rollers or followers 212a and 212b rotate about the shafts 222a and 222b on roller bearings 226, the pair of rollers 212b each being retained on each outside face of the face plates 214a by caps 224, while the single roller 212a is sandwiched, but free to rotate on roller bearing elements 226, between the two face plates 214a.
  • FIG. 3a, b and c the components and construction are much the same as shown in the first embodiment except that the pivot shaft and hub are combined to form a hub pivot shaft 314b to which the face plates 314a are attached as described previously.
  • the pivot shaft is only required to form a rotating connection between the summation lever assembly 310 and the valve actuating lever (not shown). It is therefore unimportant that the hub pivot shaft 314b is prevented from rotating relative to the summation lever body if the valve actuating lever is free to rotate relative to the hub pivot shaft 314b.
  • the advantage of forming the summation lever assembly in this way is the reduced part count which leads to a reduction in cost and complexity and reduces the likelihood of failure.
  • the third embodiment shown in figures 4a, b and c is similar to the second embodiment with the exception that the two face plates 314a of the previous embodiment are replaced by a single pressing folded face plate 414a. This is most clearly shown in the underneath view of figure 4c .
  • the folded face plate 414a is pre folded prior to the insertion (as described previously) of the hub pivot shaft 414b.
  • the face plates 214a, 314a have been assembled on either axial side of the hub 214b, 314b. Due to the folded over design of the folded face plate 414a, this method of assembly is not possible, and so the hub pivot shaft 414b is driven through both holes 416 in each side of the folded face plate, from one side. For this reason, the widest outer diameter of the hub pivot shaft 414b must be no larger than diameter of the holes 416 (except allowing for interference or heat shrink fitting). This is most clearly seen in figure 4b , whereas in previous embodiments, specifically shown in figure 3b , the outer diameter of the hub pivot shaft 314b is such that it cannot pass through stamped holes 316.
  • the advantage of using a folded face plate is a reduction in the number of parts used as well as a greater resistance to twisting. This means that it is less important to prevent rotation of the hub (whether combined with the pivot shaft or not), and so the need to key the hub to the fascia plates can be obviated.
  • the fourth embodiment shown in figure 5a, b and c , is very similar to the second embodiment except that the fascia plates 514a are made from pressed steel components where the pressing has been formed to provide a flange around at least a portion of the outer edge of the component. This is shown most clearly in section in figure 5b .
  • the flange provides support to the sides of the summation lever 514 and increases its overall stiffness. This enables the reduction of the overall mass of the component (by using a smaller material thickness) compared to other embodiments.
  • valve actuating levers 640 are also an integral component of the assembly. This enables the entire rocker assembly 638 to be pre-assembled prior to insertion in the cylinder head, and attachment to the valves.
  • the valve actuating rocker 640 is retained on the roller bearing and pivot shaft by a retaining end cap 644 which is press fitted into the hub pivot shaft 614b. This is especially beneficial when utilising roller bearings 642 between the valve actuating levers 640 and the combined hub pivot shaft 614b as it simplifies and therefore speeds up assembly.
  • the sixth and final embodiment shown in figures 7a , b and c, is similar to the fifth embodiment described previously except that the end caps 720 not only retain the valve actuating levers but also provide the bearing support surface for the rolling element bearings 742. These are assembled to the hub 714b on the summation lever assembly 710 preferably by an interference fit.
  • An advantage is that the interference fit between the end cap shafts 720 and the hub 714b is designed to locally expand the outer diameter of the hub 714b in the region of the face plates 714a. This can either generate or increase an interference fit between the face plates 714a and the hub 714b.
  • a significant advantage of this design over the embodiments shown in figures 6a, b and c is that the material and heat treatment of the end cap shafts 720 (high hardness, high Carbon content) can be specified independently of the hub 714b (which may require a different material if it is to be welded to the face plates 714a). It is preferable for the hub 714b and the face plates 714a to be made from a softer metal which will aid in their assembly, but by using a harder end cap shaft 720 and hence bearing surface for supporting the roller bearings 742 and the valve actuating levers 740, the functionality and longevity of the complete rocker assembly 738 need not be compromised.
  • the rocker assembly 738 is therefore easier to assemble, less expensive to manufacture, more convenient to install into an engine, and due to the use of roller bearings 742 supporting the valve actuating levers, reduces valvetrain losses, therein increasing engine efficiency.
