    [0002] Not applicable. BACKGROUND
    [0003] The present disclosure relates to articulated (linked) combine harvesters and more particularly to the improved concave parts on the front tractor or crop processing power unit (PPU).
    [0004] Most agricultural combine harvesters use a rotary splitting and/or threshing system that includes at least one rotor with driven mode turning around a rotating axis within a rotor housing, where the housing it has a lower region which includes a concave perforated portion radially spaced away from the rotor. The impeller may often have a frustoconical inlet end that has a helical belt (or helical belts) around it to convey a stream of crop material into the space between the impeller and housing. The rotor main body will typically have an array or pattern of threshing elements, which most commonly include file bars and separating elements and/or elongated teeth, all of which project radially outward from the rotors. themselves into space. File bars and split bars are configured differently to perform different functions, and may not all be present in a given rotor design. The functions of the file bars include cooperating with one or more vanes and guides, typically disposed around the upper portion of the inner circumference of the rotor housing, to transport a blanket of crop material along a generally helical path. , through space, while cooperating with the reed or reeds and/or guides, and other aspects of the concave part, e.g. bars, perforations and the like of the concave part, to break the larger components of the harvest material into their constituents, the namely, major element or constituents of crop residue, commonly referred to as straw, which includes stems, stems, ears and the like, and minor constituents comprising grain and minor elements of non-grain material (MOG), as well known.
    [0005] File bars are usually relatively narrow and generally concentrated closer to the inlet end of the rotor and include a plurality of sawings that define grooves in the threshing element. These grooves are oriented at small acute angles in the direction of rotation of the rotor, or generally aligned therewith, to spread or smooth the blanket of crop material and decouple smaller constituents from the crop material, thereby allowing the grain falls through the openings in the concave part. Straight splitting bars, in counterpoint, are often longer and generally located closer to the discharge end of the rotor and include one or more bars, with at least one sharp edge extending perpendicularly in the direction of rotation for plowing the larger components of the crop mat and move them away from the smaller grains and the MOG. The function of typical straight bars is to interrupt the consistent flow that shorter lime bars establish, and thus cause the grains to be shaken out of the straw due to turbulence.
    [0006] To minimize damage to the grain, it is desirable to separate the grain from the blanket of crop material so that it can fall through the openings in the concave part as far forward in the threshing system as possible. The number and size of openings in the front portion of the concave portion are limited, however, and it has been observed that some of the threshed grains travel over additional file bars or other threshing surfaces in the rotor before falling through an opening in the rotor. concave part.
    [0007] It has also been observed that when the relatively narrow lime bars engage the blanket of crop material, some of the larger portions, particularly corn cobs, will deflect rather than flow over the lime bars. As a result, the grain stays in the threshing system longer, and encounters more threshing elements, where there is a risk of damage to the grain and an increased likelihood that the ears will break.
    [0008] Consequently, what is sought is a threshing system for an agricultural combine that includes threshing elements that overcome at least some of the problems, deficiencies or disadvantages presented above. BRIEF SUMMARY
    [0009] A cage and rotor assembly is disclosed that includes a skeleton of curved spaced-apart members affixed to horizontal (upper and lower) spaced members extending laterally therebetween and surrounding the rotor. One of the curved away side members is finished with curved fingers. Three concave inserts insert laterally into the skeleton gap, 270° around the rotor. One of the concave inserts has straight fingers that weave between the curved fingers of the skeletal side member. A control assembly of boards that have arcuate slots located at 3 of the pivots of the skeleton assembly, control rods connected to the skeleton pivots, and an actuator connects to the control rods, in an end-effect arcuate rotation of the rods. control, which results in the synchronous rotation of the arcuate slit plates so that the interlaced straight fingers move closer or farther from each other, with the curved fingers of the skeleton assembly fixed for different types of grain. The overlapping and interlocking concave inserts allow the three 270° sections to wrap around to expand and contract their combined circumference as the concave parts move closer and further away from the oscillating rotor diameter. This movement is necessary in order to adjust to various crops and conditions, especially intentionally, to prevent wide gaps between concave inserts, especially when the assembly is in its open position. A reasonably identical grille assembly, which may or may not allow adjustment, follows and is adjacent to the concave skeleton, and also surrounds the rotor. Certainly, the number of concave inserts could be greater or lesser in quantity and extend to less or more than 270°. For present purposes, the two different sets of fingers “intertwine”, in which both are laterally shifted (side by side) but are also vertically shifted (up and down). The key to interlaced fingers is that they move closer together and farther apart for different types of grains.
    [0010] A concave control assembly, for a concave assembly, includes a skeleton to receive at least two end-to-end concave inserts. At least two concave inserts are housed within the skeleton for threshing grain along with a rotor assembly. Turntables having arcuate slots are located where the at least two concave inserts meet and are carried by skeleton pivot pins and are pivotable therewith. Control bars connect to and between skeleton pivot pins. An actuator connects to the control bars at one end of one of the control bars, whereby the actuator actuation moves the control bars, causing the arcuate rotation of the arcuate slotted plates to move the at least two concave inserts end to end. edge closer and further away from each other.
    [0011] A grate control assembly, for a grate assembly, includes a skeleton to receive at least two end-to-end grate inserts. At least two grate inserts are inserted into the skeleton to separate grains along with a rotor assembly. The turntables have arcuate slots and are located where the at least two grate inserts meet and are carried by skeleton pivot pins and are pivotable therewith. Control bars connect to skeleton pivot pins and are located between them. An actuator connects to the control bars at one end of one of the control bars, whereby the actuator actuation moves the control bars, causing the arcuate rotation of the arcuate slotted plates to move the at least two grid inserts. edge to edge closer and further away from each other.
    [0012] Concave Assembly and Grid Assembly are put together, wherein both Concave Control Assembly and Grid Control Assembly work together to adjust both Concave Assembly and Grid Assembly. The actuator of some of the grate inserts can be manual and/or electric.
    [0013] These are other features, which will be described in detail below. BRIEF DESCRIPTION OF THE DRAWINGS

    [0041] Referring initially to Figures 1, 2, 3 and 4, an articulated combine, (10), consists of an electric PPU, (12), a rear grain cart, (14), and a hinge, (16), which connects the PPU (12) with the rear grain cart (14). The details of the articulation joint (16 are disclosed in a common belonging order, serial number 14/946,827, filed November 20, 2015. The PPU (12) carries the grain cutter head, (18), cabin operator, (20), grain handling and cleaning assembly and motor mechanisms. The PPU (12) is devoid of any grain storage, which is unique to the rear grain cart (14). Although both the PPU (12) while the rear grain cart (14) is shown being loaded by wheel mounts, one or both could be on rails. A screened air inlet, (15), is located above the PPU (12), where the air is probably the cleanest around the combine (10).
    [0042] A pressure relief auger assembly, (22), is in the folded home position, and is loaded by the rear grain cart (14). The grain trolley (14) is also provided with a folding roof, (24), shown in an open position, but which can be folded inwards to cover the grain stored in the rear grain trolley (14). The folding roof (24) may be made of metal, plastic or other suitable material, but may be made of durable plastic for weight reduction and easy folding/unfolding. A grain storage silo (28) (see also Figure 14) carried by the grain cart (14) may be made of plastic also to maintain desirable weight reduction; although the same could be made of metal too at the expense of weight. All plastic parts can be filled with fiber reinforcement or particulate in a conventional manner and could be laminated in the construction. Additional details on the rear grain cart (14) can be found in the Common Property Application, Serial Number 14/946,842, filed November 20, 2015.
    [0043] Referring now to Figure 4, the operator has access to the cabin (20) by a ladder assembly, (30), which extends upwards just above the ground, and will be more fully revealed in the order of common property, serial number 62/375,986, filed August 17, 2016. The outer layer or coating has been removed in Figure 5 to reveal the components housed within the PPU (12). A fan assembly, (32), is centrally located for air to enter through the screened air inlet (15). This location was chosen as it will likely be the cleanest airflow around the PPU (12). The radiators, as typified by a main cooling system airbox, (34), surround the fan assembly (32) and are cooledly connected to a pair of motor mechanisms, (36) and (38), located on each side of the main cooling fan assembly (32). The motor mechanism (36) powers the hydraulic system for the articulated harvester (10), while the motor mechanism (38) powers all other articulated combine harvester components (10). The exhaust, after the treatment assembly, (40), cleans the air for emission control. When starting the motor mechanisms, which will typically be diesel engines, the motor mechanism (38) is first turned on so that the coolant flowing through the motor mechanism (38) will heat the motor mechanism (36). and hydraulic fluid for the articulated harvester (10). The aspect of dual motor mechanisms will be described in detail in the common property application, serial number 62/358,629, filed July 6, 2016 and the air intake assembly will be described in detail in the common property application, serial number 62/376,512, filed August 18, 2016. Other components visible in Figure 5 will be described in detail below.
    [0044] Referring to Figure 6 below, the grain cutter head (18 will typically be between about 9 and 15 meters (between 30 and 50 feet) wide and separates the crop in various ways from its The grain cutting head (18) is carried by a feeder face adapter, (44), for a feeder mechanism assembly, (50), as described in detail in the order for common property, serial number 62/358,618, filed on July 6, 2016, which transports the separate crop consisting of both stem and grain. By industry convention, any material other than grain is referred to as “Non-Grain Material ” or simply “MOG”.
    [0045] Processing in the opposite direction, the crop material hits the end of the feeder assembly (50) with speed, and is projected backwards and upwards, to the walls of a transition cone, (52), which is a robust structure that describes the shape and direction of material flow and, in general, narrows the flow of crop material towards both the sides and bottom of a rotor inlet cone, (52), of a rotor swivel, (54) (see Figure 12). The rotor inlet belt (56) is identified as the front rotor portion (54) which are auger belts of predominantly 2, 3, 4 or greater, attached to the outer layer of rotor (54), and serve both to propel crop material backwards in a rotor cage (58) and to begin rotating the crop material (as viewed from the rear of the module) around the periphery of the rotor cage (58). Rotation of rotor (54) occurs by virtue of a pulley assembly, (42), a gearbox, (60), and shaft, (62). The rotor cage (58) is the empty space located within the rotor tube and is formed by concave parts, gratings and an upper cover with vanes that define the rotor tube or cylinder, within which the rotor rotates and supplies all the stationary surfaces against which the grain is threshed and separated.
    [0046] The process inside the rotor cage (58) distributes the crop material out of the end of the belts (56) and up to the file bar mounts for threshing and grain separation (see Figure 12). These file bar mounts can be rough cast iron configurations that impact, move and pinch the crop material in order to dislodge the grain from the MOG parts of the plant so the grain can be removed from the stream. A typical file bar, (64), as are all file bars, is attached to the rotor (54) by bolting it to the barnacles, as typified by a barnacle, (66), which, in turn, is welded to the rotor (54) at carefully identified locations to form the desired spiral patterns on the rotor as a whole. The file bars will be located in a spiral configuration, around the rotor (54), so that the harvest material is laminated, twisted and rubbed against itself, whose net affectation will have to be significantly intensified and with threshing action. substantially “softer”, thus almost eliminating the grain damage common to those units that “hit the crop with steel” to achieve threshing. Each file bar assembly is then composed of a file bar and a barnacle.
    [0047] Entrance to the rotor cage (58) begins the threshing process, as the file bars rub the crop material across the concave parts, (70) (see also Figures 10 and 13), which are typically porous structures made of steel, which surround the lower 270° portion of the rotor cage periphery (58) and are divided into three sections, each of which covers 90°. The concave portions (70) may have numerous actual structural constitutions, but generally provide a rough surface to cause significant rubbing and turbulence between the file bars and the upper surface of the concave portions (70). Additionally, the concave portions (70) are also very porous (have holes) to allow released grains to exit through the holes to be introduced into a cleaning area (68). Concave inserts (often simply called “concave parts”), as typified by a concave insert, (72) (see Figures 13 and 18), change from one type of surface to a different type of surface as the type of crop and condition dictate. Ideally and typically, this front section (~%) of the rotor cage length (58) can remove nearly 75% of the seized grain from the MOG material, and which, coincidentally, passes, perhaps at more than 80% of the MOG, to a separation section or cleaning section (68) which follows, and is described in greater detail in common property application, serial number 62/358,629, filed July 6, 2016. Typically, for all combine harvesters, the parts concave (70) are suspended from above so that they can be moved in and out with respect to the oscillating diameter of the file bars to cause a change in the relative clearance of the upper surface of the file bars with respect to the inner surface of the concave parts. This allows for the variation of aggressiveness in the threshing process in contrast to the type and condition of harvest, and will be described in detail later in this document.
    [0048] The rotor cage separation section (58) is located immediately behind (upstream) the threshing section, and is for the most part identical to the threshing section. By tradition, the same inserts that are located in the threshing area are now called grates, (74) (see Figure 19), when in this rearward position of the process. Typically, the grids (74) are fixed in place, and do not snap in and out, as concave parts (70) do; however, due to the fact that the mechanisms are identical to the concave supports, the grids (74) could be adjusted, and this capability will be disclosed in the present document. The intended function of the grids (74) is to separate the remaining grain from the MOG; however, since the MOG to grain ratio now significantly favors MOG, the proportion of MOG coming out of the grates (74) is much higher than that of the concave parts (70). All this material falls towards the sieves of the cleaning system (68).
    [0049] An important new feature on the rotor cage (58) is a top cover vane assembly, (76) (see Figure 10), as typified by a vane, (78), located on the underside of the flat roof section of rotor cage (58). The vanes are basically steel angle plates that are bolted through the top cover onto a horizontal leg, and project down into the crop stream with the vertical leg at 90° to the crop. These vanes serve to regulate the speed of material flow through the rotor cage (58), thus affecting the relative aggressiveness of threshing and separation. When set at an angle more perpendicular to the axial flow, the vanes slow the flow rate; when set at a less perpendicular angle (“delayed” or “accelerated” in language), reeds allow for a faster flow of less powerful intensity. All other rotary combine harvesters have a curved top cover that requires the cage vanes to be curved as well. This curvature sincerely limits the adjustment range, due entirely to the fact that since a vane (for example) that would conform to a line that is perpendicular to the axial on the cage cylinder would be too curved to fit into a position that was 30° off the perpendicular. With the flat surface revealed in this document, you will have the top cover. The vanes of the top cover vane assembly (see Figure 7) are attached to the tubular control bars, (80) and (81), which are moved by cylinders, (82) and (83), to control the angle of the same. Control can be exercised remotely from the cab (20) by the operator to provide the operator with a tool that will be effective in controlling yield versus threshing versus separation to optimize combine productivity (10). The top cover vane assembly (76) is described in greater detail in Common Property Application, Serial No. 62/358,624, filed July 6, 2016.
    [0050] Finally, the MOG (which by convention is now renamed straw or waste), now located at the rear of the separation area (grilles (74)) is ready to be unloaded from the rotor cage (58 ) and spread over the soil. On the PPU (12), this will be done in a very unconventional way, through the discharge openings in the rotor cage (58), to discharge assemblies that contain straw chopper assemblies, (90) and (92) (see Figure 9), where rapidly rotating drums with numerous oscillating blades will reduce the length of the pieces of waste and drive them horizontally and transversely outward at high speed. Assisting the chopping process are stationary knives, (“counter knives”, “fixed knives”), not seen in the drawings, which act as shear surfaces to retain the long residue so that the oscillating (sharp) knives better cut the residue. .
    [0051] Shortly after chipping and propulsion, the waste pieces will encounter the straw cover mounts, (94) and (96) (see Figure 9), which are used as a deflector to influence the direction of the pieces, so that some remain at a distance from the vehicle, while others, variably, fall at distances from the vehicle, causing an ideally uniform distribution of the pieces over the ground surface. The PPU (12) will have two sets of these chipper and knife assemblies (90) and (92), one on each side, as seen in Figures 8 and 9 and described in detail in the commonly issued order, serial number 62 /375,468, filed on August 16, 2016.
    [0052] Returning to the MOG and the grain being expelled through the concave parts (70) and the grates (74), these materials exit the inserts at reasonably high speed and in a trajectory imposed both by their angular speed of rotation in the cage (58) and from the centrifugal force imparted by the rotation of rotor (54), whose net is largely an external (if not radial) outlet of the rotor cage (58), down into the hollow space below the rotor cage (58). rotor (58) and above the cleaning system assembly (68) (see Figure 6) known as the “chaff separator” (its purpose in the process is to help remove the lightest and largest chaff from the grain, allowing the grain to fall out, while rejecting the chaff to be blown out of the back of the machine). However, in accordance with the present disclosure, an additional cleaning component is provided which benefits from such an exit velocity of the material mixture that it leaves the separation system. The front shield (98) of the cage/rotor support structure has shaded slits (see Figure 8) in it which will allow high velocity air to be forced downward into a chamber for which the shield is a wall. , where the air power is a cleaning charge fan assembly (see Figure 6) located above the rotor cage, in front of the main cooling system airbox (34) (see Figure 6) . The load fan assembly will collect exhaust air from a cooler assembly (34), which transmits the new speed to it and sends it down through the chamber formed by the front cage shield (98), the rotor inlet cone (52), a separator side plate and a cover plate to complete the chamber. The purpose is to distribute air from the top of the PPU (12) downwards, through the chamber and to the inlet of the cleaning fan (33), located in front of the shaft, as explained in detail in document No. USSN 62/358.629 , above mentioned.
    [0053] As a matter of secondary guarantee of high capacity and due to the fact that the PPU configuration (12) disclosed allows for this, a bonus screen assembly is provided as disclosed in commonly issued order serial number 62/ 369,307, filed August 1, 2016. Unbeknownst to the rest of the industry, these bonus screens can, via the rear axle, for the combine harvester (10), be in the rear module (12), not next to the screens. Then the PPU frame (12) will protrude outward, wider, once past the front tires, and fill that space on either side of the main sieves, the shortest and narrowest sieve members, bonus sieves, which , in total, will add about 20% more sieve area. Also, remembering the condition of having a much higher ratio of MOG being expelled from the rear of the separation area, this bonus screen area will add the additional cleaning area in the back, where cleaning is more difficult due to to higher MOG concentrations if it is in the air stream or on sieve surfaces.
    [0054] Under most of the front length of the main screens, a clean grain conveyor, a conveyor belt (running in the backward direction at the top) catches the grain as it falls and transports it to back to a clean grain cross auger. A secondary but equally important function of the flat top of the conveyor is to serve as a converging chamber versus the bottom screen, so that air that is moved backwards by the cleaning fan is progressively forced to be directed upwards through the sieves, thus feeding the pneumatic cleaning function of the cleaning system. If the straw MOG ended up falling through both sieves, there would still be another chance for that piece of MOG to be blown back and perhaps out of the system. Again, this is disclosed in detail in USSN 62/358,629 cited above.
    [0055] The fate of the separated cleaned grain exiting the various cleaning systems in the PPU (12) and its transfer to the grain cart (12) is disclosed in the common property application, serial number 14/946,827 cited above.
    [0056] Finally, the PPU (12) will contain a tailings return system, as revealed in detail in the Common Property Application, Serial Number 62/376,957, filed August 19, 2016, which will be located below and behind the rear of the cleaning assembly (68). Material that is small enough and dense enough to fall through the extreme rear section of the straw chopper, termed a straw chopper extension, and material that, due to size or low density, cannot fall through the straw chopper. bottom sieve, will be distributed to a tailings auger ditch. In the trench, there is a transverse auger of tailings, an auger with an opposite belt, which, at this moment, transports the material out through the auger, from the middle. As the material hits the side plates of the main frame, it enters the tailings elevator, one on each side of the frame. The run on a toothed belt at the end (on each) of the cross auger will be a roller chain with backward sloping blades that are also angled to move material inward against the inner wall as it is conveyed. up. The pitch and slope of the shovel reduce conveying efficiency, while also increasing drumming and rubbing of unthreshed grain against the walls and outer ring of the elevator chute. This “rethreshed” material will then be fed back into the cleaning system (68) above the bonus screens via the auger belts onto an upper tailings drive shaft to make another attempt at proper rescue and cleaning, or to be rejected again, and in each case it will, in one way or another, be ejected from the system.
    [0057] At this point, in the disclosure, one should consult Figures 8 and 10, in which the support for the concave parts (70) and the grids (74) is shown. In particular, a front bulkhead, (98), an intermediate bulkhead, (100), and a rear bulkhead, (102), provide support for the rotor/cage structure. Referring to Figures 13 to 22, the concave parts (70) and the grids (74) are revealed in detail. A skeleton, (104), supports and accepts concave inserts, such as the concave insert (72), and a skeleton, (105), which supports and accepts a grid insert, (106). There are three cross sieve inserts and three sets of cross sieve inserts that bend 270°. Figure 20 shows the frame assembly (104), the concave insert (72), a concave insert (108), and the concave insert (110). One end of the concave insert (108) is a flat plate, 109, for permanent attachment to the skeleton (104), while the other end has a finger assembly, (112). The end with the concave insert finger assembly (108) is curved and partially surrounds an upper bar, (114), the skeleton portion (104), by virtue of its U-shaped end to receive the upper bar (114). ). The insertion of the concave insert (108) into the skeleton (104) is seen in Figure 22, so as to enclose the concave insert (108) which is moved from the side to the position with the plane (109), which is screwed or, otherwise fixed to a flat bar (116) of the skeleton (104), and the U-shaped upper end admits the bar (114). All concave inserts are fixed in the same way. In fact, the grid inserts are similarly configured and inserted into the frame skeleton (105) in the same way. The revealed design allows for easy installation and removal of any concave part or any of the concave part or grate inserts. A curved finger assembly, (111) (see Figure 19A), is part of the skeleton assembly and is present for both the concave assembly and the grid assembly, and interacts with the finger ends of the concave and inserts. of grating to accommodate the size of the grain being handled.
    [0058] Referring further to Figures 14 and 15, the skeleton ends (104) are configured to receive rotating bars, (118), (120) and (122), and a fixed bar, (124). As seen more clearly in Figures 14 and 15, the slotted plates, (126), (128) and (130), which have arcuate slots, are attached to the swivel bars (118), (120) and (122), and are rotated by a cylinder assembly, (132), so that the finger assemblies are in a closed position. In this closed position, the screen inserts are in a tight configuration with respect to the rotor (54), for small grain. As seen more clearly in Figures 16 and 17, the cylinder assembly (132) has rotated so that the finger assemblies are in an open position for large grain. Simultaneous movement is achieved by the cylinder assembly which is attached to the connecting bars, (134) and (136). A similar set of tie bars is provided at the other end of the hollow part assembly. The arcuate rotation results in the fingers being moved in an arcuate motion and in an up and down motion. These simultaneous movements result in the fingers, straight on one side and curved on the other, moving closer and farther away from each other, while moving briefly and simultaneously up and down. Additionally, the cylinder assembly (132) can be remotely actuated by the operator. Additionally, while hydraulic cylinders are shown in the drawings, such cylinders (or actuators in general) could be linear actuators, pneumatic, electric motors or other assemblies. The actuators are “fed” for the present purposes.
    [0059] Although the revealed concave inserts exceed 270°, a greater or lesser amount of turns could be designed into such concave inserts. Furthermore, the hollow sections can be adjusted independently, not only to effect a change in clearance to the rotor, but also to achieve multiple pinch points around the periphery, in the same amount as the number of peripheral sections. The drawings show 3 such concave sections that result in triple concave clearance convergence for the rotor. The net effect of this triple convergence is the possibility for a single crop to pass around the rotation periphery to have threshing and separation equivalence for three separate passes, from typical configurations, which greatly increase threshing and harvesting efficiency. separation. The disclosed design then allows the entire designated "separation" area of the grates to be reconfigurable to the type of grate separation surface chosen, as opposed to fixed-size holes. Furthermore, the grilles could also be designed for simple clearance and tightness adjustment, if desired.
    [0060] The flexibility of the concave adjustment mechanism allows it to be synchronized or adjusted independently. The same is true for the grates, provided that the grates can be synchronized with the concave parts. Concave inserts and grid inserts are easily and quickly inserted and removed according to your revealed design. All concave inserts and all grate inserts are the same in design, allowing any insert to be installed in any location. Finally, concave inserts have finger panel assemblies that move closer and farther from each other as the concave gap is adjusted in and out. These fingers on the panels are offset relative to each other to effect large change in the open area and the shape of the open area to provide the prescribed separation based on the type of crop.
    [0061] Returning to Figure 13, it will be observed that the spacers, (138), (140), (142), and another not seen, provide a break between the bar (118) for the concave parts (70) and a bar (119) for the grates (74). The same is true for a slash (122) and a slash, (123). Such spacers could be omitted and the respective bars, be continuous for the grates (74), to rotate, as do the concave parts (70). Alternatively, the grids (74) could be constructed as are the concave portions (70), for independent rotation and adjustment.
    [0062] Figure 23 shows the frame assembly (143) with its various members. Note the overhang of the frame behind where the tires, locations (144) and (146), are located, to accommodate the additional treatment assemblies for grain separation, as described above and in the related patent applications. The front split shield (98) is seen in this view as well. Some of the boards will contain holes or openings to achieve weight reduction without sacrificing structural strength.
