Embodiment
[0012] with reference to the accompanying drawings, wherein identical reference character is represented identical parts, and Fig. 1 shows the parts of selected diesel engine 10, and these parts are engine assembly 11 parts of (as shown in Figure 3).Engine body 12 (Fig. 1 does not show, but shows and description with reference to figure 3) holds many parts.As common sense, bent axle 14 rotates by piston 16 moving in the casing bore 18 of engine body 12.Piston 16 periodic to-and-fro motion cause reversing on the motor 10, laterally and vertical vibration power.Motor 10 is Dual Over Head Camshaft designs, has 4 rotating cam axles 13,15,17 and 19, and when piston 16 was provided power, these camshaft opening and closing valve (not shown)s were so that allow the air inlet and the exhaust in hole 18.As what understand in related domain, connect the connecting rod 21 of piston 16 thereby make bent axle 17 rotations.Camshaft 15 and 19 is called first camshaft herein, and camshaft 13 and 17 is called second camshaft herein.Camshaft 13,15 influences valve, so that the air inlet and the exhaust in the hole 18 on control engine body 12 1 sides, camshaft 17 and 19 influences valve simultaneously, so that the air inlet and the exhaust in the hole on control engine body 12 opposite sides.Torsional damper of bent axle 14 of being operably connected and flywheel 22 help to alleviate warping force and transverse force.
[0013] active centre line A (the center line A as shown in Figure 2) spaced radial of trunnion shaft 24 and bent axle 14, and almost parallel.Trunnion shaft 24 is roughly parallel to bent axle 14 and is driven and rotate by bent axle 14.Trunnion shaft 24 opposing engine luggines, for example the vertical vibration power that causes because of the rotation of the to-and-fro motion of piston 16 and connecting rod 21 and bent axle 14.Trunnion shaft 24 also is called rotatable driving component herein.Actuation gear 26 connects bent axle 14, so that rotate jointly with bent axle 14.Actuation gear 26 intermeshes with loading gear 28, and drives the loading gear, and this loading gear connects an end of trunnion shaft 24.Actuation gear 26 and loading gear 28 are called rear end gear train 26,28.Loading gear 28 is preferably included in one or more openings 30 that (Lower Half as shown in Figure 1) forms on half of gear or cutting, so that produces during 28 rotations of loading gear uneven.The imbalance of loading gear 28 helps the opposing engine luggine.
[0014] thereby, bent axle 14 and trunnion shaft 24 are operably connected by rear end gear train 26,28, so that the rotation of bent axle 14 driven equilibrium axle 24 rotatably.But as the candidate of intermeshing rear end gear 26,28, the chain wheel radial is in line, each interval is arranged, be connected to each other by chain or belt, bent axle 14 and trunnion shaft 24 are used to be operably connected.This connection be similar to following camshaft 15 with 19 with being connected of intermediate chain wheel assembly 39.
[0015] with reference to figure 2, distance between the active centre line A of bent axle and the center line B of trunnion shaft 24 is crucial: any excessive size gap between these center lines will influence " backlash (gear backlash) " unfriendly, just, the tolerance of size or the elasticity of intermeshed gear 26,28.Can cause gear and bearing fault less than best backlash (just), yet excessive backlash (just, because center line A and B are too far away from getting) causes noise because center line A and B are too approaching each other.Bent axle 14 and trunnion shaft 24 are all supported by the bearing (not shown) of the hole opening that is positioned at engine body 12 rear portions; It is very crucial to control these hole opening positions relative to each other, because it determines the position of center line A and B, thereby the backlash of definite rear end gear train 26,28.
[0016] refer again to Fig. 1, except opposing engine luggine power, trunnion shaft 24 also is used to drive various vehicle components, and these parts can be included in vehicle accessory or the system.In this embodiment, trunnion shaft 24 drives first camshaft 15 and 19 respectively by the first and second overhead camshaft sprocket wheels 32,34, and trunnion shaft also drives hydraulic pressure fuel-injection pump 31, and is as described below.Moment of torsion is by being delivered to these systems with second gear, 38 intermeshing first gears 36 from trunnion shaft 24.Second gear 38 is parts of intermediate chain wheel assembly 39, and this intermediate chain wheel assembly also comprises axle (spindle) 48, and is as described below.First and second gears are called front end gear train 36,38.Thereby first camshaft 15,19 and pump 31 are by front end gear train 36,38 trunnion shaft 24 that is operably connected.Can be used as selection, replace intermeshed gear group 36,38, the first gears 36 to be replaced by first sprocket wheel, second gear 38 can be replaced by the sprocket wheel that forms on the intermediate chain wheel assembly 39, and this sprocket wheel connects the sprocket wheel of first sprocket wheel by belt or chain.
[0017] with reference to the embodiment of figure 1, first gear 36 connects trunnion shaft 24, so that rotate jointly with trunnion shaft 24, first gear is formed with opening 37, so that it is by loading, is similar to loading gear 28 and produces the imbalance of rotation.Effective imbalance of first gear 36 is opposite diametrically with effective imbalance of loading gear 28.
[0018] with reference to figure 2, intermediate chain wheel assembly 39 comprises second gear 38 and axle 48, and this axle connects second gear 38, so that rotate jointly with second gear.In this embodiment, second gear 38 and axle 48 are whole and incorporate; Within the scope of the invention, they also can be separated components.The first and second rotatable transfer units are camshaft actuated chain 50,52 in this embodiment, the first and second rotatable transmission transfer units connect (as shown in Figure 1) respectively between axle 48 and first, second overhead cam shaftgear 32,34, be used for and will drive power is delivered to camshaft 15,19 from axle 48 chain transmission so that set up.Can be used as selectively, the gear teeth on the intermediate chain wheel assembly 39 directly and the gearteeth of camshaft 15,19.
[0019] Fig. 2 sets forth camshaft drive system 53, and it comprises bent axle 14, trunnion shaft 24 and first camshaft 15,19.(in the side view of Fig. 2, first camshaft 19 is blocked by first camshaft 15 effectively, and camshaft 17 is blocked by second camshaft 13 effectively.) second camshaft 13 provides rotating power by first camshaft 15 by the first camshaft driving gear 55, this first camshaft driving gear 55 connects the first overhead camshaft sprocket wheel 32 with one heart, intermesh with camshaft driven gear 57, this camshaft driven gear 57 connects camshaft 13 with one heart.First camshaft 19 also has the camshaft driving gear, this camshaft driving gear in the same way with second camshaft 17 on the camshaft driven gear intermesh so that second camshaft 17 provides rotating power by first camshaft 19.Sprocket wheel and chain can be used for replacing intermeshing camshaft gear wheel, so that power is delivered to second camshaft 13,17 from first camshaft 15,19 respectively.
[0020] because bent axle 14 passes through rear end gear train 26,28 via trunnion shaft 24 drive cam shaft 13,15,17 and 19, rather than gear transmission or sprocket wheel and chain by bent axle 14 front portions, the space of crankshaft front end (near the torsional damper 20) can be used for other purposes.
[0021] in addition, oil hydraulic pump 31 is supported on opening 45 places (as shown in Figure 3) on second gear 38, is driven by the rotation of first gear 36.Pump 31 can be fixing with second gear 38 and axle 48 by spline or alternate manner, so that rotate with second gear 38 and axle 48.
[0022] with reference to figure 2, the rear end gear train 26,28 of appropriate size, front end gear train 36,38 and overhead camshaft sprocket wheel 32,34 allow to realize the rotational speed of hope.For example, the rear end gear train can be designed to 1.0 velocity ratio, so that trunnion shaft 24 perhaps is designed to 2.0 velocity ratio with the speed rotation identical with bent axle 14, so that trunnion shaft 24 is with the twice rotation of bent axle 14 speed.In any example, the size of intermeshed gear 36,38 can be designed to drive oil hydraulic pump 31 with the rotational speed of hope, and the size of camshaft sprocket 60,62 (referring to Fig. 5 mark) can be designed to half drive cam shaft 15,19 with the crankshaft speed of hope simultaneously.If can be used as selectively, oil hydraulic pump 31 is by driving with intermediate chain wheel assembly 39 intermeshed gear, perhaps by connecting with intermediate chain wheel assembly 39 in case with the chain wheel drive of intermediate chain wheel assembly 39 rotations, then oil hydraulic pump can be fabricated to the speed rotation different with intermediate chain wheel assembly 39.
[0023], realizes that the best backlash of intermeshing first and second gears 36,38 depends on the relative position of the center line C of control second gear 38 with respect to the center line B of first gear 36 with reference to figure 2.(the center line B of the first gear 36 roughly center line with loading gear 28 is identical, and they roughly are in line with trunnion shaft 24.) still, if in order to control the backlash of rear end gear train 26,28, the balance axis hole (Fig. 3 43) that be used for balance support axle 24, passes engine body 12 from the engine body rear portion (just, near the rear end gear train 26,28 end) begins processing, then can damage the center line precision of forward horizontal stand axis hole opening (near the opening at the place, 43 ends, hole the front end gear train 36,38 just) with respect to other forward position (for example position of center line C).
[0024] in order to solve the accurate problem of engagement of gear train of guaranteeing trunnion shaft 24 two ends, first and second gears 36,38 are as the part of driving plate assembly 40 and preassembly.Driving plate assembly 40 comprises first and second gear 36,38 and the board members 42.Plate assembly 40 also comprises and is used to allow the bearings and bushings of gear 36,38 with respect to board member 42 rotations.Especially, driving plate assembly 40 is by at first being installed to board member 42 and preassembly with first and second gears 36,38.Then board member 42 front opening (Fig. 3 shows with dotted line) that is placed on the balance axis hole 43 that passes engine body 12 is located.Then board member 42 is installed to engine body 12.Do not require that engine body 12 has the independent opening (because second gear 38 is fixed on board member 42, rather than directly being fixed on the engine body 12) that is used for second gear 38 at the front end place; Thereby, can keep the center line precision of axis hole rear end, do not influence front end gear train 36,38 backlash relative to each other simultaneously.The backlash of front end gear train 36,38 just, is installed to board member 42 with first and second gears 36,38, and is not relied on the position of trunnion shaft hole 43 front openings by preassembled plate assembly 40 controls.The engine assembly 11 of Fig. 3 comprises engine body 12, trunnion shaft 24 (Fig. 1 and 2 as seen) and driving plate assembly 40.It also can comprise vehicle component, for example the oil hydraulic pump 31 (Fig. 1 as seen) and/or the second and second overhead camshaft sprocket wheel 32,24.
