Fig. 5 is the front cross sectional view that is denoted as a pair of two group of three cylinder/piston supercharged engine with hyperbolic axle of " A " and " B ".In Fig. 5, two group of three piston/cylinder combination body parallel configuration is connected to the independent bent axle 39 (referring to Fig. 6) of same parallel configuration respectively by connecting rod 25.Two bent axles 39 link to each other by engaging gear 45.
Fig. 6 has pair of parallel bent axle 39 and at the top sectional view of two group of three cylinder/piston supercharged engine of the pair of parallel of the engaging gear 45 of each bent axle front portion.The hyperbolic axle of contrary direction rotation provides balance and level and smooth power to produce.Because there is less fuel consumption in the motor smoothness run, less vibration, less pollution, less friction and more effective power produce.
In the second embodiment of the present invention, Fig. 7 is the front cross sectional view that is denoted as a pair of two group of three cylinder/piston supercharged engine with hyperbolic axle and the freewheel mechanism 34 on a bent axle of " A " and " B ".In Fig. 7, structure is similar to the structure among Fig. 5, except a gear 45 has freewheel mechanism 34.
Fig. 8 is the top sectional view that is denoted as a pair of two group of three cylinder/piston supercharged engine with hyperbolic axle and the freewheel mechanism 34 on a bent axle 39 of " A " and " B ".Two gears 45 are engaged with each other.
Freewheel mechanism is a kind of one-way driving mechanism.Sixth version the 31st chapter of the William H.Crouse that McGraw-Hill publishes " Automotive Mechanics " has disclosed a kind of freewheel mechanism.In freewheel mechanism, being positioned on second or the wheel first or wheel just provides and drives., second or the wheel can not drive the first round or the axle.When first or wheel slows down or when stopping, second or wheel " idle running " also continue to rotate.Under the situation of clutch or planetary gear set, freewheel mechanism is described to free wheel device (overrunning clutch) sometimes.Freewheel mechanism comprises insertion type clutch (sprag clutch), centrifugal clutch, two circulation clutches, solenoid clutch, hydraulic coupling, pneumatic clutch or other clutch that is fit to.
Utilization is installed in the freewheel mechanism on " A " bent axle, as shown in Fig. 7 and 8, provide two pistons 60 and 64 of power to drive " B " bent axles by the fuel that injects in the piston 62 top air/fuel compression chambers, and this action is passed to " A " bent axle of side by gear 45.Similarly, provide two pistons 3 and 4 of power to drive " A " bent axles by the fuel that inject in the piston 31 top compression chambers 30., when engine-driven automobile slide, perhaps during the race of engine, the fuel of three pistons of " B " group continues supply and three pistons 3,31 of " A " group and 4 fuel stop supplies, and because freewheel mechanism 34, the piston of " A " group is idle, and then storage of fuels.
Fig. 9 is the front cross sectional view of third embodiment of the invention, comprises a pair of two group of three cylinder/piston supercharged engine with hyperbolic axle and freewheel mechanism on two bent axles 34,66.
Figure 10 is the top sectional view of third embodiment of the invention, comprises a pair of two group of three cylinder/piston supercharged engine with hyperbolic axle and the freewheel mechanism on two bent axles.
When second freewheel mechanism 66 is installed on " B " bent axle, as shown in Figures 9 and 10, according to which crankshaft and piston/cylinder assembly is power train, can make " A " crankshaft and piston/cylinder assembly or " B " crankshaft and piston/cylinder assembly idle.Wearing and tearing like this, in time can be balanced in motor in time.Than idle crankshaft and piston/cylinder assembly, liability fraying is in occurring in bent axle with higher rate and providing in the piston/cylinder combination body of power.Utilize two freewheel mechanisms, on each bent axle one, can make a crankshaft and piston/cylinder assembly temporarily become dynamical system, and make another crankshaft and piston/cylinder assembly temporarily become the power combination subsequently.
Utilize the freewheel mechanism of installing in each bent axle, motor can be controlled so that can replace crank operation by PCMS (process computer supervisory system) or PCM (power train control module).For example, " A " bent axle can and become idle running system (idle train) subsequently as the running 5000km of active force system." B " bent axle can reach 5000km up to it as the running of active force system subsequently under the situation that " A " bent axle as idle running is.Like this, engine scuffing is balanced in two bent axle combinations, and then has prolonged engine life.
If another advantage of two freewheel mechanism structures is that for example bent axle " A " breaks down, automobile does not need to carry out trailer, keeps in repair because automobile can be driven to the garage as dynamical system with bent axle " B ".
Figure 11 is the front cross sectional view of fourth embodiment of the invention, comprises a pair of two group of three cylinder/piston motor with hyperbolic axle and the freewheel mechanism on two bent axles.Motor among the 4th embodiment can be two circulation or four-circulation motors.
Figure 12 is the top sectional view with a pair of two group of three cylinder/piston supercharged engine of hyperbolic axle and the freewheel mechanism on two bent axles.The hyperbolic axle of explanation among Figure 11 and 12, two embodiments that freely turn round can operate with the same way as of the 3rd embodiment of explanation and above-mentioned discussion in Fig. 9 and 10.In Figure 11 and 12, do not exist among the 4th embodiment of explanation, because piston and cylinder all are the diameters that equates from boosting capability.
Though some illustrative aspects and embodiment below have been discussed, have those skilled in the art will recognize that some modifications, displacement, increase and sub-portfolio thereof.Therefore, claim of below adding and the claim of hereinafter drawing are interpreted as comprising the above-mentioned modification of these all in its spirit and scope, displacement, increase and sub-portfolio.
