Abstract
The present invention relates to a kind of energy conversion driving unit of stroke piston combustion engine, it is to drive the connecting rod that two symmetries are biased in the cylinder center both sides with a piston, respectively connecting firmly a number of teeth on the bent axle of these two connecting rods equates and pitch wheel, can eliminate the side pressure of piston countercylinder wall like this, reduce energy loss, and can increase the effective torque that is produced.When reciprocating motion of the pistons, drive two bent axles and do the synchronous backward rotation, two bent axles can come mutual transferring power by the aforesaid a pair of gear that is meshed.
Description
The invention belongs to stroke piston combustion engine, specifically the energy conversion driving unit of internal-combustion engine.
The practical efficiency of existing stroke piston combustion engine is lower, and one of its reason is caused by the transformation of energy driving mechanism.This transformation of energy driving mechanism comprises cylinder, piston and by the connecting rod of piston actuated, each piston only drives a connecting rod.Therefore, a side pressure and surface friction drag must be arranged between piston and cylinder wall, this not only causes the wearing and tearing between piston and cylinder wall, and will consume part energy.And the pendulum angle of side pressure between piston and cylinder wall and connecting rod is relevant, is wearing and tearing and the resistance that reduces cylinder wall and piston space, and its side pressure can not be too big, and promptly the pendulum angle of connecting rod can not be too big.The pendulum angle of connecting rod is less, and then the power that acts on the crank of connecting rod is less, and the effective torque that is produced is also less.
The purpose of this invention is to provide the bigger energy conversion driving unit of reciprocating-piston internal combustion engine of a kind of thermal efficiency effective torque higher, that produced.
The solution that realizes the object of the invention is: drive two connecting rods simultaneously with a piston.Identical and the symmetrical cylinder centerline both sides (certainly, the offset or dish of crankshaft center should greater than crank throw) that are offset to of their structure, each bent axle connects firmly a gear, and the number of teeth of this two gear equates and is meshing with each other.Therefore, when piston in cylinder during to-and-fro motion, can guarantee that two connecting rods do the synchronous backward motion, promptly two bent axles are done the synchronous backward rotation.Because two bent axles are provided with two identical and pitch wheels of the number of teeth, simultaneously can also mutual transferring power between two bent axles.Promptly when one of them bent axle during as output shaft, another bent axle by above-mentioned two gears with transmission of power to output shaft.That is to say that the power on the output shaft is the power sum of two bent axles.
The present invention has been owing to adopted the connecting rod of two symmetrical distributions, so the side pressure between piston and cylinder wall equals zero theoretically, its frictional force also equals zero.We can say that in real-world operation, the frictional force between piston and cylinder wall is minimum, their wearing and tearing also are minimum, thereby the operating life of cylinder and piston is improved, and energy loss reduces, and efficient improves.Simultaneously, less by the caused vibration of connecting rod swing.Owing to eliminated the side pressure between piston and cylinder wall, reached the purpose that increases effective torque so can increase the offset or dish of connecting rod.In addition, connecting rod of the present invention is offset to cylinder centerline, so between the crank position when crank position during top dead center and lower dead center one angle is arranged, promptly the angle that turned over from the top dead center to the lower dead center of crank is less than 180 °.That is to say that compare with existing internal-combustion engine, under the same conditions, the effective rate of utilization of combustion gas expansion working of the present utility model is higher, thereby heat loss is less.The present invention is applicable to four-stroke or two stroke IC engine.
Below in conjunction with accompanying drawing content of the present invention is described in detail.

Fig. 2 is the phase diagram of piston of the present invention when being positioned at lower dead center.
Fig. 3 is one of structural representation of second embodiment of the invention.
Fig. 4 be second embodiment of the invention structural representation two.
Fig. 5 is a connecting rod free-body diagram of the present invention.
Fig. 6 is the structural representation of third embodiment of the invention.
As shown in Figure 1 and Figure 2: piston 2 is in cylinder 1, piston 2 is provided with on two parallel and be symmetrical in the wrist pin 3 of piston center line, two bent axles, 4 symmetries are offset to cylinder 1 center line, and are bearing on the casing 5, connecting rod 6 respectively with wrist pin 3 and bent axle 4 on axle journal 7 link.End at bent axle 4 connects firmly the gear 8 that a number of teeth equates respectively, and two gears 8 are meshing with each other.When piston 2 to-and-fro motion, drive two bent axles 4 by two connecting rods 6 and do the synchronous backward rotation.In actual use, can choose a bent axle wantonly as output shaft, and the power on another bent axle is delivered on this output shaft by above-mentioned a pair of pitch wheel 8.
The present invention can also adopt structure shown in Figure 3, promptly links by a small rod 9 between two connecting rods 6 and the piston 2.Prevent in the time of can certain offset or dish being arranged in two connecting rod mechanisms so on the one hand that connecting rod 6 and cylinder wall from colliding; Also can proofread and correct on the other hand because the caused piston skew of alignment error.State when piston 2 is positioned at top dead center and lower dead center is as shown in Figure 4: as can be seen from the figure, when piston 2 is positioned at top dead center and lower dead center, be that connecting rod 6 is with crank 10 point-blank the time, this of connecting rod 6 has an angle α between two positions, the angle that is turned over to lower dead center crank 10 from top dead center is 180 °-α, and single linkage mechanism, from the top dead center to the lower dead center, be generally 180 °, this section period is the process of combustion gas expansion working just, so the heat loss during the combustion gas expansion working reduces, the effective rate of utilization of its work done can be improved.
Fig. 5 has represented the stressing conditions of connecting rod 6 under different angle of declination.P-piston pressure among the figure; The maximum active component of piston action on connecting rod in the single linkage mechanism of T-; The cross component force of piston action on cylinder wall in the single linkage mechanism of N-; " bent axle of the present invention is the component of piston action on connecting rod 6 when different offset or dish for T ', T.As previously mentioned, the power of two bent axles 4 can transmit mutually, and when one of them bent axle during as output shaft, the power on it is equivalent to the twice of a bent axle power, and promptly maximum active component is 2T ' or 2T ".In from figure to find out 2T "＞2T '＞T, promptly bent axle 4 offset or dishes are big more, active component is big more, then effective torque is big more.
When the offset or dish of two bent axles 4 is big, can a pair of mesomerism gear 11 be set between the gear 8 of two bent axles 4, its structure is as shown in Figure 6.
