Abstract
The present invention relates to a piston connecting bar linear reciprocating running internal combustion engine. It is characterized by that in the original crank block structure of the internal combustion engine a member is added, and the articulated juncture of the slide block and connecting bar is changed into fixed connection, so that on the premise of no changing piston stroke the rotating radius of related member onlyis equal to haft of arm length of crankshaft, therefore the running of internal combustion engine is more smooth, its service life can be prolonged and its thermal efficiency can be obviously raised.
Description
The present invention relates to a kind of internal-combustion piston engine, especially piston rod is the linear back and forth internal-combustion engine of the method for operation.
At present, except rotary engine, known internal-combustion engine mainly is made up of cylinder, piston, connecting rod and bent axle.The tie point of connecting rod and piston does reciprocating linear motion with piston, and the tie point of connecting rod and bent axle is made circular movement with bent axle, so the similar fan shape of the movement locus of connecting rod itself.This of connecting rod kind of motor pattern is for cylinder block, in working time a sizable component perpendicular to cylinder body is always arranged in the overwhelming majority, this component has increased friction, has blocked the smooth and easy operation of piston, be exactly that wearing and tearing increase in addition, shortened the actual life of internal-combustion engine.For bent axle, promote bent axle and make the axial force of the power resources of circular movement in connecting rod, seldom the direction (tangent direction of circle) with the bent axle circular movement is consistent and this axial force is in operation.The power of connecting rod comes from piston, and the moving direction of piston also always becomes the angle of an instantaneous variation with the axial force of connecting rod in most times of operation.This angle that changes constantly is relevant with the instantaneous position of bent axle brachium and crank arm.According to resolution of forces compositional rule and equilibrium of forces law, under the fixed prerequisite of length of connecting rod, the kinetic energy of long crank arm transmission is less than short crank arm.If will shorten crank arm, piston stroke certainly will will be reduced, and this cost is just too big.
In order to overcome the weakness of above-mentioned internal-combustion engine, provide a kind of internal-combustion engine in invention, the piston rod of this internal-combustion engine is the linear motion that is parallel to cylinder-bore axis, and under the constant prerequisite of piston stroke distance and length of connecting rod, the turning radius of internal combustion engine moving force input member only is equivalent to half of former crank arm length.
The technical solution used in the present invention is: in the crank block structure of internal-combustion engine, introduce a member, in addition, the hinge-coupled of slide block and connecting rod changes into and being fixedly connected, just connecting rod and slide block become an integrated member on the axis, can be referred to as the slide block connecting rod member.Improved schematic diagram of mechanism such as Fig. 1, the wherein equal in length of member 1 and member 2.The movement locus of hinge B and hinge A as shown in Figure 2, wherein the wire length of AA ' point is 2 times of BB ' crow flight distance.Observe Fig. 2 and can know that the track of slide block connecting rod is a smooth straight line.
Realize the present invention except adopting above-mentioned linear structure, can also adopt the planetary gear train (as shown in Figure 3) of comparative maturity and the another kind of epicyclic gear train (as shown in Figure 4) of inventor's design.
The invention has the beneficial effects as follows: piston can smooth and easyly move in cylinder, has reduced rate of fault, has prolonged the Acceptable life of internal-combustion engine, has increased power output, has improved the thermal efficiency.Can effectively elongate piston stroke, increase control range by the output of oil supply control engine power.
