Abstract
Provided is a double-crankshaft efficient engine. A traditional design scheme is changed, two connection rods connected in a crossed mode below a piston are connected with two crankshafts respectively, and the two crankshafts are connected with flywheels through synchronous gears. A main push connection rod is of a hydraulic structure, and a middle plunger rod can stretch and retract according to needs. Besides, the other auxiliary connection rod is designed into a U shape, and the lower end of the auxiliary connection rod is provided with a buffer spring. During ignition, high pressure on the piston is loaded to the main push hydraulic connection rod with a long crankshaft force arm and small torsion resistance, and large torque force is transmitted to a transmission system. When the main crankshaft force arm is rotated by 120 degrees, the middle plunger rod of the main push connection rod is pressed downwards and retracts, force on the piston is completely loaded to the auxiliary U-shaped connection rod with a long crankshaft force arm at the moment, the torque force on the piston continuous to be transmitted to the transmission system, and the piston is driven to complete the exhaust, gas suction and compression strokes. Thus, the two crankshafts alternately complete pressure conversion, so that the output torque force is greatly improved.
Description
Technical field
The invention relates to motor Synergistic and energy-saving technology.
Background technique
Known bent axle is widely used in straight line motion to be converted in the machinery of circumference, in reciprocating-piston engine, more can be rated as perfect adaptation, show that in cylinder of internal combustion engine, on piston, the size of power is by the ratio of the volume with acting front-bank rotor housing space producing expanding gas according to available data, on top dead center, its spatial volume radix is minimum needs that the amount of expanding gas is relatively little just can obtain larger active force, when bent axle after piston setting in motion only has 60% by 0 °-145 effective acting, and other acting of 40% is all transformed to connecting rod to the frictional force of bearing shell flogs a dead horse, transmission of crankshaft also only can be fully transmitted on bent axle acting on 90 ° of points, all there is the idle work done more or less in other any point, but on top dead center, increase 5 times at the spatial volume of 90 ° of these upper cylinder bodies than piston, at bent axle 0---in the rotation of 145 °, the motion of piston will cause the increase gradually of cylinder space, and the space of the idle work that namely a large amount of expanding gas does can be transformed into the frictional force of bearing shell to bent axle, and piston needs to move to the circumference turning back to 575 °, bent axle after bottom dead center and becomes the useful work that piston linear motion autophage falls, at this moment the dynamic merit of institute on bent axle loses more than 60% again in the transfer, it is also more than the loss 40% during acting, visible transmission of crankshaft self loses the energy loss caused in the exchange carrying out power can reach more than 80%, and the power root of reciprocating internal combustion engine waste is just in the transmission and conversion of power, an imagination: so, can there is a kind of constant moment that cylinder straight line motion is converted to the driving mode of circular movement? have, point of contact cylinder piston linear reciprocating motion being applied to circumference is just passable, however the fatal part of this " tangent-type motor " be straight reciprocating motion and circumference continue to rotate between contradiction, there is no a kind of effectively mechanical device at present can be the unidirectional drive to circumference by tangent line moment " rectification ".
Summary of the invention
In order to reduce the loss that engine power is transmitted, the invention provides a kind of double-crankshaft high efficience motor; It changes traditional design scheme, and below piston, cross-coupled two connecting rods are connected with two cover bent axles respectively, and two cover bent axles are connected with flywheel by synchromesh gear; Promoting mainly connecting rod is a hydraulic structure, to be pressure oil chamber outer ring under plunger rod be, and accumulator allows oil flow back to accumulator from pressure oil chamber by the unlatching of a magnetic switch control valve, bottom is provided with a steel ball makes pressure oil can only be unidirectional from accumulator suction pressure grease chamber, and middle plunger rod just can stretch as required; Another root auxiliary connecting rod is then U-shaped design and in lower end, damping spring is housed; The stop up and down that piston runs stroke sets with the length of auxiliary connecting rod and bent axle brachium; When mixed oil and gas in auxiliary connecting rod drive piston compression cylinder is to cylinder charge burning expansion during DC ignition, pressure powerful on piston acts on two connecting rods, at this moment less the becoming by the shorter twisting resistance of the arm of force is comparatively large the surge pressure of bent axle of the auxiliary connected auxiliary crankpin angle of U-shaped connecting rod and damping spring is compressed, piston major part pressure is naturally loaded into and promotes mainly on hydraulic connecting rod, and the main crankshaft arm of force that it connects becomes with piston movement direction, and 60 degree of longer twisting resistance of the angle arm of force are little can pass to transmission system the pressure on piston completely; Magnetic switch when the main crankshaft arm of force turns over 120 degree in hydraulic connecting rod is touched and is made oil pressure valve open hydraulic oil be back to the pressure of accumulator connecting rod intermediolateral column stopper rod from pressure oil chamber to retract, power now on piston is loaded into again on auxiliary U-shaped connecting rod completely, just the auxiliary crankpin angle rotation that at this moment auxiliary U-shaped connecting rod connects diminishes at about the 70 degree longer twisting resistance of the arm of force and continues the pressure on piston to pass to transmission system, and continues to drive piston to complete exhaust, air-breathing, compression stroke; Promote mainly hydraulic connecting rod then to rotate with connected main crankshaft, its plunger rod energy free-extension now coordinates potential difference of the high end; And run to budc to compression stroke piston and close plunger rod by the hydraulic valve of Electromagnetic Control and can only stretch out elongated cooperation and connected main crankshaft arm and rotate; Two cover bent axles alternately complete the conversion of pressure like this.The feature of this kind of design is that the bent axle arm of force is in the longest interval when promoting mainly when hydraulic connecting rod promotes main crankshaft, and piston pressure is also maximum interval, and piston is with promoting mainly hydraulic connecting rod, and substantially point-blank piston is also very little with the side pressure of cylinder wall; Therefore the engine power of this kind of design is enhanced about more than once than traditional single shaft generator.
Its suitable effect that has significantly improves engine power.
accompanying drawing explanation: Fig. 1 is the invention schematic diagram; Fig. 2 is three-dimensional structure diagram; Fig. 3 is that connecting rod is with wrist pin connection diagram.
In figure: 1 piston; 2 promote mainly hydraulic connecting rod; 3 main crankshafts; 4 auxiliary U-shaped connecting rods; 5 auxiliary bent axles; 6 wrist pins.
embodiment: piston 1 is inserted in from cylinder lower end, and the microcephaly promoting mainly the upper end of hydraulic connecting rod 2 is connected with the wrist pin 6 of piston, and the other end major part is connected with main crankshaft 3; The wrist pin 6 of the same also piston of microcephaly of auxiliary U-shaped connecting rod 4 upper end connects, and the other end major part is connected with auxiliary bent axle 5.
