Description
Technical field
The utility model relates to a kind of technical field of motor.
Background technique
Motor is the source of automobile power.Up to now, except electric vehicle few in number, motor car engine all is a heat energy power mechanism, is called for short hot machine.By the change of state of working medium, the heat energy that fuel combustion is produced is transformed into mechanical energy in hot machine.This motor is transformed into rotatablely moving of crank by connecting rod with the round straight line motion of piston, and then power is exported.In expansion stroke, the heat energy that motor produces fuel combustion is transformed into the mechanical energy that the promotion piston is done reciprocatory motion, drives bent axle by connecting rod again and rotates; In other strokes, come driven plunger reciprocating by crank again, thereby realize the process of ventilation and compression.
In the expansion stroke, the length of the acting arm of force L of piston action on crank changes along with the variation of crank angle θ.When piston during at top dead center, the center of piston, connecting rod and crankshaft main journal in line, at this moment the moment of torsion of bent axle is 0.The merit that gas pressure is done piston all is converted into " dead point " pressure to crankshaft main journal; And in other positions, the part of gas pressure makes piston produce lateral pressure, is exactly the pressure of countercylinder wall.This shows, conventional engines in the course of the work, the pressure that fuel combustion produces has only sub-fraction to be converted into the output torque of bent axle, and the overwhelming majority is converted into the pressure of piston countercylinder wall and to the pressure of crankshaft main journal, efficiency of energy utilization is not high.
In addition, in the work cycle of conventional engines, each parts institute bearing load all is periodically variable, makes to have produced uneven friction and bump (as engine knock, pull-cylinder phenomena) between each surface of contact, thereby influences the performance of motor.
The model utility content
The utility model purpose provides and a kind ofly can overcome to " dead point " pressure of main shaft and the lateral pressure of countercylinder wall the dynamic pressure guide rail support formula gear one tooth bar motor that energy utilization rate is high.
The utility model comprises the upper and lower casing of positioned opposite, upper and lower casing is arranged in parallel and is fixedly connected, two ends at upper and lower casing are provided with cylinder head respectively, be two cylinders of horizontal symmetrical distribution in the upper box, be two cylinders of horizontal symmetrical distribution in the lower box, a piston is housed respectively in each cylinder; Two pistons in the upper box are fixedly connected on the two ends of a piston push rod respectively, and described piston push rod is bearing on the dynamic pressure support guide rail that is arranged in the upper box, fixedly connected tooth bar on this piston push rod; Two pistons of lower box are fixedly connected on the two ends of another piston push rod respectively, and described piston push rod is bearing on the dynamic pressure support guide rail that is arranged in the lower box, fixedly connected tooth bar on this piston push rod; Between upper and lower casing, support two take-off (propeller) shafts that are parallel to each other respectively, on two take-off (propeller) shafts, arrange two gears respectively by bearing; The flank of tooth of above-mentioned two toothed rack relatively and be arranged in parallel, two toothed rack respectively with two gear engagement; Two gears respectively by two groups of folk prescriptions to control mechanism and two concentric connections of transmission output shaft, and described two groups of folk prescriptions are opposite to the transmission direction of control mechanism, fixedly connected intermeshing driving gear respectively on two transmission output shafts.
Working principle of the present utility model: form by casing, cylinder head, four cylinders and piston thereof, two piston push rods, two dynamic pressure slide guide mechanisms, double rack-bidentates wheel two-shipper structure, direction control mechanism and output shaft linking mechanisms etc.Wherein, upper and lower casing promptly is a cylinder block, and cylinder head is used for sealing and the formation gas distribution system, thereby forms the firing chamber.Two pistons in the same casing are connected to one by the corresponding piston push rod, constitute two cylinder drive units, and upper and lower casing constitutes the four cylinder four-stroke device of motor; Be meshed with two gears that are sandwiched between two tooth bars simultaneously, constitute double rack-bidentate wheel mechanism, can only transmit rotatablely moving of a direction by each folk prescription to control mechanism, two folk prescriptions export two gears to by each take-off (propeller) shaft respectively to the power of control mechanism, and two gears are meshing with each other and constitute the output shaft linking mechanism.The utility model utilizes pinion and rack, and by mutual engagement, the oscillating rectilinear motion that cylinder piston is driven tooth bar is transformed into a kind of reciprocating internal combustion engine that rotatablely moves of gear.
Working principle of the present utility model: the combustible gas blast produces huge positive pressure, the positive pressure that a certain cylinder produces passes to piston push rod by piston, order about tooth bar and do oscillating rectilinear motion, because two tooth bars are meshed with gear on two take-off (propeller) shafts simultaneously, so just can pass to two take-off (propeller) shafts to the positive pressure of the generation of exploding by double rack-bidentate wheel mechanism and folk prescription to control mechanism.Because two take-off (propeller) shafts are by the identical output shaft rotating speed linking mechanisms such as gear engagement formation of parameter, so whichsoever cylinder all can be finished by the conversion that rotatablely moves continuously to two take-off (propeller) shafts of the oscillating rectilinear motion of tooth bar in working stroke.
So, the utlity model has following two big superiority:
1,,, overcome " dead point " pressure of main shaft and the lateral pressure of countercylinder wall so cylinder almost completely is delivered to output shaft to the thrust institute work that piston produces because of rack and pinion is in plumbness in the course of the work all the time; Eliminated conventional engines in work cycle, each parts is because of cycle live load effect, makes inhomogeneous friction and bump (as engine knock, the scuffing of cylinder bore) phenomenon that produces between each surface of contact, thereby makes the efficient of motor reach maximum, and dynamic and static state performance is preferable.
2, adopt pinion and rack just to make in expansion stroke, mixed gas blast and the positive pressure that acts on piston head need not secondary and decompose, but the almost equivalent double rack-bidentate wheel drive mechanism that passes through drives the take-off (propeller) shaft rotation, reduce idle work, and then improve motor ground working efficiency, energy utilization rate height to greatest extent.
For upper and lower casing is cooled off, the utility model also is provided with the water jacket of recirculated cooling water respectively in upper and lower casing.
