Abstract
The invention provides a horizontal opposed engine adopting a novel technical scheme by aiming at the technical defects of a traditional engine in the prior art. The horizontal opposed engine has the advantages that the engine motive power output smoothness can be improved, the engine gravity center can be lowered, and the vehicle economic performance can be improved. The horizontal opposed engine adopts a horizontal opposed air cylinder structure, a transmission assembly of a spiral straight shaft rod, a shaft sleeve and a one-way clutch is added between a piston and a connecting rod on the basis of a connecting rod, a crank mechanism and a crank shaft assembly of the traditional engine, so motive power generated by linear movement work application of the piston in each time can be transmitted to the crank shaft to be output through the connecting rod and the crank like the traditional engine, and can also be transmitted to the crank shaft to be output in a way of maintaining the motive power acting radius being 90 degrees through a spiral straight shaft rod, a shaft sleeve and the one-way clutch in the 90-degree direction.
Description
Technical field:
The present invention relates to a kind of motor car engine, particularly a kind of explosive motor of flat opposed air cylinder structure, belongs to combustion engine technical field.
Background technique:
Orthodox car motor is generally four-stroke internal-combustion engine, adopts the form of array or V-type layout arrangement, and its rotator inertia amount is larger, and rotating speed is restricted, and power is difficult to improve; Due to the non-symmetry structure of each cylinder, its balance is poor, and the vibrations of generation are also larger.In addition, traditional on-board engine also exists volume large, and the drawback that center of gravity is high is unfavorable for the stability of car load very much, also makes the moulding of whole car body be difficult to mate with air dynamic behaviour.
Conventional engines piston is by connecting rod, power to be passed on bent axle, only has when connecting rod becomes 90 to spend with the action radius angle of bent axle, and piston is maximum to the opplied moment of bent axle, thereby the power of exporting is just maximum.Due to, bent axle is in continuous rotation, the action radius angle of connecting rod and bent axle is in continuous variation, so piston can lose a part to bent axle institute work by the variation because of angle, and motor is because the defect of this body structure will not reach its due optimum efficiency like this.
Summary of the invention:
The object of the invention is to for prior art drawback, a kind of new technological scheme is provided, be a kind of smoothness that can improve engine power output, reduce motor center of gravity, improve the pancake engine of vehicle economy.
The present invention is that technological scheme as described below realizes:
A kind of pancake engine, its specialization of described motor is: its cylinder setting is flat opposed, piston in described horizontally-opposed cylinder is all fixedly equipped with a spiral d-axis bar, by connecting connecting rod, crank and bent axle, become one, on described bent axle, be fixedly installed a large bevel gear.
Above-mentioned pancake engine is provided with axle sleeve on each root spiral d-axis bar, in the spiral chute of keying in piston spiral d-axis bar, makes it to become one by the card tip by the tip hole on axle sleeve, and described axle sleeve can be by card tip slip rotation.
Above-mentioned pancake engine, is fixedly installed overrunning clutch gear on axle sleeve, described axle sleeve is fixed on the engine housing of motor by bearing.
Above-mentioned pancake engine, overrunning clutch gear often meshes with transmitting gear, transmits gear and is connected in one by bevel pinion fixing on passing shaft and axle, and the large bevel gear on described bevel pinion and bent axle often meshes.
Above-mentioned pancake engine, at the top of cylinder, be provided with intake valve with and exhaust valve, described exhaust valve and intake valve are all controlled its open and-shut mode by the cam assembly of motor.
Above-mentioned pancake engine arranges cooling chamber on the sidewall of cylinder, the liquid container pipeline connection of the radiation system of described cooling chamber and motor.
The present invention adopts flat opposed air cylinder structure, connecting rod at conventional engines, on crank mechanism and crankshaft group, a spiral d-axis bar and axle sleeve between piston and connecting rod, have been increased, overrunning clutch gear, transmit gear, passing shaft, bevel pinion with and the transmitting assemblies of bent axle large bevel gear, the power that piston linear motion acting is produced can pass through connecting rod as traditional motor, crank is passed to bent axle output, can pass through spiral d-axis bar again, the transmitting assemblies of axle sleeve and overrunning clutch gear, make the action radius of power drive to bent axle output with 90 degree.Both the power that acting produces each time of piston, was delivered to bent axle and was exported by connecting rod, crank by spiral d-axis bar; Meanwhile, with the direction of 90 degree, by spiral d-axis bar, axle sleeve and overrunning clutch gear assembly, being delivered to bent axle again exports.The acting each time of piston make power by both direction simultaneously to bent axle transmission.
In addition, in the present invention and conventional engines structure, just increase a piston spiral d-axis bar and axle sleeve, overrunning clutch gear, transmitted the transmitting assemblies of gear, bevel pinion and bent axle large bevel gear, in its structure of comparing, do not seem more complicated, on manufacturing, can't cause larger difficulty.
The present invention, for the structural improvement of conventional engines, has not only improved the output smoothness of motor, improve the economic performance of vehicle, and the structure of flat opposed cylinder is convenient to the layout of car load, is conducive to mating of car body moulding and air dynamic behaviour.
