Description
Technical field
The present invention relates to engine art, especially a kind of vibrator energy storage free piston engine.
Technical background
Free-piston engine is extremely paid attention in recent years because it is simple in structure, efficient is high.But " catching fire " problem of free-piston engine (being the problem that burning but takes place should burn in the firing chamber of free-piston engine the time) is to influence free-piston engine to be able to one of key issue of practical application.So be badly in need of a kind of new technology that can make the work of free-piston engine continous-stable of invention.
Summary of the invention
In order to address the above problem, the technological scheme that the present invention proposes is as follows:
A kind of vibrator energy storage free piston engine comprises free-piston, elastomer and oscillator, and described free-piston is connected with described elastomer, and described elastomer is connected with described oscillator.
Between described free-piston and described elastomer, establish fork, described free-piston is rotationally connected through an end of rotatingshaft and described fork, the other end of described fork is connected with described oscillator through described elastomer, on described fork, establish the bearing pin slide opening, described fork is rotationally connected through described bearing pin slide opening and pin slide, and described bearing pin is connected with body.
Described bearing pin is made as and the body formula that is connected, or is connected with body through distance adjusting system, and described distance adjusting system is by the distance between the center line of control requirements described bearing pin of adjustment and described free-piston.
Between described free-piston and described elastomer, establish tooth bar, gear and fork, described free-piston is connected with described tooth bar, described rack and pinion engagement, described gear is connected with described fork, described fork is connected with described elastomer, circle centre position in described gear on described fork is established bearing pin, and described fork and described bearing pin are rotationally connected, and described bearing pin is connected with body.
Establish flexible regulating mechanism between described fork and described elastomer, described flexible regulating mechanism is made as mechanical type, electrodynamic type or hydraulic type, and described flexible regulating mechanism is adjusted the distance between described oscillator and the described bearing pin.
A kind of vibrator energy storage free piston engine, comprise free-piston, fork and oscillator, described free-piston is rotationally connected through an end of rotatingshaft and fork, the other end of described fork is connected with described oscillator, on described fork, establish the bearing pin slide opening, described fork is rotationally connected through described bearing pin slide opening and described pin slide, and described bearing pin is connected with body;
Or described free-piston is connected with tooth bar, described rack and pinion engagement, and described gear is connected with described fork, and described fork is connected with described oscillator, and the circle centre position in described gear on described fork is established bearing pin, and described fork and described bearing pin are rotationally connected.
Establish flexible regulating mechanism between described fork and described oscillator, described flexible regulating mechanism is made as mechanical type, electrodynamic type or hydraulic type, and described flexible regulating mechanism is adjusted the distance between described oscillator and the described bearing pin.
Conventional engines why can stable operation, be because the setting of flywheel and/or the setting of multi-cylinder, make when piston remains static, the mass motion system of motor does not still stop, be that mass motion system each time point in the entire work process of motor of motor all has enough energy and overcomes the particularly resistance during compression stroke of any one piston or a plurality of piston one-stroke in office, thereby guarantee the proper functioning of motor.And free-piston engine is just different, and when piston is in utmost point harmonic motion speed or state of rest when being near top dead center or the lower dead center (most cases be piston), the whole moving system of free-piston engine also is in utmost point harmonic motion speed or state of rest.That is to say that the stored energy of free-piston engine this moment is minimum even be zero, do not keep the required resistance that overcomes of piston motion rule so there are enough energy to overcome, therefore, cause " catching fire " state, influence the proper functioning of free-piston engine.Yet, increase the quality of free-piston merely, can make free-piston engine produce strong vibration.The present invention is by oscillator and elastomeric setting, make motor in running, part energy still is stored in the elastomer, no matter how low the speed of free-piston engine be in state, even state of rest, the energy that is stored in the elastomer can both overcome operating resistance, helps the motion of free-piston engine continous-stable, and then realizes the smooth running of free-piston engine.In the present invention, in not establishing elastomeric structure, because the setting of fork and bearing pin, make that the moving direction of the moving direction of piston and oscillator is opposite,, can alleviate the high vibration of free-piston engine simultaneously again so can increase energy stored.
So-called distance adjusting system can be mechanical type, electrodynamic type or hydraulic type among the present invention.Its effect is the distance of adjusting between bearing pin and the free-piston center line, to be implemented under the certain situation of piston stroke, adjust the swing speed and the angle of fork, and then the interior energy of elastomer what change is stored in, free-piston can be worked under different speed, and promptly free-piston engine is realized load responding (just being equivalent to conventional engines works) under different rotating speeds.
The so-called flexible regulating mechanism of the present invention also can be mechanical type, electrodynamic type or hydraulic type.It is used for adjusting the distance between oscillator and the bearing pin, reaches the purpose of adjusting oscillator swing speed and pendulum angle, and then adjusts and be stored in the elastomer and what of the energy in the oscillator, realizes that equally free-piston engine realizes load responding.
Beneficial effect of the present invention is as follows:
1, because the setting of elastomer, fork and oscillator can realize the operation of free-piston engine continous-stable.
2, owing to the setting of elastomer and oscillator, the vibration and noise in the time of can alleviating the free-piston engine operation is realized the smooth running of free-piston engine.
