The utility model is described in detail as follows below in conjunction with drawings and Examples:
It is made up of a two-way cylinder (1), a main piston (2), two cover distribution devices, four connecting rods (3), two oil drums (4,5), oil circuit (6), a starter concurrently engine (7), two oil hydraulic motors (8,25), a coasting valve (9) and a brake valve (10).As shown in Figure 1, two-way cylinder is positioned at the middle part of motor, two cover distribution device, four connecting rods and two oil drums are installed to its bilateral symmetry, the both sides of two-way cylinder all provide working space, the motion of main piston in two-way cylinder has compression and two strokes of work done, and the compression stroke on main piston one side in two-way cylinder relies on another side expansion space stroke and piston its own inertial to realize.When two-way cylinder working space on one side carried out compression stroke, the working space of another side carried out expansion space stroke, and two work cells are carried out different strokes and mutual alternative simultaneously, realize the to-and-fro motion of main piston thus.The to-and-fro motion of main piston produces the pressure difference of oil by piston (11) to-and-fro motion in the connecting rod drive oil drum, changes the oil pressure difference into power output by oil hydraulic motor.The right and left of main piston all with two-way cylinder in one side correspondingly form working space, main piston is made by heavy metal, makes itself to have certain weight, so that have certain inertia at the volley.The structure of two cover distribution devices is in full accord, it is installed in the both sides of two-way cylinder symmetrically, it comprises gas handling system, vent systems, emission control three parts, the pressure of gas handling system is improved by air compressor (12), vent systems is by electromagnetic coil (13), outlet valve (14), return spring (15) is formed, emission control is by the groove on the connecting rod (16), button spring (17), cooperatively interacting of connector (24) realizes, when main piston runs to suction port in expansion space stroke, emission control is closed circuit switch, connect electromagnetic coil circuit, producing electromagnetic force pushes exhaust valve open, combustion gas, when main piston runs to suction port in compression stroke, emission control disconnects circuit switch, cut off electromagnetic coil circuit, exhaust valve relies on the pulling force of return spring that exhaust valve is shut.Two oil drums are positioned at the both sides of two-way cylinder, covering of the two sides of each oil drum respectively has two one-way valves (18,19,20,21), there is a piston that joins with connecting rod that oil drum is divided into two chambeies (22,23) in the oil drum, when the piston motion in the connecting rod drive oil drum, rely on the effect of one-way valve, two chamber oil-feed and oil extractions respectively, and in oil circuit, produce pressure difference, make hydraulic difference change power output into by oil hydraulic motor.Whether coasting valve passes through oil hydraulic motor by the switch inside control oil channel, when coasting valve is in closed condition, oil circuit can not pass through oil hydraulic motor, at this moment ato unit under the situation of external resistance can not had, and in vehicle traveling process, cut off the power output of motor, car is slided.Brake valve changes the flow direction realization brake of the oil circuit that passes through oil hydraulic motor and the function of reversing by the valve switch of self.
Present embodiment is when work, at first open coasting valve, as shown in Figure 4, make matrix (28) forward the dotted line place to by the solid line place, oil is walked along dotted line, does not have being flow to oil circuit (30) and locked one-way valve (19,20) is opened by oil circuit (29) of resistance, advance by one-way valve (20), go out from one-way valve (19), as shown in Figure 1, one-way valve (18,21) still pins (starting working simultaneously in the both sides of two-way cylinder).Start starter (7) and make it to drive oil hydraulic motor (8), oil is flowed along the direction that oil circuit shown in Figure 1 flows to rapidly, at this moment one-way valve (18,21) locked, oil advances along one-way valve (20), oil in the chamber, a left side (23) goes out along one-way valve (19), form pressure difference about the oil drum piston, promote oil drum piston (11) to left movement, drive main piston (2) to left movement by connecting rod (3), when the left end limit of main piston arrives the suction port left side (the left dotted line among Fig. 1), as shown in Figure 3, groove in the connecting rod (16) leaves buckles spring (17), the button spring is become by following state go up strong attitude, button spring and connector (24) disconnect, electromagnetic coil (13) outage, do not produce electromagnetic force, exhaust valve (14) cuts out under the effect of return spring (15), when left dotted line is passed through in the left side of main piston, as shown in Figure 1, left side working space is closed, main piston continues under the band of oil drum piston (11) to left movement, the gas of left side working space is compressed, back (at this moment oil sprays into left working space by oil nozzle (26) at main piston during just by left dotted line) is finished in compression, spark plug (27) igniting, oil after the compression, air mixture become high pressure-temperature gas rapidly.When oil hydraulic motor (8) was activated device concurrently engine (7) drive, air compressor (12) was also driven, and was inflated in cylinder by the suction port at two-way cylinder middle part.After the compression stroke of left work cell was finished, when promptly the integral body of motor was in as shown in Figure 1 state, right active chamber began inflation, left active chamber igniting.Main piston moves right rapidly under the effect of high temperature and high pressure gas, when its right side reaches right dotted line, in right active chamber, the button spring is gone up the state exhaust valve by following state arrival and is shut, and suction port is sealed by main piston, gas begins to be compressed, the oil nozzle commencement of fuel injection.Main piston continues operation to the right when the left side arrives left dotted line, and in left active chamber, groove moves to button spring place, make the button spring arrive state down by last state, button spring and connector are connected, the electromagnetic coil energising, exhaust valve overcomes the pulling force of return spring and opens combustion gas under the repulsion of electromagnetic force.Main piston continues one section of operation under inertia, left working space and suction port are connected, and begins ventilation.At this moment, right working space repeats left working space action, so circulation, and the oil with pressure difference flows in oil circuit, changes hydraulic difference into power output by oil hydraulic motor (25).
The utility model is compared present technology and is had following advantage:
1, compact conformation, distribution is simple, working stability;
2, saved the clutch in the original system, speed changer, power transmission shaft etc., cost is low, and is easy to manufacture, and noise is little, and is in light weight;
But 3 units are solely opened, but also simultaneously operation of multimachine, and can realize the low speed large torque, and the little torque of high speed and high speed large torque so just can pass through at a high speed rough road, at a high speed climbing, and need be by not underspeeding to obtain high torque;
4, power-to-volume ratio is big, low-speed dynamic and good economy performance, and startability and durability are also fine;
5, help the interior space arrangement.
