Abstract
The invention relates to the technical field of motorcar engines, in particular to a hydraulic transmission air distribution system of a motorcar engine. In the system, a left hydraulic cylinder and a right hydraulic cylinder are arranged in a cylinder head cover of a motorcar; piston rods of the left hydraulic cylinder and the right hydraulic cylinder are connected with an intake valve and an exhaust valve respectively; a high-pressure oil pump is arranged on a crank case at the same time; and a driving gear used for driving the high-pressure oil pump and a timing control valve used for controlling the opening and closing of the intake valve and the exhaust valve are arranged on a rotary shaft of the crank shaft. Thus the air distribution system of the motorcar engine is changed to a hydraulic transmission way from the original mechanical transmission way. The expansion of the left and right piston rods realizes the opening and closing of the intake valve and the exhaust valve. Vulnerable mechanical components, such as a timing chain, a camshaft, a rocker arm and the like, are eliminated from a petrol engine, so that phenomena of mechanical wear and frictional noise disappear without the mechanical components; and thus the occurrence rate of malfunctions is reduced, the service life of the petrol engine is prolonged, the working performances of the engine is improved and the noise of the engine is also reduced.

Engine start, bent axle 9 rotates, and drives actuation gear 11 and rotates; Actuation gear 11 drives high pressure oil pump 22 work through driving gear 10, and high pressure oil pump 22 extracts fluid in crankcase 14, flow to left hydraulic cylinder 2 and right oil hydraulic cylinder 21 respectively through left oil inlet pipe 25 and right oil inlet pipe 7 after the supercharging; Bent axle 9 drive actuation gear 11 also drive driving gear 13 when rotating and rotate, driving gear 13 with correct time control panel 8 be meshing with each other, so correct time, control panel 8 rotated; The switching of the oil outlet of control panel 8 rotation in correct time control left bank oil pipe 16 and right oil exit pipe 15, when the oil outlet of left bank oil pipe 16 was communicated with outer channel 24, the oil outlet of left bank oil pipe 16 was opened; When the oil outlet of left bank oil pipe 16 was not communicated with outer channel 24, the oil outlet of left bank oil pipe 16 was closed, promptly when correct time be not provided with on the control panel 8 groove card and left bank oil pipe 16 oil outlet at once; The oil outlet of left bank oil pipe 16 is closed; Correct time this moment, control panel 8 sealed the oil outlet of left bank oil pipe 16, in like manner, and when the oil outlet of right oil exit pipe 15 is communicated with internal channel 23; The oil outlet of right oil exit pipe 15 is opened; When the oil outlet of right oil exit pipe 15 was not communicated with internal channel 23, the oil outlet of right oil exit pipe 15 was closed, promptly when correct time be not provided with on the control panel 8 groove card and right oil exit pipe 15 oil outlet at once; The oil outlet of right oil exit pipe 15 is closed, and correct time this moment, control panel 8 sealed the oil outlet of right oil exit pipe 15.
When bent axle 9 rotated counterclockwise, correct time, control panel 8 clockwise rotated, when correct time control panel 8 turn to just oil outlet with left bank oil pipe 16 when sealing up; Be designated as 0 ° of position this moment, when correct time control panel 8 from 0 ° to the process of 90 ° of rotations, left piston bar 4 is under the pressure effect of fluid; Move down, stretch out left hydraulic cylinder 2, thereby intake valve 5 is opened; Air gets into piston cylinder, and piston 6 moves downward, at this moment; The oil outlet of right oil exit pipe 15 is in open mode all the time, gets into the fluid of right oil hydraulic cylinder 21, from the oil outlet of right oil hydraulic cylinder 21 through oil exit pipe; Flow back in the crankcase 14 from the oil outlet of right oil exit pipe 15, therefore, exhaust valve 18 cuts out all the time in this process.
When correct time control panel 8 from 90 ° to 180 ° of rotating process, the oil outlet of left bank oil pipe 16 is opened, fluid flows in the crankcase 14 from the oil outlet of left bank oil pipe 16; At this moment, left piston bar 4 resets under the effect of left spring 3, thereby intake valve 5 is closed; Piston 6 moves upward; Pressurized air, and the oil outlet of right oil exit pipe 15 still is in open mode, exhaust valve 18 still is in closed condition.
When correct time control panel 8 from 180 ° to 270 ° of rotating process, the oil outlet of the oil outlet of left bank oil pipe 16 and right oil exit pipe 15 all is in open mode, intake valve 5 and exhaust valve 18 all are in closed condition, at this moment, piston 6 moves downward.
When correct time control panel 8 from 270 ° to 360 ° of rotating process, correct time control panel 8 with the sealing of the oil outlet of right oil exit pipe 15, right piston rod 19 is under the pressure effect of fluid; Move down, stretch out right oil hydraulic cylinder 21, thereby exhaust valve 18 is opened; Waste gas in the piston cylinder is discharged, and piston 6 moves upward, at this moment; The oil outlet of left bank oil pipe 16 is in open mode all the time, gets into the fluid of left hydraulic cylinder 2, from the oil outlet of left hydraulic cylinder 2 through oil exit pipe; Flow back in the crankcase 14 from the oil outlet of left bank oil pipe 16, therefore, intake valve 5 is closed all the time in this process.
So far, correct time, control panel 8 turned over 360 °, and motor has been accomplished the one action circulation; Since driving gear 13 with correct time control panel 8 gear ratio be 1:2; Therefore its velocity ratio is 2:1, and promptly control panel 8 rotations in correct time one all driving gears 13 rotated for two weeks, therefore; This moment, driving gear 13 rotated for two weeks, and promptly bent axle 9 rotated for two weeks.
The oil outlet of the oil outlet of left bank oil pipe 16 and right oil exit pipe 15 is to occur with the form of often opening in the foregoing description, and when promptly the oil outlet of left bank oil pipe 16 was opened, intake valve 5 was closed, and when the oil outlet of left bank oil pipe 16 was closed, intake valve 5 was opened; When the oil outlet of right oil exit pipe 15 was opened, exhaust valve 18 cut out, and when the oil outlet of right oil exit pipe 15 was closed, exhaust valve 18 was opened.In the actual fabrication process, can be to occur also with the oil outlet of left bank oil pipe 16 and the oil outlet of right oil exit pipe 15 with normally closed form, when promptly the oil outlet of left bank oil pipe 16 was closed, intake valve 5 was closed, and when the oil outlet of left bank oil pipe 16 was opened, intake valve 5 was opened; When the oil outlet of right oil exit pipe 15 was closed, exhaust valve 18 cut out, and when the oil outlet of right oil exit pipe 15 was opened, exhaust valve 18 was opened, and also will change the structural type of left and right sides oil hydraulic cylinder accordingly.
Be noted that; The above embodiment is to the explanation of technological scheme of the present invention and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to existing technology; As long as do not exceed the thinking and the scope of technological scheme of the present invention, all should be included within the interest field of the presently claimed invention.
