In internal-combustion engine, there are the shortcomings such as lifting curve that driving is impacted greatly, transmission is complicated, manufacturability is poor, be difficult for realizing ideal in traditional cam drive valve gear.Germany FEV motor company has adopted the electromagnetic air valve scheme, and the switching that plays valve is by electromagnetic valve, and this scheme has proposed high requirement to the response of solenoid valve, the manufacturing difficulty, and cost is higher.Chinese patent CN1250841A has proposed a kind of fluid power and has driven valve gear, and its each valve motion by a rotor control, needs a group rotor identical with cylinder number respectively, the structure more complicated, and volume is bigger, especially for all the more so on the multicylinder engine.
(3) summary of the invention
The utility model is exactly in order to solve above-mentioned the deficiencies in the prior art part, and a kind of hydraulic driver of internal combustion engine is provided, and can realize not having the soft drive of impact, obtains desirable lifting curve with easy processing method, and easy to process, and cost is low.
A kind of hydraulic driver of internal combustion engine described in the utility model, it is characterized in that, it is interconnected by distributor and actuating valve forms, wherein, distributor is by Moving plate, price fixing, the distributor cover, oil outlet tube, running shaft interconnects composition, Moving plate is fixed on the running shaft, rotate with certain rotating speed with running shaft, have oil inlet hole on the distributor cover, and be connected by the distribution of lubrication oil slotted eye that has on oil inlet hole and the Moving plate, have oil outlet on the price fixing, and be connected with oil outlet tube by oil outlet, extreme pressure lubricant enters distribution of lubrication oil slotted eye on the Moving plate by the oil inlet hole on the distributor cover, rotation along with distribution of lubrication oil slotted eye on the Moving plate, communicate with a plurality of oil outlets and oil outlet tube on the price fixing successively, oil outlet tube is connected with the oil inlet hole of actuating valve, with realize at regular time and quantity to the actuating valve fuel feeding; Actuating valve is interconnected by actuating valve guiding valve and guide to be formed, the actuating valve guiding valve is fixed in the guide by return spring and jump ring, guide has oil inlet hole and exhaust/oil drainage hole, can fixedly connected spring-leaf retainer between return spring and jump ring, the actuating valve guiding valve is done straight line motion in guide, return spring is a guiding valve return usefulness, and jump ring is used for the location.
In order to realize the utility model better, between the oil inlet hole of the oil outlet tube of distributor and actuating valve, one-way valve can be installed.
The utility model compared with prior art, have following advantage and beneficial effect: the utility model is after being used for internal-combustion engine, can make the internal combustion engine drive device realize not having the soft drive of impact, can obtain the lift rule that satisfied cam drive mode is difficult for accomplishing with easy processing method, non-lateral pressure, the element installation position is flexible, size is little, simple in structure, easy to process, be easy to automatically controlledization.The utility model is applicable to that also other needs valve to realize the machinery of proper functioning.
(4) description of drawings
Fig. 1 is a workflow diagram of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a price fixing structural representation of the present utility model;
Fig. 4 is a Moving plate structural representation of the present utility model.
(5) embodiment
As shown in Figure 1, concrete working procedure of the present utility model is: 1. machine oil is sent into accumulator by motor-drive pump (during starting) or oil pump (during proper functioning) pressurization; 2. the high-pressure oil of pressure stability enters distributor in the accumulator, by mechanically operated timing allocation device, at the actuating valve of determining constantly high-pressure oil to be sent to corresponding to a certain cylinder valve, and continues the definite time; 3. actuating valve overcomes the suffered gas pressure of spring force and valve under the oil pressure effect, drives valve event according to certain rules, thereby realizes the switching on time of valve.Between distributor and actuating valve one-way valve is installed, high-pressure oil refluxes, the pressure loss is excessive and reduce system acting lags behind to avoid.The machine oil that accumulator, actuating valve etc. are located to overflow flows back to sump voluntarily.
Be depicted as the scheme that the utility model is used for 6 cylinder IC engines as Fig. 2,3,4.Moving plate 3 is fixed on the running shaft 6, has oil inlet hole 5 on the distributor cover 4, and is connected by the distribution of lubrication oil slotted eye 8 that has on oil inlet hole 5 and the Moving plate 3, has oil outlet 7 on the price fixing 2, and is connected with oil outlet tube 1; Actuating valve guiding valve 11 is fixed in the guide 12 by return spring 13 and jump ring 15, and guide 12 has oil inlet hole 10 and exhaust/oil drainage hole 9, connects spring-leaf retainer 14 between spring 13 and the jump ring 15; Between the oil inlet hole 10 of the oil outlet tube 1 of distributor and actuating valve, one-way valve is installed.Fig. 4 arrow is depicted as fuel feeding and continues the angle.The every cylinder of internal-combustion engine has an intake valve and exhaust valve.A distributor is used to control 6 intake valves of 6 cylinders, and another distributor is used to control 6 exhaust valves of 6 cylinders.Oil outlet 7 apertures on the distributor price fixing 2 are 5mm, and angle is 15 degree.For 6 cylinder machines, be 240 Shaft angles of writing music as the valve opening delivery angle, each cylinder working of motor is spaced apart 120 degree, and distribution of lubrication oil slotted eye 8 angles are 105 degree on the distributor Moving plate 3; Actuating valve guiding valve 11 diameters are 25mm, and oil inlet hole 10 diameters are 10mm, exhaust/oil drainage hole 9 that to have 3 diameters be 1mm, guiding valve active force 44kg, maximum oil mass 78L/h, maximum oil pressure 4.5Mpa; Accumulator volume is 15.9L; Motor-drive pump fuel delivery 10L/min; The one-way valve cracking pressure is got 0.37Mpa.Former internal-combustion engine uses the cam drive valve, the processing technology complexity, and be difficult to obtain satisfied lift rule, physical dimension is bigger, and automatically controlledization is inconvenient.After using the utility model, can realize not having the soft drive of impact, process easyly, can obtain satisfied lift rule, non-lateral pressure, the element installation position is flexible, and size is little, and automatically controlledization is conveniently.As mentioned above, can realize the utility model preferably.
Shown in Fig. 2,3,4, also another program can be arranged, each valve that promptly uses a distributor to control whole cylinders opens and closes.For one 3 cylinder IC engine, if any 3 intake valves and 3 exhaust valves, use distributor of the present invention, 6 oilholes drive 3 intake valves and 3 exhaust valves respectively on the distributor.Only use a distributor, can realize that each valve of controlling whole cylinders opens and closes.As mentioned above, can realize the utility model preferably.
