Abstract
The invention designs a connecting rod linkage resistance-reducing valve mechanism. A connecting rod mechanism is used for controlling an engine valve to move left and right in a cylinder to achieve on and off of the valve. Compared with existing engine valves, the connecting rod linkage resistance-reducing valve mechanism has the advantages that structure is simple, and overall high of an engine is decreased; transmission parts are simplified, and transmission efficiency is improved; impact noise in working of the engine is lowered; intake and exhaust resistance is reduced, and air exchange efficiency is improved; and valve wear is reduced, whole service life of a valve gear is prolonged, and working efficiency of the engine is improved.
Description
Technical field
What the present invention relates to is a kind of connecting rod slider coupled engine distribution device valve, belongs to automobile, mechanical engine structural design field.
Background technique
Explosive motor such as gasoline, diesel oil has been widely used in each engineering fields such as land communications, farm machinery, engineering machinery, ocean seagoing vessel, the ship of war, aviation power and power station.
At present, no matter be petrol engine or diesel engine, no matter be camshaft up-set type or camshaft down valve, by camshaft actuated, control the opening and closing of valve by tappet, push rod and rocking arm.The present distribution device form that extensively adopts, as shown in Figure 1, the following defective of its ubiquity:
1, the distance of driving mechanism or driving mechanism is far away, has reduced the motor transmission efficiency;
2, the component of rod category of distribution device is more, and mechanical shock is many, and each rod member of distribution device is subjected to mechanical shock fragile.
3, up-and-down motion type valve and valve seat impact wear cause gas leakage to lower efficiency than Da Yi, even cause valve wearing and tearing excessive and lost efficacy.
4, intake valve and exhaust valve all move up and down to control the switching of valve, and the up-and-down motion type valve has increased intake resistance and exhaust resistance, and intake and exhaust efficient is reduced.
The present invention has designed a kind of double-slider extracting and pushing type engine distribution device by theory and practice, not only make distribution device obtain simplifying, and can overcome the above-mentioned shortcoming of up-and-down motion type valve, improve the operating life of integral rigidity, transmission efficiency, intake and exhaust efficient and each part of distribution device of motor greatly, thereby improved efficiency of engine on the whole, reduced cost and breakdown in the motor rate.
Summary of the invention
The present invention adopts connecting rod slider connection driving mechanism, and as shown in Figure 2, camshaft 10 is driven by crankshaft timing gear; Connecting rod 13A end is hinged on the pull bar 12 (being equivalent to slide block 1 in the double-slider mechanism), the B end is hinged on the valve 14 (being equivalent to slide block 2 in the double-slider mechanism); Valve 14 is flat, is embedded in the cylinder block 15, and only does side-to-side movement.
When the cam 11 on the camshaft 10 moves to the basic circle profile and finishes to begin to rise, namely drive pull bar 12 and make progress moving linearly to the extreme higher position from extreme lower position.This moment, pull bar 12 drivening rod 13A end also made progress moving linearly to the extreme higher position by its extreme lower position, and connecting rod 13 is made small sway and can drive valve 14 by its B end hinge to move right ultra-Right position (valve is opened fully) from ultra-Left position (valve is closed fully).
In above-mentioned cam 11 uphill process, pull bar 12 makes progress moving linearly to the extreme higher position from extreme lower position, can finish the unlatching of valve by double-slider mechanism.
When cam 11 is finished uphill process and is begun to descend by peak, pull bar 12 drivening rod 13A end also by the downward moving linearly in its extreme higher position to extreme lower position, connecting rod 13 was made reverse small sway and can be held hinge drive valve 14 move to ultra-Left position (valve is closed fully) left from ultra-Right position (valve is opened fully) by its B this moment.
In above-mentioned cam 11 decline processes, pull bar 12 from the extreme higher position downward moving linearly can finish closing of valve to extreme lower position by double-slider mechanism.
Above-mentioned in cam 11 risings and two processes that descend, a work cycle namely having finished valve opening and closed.When cam 11 drops to minimum point, when its basic circle contacted with pull bar 12, pull bar 12 remained static, and connecting rod 13 also remains static, and valve 14 namely is in closed condition always.
In order to guarantee that valve 14 steadily opens, the right-hand member of valve 14 is done greatlyyer, makes valve no matter still be in closed condition opening, and its center of gravity all drops on the cylinder body on right side.
Connecting rod interlock drag reduction valve mechanism has following several obvious advantage with respect to existing engine valve:
1, simple in structure, reduced the whole height of motor;
2, reduce driving component, improved transmission efficiency;
3, reduce driving component, reduced the impact noise in the engine operation;
4, reduce air inlet and exhaust resistance, improved scavenging efficiency;
5, reduce the valve wearing and tearing, improved the bulk life time of distribution device.
