Abstract
The utility model relates to an air distribution changing phase automatic controller for an engine. The utility model is composed of rocker arms, a rocker shaft, hydraulic plungers, an oil passage, etc., wherein, the upper side of the rocker shaft is provided with the common rocker arm 3 and the high-speed rocker arm 4; a valve gap can be regulated by the hydraulic plunger 6 which is arranged on the common rocker arm 3 through a one-way valve. The utility model is characterized in that the motor oil causes the hydraulic plunger 5 which is arranged on the high-speed rocker arm 4 to be butted with the blocking surface of the common rocker arm 3 through a pressure control one-way valve 8, which causes the high-speed rocker arm 4 to be contacted with a cam 2. When the speed is low, the high-speed rocker arm 4 is pulled up by a spring piece 10. Because the engine has no instant impact, the service life of the engine can be extended. The number of the valve can be regulated automatically according to the requirement, which causes the fuel of the engine to be saved.
Description
The utility model relates to motor and becomes port timing automatic control mechanism.
Disclose a kind of variable valve timing mechanism of motor on 1997 the 10th phases " automobile journal ", formed by common rocking arm, intermediate rockers, hydraulic piston and spacing piston etc., when time of engine low speed, common rocking arm work; When high engine speeds turned round, hydraulic mechanism stressed on hydraulic piston by hydraulic circuit, and intermediate rockers and common rocking arm are connected as a single entity, and this moment, valve was driven by High speed cam.This mechanism has rigid small size seriously to collide in the moment that intermediate rockers connects with common rocking arm, and operating conditions is bad, and in long-term operation process, the noise of motor is big, is easy to the component that wear and tear.
The purpose of this utility model is to provide the mechanism that can be under motor smooth working situation can automatically controlled engine becomes port timing.
For achieving the above object, the utility model has adopted following mode: motor becomes port timing automatic control mechanism, form by rocking arm, pitman arm shaft, hydraulic plunger, oil duct etc.; common rocking arm 3 and high speed rocker arm 4 are arranged on the pitman arm shaft 11; hydraulic plunger 6 on the common rocking arm 3 is regulated the valve clearance by one-way valve 9; it is characterized in that machine oil makes the block face of the common rocking arm 3 in hydraulic plunger 5 straight tops on the high speed rocker arm 4 by pressure control one-way valve 8; high speed rocker arm 4 is contacted with cam 2, and high speed rocker arm 4 is by spring sheet 10 pull-ups during low speed.
The utility model is to have utilized two kinds of hydraulic plungers change port timing of control motor under high speed and low speed respectively, thereby make engine mildness, because no moment collides, prolonged the working life of motor, when the valve number of motor increases, the number that only needs to increase high-speed hydraulic plunger 5 and hydraulic plunger 6 gets final product, and this structure makes the fuel-economy of motor, and has improved widely the working life of motor.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is that every cylinder two valves of the present utility model become the port timing mechanism map;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the partial view of Fig. 1;
Fig. 4 is the A-A face sectional view of Fig. 3;
Fig. 5 is the B-B face sectional view of Fig. 1;
Fig. 6 is that every cylinder four valves of the utility model become the port timing mechanism map;
Fig. 7 is that four valves of control valve opening quantity automatically become the port timing mechanism map.
Example 1: as Fig. 1 to Figure 5 shows that every cylinder two valves become the port timing mechanism map, motor becomes port timing automatic control mechanism, by rocking arm; pitman arm shaft; hydraulic plunger; compositions such as oil ducts; common rocking arm 3 and high speed rocker arm 4 are arranged on the pitman arm shaft 11; hydraulic plunger on the common rocking arm 36 is regulated valve clearancies by one-way valve 9; machine oil makes the block faces of the common rocking arm 3 in hydraulic plunger 5 straight tops on the high speed rocker arm 4 by pressure control one-way valve 8; high speed rocker arm 4 contact; high speed rocker arm 4 is by spring sheet 10 pull-ups during low speed; when time of engine low speed with cam 2; cam 1 control rocking arm 3 drives the valve work by hydraulic plunger 6; hydraulic plunger 6 can be regulated the valve clearance automatically by one-way valve 9; high speed rocker arm 4 is tightened up shell fragment 10 pull-ups, and the working surface of high speed rocker arm 4 leaves High speed cam 2, so high speed rocker arm 4 moves with rocking arm but do not work; When high engine speeds turns round, engine oil pressure raises, machine oil backs down pressure control one-way valve 8 and promotes the pulling force that high-speed hydraulic plungers 5 overcome tension shell fragment 10 high speed rocker arm 4 is contacted with the working surface of cam 2, High speed cam 2 drives high speed rocker arm 4 participation work, and the port timing that adapts to the high engine speeds running produces.
Example 2: every cylinder four valves as shown in Figure 6 become the working principle of port timing mechanism with embodiment 1, because of controlling two valves simultaneously, so many cams 1 and rocking arm 3 and corresponding high-speed hydraulic plunger 5 and hydraulic plunger 6.
Example 3: as shown in Figure 7; pitman arm shaft 11 has a common rocking arm 3 and high speed rocker arm 4; but have two high-speed hydraulic pistons 5 on the high speed rocker arm 4; cam 1 drives rocking arm 3 work during low speed; high speed rocker arm 4 is tightened up shell fragment 10 pull-ups and does not contact with High speed cam 2; so do not work; another rocking arm 3 does not have cam not work yet; just two intake valves have only an intake valve job; when high engine speeds is moving when changeing, engine oil pressure raises and backs down the pulling force that 8, two high-speed hydraulic plungers 5 of pressure control one-way valve overcome tension shell fragment 10; make the work of the working surface of high speed rocker arm 4 and cam 2 and contact; high speed rocker arm 4 drives 3 work of two rocking arms, makes two intake valve work, and port timing changes; two intake valve work simultaneously, and motor performance under low speed and fast state can both well be brought into play.So just overcome because during the four-valve engine low-speed running, gas flow rates is slow, it is undesirable to make that the gas that enters cylinder is easy to produce eddy current, and the power that influence motor is brought into play and shortcoming such as exhaust emissions.
