The valve rocker arm device with improved structure are provided on a cylinder head and the two ends of the middle valve rocker arms of the valve rocker arm device can communicate respectively with a push bar and a air door. The air door rocker arm device also includes a base seat provided with a support and fixedly connected on the cylinder head. The middle portion of the air door rocker arm is articulated on the support. The structure makes the air door rocker arm sway around the articulation position of the air door rocker arm and the support on the cylinder head, thereby achieving the effect of control the on-off of the cylinder air door. The valve rocker arm device with improved structure has the characteristics of high stability, strong connection, convenient installment and long life time.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of structure improved Valve Rocker Organization on the petrol engine.
Background technique
Valve Rocker Organization is an indispensable important mechanism in the petrol engine, by the switching of valve in its control cylinder head.For example, petrol engine four strokes in the course of the work: air inlet, compression, outburst, exhaust, by Valve Rocker Organization action valve is opened during air inlet, during compression by Valve Rocker Organization with valve-closing.Then, by ignite oil gas and make its outburst of igniter, the waste gas after outburst is burnt cylinder combustion is later discharged behind the Piston Compression oil gas in the cylinder.As can be seen, Valve Rocker Organization plays important effect in said process.
In actual application, in order to guarantee the service behaviour of Valve Rocker Organization, people have passed through long term studies and exploration has proposed various schemes, provide a kind of small size universal petrol engine valve swing arm directional working mechanism as Chinese patent 200410085822.0, it is made up of adjusting screw rod, adjustment nut, valve rocker, guide block, valve clearance adjustment nut etc.Above-mentioned patent is connected adjusting screw rod on the cylinder head, utilize guide block and valve clearance adjusting nut to make it have the function of regulating the valve clearance, that is to say, the guide block that is provided with between valve rocker and the clearance adjusting nut can circumferentially not rotated guide block around adjusting nut by circumferential spacing on adjusting screw rod.Simultaneously, the shape of the bottom of guide block and valve rocker groove is complementary, and valve rocker just can not be swung like this.
After said mechanism was installed in cylinder head, the upper end of valve actuating push rod withstood on an end of valve rocker, and the other end of valve rocker can be pressed on the valve of petrol engine.When valve actuating push rod up pushed away, the other end of valve rocker pressed down the valve afterbody, opens valve.When valve actuating push rod moves down, put valve-closing on the other end of valve rocker.Reach the purpose that the control valve opens and closes by said process.But this mechanism is screwed onto entire mechanism on the cylinder head by single adjusting screw rod, and its soundness of such Placement is not high, and installment work is very not convenient yet.Simultaneously, valve rocker all exists the defective that wall is thin, intensity is not high by being stamped to form by the part that is stamped to form in the above-mentioned mechanism, and obviously, this valve rocker intensity is not high, and working life is shorter.
Summary of the invention
The purpose of this utility model is at the existing the problems referred to above of existing Valve Rocker Organization, provides a kind of working stability structure improved Valve Rocker Organization reliable, easy for installation and simple in structure.
The purpose of this utility model can realize by following technical proposal: a kind of structure improved Valve Rocker Organization, it is arranged on the cylinder head, the two ends of valve rocker can contact with valve stem with push rod respectively in the Valve Rocker Organization, it is characterized in that, described Valve Rocker Organization also comprises a base that is provided with support, base is connected on the cylinder head, and the middle part of above-mentioned valve rocker is hinged on the support.
Valve rocker in this structure improved valve rocker is hinged on the support, and support is connected on the base.Simultaneously, base is connected on the cylinder head again.Obviously, make that by such structure valve rocker can be around the hinged place swing of it and support on cylinder head.Particularly, push rod moves up and down this end swing that valve rocker is contacted with push rod, and the other end of valve rocker is also being followed swing and this end promotes valve stem in swing process, reaches the purpose that valve opens and closes on the control cylinder by moving up and down of valve stem.
In above-mentioned structure improved Valve Rocker Organization, described base is provided with at least two spacing holes and at least two fixed holes, and the bearing pin that is connected with cylinder head is arranged in the above-mentioned spacing hole, and the connecting end of screw passes fixed hole and is screwed onto on the cylinder head.Bearing pin is located in the spacing hole base is played position-limiting action, simultaneously, also can play the effect of location to base in installation process.In addition, screw passes fixed hole and is screwed onto on the cylinder head, makes that base is connected on the cylinder head firmly.
In above-mentioned structure improved Valve Rocker Organization, described valve rocker is an integral structure, forms by forging.Such structure is made more convenient, makes valve rocker have enough intensity simultaneously.
In above-mentioned structure improved Valve Rocker Organization, described valve rocker is two, and described support is " mountain " shape, and two above-mentioned valve rockers lay respectively at two gaps of " mountain " shape of support.
In above-mentioned structure improved Valve Rocker Organization, described base and support are integral structure.
Compared with prior art, this structure improved Valve Rocker Organization is hinged on valve rocker on the cylinder head by base, because base and cylinder head are to be connected with bearing pin that cylinder head is connected with two by two screws, that is to say that base and cylinder head have four joints.As can be seen, not only connective stability is higher for it, makes that the mechanical strength of this mechanism is higher, and it cooperates the purpose that reaches the location by bearing pin with spacing hole, makes the easier connection of screw, installs more convenient.
Certainly, valve rocker adopts casting to form, and base and support also are integral structure, makes the not fragile of this mechanism like this, longer service life, and manufacturing is also more convenient simultaneously.

Embodiment
As Fig. 1 and Fig. 2 and shown in Figure 3, this structure improved Valve Rocker Organization is arranged on the cylinder head, and it comprises valve rocker 1 and base 2.
As shown in Figure 4, valve rocker 1 is an integral structure, and it forms by casting.Valve rocker 1 is two, and they lay respectively at two gaps of support 3 " mountain " shape.A pin 4 passes the middle part of valve rocker 1 and the pin-and-hole 31 on the support 3, makes the middle part of valve rocker 1 be hinged on the support 3.In the present embodiment, pin 4 is connected on the support 3.Obviously, valve rocker 1 around it with the hinged place swing process of support 3 in its two ends can contact with valve stem with push rod respectively.When push rod moves up and down, this end that valve rocker 1 contacts with push rod is also along with swing, and the other end of valve rocker 1 is equally also being followed swing and this end promotes valve stem in swing process, reaches the purpose that the control valve opens and closes by moving up and down of valve stem.
