Description
Technical field
The invention belongs to engine component, be specifically related to a kind of framework rocking arm.
Background technique
At present, high-power diesel engine Four-valve cylinder head is in the situation that adopting air flue in parallel both at home and abroad, arrange that in four valves, the main actuator rocking arm of distribution device all adopts forked type rocking arm, drive two valve openings of the same name and close by two forked type bars in forked type rocking arm.The structural type of this rocking arm is generally both arms fork shaped lever, has the features such as structure is comparatively simple.But this rocking arm can only be used for cylinder cap uses air flue in parallel, the layout of the air flue that can not be used for connecting can be subject to the restriction of air flue form in distribution device is arranged; And this rocking arm because of both arms forked type be elongate rod, cross section is generally T-shaped structure, size itself is arranged comparatively difficulty of oil leab, the large not and both arms forked type bar of this rocking arm rigidity is difficult to the rigidity requirements such as guarantee, in the time driving two valves of the same name, there is large phase deviation in the opening and closing of valve often, the error of port timing is larger, can affect the performance of motor.
Summary of the invention
The present invention can only use air flue in parallel in order to solve existing forked type rocking arm exactly, and causes in distribution device layout being subject to the defect of the restriction of air flue form, and a kind of framework rocking arm is provided.
The technical solution used in the present invention: a kind of framework rocking arm, comprise hollow stud 1, rocker arm bush 2, pitman arm shaft 3, rocker body 4, bearing 5, ball stud 6, universal ball end is adjusted bolt 7, bolt 8, wherein rocker body 4 is by obliquity rod 9 and wishbone 10 global formations, pitman arm shaft 3 middle parts are cylinder, two ends are flat cylinder, its one end is through with the first oil circuit that leads to pitman arm shaft 3 middle parts, pitman arm shaft 3 sides are provided with the second oil circuit being communicated with the first oil circuit, inside turns has the hollow stud of the first oil duct 1 to be connected with pitman arm shaft 3 one end, wherein said the first oil duct is communicated with the first oil circuit, bolt 8 is connected with the other end of pitman arm shaft 3, and hollow stud 1 is all connected with engine body by bearing 5 with bolt 8, rocker body 4 is sleeved on pitman arm shaft 3, and be equiped with rocker arm bush 2 between rocker body 4 and pitman arm shaft 3, rocker body 4 inside are provided with the 3rd oil duct, the ball stud 6 that is provided with the second oil duct is connected with the obliquity rod 9 in rocker body 4, described the second oil duct is communicated with the 3rd oil duct, the universal ball end adjustment bolt 7 that is provided with the 4th oil duct is connected with the valve end that intersects of rocker body 4, described the 4th oil duct is communicated with the 3rd oil duct, and described the second oil circuit is communicated with the 3rd oil duct.
The two ends of the wishbone 10 of described rocker body 4 intersects a place, forms square shape structure.
Further, rocker body 4 adopts medium carbon alloy steel to forge.
The present invention compared with prior art its beneficial effect is: oil leab arrangement convenience of the present invention, can on any one arm of both sides, can arrange oil duct, and can easily realize the lubricated of valve end and push rod end; The present invention all can realize the demand of four valves layout distribution devices on air flue in parallel and series connection air flue; Framework rocking arm rigidity of the present invention is larger, can ensure valve opening of the same name and close synchronously, and have port timing accurately, distribution device has good power performance, can be applicable on the high power engines such as engineering machinery, car and boat power, gas engine; The framework rocking arm of current this structure successfully totally turns round 2000 hours on certain high-power gas motor.
