Abstract
The invention provides an engine valve rocker. According to the scheme, the engine valve rocker comprises a rocker body and a needle bearing, wherein the needle bearing is arranged on the rocker body in a pivot mode and makes contact with a cam, and one end, close to an engine valve rod, of the rocker body is provided with a through hole; a locating pin is fixedly inserted into the through hole; a valve contact device which can rotate is arranged on the locating pin in a pivot mode; the lower end of the valve contact device makes contact with the engine valve rod. By means of the scheme, friction loss between the rocker and a valve can be reduced, side force borne by the valve is lowered, and response speed of the valve is increased.
Description
Technical field
What the present invention relates to is a kind of engine valve controlling device, especially a kind of engine valve rocker arm.
Background technique
In the prior art, known technology is, develop rapidly along with automotive industry, people propose more and more higher requirement to the power character of motor car engine, Economy, impel motor car engine to strengthening, at a high speed, low oil consumption, low emission future development, thereby also component product has been proposed to requirements at the higher level.Valve rocker is as one of motor car engine vital part, and improving its wear resistance, reducing friction factor, lightweight, long-life etc. is valve rocker design and the target of manufacturing pursuit.
In the external interior valve rocker of producing, there is roller rocker arms and be not with two kinds of roller rocker arms at present.Wherein extensive with roller rocker arms use, in this, rocking arm is comprised of two-part, and main body is rocker body, and another part is needle bearing; After the bearing pin of needle bearing and rocker body riveted joint, becoming one is the typical structure of this rocking arm.
Needle bearing contacts with cam, during work, with cam, rotate and power is passed to valve by rocking arm and reduce friction factor with this, improve working life, but this rocking arm and valve contact position are fixed structure, friction mode is sliding friction, frictional loss is larger, is also the key factor that causes that rocking arm and associated part lost efficacy., this is the existing deficiency of prior art.
Summary of the invention
Object of the present invention, is exactly for the existing deficiency of prior art, and a kind of technological scheme of engine valve rocker arm is provided, and this scheme can reduce the frictional loss between rocking arm and valve, has reduced the suffered lateral force of valve, has improved valve speed of response.
This programme is achieved by the following technical measures: a kind of engine valve rocker arm, and the needle bearing contacting with cam on including rocker body and being riveted on rocker body, the one end near engine air valve rod in rocker body has through hole; In through hole, be fixedly inserted with locating stud; On locating stud, riveted joint has rotating valve contact device; The lower end of valve contact device contacts with engine air valve rod.
As this programme preferably: valve contacting point device is bearing.
As this programme preferably: valve contact device is the slip ring being riveted on locating stud.
As this programme preferably: valve contact device is the slip ring that is riveted on the upper end open on locating stud.
As this programme preferably: valve contact device is to be enclosed within the boss that the lower end on locating stud is cambered surface.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due to the valve contact device connecting part in valve stem and rocker body in this scheme, valve contact device can rotate on locating stud, so the direct friction mode of valve contact device and valve stem is rolling friction, the frictional loss of rolling friction is significantly less than the frictional loss of sliding friction, can significantly reduce frictional loss and also reduce the suffered lateral force of valve stem, improved speed of response and the sensitivity of valve simultaneously.
As can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and progressive significantly, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that valve contact device is the structural representation of the rocking arm of slip ring.
Fig. 3 is that valve contact device is the structural representation of rocking arm of the slip ring of upper end open.
Fig. 4 is that valve contact device is the structural representation of the rocking arm of boss.
In figure, 1 is cam, and 2 is needle bearing, and 3 is rocker body, and 4 is locating stud, and 5 is bearing, and 6 is valve stem, and 7 is slip ring, and 8 is boss.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, a kind of engine valve rocker arm of this programme, the needle bearing contacting with cam on including rocker body and being riveted on rocker body, the one end near engine air valve rod in rocker body has through hole; In through hole, be fixedly inserted with locating stud; On locating stud, riveted joint has rotating valve contact device; The lower end of valve contact device contacts with engine air valve rod; Valve contacting point device is bearing; Valve contact device is the slip ring being riveted on locating stud; Valve contact device is the slip ring that is riveted on the upper end open on locating stud; Valve contact device is to be enclosed within the boss that the lower end on locating stud is cambered surface.
In work engineering, because valve contact device can rotate on locating stud, therefore the friction mode between valve contact device and valve stem is rolling friction, the frictional loss of rolling friction is significantly less than the frictional loss of sliding friction, can significantly reduce frictional loss and also reduce the suffered lateral force of valve stem, improved speed of response and the sensitivity of valve simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
