Description
Technical field
The invention belongs to engines distribution structure member technical field, more particularly, to a kind of engine roller rocking arm.
Background technology
Rocking arm is one of important parts in engine valve actuating mechanism, and its function is the motion and effect for transmitting cam
Power, changes direction and is transmitted to valve, make valve opening.Rocking arm shape matching in valve actuating mechanism is complicated.At present, it is high-power both at home and abroad
The structural shape of diesel engine rocking arm is generally single armed or both arms fork shaped lever, with structure it is relatively simple the features such as.And it is this
Rocking arm is elongate rod because of both arms forked type, and this rocking arm rigidity is not big enough and both arms forked type bar is it is difficult to ensure that rigidity requirement, while
The demand of tight space overhead camshaft arrangement is not adapted to, and valve actuating mechanism frictional work is big;It is past when driving two valves of the same name
There is big phase deviation in opening and closing toward valve, and the error of port timing is larger, can influence the performance of engine.
The content of the invention
In view of this, the present invention is directed to propose a kind of engine roller rocking arm, can be achieved the high compact Layout top of Four valve
Put the demand of camshaft valve actuating mechanism.And roller rocking arm rigidity is larger, it is ensured that valve opening of the same name and closing are synchronous, have
Accurate port timing.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way:
A kind of engine roller rocking arm, including rocker body, universal ball structure and roller bearing, the rocker body are U
Type structure, including interlude and the fork-type arm at its two ends, two fork-type arms are by the transition circle segmental arc and straight line coupled with interlude
Section is constituted;The end of two fork-type arms of the rocker body is respectively provided with one and opens a grade bearing hole, each opens grade bearing hole and installs one
Roller bearing is covered, each roller bearing is made up of roller and roller axle;The two ends of the interlude of the rocker body are respectively provided with
One mounting hole, each mounting hole installs a universal ball structure, and the bottom connection pressure head of the universal ball structure is described universal
Upper surface one end that spherical structure is located at interlude is installed by universal ball end adjustment bolt;Oil leab is provided with inside the rocker body,
The oil duct that lubricating oil is entered back on two fork-type arms after being entered by the oil circuit on rocker arm shaft in rocker body is to lubricate valve rod end
And cam end.
Further, it is stifled provided with rocking arm oil between the opening on the inside of grade bearing hole of the roller and rocker body.
Further, the oil duct in the fork-type arm is provided with steel ball in one end of valve.
Further, the interlude is linear pattern.
Relative to prior art, the present invention has the advantage that:
(1) roller rocking arm of the present invention can realize the demand of the high compact Layout air dispensing machine for top-set camshaft of Four valve.And
And roller rocking arm rigidity is larger, it is ensured that valve opening of the same name and closing are synchronous, there is accurate port timing.
(2) between the bearing outer ring and camshaft of roller rocking arm for roll plus slide, can be effectively reduced rocking arm and
Friction and wear between camshaft, valve actuating mechanism friction power loss reduction, valve actuating mechanism has good power performance.
(3) the oil leab arrangement of roller rocking arm of the present invention is convenient, and oil can be individually arranged on each arm of both sides
Road, can easily realize the lubrication of valve end and each roller bearing;Engine consumption can also be reduced to a certain extent.Rolling
Pillar rocking arm can be applicable on the high reinforcing stimuluses such as engineering machinery, car and boat power, gas engine.
