Abstract
The utility model discloses a lubricating structure of a motorcycle engine. The lubricating structure comprises a cylinder head (1) as well as rocker arms (2), rocker arm shafts (3), rocker arm rollers (4) and a camshaft (10) which are positioned in the cylinder body, wherein a lubricating oil passage (5) is arranged on the cylinder head (1), and a spraying and lubricating mechanism is arranged on the cylinder head (1) and communicated with the lubricating oil passage (5). The lubricating structure of the motorcycle engine has the advantages of ingenious design, simple manufacturing and large lubricating area, sufficiently lubricates all the components in the cylinder end, lessens the problems in the cylinder end, ensures the stability of the performance of the engine, and improves the working efficiency of the engine.
Description
Technical field
The utility model relates to a kind of motorcycle engine, particularly a kind of motorcycle engine lubricating structure.
Background technique
At present, motorcycle oblique installing type overhead cam engine cylinder head lubricating structure is to be provided with like this: be provided with grease channel in camshaft, the oilhole that is communicated with grease channel is set on camshaft.When camshaft rotated, the rotation motion by camshaft made lubricant oil sputter from the camshaft oilhole, to reach the purpose of camshaft lubrication surface and rocking arm lower surface.Though this mode has arrived lubrication, the lubricated area of this lubricating system is little, and is lubricated not comprehensive, increase the wearing and tearing between camshaft surface and the rocker-arm roller, reduced motor working life, simultaneously, lubricated not comprehensive, make the cylinder head temperature raise, reduced engine operation efficient.
The model utility content
The purpose of this utility model just provides big, the lubricated comprehensive motorcycle engine lubricating structure of a kind of lubricated area.
The purpose of this utility model is to realize by such technological scheme, a kind of motorcycle engine lubricating structure, comprise cylinder head and the rocking arm, pitman arm shaft, rocker-arm roller and the camshaft that are positioned at cylinder block, cylinder head is provided with oil leab, cylinder head is provided with spray lubrication mechanism, and described this mechanism is communicated with oil leab.
For lubricated rocking arm riveting pin, valve spring and cotter seat, spray lubrication mechanism comprise vertically be distributed on the cylinder head and with rocking arm and the corresponding nozzle opening A of pitman arm shaft, described nozzle opening A is communicated with oil leab, described nozzle opening A is 3～6.
For the surface of contact of lubricated rocker-arm roller and camshaft, described spray lubrication mechanism also comprise transverse distribution on cylinder head and with the corresponding nozzle opening B of rocker-arm roller, described nozzle opening B is communicated with oil leab, described nozzle opening B is 2.
For lubricated rocking arm and pitman arm shaft, on each rocking arm, be respectively arranged with oilhole A and oilhole B, the opening of described oilhole is corresponding with nozzle opening A, and the opening of described oilhole B is corresponding with camshaft.
Wherein, the angle of the vertical center line of the center line of described oilhole A and pitman arm shaft axis hole is 20 °～35 °; The center line of described oilhole B and pitman arm shaft axis normal.
Further optimize, the angle of the vertical center line of the center line of described oilhole A and pitman arm shaft axis hole is 30 °.
Owing to adopted technique scheme, the utlity model has design ingenious, make simple, the lubricated big advantage of area, simultaneously, it also has following advantage:
1. the mode that adopts splash lubrication and spray lubrication to combine has improved lubricated area;
2. to the lubricated and cooling between camshaft and rocker-arm roller surface of contact, rocking arm and the pitman arm shaft, improved working life;
Sufficient lubrication each assembly in the cylinder head, reduced the temperature in the cylinder head, guaranteed the stable of engine performance, improved engine operation efficient.
