Description
Technical field
The utility model is related to piston field more particularly to a kind of Split pistons installing oil storage box additional.
Background technology
Piston of automobile cans be compared to the central position of automobile engine, for bearing gas pressure, and is driven and is connected by piston pin
Bar drives bent axle to rotate, and the component part of top land or combustion chamber accounts for extremely important when engine operates
Status.
In recent years, due to the continuous improvement of engine reinforcing degree, rotating speed, mean effective pressure and the piston of engine are flat
Equal speed all has increased significantly than before, therefore the thermic load of engine and mechanical load both increase, but piston
Cooling there is no reinforcing, temperature rise under high intensity operating mode, it is easier to fatigue deformation, and lubricating oil is difficult to rest on piston
It is middle timely to be cooled down, it needs to improve.
Utility model content
The purpose of this utility model is to provide a kind of Split pistons installing oil storage box additional, are lubricated the temporary of oil, carry
Rise piston cooling effect.
For this purpose, the utility model uses following technical scheme：
A kind of Split piston installing oil storage box additional, including：Oil storage box, piston barrel and piston lid, the piston lid
Be arranged at the top of piston barrel, the oil storage box is arranged in the lower section of piston lid, the oil storage box include box top plate and
Sleeve, the box top plate are arranged at the top of sleeve, and piston lid lower surface is provided through the screwed pipe of box top plate, described
Hub internal bore bottom is provided with the conical flow guiding cover pointed up, and conical flow guiding cover bottom is provided with oil leaking hole.
Wherein, the screwed pipe, piston barrel and piston lid are integrated aluminium alloy structure.
Wherein, the fastening nut positioned at box top plate bottom is provided on the screwed pipe.
Wherein, the bottom symmetrical of the piston barrel is provided with pin shaft fixing seat.
Wherein, it is horizontally arranged with bearing pin mounting hole on the pin shaft fixing seat, spring is provided in the bearing pin mounting hole
Card fixing groove.
Wherein, compression and oil ring groove are provided in the piston barrel outer circle.
Wherein, oil storage vessel is formed between the conical flow guiding cover outer wall and sleeve lining.
The beneficial effects of the utility model：A kind of Split piston installing oil storage box additional, during piston motion, lubricating oil is not
Disconnected disengaging piston barrel, utilizes conical flow guiding cover so that lubricating oil enters oil storage vessel and keeps in, and strengthens the cold of piston lid
But it, and by oil leaking hole is sustained, facilitates the replacement of lubricating oil, good cooling results, use more to stablize, avoid piston cap
The problem on deformation of body.

It is horizontally arranged with bearing pin mounting hole 11, the installation of axis pin is facilitated, Spring Card fixing groove is provided in the bearing pin mounting hole 11
12, the installation of Spring Card is facilitated, the limit at axis pin both ends is carried out using Spring Card.
In the present embodiment, compression 7 and oil ring groove 13 are provided in 2 outer circle of the piston barrel, respectively carry out compression ring and
The safety of oil ring, air-tightness are good.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
