Abstract
The utility model discloses an expansive piston ring for an internal combustion engine, which is mainly composed of a ring body with an interface. The utility model has the characteristics that the interface is designed into inclined overlap, sealing state of the interface of the ring body can be effectively maintained, the utility model can be still used normally when cylinder wear is increased within 700 decimillimeters, and thus service life of a piston ring is effectively enhanced.
Description
The utility model relates to a kind of piston ring for combustion engines, particularly a kind of taking of piston ring joint formula piston ring that rises that improved.
Now the used piston ring of internal-combustion engine is because to-and-fro motion in cylinder for a long time, use a period of time after because normal wear, working clearance increase phenomenon will appear at jointing, cause cylinder to lose heart or gas leakage, thereby influence the power performance of internal-combustion engine, form scrapping of ring.For improving the working life of piston ring, now interface also having occurred is the piston ring of overlap joint type, just forms at jointing to overlap, and has effectively improved the working life of piston ring.But this mode still can not be stopped fleeing of air-flow and machine oil fully, can form straight-throughly equally, causes losing heart and gas leakage of piston ring.
The purpose of this utility model is to provide a kind of long service life, high the taking of the sealability formula piston ring that rises.
The utility model is achieved in that
A kind of formula piston ring that rises of taking mainly is made up of the ring body of band interface, and this interface is an overlap joint type, it is characterized in that: described interface is the inclined overlap joint.
For increasing practicability, the cross section of above-mentioned interface end is trapezoidal.
After the utility model adopts above structure, because with the Interface design of piston ring is the inclined overlap joint, can effectively safeguard the sealing state of ring body jointing, improve the sealability of piston ring, can reach automatic expanding especially and increase function, cylinder wear still can normally use in increasing 700 decimillimeters, thus the working life of effectively having improved piston ring.No interface gaps, do not have mutual counterpart, stopped fleeing of air-flow and machine oil, it is big to have the cylinder compressive force, and fuel oil, lubrication oil consumption are low, the effect that toxic emission is few.Can effectively save fuel oil 15%, increase power 10% and reduce toxic emission more than 40%.
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that ring body, 2 is interface.
As shown in Figure 1, 2, the utility model is that a kind of internal-combustion engine is with taking the formula piston ring that rises, mainly form by the ring body 1 of band interface 2, interface 2 is an overlap joint type, wherein an end rides on the other end, fits like a glove, the cross section of above-mentioned interface 2 ends is designed to trapezoid, makes interface 2 form the inclined overlap joint.So just can effectively safeguard the sealing state at ring body 1 interface 2 places, improve the sealability and the working life of piston ring.
The cross section of these interface 2 ends can be designed to also that other is trapezoidal.
Claims (2)
1. take the formula piston ring that rises for one kind, mainly be made up of the ring body (1) of band interface (2), this interface (2) is an overlap joint type, it is characterized in that: described interface (2) is the inclined overlap joint.
2. the formula piston ring that rises of taking according to claim 1 is characterized in that: the cross section of described interface (2) end is trapezoidal.
