Abstract
The invention discloses a single-groove double-piece twisted combined piston ring arranged on an air ring groove on an engine piston. The piston ring mainly comprises an upper ring (1) and a lower ring (2), and the contact surface between the upper ring and the lower ring is a smooth plane. In the process of assembling an engine, an upper ring opening (3) and a lower ring opening (4) of the single-groove double-piece distortion combined piston ring are staggered by 180 degrees and then are installed in a piston ring groove, and then a piston with the piston ring is installed in a cylinder sleeve by using a special installation tool for the piston ring, so that the function of sealing air is realized. The piston ring can effectively reduce fuel oil consumption and engine oil consumption of the engine, and can improve the dynamic performance, reliability and the like of the engine. The technology is applied to a military high-power engine, so that the maneuverability, flexibility and reliability of military vehicles and the battlefield fighting capacity and viability are improved.
Description
Technical field
Patent of the present invention belongs to the component that are used to improve aspect performances such as engine power performance, reliability, Economy.
Background technique
Piston ring-cylinder liner is one of topmost friction pair in the motor.The fundamental function of piston ring has determined its structure that opening must be arranged, the existence of opened gap, help the installation and removal of piston ring in the final assembly process on the one hand, guaranteed that on the other hand piston ring itself has certain elastic force, make piston ring in engine operation process, can be close to cylinder-barrel surface, cause the fuel oil consumption to increase in the crankcase thereby effectively stop a large amount of combustion gas to be scurried into, stop a large amount of machine oil to be scurried into simultaneously and cause engine oil consumption to increase in the crankcase from the gap between cylinder and the piston from the gap between cylinder and the piston.Therefore, piston ring is one of very important component in the motor.But the existence of opened gap also has its deficiency, and promptly under the condition of high combustion chamber pressures combustion gas, a part of combustion gas meeting is scurried in the crankcase by piston ring gap, and a part of machine oil also can be scurried in the cylinder by opened gap simultaneously.At above actual conditions,, developed single-groove double-piece distortion combination type piston ring for effectively solving the existing deficiency of opening piston ring itself.
Summary of the invention
Patent of the present invention be the exploitation a kind of single-groove double-piece distortion combination type piston ring, it is characterized in that: in the motor assembly process, with single-groove double-piece distortion combination type piston ring go up ring (1) and down (2) two on ring encircle openings and interlace after 180 °, burnishing surface is close together is installed in the piston ring groove, to have in the installing piston into cylinder of this piston ring with the piston ring special tool at last, realize the envelope airway dysfunction.
The beneficial effect of patent of the present invention is that novel piston ring is suitable for installing and using on various vehicular engines, its application can improve engine performance, prolong cylinder sleeve and piston life, power character, reliability and the Economy of improving motor had very big potentiality, and its predominant use is: (1) effectively reduces the fuel oil consumption; (2) effectively reduce engine oil consumption, prolong the life time of machine oil; (3) improve engine power performance; (4) functional reliability of raising motor.

Embodiment
Patent of the present invention provides a kind of single-groove double-piece distortion combination type piston ring.In single-groove double-piece distortion combination type piston ring schematic representation shown in Figure 1, the smooth flat that will go up ring (1) and following ring (2) fits tightly, utilize the piston ring setting tool to be installed in the piston ring groove, utilize the piston ring special installation tool will be equipped with two then and be superimposed and the interlace piston of 180 ° of piston rings of opening is encased in the cylinder sleeve of engine, thereby realize seal action combustion gas.
Claims (3)
1, a kind of single-groove double-piece distortion combination type piston ring that is installed in compression on the engine piston is characterized in that: comprise that is gone up ring (1) and one ring (2) down, last ring and encircle the edge down and encircle an opening (3) and opening (4) are respectively arranged in week.
2, according to the described single-groove double-piece distortion combination type piston ring of claim 1, it is characterized in that: the surface of contact of two ring stacks is planes, guarantee that upper and lower two loop contacts faces have degree of applying preferably.
3, according to the described single-groove double-piece distortion combination type piston ring of claim 2, it is characterized in that: upper and lower two rings are when assembling, and its opening will interlace 180 °.
