Abstract
The utility model relates to Piston for vehicle accessory, particularly a kind of car piston ring two road compression ring.Comprise ring body and coating, it is characterized in that described ring body section is nose shape cone structure, ring body is provided with free open, ring body cylindrical is provided with external conicity; Ring body cylindrical lower end is provided with nose shape groove; Described free open width is 8-10mm; Described external conicity is 1 degree 20 points; Described nose shape groove deep 1.2mm, wide 0.6mm; Described ring body adopts alloy cast iron to make.Compared with the advantage cylindrical structure that to be nose shape cone structure adopt with common ring, be more conducive to the control functional oil strengthening piston ring; Advanced design, rational in infrastructure, process superior, installation using effect is good, and indicators of overall performance reaches domestically leading level.
Description
Technical field
The utility model relates to Piston for vehicle accessory, particularly a kind of car piston ring two road compression ring.
Background technique
In the product of prior art, its piston ring material is all common cast iron, and mechanical strength is obviously good not; That structurally designs is unreasonable simultaneously, also causes and varies qualitatively.
Model utility content
The purpose of this utility model is for above-mentioned defect, provides a kind of car piston ring two road compression ring.
The technical solution of the utility model is car piston ring two road compression ring, comprises ring body and coating, it is characterized in that described ring body section is nose shape cone structure, ring body is provided with free open, ring body cylindrical is provided with external conicity; Ring body cylindrical lower end is provided with nose shape groove.
Described free open width is 8-10mm; Described external conicity is 1 degree 20 points; Described nose shape groove deep 1.2mm, wide 0.6mm; Described ring body adopts alloy cast iron to make.
The utility model has the advantages that compared with the cylindrical structure that nose shape cone structure and common ring adopt, be more conducive to the control functional oil strengthening piston ring; Advanced design, rational in infrastructure, process superior, installation using effect is good, and indicators of overall performance reaches domestically leading level.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional drawing of Fig. 1.
In figure: 1-free open, 2-external conicity, 3-nose shape groove, 4-ring body.
Embodiment
Below embodiment is further illustrated by reference to the accompanying drawings.
With reference to Fig. 1, Fig. 2, solid piston ring 4 is sheet annulus, and have opening, the width at free open 1 place is 8-10mm; As shown in Figure 2, external conicity 2 is 1 degree 20 points, nose shape groove 3, its groove depth 1.2mm, wide 0.6mm.
Innovative point of the present utility model is ring body 4 section is nose shape cone structure, ring body 4 is provided with free open 1, and ring body 4 cylindrical is provided with external conicity 2; Ring body 4 cylindrical lower end is provided with nose shape groove 3; Ring body 4 adopts alloy cast iron to make.On the make adopt oval heat setting process, sealability improves greatly, and light leak rate up-to-standard rate brings up to more than 97% from 60%.
Shown in above Fig. 1 is embodiment in a preferred way; demonstrate substantive distinguishing features and the remarkable progress of this product, the needs that can use according to reality, under the enlightenment of this technology; it is carried out to the equivalent modifications of the aspect such as shape, structure, but all within the protection domain of the technical program.
