Abstract
The utility model discloses a ball ink casting piston ring, including the ring body, the ring body upper end is broken and is formed the fracture, and the left and right-hand member end wall of fracture has the caulking groove, still includes metal elastomer, and in metal elastomer located the fracture, metal elastomer left and right-hand member connected an organic whole respectively has the connector, and during the connector imbed the caulking groove respectively, is connected with the heliciform elastomer between connector tip and the caulking groove inner. The utility model discloses simple structure, processing and convenient assembling can improve the structural stability of ring body.
Description
Technical Field
The utility model relates to a piston ring field specifically is a nodular casting piston ring.
Background
Nodular cast piston rings are commonly used in automotive engines to seal. The nodular cast piston ring of traditional structure has the ring body of a fracture for the centre, establishes the heliciform elastomer in the fracture often, and the nodular cast piston ring of this structure has yielding problem.
The utility model aims at providing a nodular casting piston ring to solve the yielding problem of prior art nodular casting piston ring.
In order to achieve the above purpose, the utility model discloses the technical scheme who adopts is:
Nodular cast piston ring, its characterized in that: the metal elastic body is arranged in the fracture, the left end wall and the right end wall of the fracture are respectively connected with a connecting body, the connecting bodies are respectively embedded into the caulking grooves, one end distance is arranged between the end part of each connecting body and the inner end of each caulking groove, and a spiral elastic body is connected between the end part of each connecting body and the inner end of each caulking groove.
The nodular cast piston ring is characterized in that: the thickness of the connecting body is consistent with that of the caulking groove.
The nodular cast piston ring is characterized in that: the shape of the connector is matched with that of the caulking groove, but the arc length is smaller than that of the caulking groove.
The nodular cast piston ring is characterized in that: the connecting body, the spiral elastic body and the metal elastic body are connected into a whole.
The utility model discloses simple structure, processing and convenient assembling can improve the structural stability of ring body, reduce the influence that the piston ring warp.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the structure assembly schematic diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the nodular cast piston ring comprises a ring body 1, a fracture 2 is formed by breaking the upper end of the ring body 1, caulking grooves 3 are respectively arranged on the front side faces of the end walls of the left end and the right end of the fracture 2, the nodular cast piston ring further comprises a metal elastic body 4 with the elastic modulus smaller than that of the ring body 1, the shape of the metal elastic body 4 is consistent with that of the fracture 2, the metal elastic body 4 is arranged in the fracture 2, the left end and the right end of the metal elastic body 4 are respectively connected into a whole to form a connecting body 5, the connecting body 5 is respectively embedded into the caulking grooves 3, one end distance is arranged between the end of the connecting body 5.
The thickness of the connecting body 5 is consistent with that of the caulking groove 3. The shape of the connecting body 5 is matched with that of the caulking groove 3, but the arc length is smaller than that of the caulking groove 3. The connecting body 5, the spiral elastic body 6 and the metal elastic body 4 are integrally connected.
Claims (4)
