Abstract
The utility model relates to a ring-joint type piston; the ring body is formed by the combination of a plurality of cambered steel ring along the circumference; the neighbouring cambered steel rings are in sliding match, and the contact faces are all inclined faces; the whole ring body is embedded in a piston ring groove. As for the cambered steel rings of the utility model, that the contact faces between the cambered steel rings are inclined faces increases the wear resistance ability of the metal. Simultaneous, the clearances which is produced when then steel rings are headed to expand is replenished; the adoption of the positioning pin and the spring increases the elasticity coefficient of the ring body. With the utility model which has a good sealing effect, the life time of the steel body is prolonged to 3-8 times the life time of the common piston; with the advantages of economy and oil saving, the engine doesn't burn to produce the blue fume, and the power is not reduced.
Description
Affiliated field: the utility model relates to a kind of cyclization formula piston.
Background technique: the piston ring in the existing piston utilizes the elastic force of metal to reach the sealing of cylinder body and firing chamber, and its elasticity coefficient space is little, and metallic material is required height, the piston ring frangibility, and its life-span is short, can not run up for a long time, causes engine overhaul.
Summary of the invention: the purpose of this utility model provides the cyclization formula piston of a kind of long service life, good sealing effect.The purpose of this utility model realizes by following structure: the utility model is a kind of cyclization formula piston, ring body is constituted along circumference by a plurality of arc steel loops, for being slidingly matched and surface of contact is the inclined-plane, ring body integral body is embedded in the piston ring groove between the adjacent arc steel loop.Arc steel loop of the present utility model utilizes that surface of contact is the inclined-plane between the arc steel loop, has increased the wear-resisting amount of metal, and the gap that the steel loop expanded by heating is produced replenishes simultaneously, adopts locating stud to adopt spring to strengthen the spring ratio of ring body.The utility model good sealing effect prolongs the steel body life time, improves life-span 3-8 doubly than pot type piston, and motor is the enameling cigarette not, and power does not subtract, and is economical fuel-efficient.
