Symmetry welding piston

Abstract

The invention discloses a symmetry welding piston, and relates to the technical field of engines. The piston comprises a protection top layer, a dampproof layer is arranged on the outer surface of thelower end of the protection layer, a piston head is arranged on the outer surface of the lower end of the dampproof layer, a groove is formed in the outer surface of the lower end of the piston head,and a piston pin base is arranged on the outer surface of the lower end of the groove. Through the symmetry welding piston, during use, the piston is more safer, through matching of the adjustable piston head and the movable piston pin base inside, the service life of the piston is prolonged, meanwhile, when the piston works, the piston is safer and stable, the piston head passes through a telescopic buckle and a fixed clamp on the lower end of a piston ring groove, adjusting and fixing are achieved, the work efficiency of the piston is improved, the heat insulation of the piston is reinforced through the isolation layer in the piston pin base at the lower end, the whole service life of the piston is prolonged, the piston is practical, and the better use prospects are brought.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a symmetrically welded piston. Background technique [0002] The piston is a reciprocating part in the cylinder block of an automobile engine. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat-absorbing area. With the development of the engine, the engine's explosion pressure is getting higher and higher, and the power and torque are getting higher and higher, and the heat load of the piston is getting higher and higher. High, although the aluminum piston has the advantage of light weight, it has gradually been unable to meet the requirements of high power, high reinforcement and low emission of the engine, and the aluminum piston is becoming more...
