Abstract

The invention relates to a production technique of cylinder head of tumbrel, in particular to a rocker-arm support for the die-casting cylinder head of the engine of a light motorcycle or a moped. According to the technical proposal provided by the invention, cooling fins are arranged on the main body of the cylinder head; the production technique of the invention is characterized in that: the main body of the cylinder head is integrated with the rocker-arm support of the cylinder head in a die casting way; shaft holes for the rocker-arms are arranged on the rocker-arms of cylinder head and are provided with a rocker-arm shaft; two rocker-arms are arranged on the rocker-arm shaft; a valve adjusting bolt and a valve adjusting nut are positioned at the ends corresponding to the inlet valve and the outlet valve on the rocker-arms; and the other ends of the rocker-arms are positioned in the ejector rob chamber; the rocker-arms can sway around the rocker-arm shaft. The rocker-arm support of the die-casting cylinder head of the invention has the advantages of compact structure, high intensity, good reliability and simple process and assembly manipulation.

Description

technical field [0001] The invention relates to the production technology of the cylinder head of the two-wheel vehicle, in particular to a rocker seat of the engine die-casting cylinder head for mopeds and mopeds, which is suitable for wide application in gas distribution of mopeds and mopeds. Background technique [0002] Due to the requirements of environmental protection and human sustainable development, low energy consumption and low pollution have become the development goals of engines. In recent years, the technology of the rocker arm seat of the engine cylinder head has not been applied on the engine cylinder head of mopeds and mopeds. [0003] The rocker arm seat and the cylinder head of the original mature traditional moped and moped engine cylinder head are separated, not a whole, and the rocker arm seat is tightened on the cylinder head by screws, which has complex structure, difficult processing and assembly, and high cost. shortcoming. Contents of the inve...
