Rolling wheel body assembly of fuel feeding pump

The utility model provides a rolling wheel assembly body of a fuel feeding pump, which aims at resolving the problems that in the prior art, rolling wheel inner circles and rolling wheel pin outer circles of rolling wheel body assemblies of fuel feeding pumps of motor vehicle engines are easily abraded, and once the abrasion is severe, damage or failure and the like of the rolling wheel assemblies are caused. The rolling wheel assembly of the fuel feeding pump comprises a rolling wheel body, a rolling wheel pin, a rolling wheel and a positioning block, wherein the thickness of the wall of the rolling wheel is reduced, and a rolling pin is arranged between the rolling wheel and the rolling wheel pin. The rolling wheel body assembly of the fuel feeding pump has the advantages of avoiding sliding friction between the rolling wheel and the rolling wheel pin, preventing the rolling wheel and the rolling wheel pin from being abraded and modifying an ordinary rolling wheel structure into a rolling pin bearing structure, thereby being capable of bearing larger load and higher rotating speed and improving working reliability of the fuel feeding pump under large load and high rotating speed.
