Light gauge wheel

The utility model relates to a light gauge wheel, weld two synthetic spare parts including adopting carbon dioxide gas protection welder to plant, two radials that spare part is adopting rim that roll forming processing technology makes, that adoption resistance welder plants weld forming and adoption spinning shaping processing technology to make respectively, be equipped with a plurality of ventilation hole and a plurality of bolt hole of equipartition on the reducing circumferencial direction on the radials respectively, the cross section of radials is U type structure, the cross section at rim both ends is the stepped ramp type structure, the stepped ramp type structure includes the step of both sides even as an organic whole and is located the plane that the middle part is used for connecting the radials. The utility model relates to a light gauge wheel, whole light in weight to the heat dissipation is good, has reduced the biasing distance, has improved the bearing strength, adopts the centre bore locat
