Abstract

The utility model discloses a pentagram joint tray for a driven hub. The pentagram joint tray for the driven hub comprises a flange, a rim bolt hole, a first joint tray and a second joint tray. Both end faces of the flange are respectively connected with the first joint tray and the second joint tray; the center of the flange is provided with the rim bolt hole; the flange is in an equilateral pentagram of which both sides are symmetrical; all corners of the flange are respectively provided with a pressure riveting bolt hole; the first joint tray is evenly provided with eight first threaded holes at equal distances; and the second joint tray is evenly provided with three second threaded holes at equal distances. The pentagram joint tray for the driven hub, disclosed by the utility model, has the beneficial effects that specific strength is high and thermal conductivity is good; weight reduction and good heat dispersion can be realized; the open through hole at the center of the joint tray is used for installing the outer ring of a tapered roller bearing. The pentagram joint tray for the driven hub is especially suitable for mini-sized motor vehicles used under severe road conditions.
