Abstract: The present disclosure provides a compound wheel assembling apparatus including a tensioning and fixing component and a locating ring; the tensioning and fixing component is arranged to extend into a center hole of a flange to tension and fix a flange; the tensioning and fixing component includes a base plate, a flange plate, springs, expanding petals and an expanding core; the locating ring is arranged around the base plate, and has a center axis overlapping a center axis of the base plate; the locating ring has a circle of circular-ring-shaped protrusion on its outer side.

Abstract: A lightweight wheel is provided, which includes a flange, a plurality of titanium alloy spokes and a carbon fiber rim, herein the flange is positioned at a middle part of the carbon fiber rim, the plurality of titanium alloy spokes are connected between the flange and the carbon fiber rim, and the plurality of titanium alloy spokes are uniformly distributed in pairs along the circumference; and one end of each of the titanium alloy spokes combined in pairs is fixed on the flange in a centralized mode, and another end is fixed separately at the carbon fiber rim, making the titanium alloy spokes combined in pairs a fan shape. An automobile is also provided.
