Wheel for a motor vehicle and method of making same

摘要

A rim for a motor vehicle has several radial hollow spokes in a wheel disk which is manufactured in a die tool and is connected with a rim well. The cast wheel disk is connected with a deformed rim well by friction welding in the area of a rim flange. On an interior side, the wheel disk has at least one flat welding surface which extends around as an annulus and which is arranged so that it corresponds with another opposite flat welding surface of the rim well. In at least one of the hollow spokes, one reinforcing rib is arranged which extends radially from the wheel center axis toward the outside and connects two opposite walls of the spoke with one another.
