Publication number: 20050067882Abstract: The invention relates to a wheel rim, in particular a spoked wheel rim for motor vehicles consisting of sheet-steel. Said rim is assembled from various parts: an inner screw-on flange (1b), a central rim ring (1a) and an external rim well (3, 4, 5). The rim ring (1a) and the screw-on flange (1b) form an inner bearing shell (1) for the main bearing load of the wheel rim. Said bearing shell (1) is covered by an external design shell (2) consisting of sheet-steel, forming a hollow chamber (7). Said design shell is connected in a fixed manner to the screw-on flange (1b) and the rim flange (3) and is configured to support an auxiliary bearing load.Type: ApplicationFiled: June 5, 2002Publication date: March 31, 2005Inventors: Klaus Bluemel, Jens Stach

Patent number: 6296319Abstract: A fastening arrangement for a motor vehicle wheel made of a light metal alloy which is formed by an interior wheel shell and an exterior wheel shell which are fastened to a wheel disk chamber by way of wheel bolts which are arranged concentrically with respect to a wheel hub. The two shells of the wheel can be connected in a mutually sealed manner by way of wheel bolts inserted in bushes, and the bushes are pressed into bores of the shells and held in an embedded manner in a sealing mass. A spacer member is interposed between the wheel chamber and the interior wheel shell. The spacer member is made of a material different than the material of the interior wheel shell and the material of the brake chamber, to facilitate corrosion resistance.Type: GrantFiled: December 7, 1998Date of Patent: October 2, 2001Assignee: Dr. Ing. h.c.F.
