Publication number: 20120306173Abstract: An apparatus for adjusting the camber and/or toe of a motor vehicle wheel includes a wheel carrier, on which the wheel is rotatably mounted. The wheel carrier is divided into a carrier member receiving the wheel via a wheel bearing, an axle-side guide member, and a bearing assembly arranged therebetween. The bearing assembly includes rotary parts which can be rotated relative to each other and relative to both the carrier member and the guide member and which interact with confronting inclined faces. The wheel bearing includes a radially outer bearing housing, which is clamped by the bearing assembly formed from the rotary parts into a plug-and-socket connection with the carrier member.Type: ApplicationFiled: December 9, 2010Publication date: December 6, 2012Applicant: Audi AGInventors: Karl-Heinz Meitinger, Wilfried Michel, Christoph Kossira, Hugo Müller, Wolfgang Schmid
