Patent ID: 7610890

Claim:
A camshaft having contrarotating cams for motor vehicles, comprising: a) an inside shaft and an outside shaft, the shafts being arranged so that they are contrarotating one inside the other, b) a first cam rotatably mounted on the outside shaft and fixedly connected to the inside shaft through at least one radial opening in the outside shaft; c) a second cam fixedly connected to the outside shaft; d) connecting means for connecting a camshaft rotary drive provided on one axial end of the camshaft, wherein the connecting means allow a contrarotation of the first and second cams that is limited in a circumferential direction; e) a rotary drive exerting radial supporting forces acting on the camshaft; and (f) a connection between the connecting means and the outside shaft for transferring transverse supporting forces acting radially on the camshaft exclusively to the outside shaft from the camshaft rotary drive; wherein the connecting means comprises a connecting pin as a first force transfer element between the rotary drive and the inside shaft or the outside shaft, said connecting pin passing through a recess provided in one of the shafts and being secured in the other respective shaft, wherein the recess allows a rotation of the connecting pin that is limited in a circumferential direction of the camshaft and holds the shaft through which the connecting pin passes, while the connecting pin is supported in an axial direction of the camshaft with a lowest possible play in the recess.
