CAMSHAFT, ESPECIALLY FOR MOTOR VEHICLE ENGINES

摘要

The invention relates to a camshaft, especially for motor vehicle engines, comprising a first shaft and a second shaft forming a hollow outer shaft (1) and an inner shaft (2) arranged coaxially in the outer shaft (1) and mounted in such a way that it can rotate in relation to the outer shaft (1). Said camshaft also comprises first cams (3a) arranged on the outer shaft (1) in a rotationally fixed manner, and second cams (3b) that are arranged on the outer shaft (1) and fixed to the inner shaft (2). According to the invention, the first shaft and the second shaft are supported against each other in the axial direction (x) by means of a formfitting shape (5), the first shaft, seen in the axial direction (x), comprising a first contact surface (6a) on one side of the formfitting shape (5) and a second contact surface (6b) on the other side of the formfitting shape (5), for supporting the second shaft in a rotationally movable manner by means of the formfitting shape (5).
