Abstract

See full text

An adjustable camshaft can be used in a valve drive of an internal combustion engine. The adjustable camshaft may include an inner shaft rotatably supported by and concentric with an outer shaft. A cam element may be rotatably supported on the outer shaft such that the outer shaft extends through a cam bore of the cam element. The cam element may be rotatably-fixed to the inner shaft, in some cases, by way of a bolt. Further, a bearing sleeve that is rotatably-fixed to the cam element may be inserted within the cam bore such that a slide bearing gap is formed between the bearing sleeve and the outer shaft. Furthermore, in some examples the cam element may be a collared cam that has a cam base body and a cam collar adjacent to one another.
