    摘要: The present invention relates to an adjustable camshaft in which an inside shaft and an outside shaft, each being fixedly connected to cams, are mounted so they are rotatable in relation to one another. To produce the relative movement, a hydraulic adjusting mechanism is provided on one of the ends thereof; in the adjusting mechanism, first and second rotatable adjusting elements are each fixedly connected to one of the two shafts opposite one another. Adjacent to the adjusting mechanism, the outside shaft is fixedly connected to a first bearing ring supporting at least the outside shaft in a stationary first abutment. Alternatively, it is essential to the present invention either that the first adjusting element is supplied with hydraulic medium via hydraulic channels running in a second abutment and a second bearing ring or a pressure bearing disk is provided with corresponding hydraulic channels between the adjusting mechanism and the first abutment, the hydraulic channels supplying hydraulic medium to the second adjusting element.

    摘要: The present invention relates to a camshaft (1) having cams (3 and 4) rotatable with respect to one another about the camshaft axis (2) over limited circumferential angles, whereby an inside shaft (5) and an outside shaft (6) are arranged coaxially one inside the other. The cams (3 and 4) that are rotatable with respect to one another each consist of first cams (3) and second cams (4), whereby the first cams (3) are fixedly connected to the inside shaft (5) and the second cams (4) are fixedly connected to the outside shaft (6), each by means of a fixation device (8). It is essential to this invention that the first cams (3) each have a first through-bore (11) which is aligned with a respective second through-bore (12) in the inside shaft (5) when the first cam (3) is installed. In addition, the fixation device (8) is formed by two essentially identical fixation pins (10 and 10′) with respect to their axial longitudinal extent. The present invention also relates to a method for manufacturing such a camshaft (1).

    摘要: The aim of the invention is to provide a reliable and inexpensive camshaft wherein the inner shaft and the outer shaft can be adjusted in a low-friction manner. For this purpose, a camshaft with cams that can be rotated in relation to each other, wherein at least one first cam (3) is rotatably received on the outer shaft (1), is permanently connected to the inner shaft (2) via at least one radial opening in the outer shaft (1). Means (10) for connecting a camshaft rotational drive are provided at the axial ends of the camshaft. The camshaft is also provided with a rotational drive (9) exerting radial supporting forces onto the camshaft.
