CAMSHAFT WITH SLIDING CAM PACKET

摘要

The invention relates to a camshaft (1) for the valve drive of an internal combustion engine, comprising a base shaft (10) and at least one sliding cam packet (11) comprising multiple profiled cams (12). The base shaft (10) extends through a passage (13) in the sliding cam packet (11) such that the packet is received on the base shaft (10) in an axially movable manner. Means (14) for forming a torque-transmitting connection between the base shaft (10) and the sliding cam packet (11) are provided. According to the invention, the means (14) comprise elongated needle bearing elements (15), a first part of the circular cross-section of said elements sitting in a longitudinal groove (16) in the passage (13) of the sliding cam packet (11) and a second part of the same cross-section sitting in a longitudinal groove (17) on the outside of the base shaft (10).
