HOLLOW DRIVE SHAFT WITH INTEGRATED VIBRATION ABSORBER

摘要

The invention relates to a drive shaft with an integrated vibration absorber. The aim of the invention is to reduce effectively, in a targeted manner and by simple means, excessive vibration in a drive shaft embodied as a hollow shaft (8) by acting on the vibration maximum (antinode). A vibration absorber (2) positioned inside the hollow shaft (8) consists of a damping mass (absorber mass) (4) and an elastic coupling element (6). The absorber mass (4), which is actively connected to the inner wall of the hollow shaft (8) via the elastic coupling (6), is rotationally and axially symmetrical and at its centre has a necking (12) for receiving the elastic coupling element (6). The invention also relates to the use of said drive shaft as a drive shaft (8) (hollow shaft) mounted transversally in the vehicle and as a drive shaft (8) mounted longitudinally in the vehicle (cardan shaft embodied as hollow shaft).
