Multiple telescopic steering shaft

摘要

The telescoping parts of the shaft have protective caps (9), and the shaft is housed, at least in areas, in a protective tube (10). The centred protective caps have an end-side conical opening and at least one diameter enlargement, and on their outer circumference have a profiled face (9.1). A bearing ring (11) is fitted on the outer tube (1) of the shaft inside the area permanently covered by the protective tube. At least one drain hole (12) is formed in the bottom of the protective tube. The protective tube and protective caps may be made of synthetic material or metal.
