Self lubricated bowden cable - has hose, with longitudinal ribs on inner and outer surface with grease pockets between

摘要

The Bowden cable consists of a traction wire inside a synthetic hose, which in turn is surrounded by a jacket formed by a wire spiral. The hose (2) has ribs (4,5) extending in longitudinal direction, on its internal and external surfaces. All sections have overlapping tolerances and the tolerances of the internal dias. of the hose and jacket (3) are +0/-0.1mm, and those of the external dia. of traction wire (1) and hose, are +0/0,05 mm. The ribs extend parallel to the arms in a straight line, or in a helical shape. Chambers (6) formed between the ribs are filled with grease.
