| 摘要 |
<p>The invention concerns a remote control cable (C) comprising in particular an axially mobile central strip guided in the sheath (5) by roller elements and sliding between a first rail and a second rail diametrically opposite and an output rod (A) connected to each of said plate ends and sliding inside a sheath terminal (B). The invention is characterised in that said sheath terminal (B) comprises between its inner surface and said output rod (A) outer surface, means axially guiding (20) said rod (A) and means (10) for reducing the radial frictions between said rod (A) and said terminal (B); said means (20) axially guiding said output rod (A) comprises at least one ring (20) with sufficient length to ensure said rod axial guiding relative to said terminal (B). Said ring (20) consists of two cylindrical coaxial respectively inner (30) and outer (40) elements defining between them cages (14) wherein are enclosed trains of balls (10), said cages (14) comprising at least one cavity (15) emerging at least partly on the said inner cylindrical element (30) inner surface (32) so as to enable said balls (10) rotary contact with said rod (A). Said means friction reducing means comprise balls (10) arranged between said terminal (B) inner wall and said rod (A) outer surface so that they can come into rotating contact with said rod (A) outer surface.</p> |
