BRUSH ARRANGEMENT USED IN A VEHICLE TO LEAD AWAY CURRENTS

Patentradars sammanfattning

TRATON AB's invention addresses the challenge of securely anchoring a spring-loaded grounding brush inside a narrow-diameter rod housing in automotive applications. The key novelty is a plastically deformable fixation body (made of soft metal) that is first inserted loosely into the elongate housing, positioned correctly using a radial inspection/tool-access hole through the housing wall, and then permanently locked by applying a force through that radial hole to plastically deform the fixation body outward into a diametrically opposite void or through-hole in the housing wall. This eliminates the prior-art reliance on friction alone to retain the spring anchor, providing a robust positive form-lock. A companion method claim covers the sequential steps of insertion, positioning verification, and plastic deformation to achieve this assembly.
