Windscreen wiper system for vehicle - uses retaining ring to hold sealing ring in position in bearing housing with guide element formed of spherical indentation

摘要

The sealing ring (15) is held in the bearing housing (11) by means of a retaining ring (14). The imaginary intersection surface of a segment of the retaining ring has a symmetry axis vertical to the central axis of the retaining ring. The guide element may be a spherical indentation (12) which lies on the indentation ball bearing surface of the bearing housing (11). The outer face of the retaining ring forms a ball zone. ADVANTAGE - Creates a sealed bearing composed of few parts, which are simple and cost-effective to produce.
