A four-point contact bearing for steering mechanism of motor car, has rolling elements comprising point-like pads with inner and outer rings, where pads are arranged on connecting line to form angle with radially extending symmetry axis

摘要

The bearing (13) has multiple rolling elements (20) i.e. balls, serially arranged one behind another, where the rolling elements comprise point-like pads with an inner ring (22) and an outer ring (21). The point-like pads are arranged on a connecting line to form an angle of 0-90 degrees with a radially extending symmetry axis of the bearing. The rolling elements comprise a bias, and outer diameter of the inner ring is smaller than the internal diameter of the outer ring. The point-like pads with the inner ring are arranged opposite to the point-like pad with the outer ring.
