Device for braking and clutching wheel of motor vehicle, has fixed-bar and fixed-ball magnets, where distance between surface of specific magnets and surface of rotating ball and/or bar magnets is smaller than specific dimension

摘要

The device has diametrically permanent fixed-bar magnets attached to a rotating drum-outer ring (102) and/or to a holding drum-outer ring (202) parallel to each other and parallel to an axis of rotation (40). An air gap (21) is formed between the holding drum-outer ring and an inner boundary of the rotating drum-outer ring, where dimension (22) of the air gap has an amount of 0.4 mm. Distance between a surface of fixed-ball magnets (310) and/or the fixed-bar magnets and a surface of rotating-ball magnets (300) and/or rotating-bar magnets is smaller than another dimension of 2 mm.
