Be provided with keyway on described seat ring and the outer ring, seat ring is connected by the post key with the outer ring.
Described resetting means is a Returnning spring, and this Returnning spring is arranged in the caulking groove of a rib.
Described voussoir roller bearing and deep groove ball bearing are set to the shared retainer of one, and retainer one side is provided with upper cover plate, and opposite side is provided with lower cover slip.
Described seat ring is provided with several pins, and it is on the circumference in the center of circle that pin is arranged on the inner ring center.
Described upper cover plate is provided with projection and the inserting pin that matches with caulking groove.
Split is provided with packing ring on the described pin.
Above scheme is adopted in invention, electric vehicle overrunning clutch, this clutch term electric motor car, it has seat ring and outer ring, seat ring and outer ring are wholely set, such setting prevents that outer ring and seat ring from use forming wearing and tearing and cooperating not tight, be provided with inner ring in the outer ring, be provided with unidirectional limit stoper between outer ring and the inner ring, unidirectional limit stoper is a roller bearing, and roller is the voussoir roller, and be provided with deep groove ball bearing between outer ring and the inner ring, the setting of this deep groove ball bearing has reduced the generation of noise, and inner surface and inner ring outer surface one side circumferentially are provided with the cambered surface groove, and this groove is settled for the steel ball of deep groove ball bearing, prevented beating of axial-radial, make that the structure of clutch is more stable, increase working life, and useful benefit of the present invention is that moment of torsion is big, noise is low, radial displacement is little, and axial runout is little, has prolonged working life.
