Bearing type bush for mounting an anti-roll bar for vehicle or mechanical device

A bearing type bush for mounting an anti-roll bar of a vehicle or a mechanical device comprising:

• pressure bodies made of rubber material surrounding the anti-roll bar;
• bearing plates made of plastic material surrounding the pressure bodies;
• an upper bracket made of plastic material covering the bearing plates from above;
• and
• a lower bracket coupled to a lower portion of the upper bracket and surrounding the bearing plates together with the upper bracket,
• wherein the pressure bodies include two semicircular parts that, when joined, form a circle to fully surround the anti-roll bar,
• wherein on the outer surface of each of the pressure bodies, a cross-shaped outer concave part and four square-shaped outer protrusions protruding due to the formation of the outer concave part are formed,
• wherein the bearing plates are composed of two semi-circular parts, the semi-circular parts form a circle when meeting so that the pressure bodies fit snugly inside each of the bearing plates
• wherein each of the bearing plates includes:
• two sliding protrusions formed along the outer peripheral surface thereof;
• three-sided outer friction surfaces formed between the sliding protrusions and on both sides of the sliding protrusions,
• wherein each of the bearing plates includes seal coupling protrusions formed at both ends thereof with a diameter smaller than that of the outer friction surfaces, thus being generally step-shaped due to the sliding protrusions, the outer friction surfaces, and the seal coupling protrusions, and
• wherein the upper bracket includes a semi-circular upper assembly surface formed on the upper inner surface of the upper bracket and surrounds the outer surface of the bearing plates, and the lower bracket includes a semi-circular lower assembly surface formed on the upper inner surface thereof, to be assembled while enclosing the bearing plates coupled with the pressure bodies, and
• wherein sliding concave parts that match the sliding protrusions of the bearing plates are formed on the upper assembly surface and the lower assembly surface respectively, and inner friction surfaces that match the outer friction surface of the bearing plates are formed between the sliding concave parts and on both sides thereof.
