DISC BRAKE OF A VEHICLE FOR GENERATING STABLE BRAKING POWER BY GENERATING UNIFORM FRICTION FORCE WHOLE OVER A LATERAL SIDE OF THE DISC BRAKE AND ACCORDINGLY REDUCING JUDDER BY PRESSING A RING-SHAPED PAD BY PLURAL CYLINDER UNITS AND IMPROVING STRAIGHT TRAVELING AND OPERATION STABILITY OF THE VEHICLE BY POSITIONING A SUSPENSION BALL JOINT CLOSELY TO THE DISC BRAKE

摘要

PURPOSE: A disc brake of a vehicle is provided to reduce judder generated in braking by supplying uniform pressurizing power to a brake disc and to increase straight traveling and operation stability of the vehicle by positioning a suspension ball joint closely to the brake disc by plural cylinder units arranged around a ring-shaped pad. CONSTITUTION: A disc brake of a vehicle is composed of a ring-shaped pad(3) for pressurizing the whole lateral surface of a brake disc(1); a plurality of cylinder units(5) separated and arranged on the circumference formed by the ring-shaped pad to press the ring-shaped pad to the brake disc by hydraulic pressure; a caliper housing(7) connected with a suspension ball joint(9) to cover the outside of the pad and the brake disc and support the cylinder units; and a reinforcing plate(11) interposed between the pad and the cylinder unit.
