Patent ID: 7644809

Claim:
A spring member for disc-brake calipers, suitable for being mounted in a disc-brake caliper, the caliper being suitable for being arranged, in a fitted configuration, astride a brake disc rotatable about an axis defining an axial direction, said caliper comprising a space for housing at least one pad which extends predominantly in a tangential direction parallel to a braking band of the brake disc and perpendicular to the axial direction, the spring member being interposed between a lateral edge of a pad and reaction surfaces of the caliper so as to act resiliently on the pad, the spring member comprising a ‘U’-shaped portion suitable for forming a connection with a protuberance of the reaction surfaces which projects in the tangential direction into the housing space, a first resilient portion which extends substantially in a radial direction perpendicular to the axial and tangential directions, is suitable for acting on the pad in a tangential direction, and is operatively connected to the ‘U’-shaped portion, and a second resilient portion which extends substantially in the tangential direction, is operatively connected to the first resilient portion, and is suitable for acting on the pad in a radial direction, wherein the first resilient portion is inclined in a manner such that a first connection end of the first resilient portion, connected to the ‘U’-shaped portion, is in contact with reaction shoulders and a second connection end, connected to the second resilient portion, is arranged, in the tangential direction, further towards the interior of the housing space than the first connection end, the first and second resilient portions being a single body projecting from the first connection end of the first resilient portion so that, when the spring member and the respective pad are in a fitted configuration in the housing space of the caliper, the pad is acted on resiliently by the spring member both in a radial direction and in a tangential direction, whether or not a braking force is being applied; wherein the spring member comprises two limbs and a connecting arm between the limbs so that, when the spring member is in a fitted configuration on the caliper, each limb can act resiliently on a respective pad, the pads being arranged opposite one another in the axial direction; said limbs comprise, in the region of a portion attached to the connecting arm, a notch which can separate the connecting arm from a first substantially straight section for attachment to an upper surface of the ‘U’-shaped portion so as to permit resilient relative bending between the connecting arm and the first section of each limb.
