Patent ID: 7344007

Claim:
A disk brake with a brake caliper comprising a brake disk, a sliding member which can be displaced in a vertical manner in relation to the surface of the brake disk in the brake caliper and can be engaged against the brake disk, and a clamping device comprising a rotary lever which can rotate around a rotational axis to turn in a rotational surface running vertical to the surface of the brake disk, and the rotary lever is equipped on its end turned away from an activation end with a bearing surface domed outward that is cylindrical and surrounds the rotational axis and, the rotary lever further comprises a control surface that is situated radially opposite and eccentric to the bearing surface and is domed inward in concave manner, and the clamping device further comprises a rotational body with rotary capacity in contact with the control surface, wherein every element of the control surface has a curvature radius greater than the radius of the rotational body, and the construction unit consisting of the rotary lever and rotational body is positioned between the sliding member and a cylindrical supporting surface of the brake caliper in contact with it, in such a way that, when the rotary lever pivots in a radial segment bearing, by means of reciprocal displacement of the rotational body and the rotary lever, the sliding member is displaced so that the position of the rotational axis of the rotary lever changes during the displacement of the sliding member.
