Radial spring for a disk brake pad and brake pads and brakes provided with such radial springs |
摘要 |
A radial spring for a disk brake pad and brake pads and brakes provided with such radial springs, in which the radial spring is for the lug of a brake pad. The spring includes a clamp and a supporting loop. The clamp is formed of a straight arm, an undulating bottom, and an arm in the shape of a Z, followed by the loop connected by a bend, followed by a bend with a large radius of curvature connected to the pad terminated by a turn that is almost at a right angle to the extremity of the pad. |

1. A radial spring for use in a brake pad in which the radial spring is slid transversely over a lug of a disk brake pad, comprising:
a radial spring arrangement formed of a ribbon of spring steel, having arms for attachment on the lug and a support portion for sliding against a lower surface of a housing of the arm of a yoke; wherein a portion of the radial spring is in the shape of a clamp to straddle the lug of the brake pad, extended by a supporting loop forming a pad that slides in the yoke housing, wherein the clamp has a stationary, straight arm having a flared extremity that is pressable against a face of the lug, followed by a segment forming a bottom of the clamp, and a movable arm connected to the bottom by an elastic hinge and closing the opening of the clamp, wherein the supporting loop forming the pad terminates in a turn and is connected by a double bend to the movable arm to elastically circumvent the bottom and come before the straight arm via the turn, wherein the double bend exhibits a first bend having only a first radius of curvature and a second bend having only a second radius of curvature and into which the first bend directly transitions, wherein no intervening segment that includes a straight section is present between the first bend and the second bend, and wherein each of the first and second bends lacks a straight segment, wherein the pad forms a lever that, elastically brought against the bottom, enlarges the opening of the clamp. |
