AI Technical Summary

Technical Problem

Existing disc brake devices with circumferential bridges face challenges in applying pad clips effectively due to interference issues, which affects the stability of the pressing force applied to the pads.

Method used

A pad clip made of a metal plate is designed to be circumferentially apart from the inner and outer bodies of the caliper, featuring a center bridge, end bridge, and circumferential bridge. It includes a body portion elastically supported between the center and end bridges, and pad pressing portions that press the outer peripheral edges of the pads inward, ensuring stable application of pressure.

Benefits of technology

The pad clip effectively applies a stable pressing force to the pads, even in disc brake devices equipped with circumferential bridges, thereby enhancing the braking performance and reducing the risk of interference issues.

Abstract

To provide a pad clip which can be applied to a disc brake device including a circumferential bridge and stably apply pressing force to a pair of pads.SOLUTION: A turn-in side pad clip 5 includes: a body 39 elastically supported between a center bridge 12 and a turn-out side end bridge 11; and a pair of pad pressing parts 40a which presses outer peripheral edges of a pair of pads 3 to the radial inner side. A radial outer surface of the body 39 is pressed to a radial inner surface of a turn-out side circumferential bridge 14 by elastic force of the pair of pad pressing parts 40a.SELECTED DRAWING: Figure 10
