Supporting device for disk brake friction pads

A supporting device for a pair of friction pads in a disk brake system having a frame which straddles a disk rotating in tandem with the wheel and is fixed to a non-rotating member of a vehicle, and a caliper which is slidable in an axial direction of the rotating disk and set in the fixed frame, one end of each of the pair of friction pads being interlocked with the frame such that trailing ends of the pads slide in the axial direction of the rotating disk, the supporting device comprising:

• an anti-rattling plate positioned between the fixed frame and the friction pads;
• a connecting bar formed along a first side edge thereof on a first end of said anti-rattling plate;
• first and second sliding members each extending from opposing ends of said connecting bar so as to be positioned between the interlock of the fixed frame and a corresponding friction pad;
• an anti-slippage ledge formed on a second side edge of said connecting bar between said first and second sliding members, said anti-slippage ledge abutting into a recessed groove in the fixed frame formed so as to accommodate the rotating disk, said anti-slippage ledge being further formed so as to regulate sliding of the pair of friction pads in the axial direction of the rotating disk;
• first and second retaining arms each extending from opposing outer ends of said connecting bar and formed so as to engage outer side faces of the fixed frame with a clearance and formed to a width narrower than a width of the recessed groove of the fixed frame;
• and
• wherein said anti-slippage ledge and said first and second retaining arms are integrally formed with said connecting bar and said first and second sliding members, respectively.

• first and second sliding members each with an inner end and each extending form opposing ends of said connecting bar so as to be positioned between the interlock of the fixed frame and a corresponding friction pad;
• an anti-slippage ledge formed on a second side edge of said connecting bar between said first and second sliding members, said anti-slippage ledge abutting into a recessed grove in the fixed frame formed so as to accommodate the rotating disk, said anti-slippage ledge being further formed so as to regulate sliding of the pair of friction pads in the axial direction of the rotating disk;
• and
• first and second retaining arms each integrally formed with the extending from the inner end of a corresponding sliding member, each of said first and second retaining arms being further formed so as to lockingly connect with a corresponding side face of the fixed frame with a clearance and formed to a width narrower than a width of the recessed groove of the fixed frame thereby preventing displacement of the supporting device in a direction orthogonal to the axis of the rotating disk.

A disk brake system, comprising:

• a disk brake rotating in tandem with a wheel of a vehicle;
• a frame which straddles said rotating disk and is fixed to a non-rotating member of the vehicle;
• a caliper which is slidable in an axial direction of said rotating disk and set in said fixed frame;
• a pair of friction pads, one end of each of said pair of friction pads being interlocked with said frame such that trailing ends of said pads slide in the axial direction of said rotating disk;
• a supporting plate positioned between said fixed frame and said rotating disk;
• a supporting plate positioned between said fixed frame and said friction pads, said supporting plate including a connecting bar, first and second sliding members each with an inner end each extending from opposing ends of the connecting bar so as to be positioned between the interlock of said fixed frame and a corresponding friction pad, an anti-slippage ledge formed on a second side edge of the connecting bar between the first and second sliding members, and first and second retaining arms each integrally formed and extending from an inner end of a corresponding sliding member, wherein
• the anti-slippage ledge and said retaining arms are integrally formed as individual parts and said anti-slippage ledge abuts into a recessed groove in said fixed frame formed so as to accommodate said rotating disk, the anti-slippage ledge being further formed so as to regulate sliding of said friction pads in the axial direction of said rotating disk, and
• each of the first and second retaining arms is further formed so as to lockingly connect with a corresponding side face of said fixed frame with a clearance and formed to a width narrower than a width of the recessed groove of the fixed frame thereby preventing displacement of the supporting device in a direction orthogonal to the axis of said rotating disk.
