Abstract:
A disk brake including a first axially-guiding and radially-retaining spring and a second axially-guiding and radially-retaining spring for positioning a corresponding first friction pad and a second friction pad with respect to a disk, said first and second friction pads each being defined by first and second radially-opposite ears with each ear being guided by said first and second axially-guiding and radially-retaining springs retained in a support, said support for said first and second said axially-guiding and radially-retaining springs consisting of a yoke having a first arm arranged opposite a first main face of said disk and a second arm located opposite a second main face of said disk in the opposite direction to said first main face, said first and second arms being connected by at least one bow-shaped element characterized in that said first arm has a first protruding part and a second part extending therefrom and said second arm has a first protruding part and a second part extending therefrom, each protruding part forming a right-angled parallelepiped with a square base with an axial groove on a top surface thereof that is parallel to the axis of said disk, and in that said first and second axially-guiding and radially-retaining springs each having a shape that in a side view looks like the number â€œ5â€  to define a first throat that rests on said first protuding part and a second throat that receives one of said first or second ears of said first and second friction pads, each of said first throats having a having an axial edge located in said axial groove of said first protruding part that bears on said top surface with considerable force to retain said first and second axially-guiding and radially-retaining springs on said protruding part, said axial edge being further defined by a first lug that extends into said axial groove to lock said first and second axially-guiding and radially-retaining springs onto said first proturding part such that a second lug on said second throat is free to move and provide a resilient force to hold said first and second ears against a common wall of said first and second throats.
