Braking bands of discs for disc brakes, capable of both the efficient discharge of heat and of high mechanical performance at low weight are provided.

Braking band and disc for a disc brake

A disc brake caliper comprising a suspension side portion, facing an associable suspension to support said caliper, a wheel side portion facing a wheel being rotatably integrally associable to a brake disc, said wheel side and suspension side portion comprising cylinders suitable to house pistons facing pads for breaking the brake disc, and being connected by at least one connecting bridge extending astride the brake disc. The caliper comprises at least one casing being associable to a side surface of said caliper opposite a housing recess of the brake disc, such as to define a duct extending between said suspension side and wheel side portion to convey a cooling air steam, near thrust portion of the pads being affected by the relative pistons.

Disc brake caliper with a cooling duct

The disk includes a bell (), an annular braking band () and coupling () between bell and band. The bell () is provided with a plurality of openings () along its periphery, the band () is provided in the vicinity of its inner edge with a corresponding plurality of slots () having parallel sides in the radial direction, while the coupling includes a plurality of dragging elements (), each of which engages with an opening () of the bell and a slot () of the band to create a tangential constraint between bell () and band (). In order to reduce the specific pressure between the dragging elements () and the slots (), each of the dragging elements () includes a part () with two parallel opposite faces () that engage with the parallel sides of the slot () in such a manner as to be in contact with them.
