Patent ID: 7014018

Claim:
A vehicle braking device comprising a caliper provided with at least two opposing pistons mounted in a housing having fittings for mounting, in parallel planes, at least two brake pads controlled by said pistons to act on at least one disk, wherein: the caliper housing comprises two parallel sides, joined at each end by a respective transverse link in order to delimit a median opening for positioning of the pads; the pads have, at each of their upper ends, semicircular cut-outs formed from a transverse edge of a supporting element receiving a friction element supported and guided by shafts acting as slides; the shafts are engaged, over their whole length, in the thickness of the sides, and in approximately semicircular rectilinear indentations formed in the thickness of the respective transverse link, in an area where there is no deformation, in order to reduce significantly hysteresis due to friction between the pads and the housing; and wherein the sides have, approximately in their median parts, bosses for mounting, in pairs, of a transverse shaft for receiving a supporting element whose ends interact with and bear on the shafts acting as slides, said supporting element receiving, on both sides, a friction element, in order to delimit, in combination with the pads, two spaces for engagement of two parallel disks, the pistons being mounted in opposition and acting simultaneously on the pads with respect to the supporting element which is fixed with respect to translation on the transverse shaft.
