Spot-type brake

A spot-type brake comprising a pair of friction elements cooperating with a movable support during braking to engage a rotor to be braked, the movable support being slidable relative to a fixed support, each of the pair of friction elements defining a profile in an axial section substantially the shape of a V whose bisectrix is substantially parallel to the axis of rotation for the rotor, characterized in that said rotor comprises a two-part assembly, the first part being engageable with radially outer portions of said pair of friction elements and the second part being engageable with radially inner portions of said pair of friction elements, said first and second parts forming a radial V for each part and an annular space therebetween, the radial V for said first part defining frusto conical surfaces approaching each other in a radially inward direction, the radial V for said second part defining frusto conical surfaces approaching each other in a radially outward direction, said movable support including connecting means extending into said annular space in order to engage one of said pair of friction elements and dispose the latter adjacent said first and second parts, and said fixed support extending through said annular space in order to oppose said one friction element.
