Abstract:
An arrangement for releaseably fastening an annular brake disc to a rotateable brake disc carrier which supports the brake disc to rotate together with the carrier, the arrangement comprising:the annular brake disc having an internal periphery, a plurality of driving protrusions facing radially inwardly from the internal periphery which are arrayed around the internal periphery and are separated from each other in the circumferential direction; the brake disc carrier having an external periphery, a plurality of external, axial grooves running axially on the external periphery of the carrier and also extending in the axial direction; ridges at the external periphery of the carrier defining the grooves in the carrier; the grooves in the carrier and the protrusions on the disc are respectively so positioned that the protrusions engage in the grooves; the circumferential widths of the protrusions and of the grooves are related such that a spacing gap is defined between a protrusion and one of the respective adjacent ridges defining the groove in which the protrusion is disposed; a spacing device removeably disposed in at least one of the spacing gaps, the spacing device being sized in the circumferential direction with respect to the spacing gap and with respect to the size and shapes of the driving protrusion and the respective groove in which the protrusion is disposed, to fix the brake disc relative to the carrier in the circumferential direction.
