Floating calliper disc brake

摘要

Even in the case of moderate braking powers, the brake linings of floating calliper disc brakes wear down parallel to one another but obliquely to the front faces of the brake disc and, in the direction of rotation of the brake disc corresponding to forward travel, the outer brake shoe supported by the brake calliper wears more heavily at the side where the brake disc emerges from the brake calliper and, correspondingly, the other brake shoe wears more heavily at the side where the disc enters the brake calliper. This necessitates frequent changing of the shoes. In order, therefore, to increase the life of the brake shoes and to even out their wear, it is proposed to give the rearward part of the brake calliper (rearward in relation to the direction of rotation of the brake disc in forward travel) a lower bending stiffness in certain areas than the forward part (forward in relation to the said direction of rotation).
