DISC BRAKE PROVIDED WITH A MOVEMENT-CONVERTING CARTRIDGE

摘要

A disc brake comprising a floating stirrup and a brake piston controlled via a motion conversion cartridge (200) comprising a rear part pressed against the bottom (114) of the housing (113) in the stirrup (100) and a control shaft (220) passing through the bottom. The front part (260) of the cartridge is pressed against the brake piston. It comprises a piston (270) provided with a plate cooperating with the plate of the control shaft (220) with the interposition of balls cooperating with tracks in the form of ramps to transform the relative rotational motion of one plate relative to the other into a translational motion of the piston (270). The cartridge (200) is held in place in its housing (113) by a cage (290) elastically attached to the wall (117, 118) of the housing (113). The piston (274) comprises longitudinal ribs (174) that fit in longitudinal grooves (119) produced in the wall of the housing (113) and thus ensuring the blocking of the rotation of the conversion piston (270) while allowing its translational motion.
