DISC BRAKE HAVING A LATCH FOR LOCKING THE CONVERSION CARTRIDGE BY MEANS OF A LATCH

摘要

The invention relates to a disc brake comprising floating calipers and a brake piston controlled via a movement conversion cartridge (200) which includes a rear portion bearing against the bottom of the calipers and a control shaft extending through the bottom. The front portion of the cartridge bears against the brake piston. Said portion comprises a piston (240) provided with a plate (242) engaging with the plate (212) of the control shaft (210), wherein balls are positioned therebetween and engage with tracks in the form of ramps for converting the relative rotational movement of the plate (212) relative to the other (242) into a translation movement of the piston (240). The cartridge (200) is held in place in the recess (113) thereof by a cage (260) elastically attached to the wall of the recess. The plate of the piston (240) comprises longitudinal flutes (243) for receiving the branches (233) of a latch (230) which is rotatably locked in the caliper recess while leaving the conversion piston (240) to be freely translatable.
