Mechanical actuator cartridge for a motor vehicle brake

A mechanical actuator cartridge (22) for a motor vehicle brake, comprising:

• a cartridge body (24) with an overall shape exhibiting symmetry of revolution about an axis (X),
• a rotary control plate (28), housed in the cartridge body (24),
• a push plate (30), housed in the cartridge body (24), collaborating with the control plate (28) via means (20) that convert the rotational movement of the control plate (28) into a translational movement of the push plate (30),
• elastic means (38) of compressing the push plate (30) towards the control plate (28), and
• a cage (40) for holding the elastic means (38), the elastic means (38) extending between a first seat (38A) borne by the cage (40) and a second seat (38B) borne by the push plate (30),
• in which:
• the cartridge body (24) comprises at least one projection (42) for attaching the cage (40) to the body (24), and the cage (40) comprises at least one axial tab (44) comprising an attachment orifice (46) capable of collaborating with the attachment projection (42) to attach this cage (40) to the cartridge body (24),
• the cage (40) is capable of rotational movement about the axis (X) of the cartridge body (24), between an attachment position in which the attachment orifice (46) collaborates with the attachment projection (42), and a release position in which the cage (40) is released from the body (24), and
• the cartridge body (24) comprising at least one first circumferential limit stop (50) for limiting the rotation of the cage (40), the axial tab (44) of the cage (40) being capable of collaborating with the first limit stop (50) when the cage (40) is in its release position,
• characterized in that the cartridge body (24) comprises a ramp-forming projection (60), adjacent to the first limit stop (50), such that when the cage (40) is in the release position, the axial tab (44) rests radially both against the attachment projection (42) and against the ramp-forming projection (60).
