Abstract
Brake motor with automatic adjustment, comprising a body (20) which incorporates a groove (62). A piston is mounted in this body and has a pivot (48) which guides the piston in the groove. A pawl (46) mounted at one end on the pivot (48) and applied elastically via a slope (64) against a portion (66) fixed relative to the body (20) stresses a toothed wheel (44) in terms of rotation when the relative axial movement between the body (20) and piston exceeds a predetermined value. The toothed wheel (44) integral with a nut causes the lengthening of a screw/nut system, thus ensuring automatic adjustment. The invention is used for braking motor vehicles.
