Abstract

L’invention se rapporte à un porte-satellite comprenant un corps (19) et au moins un tourillon (12) agencé pour porter un pignon satellite (11) et assurer un guidage en rotation de ce pignon satellite (11). Le corps (19) de ce porte-satellite comprend un logement recevant le tourillon (12) de manière à former un ajustement avec jeu radial entre le tourillon (12) et le corps (19). Ce porte-satellite comprend au moins une butée axiale configurée pour limiter le déplacement axial du tourillon (12) par rapport au corps (19) au moins dans un sens de translation axiale. L’invention concerne aussi un actionneur de frein de parking électrique pour véhicule automobile comprenant un réducteur épicycloïdal ayant au moins un porte-satellite conforme à l’invention. Figure pour l’abrégé : Fig. 3The invention relates to a planet gear carrier comprising a body (19) and at least one journal (12) arranged to carry a planet pinion (11) and ensure rotational guidance of this planet pinion (11). The body (19) of this planet carrier comprises a housing receiving the journal (12) so as to form a fit with radial play between the journal (12) and the body (19). This planet carrier comprises at least one axial stop configured to limit the axial displacement of the journal (12) relative to the body (19) at least in one direction of axial translation. The invention also relates to an electric parking brake actuator for a motor vehicle comprising an epicyclic reduction gear having at least one planet carrier according to the invention.
