| 摘要 |
<p>The invention relates to an actuator (3) for a transmission system (4), comprising: an electric motor (12) comprising a rotor (14) and a stator (15), the rotor (14) being secured to a driving surface (16) and mobile about a rotational axis (X); a plurality of planetary rollers (17) having a surface (18) designed to cooperate with the driving surface (16) in such a way as to be driven by said surface (16) at least in rotation about said axis (X); and an abutment (20) for the transmission system (4), comprising: a driven surface (21) designed to cooperate with the surface (18) of the planetary rollers (17); and a bearing surface (22) designed to be applied to the transmission system (4), the bearing surface (22) being mobile in relation to the driven surface (21).</p> |
