Abstract (en)
[origin: WO2019105771A1] An electromechanical actuator comprises a spring brake (15) comprising a helical spring (22), a drum (23), an input member (24), an output member (25) and a cap (33). The drum (23) comprises a housing (26) comprising an inner friction surface (27) configured to cooperate with at least one turn of the spring (22). The input member (24) comprises a driving tooth (31) extending between the input member (24) and the cap (33). The input member (24) or the cap (33) comprises a spacer (34) extending between the input member (24) and the cap (33). The input member (24) comprises a first element (54) for radial retention of the spring (22) that extends between the tooth (31) and the spacer (34) along a first side (C1) of the brake (15). In addition, the cap (33) comprises a second element for radial retention of the spring (22) that extends between the tooth (31) and the spacer (34) along a second side (C2) of the brake (15).
