Abstract
A movement transmission device having a first assembly including a housing extending along a first axis, a second assembly configured to move in rotation and in translation along the first axis inside the housing, and a first elastic member. The first assembly includes a first axial stop and the second assembly includes a complementary first axial stop, a first axial clearance being formed between the first axial stop and the complementary first axial stop. The first elastic member is adapted to be deformed during translational movement of the second assembly along the first axis when an axial force greater than a first threshold is applied, the complementary first axial stop being axially supported by the first axial stop.
Claims10
A movement transmission device (30) intended for an actuator (18), the device (30) comprising:
- a fixed first assembly (100), comprising a housing (110) extending along a first axis (B);
- a second assembly (200) arranged in said housing (110) and extending along the first axis (B), the second assembly (200) being configured to move in rotation about said first axis (B) and to move in translation along said first axis (B), inside said housing (110);
- and
- a first elastic member (300) installed inside said housing (110);
- wherein the first assembly (100) comprises a first axial stop (121) and the second assembly (200) comprises a complementary first axial stop (221), the first axial stop (121) and the complementary first axial stop (221) being axially facing each other, a first axial clearance (J1) being formed between the first axial stop (121) and the complementary first axial stop (221),
- wherein the first elastic member (300) is able of being deformed during translational movement of the second assembly (200) along the first axis (B) in a first direction when an axial force greater than a first threshold is exerted by the second assembly (200) on said first elastic member (300), the first axial clearance being progressively reduced until the complementary first axial stop (221) is axially supported on the first axial stop (121).
