Actuator with two motors, a differential reducer and a torque limiter

Actuator comprising:

• two drive motors (14A, 14B),
• an output member (22),
• a differential reduction gear (16) having straight-cut teeth which is interposed between the two motors (14A, 14B) and the output member (22), the differential reduction gear (16) comprising:
• two sun pinions (30A, 70A, 30B, 70B), each sun pinion being rotatably coupled to a drive motor (14A, 14B),
• an output shaft (40), about which the axes of the sun pinions (30A, 70A, 30B, 70B) are rotatably mounted,
• a planet-carrying drum (60) which is connected to the output shaft (40) in order to be rotatably driven,
• at least one pair of planet pinions (64A, 64B) which are carried by the planet-carrying drum (60) and which are mounted so as to rotate about themselves, each planet pinion (64A, 64B) being engaged with a sun pinion (30A, 70A, 30B, 70B), the associated planet pinions (64A, 64B) of the same pair being engaged with each other,
• torque limiter (18) which is interposed between the two motors (14A, 14B) and the output member (22), characterised in that the torque limiter (18) brings about the connection between the planet-carrying drum (60) and the output shaft (40), which torque limiter (18) is arranged between the two sun pinions (30A, 70A, 30B, 70B) on the axis of the output shaft (40).
