Abstract: A motorized drive device includes a housing, electric motor, drive wheel, first and second holding devices, first elastic return element, drive unit inside the housing, and switching mechanism. The drive unit includes a casing, the electric motor and the drive wheel. The drive wheel is supported on a rail running surface, by the first elastic return element. With the motor activated, the casing inclines inside the housing relative to a median plane of the housing. The switching mechanism drives a first guide wheel of the first holding device between first and second positions, in which the motorized drive device is mounted and dismounted, respectively, relative to the rail. In the first position with the electric motor activated, the drive wheel is supported on the rail running surface, by the first elastic return element which is supported on a wall in the housing and is rotated by the electric motor.

Abstract: An electromechanical actuator comprises a casing, an electric motor, a gearbox, a spring-applied brake (25), and a centring shaft (71). The brake (25) comprises a coil spring (48), a drum (49), an input member (50) and an output member (51). The output member (51) comprises a first bore (73). The shaft (71) is mounted inside the first bore (73) of the output member (51) and a bore of a sun gear (40) of a reduction stage (38) of the gearbox. The drum (49) comprises a shoulder (90). Furthermore, a planet carrier (66) of the reduction stage (38) is configured to bear against the shoulder (90) of the drum (49).

Abstract: Disclosed is an electromechanical actuator including a spring brake including a helical spring, a drum, an input member and an output member. The drum includes a friction surface configured to cooperate with at least one turn of the spring. The output member includes at least one lug. The lug includes a recess provided with at least a first bearing surface configured to cooperate with one of the first and second legs of the spring. The first bearing surface of the recess is inclined with respect to an axis of rotation of the brake at an angle of inclination of non-zero value.
