Electromechanical, active dual-redundancy, twin-motor actuator to operate a component of a vehicle

An electromechanical actuator (1) to operate a component of an internal combustion engine and/or of a vehicle comprising:

• a housing (2), which is obtained through a lower element (3) and a lid (4);
• a transmission, which is arranged inside the housing (2) and comprises an output shaft (9), which is provided with a first symmetry axis (X), and an intermediate shaft (18), which meshes with the output shaft (9) and is provided with a second symmetry axis (Y), which is transverse to the first symmetry axis (X);
• and
• a pair of electric motors (31, 32), which are also arranged inside the housing (2);
• wherein each one of the two electric motors (31, 32) causes the rotation of the output shaft (9) through the intermediate shaft (18), and wherein the two electric motors (31, 32) are provided with respective rotation axes (Z1, Z2), which are parallel to one another and transverse to the first symmetry axis (X);
• wherein the two electric motors (31, 32) are arranged side by side and are provided, at one of their axial ends, with respective gears (29, 30) arranged on opposite sides of a common toothed wheel (20) of the intermediate shaft (18) with which they mesh so that the gears (29, 30) transmit the motion from the corresponding electric motor (31, 32) to the same end of the intermediate shaft (18);
• and
• wherein at least one needle roller bearing is fitted on the output shaft (9) so as to lock the output shaft (9) in a radial direction and a plug (17) is placed to lock the output shaft (9) in an axial direction.
