Actuator for automobile mechanical gearbox comprises electric motor linked to speed reducer connected to control shaft by kinematic link

摘要

Selection of the gears requires the translation or rotation of a gearbox control shaft (1) in order to activate the forks (5). Selection movement of the shaft is linked to an engagement movement of the selected gear by first and second motors connected to a control unit under the control of the driver. The first motor comprises a direct current electric motor (6) linked to a speed reducer (7) connected to the shaft by a kinematic link (8-12).
