Title: ACTUATOR WITH HYBRID ACTUATION FOR A FORCE FEEDBACK INTERFACE
Abstract:
An actuator for a force feedback interface comprising a shaft constrained to rotate with an interacting member of said interface, an electric motor rotating the shaft (3) in a clockwise direction and in an anti-clockwise direction, a first free-wheel device (4) mounted on the shaft (3) and a first braking system (8) capable of braking the rotation of the shaft (3) via the free-wheel device (8), a second free-wheel device (6) mounted on the shaft (3) opposite the first free-wheel device (4), a second braking system (10) capable of braking the rotation of the shaft (3) via the second free-wheel device (6) in a direction opposite that of the first braking system (8). The motor can apply an active load to the shaft (3) in the opposite direction to that of the braking force.
