Abstract: A control device includes an elongated mechanical transmission member (10; 110) interposed between the gearbox and a control member (100) for transmitting to the gearbox the commands imparted through the control member, in such a manner that the gear engaged by means of the gearbox is linked to the linear position of the transmission member (10; 110). The device is provided with a position sensor (26; 126) including a movable reference element (28; 128), the movement of which is univocally determined by the movement of a rigid end portion (14; 114) of the transmission member (10; 110), and a stationary detection element (30) for detecting the position of the reference element (28; 128).

Abstract: A quick-fit anchoring device for anchoring a sheath of a control cable to a mounting bracket is disclosed, which has a slot shaped generally as a U opening to a side of the mounting bracket, wherein the slot comprises a receiving portion of circular shape which is closed along an arc of circumference extending more than 180 degrees and less than 360 degrees so as to define an opening the width of which is smaller than the diameter of the receiving portion. The device comprises a hollow body adapted to be fixed to the sheath, a collar mounted on the body coaxially therewith and rotatably relative thereto about an axis of rotation coinciding with its own axis, and a spring interposed between the body and the collar.

Abstract: The device includes first and second elements which are intended to be rigidly connected each to a respective length of an elongated mechanical transmission member, such as a push-pull cable, a rod or a bar, and are slidably arranged relative to each other in the axial direction of the transmission member. A locking member is radially movable between a locking position, in which it drivingly connects the two elements for translation with each other, and a unlocking position, in which it disconnects the two elements from each other, thereby making them free to translate relative to each other. A cam member is free to translate axially relative to the first and second elements and has at least one cam surface which cooperates with the respective locking member so as to keep this latter in the locking position up to the predetermined travel value and to move it into the unlocking position in case of travel values higher than the predetermined travel value.

Abstract: The device (10) comprises an electric motor (12), a reduction gear (14), a shaft (16) operable by the motor (12) via the reduction gear (14), and a drum (18) mounted on the shaft (16) so as to be connected for rotation therewith but free to slide axially relative thereto. The drum (18) has on its cylindrical lateral surface a first groove (20) in which first studs (22) drivingly connected for translation each with a respective shift fork (24) are guided, whereby the rotational movement of the drum (18) is converted into a translational movement of the studs (22), and hence of the forks (24), to bring about the engagement of the gears. The drum (18) also has a second groove (40) in which a second, axially stationary stud (42) engages.

Abstract: The device comprises: an actuator unit arranged to apply a tension force on a pair of operating cables provided with a sheath; and a force sensing unit for providing a signal indicative of the force applied the sheath by either of the two operating cables (12a). The force sensing unit comprises: a pack of Belleville springs coupled to an end portion of the sheath and arranged to deform as a result of the tension force applied by the actuator unit on the operating cable; and a Hall position sensor for detecting the displacement of the end portion of the sheath as a result of the deformation of the pack of springs.

Abstract: An interface circuit is described for use between a direct-current voltage source and a circuit for the pulsed driving of a load such as an electric motor, in parallel with which at least one high-capacitance capacitor is connected, the interface circuit comprising a MOSFET transistor connected to a control circuit suitable for driving the transistor in accordance with predetermined procedures. The interface circuit comprises a first supply terminal and a second supply terminal which are intended operatively to be connected to the voltage source, permanently and temporarily, respectively.

Abstract: The device, suitable for connecting one end of an operating cable to a control member, particularly a control lever of a vehicle gearbox, includes: an outer body to be attached to the operating cable, having a through opening; and a bush arranged to be inserted into the through opening of the body to be locked inside it in a final assembled position and having a snap-action spherical seat for receiving a ball head of a pin to be connected to the control member. The spherical seat is provided with an elastically deformable element formed integrally with the bush and extending from the top of the seat in such a way as to elastically oppose the insertion of the ball head into the seat.

Abstract: The device, for connecting an end of a control cable to a control member, in particular to the gearshift lever of a motor-vehicle gearbox, includes: an outer body connectable to the control cable and having a through aperture; a bush insertable into the through hole of the body to be releasably locked in an assembly position; and a cover for closing the through aperture at the axially opposite side to that in which the bush is insertable. The bush is provided with resilient engagement means for cooperating with respective retaining members on the body so as releasably to lock the bush in the assembly position, and cam portions formed in one piece with the resilient engagement means.

Abstract: The system is operable to control a robotized gearbox which includes control levers which can be displaced along at least one working line along which a plurality of nominal operating positions are defined which correspond to the speed ratios or gears and to a neutral position. The control system includes electro-mechanical actuators coupled to the control levers and operable to displace them along the said at least one working line, and an electronic control unit operable to control these actuators to operate in a predetermined manner, so as to position the control levers selectively in one of the operating positions. The control levers have associated sensors operable to supply the control unit with signals which together indicate that the levers have reached predetermined positions along the said at least one operating line.
