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 (). 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.

Device for controlling a motor-vehicle servo-assisted brake

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 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. A circuit for controlling current conduction in the MOSFET transistor is connected to the gate of the transistor and, each time it receives an activation signal, brings about an initial transitory stage in which a progressively increasing current is conducted through the transistor and in which the transistor is operating in the linear region of its characteristic, and a subsequent, or steady-state stage in which the transistor is operating in conditions of substantial saturation. An enabling circuit is connected to the second supply terminal to keep the MOSFET transistor non-conductive when the second supply terminal is disconnected and to supply an activation signal to the circuit for controlling current conduction when that terminal is connected to the voltage source.

Interface circuit between a direct-current voltage source and a circuit for driving a load, particularly for use in motor-vehicles

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.

End connection device for an operating cable, with system for ensuring correct assembly

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. The control unit is operable to carry out a process of learning and memorizing the actual engagement positions of the speed ratios or gears, which makes it possible to eliminate any operations for calibrating or adjusting the positions of the gears at the end of the assembly line.
