摘要:
An electric generator device comprising a panel (2) bearing one or more electric generating machines (3) each including a stator and a rotor concentric and substantially co-planar. The rotor is supported in rotation by the stator and presents a central part bearing one or more blades (11) of a fan (12). A flow of fluid causes the fan (12) and in consequence the rotor (R) to rotate. The rotor bears along its periphery a plurality of magnetic poles (P) whose magnetic fields link with windings (A) borne by the stator, for the induction of an electric current in the windings. The rotor is supported in rotation within the stator through magnetic means of support (9).

A seat assembly (1) for a motor vehicle is provided with a sitting portion (7) and a backrest (8), which is able to rotate about a horizontal axis (11), orthogonal to a longitudinal direction (12) of advance of the motor vehicle, between a raised position and a position where it is folded down against the sitting portion (7); the seat assembly (1) is provided with an articulated quadrilateral (20) made up of at least one front connecting rod (21) and at least one rear connecting rod (22) hinged to the sitting portion (7) about respective first axes (25, 26) and to a supporting base (17) about respective second axes (29, 30); the sitting portion (7) is movable backwards, considering the longitudinal direction (12) of advance, from a first position, in which the sitting portion (7) defines a sitting place for a passenger, to reach a rest position, in which the first axis (25) of one of the connecting rods (21, 22) is lower than the corresponding second axis (29).

摘要:
A motor-vehicle component, such as for example a fuel tank, or a pipe for the supply of fuel to the engine of the motor vehicle, or a motor-vehicle seat, or the bumper, has a structure at least partially made up of polymeric nanocomposite material containing carbon nanotubes. Associated to the structure are two electrical terminals, and carbon nanotubes are arranged so as to create a continuous electrical connection between said terminals. Electronic control and processing means are connected to said terminals in such a way as to detect the variation in the electrical resistance of the structure made of polymeric nanocomposite material containing carbon nanotubes as its strain varies. It is thus possible, for example, to obtain a signal indicating the degree of filling of the tank, or the pressure existing within the pipe, or the presence of an occupant on the seat or his posture, or pressures and/or impact to which the bumper is subjected.
摘要:
A spot welding head is described wherein an electrical conductor (8) for connection of one electrode (2) connection to an electric transformer is guided into a tubular sheath (7) whose ends are rigidly connected to the rear ends of the supporting bodies (4) of the electrodes (2). This tubular sheath defines a substantially stiff loop portion which is configured and arranged so as to be substantially parallel and facing the annular path defined by the two electrodes (2) and the supporting bodies (4) thereof, in such a way that the two magnetic fields, one generated by electromagnetic induction caused by electric current flowing through the electric conductor (8) placed into the loop-shaped sheath (7), and the other generated by electromagnetic induction caused by electric current flowing through the electrodes and the supporting bodies thereof, substantially cancel each other out or anyway generate an overall magnetic field which is sensibly reduced and located forwardly with respect to the rear end of the welding head or anyway spaced forwardly away from the operator's body.
摘要:
A discrete step rotary actuator (1) comprises a stator (2), a rotor (3) and at least an actuating element (10) made with a shape memory active material, the actuating element (10) having a first portion (11) anchored to said stator and a second portion with a terminal element (12). The rotor has a sequence of seatings (14) arranged as a circumference, into which the terminal element (12) can engage in a sequential way. Elastic means (13) placed between the actuating element (10) and the stator (2) induce the shift of the terminal element (12) between two consecutive seatings (14), during the passage of the active material from its shortened to its extended configuration. The passage of the active material from the extended configuration to its shortened configuration imparts the rotor (3) a rotation couple with respect to the stator (2).
摘要:
An actuator comprises an elongated shape-memory element (5) wound around a first element (2) and having one first end (5a) connected to the first element (2) and one second end (5b) connected to a second element. Heating means are provided for heating the shape-memory element (5) in order to obtain a displacement of one of the ends (5a, 5b) thereof. The elongated shape-memory element (5) is guided so that it can slide within a closed channel made of a material having a low coefficient of friction, for example defined by a sheath (4).
