Abstract: The motor vehicle comprises two front steering and rolling wheels (4, 4?) and at least one rear rolling wheel (9). The motor vehicle comprises a roll four bar linkage (10) connected to a frame (2A-2B) and which supports the front steered wheels (4, 4?). A suspension group (71, 71?) is interposed between the front wheels (4, 4?) and the roll four bar linkage (10) to allow movement of the front wheels with respect to the roll four bar linkage (10). The roll four bar linkage (10) comprises: a lower cross member (11) and an upper cross member (12) hinged to the frame to pivot around first roll axes (101, 101?); and a right upright (21) and a left upright (21?) hinged to the cross members (11, 12) so as to rotate around second roll axes (212, 212?, 221, 221?) parallel to the first roll axes (101, 101?). The lower cross member (11) extends along a longitudinal direction between the front wheels and beyond said front wheels to form a loading surface.

Abstract: An airbag system (1) for a powered saddle-ride type vehicle (100) is provided. The system comprises a housing (2): an airbag (6) arranged in said housing (2); and an inflator (7). The housing (2) is elongated and is configured to face the driver, and the housing (2) is configured to be fixedly mounted to a leg shield (102) next to the steering column (101) of the vehicle (100) in an area between handlebars (104) of the vehicle and a foot support (105) of the vehicle. The elongated housing (2) is configured to be mounted in a substantially horizontal direction, transverse to a longitudinally extending centreline (CL) of the vehicle (100). The inflator (7) is configured to allow the airbag (6), in the event of an activation signal, to inflate and deploy symmetrically on opposite sides of the longitudinally extending centreline (CL) of the vehicle (100) to thereby fill an available space between the vehicle and the driver's pelvis, abdomen, thorax and head area.

Abstract: A clutch (1) includes a housing (3) connected to a drive input member (5). First friction discs (7) are mounted in the housing and rotate therewith. Second friction discs (9) are mounted on a driven member (11). A pressure plate (13) is elastically stressed toward the driven member to compress the first and the second friction discs (7, 9) against one another. Cam profiles (31, 33) integral with the driven member and with the pressure plate, generate a thrust to move the driven member and pressure plate away from each other when it is necessary to reduce the pressure exerted by the pressure plate on the first and second friction discs. An angular stroke limiter limits the relative rotation between the driven member and the pressure plate and thereby limits the movement of the pressure plate away from the driven member).

An electronic control unit of the vehicle co-acts with the mobile device by means of an electronic interface, so as to provide the mobile device with information relating to the operation of the vehicle. In this way, the mobile device provides an integration of the on-board instruments of the vehicle, which completes the instruments available on the dashboard.

Abstract: The motor vehicle (1) includes a rolling forecarriage (3) and a non-rolling rear carriage (5). The forecarriage is connected to the rear carriage by a linkage system (23) that includes a four-bar linkage defining a roll axis that remains in a fixed position and on the supporting surface (S) of the motor vehicle (1) when the motor vehicle performs a roll movement.

Abstract: The saddle-riding motor vehicle (1; 107; 207) comprises a rear driving wheel (5; 105; 205) and a front steered wheel (7; 107; 207). The front steered wheel (7; 107; 207X, 207Y) is connected to a rotatable arm (9; 109; 209X, 209Y) provided with a rotary motion about a steering axis (A-A). A wheel support (37; 137) is connected to the rotatable arm (9; 109; 209) with the interposition of a suspension (17; 117; 217X, 217Y) comprising a shock absorber (22; 122).

Abstract: A camshaft for a multi-cylinder internal combustion engine with poppet valves, comprising a main body, which is rotatable with respect to a first rotation axis, a first disk and means of the hydraulic type for varying the timing of said first disk with respect to said main body.

Abstract: A combustion engine for a vehicle includes a first centrifugal device for varying timing of a first plurality of suction or relief valves with respect to the drive shaft. A driving disc is mounted idle on a first camshaft which controls the valves, and at least one driven disc is integral with the camshaft. Drive elements for transmitting motion from the driving disc to the driven disc are interposed between the two discs causing a relative rotation of the driven disc with respect to the driving disc when the rotation speed of the discs exceeds a predetermined threshold. A distribution system connects the drive shaft with the driving disc so as to cause the rotation thereof. A second gear meshes with a first gear so that rotation of the driving disc mounted on the first camshaft causes the rotation of the second camshaft to control other valves of the engine.
