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.

Abstract: The present invention relates to a saddle-ride type vehicle comprising a clutch assembly (4), interposed between an engine (2) and a gearbox (3), which includes a clutch device (11) in turn comprising two clutch elements (one integral with the shaft of the engine and the other with the input shaft of the gearbox) and return means (12) that keep these elements (11A, 11B) in contact in a closure condition of the clutch. According to the invention, the clutch assembly (4) further comprises an operating device (21) of the clutch device that causes detachment of the elements (11A, 11B) of the clutch device up to an opening condition of the clutch assembly. This latter further comprises a control device (6) to limit the torque peaks during gear change.

Abstract: The present invention relates to a method for determining an operative shift configuration of a drive mechanism (1) of a gearbox (G) of a saddle-ride type vehicle (4).

The parking brake further includes a locking member (33) adapted to engage the inhibitor device (31) when actuated. The inhibitor device (31) is configured to prevent the engagement of the locking member with the inhibitor device when the inhibitor device rotates at a speed greater than a minimum speed, so as to prevent the application of the parking brake.

Abstract: A control system for an electrically-actuated, rideable saddle vehicle including an electric traction motor and a vehicle control system having two different speed acquisition systems. A first speed system includes a position sensor and controls power to the motor on a basis of a control signal, which is characteristic of torque selectively required by the electric motor. A second speed system includes Logic circuitry for estimating vehicle speed from estimated variations of a counter-electromotive force generated in the stator winding as a result of the rotor movement of the motor. The two systems allow optimizing control of the motor from both speed systems, or from that considered more reliable in a given operating condition, during operation of the vehicle. Illustratively, for low speeds, speed control may be based on sensor signals in the first speed system, while high speeds control may be based on the estimates from the logic system.
