摘要： A transmission unit for self-propelled vehicles, comprising two pulleys, i.e., a driving pulley and a driven pulley, with variable pitch, connected to each other by a transmission belt, is provided with an engine start-up device with an actuation group acting downstream the driven pulley; such an actuation group causes, at start-up time, the jockey element to act on the transmission belt, for the purpose of recovering possible slack of the belt; furthermore, lock elements, disengageable by centrifugal force, are provided, which mutually constrain, at start-up time, the two half-pulleys which compose the driven pulley, for the purpose of preventing the belts from wedging themselves between the same half-pulley.

摘要： 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.

摘要： The present invention relates to a saddle-riding type vehicle (1) comprising a frame (2) extending mainly along a longitudinal direction (L) and comprising a front portion (2A), a central portion (2B) and a rear portion (2C). The vehicle comprises a powertrain connected to the frame (2) and comprising at least one electric motor (11) operatively connected to at least one driving wheel (9). The vehicle also comprises an electrical power supply assembly suitable for powering said electric motor (11) so as to allow the traction of the vehicle (1) and comprising at least one first pair of batteries (12, 12′) arranged on opposite sides with respect to a longitudinal center plane (a) of the vehicle (1), orthogonal to the axis of rotation of said at least one driving wheel (9). According to the present invention, each battery (12, 12′) is supported by a corresponding support (13, 13′) movable between a retracted position and an extended position, each support (13, 13′) being operatively connected to moving means which releases and/or causes the rotation of the support (13, 13′) itself around a corresponding axis of rotation (R, R′) to allow said supports (13, 14) to reach said extracted position.
