摘要： 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 rolling 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 rolling four-bar linkage (10) to allow movement of the front wheels with respect to the rolling four-bar linkage (10). The rolling 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 and above the upper cross member (12) so as to carry a load above the upper cross member.

摘要： 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). In particular, this method is applied to a drive mechanism (1) comprising a pedal shift lever (12) and a quick-shifter device (5) that connects, directly or indirectly, the lever to the gearbox, where this device includes a rod (10) and first sensor means (SM0, SM1-SM2) that detect the variation of the tension state of said rod (10) following a gear shifting. The method according to the invention includes acquiring a first signal (S1) generated by said first sensor means and determining, based on said first signal, whether the rod is in a traction tension state or in a compression tension state. The method also includes acquiring at least a second signal (S2) generated by second sensor means (SM3) and determining, based on this second signal (S2), the gear engaged following said gear shifting and/or the direction of said gear shifting. Finally, the method includes determining the operative shift configuration of the drive mechanism based on the tension state determined in the step B) and the gear engaged and/or based on the direction of said gear shifting determined in the step D).

摘要： 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. This device comprises an actuation means (5) that, during gear change, exerts a predetermined force (S) in contrast to the force exerted by said return means (12) of the clutch assembly, wherein said predetermined force (S) is less than the force (F) generated by the return means (12) so as to cause a mutual slip of the elements (11A, 11B) of the clutch device (11) without said opening condition being reached. The operating device (21) is of hydraulic type and comprises a primary pump (22) operated by means of a control lever (23), wherein this primary pump (22) is hydraulically connected, through a primary hydraulic circuit (16), to a primary piston (24) acting on at least one of the elements (11A, 11B) of the clutch device (11) in opposition to the return means (12) so that, following an action on the control lever (23), the primary piston (24) exerts an action the elements (11A, 11B) determining the opening condition. According to the invention, the control device (6) comprises a secondary piston (25) connected to the primary piston (24), wherein the actuation means (5) exerts, directly or indirectly, the predetermined force (S) on the secondary piston (25), said predetermined force (S) being transferred to the primary piston (24) in opposition to the force (F) of the return means (12).
