<p>Coupling device for gear transmissions for vehicles, comprising a rotary shaft (2) arranged vertically in a housing (1), which shaft is provided with a hinged lever (4) fixed by its upper end and arranged outside the housing (1), as well as a gear shifting lever (10) cardanically hinged to the housing above the rotary shaft (2) and at the vicinity of the axis (38) thereof. The coupling linkage between the rotary shaft (2) and the gear-shifting lever (10) is essentially comprised of a coupling shaft (5) housed adjacent to the housing in the longitudinal direction of the vehicle and at the vicinity of the axis (38) of the rotary shaft (2) as well as of a crank lever (7) housed at one end of said coupling shaft (5) in a substantially vertical axis (9). The gear shifting lever (10) is housed at the other end of the coupling shaft (5) ina substantially horizontal axis (12) and transversely with respect to the axes (7, 26, 32) of the crank lever (7), of the rotary shaft (2) and of the coupling shaft (5). Both lever arms (13, 20) of the crank levers (7) are coupled by means of cardan joints (14, 21) respectively with the articulated lever (4) of the rotary shaft (2) and with an articulated arm (22) of the gear shift lever (10).</p> |
