摘要： A suspension assembly for a vehicle axle. The assembly comprises a support structure, a housing element rotatably connected, about a transverse axis, to a support element in which the support structure is configured in a such a manner that it can rotate in relation to the support element about the longitudinal axis of the vehicle and is secured to the main chassis of the vehicle by a pair of hydraulic cylinders. The support structure comprises a pair of main guides, which can be fixed to the main chassis and a rolling element which slides between the pair of main guides and a contact element with a pair of further guides, the contact element operatively associated with the pair of further guides so as to come into contact with one of the further guides following a rotation about the rolling element.

摘要： A final transmission for agricultural and industrial motor vehicles. The transmission includes a differential unit having a support structure and a differential that transmits an input motion to an intermediate transmission shaft and a transfer unit with a final shaft that transmits the motion to the driving wheel. The final transmission also has a toothed output wheel integral to the intermediate transmission shaft which engages respectively with an internally toothed crown wheel and with an intermediate toothed wheel, and also at least one toothed support wheel which engages with the internally toothed crown wheel and with the intermediate toothed wheel.

摘要： A tool lifting apparatus for gardening vehicles such as lawn mowers or the like, of the type that comprises a lever-type frame, which supports the tool and is associated with hydraulic-cylinder lifting actuators, coupled between the frame and the vehicle chassis. The lever-type frame is coupled to the vehicle chassis to perform oscillations with respect to a longitudinal axis. The lever-type frame defines a third-class lever in which the lever fulcrum is arranged to the rear of, and parallel to, the front axle of the vehicle and to the rear of the actuators.

摘要： A gearbox (1) for agricultural and industrial motor vehicles comprises an input shaft (2) and an output shaft (3), a first clutch (12) and a second clutch (13) arranged in a position between the first and second transmission shafts (16, 17), the first and second transmission shafts both being hollow. The gearbox further comprises a first intermediate shaft (20) and a second intermediate shaft (21), the first intermediate shaft extending coaxially inside the second intermediate shaft. A first engaging device (22) is capable of selectively connecting the first intermediate shaft to the output shaft, a second engaging device (23) is capable of selectively connecting the second intermediate shaft to the output shaft and a third engaging device (24) alternately connects the second intermediate shaft to the first intermediate shaft or to the output shaft. The first engaging device and second engaging device are coaxial with the output shaft. The third engaging device is coaxial with the first and second intermediate shafts and is interposed in an axial position between the first and second engaging devices.
