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 transmission assembly for a hydrostatically or electrically propelled vehicle, comprising an input shaft, an output shaft, a first pair of gears and a second pair of gears, a synchroniser, a hydraulically operated actuator of the synchroniser which comprises a rod, and a hydraulic circuit for moving the rod, wherein the rod comprises an enlarged portion that is slidingly and sealingly housed in a respective portion of the seat so as to define two intermediate chambers. The actuator further comprises a contact element that is slidingly and sealingly housed in a relevant seat that is adjacent to the portion of the sliding seat so as to define a first end chamber, the contact element being able to move independently of the rod and defining an end point of the rod. A second end chamber is defined in an end of the rod that is opposite the enlarged portion.
