    摘要: The invention relates to a system for maintaining the level of a usable plane (2) of a vehicle, said system comprising at least one set of bellows (12) for supporting the usable plane and at least one level regulating device (17, 16, 70, 57, 32') for aerating and deaerating the bellows (12). According to the invention, at least one control unit (34, 34') is used to activate or deactivate the level regulating device (17, 16, 70) and at least one hydraulic cylinder (7) is used to support the usable plane (2) and can be changed from at least one first operating state to a second operating state by means of the control unit (34, 34'). When the hydraulic cylinder (7) is in the first operating state, pressure changes caused in the hydraulic cylinder (7) by loads on the usable plane (2) can be compared, and when the hydraulic cylinder (7) is in the second operating state, pressure changes caused in the hydraulic cylinder (7) by loads on the usable plane (2) influence the control unit (34, 34') in such a way that the at least one set of bellows (12) can be aerated or deaerated.

    摘要: A wheeled vehicle (1) is provided with an axle (17) that oscillates about a longitudinal axis (19). The vehicle (1) is moreover provided with a bottom chassis (2); a top chassis (5), which is able to turn with respect to the bottom chassis (2) about a vertical axis (11) and which carries an operating arm (9); and two hydraulic cylinders (20), which can be activated by a control circuit (28) for blocking oscillation of the axle (17) with respect to the bottom chassis, (2) about the longitudinal axis (19). The vehicle (1) has a first sensor (46) designed to detect the angular position of the arm (9) about the vertical axis (11), and a second sensor (35), designed to detect a condition of braking of the vehicle (1). The control circuit (28) is able to block the cylinders (20) and hence the axle (17) automatically when the vehicle (1) is braked by the driver or when the arm (9) exits from an angular safety range (A).
