A device for the adjustment of the attitude of a motor vehicle and coordinated adjustment of the bumper clearance, the device comprising: - a cylindrical body, which includes a first radially projecting flange, the flange being adapted to form an upper abutment of a main spring of an automotive suspension, the cylindrical body defining a first chamber, axially lower, and a second chamber, axially upper, the second chamber is hermetically sealed above by a lid and is configured to be placed in fluid connection with the outside of the cylindrical body by means of a through hole in the cylindrical body, the first and second chambers (14a, 14b) being fluidically decoupled by a septum, axially interposed between the first and second chambers (14a, 14b); - a bumper, slidably received in the first chamber of the cylindrical body and adapted to form a limit stop for the oscillation of the sprung mass of the vehicle when the latter approaches the unsprung mass of the vehicle; characterised in that the device comprises - a primary actuator, comprising: - a primary cylinder, slidably received in the second chamber of the cylindrical body, the primary cylinder being axially movable in response to the inlet or withdrawal of fluid into/from the second chamber, and identifies at the inside thereof a third chamber, in fluid connection with the second chamber; and - a primary rod, axially passing through the septum and connected at its opposite ends respectively to the primary cylinder and to the bumper, the primary rod being adapted to cause the bumper to slide in the first chamber in the same direction as the sliding of the primary cylinder in the second chamber; the device further comprising a secondary actuator, which includes: - an auxiliary piston, slidably received in the third chamber of the primary cylinder, the auxiliary piston being configured to move axially with respect to the primary cylinder in response to the inlet or withdrawal of fluid into/from the third chamber; and - a secondary rod, axially passing through the lid and connected at a first end to the auxiliary piston, the opposite end of the secondary rod being adapted to be connected to the sprung mass of the motor vehicle. - a cylindrical body, which includes a first radially projecting flange, the flange being adapted to form an upper abutment of a main spring of an automotive suspension, the cylindrical body defining a first chamber, axially lower, and a second chamber, axially upper, the second chamber is hermetically sealed above by a lid and is configured to be placed in fluid connection with the outside of the cylindrical body by means of a through hole in the cylindrical body, the first and second chambers (14a, 14b) being fluidically decoupled by a septum, axially interposed between the first and second chambers (14a, 14b); - a bumper, slidably received in the first chamber of the cylindrical body and adapted to form a limit stop for the oscillation of the sprung mass of the vehicle when the latter approaches the unsprung mass of the vehicle; characterised in that the device comprises - a primary actuator, comprising: - a primary cylinder, slidably received in the second chamber of the cylindrical body, the primary cylinder being axially movable in response to the inlet or withdrawal of fluid into/from the second chamber, and identifies at the inside thereof a third chamber, in fluid connection with the second chamber; and - a primary rod, axially passing through the septum and connected at its opposite ends respectively to the primary cylinder and to the bumper, the primary rod being adapted to cause the bumper to slide in the first chamber in the same direction as the sliding of the primary cylinder in the second chamber; - an auxiliary piston, slidably received in the third chamber of the primary cylinder, the auxiliary piston being configured to move axially with respect to the primary cylinder in response to the inlet or withdrawal of fluid into/from the third chamber; and - a secondary rod, axially passing through the lid and connected at a first end to the auxiliary piston, the opposite end of the secondary rod being adapted to be connected to the sprung mass of the motor vehicle.
