摘要： A hydraulic shock-absorber comprises an outer cylindrical tube, an inner cylindrical tube defining with the outer cylindrical tube an annular chamber, a main piston slidably mounted in the inner cylindrical tube and dividing the inner volume of the inner cylindrical tube into an extension chamber and a compression chamber, both containing an incompressible damping fluid, a valve assembly mounted on a bottom wall of the inner cylindrical tube and comprising a first compression valve and a first intake valve, a cup-shaped body mounted in the inner cylindrical tube, inside the compression chamber, and an auxiliary piston rigidly connected to the main piston and configured to slide in the cup-shaped body at least during a final section of the compression phase of the shock-absorber. The shock-absorber further comprises a second compression valve configured as a non-return valve allowing the flow of the damping fluid only in the direction from a working chamber of the cup-shaped body towards a lower portion of the compression chamber.

摘要： The hydraulic stop member comprises: a cup-shaped body mounted in a compression chamber of the shock-absorber. A piston is mounted at an end of a rod of the shock-absorber so as to slide in the cup-shaped body when the shock-absorber is close to an end-of-travel position of the compression stroke. The cup-shaped body includes a side wall and a bottom wall which define, along with the piston, a working chamber where a damping fluid of the shock-absorber is compressed by the piston. A bypass conduit connects a working chamber with the portion of the compression chamber placed above a seal ring. A pressure relief valve keeps the bypass conduit closed as long as the pressure in the working chamber remains below a given threshold value and to open the bypass conduit, thereby allowing the discharge of the damping fluid from the working chamber to the compression chamber through the bypass conduit, when the pressure in the working chamber exceeds the threshold value.

摘要： The hydraulic shock-absorber comprises a hydraulic stop member having a cup-shaped body, which is adapted to be mounted in a compression chamber, and a plunger, mounted at an end of a rod of the shock-absorber so as to slide in the cup-shaped body when the shock-absorber moves towards the compression end-of-travel position. The cup-shaped body comprises a side wall and a bottom wall which define, along with the plunger, a working chamber in which a damping fluid of the shock-absorber is compressed by the plunger when the latter slides in the working chamber towards the bottom wall of the body. Axial channels are formed on the inner surface of the side wall of the body and allow the damping fluid to flow axially out of the working chamber when the plunger slides in the working chamber towards the bottom wall of the cup-shaped body. The axial channels extend parallel to a longitudinal axis (z) of the cup-shaped body and have a cross-section whose area decreases continuously along this axis (z) towards the bottom wall of the cup-shaped body.

摘要： The shock-absorber comprises: a cylinder containing a hydraulic working fluid; a piston slidably arranged in the cylinder so as to split the cylinder into two variable-volume working chambers, namely a first working chamber, or extension chamber, and a second working chamber, or compression chamber; an auxiliary conduit in fluid communication on one side with the first working chamber and on the other with the second working chamber; a train of permanent magnets slidably arranged in the auxiliary conduit so as to reciprocally move along the auxiliary conduit, dragged by the working fluid flowing between the first and second working chambers through the auxiliary conduit as a result of the reciprocating motion of the piston in the cylinder; and electric energy generating device for generating electric energy by exploiting the movement of the train of permanent magnets along the auxiliary conduit.

摘要： An apparatus and a method for managing the energy supplied to a low-voltage system of a vehicle. The low-voltage system includes a battery, which supplies the first voltage on a low-voltage bus. A system for charging the battery includes an alternator for supplying a charging voltage to the battery, and motor-vehicle loads supplied by the battery and/or by the alternator. A high-voltage system operates at a second voltage higher than said first voltage. The high-voltage system includes the vehicle energy-recovery stage. The second voltage is supplied through an intermediate energy-storage system and a DC-DC converter. A control module that carries out energy-management operations at least by the alternator. The second voltage of the DC-DC converter is regulated via a control procedure of a hysteretic type.

摘要： The damper and spring unit comprises a damper, a spring member extending coaxially to the damper, a bottom spring plate and a vehicle height adjustment device for adjusting the height of the vehicle from the ground. A first damper element is connected to a wheel carrier of the suspension and a second damper element is slidable relative to the first damper element along the longitudinal axis (z). The adjustment device is interposed between the first damper element and the spring member to change the linear position of the bottom spring plate, and a bottom end of the spring member, relative to the first damper element. A hydraulic linear actuator comprising a cylinder is secured to the first damper element and a piston drivingly connected for translation with the bottom spring plate along the longitudinal axis (z) of the damper between a bottom end-of-travel position and a top end-of-travel position.
