Abstract:
The system includes: a first pair of hydraulic linear actuators between a vehicle body and a respective rear wheel such that extension and compression the actuators causes increase and a decrease, respectively, in the height of the body from the ground at the rear axle; a second pair of actuators between the body and a respective front wheel such that extension and compression of the actuators causes increase and a decrease, respectively, in the height of the vehicle body from the ground at the front axle; a supply unit for generating a flow of fluid under pressure; a tank; a hydraulic circuit connecting the pairs of actuators, supply unit, and tank; and a flow controller arranged to control the fluid between the pairs of actuators such that, during raising or lowering of the vehicle body, the height at the front axle is always less than that at the rear axle.
