The present invention concerns a hydraulic system comprising a hydraulic pump () installed on a truck tractor (), a hydraulic pipe () connected to the outlet of the pump () and a connector () positioned at the outlet of the pipe () and designed to be connected to a complementary socket () provided on a trailer () in order to supply a ram () positioned on the trailer, for example for tipping purposes, characterised by the fact that it comprises a circuit selector () designed to connect said socket () selectively either to a ram () or a conduit () supplying a drive assistance circuit and an assistance circuit return conduit () designed to be connected to a tank () positioned on the truck tractor.

System for assisting the driving of a trailer from an open tipping hydraulic circuit

A hydraulic braking valve having an inlet orifice intended to be connected to a pressure supply, an outlet orifice intended to be connected to a braking unit, a leak orifice intended to be connected to a tank, a power distributor adapted so as to connect the inlet orifice to the outlet orifice in a braking configuration, and a leak orifice to the outlet orifice in a rest configuration. The power distributor is driven by two independently driven calibrators.
