SYSTEM FOR ASSISTING THE DRIVING OF A TRAILER FROM AN OPEN TIPPING HYDRAULIC CIRCUIT
The present invention concerns a hydraulic system comprising a hydraulic pump (130) installed on a truck tractor (10), a hydraulic pipe (160) connected to the outlet of the pump (130) and a connector (170) positioned at the outlet of the pipe (160) and designed to be connected to a complementary socket (180) provided on a trailer (20) in order to supply a ram (110) positioned on the trailer, for example for tipping purposes, characterised by the fact that it comprises a circuit selector (210) designed to connect said socket (180) selectively either to a ram (110) or a conduit (220) supplying a drive assistance circuit and an assistance circuit return conduit (250) designed to be connected to a tank (120) positioned on the truck tractor.
Power split transmission and method for operating such power split transmission
A power-split transmission which is designed to be operated with either first or second deceleration logics. The second deceleration logic has a higher deceleration dynamic than the first deceleration logic, and is designed to disengage an engaged range clutch immediately so as to reduce the transmission ratio by way of a hydrostatic unit with a maximum dynamic. A method of operating the transmission includes: monitoring various vehicle parameters while the vehicle is operated with the first deceleration logic; detecting that at least one set limit value has been exceeded while the vehicle operated with the first deceleration logic; activating the second deceleration logic, to immediately disengage an engaged range clutch; reducing a transmission ratio to a maximum using the hydrostatic unit, the hydrostatic unit being displaced with a maximum dynamic; and engaging the range clutch and activating the first deceleration logic.
