Abstract

The invention can be used in excavators, cranes, manipulators, forklifts, bulldozers, multiple-engine machines or cyclical mechanisms with hydraulic cylinders and hydraulic motors. The aim of the invention is to create a hydraulic drive that conserves energy and is more economical by reducing the fuel or electrical power expended in combined operations and is also more reliable, while simultaneously reducing heat loss through volume adjustment and energy recuperation. The invention achieves this aim as follows: the hydraulic drive contains a pump unit, hydraulic cylinders, hydraulic motors, supply and cooling unit, distributor hydrojets and feed tank. The pump unit contains at least two paired regulator pumps, each of which is made in the form of two two-way reversible hydraulic units of different and variable working volumes, the control units thereof being kinematically interconnected. The chambers of the two-way reversible hydraulic units with larger working volume are linked through a closed loop with the chambers of the hydraulic cylinders and hydraulic motors. One of the chambers of the two-way reversible hydraulic unit with smaller working volume is linked through the distributor hydrojet with the piston chamber of the hydraulic cylinder or with the tank, while the other chamber of the two-way reversible hydraulic unit with smaller working volume is linked with the tank. The ratio of diameters of pistons and rods in the hydraulic cylinder corresponds to the ratio of larger and smaller working volumes in the two-way reversible hydraulic units.

In this case, it is conveniently turned on and switched on to the hydraulic mode by unloading the prime mover. This energy can be used, for example, due to the combination of the lowering of the building with the accelerated access to the water, which is possible to use. The most efficient way to recover energy is when you combine energy-efficient operations with good ones.
