Abstract

The goal of researching is finding alternative constructions of hydraulic actuator of the carcass lifting device, which are working without using internal combustion engine energy and, consequently, guarantee energy saving and economical effect of technological car using. In the article it was offered the construction of original hydraulic actuator of the carcass lifting device. The feature of such hydraulic system is using hydraulic accumulator of high pressure, plunger pumps, control systems, herewith gear pump and its drive from car engine, which are specific for serial lifting mechanism, in the offered scheme are not present. As a source of energy, which is needed to lift the carcass, was offered not to use the internal combustion engine, but hydraulic accumulator with recharging from chattering of the car sprung mass. The feature of this hydrosystem is the use of a high pressure accumulator, plunger pumps, control system, with the gear pump and its drive from the engine of the car, typical for the serial lift mechanism, in the proposed scheme are absent. As a source of energy necessary for lifting the body, it is proposed not to use an internal combustion engine, as in serial hydraulic drives, and a hydraulic accumulator with the energy of the working fluid accumulated from the oscillations of the submerged car's masses. Was counted the economy, which can be earned by the reducing of the fuel uses, during realization of unloading operations of one car per year.
