Increasing the efficiency of the hydraulic drive of the running equipment of modern excavators

Abstract

The article deals with the problem of efficiency of running equipment of construction machines. The development of construction technology and earthmoving works raises the question of improving the control system of excavator travel mechanism. Application of modern regulation system in the design of road-building machine will allow the hydraulic system of excavator running equipment to meet modern design efficiency indicators. The most promising is the method of volumetric regulation of hydraulic drive, which allows to provide working or transportation speed of excavator. The article considers the features of the volumetric method, designed to change the speed of rotation of the output shaft of the hydraulic motor, by regulating its working volume, with the help of elements involved in the operation of the running equipment of the excavator.
