Introduction

The modern level of development of construction and road engineering is characterized by the wide use of a volumetric hydraulic drive. The wide use of the hydraulic drive is due to a number of advantages in comparison with other types of drive. The main advantages include: a small specific gravity, the implementation of large gear ratios, stepless control of the speeds of actuators, reliable protection from overloads, ease of control and ease of its automation.

More than 80% of all construction and road machines have a hydraulic drive. It is used to drive working equipment, wheel and track propulsion, remote supports, steering, etc.

The main tasks in the design are to calculate the main parameters of the volumetric hydraulic drive and, on its basis, select typical, normalized and standard equipment.
