Abstract
The introduction and functional expansion of hydraulic drives expands the use of hydraulic systems as a power take-off, providing the possibility of independent drive of different consumers in a wide range of loads. The flagships of foreign agricultural, road, industrial engineering equip their products with hydraulic systems, the power of which significantly exceeds 70 kW and this figure continues to grow. Due to the fact that the developers of mobile energy are in a rigid framework for size, fuel and other indicators, the creation of such equipment is through the introduction of universal hydraulic systems. Universalization of hydraulic systems to ensure the work of external consumers is one of the most important tasks in the development of hydraulic systems. But, despite more than age development and improvement of the hydraulic drive, scientific researches for the purpose of creation of universal and more economic models are actively conducted in different countries of the world. The big disadvantage of these designs is the inability to change the speed of the shaft of the hydraulic motor drive equipment, because this parameter depends on the wear of components and parts of the hydraulic drive, oil temperature. An important indicator of modern hydraulic drives is the introduction of adjustable pumps, which significantly expand the potential of the hydraulic drive by improving the technical and economic performance. In this case, the drive of all equipment is provided by one pump. Such “centralized” systems operate from a single energy source and air conditioners. As a result the possibility of return rotation of the hydraulic motor, its braking, smooth change of frequency of rotation of a drive of the equipment of agricultural machines is provided. But, despite more than age development and improvement of the hydraulic drive, researches for the purpose of creation of universal and more economic models are actively conducted in different countries of the world.
