Hydrostatic TRANSMISSION TECHNOLOGY EQUIPMENT

摘要

The invention relates to a hydrostatic transmission technology machines, mainly to the travel drive and all-wheel drive technology process equipment machines. Object of the utility model is a simplification of the construction and expansion of the functionality of hydrostatic transmission of the machine tool. The hydrostatic transmission of the machine tool comprises a steering pump spindle equipment drive pressure line which is connected through a divider - flow adder with the pressure line hydraulic drive axles of the machine tool and further provided with a pump drive process equipment constant performance of steering servo unit control valves hydraulic cylinders drive the steering mechanism control mechanism cylinders drive mechanism swing control of the machine tool. In direct the course of the process equipment machines pump is connected with the pressure line of the pump spindle drive equipment. The proposed solution provides a hydrostatic drive of the executive bodies of the process equipment and machine turning mechanisms. Using a pump to the actuator bodies executive processing equipment and rotating mechanism and switching it on the drive spindle of the machine transmission equipment simplifies and reduces the total amount of actuator stroke pumps and processing equipment, while maintaining the required range of variation of the machine speed and efficiency of its operation in the process mode. 2 SP f-ly, ZP 2 f-ly, 5 Fig.
