Because of construction machinery, mostly walking equipment, improve the load capacity is limited by weight and installation space. For this reason, the system requirements constituent elements with high power weight ratio (Strength-to-Weight), namely, large output and light weight, small size under the premise to meet the job requirements. Hydraulic system, in particular the implementation of components (cylinders and motors) weight loss, weight loss and construction machinery load capacity and improve efficiency plays an important role. The cylinder had a high percentage of the hydraulic motor repair in the total weight of the hydraulic cylinders, especially with the increase in travel, the hydraulic motor repair, cylinder cylinder the total weight of the total percentage will increase, sometimes as high as 75%, hydraulic motors, so the cylinder weight loss is mainly cylinder weight loss. Such as the use of carbon fiber reinforced plastics (CFRP) the above-mentioned hollow cylinder piston cylinder of material, because of its high strength and toughness, can withstand up to 70 MPa working pressure. Because the cylinder piston is hollow, so the total weight of the cylinder with the specifications than steel cylinders alleviate 65%. Such cylinders will be used to improve efficiency wheeled excavators are 20% higher than when using a steel cylinder. Hydraulic CVT works according to the hydrostatic principle. It consists of two piston composed, as a pump, and the other as a hydraulic motor. Two pumps are coaxially mounted on the center divider, the central distributor is connected with the transmission housing. To form a closed hydraulic fluid system housing. The hydraulic fluid from the pump to the hydraulic motor, or vice versa. Oil pump driven by the electric motor, hydraulic motor parts, hydraulic motor torque to the output shaft of the transmission. Changes in the volume of the pump can change its speed. Large displacement pump is high speed, low speed hydraulic motor and vice versa |.
