Z Has four walking speed, realize stepless speed in every document, a document for 0~, second gear for 0~, third gear for 0~, four 0~, can guarantee the speed of the rollers in a variety of conditions to make the best paction jobs, and can travel at faster speeds. Vibration bearing life and z in order to improve reliability, this machine uses a unique design: highprecision, forced lubrication of vibrating wheel. Z Vibration system with dualfrequency, dualsite functionality, can be effective paction of different types and thickness of paving material. Z This vibration reduction of a fourlevel structure, making the vibration mode in real time, adverse effects on the crew reduced to a minimum. Coupled with the fortable and bright cabs equipped with air conditioning, creating an ideal working environment for drivers. Z Has a maintenancefree Central hinged device that does not require lubrication. Z This machine is used in diesel engines, hydraulic pumps, motors and axle ponents are internationally famous excellent products, so as to ensure that the roller technology advancement and reliability. Z This machine belongs to super heavy in China39。s standard of vibratory road roller, for highgrade Highway, railway, airport, dam, terminals, a high standard of subgrade engineering paction operations. Compaction of z has a unique ability, max power 56800kg, good paction effect. Z The overall opening of panels, all readily available and maintenance points. Z Centralized, external hydraulic pressure points, making hydraulic systems testing, maintenance more convenient. Z Complete safety protection device, so that operators are fully guaranteed. The second section The overall structure YZ12 type vibration on the roller make use of the wheel of the vibration on the road is pacted, and it has sufficient ability to carry, and reduces through road roller hydraulic control, twowheeled, single steel wheel, selfpropelled structure. This machine vibration wheel parts and vehicle parts including two units, articulated through the Center articulated frame between them together. This machine adopts articulated steering, to improve its performance and mobility. Part including drum vibratory wheel Assembly, front frame Assembly (including scraper) and other parts. Vibration round of the eccentric shaft via elastic coupling and vibration of motor shaft is connected to, supplied by a hydraulic pump vibration in pump high pressure oil to the vibration motor drives eccentric shaft rotate and generate powerful centrifugal force. Frequency and amplitude of vibration can be adjusted by hydraulic system control, to meet the requirements of different operating modes. In addition, the drum also has walking function. By the hydraulic pump high pressure oil pump outputdriven vibration in hydraulic motor rotation of the wheel on the left, thus driving vibration wheel driving. To reduce and even eliminate the adverse effects of vibration on driving car and driver, in the first frame after frame and vibration between wheel and cab and are equipped with a vibration reduction between buffer damping blocks. Driving car parts are rollers and pressure oil supply three system power source. Engine, drive and vibration and steering system, control device, the control room, electrical system, security protection devices are installed in the car. The third section Hydraulic system Road roller hydraulic system in hydraulic system contains three main subsystems, the vibration of hydraulic system, hydraulic system and steering hydraulic system. Three pumps, vibration, steering the triple bination pumping. Walking pump with a gear pump in back tax and penalties as a hydraulic system pump, at the same time, also provide pressure to the brake cylinder oil. II. driving hydraulic syst
