【正文】 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 system with a dualmotor pumps consisting of parallel closedcircuit. System operating pressures up to 40MPa. Driving pump for the variable displacement piston pump, piston driving motor for variable before, it constitutes the best bination and plaary reducer. Drive motor is also variable piston after, enter the end connected to the gearbox and rear axle assemblies. Pump to control the angle of oblique to change high pressure oil flow and direction, so as to change the direction of travel of the machine and speed。 vibration wheeldrive motor with plaary gear reducer constitute one connection in plum of vibratory wheel on plate Asse mbly, powered by the motor to the plum blossom plate Assembly, Phillipsdriven plate Assembly vibration wheel rotation. In order to reduce and even eliminate the adverse effects of vibration on driving cars and drivers, plum blossom plate Assembly and connection of vibration between wheel is equipped with imported high quality damping blocks. II. rear axle Assembly rear axle Assembly by reducer, wet multiple brakes, Central plaary reducer transmission, drive axle, wheel, wheels and other ponents. III. low pressure wide cross section of OTR tire tire assembly tire. Specifications for per cent, inflation pressure The fourth section Vibration wheel assembly Vibrating wheel assembly of vibratory wheel assembly eccentric of vibratory wheel axis, amplitude modulation device, vibration, vibrating wheel vibration of driven motor, bearings, vibration motors, mobile support, housings, plum flower plate, left and right connection brackets and so on. I. vibratory wheel of vibratory wheel diameter of 1600mm, width 2170mm. Vibrating wheel plate rolling body butt into its round smooth, uniform wall thickness, can ensure the vibration paction effect uniform, preferably in the pavement of paction effect and can be used as static pacted solid. Body cavity loaded vibratory wheel bearings, eccentric axis, amplitude modulation device, this sealed Chamber containing Mobil629 Mobil gear oil. II. eccentric shaft eccentric shaft vibration generators, machine vibration is generated by vibration motor drives eccentric shaft high speed rotation. One end of the eccentric shaft and the vibration motor connected, change the Rotary to can change the amplitude of the vibration motor. III. amplitude modulation device amplitude modulation device mounted on the eccentric shaft, set role of amplitude. Location of the device by changing the amplitude modulation and amplitude modulation block, achieve the purpose of adjusting the amplitude. Amplitude modulation device is a sealed cylindrical welded structures. IV. damping blocks in order to mitigate the effects of vibration on the frame, the vibration between wheel and front frame with rubb
