The first section Major technique characteristicVibration, and turned to the three major systems for hydraulic transmission, hydraulic pumps andthree systems into one, directly by the engine crankshaft output through elastic coupling-drivenpump, and then by the various control components control the system of the motor or cylinder, sothat all systems running.Vibration system with dual-frequency, dual-site functionality, can be effective compaction ofdifferent types and thickness of paving material.This vibration reduction of a four-level structure, making the vibration mode in real time, adverseeffects on the crew reduced to a minimum. Coupled with the comfortable and bright cabs equippedwith air conditioning, creating an ideal working environment for drivers.Has a maintenance-free Central hinged device that does not require lubrication.This machine is used in diesel engines, hydraulic pumps, motors and axle components areinternationally famous excellent products, so as to ensure that the roller technology advancement andreliability.This machine belongs to super heavy in China's standard of vibratory road roller, for high-gradeHighway, railway, airport, dam, terminals, a high standard of subgrade engineering compactionoperations. 59716
Compaction of z has a unique ability, max power 56800kg, good compaction effect.The overall opening of panels, all readily available and maintenance points.Centralized, external hydraulic pressure points, making hydraulic systems testing, maintenance moreconvenient.Complete safety protection device, so that operators are fully guaranteed.The second section The overall structureYZ12 type vibration on the roller make use of the wheel of the vibration on the road is compacted,and it has sufficient ability to carry, and reduces through water.YZ12-vibration road roller hydrauliccontrol, two-wheeled, single steel wheel, self-propelled structure.This machine vibration wheel parts and vehicle parts including two units, articulated through theCenter articulated frame between them together. This machine adopts articulated steering, to improveits 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 andvibration of motor shaft is connected to, supplied by a hydraulic pump vibration in pump highpressure oil to the vibration motor drives eccentric shaft rotate and generate powerful centrifugalforce. Frequency and amplitude of vibration can be adjusted by hydraulic system control, to meet therequirements of different operating modes. In addition, the drum also has walking function. By thehydraulic pump high pressure oil pump output-driven vibration in hydraulic motor rotation of thewheel 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 firstframe after frame and vibration between wheel and cab and are equipped with a vibration reductionbetween 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, securityprotection devices are installed in the car.The third section Hydraulic systemRoad roller hydraulic system in hydraulic system contains three main subsystems, the vibration ofhydraulic system, hydraulic system and steering hydraulic system. Three pumps, vibration, steeringthe triple combination pumping. Walking pump with a gear pump in back tax and penalties as ahydraulic system pump, at the same time, also provide pressure to the brake cylinder oil. II. drivinghydraulic system with a dual-motor pumps consisting of parallel closed-circuit.System operating pressures up to 40MPa. Driving pump for the variable displacement piston pump,piston driving motor for variable before, it constitutes the best combination and planetary reducer.Drive motor is also variable piston after, enter the end connected to the gearbox and rear axleassemblies. Pump to control the angle of oblique to change high pressure oil flow and direction, so asto change the direction of travel of the machine and speed; variable piston by electromagnetic valvewith two oblique angle, so that the machine has four speeds, to meet the needs of different operatingconditions. III. vibration of hydraulic system of vibratory hydraulic system is made up of singlepump Dan Mada closed hydraulic circuit, maximum working pressure of the system is 38MPa.Vibration pump for variable inclined plate piston pump, vibration motor for quantitative inclined axispiston.By manipulating electromagnetic valve, you can make the vibration of pumps swashplate withopposite two variable oblique angle, so that different direction and flow of high pressure oil pumpoutput, vibration motor with resulting different steering and speed to vibrations at differentfrequencies and amplitudes vibration.Four steering steering hydraulic system using open-circuit hydraulic system, the system workingpressure 16MPa. By steering pump, hydraulic steering gear, two steering cylinders and tubing andother components. Steering pump gear pump. Five hydraulic system of hydraulic control system andaccessories also include integrated control valve block, collection block, and tanks, filters, coolers,accessories. Hydraulic brake oil of systems at the same time for the braking system provides.The fourth section Drive system systemDrive system system is composed of driving hydraulic system, rear axle Assembly. I. drivingpump, driving motor driven pump and motor function in the hydraulic system has been introduced.Triple, vibration, steering pump through elastic coupling connection on the fly-wheel of theengine.Hose connection for driving pumps and motors. Rear axle drive motor connections on the rearaxle Assembly gear reducer, input power drive rear axle drive shaft rotation after; vibrationwheel-drive motor with planetary gear reducer constitute one connection in plum of vibratory wheelon plate Assembly, powered by the motor to the plum blossom plate Assembly, Phillips-driven plateAssembly vibration wheel rotation. In order to reduce and even eliminate the adverse effects ofvibration on driving cars and drivers, plum blossom plate Assembly and connection of vibrationbetween wheel is equipped with imported high quality damping blocks. II. rear axle Assembly rearaxle Assembly by reducer, wet multiple brakes, Central planetary reducer transmission, drive axle,wheel, wheels and other components. III. low pressure wide cross section of OTR tire tire assemblytire. Specifications for 23.1 per cent, inflation pressure 1.1kgf/cm2.The fifth section Vibration wheel assemblyVibrating 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 andso on.I. vibratory wheel of vibratory wheel diameter of 1600mm, width 2170mm. Vibrating wheel platerolling body butt into its round smooth, uniform wall thickness, can ensure the vibration compactioneffect uniform, preferably in the pavement of compaction effect and can be used as static compactedsolid. Body cavity loaded vibratory wheel bearings, eccentric axis, amplitude modulation device, thissealed Chamber containing Mobil-629 Mobil gear oil.II. eccentric shaft eccentric shaft vibration generators, machine vibration is generated by vibrationmotor drives eccentric shaft high speed rotation. One end of the eccentric shaft and the vibrationmotor 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, setrole of amplitude.
