【正文】 by electromagic valve with two oblique angle, so that the machine has four speeds, to meet the needs of different operating conditions. III. vibration of hydraulic system of vibratory hydraulic system is made up of single pump 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 axis piston. By manipulating electromagic valve, you can make the vibration of pumps swashplate with opposite two variable oblique angle, so that different direction and flow of high pressure oil pump output, vibration motor with resulting different steering and speed to vibrations at different frequencies and amplitudes vibration. Four steering steering hydraulic system using opencircuit hydraulic system, the system working pressure 16MPa. By steering pump, hydraulic steering gear, two steering cylinders and tubing and other ponents. Steering pump gear pump. Five hydraulic system of hydraulic control system and accessories 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 system Drive system system is posed of driving hydraulic system, rear axle Assembly. I. driving pump, driving motor driven pump and motor function in the hydraulic system has been introduced. Triple, vibration, steering pump through elastic coupling connection on the flywheel of the connection for driving pumps and motors. Rear axle drive motor connections on the rear axle Assembly gear reducer, input power drive rear axle drive shaft rotation after。 二 ○ 一 三 屆畢業(yè)設(shè)計 外 文 翻 譯 學(xué) 院： 工程機械學(xué)院 專 業(yè)： 機械設(shè)計制造及其自動化 姓 名： 牛鵬 學(xué) 號： 2504090819 指導(dǎo)教師： 陳蝶 完成時間： 年 月 日 Introduction to YZ12 Vibration roller Literature The first section Major technique characteristic Z Vibration, and turned to the three major systems for hydraulic transmission, hydraulic pumps and three systems into one, directly by the engine crankshaft output through elastic couplingdriven pump, and then by the various control ponents control the system of the motor or cylinder, so that all systems running. 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
