Zoomlion is committed to promoting the full hydraulic pressure in the field of compaction machinery. Its fist-product full hydraulic single-drive single-roller series roller has undergone two years of market test, showing a vigorous market vitality. At the beginning of the Year of the Dog, along with the implementation of the brand strategy of the road machine, a new generation of full hydraulic single-roller roller series YZD18, YZD20A came into being.
On the basis of inheriting the advantages of the previous generation of roller compactors of Zhonglian, the series of road rollers have the following outstanding features after many major technical improvements and process upgrades:
First, the machine performance:
The vibrating wheel adopts Zhonglian's patented technology, double-axis four-bearing structure and good rigidity. It adopts German FAG heavy-duty bearing, long design life and multi-channel multi-point lubrication technology to ensure good and sufficient lubrication of bearings and improve bearing life. .
The cab is patented without sloshing, greatly improving driver comfort and safety. The highly humanized design of the driving space has completely changed the vulgar image of construction machinery, especially the road roller, and it is exquisite and exquisite in the rough and powerful, showing the noble temperament and extraordinary affinity.
By optimizing the configuration, the stability and reliability of the vibration system are greatly improved. The field test data proves that the new generation of full hydraulic single-roller roller series YZD18 and YZD20A can fully meet the basic engineering construction including high-speed railway.
Second, the power system:
The Dongfeng Cummins 6BTA5.9 supercharged construction machinery diesel engine is used, and the famous brand radiators produced by German technology are used at the same time. The reliability of the engine is improved and the noise of the whole machine is reduced. The drive axle of the fully hydraulic single-drive single drum compactor developed jointly with the famous domestic joint venture manufacturers ensures high stability and reliability of the whole machine performance.
Third, the hydraulic system
The vibration system adopts the piston pump and plunger motor closed system of Sauer United States. The reliability and stability of the vibration system are qualitatively improved compared to the open gear pump and motor system. The vibration system can be double-frequency and double-width change, and the compaction effect and compaction efficiency are significantly improved. The hydraulic travel drive adopts the piston pump and plunger motor closed system of Sau's in the United States, which can realize stepless speed change, improve the running performance and compaction performance of the roller, and there is no shifting impact during the operation, and no ripple effect on the road surface. And destruction effects. Improve the walking drive torque, the overall climbing ability of the machine is improved. The application of the oil suction coarse filter and the oil pressure fine filter system greatly improves the anti-fouling ability of the hydraulic system and effectively improves the service life of the hydraulic system.
Fourth, the structure of the production
All the cabs, engine covers and consoles have been moulded, which not only improves the production level of the products, but also improves the appearance quality of the products. The cab uses blister interiors to reach the mid-level interior of the car, which is also the first in the domestic compaction industry. Re-optimizing the structural parts, improving the painting process, improving the surface quality and paint quality of the whole machine, making it more in line with the overall aesthetic of the whole machine.
