Briefly introduce the purpose and classification of a road milling bit, and analyze the road milling block system used in the traveling system of the representative model of road milling bit at home and abroad. Summarizing the advantages and disadvantages of the four transmission routes of the hydraulic-mechanical hybrid transmission, enumerating the representative models, it is concluded that the hydraulic-mechanical hybrid transmission has certain defects in terms of power performance, operating efficiency, reliability, and safety performance. Through the comprehensive analysis of the full hydraulic transmission mode, it is pointed out that the full hydraulic transmission has unparalleled advantages in terms of power performance, safety performance, reliability, and the convenience of the layout of the whole machine. It is the future of road milling machine technology development.

Classification of road milling machines
According to the different working widths of the milling rotor, road milling bits can be divided into three types: small, medium, and large. Under normal circumstances, the milling width of a small road milling machine is 300-800 mm, which is mainly suitable for road maintenance projects with a construction area of less than 100 m 2; the milling width of a medium-sized road milling bit is 1 000-2 000 mm; for large roads, The milling width of the milling machine is more than 2 000 mm. Generally, when working with other machines, it can form a complete set of equipment for road regeneration and repair. The position of the milling rotor in the milling machine is the rear suspension type, the middle suspension type, and the same as the rear axle.
There are three types of shafts. The rear suspension type means that the milling rotor is suspended at the rear of the rear axle. The middle suspension type means that the milling rotor is placed between the front and rear axles.
According to the different milling forms, road milling bits can be divided into two types: hot milling and cold milling. The hot-milling milling machine uses far-infrared rays to heat the road surface and then performs milling operations. Due to the addition of a heating device, the structure of the whole machine is more complicated. Generally, it is only suitable for the regeneration of asphalt pavement.
Comparison of the transmission mode of road milling machine
The road milling block system mainly includes two modes: hydraulic-mechanical hybrid transmission and full hydraulic transmission. In foreign countries, all small and medium-sized road milling bits produced by Wirtgen with a milling width of 500 mm and above adopt full hydraulic transmission, while most of the domestic small and medium-sized road milling bits adopt hydraulic and mechanical hybrid transmission.
RUIAN FLY MACHINE PARTS CO., LTD has developed a variety of road milling bits and conducted a lot of tests before leaving the factory to ensure quality. These road milling bits not only have a large exhaust capacity but also have strong endurance. If you are in the road milling bit business, you can consider using our cost-effective products.
