According to the axle arrangement of single axle single wheel, double axle double wheel, double axle three wheel and three axle three wheel and so on. With internal combustion engine as the power, mechanical transmission or hydraulic transmission. General front - wheel steering, good mobility, rear - wheel drive. In order to improve the steering and rolling performance, articulated steering structure and all-wheel drive should be adopted.
According to the axle arrangement of single axle single wheel, double axle double wheel, double axle three wheel and three axle three wheel and so on. With internal combustion engine as the power, mechanical transmission or hydraulic transmission. General front - wheel steering, good mobility, rear - wheel drive. In order to improve the steering and rolling performance, articulated steering structure and all-wheel drive should be adopted. The front wheel frame and rack are hinged to reduce road surface irregularities with the fuselage swinging. The rear wheel and the frame are rigidly connected. Adopt hydraulic control, with hydraulic cylinder control steering. The front and rear rollers are equipped with scraping plates to remove the adhesion from the rollers. A water spraying system is also installed to prevent the asphalt mixture from sticking to the roller as the asphalt pavement is compacted. In order to increase the force can also be installed in the roller, such as iron, sand, water to increase the pressure.
As early as in ancient times, people used the hoofs of herds to stomp, knead and compacted the soil to treat the foundation of houses and compacted DAMS and embankments. Before the middle of the 19th century, road engineering in the West was mainly paved with gravel, and compaction was mainly driven by vehicles. It was not until 1858, after the invention of stone rolling machine, which promoted the development of gravel road surface, that compaction work with horse-drawn roller gradually appeared, which was the earliest prototype of the roller. In 1860, steam roller appeared in France, which further promoted and improved the construction technology and quality of gravel road surface and accelerated the progress. At the beginning of the 20th century, it was recognized in the world that the gravel pavement was the best pavement at that time and was promoted worldwide. The concept of compaction was gradually known and the road roller also appeared on various road construction sites. In the middle of the 19th century, the invention of internal combustion engine brought great vitality to the development of compaction equipment. The first steamroller powered by an internal combustion engine was born in the early 20th century. The sheepfoot roller and light wheel roller were produced almost at the same time. The compaction effect of static roller was studied, and it was believed that increasing the weight of the roller could increase the line pressure of the roller, so as to improve the compaction effect. So, in a long period of time, people are committed to the development of large tonnage roller, the largest tire roller once weighed more than 200 tons, but during this period, the change of the roller or mainly reflects the improvement of power and shape.Key words:- Roller 4
