摘要
The invention relates to road construction vehicles and is designed to seal the pavements, bases and primers. The object of the utility model is a reduction of energy compaction road-building materials, and improving the efficiency of vibrating rollers by lowering the number of required passes. Oscillating roller road roller rotated by a motor 1 which is connected through a reduction gear 2 with a rim 3 which surface is coated with a layer of rubber 4. Inside the drum are arranged transverse ribs 5, which has two oppositely unbalanced shaft 6 connected to the drive shaft 8 via the gear train 7. unbalance shafts consist of fixed cams 10, integral with them, and the movable cams 11. since the eccentric weight shafts 6 are offset by 180 °, on the torsional vibrations transmitted to the drum (oscillation yatsii). When changing the direction of rotation of the unbalanced shafts 8 varies the eccentricity r mass, which leads to a change in torque and, consequently, to changes in the torsional oscillation exciter. Thus, two values are set torsional vibration of the oscillatory roller: high - when compacting thick layers or low - when compacting thin layers of bituminous mixture. 5 yl.
