SYSTEM OF AUTOMATIC REGULATION OF STIFFNESS OF ROAD ROLLER ROLL Russian patent published in 2014 - IPC E01C19/27 

FIELD: construction.

SUBSTANCE: system of automatic regulation of stiffness of a road roller roll comprises: an upper band, a lower band, a spring, a rope clamp, a metal rope, a tension pulley, a drive motor, a reducer. The band is made as split. Parts of the band are connected with a spring, inside the spring from the rope clamp a metal rope is pulled, one end of which is fixed to ends of the band part, and the second end is fixed to the tension pulley located on the frame or axis of the roll.

EFFECT: increased efficiency of compaction of road construction materials, simplified system of regulation of roll stiffness, increased efficiency of works.
