ROLLER OF THE ROAD ROLLER Russian patent published in 2022 - IPC E01C19/27 

FIELD: road machinery.

SUBSTANCE: invention relates to road machinery for compaction of road building materials. The roller of the road roller consists of a shell, inside of which there are support rollers that contact the inner surface for the entire width of the shell. The support rollers are connected at both ends by articulated four-link rods. The axes of the left and right rollers are additionally connected by a hydraulic cylinder. The shell is made of an endless caterpillar chain consisting of identical links pivotally connected to each other. The drive roller is equipped with a rotation drive located in the vertical longitudinal plane of shell symmetry and made in the form of a hydraulic drive, including a hydraulic motor, the shaft of which is connected to the drive roller shaft.

EFFECT: increasing the efficiency of compaction of road construction materials and reducing the energy intensity of shell deformation.
