Abstract: A compaction roller comprises a vibration device for generating vibrations when driven by a vibration motor; a pair of right and left traveling drive shafts, while traveling driving outside tires and their adjoining inside tires synchronously, for transmitting the vibrations of the vibration device to the outside tires and inside tires; a pair of right and left traveling motors respectively for driving their associated traveling drive shafts; and, a pair of right and left first support brackets mounted through a first vibration proof device 6 on a vehicle body and interposed between the outside tires and inside tires for supporting the traveling drive shafts through bearings, wherein the vibration device includes a vibration source disposed within the traveling drive shafts. According to the compaction roller, a side overhang can be eliminated or reduced, and enabling prevention of the lowered vibration compacting function of the tires.

Abstract: The compaction vehicle having a speed adjustment member, a displacement detector, and a drive source controller further includes a calculation device between the displacement detector and the drive source controller, receiving the displacement S, and outputting a signal I calculated to the controller; a running speed setting switch for the operator operating ON at a desired running speed; a control signal memory device provided inside the calculation device and memorizing a signal I1 to the controller. In a normal operation, the calculation device outputs the signal I to the controller so that a running speed increases or decreases according to the displacement S, and when the switch is operated to ON, the calculation device maintains the ON state, and the displacement S is not less than a predetermined value, the calculation device outputs the signal I1 memorized in the memory device so as that the vehicle will run at a constant speed.
