Compaction Roller

摘要

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.

主权项

1. A compaction roller of a type that a front wheel or a rear wheel is including four tires coaxially arranged side by side in a vehicle width direction and four tires are arranged in two pairs in which one pair is arranged in a right side of the compaction roller and the other pair is arranged in a left side of the compaction roller, the compaction roller comprising:
a pair of traveling drive shafts, each of which is arranged corresponding to one of the two pairs of tires and drives an outside tire and its adjoining inside tire of the corresponding pair of tires synchronously and transmits a vibration from a vibration device, which generates the vibration when driven by a vibration motor, to the outside and inside tires; a pair of traveling motors, each of which is arranged corresponding to one of the pair of traveling drive shafts and drives the corresponding traveling drive shaft; and a pair of first support brackets, each of which is arranged corresponding to one of the pair of traveling drive shaft and is mounted through a first vibration proof device on a vehicle body and interposed between the outside and inside tires and supports the corresponding traveling drive shaft through a bearing device, wherein the vibration device includes a pair of vibration sources each of which is disposed within the corresponding traveling drive shaft.
