Compaction Roller

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 vibration device configured to generate vibrations when driven by a vibration motor;
• 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 their adjoining inside tire of the corresponding pair of tires synchronously and transmits the vibration from the vibration device 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;
• 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 is interposed between the outside and inside tires and supports the corresponding traveling drive shaft through bearing device;
• and
• a second support bracket, which is connected to both of the pair of first support brackets on an unsprung mass side than the first vibration proof device and is interposed between the inside tires of the two pairs of tires and supports the pair of traveling motors,
• wherein the vibration device includes a vibrator case extended between the pair of first support brackets above the tires, and the second support bracket is connected to the vibrator case.
