RBP File No. 5605-003 A soil compactor for use in compacting soil or other materials, has full isolation of the operator's station from both front drum vibration and rear road shocks. The compactor contains a front frame articulately joined to a rear frame. The compactor also contains a subframe which supports an operator's station, motive power, and dual fuel/hydraulic oil tank. The subframe is mounted on rubber shocks to the rear frame. The compactor is constructed with a rollover protection structure (ROPS) bolted to the subframe and mounted on isolation mounts to the rear frame. At the rear of the vehicle, a pair of isolation mounts are disposed between the vehicle's dual tank and the rear frame. This structure serves to isolate the operator's station from the drum vibration transmitted through the front frame as well as from the road shock and vibrations transmitted from the rear tires to the rear frame. The soil compactor contains a drum drive consisting of a hydraulic drum motor with splined shaft which is rotatable with the drum hub and a spindle. The spindle is located between the hub and the motor and surrounds the shaft of the motor. Cylindrical roller bearings are placed between the spindle and the hub to permit the hub and motor shaft to rotate with respect to the spindle, and to withstand vibration transmitted by the drums.
