ABSTRACT:
A road roller comprises a frame and a pair of drums, at least one of which is a guide drum, on which the frame is pivotally supported. A steering mechanism is attached to the guide drum for steering the road roller. The supporting mechanism for the guide drum includes a vertical pivot shaft coupled to the guide drum, a vertical anti-friction bearing on the pivot shaft for permitting the guide drum to pivot horizontally relative to the frame, and a flexible support coupled between the bearing and the frame for permitting limited lateral twisting of the guide drum relative to the frame. The flexible support comprises a pair of longitudinally spaced rubber mounts for absorbing longitudinal shocks but for inhibiting longitudinal twisting of the drum relative to the frame.
