Abstract
The utility model provides an airbag type road surface acceleration and loading test device, which belongs to the test device field and comprises a machine body. A rolling compaction wheel, an airbag and a spoke assembly are arranged in the machine body. The spoke assembly comprises a spoke, a swing frame and a connected shaft. The spoke is driven by a motor through a V-shaped belt and a reducer so that the swing frame drives the rolling compaction wheel to rotate around the connected shaft. The utility model is characterized in that the airbag pressurizes the rolling compaction wheel through the swing frame, the rolling compaction wheel is driven by the spoke assembly to rotate around the connected shaft and roll a road surface so that the rolling compaction situation of wheels on the road surface can reappear when a vehicle runs and the accuracy of test conclusion and test efficiency are improved.
