Testing device for rubber track pads

Abstract

This invention provides a testing device for track rubber blocks, comprising a first drive wheel meshing with one end of a track, a load wheel abutting above one end of the track, a rubber block to be tested disposed below one end of a simulation unit, and a second drive wheel meshing with the other end of the track. A road surface simulation component includes a slide rail, a platform, and a damping device. The platform slides above one end of the slide rail, and a road surface simulation plate is disposed above one end of the platform. The load wheel applies pressure, causing the rubber block to be tested to abut against the road surface simulation plate. The first drive wheel and the second drive wheel rotate back and forth in the same direction, driving the simulation unit and the rubber block to be tested to reciprocate above the road surface simulation plate. Simultaneously, the damping device provides damping to the platform and the road surface simulation plate.

The load-bearing roller applies pressure to the simulated part of the track, causing the test rubber block to abut against the top of the road surface simulation plate. The first drive wheel and the second drive wheel rotate back and forth in the same direction, causing the track to reciprocate and drive the simulated part and the test rubber block to rub against the top of the road surface simulation plate. The damping device provides damping to the platform and the road surface simulation plate when the test rubber block rubs against the top of the road surface simulation plate.
