Good ride comfort is of vital importance to the health and safety of machine operators. Low vibration is a key factor considered when selecting a machine and a rubber track. Some vibration is caused by the vertical movement of track rollers when dropping into the gaps between each core metal protrusion.
Bridgestone has reduced the vertical movement of the track rollers by adopting an advanced tapered protrusion technology. The tapered shape of the running surface of the protrusion optimizes the roller path against the natural rotation of the core metal under vertical load. This results in good ride comfort without the need of additional material. Avoiding the use of additional material is in line with Bridgestone's environmental policy.
Data obtained by FEM analysis and field testing clearly shows a reduction in vibration using tapered core metals. This brings greater ride comfort to the operator.
