Outline of Final Research Achievements

The purpose of this study was to develop the new wheel-chair having the function to drive straight by one-hand operation. To perform this purpose, the driving force transmission axis (DFTA) which had transmitted the driving force from the one side of wheel to another side of that was developed. The wheel-chair could drive straight by one-hand operation by the DFTA. The large torque, however, was generated in the DFTA, because the DFTA transmitted the driving force from the one side of wheel to another side by the axis of small diameter. Furthermore, the shear stress in the DFTA generated by this torque would lead to the DFTA break. The shear stress in the DFTA was calculated to examine the axial strength and durability. On the DETA of the wheelchair, the maximum shear stress calculated from the torque in driving was 44.0N・m and this was defined as the standard of the demand specifications as a strength and durability of the DFTA.
