Abstract
This paper deals with the proposal of a practical method for reducing turning motion resistance of the multi-powered wheel vehicle. In the previous paper the same kind of idea as this practical method for improving the turnability of the tracked vehicle was introduced. From that discussion it was found that the proposed method can be effectively applied for actual use of tracked vehicle and it reduced the turning motion reisitance drastically compared with the normal turning motion. Through the experiments, almost the same amount of reduction of turning motion resistance as the tracked vehicle could be observed. This proposed idea of reducing the resistance can be practically applied to commercial off-road vehicle for improving the turnability and the manoeuverability for obstacle negotiation.
