| 内容記述 | In this paper, a practical method of reducing the resistant force acting on the crawlers of the tracked vehicle under steering motion is discussed. It is well known that the increase of the contact area, of the crawlers to soil can improve much tlre trafficability especially on soft loose ground, maintaining a better floatation of the vehicle in straight travelling.. The enlargement of the contact area of the forcedly braked inner track in steering motion produces resistance against the powered outer track. Therefore the contact area of the inner track should be as small as possible, that is, just enough to support the half of the vehicle weight at one pivoting point in steering motion of the vehicle. The enlargement of the contact area sometimes leads to the increase of running resistance and wide contact area produces the resistant force against the powered outer track when the inner track is forcedly braked for steering. It can be therefore concluded from this fact that the contact area of the crawlers to soil should be desirably adjusted or controlled, depending on the vehicle's motion behavior for steering and straight travelling. The contact area of the crawlers should be more in straight travelling, and less in steering. There are two ways of changing the contact area : by shortening the width of grousers, or by varying the contact length of the crawlers. To change the contact length of the crawlers seems to be comparatively easier than to change the width of grousers. Some of the practical mechanisms of controlling the change of the contact area and reducing the resistant force occured in steering motion were proposed. In addition to this, the total distance required for the combine to complete the harvesting operation for any given area of the field was estimated. Based upon this analysis the percentage of the distance spent for straight travelling and for turning due to steering operation was also calculated. The durability of the combine crawlers was evaluated from the point of estimated total distance which the combine can travel before it can be scrapped. The possibility of applying this method of controlling the contact length of crawlers to the actual tracked vehicle is based on the considerations of (1) less distance required for steered turning compared to the distance required for straight travelling, and (2) excess cost of mounting such a control device. Further theoretical investigation will be reported in the following work. | |||||||||
