Title:

TRACTION CONTROLLER FOR CRAWLER VEHICLES

Document Type and Number:

WIPO Patent Application WO/1993/021053

Kind Code:

A1

Abstract:

This invention relates to the controlling of the travel of a crawler vehicle and aims at resolving the issue of making a crawler vehicle travel on an ungraded land with the crawlers effectively gripping the road surface. According to the present invention, the loads imparted to crawlers (12FL, 12FR, 12RL, 12RR) are detected, and, on the basis of the results of this detection, the sum of the loads on a pair of crawlers (12FL, 12RR) at the front left and rear right sides of a vehicle and the sum of the loads on a pair of crawlers (12FR, 12RL) at the front right and rear left sides thereof are computed. When a difference between the sums thus computed has become not lower than a predetermined level, it means that diagonal stack occurs. In such a case, the pivots (14) of a pair of crawlers having smaller loads are driven in a direction in which the loads imparted to the same crawlers increase, so that the floated pair of crawlers contact the road surface, these crawlers thus capable of providing an effective driving force. This invention is used mainly when a natural disaster rescue crawler vehicle travels on an outdoor ungraded land.
