This paper describes the dynamic behavior of a driving truck with independently rotating wheels. Computer simulations, considering the independently rotating wheel, no-spin differential gear and traction torque, were executed. Then, the truck was tested in field. The findings from simulations and the field test are as follows : (1) No-spin differential gear is apt to cause one-wheel drive at a curve and track irregularities. One-wheel drive has a disadvantage in terms of adhesion. (2) When the right and left wheels alternately repeat one-wheel drive, the lateral displacement of the wheelset becomes large. (3) When the traction torque is given to the one side wheel only, the dynamic behavior of the wheelset differs depending on how quick the torque increases. That is, when the traction torque is given in an instant, the wheelset moves laterally in an instant, but when the traction torque is given gradually, the wheelset does not move laterally in an instant.
