three-point touchdown stable road feeling
The traditional dual-wheel locomotive is considered as a kind of unstable structure because it applies the dual-point touchdown structure, as a result, the locomotive is likely to suffer from sideslips and rollovers during emergency brake, steering and potholes roads, accordingly, the driver is subject to the safety risks.
However, iTank, the intelligent dual-wheel locomotive, which is produced by Doohan, has solved the safety problems in structure, in details, the intelligent and stable supporting system considers the rear wheel as vertex to form the stable three-legged structure with the dual front wheels. In such case, iTank can steadily support on the road and head off the danger regardless of large-angle bending, or the brake in emergency circumstances.
Thanks to the lateral bracing of dual front wheels, iTank will not stand in awe before stairs because the perpendicular throw of dual front wheels reaches up to 183mm, as a result, iTank will not suffer from sideslip and toppling when one wheel is on the stairs and the other wheel is on the road, therefore, the driver can easily cope with the underground garage and road curb. (Show a picture wherein the two wheels are not at the same horizontal level during going through stairs.)
