(2), after entering road surface, level land 113, front-wheel 23 and trailing wheel 14 be ground connection and supporting car body and front and rear wheel 23,14 V-

type endress belt

23,15 all are earth-free state simultaneously.See Fig. 1,8,9.

(3), when running into protruding road surface or step road surface 111, the V-type endress belt 26 of front-wheel 23 can first contact this road surface 111 and be attached to the crowning on this road surface with its groove 19 and projection 16, or the V-type endress belt 15 of trailing wheel 14 also can contact subsequently this road surface and be attached to the crowning on this road surface or the road surface at angle is arranged with its groove 19 and projection 16, thereby makes car possess progressive propulsive force and can continue to move ahead (being that car just can not be obstructed or can not halt); Simultaneously, due to after V-

type endress belt

26,15 also can contact this road surface subsequently, relatively reduced widely front-wheel and trailing wheel and crossed the difficulty on such obstacle road surface and make car cross relatively easily such road surface and advance forward.

(4), when running into the road surface of chiltern or muddy or ice and snow formula, front-wheel 23 and V-type endress belt 26 thereof, trailing wheel 14 and V-type endress belt 15 thereof be ground connection simultaneously, although front-wheel 23 and trailing wheel 14 are because being absorbed in such road surface or " skidding " loses the propulsive force that continues to move ahead, but

such endress belt

26,15 is supported car body and possesses the propulsive force of advancing forward because increasing widely its ground contact area, thereby reach the purpose (but, except such too soft road surface) that vehicle can move on.

When Vehicular turn,

(1), the power of steering wheel rotation 6 is axle 105, universal-joint 104, slip joint 103, lower shaft 102, miniature gears 109 on bearing circle, and transmission and the axis around rotation central axis that makes fan tooth 101 make horizontal rotate, promote simultaneously steering box Connection Block 53 and do the synchronous axis rotation around rotation central axis; Power is through forerunner's connection bracket 3 and forerunner---and turn to girder 28, forerunner's drive assembly 1, auxiliary connecting rod 25, forerunner's main tie 30, left and right
