(2), enter road surface, level land 113 after, front-wheel 23 and trailing wheel 14 be ground connection and supporting car body and the V- type endress belt 23,15 of front and rear wheel 23,14 all is earth-free state simultaneously.See Fig. 1,8,9.
(3), when running into protruding road surface or step road surface 111, this road surface 111 of the V-type endress belt 26 of front-wheel 23 contact earlier also is attached to this ground-surface crowning with its groove 19 and projection 16, or the V-type endress belt 15 of trailing wheel 14 also can contact this road surface subsequently and be attached to this ground-surface crowning 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, because after V- type endress belt 26,15 also can contact this road surface subsequently, relatively reduced front-wheel and trailing wheel widely and crossed such obstacle ground-surface difficulty and make car more easily cross such road surface and advance forward.
(4), when running into the road surface of chiltern or mire 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, though front-wheel 23 and trailing wheel 14 are because of being absorbed in such road surface or " skidding " loses the propulsive force that continues to move ahead, but such endress belt 26,15 is because of increasing its ground contact area widely car body is supported and possessing the propulsive force of advancing forward, thereby reach the purpose that vehicle can move on (but, too soft such road surface except).
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 connects support 3 and forerunner through the forerunner---and turn to girder 28, forerunner's drive assembly 1, auxiliary connecting rod 25, forerunner's main tie 30, left and right front wheel spindle 31,47, forerunner's bumper connecting assembly 7 (comprising bumper 32), front-wheel 23 (being the near front wheel 46 and off front wheel 29) and preceding V-type endress belt 26 thereof, and make them make synchronous rotary swing.Thereby realize to the left or to the right vehicle the near front wheel 46 and the turning to of off front wheel 29.See Fig. 4,5,6,7.
(2), the single freewheel 1 (or single freewheel 3 86) of a left side (or right) side can form different rotating speeds with the single freewheel 3 86 (or single freewheel 1) of right (or left side) side, all the time have the single freewheel of a side to be automatically converted to pulley-type rotation (unpowered state when being equivalent to neutral gear), thereby its corresponding homonymy front-wheel 23 and trailing wheel 14 are realized differential functions.This is the explanation under Fig. 4 situation.For example, when the vehicle left-handed turning to the time, the rotating speed of the single freewheel 3 86 on the revolution ratio right side of the single freewheel 1 in left side is slow, thereby realizes the front-wheel 46 in left side and the trailing wheel 14B slow action of rotating speed than the front-wheel 29 and the trailing wheel 14A on right side.See Fig. 1,2,3,4.
C, when vehicle backing,
Handle gear-change hand lever 107, power cooperates location axle pin 50B through reverse linking bar 50D, lever pivot pin 50A, transmission arm 50C is then by under the promotion of transmission arm 50C to reversing pull bar 50, drive drive assembly 1 before and after being positioned at, reversing pull bar 50 on 11 will be stirred weight shaft bearing 90,94 moving left, can do the moving to the right on Fig. 4, be fixed in sleeve on the coupler bearing seat 2 90 and will promote to be fixed in key tooth being moved to the left on tooth cover and axle 2 91 right-hand members on axle 3 87 left ends along tooth interplanting sliding type, spring 88 is compressed, the key tooth separating tooth of axle 2 91 overlaps and makes axle 3 87 and axle 2 91 present released state.The operating state that unpowered state when the single freewheel 3 86 on right side and front-wheel 29 thereof and trailing wheel 14A are neutral gear or pulley-type rotate, the power of reversing can be through this assembly 1,11, promptly before when axle 3 87 and axle 2 91 present released state, the tooth portion at the axis hole place that the double wedge of three-jaw hoof 95A can insert in the perforation of coupler shell 96, tooth portion and driving pulley 80 left surfaces of axle housing 95B have is meshed.At this moment driving pulley 80 around axle 2 91 rotate will driving shaft shell 95B, three-jaw hoof 95A, coupler shell 96 synchronously rotates and promotes drive pulley 98 around axle 2 91 and do synchronous rotation.Drive pulley 85 then is not subjected to this power transmission.Thereby drive the V-type endress belt 26,15 in left side and the front-wheel 46 and the trailing wheel 14B reversing in driving left side, thereby realize reverse action; At this moment off front wheel 29 and off hind wheel 14 are the operating state that pulley-type rotates.See Fig. 1,2,3,4,5.
