Driven gear 14 in drive shaft 15 rotates, and to which driving wheel 13 rolls, driving trolley advances, and simultaneously the second circle wheel 2 exists
The first gear piece 10 can be engaged with first gear 9 during rotation, and first gear 9 rotates, and to drive reversing shaft 6 to rotate, be needed
To illustrate that the direction of winding of the reel 8 at 6 both ends of reversing shaft is opposite, when the rotation of reversing shaft 6, left end around
Line wheel 8 coils the second drawstring of the left side 11, pulls cross bar 17 to rotate by the second drawstring 11.Accordingly, left steering wheel 16 rotates.Together
When, right end reel 8 releases the right 11 line of the second drawstring, and cross bar 17 is enable to rotate.Accordingly, right turn wheel 16 rotates.Assuming that this
When cross bar 17 be not parallel to reversing shaft 6, angle is 17 steering locking angle degree half of cross bar, and angle is open to the left.So at this moment small
Vehicle movement bending to the right, bending radius is increasing, and when 10 center tooth of the first gear piece is engaged with first gear 9, trolley is instantaneous
For linear motion, bending radius is infinity.Then, trolley movement bending to the left, bending radius is smaller and smaller, when the first gear piece
10 when engaging disengaging with first gear 9, and trolley bending radius is minimum.At this moment, arc plate 5 pushes sliding block 26 on the first circle wheel 3, makes
Spring leaf 25 has checked rubber wheel 27, and to check reversing shaft 6, at this moment cross bar 17 is not parallel to reversing shaft 6, and angle is cross bar
