2-4 is contacted with second bevel gear 2-6 by the way of Vertical Meshing, and then the cylindrical cam 1-2 on jackshaft 1-1 is driven to turn
It is dynamic, to be moved along cylindrical cam 1-2 overhead cam track grooves 1-2-1 with moving cam tracking bar 1-4, and then drive be fixed on it is convex
Crossbeam 1-6 is adjusted on wheel tracking bar 1-4 to move back and forth along the linear guide, and then is driven and adjusted the rolling in crossbeam 1-6 grooves
Dynamic bearing 1-12 is moved back and forth, and rolling bearing 1-12 passes sequentially through fine tuning screw rod 1-8, adjusting slider 1-9, swinging crossbeam 1-10
Front-wheel support 1-15 is set to swing, the final swing for realizing front-wheel 1-17 reaches carbon-free trolley turning function.
When needing to adjust the size of S zag trajectories, adjusted by positions of the mobile friction wheel 3-1 on driving shaft 3-3
Friction pulley 3-1 and frictional disk 2-1 rubs on the frictional disk 2-1 of frictional disk 2-1 different radiis position, reach driving shaft 3-3 and
The different drive ratios of transmission shaft 2-2, and then drive first bevel gear 2-4 rotations, first bevel gear 2-4 and second bevel gear 2-6
It is contacted by the way of Vertical Meshing, drive cam drive 13, slider driving gear 12 and adjusts steering micro-adjusting mechanism 11,
The hunting frequency that front-wheel 1-17 is adjusted eventually by front wheel drive bar 1-14 is led to since the forward speed of trailing wheel 5-5 at this time is certain
The hunting frequency of front-wheel 1-17 is overregulated, the size of S zag trajectories can be adjusted.
When needing to adjust the shape of S zag trajectories, screw rod 1-8 is finely tuned by adjusting, rotary fine adjustment screw rod 1-8, which changes, to be adjusted
Positions of the sliding block 1-9 in swinging crossbeam 1-10 grooves, the i.e. relative position of adjusting slider 1-9 and swinging crossbeam 1-10 are saved, from
And change the amplitude of fluctuation of front-wheel 1-17, by the amplitude of fluctuation of front-wheel 1-17, the shape of S zag trajectories can be adjusted.
When needing to adjust the position of S zag trajectories, by adjusting pointer 1-18 and the dial 6-9 on chassis assembly 6
On graduation position, trolley homeposition can be defined；Screw rod 1-8 is finely tuned additionally by adjusting, changes adjusting slider 1-9 and is putting
Position in dynamic crossbeam 1-10, the i.e. relative position of adjusting slider 1-9 and swinging crossbeam 1-10, to realize steering micro-adjusting mechanism
Front-wheel 1-17 amplitude of fluctuation, and then reach adjust S zag trajectories position.
