In the figure: 1. the device comprises a driving assembly, 2, a swing shaft pin, 3, a chassis fixing piece, 4, a wheel, 5, a damping assembly, 6, a connecting frame, 7, a guide pillar, 8, a threaded adjusting rod, 9, a damping spring, 10, an adjusting nut, 11 and a rotating hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in FIG. 1, the differential damping structure of AGV comprises a chassis fixing piece 3 and a damping assembly 5, wherein the damping assembly 5 is installed between the chassis fixing piece 3 and a frame, and a driving assembly 1 and wheels 4 are installed at the bottom of the chassis fixing piece 3.
The one end of chassis mounting 3 is equipped with rotates hole 11, install swing pivot 2 in the rotation hole 11, chassis mounting 3 rotates through swing pivot 2 and connects AGV automobile body chassis, damper 5 installs the one end of keeping away from swing pivot 2 at chassis mounting 3, damper 5 and swing pivot 2 set up the both ends at chassis mounting 3, consequently, when chassis mounting 3 takes place the slope, damper 5 also can play fine cushioning effect, and the in-process that traveles at the AGV automobile body, if the ground height is uneven, wheel 4 can shake from top to bottom and lead to the automobile body chassis front and back to relapse the slope, consequently this damper 5 this moment can provide the cushioning effect, avoid the wheel card to die subaerially at injustice.
A threaded adjusting rod 8 is fixed on the connecting frame 6, a guide post 7 is fixed on the top of the chassis fixing part 3, two ends of a damping spring 9 are respectively sleeved on the outer walls of the threaded adjusting rod 8 and the guide post 7, so that the connecting frame 6 is elastically connected with the chassis fixing part 3, the threaded adjusting rod 8 is movably connected with the connecting frame 6 up and down, one section of the threaded adjusting rod 8 positioned below the connecting frame 6 is provided with a limiting block, one section of the outer wall of the threaded adjusting rod 8 positioned above the connecting frame 6 is sleeved with an adjusting nut 10, the adjusting nut 10 is rotated to adjust the distance between the threaded adjusting rod 8 and the guide post 7, the threaded adjusting rod 8 and the guide post 7 are inserted into the damping spring 9, so that the damping spring 9 can not generate gravity center offset, the accident that the damping spring 9 is misplaced to cause failure is avoided, the threaded adjusting rod 8 can be adjusted by the, the length of the damping spring 9 can thus be varied to adjust the damping amplitude, the shorter the length of the damping spring 9 is compressed, the smaller the damping amplitude, and the longer the damping amplitude, and thus the damping effect of the damping assembly 5 can be artificially adjusted.
The device is installed between the frame and the chassis of AGV automobile body, link 6 is fixed on the frame, chassis mounting 3 is fixed on the chassis through swing pivot 2, make this chassis mounting 3 and chassis can take place the swing, because the mounted position of damper 5 and swing pivot 2 is relative, even consequently wheel 4 traveles on uneven road surface, it rocks to drive whole chassis mounting 3, can not die with the chassis card yet, guarantee wheel 4 normal use, and damper 5 can also provide shock-absorbing function, if need change damper 5's shock attenuation effect, only need twist adjusting nut 10 and select to compress damping spring 9 to suitable length can.
