Description

Supporting wheel suspension structure of self-adaptation AGV

Technical Field

The utility model relates to a AGV supporting wheel hangs the field, particularly, relates to a supporting wheel suspended structure of self-adaptation AGV.

Background

In the AGV (automated Guided vehicle) solution, the smoothness of the AGV operation depends largely on the flatness of the floor. In practical situations, the ground in an AGV environment is difficult to achieve absolute flatness or even a certain slope under ideal conditions. Currently, the above problems are mainly solved by using shock absorbing casters or by adding or subtracting shock absorbers on the supporting wheels. Although the adaptability of the AGV to the ground is enhanced to a certain extent through the mode, the supporting height of the vehicle body can be changed under the load condition, the stability of the vehicle body is lowered, and particularly the influence is obvious under the load offset condition.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a supporting wheel suspended structure of self-adaptation AGV to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a supporting wheel suspended structure of self-adaptation AGV, hangs the board including the truckle, and the truckle hangs the board and links to each other with the universal wheel through the truckle mounting panel, and the universal wheel is installed at the truckle and is hung the both ends of board.

Furthermore, the caster wheel suspension plates are connected through the supporting points of the caster wheel suspension shafts to form a suspension structure swinging around the supporting points.

Furthermore, the truckle suspension shaft is fixed on the AGV through truckle suspension base, and truckle suspension base is last to be equipped with truckle suspension locking screw.

Furthermore, a deep groove ball bearing and a thrust ball bearing are arranged at the fulcrum of the caster suspension shaft and bear radial and axial pressure.

Furthermore, the deep groove ball bearings and the thrust ball bearings are symmetrically arranged on the caster suspension bearing seat, and the deep groove ball bearings and the thrust ball bearings adjust the clearance between the outer rings of the bearings through caster suspension bearing covers and caster suspension bearing washers.

Further, the caster suspension plate is connected with the caster mounting plate through a caster suspension plate mounting screw.

Furthermore, a round nut is arranged on the caster wheel suspension bearing cover, and a round nut stop washer is arranged on the round nut.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) due to the non-spring type suspension structure, the AGV running stability is slightly influenced by the load and the gravity center position of the load;

(2) due to the non-spring type suspension structure, the problem of counterweight does not need to be considered when the AGV is not loaded;

(3) the suspension can automatically adapt to the fluctuation of the ground according to the change of the ground, and the AGV body can still keep stable.
