Description

Floating type driving wheel assembly and AGV forklift Technical Field The utility model relates to the technical field of logistics transportation industry, in particular to a floating driving wheel assembly and an AGV forklift. Background In the technical field of material handling, there are two carrying modes, namely a manned carrying machine and an unmanned carrying machine, wherein the unmanned carrying machine is generally called AGV, and most of electric forklifts in the current market have two fixing modes, namely a fixing mode and a floating mode, of a driving assembly. Chinese patent CN215436689U discloses a single steering wheel of an AGV, comprising a floating mechanism and a steering gear The steering mechanism comprises a driving seat, a steering mechanism and a reinforcing mechanism, wherein the driving seat is provided with a driving device capable of driving the steering wheel to roll, the steering mechanism is arranged on the driving seat and can drive the steering wheel to rotate relative to the axial direction of the floating rod, the reinforcing mechanism is arranged on the upper floating baffle frame, and the driving end of the reinforcing mechanism is connected with the driving seat. However, in the technical scheme, in the full-load running or jolting process, the steering wheel part floats upwards, the frame is subjected to upward force of the floating mechanism, so that the ground grabbing force of the single steering wheel is reduced, but if a booster mechanism is additionally arranged to balance, the weight of the whole automobile is increased, the pressure of the back space layout is increased, and meanwhile, the energy consumption is also increased. Disclosure of utility model The utility model aims at overcoming the defects of the prior art, and provides a specific setting position of a mechanical structure of a floating mechanism, so that when a driving device floats upwards, a bottom plate is subjected to downward acting force of the floating mechanism, the ground grabbing force of the whole floating driving wheel assembly is improved, and in operation, the floating is adjustable, and the problems that the pressure of the back space layout is caused and the energy consumption is high due to the fact that a booster mechanism is additionally arranged to balance the ground grabbing force of a single steering wheel are solved. In order to achieve the above purpose, the present utility model provides the following technical solutions: A floating driving wheel assembly comprises a driving seat, a driving device arranged on the driving seat and a bottom plate connected with a frame; A floating mechanism is arranged between the bottom plate and the driving seat, so that the driving device is controlled to adaptively float up and down by applying acting force to the bottom plate by the floating mechanism. Preferably, when the driving device floats upwards, the bottom plate is subjected to downward force of the floating mechanism.
