Abstract

The invention provides a heavy-duty electric driven all-wheel steering and all-wheel driving unmanned framework transport vehicle. The heavy-duty electric driven all-wheel steering and all-wheel driving unmanned framework transport vehicle comprises a frame assembly for placing cargoes, and further comprises a steering assembly, a driving axle assembly and a suspension assembly, wherein the steering assembly comprises a steering oil cylinder I, a steering oil cylinder II, a frame connection plate, two active steering structures and an oil cylinder connection seat which is fixedly mounted on the frame assembly; the frame connection plate is in rotary connection with the frame assembly; oil cylinder rods and tail parts of the steering oil cylinder I and the steering oil cylinder II are in rotary connection with the frame connection plate and the oil cylinder connection seat respectively; the two active steering structures are in rotary connection with the frame assembly respectively andare in rotary connection with two sides of the frame connection plate through connection rods I respectively; the suspension assembly comprises a suspension oil cylinder and a balance arm. According to the heavy-duty electric driven all-wheel steering and all-wheel driving unmanned framework transport vehicle provided by the invention, the problems in the prior art that a driving wheel of an existing heavy-duty AGV (Automatic Guided Vehicle) cannot rotate so that steering operation resistance is great and a tire of the driving wheel is abraded are solved.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular, to a heavy-duty electric drive all-wheel steering all-wheel drive unmanned frame transport vehicle. Background technique [0002] AGV (Automated Guided Vehicle means "Automated Guided Vehicle") is a transportation device with unmanned automatic guidance device, which can drive along the prescribed guidance path, has safety protection and various transfer functions, and is an industrial robot. of a type. The salient feature of AGV is unmanned driving, which can ensure that the system can drive automatically without manual navigation. Good flexibility, high level of automation and intelligence, self-diagnosis and troubleshooting, reducing maintenance personnel costs. The entire AGV system can realize intelligent scheduling, keep the production order busy and orderly at all times, and greatly save personnel management costs. [0003] At present, there are many mature appl...
