AI Technical Summary
Traditional electric flatbed carts are prone to wheel suspension on uneven ground, which leads to unstable power transmission, increases safety risks, and limits their application in complex terrain.
It adopts a tight connection between a dual-output shaft motor and a steering gearbox, and realizes power transmission through a coupling. Combined with a through-shaft drive wheel set, it ensures four-wheel drive. The steering gearbox is equipped with gears that mesh precisely with the drive gears to solve the problem of power loss.
It enables stable driving on uneven ground, improves operational reliability and applicability, and ensures stable driving in complex terrains such as construction sites and mine tunnels.
