This type of vehicle generally has a special design that allows multi-directional movement, which helps to improve the efficiency and flexibility of logistics operations. Four-way logistics vehicles are widely used in some logistics environments that require frequent direction adjustments or operations in narrow spaces. In order to allow the four-way logistics vehicle to move better, a transmission device is required to enable the wheels of the logistics vehicle in four directions to rotate better. To this end, a transmission device for a four-way logistics transport vehicle is proposed.
