The structural form of the AGV trolley generally includes three aspects: the number of axles, the drive form and the steering form.
(1) Single drive
Single-drive structure is mostly used for three-wheeled vehicle body structure, which can realize the AGV car's forward, backward, and left and right turn (the corner is generally less than 90 *). The structure of the three wheels has good grip and low ground requirements, and is mostly used for small AGV robots.
(2) Differential drive form
Differential form of car body turning is achieved by the speed difference between two active drive wheels, which can realize the car's forward, backward, turn left and right (turn angle is greater than 90 °), spin in place, the effect of turning is better than single drive Good form.
(3) Double drive form
The dual-drive form can realize the whole vehicle's forward, backward, and all-directional steering. The main advantage is that it can control any change of the body attitude during the movement. It is mostly used in environments and occasions with small passages or special requirements for the direction of work. The disadvantage is that the flatness of the ground is higher, and the adaptability of the car is relatively poor, so it is not suitable for outdoor work and the cost is relatively high.
(4) Multi-wheel drive
Multi-wheel drive is mostly used for eight-wheel models. Four driving wheels are also steering wheels, and four driven wheels support and steer. It can achieve overall forward, backward, and all-directional driving. It is more used in heavy-duty industries. Complex, difficult to control, and more expensive.
