    AGV (Automated Guided Vehicle) is a vehicle capable of automatically navigating without human supervision. And the steering wheel is one of the important components in AGV that plays a role in navigation and driving control.


    Working Principle of AGV Drive Wheels


    Classification of AGV Drive Wheels


    AGV Drive Wheels can be divided into the following categories based on their structure and implementation method: 


    • Steering Wheel: Mainly used for front wheel steering, controlling the AGV's turning radius by changing the angle of the steering wheel. 

    • Driving Wheel: Serves as the power source for the AGV, achieving forward and backward movement driven by a motor. 

    • Caster Wheel: Used to support the weight of the AGV, reducing friction between the driving wheel and the AGV steering wheel.



    Working Principle of Traditional Drive Wheels


    Traditional AGV Drive Wheel system usually consists of a motor, reducer, steering mechanism, and brake system. The working principle is as follows:


    • Motor Drive: The steering wheel achieves driving and steering functions through the rotation of the motor. The torque output by the motor is transmitted to the tire through the reducer, generating sufficient power to drive the AGV.

    • Steering Mechanism: The steering mechanism changes the driving direction of the entire vehicle by controlling the rotation angle of the steering wheel according to the steering signal and angle requirements of the AGV.

    • Brake System: The steering wheel is usually equipped with a brake system for emergency stopping or parking fixation. The brake system can be controlled by electromagnetic force or hydraulic pressure.


    Working Principle of New Type Drive Wheels


    With continuous technological advancements, new types of AGV Drive Wheels are beginning to show more innovation and development. For example, the following working principles are adopted in new steering wheels:


    • Intelligent Navigation: Some new steering wheels integrate navigation systems, which can perceive the surrounding environment through technologies like laser or infrared to achieve automatic navigation.

    • Electromagnetic Suspension: Steering wheels employing electromagnetic suspension technology can effectively reduce friction with the ground, improving vehicle driving efficiency and stability.

    • Automatic Driving: New type steering wheels can be used in conjunction with other sensors and control systems to achieve automatic driving functions, enhancing the intelligence level of AGV.


    Drive Wheels Failures and Maintenance


    As a core component of AGV, the failure of the steering wheel will directly affect the navigation and driving control of the AGV. To maintain normal operation of the AGV, the steering wheel needs regular maintenance and inspection. Here are some recommended maintenance measures:


    • Regular Cleaning: Clean the surface of the steering wheel of dust and other contaminants to ensure normal rotation and friction.

    • Lubrication Maintenance: According to the manufacturer's recommendations, add lubricants at appropriate locations and pay attention to the type and amount of lubricant.

    • Tire Inspection: Regularly check the wear condition of the steering wheel tires. If there is severe wear or other damage, replace them in time.

    • Motor and Electrical System Maintenance: Inspect and maintain the steering wheel's motor and electrical system to ensure their normal operation and good connectivity.


    Conclusion


    As a key component of AGV, understanding the working principle of AGV Drive Wheels is very important for understanding the navigation and driving control mechanism of AGV. This article details the working principles of both traditional and new steering wheels and provides corresponding maintenance suggestions.


    We can look forward to more innovations and evolutions in AGV Drive Wheels as technology further develops, bringing more possibilities for the application of automated guided vehicles.



    FAQs about AGV Drive Wheels


    What is the difference between AGV and AMR?


    AGV vs AMR is a common comparison in warehouse automation. AGVs follow fixed paths using magnetic tape, QR codes, or predefined navigation, while AMRs use sensors and SLAM technology to dynamically navigate around obstacles. AGV systems are ideal for predictable, repetitive transport tasks and often use high-torque AGV wheel motors for stable movement under heavy loads. AMRs offer more flexibility, but AGVs remain a cost-effective choice for factories requiring reliable route accuracy and durable AGV wheels.


    What type of motor is used in an AGV drive wheel?


    Most AGV drive wheel systems use brushless DC (BLDC) or servo-based AGV wheel motors because they provide precise speed control, high torque output, and low maintenance requirements. Integrated drive wheel solutions combine the motor, gearbox, brake, and AGV wheels into a compact module, improving efficiency and simplifying AGV design for logistics, manufacturing, and robotics applications.


    How do I choose the right AGV wheel for my application?


    Selecting the right AGV wheels depends on load weight, floor surface, speed, and operating environment. Polyurethane wheels are widely used for low noise and floor protection, while rubber wheels improve grip on uneven surfaces. Matching the correct wheel diameter and AGV wheel motor torque ensures stable navigation, longer wheel life, and better energy efficiency for AGV and AMR systems.


    Why is traction important for AGV drive wheels?


    Traction directly affects AGV safety, positioning accuracy, and transport efficiency. Poor traction can cause slipping, navigation errors, or uneven wear on AGV wheels. High-performance AGV drive wheel systems use optimized tread materials and precision AGV wheel motors to maintain stable traction during acceleration, braking, and cornering, especially in high-load automated material handling operations.
