The locomotion system of industrial mobile robots (AGV/AMR) plays a critical role in determining load capacity, operational stability, positioning accuracy, and service life. Among all components, the AGV drive wheel, gearbox, and slewing bearing form the core of the motion system, directly affecting performance and reliability in complex industrial environments.
With the evolution of AGV technology, integrated steering drive wheels have become the mainstream solution. The PLT198 horizontal AGV drive wheel from Shanghai Plutools integrates drive, transmission, and steering into a single compact unit, significantly simplifying system design and reducing engineering risks.
As a Top 3 AGV drive wheel manufacturer in China, Plutools has delivered large-scale solutions for global AGV and AMR manufacturers, offering high-reliability drive systems for demanding industrial applications.
1. AGV Drive Wheel Selection Principles
The AGV drive wheel is the core execution component responsible for:
Load transfer
Traction output
Motion guidance
The selection logic focuses on matching:
Total vehicle load
Working conditions
Drive configuration
For integrated systems like the horizontal steering drive wheel, the drive wheel is deeply coupled with the gearbox and slewing mechanism, making system-level matching essential.
1.1 Key Parameters of AGV Drive Wheels
Wheel Size (Diameter × Width)
Affects obstacle-crossing ability, speed, and load distribution
Rated Load Capacity
The most critical parameter, defining the allowable load per wheel
Wheel Material
Polyurethane (PU) is widely used, especially 80A hardness patterned PU, balancing traction, wear resistance, and shock absorption
Drive Configuration Compatibility
Includes:
Unidirectional AGV
Bidirectional AGV
Omnidirectional AGV (4WD differential)
Single or dual steering drive layouts
1.2 Load Classes of AGV Drive Wheels
| Class | Rated Load per Wheel | Max AGV Load | Application |
|---|---|---|---|
| 1 | 800 kg | ≤1600 kg | Light-duty AGV |
| 2 | 1500 kg | ≤3000 kg | Standard industrial AGV |
| 3 | 2000 kg | ≤4000 kg | Heavy-duty AGV |
| 4 | 3000 kg | ≤6000 kg | Industrial heavy-duty |
| 5 | 5000 kg | ≤10000 kg | Ultra heavy-duty AGV |
The PLT198 horizontal AGV drive wheel (1500 kg) is a typical Class 2 solution and one of the most widely used configurations in global AGV projects.
It supports:
Single drive + caster layout → compact AGV chassis
Dual steering drive layout → zero-turn omnidirectional movement
1.3 Safety Factor Calculation
For AGV drive wheel selection:
Normal conditions → Safety factor ≥1.2
Heavy-duty conditions → Safety factor ≥1.5
Formula:
F_actual = (G_total × K_condition × λ_distribution) / (n × μ)
Safety factor:
S = F_rated / F_actual
Application Example (PLT198 AGV Drive Wheel)
For a 2800 kg AGV with dual PLT198 units:
Epoxy floor → ~1517 kg per wheel
Anti-slip floor → ~1300 kg per wheel
In practical engineering, controlling load to ~1200 kg per wheel ensures long-term stable operation.
This configuration has been successfully deployed in 500+ AGVs for overseas customers, proving its reliability.
1.4 AGV Application Scenarios
Light-duty AGV → Class 1 drive wheels
Standard industrial AGV → PLT198 recommended
Omnidirectional AGV → multi-drive configurations
Low-profile AGV → horizontal drive wheel + casters
2. Integrated Gearbox Advantages in AGV Drive Wheels
Traditional AGV systems require independent gearbox selection.
The PLT198 integrates a precision planetary gearbox, optimized for AGV drive wheel applications.
Key Benefits:
Optimized gear ratio (12–50)
High torque output for heavy loads
Strong radial load capacity
Maintenance-free design
Performance:
High rigidity transmission
Backlash <3 arcmin
Positioning accuracy up to:
±5 mm (no-load)
±8 mm (full-load)
3. Integrated Steering System (Slewing Bearing)
The steering function of an AGV drive wheel relies on the slewing bearing.
In the PLT198 horizontal AGV drive wheel, this is fully integrated.
Advantages:
High load capacity (≥1.5 safety factor)
High steering precision (±0.1°)
Sealed, maintenance-free structure
Easy installation with standard flange
4. Global Applications of PLT198 AGV Drive Wheel
The PLT198 AGV drive wheel is widely used in:
1.5-ton AGV systems (dual steering drive)
3-ton production line robots
Heavy-duty AMR platforms
A recent overseas order of 500 units further demonstrates:
Product consistency
Manufacturing capability
Global market recognition
Conclusion
The AGV drive wheel is the most critical component in mobile robot locomotion systems.
By integrating drive, gearbox, and steering into one unit, the PLT198 horizontal AGV drive wheel from Shanghai Plutools provides:
