Wheel Block Drives for AGVs

Wheel block drives for automated guided vehicles (AGVs) are critical components that enable the vehicle's mobility and maneuverability. These drives are designed to provide the necessary power and control to navigate the AGV through its intended pathways accurately and efficiently. Below, we will explore the components, types, and considerations for wheel block drives in AGVs.

Components of A Wheel Block Drive

A typical wheel block drive for an AGV consists of several key components:

 • Housing: The wheels are totally machined, and made of spheroidal cast iron material SG-700/2, which encloses and protects the internal components of the wheel block drive.

 • Bearings and Axles: Bearings and axles support the wheel and facilitate smooth rotation. They must be robust enough to withstand the weight of the AGV and any loads it carries.

 • Brake: Integrated brakes are crucial for stopping the wheel when necessary, ensuring the AGV can halt safely and precisely at predetermined locations.

 • Motor: The motor is responsible for generating the torque needed to propel the vehicle. Commonly used motors include DC brushed, DC brushless, AC induction, and servo motors. The choice of motor depends on factors such as power requirements, speed, efficiency, and the need for precise control.

 • Gearbox: The gearbox reduces the motor's high-speed rotation to a lower speed while increasing torque. This is essential for effective traction and control.

 • Encoder: Encoders provide feedback about the position and speed of the wheel to the vehicle's control system. This information is crucial for accurate navigation and positioning.

 • Wheel: The wheel itself can vary in size, material, and tread pattern depending on the surface and load capacity. Wheels are often made of rubber, polyurethane, or steel.

Considerations for Choosing Wheel Block Drives

When selecting wheel block drives for AGVs, several factors should be considered:

 • Load Capacity:The weight of the payload and the vehicle itself must be supported by the wheel block drive.

 • Floor Surface: The type of flooring can impact traction and wear on the wheel. Hard, smooth surfaces may require different wheels than those used on carpet or uneven terrain.

 • Speed and Acceleration: The maximum speed and acceleration capabilities of the AGV are determined by the motor and gearbox.

 • Precision and Control: The need for precise positioning and control influences the type of motor and encoder chosen.

 • Maintenance and Durability: The expected lifespan and maintenance requirements of the wheel block drive should align with the operational needs of the AGV.

 • Integration and Compatibility: The wheel block drive should seamlessly integrate with the rest of the AGV's systems, including the control electronics and software.

By carefully considering these factors, you can select the right wheel block drives to ensure your AGV operates efficiently and reliably in its designated application.
