Differential Steering Two Drive Wheel DC Motor Actuator

Differential Steering Two Drive Wheel DC Motor Actuator

●  Introduction

A differential steering drive wheel is a two-wheel drive system in which each wheel is equipped with an independent actuator, such as a DC motor. The name originates from the fact that the vehicle's motion vector is the result of the combined movements of the two independently driven wheels. By controlling the two drive motors to rotate in opposite directions or at different speeds, the motor torque is transmitted through a gearbox and polyurethane-coated wheels, causing the two wheels within the differential drive unit to rotate oppositely or at different speeds. This generates the required steering angle and enables vehicle maneuvering.

Features

Superior Load Capacity and Driving Performance

Compared with other drive solutions of the same class, differential steering drive wheels provide higher load capacity, greater traction force, and higher travel speeds, making them ideal for heavy-duty and high-intensity applications.


Exceptional Maneuverability

The vehicle can move smoothly and freely in virtually any direction, making this solution particularly suitable for operation in narrow aisles, confined spaces, and complex routing environments.


Reduced Vehicle Height

The low installation height enables the design of thinner AGVs/AMRs with a lower center of gravity, expanding vehicle design flexibility and application possibilities.


Significantly Extended Tire Service Life

During on-the-spot steering, the wheels maintain rolling contact with the ground rather than the sliding or static friction commonly found in conventional steering axles. This minimizes floor wear and substantially reduces tire abrasion, resulting in a longer service life for polyurethane-coated wheels.


Combination of Technical Excellence and Application Value

Advantages: Differential steering drive wheels are particularly well suited for applications requiring high maneuverability, heavy-load capability, low floor wear, and extended tire life.
