What does Harmonic Drive Company do? Learn how its precision gear technology improves machine tools with low backlash, compact design, and accurate motion for better CNC performance.

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.

This vertical drive wheel Motor is designed for AGVs, AMRs, and forklifts with capacities up to 10 tons, covering virtually all forklift types. The most common applications are forklifts with load capacities ranging from 1.5 to 3 tons. With the advancement of the Internet of Things (IoT), LiDAR navigation technologies, and the widespread adoption of 5G, forklifts are gradually evolving from manual operation to assisted operation and ultimately to fully autonomous control. As a result, the transformation of conventional forklifts into unmanned forklifts and AGVs (Automated Guided Vehicles) has become an inevitable industry trend. This vertical drive wheel is developed to accelerate the transition of AGV forklifts through lightweight design, compact structure, and intelligent integration.

Humanoid robotics is often described as a software race, but the real constraint on scaling production to millions of units lies in the physical layer. Robot joints require high-torque, high-efficiency actuators, and actuators depend on high-energy-density NdFeB permanent magnets. The true bottleneck is not simply “rare earths” in general, but the much narrower NdPr-to-magnet supply chain corridor. China dominates the midstream processing and magnet manufacturing sectors, giving it significant influence over the pace, cost curve, and industrial geography of embodied AI.
