Differential steering

nounStandard termMechanical

A steering method that turns a vehicle by driving the wheels or tracks on each side at different speeds.

This system eliminates the need for steerable axles. By varying the torque and speed applied to the left and right drive wheels, the vehicle pivots around its vertical axis. If the tracks or wheels are driven in opposite directions, the vehicle can execute a zero-radius turn, making it highly maneuverable in tight spaces.

Heard on the job

We need to check the hydraulic motors on the left side because the differential steering is pulling hard to the right.

Insider tip

This setup causes the tires or tracks to drag sideways during a turn, which accelerates tread wear on hard surfaces.
