Latest Patents

Farr's latest patents include innovative technologies such as the "Slew Drive Control" and the "Paving Machine with Smart Steering Control." The Slew Drive Control patent describes a slew drive that incorporates a bushing interfacing with a drive gear. This bushing is designed to resist loads from the drive gear and is made from a high-strength aluminum bronze alloy. The paving machine utilizes multiple slew drives to control the angle of a pivot arm and the steering of a track. A method for reducing component failure in the paving machine is also outlined, which involves determining an angular position error of the slew drive. If the angular position exceeds a specified tolerance, the system calculates the rate of change of the angular position to ascertain whether the slew drive is rotating. If it is not rotating, the slew drive is driven in reverse to unseize it. The control loop manages both the track drive and the slew drive of the pivot.

The second patent, the Paving Machine with Smart Steering Control, introduces a system that receives path elements corresponding to the current and future positions of the machine. By comparing these elements, the system derives an expected completion time for transitioning from the current position to the future position. This smart steering control system synchronizes the adjustments of the machine's steerable tracks, functioning as a virtual tie rod. This innovation prevents damage, enhances traction control, and preserves the operating life of the machine's components.
