摘要： A rotary pivot arm positioning assembly for a paving, texturing, or curing machine allows the machine to automatically transition from an operational orientation to a transport orientation without manual repositioning or disconnection of its components. The assembly includes a pivot arm coupled to both the front and aft ends of an end frame by a helical actuator, slew gear drive or other rotary actuator. The rotary actuator articulates each pivot arm, as well as the adjustable leg and steerable crawler connected to the pivot arm, through at least a 90-degree range. The end frame may be fixed to the left or right end of the machine. The assembly may additionally include a second helical actuator, slew gear drive or rotary actuator connecting each steerable crawler to the adjustable leg and configured to rotate the steerable crawler through a full 360 degrees.

摘要： A slew drive includes a bushing interfacing with a drive gear. The bushing resists a load from the drive gear. The bushing includes an aluminum bronze alloy with a high strength. A paving machine includes multiple of the slew drives. The slew drives control an angle of a pivot arm and steering of a track. A method of reducing component failure in the paving machine includes determining an angular position error of the slew drive of the track. If the angular position exceeds a tolerance, a rate-of-change of the angular position is found to determine whether the slew drive is rotating. Where the slew drive is not rotating, the slew drive is driven in a reverse direction to unseize the slew drive. A track drive and the slew drive of the pivot are controlled by a control loop. The slew drive may be dithered to steer a trailing pivot.
