  • Patent number: 11149388
    Abstract: 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.

  • Publication number: 20210077934
    Abstract: Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. The filter bag assemblies include a flange assembly, a cage attached to the flange assembly, and a filter bag installed over the cage with an opening at the flange assembly. When installed in the dirty air chamber of the air filter system, a seal between the flange assembly and the tubesheet defining the dirty air chamber is provided by applying a seal force on the end of the filter bag assembly located proximate the access panel on the side of the dirty air chamber opposite the tubesheet. That seal force is transmitted to the flange assembly through the cage. The tubular filter bags may be in the form of triangular bags and/or may include bag support connectors at the closed end of the bag.

  • Patent number: 10822025
    Abstract: A hydraulic valve module (2000) for a vehicle (10) is configured to receive hydraulic pressure from a first pump (61) via a first pump inlet (2205) in a first interface surface when connected to a first adjacent module (1000), and from a second pump (62) via an external port (2006). The module (2000) combines both flows to supply a work function circuit (40) of a vehicle via a port (2301) formed in a second interface surface to communicate with a second adjacent module (3000). The module (2000) prioritises flow from the second pump (62) to a steering circuit (50) over the work function circuit, and restricts flow from the first pump (61) to the work function circuit to prioritise and maintain pressure in the first adjacent module upstream of the first pump inlet (2205) which may supply service brake and cooling fan circuits (21, 22, 30) of the vehicle.
