Abstract: A system is provided for transmitting torque with speed modulation between a motor generator and an engine. The system includes a first shaft, a second shaft, a first reduction gearset, and a second reduction gearset. The first shaft is configured to rotatably connect with the motor generator. The second shaft is configured to rotatably connect with the engine. The first reduction gearset is rotatably supported at least in part on the first shaft. The first reduction gearset is disposed in selective engagement with the first shaft via a first overrunning clutch disposed therebetween. The second reduction gearset is rotatably supported at least in part on the first shaft and at least in part on the second shaft. The second reduction gearset is disposed in selective engagement with the first shaft via a second overrunning clutch disposed therebetween.

Abstract: A compactor machine includes a frame and at least one compactor drum mounted to the frame. The at least one compactor drum has an outer surface configured for compacting asphalt. A heating system is configured to heat the outer surface and includes a control device configured to control an output of the at least one heating element to the outer surface. A related method for providing a heated drum for a compactor includes mounting at least one heating element and a control device for the at least one heating element to a compactor machine, and coupling the control device with the at least one heating element to enable controlling an output thereof to an outer surface of the compactor drum.

Abstract: A machine system for use in paving a surface includes a supply unit configured to load a transfer machine with paving material from a hopper, and a transfer machine for supplying paving material to a paving machine. The transfer machine includes a receptacle having a recirculation system configured to recirculate paving material and a live floor having a conveyor for discharging paving material to a paving machine. The transfer machine may be compatible for road transport, and may be towed by the supply unit which may be configured for transport within the transfer machine.

Abstract: A worksite preparation method includes moving a compactor machine across at least one region of a worksite, and sensing values indicative of a compaction response of work material in a compacted region. The method also includes generating a machine traffic plan in real time responsive to the sensed values, outputting control signals corresponding to the machine traffic plan and taking a worksite fill action responsive to the control signals.

Abstract: A vehicle with a compound steering system has the ability to reorient both a forward and aft steering axis with respect to a chassis. The compound steering system is controlled in a manner in which one of a forward steering actuator and an aft steering actuator will reach its mechanical limit before the other, when a steering command from an operator input results in an oversteer condition. An oversteer feedback system provides an indication to the operator that the vehicle is in a oversteer condition, such as by increasing the rotational resistance level of the steering wheel to a medium level when in an oversteer condition.

Abstract: A work machine for removing asphalt from a roadway is disclosed. The work machine includes a removal device configured to remove asphalt from a roadway. The work machine also includes a storage bin operatively connected to the removal device and configured to house the removed asphalt.

Abstract: A work machine for removing asphalt from a roadway is disclosed. The work machine includes a plurality of blade members to remove asphalt from the roadway. The plurality of blade members are interconnected by way of hinges.

Abstract: A work machine for removing asphalt from a roadway is disclosed. The work machine includes a removal device configured to remove asphalt from a roadway surface, and a grinding device configured to fracture the removed asphalt. The work machine also includes a funnel-shaped ramp configured to guide the removed asphalt from the removal device to the grinding device. A width of the removal device is larger than a width of the grinding device, and the funnel-shaped ramp is configured to fold the outer edges of the removed asphalt over itself before the removed asphalt reaches the grinding device.

Abstract: A method is provided for controlling a vibratory mechanism. The method includes sensing a vibratory amplitude of the vibratory mechanism and determining a decoupling point of the vibratory mechanism. An output signal is generated based on the determination of the decoupling point for controlling the vibratory amplitude of the vibratory mechanism.

Abstract: Work machines such as road mills having a frame supported by tracked or wheeled ground engaging support units may require the ability to move one or more of the ground engaging units between projecting and retracted positions relative to the frame without reversing the running direction of the repositioned unit. A disclosed work machine has a machine frame supportable by a plurality of ground engaging units. A support device connected between the machine frame and at least one of the ground engaging units has a lifting column adapted to controllably raise and lower the ground engaging unit relative to the frame. A first actuator is connected to the support device to move the one ground engaging unit between the projecting and retracted positions, and a second actuator is connected to the lifting column to maintain the running direction of the associated ground engaging unit in each of the projecting and retracted positions.

Abstract: A method and apparatus for winding up barbed wire from a field by utilizing a prime mover with a reel operatively rotatably attached to a forward portion thereof. A motor is operably attached to the reel for selectively controlling the rotation of the reel. A funnel-shaped guide member is attached to the prime mover in front of the reel for guiding the barbed wire onto the reel, whereby the prime mover may be driven forwardly as the motor rotates the wheel to wind the barbed wire onto the reel while at the same time the prime mover may be steered to the left or right as needed to cause level winding of the barbed wire onto the reel.
