摘要： A paving machine for laying a mat of paving material on a paving surface includes a generator, such as a switched reluctance generator, integrally installed with a pump drive and operatively connected to an output shaft of a power source of the paving machine. The generator outputs AC power to a power converter that in turn outputs DC power for a plurality of screed heating elements to produce heat to warm a screed. The paving machine may also include an insulation monitoring system for determining the occurrences of ground faults in the electrical components by comparing current levels in the components to a predetermined maximum current level. A controller of the paving machine may monitor the temperature of the generator and produce the speed of the power source to prevent overheating.

摘要： A paving machine including an adjustable screed assembly is provided. Actuators adjust the screed assembly into the plurality of different configurations. Sensors sense a respective configuration parameter indicative of the configuration of the screed assembly. A controller is configured to save a first set of parameters including the configuration parameters and save a second set of parameters including the configuration parameters in response. The controller is configured to recall one of the first set or second set of parameters, and adjust automatically the configuration of the screed assembly to correspond to the configuration parameters included in the recalled first set or second set of parameters.

摘要： A paving machine for wide-width paving includes a conveyor system, an auger system disposed adjacent to the conveyor system, a screed adjacent to the auger system, and sensing circuitry configured to sense paving material height at one or more of an entrance to the conveyor system and a front side of the auger system to sense or detect underflow or overflow conditions of the paving material. The sensed heights are communicated to control circuitry of the paving machine, through signals from the sensing circuitry, and control circuitry controls rate of movement of one or more of the conveyor system and the auger system.
