摘要： An apparatus is disclosed for controlling the propulsion and steering of a machine. The machine includes a hydrostatic system that drives a pair of ground engaging traction devices. An electronic controller receives operator signals indicative of a desired travel speed and direction, and determines a desired rotational speed of the ground engaging traction devices. The electronic controller produces command signals indicative of the determined speeds to regulate the speed of the ground engaging traction devices to the desired speed.

摘要： An apparatus for controlling a material feed system of a paver is disclosed. The material feed system includes a feeder conveyor and a spreader auger. The apparatus includes a sensor that monitors the amount of material at the edge of the screed and responsively produces an actual material height signal. A rotary switch produces a desired material height signal indicative of a desired amount of material at the edge of the screed. A controller receives the actual and desired material height signals, determines a desired rotational speed of the auger in response to the difference between the signal magnitudes, and produces a command signal to rotate the auger at the desired speed. An electrohydraulic system receives the command signal and rotates the auger at the desired rotational speed.

摘要： In one aspect of the present invention, a control system for a floating screed assembly for an asphalt paving machine is disclosed. The screed assembly includes a main screed and extension screed unit. An electrohydraulic device extends and retracts, as well as, raises and lowers the extension screed unit relative to the main screed unit. The electrohydraulic device additionally pivots the extension screed unit relative to the main screed unit about a horizontal axis. Position sensors produce position signals in response to the position of the extension screed unit. A controller receives the position signals and produces command signals to control the extending, retracting, and pivoting of the extension screed unit to a desired position.

摘要： A fumes abatement system for an asphalt paving machine is disclosed for dispelling noxious fumes that are emitted from asphalt in the hopper of and from behind the paving machine during paving operations. The fumes abatement system utilizes existing plate walls of the feeder tunnel and superstructure to eliminate additional parts and for increased durability. A high capacity blower and a tall exhaust stack are used to disperse the fumes well above the operators of the machine.

摘要： A track supporting roller apparatus supports the articulated track chain of an undercarriage assembly of a track-type work machine. Vibrations and shock loads are generated to a track-type work machine when load bearing track rollers contact the articulated joints of the track chain and the born load is not picked up by an adjacent track roller. The subject roller apparatus has track rollers spaced to support the track chain and prevent the introduction of vibrations and shock loads.

摘要： In one aspect of the present invention, a method for controlling the steering of a directionally steered machine having a hydrostatic system that drives a plurality of driven wheels is provided. The method includes the steps of producing a steering angle signal indicative of the angle of the steered wheels and a wheel speed signal indicative of the rotational speed of the driven wheels, and generating a programmable curve that represents the resulting driven wheel speeds as a function of the angle of the steered wheels. The generated curve is then stored in a software map to be later used to determine the driven wheel speeds based on the angle of the steered wheels.
