20100326067 | SELF-PROPELLED MACHINE - In a self-propelled machine F for processing paving material, the machine having a liquid cooled combustion engine M and at least one hydraulic circuit H containing hydraulic pumps | 12-30-2010 |
20100329783 | ROAD FINISHER WITH AUTOMATIC ENGINE CONTROLLER - The invention relates to a self-propelling machine for processing bituminous or concrete pavement material, in particular a road finisher or a feeder. The machine comprises an internal combustion engine as a primary drive source, a controller for the engine, said controller receiving control signals, at least one additional drive unit for functional and operational components of the machine as well as at least one hydraulic circuit comprising a hydraulic medium reservoir. The invention is characterized in that the controller is configured for automatically causing starting and/or stopping of the engine in response to receipt of at least one specific control signal. | 12-30-2010 |
20110126533 | METHOD FOR CLOSED-LOOP POWER CONTROL OF A ROAD FINISHING MACHINE OR FEEDER AND A ROAD FINISHING MACHINE OR FEEDER COMPRISING THE SAME - In the hydrostatic working operation of a road finishing machine or a feeder which comprises a primary power plant with an internal combustion engine (M) and several hydraulic variable displacement pumps, which are hydraulically connected to hydraulic motors of working components, and which possesses a computerized control device, the internal combustion engine is operated within its engine-specific characteristic map in response to the load condition by dynamic speed adaptation in a characteristic zone with optimal consumption, and the displacements (V | 06-02-2011 |
20120031724 | ROAD FINISHING MACHINE AND METHOD OF OPERATING A ROAD FINISHING MACHINE - In a road finishing machine with a primary power plant and a power transfer to a hydraulic pump and/or a generator for supplying power to hydraulically or electrically operated functional components, the power transfer comprises at least one clutch that can be optionally engaged and disengaged, and a clutch control device is provided by means of which, depending on at least the operator guidance and/or a detected clutch loading situation, a disengagement delay (Δt) automatically overriding the operator guidance can be set, and/or a clutch shifting number restriction can be set by means of a detection interval (dt) moving along in time. The clutch control device actually engages, within the frame of the respective overriding control strategy, the clutch only after the disengagement delay (Δt) has lapsed, if no operation command to the contrary is present, and/or keeps the clutch first engaged, although an operation command to the contrary is present. | 02-09-2012 |
20120305232 | CONSTRUCTION MACHINE WITH AUTOMATIC FAN ROTATIONAL SPEED REGULATION - The present invention describes a construction machine with a drive unit and with a cooling system that comprises a fan. The fan is connected to the drive unit by means of a controllable viscous coupling, whereby the viscous coupling can be adjusted in such a way that a required fan rotational speed is set on the output side. The invention furthermore describes a method for the automatic fan rotational speed regulation for a cooling system in a construction machine. | 12-06-2012 |
20130195550 | ROAD FINISHING MACHINE WITH CONTROLLABLE CONVEYOR DEVICES - The invention relates to a road finishing machine with a controllable longitudinal conveyor device and a transverse conveyor device for mixed laying material disposed in the rear in the direction of motion. The road finishing machine furthermore comprises a control unit for adjusting a delivery rate of the longitudinal conveyor device and/or the transverse conveyor device. The control unit is connected with a sensory mechanism for determining a mixed laying material quantity or rate and adjusts the delivery rate in response to a signal from the sensory mechanism representing the mixed laying material quantity or rate. The control unit can be pilot controlled in response to laying parameters by a pilot control unit. | 08-01-2013 |
20130287495 | ROAD FINISHER WITH AUTOMATIC ENGINE CONTROLLER - The invention relates to a self-propelling machine for processing bituminous or concrete pavement material, in particular a road finisher or a feeder. The machine comprises an internal combustion engine as a primary drive source, a controller for the engine, said controller receiving control signals, at least one additional drive unit for functional and operational components of the machine as well as at least one hydraulic circuit comprising a hydraulic medium reservoir. The invention is characterized in that the controller is configured for automatically causing starting and/or stopping of the engine in response to receipt of at least one specific control signal. | 10-31-2013 |
20160090102 | ROAD PAVER WITH OPERATING MODULE AND PROCESS TO ACTIVATE AN OPERATING FUNCTION - The disclosure relates to a road paver with at least one operating module to enter operating commands. The operating module comprises a plurality of buttons that can each be pressed in a contact-based way to enter the respective operating commands in order to activate relevant operating functions of the road paver. According to the disclosure, the road paver further comprises a sensor unit that is designed to detect a distance of an operator to the operating module, whereby this distance determines a space from the operating module to any body part of the operator. The sensor unit is connected to a control unit of the road paver that is configured to already activate at least one of the operating functions of the road paver by means of the output signal as soon as the operator undercuts a predetermined threshold distance in relation to the operating module. | 03-31-2016 |
